SECTION 11. RECORDKEEPING
Internal Revenue Bulletin 2004-18 · 2026-10-03 edition · updated 2026-10-04 · United States
REQUIREMENTS
.01 Filing of Opinion Letter Application Constitutes Agreement to Comply with Recordkeeping Requirements - By submitting an application for an opinion letter under this revenue procedure (or by having an application filed on its behalf by an M&P mass submitter), an M&P plan sponsor agrees, as provided in section 4.07, to comply with the requirements imposed on the sponsor by this revenue procedure, including the recordkeeping requirements of this section. Failure to comply with the requirements imposed on the sponsor by this revenue procedure 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 Maintenance and Availability of Records of Adopting Employers - An M&P plan sponsor must maintain, or have maintained on its behalf, for each of its plans, a record of the names, business addresses, and taxpayer identification numbers of all employers that have adopted the plan. However, a sponsor need not maintain records with respect to employers that, to the best of the sponsor’s knowledge, ceased to maintain the plan as an M&P plan more than three years earlier. Upon written request, a sponsor must provide to the Service a list of such adopting employers that indicates, to the best of the sponsor’s knowledge, which of such employers continue to maintain the plan as an M&P plan and which of such employers have ceased to maintain the plan as an M&P plan within the preceding three years.

provision, it must offer that provision to all adopting employers. Any optional provision that the Service determines does not meet the requirements of this section will have to be changed to a non-optional provision or deleted from the M&P mass submitter’s plan. The following is an exclusive list of the allowable optional provisions that a flexible plan may contain:
(i) Investment Provisions - An M&P mass submitter may offer a variety of investment provisions in its plan for sponsors to include or delete from their version of the plan. However, the plan as adopted by the sponsor must provide some method for investing trust assets. Investment provisions are those provisions that describe the plan’s methods of investing the trust or custodial funds, including provisions such as the availability of loans and investments in insurance contracts or other funding media, and self-directed investments. (Also see (4) and (5) regarding flexibility permitted in trust or custodial account documents.)
(ii) Administrative Provisions - An M&P mass submitter may offer a variety of administrative provisions in its plan for sponsors to include or delete from their version of the plan. However, the plan as adopted by the sponsor must describe how the plan will be administered. Administrative provisions are those provisions that describe the administration of the plan, including the powers, duties, and responsibilities of a plan’s custodian, trustee, administrator, employer, and other fiduciaries. Administrative provisions include the allocation of responsibilities among fiduciaries, the resignation or replacement of fiduciaries, claims procedures under the plan, and recordkeeping requirements. However, procedural provisions that are required for plan qualification are not administrative provisions under this section. For example, provisions that provide for the notice to participants required by § 417 and recordkeeping required by regulations under §§ 401(k) and (m) are not administrative provisions for purposes of this revenue procedure, and may not be optional provisions.
(iii) Cash or Deferred Arrangement An M&P mass submitter may include a self-contained cash or deferred arrangement (as defined in § 401(k)) for sponsors to include or delete.
the M&P mass submitter under penalty of perjury that the sponsor has adopted an M&P plan that is word-for-word identical, within the meaning of this section, to a plan of the M&P mass submitter, or an M&P plan that is a minor modification of the mass submitter’s plan. Form 4461-B must be typed. If the M&P mass submitter’s plan has been approved by the Service, the sponsor’s request for an opinion letter must identify the letter serial number and date of the opinion letter issued to the M&P mass submitter with respect to that plan. If the sponsor has previously received a letter with respect to a plan that is identical to the M&P mass submitter’s plan, the procedures described in sections 12.04 should be followed. If the sponsor is sponsoring a word-for-word identical plan (including a flexible plan), a copy of the plan need not be submitted. If the M&P mass submitter submits a plan with minor modifications, it must comply with the requirements of section 12.03(2). The application submitted on behalf of the sponsor must include the required user fee. Upon receipt of the request for an opinion letter, described above, the Service will, as soon as clerically feasible, issue an opinion letter to the sponsor.
.03 Definitions — (1) Flexible Plan — (a) In general — A “flexible plan” is a plan submitted by an M&P mass submitter that contains optional provisions (as defined in (b), below). Sponsors that adopt the flexible plan may include or delete any optional provision that is designated as such in the M&P mass submitter’s plan, provided the inclusion or deletion of specific optional provisions conforms to the M&P mass submitter’s written representation to the Service concerning the choices available to sponsors and the coordination of optional provisions. An M&P mass submitter must bracket and identify the optional provisions when submitting such plan to EP Rulings and Agreements and must also provide the Service a written representation describing the choices available to sponsors and the coordination of optional provisions. Thus, such a representation must indicate whether a sponsor’s plan may contain only one of a certain group of optional provisions, may contain only a specific combination of provisions, or may exclude the provisions entirely. Similarly, if the inclusion (or
deletion) of a specific optional provision in a sponsor’s plan will automatically result in the inclusion (or deletion) of any other optional provision, this must be set forth in the M&P mass submitter’s representation. A flexible plan may contain only optional provisions which meet the requirements of (b), below, and must be drafted so that the qualification of any sponsor’s plan will not be affected by the inclusion or deletion of optional provisions. For example, if a sponsor’s defined contribution plan contains an optional provision which allows a portion of a participant’s account to be invested in life insurance, then under the terms of the sponsor’s plan, the application of the proceeds must meet the requirements of §§ 401(a)(11) and 417. A flexible plan adopted by a sponsor which differs from the M&P mass submitter plan only because the sponsor has deleted certain optional provisions from its plan in conformance with the M&P mass submitter’s representation described above will be treated as a word-for-word identical plan to the M&P mass submitter plan. The Service encourages M&P mass submitters to limit the number of optional provisions described in (b)(i) and (ii), below, which they provide under a flexible plan to six investment provisions and six administrative provisions.
(b) Optional Provisions - A flexible plan may contain only optional provisions that comply with the requirements set forth below. The optional provisions may be arranged as separate optional articles or as separate optional provisions within a single article. A flexible plan may also contain optional provisions in the adoption agreement. For example, if an M&P mass submitter flexible plan basic plan document contains an optional provision that would allow for loans under a sponsor’s M&P plan, the adoption agreement could also include an optional provision that would enable an adopting employer to elect whether loans will be available under the plan it adopts. If the sponsor does not wish to enable adopting employers to make loans available under their plans, both the basic plan document optional provision and the adoption agreement optional provision would be deleted from the sponsor’s M&P plan. Sponsors may include or delete optional provisions of M&P mass submitter plans, but once the sponsor has decided to include an optional

permission to that M&P mass submitter to submit additional minor modifications.
.04 Amendments of M&P Mass Submitter Plans - Any plan submitted by an M&P mass submitter must include language designating the M&P mass submitter as agent for the sponsor for purposes of making plan amendments (see section 12.02). Any sponsor that does not wish to make the amendments made by an M&P mass submitter may switch to another M&P mass submitter or may submit an application for an opinion letter on its own behalf. If the M&P mass submitter makes any change to the plan, other than the addition of optional provisions pursuant to section 12.03(1)(c), an amendment described in section 21.02, or a model amendment published by the Service, it must comply with the requirements of section 21.01 of this revenue procedure. In addition, prior to submitting an amendment to EP Rulings and Agreements, the M&P mass submitter must notify the Service of its intention to amend the plan. Such notification should be submitted, in writing, to the address in section 20. The Service will then mail a list to the M&P mass submitter showing all sponsors that have adopted plans that are identical to the M&P mass submitter’s plans, as well as the specific plans adopted by each sponsor. The M&P mass submitter must then submit the amended plan to EP Rulings and Agreements for approval, along with a list identifying all adopting sponsors’ plans that will be amended, a user fee form for each such sponsor, and the appropriate user fee required under section 6.04 of Rev. Proc. 2004–8. All sponsors that have adopted the M&P mass submitter’s plan, are identified on the list submitted to the Service, and for which a user fee has been submitted, will be considered to have made such amendments and will be issued opinion letters. In the case of minor modifier plans, separate Form 4461–B applications must be filed along with copies of the plans as amended, user fee forms, and the user fee required by section 6.04 of Rev. Proc. 2000–8 for minor modifier applications. Copies of the amended plan must be sent to adopting employers and EP Determinations in accordance with section 7.11. Any adopting sponsor that is not included on the list submitted to the Service (or in the case of a minor modifier, for which a Form 4461–B application has not been filed) or
(c) Addition of Optional Provisions by the M&P Mass Submitter - An M&P mass submitter may add additional optional provisions to its plan after a favorable opinion letter is issued. Generally, the addition of such optional provisions will not be treated as a plan amendment for purposes of this revenue procedure, Rev. Proc. 2004–6, and Rev. Proc. 2004–8, 2004–1 I.R.B. 240, and sponsors and adopting employers will not be required to obtain new opinion and determination letters in order to preserve reliance. (However, the addition of a cash or deferred arrangement or any change to the language of the adoption agreement subsequent to the issuance of an opinion letter will be treated as a plan amendment to the M&P mass submitter’s plan and the requirements of subsection .04 will then apply.) The M&P mass submitter must submit such additional optional provisions to the Service, along with a completed Form 4461 or 4461–A, as applicable, and a check or money order in the amount specified in section 6.04(6) of Rev. Proc. 2004–8. No opinion letter will be issued to the M&P mass submitter or any adopting sponsor with respect to the addition of these optional provisions. Instead, a letter will be issued to the M&P mass submitter notifying it that the addition of such optional provisions will not affect the status of favorable opinion and determination letters issued to sponsors and adopting employers.
(d) Notification to Employer - If an M&P mass submitter adds optional provisions, as described in (c), above, all adopting sponsors who wish to include the additional optional provisions must furnish each adopting employer with a copy of the plan that includes such additional provisions. If a sponsor decides to include or delete an optional provision after it initially adopted the plan, it must also furnish each adopting employer with a copy of the new plan. However, if such inclusion or deletion results in a change to the language of the adoption agreement, such change will be treated as a plan amendment and the sponsor and its adopting employers may not continue to rely on previously issued opinion or determination letters.
(2) Minor Modification - A “minor modification” is a minor change to an otherwise word-for-word identical plan of the
M&P mass submitter that does not require an in-depth technical review. For example, a change from 5 year 100% vesting to 3 year 100% vesting is a minor modification. On the other hand, a change in the method of accrual of benefits in a defined benefit plan would not be considered a minor modification. A minor modification must be submitted by the M&P mass submitter on behalf of the sponsor that will adopt the modified plan. Such submissions will be reviewed on an expedited basis and opinion letters will be issued to the sponsor as soon as possible. However, the Service reserves the right to determine if such changes are actually minor. If it is determined that the changes are extensive or require an in-depth technical review, the plan will not be entitled to expedited review but will be treated as a non-mass submitter plan. (In such event, the Service will notify the M&P mass submitter in writing of its determination. Within 30 days following the date of such communication, either the M&P mass submitter may revise the plan so that the modifications are minor and resubmit the revised plan, or the sponsor may submit an additional user fee in an amount equal to the difference between a non-mass submitter plan application user fee and a minor modifier application user fee. If, after such 30 day period neither action has been taken, the application may be considered withdrawn.) To qualify for the expeditious review, the M&P mass submitter must submit a completed Form 4461-B. Such form must be typed. In addition, the M&P mass submitter must submit a copy of the M&P mass submitter’s plan with the minor modifications highlighted, as well as a statement indicating the location and effect of each change. The M&P mass submitter must certify under penalty of perjury that the plan of the sponsor, except for the delineated changes, is word-for-word identical, within the meaning of this section, to the plan for which the M&P mass submitter received a favorable opinion letter. If an M&P mass submitter fails to identify each modification, such failure will be considered a material misrepresentation and an employer may not rely on any opinion or determination letter that may be issued with respect to the plan. If an M&P mass submitter repeatedly fails to identify such modifications, the Service may deny

and (d)(6), to the extent required, in the event that the employer amends the plan in any manner. If a VS plan authorizes the VS practitioner to amend the plan on behalf of employers, the VS practitioner may not amend the 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, a VS plan that is not exempt from the top-heavy requirements and that does not contain vesting for all years which is at least as favorable to participants as that provided in § 416(b), must specifically provide that any vesting that occurs while the plan is top-heavy will not be cut back if the plan ceases to be top-heavy.
.02 Definition of Employee / § 414(b), (c), (m), (n), and (o) - Each VS 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.
.03 Definition of Service / § 414(b), (c), (m), (n), and (o) - Each VS 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.
