PART I - M&P PLANS

SECTION 5. PROVISIONS REQUIRED

Internal Revenue Bulletin 2005-10 · 2026-10-03 edition · updated 2026-10-04 · United States

IN EVERY M&P PLAN

.01 Sponsor Amendments - M&P plans must provide a procedure for sponsor amendment, so that changes in the Code, regulations, revenue rulings, other statements published by the Internal Revenue Service, or corrections of prior approved plans may be applied to all employers who have adopted the plan. Sponsors must make reasonable and diligent efforts to ensure that adopting employers of the sponsor’s M&P plan have actually received and are aware of all plan amendments and that such employers complete and sign new adoption agreements when necessary. See section 5.11. Failure to comply with this requirement may result in the loss of eligibility to sponsor M&P plans and the revocation of opinion letters that have been issued to the sponsor.

.02 Employer Amendments — An employer that amends any provision of an approved M&P plan including its adoption agreement (other than to change the choice of options, if the plan permits or contemplates such a change) or an employer that chooses to discontinue participation in a plan as amended by its sponsor and does not substitute another approved M&P plan is considered to have adopted an individually designed plan. However, this rule does not apply in the case of amendments permitted under sections 5.06 and 5.09 and sample or model amendments published by the Service (or other required good faith amendments) that specifically provide that their adoption by an adopter of an M&P plan will not cause such plan to be treated as individually designed. Also see section 19.03 regarding the effect of employer amendments on an employer’s ability to rely on an opinion letter and section 24

with respect to applicable remedial amendment periods. An employer that amends an M&P plan because of a waiver of the minimum funding requirement under § 412(d) will also be considered to have an individually designed plan. The procedures stated in Rev. Proc. 2005–6 relating to the issuance of determination letters for individually designed plans will then apply to the plan as adopted by the employer.

.03 Compensation Requirements in Nonstandardized Plans - Each nonstandardized M&P plan must give the adopting employer the option to select total compensation as the compensation to be used in determining allocations or benefits. For this purpose, total compensation means a definition that includes all compensation within the meaning of § 415(c)(3) and excludes all other compensation or that otherwise satisfies § 414(s) under § 1.414(s)–1(c).

.04 Automatic or Optional Safe Harbor Provisions in Nonstandardized Plans

  • Each nonstandardized M&P plan must automatically or by option allow the adopting employer to satisfy one of the design-based safe harbors described in § 1.401(a)(4)–2(b)(2) or § 1.401(a)(4)–3(b)(3), (4), and (5). A nonstandardized defined contribution plan is permitted to include allocation formulas which must be general tested under § 1.401(a)(4)–2(c) or cross-tested under § 1.401(a)(4)–8. A nonstandardized defined benefit plan is permitted to include benefit formulas that must be general tested under § 1.401(a)(4)–3(c).

.05 Anti-Cutback Provisions - M&P plans must specifically provide for the protection provided under § 411(a)(10) and (d)(6), to the extent required, in the event that the employer amends the plan in any manner such as by revising the options selected in the adoption agreement or by adopting a new M&P plan. An M&P sponsor may not amend its plan in a manner that could result in the elimination of a benefit to the extent the benefit is required to be protected under § 411(d)(6) with respect to the plan of any adopting employer, unless permitted to do so under §§ 1.401(a)–4 and 1.411(d)–4. In addition, an M&P plan that does not contain vesting for all years that is at least as favorable to participants as that provided in § 416(b), must specifically provide that any vesting that occurs

1987–2 C.B. 647, Rev. Proc. 97–29, 1997–1 C.B. 698, and Rev. Proc. 98–59, 1998–2 C.B. 727). .03 Areas Not Covered by Opinion Letters - Opinion letters will not be issued for:

(1) Multiemployer plans and multiple employer plans;

(2) Union plans (This does not preclude an M&P plan from covering employees of the employer who are included in a unit covered by a collective bargaining agreement or the adoption of an M&P plan pursuant to such agreement as a single employer plan that covers only employees of the employer.);

(3) Stock bonus plans; (4) Employee stock ownership plans; (5) Pooled fund arrangements contemplated by Rev. Rul. 81–100, 1981–1 C.B. 326 (as modified by Rev. Rul. 2004–67, 2004–28 I.R.B. 28); (6) Annuity contracts under § 403(b); (7) All cash balance plans and any other defined benefit plans (regardless of whether they are cash balance plans) under which the test for nondiscrimination under § 401(a)(4) is made by reference to contributions rather than benefits;

(8) Plans described in § 414(k) (relating to a defined benefit plan that provides a benefit derived from employer contributions that is based partly on the balance of the separate account of a participant);

(9) Target benefit plans, other than plans which, by their terms, satisfy each of the safe harbor requirements described in § 1.401(a)(4)–8(b)(3)(i), as well as the additional rules in § 1.401(a)(4)–8(b)(3)(ii) through (vii);

(10) Defined benefit plans that provide for employee contributions;

(11) Plans that would not satisfy the qualification requirements except as governmental plans as described in § 414(d);

(12) Church plans described in § 414(e) that have not made the election provided by § 410(d);

(13) Plans under which the § 415 limitations are incorporated by reference;

(14) Plans that incorporate the ADP test under § 401(k)(3) or the ACP test under § 401(m)(2) by reference;

(15) Section 401(k) plans (standardized and nonstandardized) that provide for hardship distributions under circumstances other than those described in the

cation of the language of the trust or custodial account document and the addition of overriding language.

An employer that adopts a standardized M&P plan may amend the trust or custodial account document provided such amendment merely involves the specification of the names of the plan, employer, trustee or custodian, plan administrator and other fiduciaries, the trust year, or the name of any pooled trust in which the plan’s trust will participate.

.10 Provisions Required in Adoption Agreements Regarding Reliance - The adoption agreement of every nonstandardized M&P plan must include, in close proximity to the signature blank, a statement that describes the limitations on employer reliance on an opinion letter without a determination letter and the circumstances under which an employer will have no reliance without a determination letter. See section 19.02 and section 19.03. Standardized plans must also include a similar statement in the adoption agreement that the adopting employer may not rely on the opinion letter issued by the Service but must apply for a determination letter to have reliance under the circumstances described in section 19.01.

.11 Other Provisions Required in Adoption Agreements — Each M&P plan must contain a dated employer signature line. The employer must sign the adoption agreement when it first adopts the plan and must complete and sign a new adoption agreement if the plan has been restated. In addition, the employer must complete a new signature page if it modifies any prior elections or makes new elections in its adoption agreement. The signature requirement may be satisfied by an electronic signature that reliably authenticates and verifies the adoption of the adoption agreement, or restatement, amendment or modification thereof, by the employer. The adoption agreement must state that it is to be used with one and only one specific basic plan document. In addition, the adoption agreement must contain a cautionary statement to the effect that the failure to properly fill out the adoption agreement may result in failure of the plan to qualify. The adoption agreement must also contain a statement that provides that the sponsor will inform the adopting employer of any amendments made to the

plan or of the discontinuance or abandonment of the plan.

.12 Sponsor Telephone Numbers M&P plan adoption agreements must include the sponsor’s name, address and telephone number (or a space for the address and telephone number of the sponsor’s authorized representative) for inquiries by adopting employers regarding the adoption of the plan, the meaning of plan provisions, or the effect of the opinion letter.

.13 Definition of Employee / § 414(b), (c), (m), (n) and (o) - Each M&P plan must include a definition of employee as any employee of the employer maintaining the plan or any other employer aggregated under § 414(b), (c), (m) or (o) and the regulations thereunder. The definition of employee shall also include any individual deemed under § 414(n) (or under regulations under § 414(o)) to be an employee of any employer described in the previous sentence.

.14 Definition of Service / § 414(b), (c), (m), (n), and (o) — Each M&P plan must specifically credit all service with any employer aggregated under § 414(b), (c), (m) or (o) and the regulations thereunder as service with the employer maintaining the plan. In addition, in the case of an individual deemed under § 414(n) (or under regulations under § 414(o)) to be the employee of any employer described in the previous sentence, service with such employer must be credited to such individual.
