§ 401 — Qualified Pension, Profit-sharing, And Stock Bonus Plans

(a) A trust created or organized in the United States and forming part of a stock bonus, pension, or profit-sharing plan of an employer for the exclusive benefit of his employees or their beneficiaries shall constitute a qualified trust under this section— (1) if contributions are made to the trust by such employer, or employees, or both, or by another employer who is entitled to deduct his contributions under section 404(a)(3)(B) (relating to deduction for contributions to profit-sharing and stock bonus plans), or by a charitable remainder trust pursuant to a qualified gratuitous transfer (as defined in section 664(g)(1)), for the purpose of distributing to such employees or their beneficiaries the corpus and income of the fund accumulated by the trust in accordance with such plan; (2) if under the trust instrument it is impossible, at any time prior to the satisfaction of all liabilities with respect to employees and their beneficiaries under the trust, for any part of the corpus or income to be (within the taxable year or thereafter) used for, or diverted to, purposes other than for the exclusive benefit of his employees or their beneficiaries (but this paragraph shall not be construed, in the case of a multiemployer plan, to prohibit the return of a contribution within 6 months after the plan administrator determines that the contribution was made by a mistake of fact or law (other than a mistake relating to whether the plan is described in section 401(a) or the trust which is part of such plan is exempt from taxation under section 501(a), or the return of any withdrawal liability payment determined to be an overpayment within 6 months of such determination)); (3) if the plan of which such trust is a part satisfies the requirements of section 410 (relating to minimum participation standards); and (4) if the contributions or benefits provided under the plan do not discriminate in favor of highly compensated employees (within the meaning of section 414(q)). For purposes of this paragraph, there shall be excluded from consideration employees described in section 410(b)(3)(A) and (C). (A) A classification shall not be considered discriminatory within the meaning of paragraph (4) or section 410(b)(2)(A)(i) merely because it is limited to salaried or clerical employees. (B) A plan shall not be considered discriminatory within the meaning of paragraph (4) merely because the contributions or benefits of, or on behalf of, the employees under the plan bear a uniform relationship to the compensation (within the meaning of section 414(s)) of such employees. (C) A plan shall not be considered discriminatory within the meaning of paragraph (4) merely because the contributions or benefits of, or on behalf of, the employees under the plan favor highly compensated employees (as defined in section 414(q)) in the manner permitted under subsection (l). (i) A defined benefit plan shall not be considered discriminatory within the meaning of paragraph (4) merely because the plan provides that the employer-derived accrued retirement benefit for any participant under the plan may not exceed the excess (if any) of— (I) the participant’s final pay with the employer, over (II) the employer-derived retirement benefit created under Federal law attributable to service by the participant with the employer. (ii) For purposes of this subparagraph, the participant’s final pay is the compensation (as defined in section 414(q)(4)) paid to the participant by the employer for any year— (I) which ends during the 5-year period ending with the year in which the participant separated from service for the employer, and (II) for which the participant’s total compensation from the employer was highest. (E) For purposes of determining whether 2 or more plans of an employer satisfy the requirements of paragraph (4) when considered as a single plan— (i) If the amount of contributions on behalf of the employees allowed as a deduction under section 404 for the taxable year with respect to such plans, taken together, bears a uniform relationship to the compensation (within the meaning of section 414(s)) of such employees, the plans shall not be considered discriminatory merely because the rights of employees to, or derived from, the employer contributions under the separate plans do not become nonforfeitable at the same rate. (ii) If the employees’ rights to benefits under the separate plans do not become nonforfeitable at the same rate, but the levels of benefits provided by the separate plans satisfy the requirements of regulations prescribed by the Secretary to take account of the differences in such rates, the plans shall not be considered discriminatory merely because of the difference in such rates. (F) For purposes of testing for discrimination under paragraph (4)— (i) the social security retirement age (as defined in section 415(b)(8)) shall be treated as a uniform retirement age, and (ii) subsidized early retirement benefits and joint and survivor annuities shall not be treated as being unavailable to employees on the same terms merely because such benefits or annuities are based in whole or in part on an employee’s social security retirement age (as so defined). (G) Paragraphs (3) and (4) shall not apply to a governmental plan (within the meaning of section 414(d)). (6) A plan shall be considered as meeting the requirements of paragraph (3) during the whole of any taxable year of the plan if on one day in each quarter it satisfied such requirements. (7) A trust shall not constitute a qualified trust under this section unless the plan of which such trust is a part satisfies the requirements of section 411 (relating to minimum vesting standards). (8) A trust forming part of a defined benefit plan shall not constitute a qualified trust under this section unless the plan provides that forfeitures must not be applied to increase the benefits any employee would otherwise receive under the plan. (A) A trust shall not constitute a qualified trust under this subsection unless the plan provides that the entire interest of each employee— (i) will be distributed to such employee not later than the required beginning date, or (ii) will be distributed, beginning not later than the required beginning date, in accordance with regulations, over the life of such employee or over the lives of such employee and a designated beneficiary (or over a period not extending beyond the life expectancy of such employee or the life expectancy of such employee and a designated beneficiary). (i) A trust shall not constitute a qualified trust under this section unless the plan provides that if— (I) the distribution of the employee’s interest has begun in accordance with subparagraph (A)(ii), and (II) the employee dies before his entire interest has been distributed to him, (ii) A trust shall not constitute a qualified trust under this section unless the plan provides that, if an employee dies before the distribution of the employee’s interest has begun in accordance with subparagraph (A)(ii), the entire interest of the employee will be distributed within 5 years after the death of such employee. (iii) If— (I) any portion of the employee’s interest is payable to (or for the benefit of) a designated beneficiary, (II) such portion will be distributed (in accordance with regulations) over the life of such designated beneficiary (or over a period not extending beyond the life expectancy of such beneficiary), and (III) such distributions begin not later than 1 year after the date of the employee’s death or such later date as the Secretary may by regulations prescribe, (iv) If the designated beneficiary referred to in clause (iii)(I) is the surviving spouse of the employee and the surviving spouse elects the treatment in this clause— (I) the regulations referred to in clause (iii)(II) shall treat the surviving spouse as if the surviving spouse were the employee, (II) the date on which the distributions are required to begin under clause (iii)(III) shall not be earlier than the date on which the employee would have attained the applicable age, and (III) if the surviving spouse dies before the distributions to such spouse begin, this subparagraph shall be applied as if the surviving spouse is the employee. (C) For purposes of this paragraph— (i) The term “required beginning date” means April 1 of the calendar year following the later of— (I) the calendar year in which the employee attains the applicable age, or (II) the calendar year in which the employee retires. (ii) Subclause (II) of clause (i) shall not apply— (I) except as provided in section 409(d), in the case of an employee who is a 5-percent owner (as defined in section 416) with respect to the plan year ending in the calendar year in which the employee attains the applicable age, or (II) for purposes of section 408(a)(6) or (b)(3). (iii) In the case of an employee to whom clause (i)(II) applies who retires in a calendar year after the calendar year in which the employee attains age 70½, the employee’s accrued benefit shall be actuarially increased to take into account the period after age 70½ in which the employee was not receiving any benefits under the plan. (iv) Clauses (ii) and (iii) shall not apply in the case of a governmental plan or church plan. For purposes of this clause, the term “church plan” means a plan maintained by a church for church employees, and the term “church” means any church (as defined in section 3121(w)(3)(A)) or qualified church-controlled organization (as defined in section 3121(w)(3)(B)). (I) In the case of an individual who attains age 72 after December 31, 2022, and age 73 before January 1, 2033, the applicable age is 73. (II) In the case of an individual who attains age 74 after December 31, 2032, the applicable age is 75. (D) For purposes of this paragraph, the life expectancy of an employee and the employee’s spouse (other than in the case of a life annuity) may be redetermined but not more frequently than annually. (E) For purposes of this paragraph— (i) The term “designated beneficiary” means any individual designated as a beneficiary by the employee. (ii) The term “eligible designated beneficiary” means, with respect to any employee, any designated beneficiary who is— (I) the surviving spouse of the employee, (II) subject to clause (iii), a child of the employee who has not reached majority (within the meaning of subparagraph (F)), (III) disabled (within the meaning of section 72(m)(7)), (IV) a chronically ill individual (within the meaning of section 7702B(c)(2), except that the requirements of subparagraph (A)(i) thereof shall only be treated as met if there is a certification that, as of such date, the period of inability described in such subparagraph with respect to the individual is an indefinite one which is reasonably expected to be lengthy in nature), or (V) an individual not described in any of the preceding subclauses who is not more than 10 years younger than the employee. (iii) Subject to subparagraph (F), an individual described in clause (ii)(II) shall cease to be an eligible designated beneficiary as of the date the individual reaches majority and any remainder of the portion of the individual’s interest to which subparagraph (H)(ii) applies shall be distributed within 10 years after such date. (F) Under regulations prescribed by the Secretary, for purposes of this paragraph, any amount paid to a child shall be treated as if it had been paid to the surviving spouse if such amount will become payable to the surviving spouse upon such child reaching majority (or other designated event permitted under regulations). (G) For purposes of this title, any distribution required under the incidental death benefit requirements of this subsection shall be treated as a distribution required under this paragraph. (H) In the case of a defined contribution plan, if an employee dies before the distribution of the employee’s entire interest— (i) Except in the case of a beneficiary who is not a designated beneficiary, subparagraph (B)(ii)— (I) shall be applied by substituting “10 years” for “5 years”, and (II) shall apply whether or not distributions of the employee’s interests have begun in accordance with subparagraph (A). (ii) Subparagraph (B)(iii) shall apply only in the case of an eligible designated beneficiary. (iii) If an eligible designated beneficiary dies before the portion of the employee’s interest to which this subparagraph applies is entirely distributed, the exception under clause (ii) shall not apply to any beneficiary of such eligible designated beneficiary and the remainder of such portion shall be distributed within 10 years after the death of such eligible designated beneficiary. (iv) In the case of an applicable multi-beneficiary trust, if under the terms of the trust— (I) it is to be divided immediately upon the death of the employee into separate trusts for each beneficiary, or (II) eligible designated beneficiary described in subclause (III) or (IV) of subparagraph (E)(ii)) has any right to the employee’s interest in the plan until the death of all such eligible designated beneficiaries with respect to the trust, (v) For purposes of this subparagraph, the term “applicable multi-beneficiary trust” means a trust— (I) which has more than one beneficiary, (II) all of the beneficiaries of which are treated as designated beneficiaries for purposes of determining the distribution period pursuant to this paragraph, and (III) at least one of the beneficiaries of which is an eligible designated beneficiary described in subclause (III) or (IV) of subparagraph (E)(ii). (vi) For purposes of applying the provisions of this subparagraph in determining amounts required to be distributed pursuant to this paragraph, all eligible retirement plans (as defined in section 402(c)(8)(B), other than a defined benefit plan described in clause (iv) or (v) thereof or a qualified trust which is a part of a defined benefit plan) shall be treated as a defined contribution plan. (i) The requirements of this paragraph shall not apply for calendar year 2020 to— (I) a defined contribution plan which is described in this subsection or in section 403(a) or 403(b), (II) a defined contribution plan which is an eligible deferred compensation plan described in section 457(b) but only if such plan is maintained by an employer described in section 457(e)(1)(A), or (III) an individual retirement plan. (ii) Clause (i) shall apply to any distribution which is required to be made in calendar year 2020 by reason of— (I) a required beginning date occurring in such calendar year, and (II) such distribution not having been made before January 1, 2020. (iii) For purposes of this paragraph— (I) the required beginning date with respect to any individual shall be determined without regard to this subparagraph for purposes of applying this paragraph for calendar years after 2020, and (II) if clause (ii) of subparagraph (B) applies, the 5-year period described in such clause shall be determined without regard to calendar year 2020. (J) Nothing in this section shall prohibit a commercial annuity (within the meaning of section 3405(e)(6)) that is issued in connection with any eligible retirement plan (within the meaning of section 402(c)(8)(B), other than a defined benefit plan) from providing one or more of the following types of payments on or after the annuity starting date: (i) annuity payments that increase by a constant percentage, applied not less frequently than annually, at a rate that is less than 5 percent per year, (ii) a lump sum payment that— (I) results in a shortening of the payment period with respect to an annuity or a full or partial commutation of the future annuity payments, provided that such lump sum is determined using reasonable actuarial methods and assumptions, as determined in good faith by the issuer of the contract, or (II) accelerates the receipt of annuity payments that are scheduled to be received within the ensuing 12 months, regardless of whether such acceleration shortens the payment period with respect to the annuity, reduces the dollar amount of benefits to be paid under the contract, or results in a suspension of annuity payments during the period being accelerated, (iii) an amount which is in the nature of a dividend or similar distribution, provided that the issuer of the contract determines such amount using reasonable actuarial methods and assumptions, as determined in good faith by the issuer of the contract, when calculating the initial annuity payments and the issuer’s experience with respect to those factors, or (iv) a final payment upon death that does not exceed the excess of the total amount of the consideration paid for the annuity payments, less the aggregate amount of prior distributions or payments from or under the contract. (A) In the case of any plan which provides contributions or benefits for employees some or all of whom are owner-employees (as defined in subsection (c)(3)), a trust forming part of such plan shall constitute a qualified trust under this section only if the requirements of subsection (d) are also met. (i) In the case of any top-heavy plan, a trust forming part of such plan shall constitute a qualified trust under this section only if the requirements of section 416 are met. (ii) Except to the extent provided in regulations, a trust forming part of a plan (whether or not a top-heavy plan) shall constitute a qualified trust under this section only if such plan contains provisions— (I) which will take effect if such plan becomes a top-heavy plan, and (II) which meet the requirements of section 416. (iii) This subparagraph shall not apply to any governmental plan. (A) In the case of any plan to which this paragraph applies, except as provided in section 417, a trust forming part of such plan shall not constitute a qualified trust under this section unless— (i) in the case of a vested participant who does not die before the annuity starting date, the accrued benefit payable to such participant is provided in the form of a qualified joint and survivor annuity, and (ii) in the case of a vested participant who dies before the annuity starting date and who has a surviving spouse, a qualified preretirement survivor annuity is provided to the surviving spouse of such participant. (B) This paragraph shall apply to— (i) any defined benefit plan, (ii) any defined contribution plan which is subject to the funding standards of section 412, and (iii) any participant under any other defined contribution plan unless— (I) such plan provides that the participant’s nonforfeitable accrued benefit (reduced by any security interest held by the plan by reason of a loan outstanding to such participant) is payable in full, on the death of the participant, to the participant’s surviving spouse (or, if there is no surviving spouse or the surviving spouse consents in the manner required under section 417(a)(2), to a designated beneficiary), (II) such participant does not elect a payment of benefits in the form of a life annuity, and (III) with respect to such participant, such plan is not a direct or indirect transferee (in a transfer after December 31, 1984) of a plan which is described in clause (i) or (ii) or to which this clause applied with respect to the participant. (i) In the case of— (I) a tax credit employee stock ownership plan (as defined in section 409(a)), or (II) an employee stock ownership plan (as defined in section 4975(e)(7)), (ii) In the case of any participant, clause (i) shall apply only if the requirements of subclauses (I), (II), and (III) of subparagraph (B)(iii) are met with respect to such participant. (D) A plan shall not be treated as failing to meet the requirements of subparagraphs (B)(iii) or (C) merely because the plan provides that benefits will not be payable to the surviving spouse of the participant unless the participant and such spouse had been married throughout the 1-year period ending on the earlier of the participant’s annuity starting date or the date of the participant’s death. (E) This paragraph shall not apply to a plan which the Secretary has determined is a plan described in section 404(c) (or a continuation thereof) in which participation is substantially limited to individuals who, before January 1, 1976, ceased employment covered by the plan. (F) For— (i) provisions under which participants may elect to waive the requirements of this paragraph, and (ii) other definitions and special rules for purposes of this paragraph, (12) A trust shall not constitute a qualified trust under this section unless the plan of which such trust is a part provides that in the case of any merger or consolidation with, or transfer of assets or liabilities to, any other plan after September 2, 1974, each participant in the plan would (if the plan then terminated) receive a benefit immediately after the merger, consolidation, or transfer which is equal to or greater than the benefit he would have been entitled to receive immediately before the merger, consolidation, or transfer (if the plan had then terminated). The preceding sentence does not apply to any multiemployer plan with respect to any transaction to the extent that participants either before or after the transaction are covered under a multiemployer plan to which title IV of the Employee Retirement Income Security Act of 1974 applies. (A) A trust shall not constitute a qualified trust under this section unless the plan of which such trust is a part provides that benefits provided under the plan may not be assigned or alienated. For purposes of the preceding sentence, there shall not be taken into account any voluntary and revocable assignment of not to exceed 10 percent of any benefit payment made by any participant who is receiving benefits under the plan unless the assignment or alienation is made for purposes of defraying plan administration costs. For purposes of this paragraph a loan made to a participant or beneficiary shall not be treated as an assignment or alienation if such loan is secured by the participant’s accrued nonforfeitable benefit and is exempt from the tax imposed by section 4975 (relating to tax on prohibited transactions) by reason of section 4975(d)(1). This paragraph shall take effect on January 1, 1976 and shall not apply to assignments which were irrevocable on September 2, 1974. (B) Subparagraph (A) shall apply to the creation, assignment, or recognition of a right to any benefit payable with respect to a participant pursuant to a domestic relations order, except that subparagraph (A) shall not apply if the order is determined to be a qualified domestic relations order. (C) Subparagraph (A) shall not apply to any offset of a participant’s benefits provided under a plan against an amount that the participant is ordered or required to pay to the plan if— (i) the order or requirement to pay arises— (I) under a judgment of conviction for a crime involving such plan, (II) under a civil judgment (including a consent order or decree) entered by a court in an action brought in connection with a violation (or alleged violation) of part 4 of subtitle B of title I of the Employee Retirement Income Security Act of 1974, or (III) pursuant to a settlement agreement between the Secretary of Labor and the participant, or a settlement agreement between the Pension Benefit Guaranty Corporation and the participant, in connection with a violation (or alleged violation) of part 4 of such subtitle by a fiduciary or any other person, (ii) the judgment, order, decree, or settlement agreement expressly provides for the offset of all or part of the amount ordered or required to be paid to the plan against the participant’s benefits provided under the plan, and (iii) in a case in which the survivor annuity requirements of section 401(a)(11) apply with respect to distributions from the plan to the participant, if the participant has a spouse at the time at which the offset is to be made— (I) either such spouse has consented in writing to such offset and such consent is witnessed by a notary public or representative of the plan (or it is established to the satisfaction of a plan representative that such consent may not be obtained by reason of circumstances described in section 417(a)(2)(B)), or an election to waive the right of the spouse to either a qualified joint and survivor annuity or a qualified preretirement survivor annuity is in effect in accordance with the requirements of section 417(a), (II) such spouse is ordered or required in such judgment, order, decree, or settlement to pay an amount to the plan in connection with a violation of part 4 of such subtitle, or (III) in such judgment, order, decree, or settlement, such spouse retains the right to receive the survivor annuity under a qualified joint and survivor annuity provided pursuant to section 401(a)(11)(A)(i) and under a qualified preretirement survivor annuity provided pursuant to section 401(a)(11)(A)(ii), determined in accordance with subparagraph (D). (i) The survivor annuity described in subparagraph (C)(iii)(III) shall be determined as if— (I) the participant terminated employment on the date of the offset, (II) there was no offset, (III) the plan permitted commencement of benefits only on or after normal retirement age, (IV) the plan provided only the minimum-required qualified joint and survivor annuity, and (V) the amount of the qualified preretirement survivor annuity under the plan is equal to the amount of the survivor annuity payable under the minimum-required qualified joint and survivor annuity. (ii) For purposes of this subparagraph, the term “minimum-required qualified joint and survivor annuity” means the qualified joint and survivor annuity which is the actuarial equivalent of the participant’s accrued benefit (within the meaning of section 411(a)(7)) and under which the survivor annuity is 50 percent of the amount of the annuity which is payable during the joint lives of the participant and the spouse. (14) A trust shall not constitute a qualified trust under this section unless the plan of which such trust is a part provides that, unless the participant otherwise elects, the payment of benefits under the plan to the participant will begin not later than the 60th day after the latest of the close of the plan year in which— (A) the date on which the participant attains the earlier of age 65 or the normal retirement age specified under the plan, (B) occurs the 10th anniversary of the year in which the participant commenced participation in the plan, or (C) the participant terminates his service with the employer. (15) A trust shall not constitute a qualified trust under this section unless under the plan of which such trust is a part— (A) in the case of a participant or beneficiary who is receiving benefits under such plan, or (B) in the case of a participant who is separated from the service and who has nonforfeitable rights to benefits, (16) A trust shall not constitute a qualified trust under this section if the plan of which such trust is a part provides for benefits or contributions which exceed the limitations of section 415. (A) A trust shall not constitute a qualified trust under this section unless, under the plan of which such trust is a part, the annual compensation of each employee taken into account under the plan for any year does not exceed $200,000. (B) The Secretary shall adjust annually the $200,000 amount in subparagraph (A) for increases in the cost-of-living at the same time and in the same manner as adjustments under section 415(d); except that the base period shall be the calendar quarter beginning July 1, 2001, and any increase which is not a multiple of $5,000 shall be rounded to the next lowest multiple of $5,000. Repealed. Pub. L. 97–248, title II, § 237(b), Sept. 3, 1982, 96 Stat. 511.] (19) A trust shall not constitute a qualified trust under this section if under the plan of which such trust is a part any part of a participant’s accrued benefit derived from employer contributions (whether or not otherwise nonforfeitable), is forfeitable solely because of withdrawal by such participant of any amount attributable to the benefit derived from contributions made by such participant. The preceding sentence shall not apply to the accrued benefit of any participant unless, at the time of such withdrawal, such participant has a nonforfeitable right to at least 50 percent of such accrued benefit (as determined under section 411). The first sentence of this paragraph shall not apply to the extent that an accrued benefit is permitted to be forfeited in accordance with section 411(a)(3)(D)(iii) (relating to proportional forfeitures of benefits accrued before September 2, 1974, in the event of withdrawal of certain mandatory contributions). (20) A trust forming part of a pension plan shall not be treated as failing to constitute a qualified trust under this section merely because the pension plan of which such trust is a part makes 1 or more distributions within 1 taxable year to a distributee on account of a termination of the plan of which the trust is a part, or in the case of a profit-sharing or stock bonus plan, a complete discontinuance of contributions under such plan. This paragraph shall not apply to a defined benefit plan unless the employer maintaining such plan files a notice with the Pension Benefit Guaranty Corporation (at the time and in the manner prescribed by the Pension Benefit Guaranty Corporation) notifying the Corporation of such payment or distribution and the Corporation has approved such payment or distribution or, within 90 days after the date on which such notice was filed, has failed to disapprove such payment or distribution. For purposes of this paragraph, rules similar to the rules of section 402(a)(6)(B) (as in effect before its repeal by section 521 of the Unemployment Compensation Amendments of 1992) shall apply. Repealed. Pub. L. 99–514, title XI, § 1171(b)(5), Oct. 22, 1986, 100 Stat. 2513.] (22) If a defined contribution plan (other than a profit-sharing plan)— (A) is established by an employer whose stock is not readily tradable on an established market, and (B) after acquiring securities of the employer, more than 10 percent of the total assets of the plan are securities of the employer, (23) A stock bonus plan shall not be treated as meeting the requirements of this section unless such plan meets the requirements of subsections (h) and (o) of section 409, except that in applying section 409(h) for purposes of this paragraph, the term “employer securities” shall include any securities of the employer held by the plan. (24) Any group trust which otherwise meets the requirements of this section shall not be treated as not meeting such requirements on account of the participation or inclusion in such trust of the moneys of any plan or governmental unit described in section 818(a)(6). (25) A defined benefit plan shall not be treated as providing definitely determinable benefits unless, whenever the amount of any benefit is to be determined on the basis of actuarial assumptions, such assumptions are specified in the plan in a way which precludes employer discretion. (A) In the case of a trust which is a part of a defined benefit plan, such trust shall not constitute a qualified trust under this subsection unless on each day of the plan year such trust benefits at least the lesser of— (i) 50 employees of the employer, or (ii) the greater of— (I) 40 percent of all employees of the employer, or (II) 2 employees (or if there is only 1 employee, such employee). (i) A plan may exclude from consideration under this paragraph employees described in paragraphs (3) and (4)(A) of section 410(b). (ii) If employees described in section 410(b)(4)(B) are covered under a plan which meets the requirements of subparagraph (A) separately with respect to such employees, such employees may be excluded from consideration in determining whether any plan of the employer meets such requirements if— (I) the benefits for such employees are provided under the same plan as benefits for other employees, (II) the benefits provided to such employees are not greater than comparable benefits provided to other employees under the plan, and (III) no highly compensated employee (within the meaning of section 414(q)) is included in the group of such employees for more than 1 year. (C) Except to the extent provided in regulations, a plan covering only employees described in section 410(b)(3)(A) may exclude from consideration any employees who are not included in the unit or units in which the covered employees are included. (D) Except to the extent provided in regulations, this paragraph shall not apply to employees in a multiemployer plan (within the meaning of section 414(f)) who are covered by collective bargaining agreements. (E) Rules similar to the rules of section 410(b)(6)(C) shall apply for purposes of this paragraph. (F) At the election of the employer and with the consent of the Secretary, this paragraph may be applied separately with respect to each separate line of business of the employer. For purposes of this paragraph, the term “separate line of business” has the meaning given such term by section 414(r) (without regard to paragraph (2)(A) or (7) thereof). (G) This paragraph shall not apply to a governmental plan (within the meaning of section 414(d)). (H) The Secretary may by regulation provide that any separate benefit structure, any separate trust, or any other separate arrangement is to be treated as a separate plan for purposes of applying this paragraph. (i) A plan shall be deemed to satisfy the requirements of subparagraph (A) if— (I) the plan is amended— (aa) to cease all benefit accruals, or (bb) to provide future benefit accruals only to a closed class of participants, (II) the plan satisfies subparagraph (A) (without regard to this subparagraph) as of the effective date of the amendment, and (III) the amendment was adopted before April 5, 2017, or the plan is described in clause (ii). (ii) A plan is described in this clause if the plan would be described in subsection (o)(1)(C), as applied for purposes of subsection (o)(1)(B)(iii)(IV) and by treating the effective date of the amendment as the date the class was closed for purposes of subsection (o)(1)(C). (iii) For purposes of clause (i)(II), in applying section 410(b)(6)(C), the amendments described in clause (i) shall not be treated as a significant change in coverage under section 410(b)(6)(C)(i)(II). (iv) For purposes of this subparagraph, if a portion of a plan described in clause (i) is spun off to another employer, the treatment under clause (i) of the spun-off plan shall continue with respect to the other employer. (A) The determination of whether the plan under which any contributions are made is a profit-sharing plan shall be made without regard to current or accumulated profits of the employer and without regard to whether the employer is a tax-exempt organization. (B) In the case of a plan which is intended to be a money purchase pension plan or a profit-sharing plan, a trust forming part of such plan shall not constitute a qualified trust under this subsection unless the plan designates such intent at such time and in such manner as the Secretary may prescribe. (A) In the case of a trust which is part of an employee stock ownership plan (within the meaning of section 4975(e)(7)) or a plan which meets the requirements of section 409(a), such trust shall not constitute a qualified trust under this section unless such plan meets the requirements of subparagraphs (B) and (C).

(G) A governmental plan (within the meaning of section 414(d)) shall be treated as meeting the requirements of this paragraph. (A) A cash or deferred arrangement of any employer shall not be treated as a qualified cash or deferred arrangement if any other benefit (other than a de minimis financial incentive (not paid for with plan assets) provided to employees who elect to have the employer make contributions under the arrangement in lieu of receiving cash) is conditioned (directly or indirectly) on the employee electing to have the employer make or not make contributions under the arrangement in lieu of receiving cash. The preceding sentence shall not apply to any matching contribution (as defined in section 401(m)) made by reason of such an election.

(C) A rural cooperative plan which includes a qualified cash or deferred arrangement shall not be treated as violating the requirements of section 401(a) or of paragraph (2) merely by reason of a hardship distribution or a distribution to a participant after attainment of age 59½. For purposes of this section, the term “hardship distribution” means a distribution described in paragraph (2)(B)(i)(IV) (without regard to the limitation of its application to profit-sharing or stock bonus plans). (A) A cash or deferred arrangement shall not be treated as failing to meet the requirements of clause (ii) of paragraph (3)(A) for any plan year if, before the close of the following plan year— (i) the amount of the excess contributions for such plan year (and any income allocable to such contributions through the end of such year) is distributed, or (ii) to the extent provided in regulations, the employee elects to treat the amount of the excess contributions as an amount distributed to the employee and then contributed by the employee to the plan.

(D) No tax shall be imposed under section 72(t) on any amount required to be distributed under this paragraph. (E) For purposes of paragraph (2)(C), a matching contribution (within the meaning of subsection (m)) shall not be treated as forfeitable merely because such contribution is forfeitable if the contribution to which the matching contribution relates is treated as an excess contribution under subparagraph (B), an excess deferral under section 402(g)(2)(A), a permissible withdrawal under section 414(w), or an excess aggregate contribution under section 401(m)(6)(B).

If an employer makes an election under this subparagraph for any year, the employer shall notify employees of such election within a reasonable period of time before the 60th day before the beginning of such year.

(C) The requirements of this subparagraph are met for any year to which this paragraph applies if no contributions were made, or benefits were accrued, for services during such year under any qualified plan of the employer on behalf of any employee eligible to participate in the cash or deferred arrangement, other than contributions described in subparagraph (B). (i) For purposes of this paragraph, any term used in this paragraph which is also used in section 408(p) shall have the meaning given such term by such section. (ii) A plan meeting the requirements of this paragraph for any year shall not be treated as a top-heavy plan under section 416 for such year if such plan allows only contributions required under this paragraph. (E) In the case of an employer which applies an election under section 408(p)(2)(E)(i)(II) for purposes of the contribution requirements of this paragraph under subparagraph (B)(i)(I), rules similar to the rules of subparagraphs (B)(iii), (C)(ii)(IV), and (G) of section 408(p)(2) shall apply for purposes of subparagraphs (B)(i)(II) and (B)(ii) of this paragraph.

(i) The requirements of this subparagraph are met if, under the arrangement, the employer makes matching contributions on behalf of each employee who is not a highly compensated employee in an amount equal to— (I) 100 percent of the elective contributions of the employee to the extent such elective contributions do not exceed 3 percent of the employee’s compensation, and (II) 50 percent of the elective contributions of the employee to the extent that such elective contributions exceed 3 percent but do not exceed 5 percent of the employee’s compensation. (ii) The requirements of this subparagraph are not met if, under the arrangement, the rate of matching contribution with respect to any elective contribution of a highly compensated employee at any rate of elective contribution is greater than that with respect to an employee who is not a highly compensated employee. (iii) If the rate of any matching contribution with respect to any rate of elective contribution is not equal to the percentage required under clause (i), an arrangement shall not be treated as failing to meet the requirements of clause (i) if— (I) the rate of an employer’s matching contribution does not increase as an employee’s rate of elective contributions increase, and (II) the aggregate amount of matching contributions at such rate of elective contribution is at least equal to the aggregate amount of matching contributions which would be made if matching contributions were made on the basis of the percentages described in clause (i). (C) The requirements of this subparagraph are met if, under the arrangement, the employer is required, without regard to whether the employee makes an elective contribution or employee contribution, to make a contribution to a defined contribution plan on behalf of each employee who is not a highly compensated employee and who is eligible to participate in the arrangement in an amount equal to at least 3 percent of the employee’s compensation. (D) An arrangement meets the requirements of this paragraph if, under the arrangement, each employee eligible to participate is, within a reasonable period before any year, given written notice of the employee’s rights and obligations under the arrangement which— (i) is sufficiently accurate and comprehensive to apprise the employee of such rights and obligations, and (ii) is written in a manner calculated to be understood by the average employee eligible to participate. (i) An arrangement shall not be treated as meeting the requirements of subparagraph (B) or (C) of this paragraph unless the requirements of subparagraphs (B) and (C) of paragraph (2) are met with respect to all employer contributions (including matching contributions) taken into account in determining whether the requirements of subparagraphs (B) and (C) of this paragraph are met. (ii) An arrangement shall not be treated as meeting the requirements of subparagraph (B) or (C) unless such requirements are met without regard to subsection (l), and, for purposes of subsection (l), employer contributions under subparagraph (B) or (C) shall not be taken into account. (i) Except as provided in clause (ii), a plan may be amended after the beginning of a plan year to provide that the requirements of subparagraph (C) shall apply to the arrangement for the plan year, but only if the amendment is adopted— (I) at any time before the 30th day before the close of the plan year, or (II) at any time before the last day under paragraph (8)(A) for distributing excess contributions for the plan year. (ii) Clause (i) shall not apply to any plan year if the plan provided at any time during the plan year that the requirements of subparagraph (B) or paragraph (13)(D)(i)(I) applied to the plan year. (iii) Clause (i)(II) shall not apply to an arrangement unless the amount of the contributions described in subparagraph (C) which the employer is required to make under the arrangement for the plan year with respect to any employee is an amount equal to at least 4 percent of the employee’s compensation. (G) An arrangement shall be treated as meeting the contribution requirements under subparagraph (B) or (C) if any other plan maintained by the employer meets such requirements with respect to employees eligible under the arrangement.

(B) For purposes of this paragraph, the term “qualified automatic contribution arrangement” means a cash or deferred arrangement— (i) which is described in subparagraph (D)(i)(I) and meets the applicable requirements of subparagraphs (C) through (E), or (ii) which is described in subparagraph (D)(i)(II) and meets the applicable requirements of subparagraphs (C) and (D). (i) The requirements of this subparagraph are met if, under the arrangement, each employee eligible to participate in the arrangement is treated as having elected to have the employer make elective contributions in an amount equal to a qualified percentage of compensation. (ii) The election treated as having been made under clause (i) shall cease to apply with respect to any employee if such employee makes an affirmative election— (I) to not have such contributions made, or (II) to make elective contributions at a level specified in such affirmative election. (iii) For purposes of this subparagraph, the term “qualified percentage” means, with respect to any employee, any percentage determined under the arrangement if such percentage is applied uniformly, does not exceed 15 percent (10 percent during the period described in subclause (I)), and is at least— (I) 3 percent during the period ending on the last day of the first plan year which begins after the date on which the first elective contribution described in clause (i) is made with respect to such employee, (II) 4 percent during the first plan year following the plan year described in subclause (I), (III) 5 percent during the second plan year following the plan year described in subclause (I), and (IV) 6 percent during any subsequent plan year. (iv) Clause (i) may be applied without taking into account any employee who— (I) was eligible to participate in the arrangement (or a predecessor arrangement) immediately before the date on which such arrangement becomes a qualified automatic contribution arrangement (determined after application of this clause), and (II) had an election in effect on such date either to participate in the arrangement or to not participate in the arrangement. (i) The requirements of this subparagraph are met if, under the arrangement, the employer— (I) makes matching contributions on behalf of each employee who is not a highly compensated employee in an amount equal to the sum of 100 percent of the elective contributions of the employee to the extent that such contributions do not exceed 1 percent of compensation plus 50 percent of so much of such contributions as exceed 1 percent but do not exceed 6 percent of compensation, or (II) is required, without regard to whether the employee makes an elective contribution or employee contribution, to make a contribution to a defined contribution plan on behalf of each employee who is not a highly compensated employee and who is eligible to participate in the arrangement in an amount equal to at least 3 percent of the employee’s compensation. (ii) The rules of clauses (ii) and (iii) of paragraph (12)(B) shall apply for purposes of clause (i)(I). (iii) An arrangement shall not be treated as meeting the requirements of clause (i) unless, with respect to employer contributions (including matching contributions) taken into account in determining whether the requirements of clause (i) are met— (I) any employee who has completed at least 2 years of service (within the meaning of section 411(a)) has a nonforfeitable right to 100 percent of the employee’s accrued benefit derived from such employer contributions, and (II) the requirements of subparagraph (B) of paragraph (2) are met with respect to all such employer contributions.

(iv) Earnings on any contributions described in clause (i), (ii), or (iii).

(iii) For purposes of this subparagraph, the term “qualified percentage” means, with respect to any employee, any percentage determined under the arrangement if such percentage is applied uniformly and is not less than 3 or more than 15 percent.

(B) In the case of an offset plan, the plan provides that— (i) a participant’s accrued benefit attributable to employer contributions (within the meaning of section 411(c)(1)) may not be reduced (by reason of the offset) by more than the maximum offset allowance, and (ii) benefits are based on average annual compensation. (4) For purposes of paragraph (3)— (A) The maximum excess allowance is equal to— (i) in the case of benefits attributable to any year of service with the employer taken into account under the plan, ¾ of a percentage point, and (ii) in the case of total benefits, ¾ of a percentage point, multiplied by the participant’s years of service (not in excess of 35) with the employer taken into account under the plan. (B) The maximum offset allowance is equal to— (i) in the case of benefits attributable to any year of service with the employer taken into account under the plan, ¾ percent of the participant’s final average compensation, and (ii) in the case of total benefits, ¾ percent of the participant’s final average compensation, multiplied by the participant’s years of service (not in excess of 35) with the employer taken into account under the plan.

(D) The term “offset plan” means any plan with respect to which the benefit attributable to employer contributions for each participant is reduced by an amount specified in the plan. (5) For purposes of this subsection— (i) The term “integration level” means the amount of compensation specified under the plan (by dollar amount or formula) at or below which the rate at which contributions or benefits are provided (expressed as a percentage) is less than such rate above such amount. (ii) The integration level for any year may not exceed the contribution and benefit base in effect under section 230 of the Social Security Act for such year. (iii) A plan’s integration level shall apply with respect to all participants in the plan.

(i) The term “covered compensation” means, with respect to an employee, the average of the contribution and benefit bases in effect under section 230 of the Social Security Act for each year in the 35-year period ending with the year in which the employee attains the social security retirement age. (ii) For purposes of clause (i), the determination for any year preceding the year in which the employee attains the social security retirement age shall be made by assuming that there is no increase in the bases described in clause (i) after the determination year and before the employee attains the social security retirement age. (iii) For purposes of this subparagraph, the term “social security retirement age” has the meaning given such term by section 415(b)(8). (F) The Secretary shall prescribe such regulations as are necessary or appropriate to carry out the purposes of this subsection, including— (i) in the case of a defined benefit plan which provides for unreduced benefits commencing before the social security retirement age (as defined in section 415(b)(8)), rules providing for the reduction of the maximum excess allowance and the maximum offset allowance, and (ii) in the case of an employee covered by 2 or more plans of the employer which fail to meet the requirements of subsection (a)(4) (without regard to this subsection), rules preventing the multiple use of the disparity permitted under this subsection with respect to any employee. (6) In determining whether a plan which includes employees of a railroad employer who are entitled to benefits under the Railroad Retirement Act of 1974 meets the requirements of this subsection, rules similar to the rules set forth in this subsection shall apply. Such rules shall take into account the employer-derived portion of the employees’ tier 2 railroad retirement benefits and any supplemental annuity under the Railroad Retirement Act of 1974. (1) A defined contribution plan shall be treated as meeting the requirements of subsection (a)(4) with respect to the amount of any matching contribution or employee contribution for any plan year only if the contribution percentage requirement of paragraph (2) of this subsection is met for such plan year. (A) A plan meets the contribution percentage requirement of this paragraph for any plan year only if the contribution percentage for eligible highly compensated employees for such plan year does not exceed the greater of— (i) 125 percent of such percentage for all other eligible employees for the preceding plan year, or (ii) the lesser of 200 percent of such percentage for all other eligible employees for the preceding plan year, or such percentage for all other eligible employees for the preceding plan year plus 2 percentage points. (B) If two or more plans of an employer to which matching contributions, employee contributions, or elective deferrals are made are treated as one plan for purposes of section 410(b), such plans shall be treated as one plan for purposes of this subsection. If a highly compensated employee participates in two or more plans of an employer to which contributions to which this subsection applies are made, all such contributions shall be aggregated for purposes of this subsection. (3) For purposes of paragraph (2), the contribution percentage for a specified group of employees for a plan year shall be the average of the ratios (calculated separately for each employee in such group) of— (A) the sum of the matching contributions and employee contributions paid under the plan on behalf of each such employee for such plan year, to (B) the employee’s compensation (within the meaning of section 414(s)) for such plan year. (4) For purposes of this subsection— (A) The term “matching contribution” means— (i) any employer contribution made to a defined contribution plan on behalf of an employee on account of an employee contribution made by such employee, (ii) any employer contribution made to a defined contribution plan on behalf of an employee on account of an employee’s elective deferral, and (iii) subject to the requirements of paragraph (14), any employer contribution made to a defined contribution plan on behalf of an employee on account of a qualified student loan payment. (B) The term “elective deferral” means any employer contribution described in section 402(g)(3). (C) The term “qualified nonelective contribution” means any employer contribution (other than a matching contribution) with respect to which— (i) the employee may not elect to have the contribution paid to the employee in cash instead of being contributed to the plan, and (ii) the requirements of subparagraphs (B) and (C) of subsection (k)(2) are met. (D) The term “qualified student loan payment” means a payment made by an employee in repayment of a qualified education loan (as defined in section 221(d)(1)) incurred by the employee to pay qualified higher education expenses, but only— (i) to the extent such payments in the aggregate for the year do not exceed an amount equal to— (I) the limitation applicable under section 402(g) for the year (or, if lesser, the employee’s compensation (as defined in section 415(c)(3)) for the year), reduced by (II) the elective deferrals made by the employee for such year, and (ii) if the employee certifies annually to the employer making the matching contribution under this paragraph that such payment has been made on such loan. (A) Any employee who is eligible to make an employee contribution (or, if the employer takes elective contributions into account, elective contributions) or to receive a matching contribution under the plan being tested under paragraph (1) shall be considered an eligible employee for purposes of this subsection. (B) If an employee contribution is required as a condition of participation in the plan, any employee who would be a participant in the plan if such employee made such a contribution shall be treated as an eligible employee on behalf of whom no employer contributions are made. (C) If an employer elects to apply section 410(b)(4)(B) in determining whether a plan meets the requirements of section 410(b), the employer may, in determining whether the plan meets the requirements of paragraph (2), exclude from consideration all eligible employees (other than highly compensated employees) who have not met the minimum age and service requirements of section 410(a)(1)(A). (A) A plan shall not be treated as failing to meet the requirements of paragraph (1) for any plan year if, before the close of the following plan year, the amount of the excess aggregate contributions for such plan year (and any income allocable to such contributions through the end of such year) is distributed (or, if forfeitable, is forfeited). Such contributions (and such income) may be distributed without regard to any other provision of law. (B) For purposes of subparagraph (A), the term “excess aggregate contributions” means, with respect to any plan year, the excess of— (i) the aggregate amount of the matching contributions and employee contributions (and any qualified nonelective contribution or elective contribution taken into account in computing the contribution percentage) actually made on behalf of highly compensated employees for such plan year, over (ii) the maximum amount of such contributions permitted under the limitations of paragraph (2)(A) (determined by reducing contributions made on behalf of highly compensated employees in order of their contribution percentages beginning with the highest of such percentages). (C) Any distribution of the excess aggregate contributions for any plan year shall be made to highly compensated employees on the basis of the amount of contributions on behalf of, or by, each such employee. Forfeitures of excess aggregate contributions may not be allocated to participants whose contributions are reduced under this paragraph. (D) The determination of the amount of excess aggregate contributions with respect to a plan shall be made after— (i) first determining the excess deferrals (within the meaning of section 402(g)), and (ii) then determining the excess contributions under subsection (k). (A) No tax shall be imposed under section 72(t) on any amount required to be distributed under paragraph (6). (B) Any distribution attributable to employee contributions shall not be included in gross income except to the extent attributable to income on such contributions. (8) For purposes of this subsection, the term “highly compensated employee” has the meaning given to such term by section 414(q). (9) The Secretary shall prescribe such regulations as may be necessary to carry out the purposes of this subsection and subsection (k), including regulations permitting appropriate aggregation of plans and contributions. (10) A defined contribution plan shall be treated as meeting the requirements of paragraph (2) with respect to matching contributions if the plan— (A) meets the contribution requirements of subparagraph (B) of subsection (k)(11), (B) meets the exclusive plan requirements of subsection (k)(11)(C), and (C) meets the vesting requirements of section 408(p)(3). (A) A defined contribution plan shall be treated as meeting the requirements of paragraph (2) with respect to matching contributions if the plan— (i) meets the contribution requirements of subparagraph (B) or (C) of subsection (k)(12), (ii) meets the notice requirements of subsection (k)(12)(D), and (iii) meets the requirements of subparagraph (B). (B) The requirements of this subparagraph are met if— (i) matching contributions on behalf of any employee may not be made with respect to an employee’s contributions or elective deferrals in excess of 6 percent of the employee’s compensation, (ii) the rate of an employer’s matching contribution does not increase as the rate of an employee’s contributions or elective deferrals increase, and (iii) the matching contribution with respect to any highly compensated employee at any rate of an employee contribution or rate of elective deferral is not greater than that with respect to an employee who is not a highly compensated employee. (12) A defined contribution plan shall be treated as meeting the requirements of paragraph (2) with respect to matching contributions if the plan— (A) is a qualified automatic contribution arrangement (as defined in subsection (k)(13)), (B) meets the notice requirements of subsection (k)(13)(E), and (C) meets the requirements of paragraph (11)(B). (A) For purposes of paragraph (4)(A)(iii), an employer contribution made to a defined contribution plan on account of a qualified student loan payment shall be treated as a matching contribution for purposes of this title if— (i) the plan provides matching contributions on account of elective deferrals at the same rate as contributions on account of qualified student loan payments, (ii) the plan provides matching contributions on account of qualified student loan payments only on behalf of employees otherwise eligible to receive matching contributions on account of elective deferrals, (iii) under the plan, all employees eligible to receive matching contributions on account of elective deferrals are eligible to receive matching contributions on account of qualified student loan payments, and (iv) the plan provides that matching contributions on account of qualified student loan payments vest in the same manner as matching contributions on account of elective deferrals. (i) For purposes of subparagraph (A)(iii), subsection (a)(4), and section 410(b), matching contributions described in paragraph (4)(A)(iii) shall not fail to be treated as available to an employee solely because such employee does not have debt incurred under a qualified education loan (as defined in section 221(d)(1)). (ii) Except as provided in clause (iii), a qualified student loan payment shall not be treated as a contribution to a plan under this title. (iii) Solely for purposes of meeting the requirements of paragraph (11)(B), (12), or (13) of this subsection, or paragraph (11)(B)(i)(II), (12)(B), (13)(D), or (16)(D) of subsection (k), a plan may treat a qualified student loan payment as an elective deferral or an elective contribution, whichever is applicable. (iv) In determining whether a plan meets the requirements of subsection (k)(3)(A)(ii) for a plan year, the plan may apply the requirements of such subsection separately with respect to all employees who receive matching contributions described in paragraph (4)(A)(iii) for the plan year. (C) The employer may rely on an employee certification of payment under paragraph (4)(D)(ii). (14) For excise tax on certain excess contributions, see section 4979. (n) The Secretary shall prescribe such rules or regulations as may be necessary to coordinate the requirements of subsection (a)(13)(B) and section 414(p) (and the regulations issued by the Secretary of Labor thereunder) with the other provisions of this chapter. (A) A defined benefit plan which provides benefits, rights, or features to a closed class of participants shall not fail to satisfy the requirements of subsection (a)(4) by reason of the composition of such closed class or the benefits, rights, or features provided to such closed class, if— (i) for the plan year as of which the class closes and the 2 succeeding plan years, such benefits, rights, and features satisfy the requirements of subsection (a)(4) (without regard to this subparagraph but taking into account the rules of subparagraph (I)), (ii) after the date as of which the class was closed, any plan amendment which modifies the closed class or the benefits, rights, and features provided to such closed class does not discriminate significantly in favor of highly compensated employees, and (iii) the class was closed before April 5, 2017, or the plan is described in subparagraph (C). (i) For purposes of determining compliance with subsection (a)(4) and section 410(b), a defined benefit plan described in clause (iii) may be aggregated and tested on a benefits basis with 1 or more defined contribution plans, including with the portion of 1 or more defined contribution plans which— (I) provides matching contributions (as defined in subsection (m)(4)(A)), (II) provides annuity contracts described in section 403(b) which are purchased with matching contributions or nonelective contributions, or (III) consists of an employee stock ownership plan (within the meaning of section 4975(e)(7)) or a tax credit employee stock ownership plan (within the meaning of section 409(a)). (ii) For purposes of clause (i), if a defined benefit plan is aggregated with a portion of a defined contribution plan providing matching contributions— (I) such defined benefit plan must also be aggregated with any portion of such defined contribution plan which provides elective deferrals described in subparagraph (A) or (C) of section 402(g)(3), and (II) such matching contributions shall be treated in the same manner as nonelective contributions, including for purposes of applying the rules of subsection (l). (iii) A defined benefit plan is described in this clause if— (I) the plan provides benefits to a closed class of participants, (II) for the plan year as of which the class closes and the 2 succeeding plan years, the plan satisfies the requirements of section 410(b) and subsection (a)(4) (without regard to this subparagraph but taking into account the rules of subparagraph (I)), (III) after the date as of which the class was closed, any plan amendment which modifies the closed class or the benefits provided to such closed class does not discriminate significantly in favor of highly compensated employees, and (IV) the class was closed before April 5, 2017, or the plan is described in subparagraph (C). (C) A plan is described in this subparagraph if, taking into account any predecessor plan— (i) such plan has been in effect for at least 5 years as of the date the class is closed, and (ii) during the 5-year period preceding the date the class is closed, there has not been a substantial increase in the coverage or value of the benefits, rights, or features described in subparagraph (A) or in the coverage or benefits under the plan described in subparagraph (B)(iii) (whichever is applicable). (D) In applying subparagraph (C)(ii) for purposes of subparagraph (A)(iii), a plan shall be treated as having had a substantial increase in coverage or value of the benefits, rights, or features described in subparagraph (A) during the applicable 5-year period only if, during such period— (i) the number of participants covered by such benefits, rights, or features on the date such period ends is more than 50 percent greater than the number of such participants on the first day of the plan year in which such period began, or (ii) such benefits, rights, and features have been modified by 1 or more plan amendments in such a way that, as of the date the class is closed, the value of such benefits, rights, and features to the closed class as a whole is substantially greater than the value as of the first day of such 5-year period, solely as a result of such amendments. (E) In applying subparagraph (C)(ii) for purposes of subparagraph (B)(iii)(IV), a plan shall be treated as having had a substantial increase in coverage or benefits during the applicable 5-year period only if, during such period— (i) the number of participants benefitting under the plan on the date such period ends is more than 50 percent greater than the number of such participants on the first day of the plan year in which such period began, or (ii) the average benefit provided to such participants on the date such period ends is more than 50 percent greater than the average benefit provided on the first day of the plan year in which such period began. (F) For purposes of subparagraphs (D) and (E), any increase in coverage or value or in coverage or benefits, whichever is applicable, which is attributable to such coverage and value or coverage and benefits provided to employees— (i) who became participants as a result of a merger, acquisition, or similar event which occurred during the 7-year period preceding the date the class is closed, or (ii) who became participants by reason of a merger of the plan with another plan which had been in effect for at least 5 years as of the date of the merger, (G) For purposes of subparagraph (E)— (i) the average benefit provided to participants under the plan will be treated as having remained the same between the 2 dates described in subparagraph (E)(ii) if the benefit formula applicable to such participants has not changed between such dates, and (ii) if the benefit formula applicable to 1 or more participants under the plan has changed between such 2 dates, then the average benefit under the plan shall be considered to have increased by more than 50 percent only if— (I) the total amount determined under section 430(b)(1)(A)(i) for all participants benefitting under the plan for the plan year in which the 5-year period described in subparagraph (E) ends, exceeds (II) the total amount determined under section 430(b)(1)(A)(i) for all such participants for such plan year, by using the benefit formula in effect for each such participant for the first plan year in such 5-year period, (H) For purposes of subparagraphs (E) and (G), a plan described in section 413(c) shall be treated as a single plan rather than as separate plans maintained by each employer in the plan. (I) For purposes of subparagraphs (A)(i) and (B)(iii)(II), the following rules shall apply: (i) In applying section 410(b)(6)(C), the closing of the class of participants shall not be treated as a significant change in coverage under section 410(b)(6)(C)(i)(II). (ii) 2 or more plans shall not fail to be eligible to be aggregated and treated as a single plan solely by reason of having different plan years. (iii) Changes in the employee population shall be disregarded to the extent attributable to individuals who become employees or cease to be employees, after the date the class is closed, by reason of a merger, acquisition, divestiture, or similar event. (iv) Aggregation and all other testing methodologies otherwise applicable under subsection (a)(4) and section 410(b) may be taken into account. (J) For purposes of this paragraph, if a portion of a defined benefit plan described in subparagraph (A) or (B)(iii) is spun off to another employer and the spun-off plan continues to satisfy the requirements of— (i) subparagraph (A)(i) or (B)(iii)(II), whichever is applicable, if the original plan was still within the 3-year period described in such subparagraph at the time of the spin off, and (ii) subparagraph (A)(ii) or (B)(iii)(III), whichever is applicable, (A) A defined contribution plan shall be permitted to be tested on a benefits basis if— (i) such defined contribution plan provides make-whole contributions to a closed class of participants whose accruals under a defined benefit plan have been reduced or eliminated, (ii) for the plan year of the defined contribution plan as of which the class eligible to receive such make-whole contributions closes and the 2 succeeding plan years, such closed class of participants satisfies the requirements of section 410(b)(2)(A)(i) (determined by applying the rules of paragraph (1)(I)), (iii) after the date as of which the class was closed, any plan amendment to the defined contribution plan which modifies the closed class or the allocations, benefits, rights, and features provided to such closed class does not discriminate significantly in favor of highly compensated employees, and (iv) the class was closed before April 5, 2017, or the defined benefit plan under clause (i) is described in paragraph (1)(C) (as applied for purposes of paragraph (1)(B)(iii)(IV)). (i) With respect to 1 or more defined contribution plans described in subparagraph (A), for purposes of determining compliance with subsection (a)(4) and section 410(b), the portion of such plans which provides make-whole contributions or other nonelective contributions may be aggregated and tested on a benefits basis with the portion of 1 or more other defined contribution plans which— (I) provides matching contributions (as defined in subsection (m)(4)(A)), (II) provides annuity contracts described in section 403(b) which are purchased with matching contributions or nonelective contributions, or (III) consists of an employee stock ownership plan (within the meaning of section 4975(e)(7)) or a tax credit employee stock ownership plan (within the meaning of section 409(a)). (ii) Rules similar to the rules of paragraph (1)(B)(ii) shall apply for purposes of clause (i). (C) In the case of a defined contribution plan which provides benefits, rights, or features to a closed class of participants whose accruals under a defined benefit plan have been reduced or eliminated, the plan shall not fail to satisfy the requirements of subsection (a)(4) solely by reason of the composition of the closed class or the benefits, rights, or features provided to such closed class if the defined contribution plan and defined benefit plan otherwise meet the requirements of subparagraph (A) but for the fact that the make-whole contributions under the defined contribution plan are made in whole or in part through matching contributions. (D) For purposes of this paragraph, if a portion of a defined contribution plan described in subparagraph (A) or (C) is spun off to another employer, the treatment under subparagraph (A) or (C) of the spun-off plan shall continue with respect to the other employer if such plan continues to comply with the requirements of clauses (ii) (if the original plan was still within the 3-year period described in such clause at the time of the spin off) and (iii) of subparagraph (A), as determined for purposes of subparagraph (A) or (C), whichever is applicable. (3) For purposes of this subsection— (A) Except as otherwise provided in paragraph (2)(C), the term “make-whole contributions” means nonelective allocations for each employee in the class which are reasonably calculated, in a consistent manner, to replace some or all of the retirement benefits which the employee would have received under the defined benefit plan and any other plan or qualified cash or deferred arrangement under subsection (k)(2) if no change had been made to such defined benefit plan and such other plan or arrangement. For purposes of the preceding sentence, consistency shall not be required with respect to employees who were subject to different benefit formulas under the defined benefit plan. (B) References to a closed class of participants and similar references to a closed class shall include arrangements under which 1 or more classes of participants are closed, except that 1 or more classes of participants closed on different dates shall not be aggregated for purposes of determining the date any such class was closed. (C) The term “highly compensated employee” has the meaning given such term in section 414(q). (p) For exemption from tax of a trust qualified under this section, see section 501(a).
