SECTION 4. DEFINITIONS

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

.01 Master Plan - A “master plan” is a plan (including a plan covering self-employed individuals) that is made available by a sponsor for adoption by employers and for which a single funding medium (for example, a trust or custodial account) is established, as part of the plan, for the joint use of all adopting employers. A master plan consists of a basic plan document, an adoption agreement, and, unless included in the basic plan document, a trust or custodial account document.

.02 Prototype Plan - A “prototype plan” is a plan (including a plan covering self-employed individuals) that is made available by a sponsor for adoption by employers and under which a separate funding medium is established for each adopting employer. A prototype plan consists of a basic plan document, an adoption agreement, and, unless the basic plan document incorporates a trust or custodial account agreement the provisions of which are applicable to all adopting employers, a trust or custodial account document.

.03 Basic Plan Document - A “basic plan document” is the portion of a plan containing all the non-elective provisions applicable to all adopting employers. No options (including blanks to be completed) may be provided in the basic plan document, except as provided in section 12.03(1) of this revenue procedure regarding flexible plans.

.04 Adoption Agreement — An “adoption agreement” is the portion of the plan containing the options that may be selected by an adopting employer.

.05 Trust or Custodial Account Document ( Note: This definition does not apply if the basic plan document includes a trust or custodial account agreement the provi- sions of which apply to all adopting em- ployers. ) (1) A “trust or custodial account document” is the portion of an M&P plan that contains the trust agreement or custodial account agreement and includes provisions covering such matters as the powers and duties of trustees, investment authority, and the kinds of investments that may be made.

2005–10 I.R.B. 677 March 7, 2005

§ 410(a)(1) or (b)(3) applies uniformly to all employees. A standardized plan generally may not deny an accrual or allocation to an employee eligible to participate merely because the employee is not an active employee on the last day of the plan year or has failed to complete a specified number of hours of service during the year. However, the plan may deny an allocation or accrual to an employee who is eligible to participate if the employee terminates service during the plan year with not more than 500 hours of service and is not an active employee on the last day of the plan year.

(2) The eligibility requirements under the plan are not more favorable for highly compensated employees (as defined in § 414(q)) than for other employees.

(3) Under the plan, allocations, in the case of a defined contribution plan (other than any cash or deferred arrangement part of the plan), or benefits, in the case of a defined benefit plan, are determined on the basis of total compensation. For this purpose, total compensation means a definition of compensation 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) of the Income Tax Regulations.

(4) Unless the plan is a target benefit plan or a § 401(k) and/or § 401(m) plan, the plan must, by its terms, satisfy one of the design-based safe harbors described in § 1.401(a)(4)–2(b)(2) (taking into account § 1.401(a)(4)–2(b)(4)) or in § 1.401(a)(4)–3(b)(3), (4), or (5) (taking into account § 1.401(a)(4)–3(b)(6)).

(5) All benefits, rights, and features under the plan (other than those, if any, that have been prospectively eliminated) are currently available to all employees benefiting under the plan.

(6) Any past service credit under the plan must meet the safe harbor in § 1.401(a)(4)–5(a)(3).

A plan will not fail to satisfy the coverage requirement for standardized plans merely because the plan provides, either as the result of an elective provision or by default in the absence of an election to the contrary, that individuals who become employees, within the meaning of section 5.13, as the result of a “§ 410(b)(6)(C) transaction” will be excluded from eligi

A sponsor may request opinion letters for any number of basic plan documents and adoption agreements provided the 30-employer requirement is met with respect to at least one basic plan document. The Service reserves the right at any time to request from the sponsor a list of the employers that have adopted or are expected to adopt the sponsor’s M&P plans, including the employers’ business addresses and employer identification numbers.

Notwithstanding the above, any person that has an established place of business in the United States where it is accessible during every business day may sponsor a plan as a word-for-word identical adopter or minor modifier adopter of a plan of an M&P mass submitter, regardless of the number of employers that are expected to adopt the plan.

By submitting an application for an opinion letter for an M&P plan under this revenue procedure (or by having an application filed on its behalf by an M&P mass submitter as required for a minor modifier), a person represents to the Service that it is a sponsor, as defined above, and agrees to comply with any requirements imposed on sponsors by this revenue procedure. Failure to comply with these requirements 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.

.08 M&P Mass Submitter — An “M&P mass submitter” is any person that (1) has an established place of business in the United States where it is accessible during every business day and (2) submits opinion letter applications on behalf of at least 30 unaffiliated sponsors each of which is sponsoring, on a word-for-word identical basis, the same basic plan document. A flexible plan (as defined in section 12.03(1)) that is adopted by a sponsor will be considered a word-for-word identical plan. An M&P mass submitter may submit an opinion letter application on its own behalf as one of the 30 unaffiliated sponsors. For purposes of this definition, affiliation is determined under § 414(b) and (c). Additionally, the following will be considered to be affiliated: any law, accounting, consulting firm, etc., with its partners, members, associates, etc. An M&P mass submitter will be treated as an

M&P mass submitter with respect to all its M&P plans provided the 30 unaffiliated sponsor requirement is met with respect to at least one basic plan document.

Notwithstanding the above, any person that received a favorable TRA ’86 opinion letter for a plan as an M&P mass submitter under Rev. Proc. 89–9, 1989–1 C.B. 780, will continue to be treated as an M&P mass submitter with respect to all its M&P plans if it submits applications on behalf of at least 10 sponsors (regardless of affiliation) each of which is sponsoring, on a word-for-word identical basis, the same basic plan document.

.09 National Sponsor - A “national sponsor” is a sponsor that has either (a) 30 or more adopting employers in each of 30 or more states (treating, for this purpose, the District of Columbia as a state) or (b) 3000 or more adopting employers. The determination as to whether there are 3000 or more adopting employers or 30 or more adopting employers in each of 30 or more states may be made on any one date during the 12 month period ending on the date that is 60 days after the effective date of this revenue procedure. For this purpose, an adopting employer is any employer that has adopted any plan of the sponsor that has a GUST opinion letter. GUST is an acronym for the Uruguay Round Agreements Act (GATT), the Uniformed Services Employment and Reemployment Rights Act of 1994 (USERRA), the Small Business Job Protection Act of 1996 (SBJPA), the Taxpayer Relief Act of 1997 (TRA ’97), the Internal Revenue Service Restructuring and Reform Act of 1998 (RRA ’98), and the Community Renewal Tax Relief Act of 2000 (CRA)

.10 Standardized Plan - A “standardized plan” is an M&P plan that meets the following requirements:

(1) The provisions governing eligibility and participation are such that the plan by its terms must benefit all employees described in section 5.13 (regardless of whether any employer is treated as operating separate lines of business under § 414(r)) except those that may be excluded under § 410(a)(1) or (b)(3). The adoption agreement may provide options as to whether some or all of the employees described in § 410(a)(1) or (b)(3) are to be excluded, provided that the criteria for excluding employees described in

while the plan is top-heavy, will not be cut back if the plan ceases to be top-heavy.

.06 Adopting Employer Modification to Satisfy §§ 415 and 416 - M&P plans must provide that the plan provisions may be amended by overriding plan language completed by the employer in the adoption agreement where such language is necessary to satisfy § 415 or 416 because of the required aggregation of multiple plans under these sections. Generally, a space should be provided in the adoption agreement with instructions for the employer to add such language as necessary to satisfy §§ 415 and 416. In addition, a space must be provided in the adoption agreement for the employer to specify the interest rate and mortality tables used for purposes of establishing the present value of accrued benefits in order to compute the top-heavy ratio under § 416. Such a space must be included in both defined contribution plans and defined benefit plans.

.07 Defined Contribution § 415 Aggregation — Plan language must be incorporated that aggregates all defined contribution M&P plans to satisfy § 415(c) and (f). Sample language provided in the Listing of Required Modifications may be downloaded from the Internet at the following address: http://www.irs.gov .

.08 Top-heavy Requirements - Each plan must either provide that all the additional requirements applicable to top-heavy plans (described in § 416) apply at all times or provide that such requirements apply automatically if the plan is top-heavy regardless of how the adoption agreement is completed. In any case where the latter option is chosen, all the requirements for determining whether the plan is top-heavy must be included in the plan. (See Questions T–35 and T–36 of § 1.416–1.)

.09 Adopting Employer Modification of Trust or Custodial Account Document

  • An employer that adopts a nonstandardized M&P plan will not be considered to have an individually designed plan merely because the employer amends administrative provisions of the trust or custodial account document (such as provisions relating to investments and the duties of trustees), provided the amended provisions are not in conflict with any other provision of the plan and do not cause the plan to fail to qualify under § 401(a). For this purpose, an amendment includes modifi

bility to participate in the plan during the period beginning on the date of the transaction and ending on a date that is not later than the last day of the first plan year beginning after the date of the transaction. A “§ 410(b)(6)(C) transaction” is an asset or stock acquisition, merger, or other similar transaction involving a change in the employer of the employees of a trade or business.

.11 Nonstandardized Plan - A “nonstandardized plan” is an M&P plan that is not a standardized plan.
