December 18, 2023 1496 Bulletin No. 2023–51

(4) Discretionary Amendment . The term “Discretionary Amendment” means an amendment that is not an Interim Amendment.

(5) Employer . The term “Employer” means an employer that sponsors a Qualified Pre-approved Plan for its employees or an eligible employer, as described in § 403(b)(1)(A), that sponsors a Section 403(b) Pre-approved Plan for its employees.

(6) Employer Adoption Window. The term “Employer Adoption Window” means the period during which an Adopting Employer must adopt a newly approved Pre-approved Plan for a Cycle, and is also generally the period during which an Adopting Employer of a newly approved Pre-approved Plan may submit an application for a determination letter (if otherwise permitted). See section 5.02 regarding the Employer Adoption Window and section 25 regarding determination letters.

(7) Flexible Plan. The term “Flexible Plan” means a plan submitted by a Mass Submitter that includes optional provisions (as described in section 15.03(1)(b)).

(8) Governmental Plan. The term “Governmental Plan” means a governmental plan within the meaning of § 414(d).

(9) Interim Amendment . The term “Interim Amendment” means an amendment to correct a Disqualifying Provision or a Form Defect that results in the failure of a Pre-approved Plan to satisfy a Qualification Requirement or Section 403(b) Requirement, as applicable, by reason of a change in that requirement, or an amendment that is integral to that Disqualifying Provision or Form Defect. See section 6.04.

(10) Mass Submitter . The term “Mass Submitter” means any person that (a) has an established place of business in the United States where it is accessible during every business day, and (b) submits Opinion Letter applications on behalf of 15 unaffiliated Providers, each of which is offering, on a word-for-word identical basis, the same plan. A Flexible Plan that is offered by a Provider is considered a plan that is word-for-word identical. For purposes of determining whether 15 unaffiliated Providers offer, on a word-for-word identical basis, the same Pre-approved Plan, a Mass Submitter that is also a Provider is treated as an unaffiliated Provider. For purposes of this definition, affiliation is determined under § 414(b) and (c). Additionally, any law firm, accounting firm, consulting firm, or similar organization is considered to be affiliated with its partners, members, associates, or similar affiliated persons. A Mass Submitter is treated as a Mass Submitter with respect to all of its plans, provided the 15-unaffiliated-Provider requirement is met with respect to at least one plan. See section 15 for rules relating to a Mass Submitter’s plans.

(11) Minor Modification. The term “Minor Modification” means a minor change to an otherwise word-for-word identical Pre-approved Plan of the Mass Submitter that the IRS determines does not require an in-depth IRS technical review. For example, a change from five-year 100% vesting to three-year 100% vesting is a minor modification for a defined benefit plan. 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.

(12) Nonstandardized Plan . The term “Nonstandardized Plan” means a Pre-approved Plan that is not a Standardized Plan.

(13) Opinion Letter . The term “Opinion Letter” means a written statement issued by the IRS to a Provider or Mass Submitter that the form of a Qualified Pre-approved Plan or a Section 403(b) Pre-approved Plan satisfies the Qualification Requirements or the Section 403(b) Requirements, respectively, that are being reviewed by the IRS for the Cycle for which the Opinion Letter is being issued.

(14) Pre-approved Plan . The term “Pre-approved Plan” means a plan (including a plan that is word-for-word identical to, or a Minor Modification of, a Mass Submitter’s plan) that has received an Opinion Letter under this revenue procedure (or a predecessor of this revenue procedure) and

Bulletin No. 2023–51 1497 December 18, 2023

that is made available by a Provider for adoption by Employers. A Pre-approved Plan includes a plan covering self-employed individuals. A Pre-approved Plan may be either a Qualified Preapproved Plan or a Section 403(b) Pre-approved Plan. A Qualified Pre-approved Plan or a Section 403(b) Pre-approved Plan may be either a Standardized Plan or a Nonstandardized Plan. A Qualified Pre-approved Plan or a Section 403(b) Pre-approved Plan may be structured as either an Adoption Agreement Plan or a Single Document Plan.

(15) Provider .

(a) The term “Provider” means any person (including, if applicable, a Mass Submitter) that:

(i) Has an established place of business in the United States where it is accessible during every business day, and

(ii) Represents to the IRS in its application for an Opinion Letter that it has at least 15 Employerclients (except as set forth in section 4.01(15)(a)(ii)(A) regarding a Retirement Income Account), each of which is reasonably expected to adopt one of the Provider’s Pre-approved Plans.

(A) A person that is otherwise eligible to be a Provider generally may apply for an Opinion Letter for a Section 403(b) Pre-approved Plan that is intended to be a Retirement Income Account without satisfying the 15‑Employer-client requirement with respect to that plan. However, if that person also applies for an Opinion Letter with respect to a Section 403(b) Pre-approved Plan that is not a Retirement Income Account, the person would need to meet the 15-Employer-client requirement for the plan that is not a Retirement Income Account.

(B) The IRS reserves the right to request from the Provider at any time a list of the Employers that have adopted or are expected to adopt the Provider’s plans, including the Employers’ business addresses and employer identification numbers.

(b) Notwithstanding the preceding provisions of this section 4.01(15), any person that has an established place of business in the United States where it is accessible during every business day may offer a plan that is word-for-word identical to a Mass Submitter’s plan as an identical adopter or a plan that includes Minor Modifications to a Mass Submitter’s plan as a minor modifier adopter regardless of the number of Employers that are expected to adopt the plan. See section 15 for rules relating to a Mass Submitter’s plans, including procedures for identical adopters and minor modifier adopters of a Mass Submitter’s plans.

(c) By submitting an application for an Opinion Letter for a Pre-approved Plan under this revenue procedure (or by having an application filed on its behalf by a Mass Submitter as an identical adopter or a minor modifier adopter), a person represents to the IRS that it is a Provider, and that it agrees to comply with any requirements imposed on Providers by this revenue procedure. Failure to comply with these requirements may result in the loss of eligibility to offer Pre-approved Plans and the revocation of Opinion Letters that have been issued to the Provider.

(16) Related Employers. For a Pre-approved Plan other than a Section 403(b) Pre-approved Plan that is a Governmental Plan, the term “Related Employer” means an employer that is aggregated with the Adopting Employer under § 414(b), (c), (m), and (o) and the regulations thereunder. For a Section 403(b) Pre-approved Plan that is a Governmental Plan, the term “Related Employer” means an employer that is aggregated with the Adopting Employer in a manner consistent with Notice 89-23, 1989‑1 CB 654.

(17) Remedial Amendment Cycle. The term “Remedial Amendment Cycle” means the time period designated by the IRS during which (1) a Provider submits a proposed Pre-approved Plan for review and approval by the IRS, (2) the plan, once approved, is adopted by Employers, and (3) an Adopting Employer of a newly approved Pre-approved Plan generally may submit an application for a determination letter (if otherwise permitted). See section 5.

(18) Remedial Amendment Period. The term “Remedial Amendment Period” means the period during which an employer maintaining a plan may correct Disqualifying Provisions or Form Defects, as applicable, in its plan retroactive to the beginning of that period. As part of the correction of a Disqualifying Provision or a Form Defect within the applicable Remedial Amendment Period, an Adopting Employer is considered to have satisfied the Qualification Requirements or Section 403(b) Requirements, as applicable, if all provisions of the plan that are necessary to satisfy those requirements have been adopted and made effective in form and operation from the beginning of the Remedial Amendment Period. See section 6.

(19) Single Document Plan. The term “Single Document Plan” means a plan offered by a Provider that consists of a single plan document without an adoption agreement. A Single Document Plan may include alternate paragraphs and options that may be selected by an Adopting Employer (including blanks to be completed by the Adopting Employer in accordance with specified parameters).

(20) Standardized Plan . The term “Standardized Plan” means a Pre-approved Plan that satisfies the requirements set forth in section 9.03 or 9.07, as applicable. A Qualified Pre-approved Plan that includes an ESOP or that is a Statutory Hybrid Plan may not be a Standardized Plan.

(21) Submission Period. The term “Submission Period” means the period during which a Provider (including a Mass Submitter) may apply for an Opinion Letter for a particular Cycle. See section 5.02; also see section 16 regarding filings made after the Submission Period.
