IRS Notice 2026-34: Defined Benefit Pre-approved Plan Cycle 4 Cumulative List
For defined benefit plan providers and the sponsors that adopt pre-approved plan documents, IRS Notice 2026-34 is the operational roadmap for the next opinion letter cycle. The notice publishes the 2026 Cumulative List identifying every qualification change since Cycle 3 that must be reflected in plan documents submitted for defined benefit pre-approved plan Cycle 4 review. With the submission window opening August 1, 2026 and closing July 31, 2027, providers have a defined runway — but the list of incorporated changes is substantial.
At SW Accounting & Consulting Corp, we work with ERISA plan sponsors and providers navigating qualification compliance, plan design, and remedial amendment cycles. This guide breaks down what the notice covers, the Cycle 4 mechanics, the statutory changes incorporated, and what providers and sponsors should do now.
What is the pre-approved plan remedial amendment cycle? 🔄
Under Rev. Proc. 2023-37, every pre-approved retirement plan operates on a recurring remedial amendment cycle. Providers submit plan documents for IRS opinion letters during a defined submission window; adopting employers can then rely on those opinion letters for qualification.
Three separate cycle tracks exist:
- Defined contribution qualified pre-approved plans — 401(k), profit-sharing, money purchase, ESOP plans.
- Defined benefit qualified pre-approved plans — traditional DB, cash balance, hybrid DB plans (the focus of Notice 2026-34).
- Section 403(b) pre-approved plans — for educational, religious, and certain tax-exempt employers.
Each track runs independently. Notice 2026-34 addresses only the DB cycle.
When does the Cycle 4 submission window open and close? 📅
| Milestone | Date |
|---|---|
| Cycle 4 began | April 1, 2025 |
| 2026 Cumulative List published | Notice 2026-34 (May 16, 2026) |
| Cycle 4 submission window opens | August 1, 2026 |
| Cycle 4 submission window closes | July 31, 2027 |
Providers have approximately 12 months to compile plan documents reflecting all Cumulative List items, submit to the IRS for opinion letters, and finalize before the window closes. Adopting employers then rely on those issued opinion letters for their own plan qualification.
Cycle 4 documents must NOT include legislation enacted or guidance issued after Notice 2026-34. Providers who anticipate further SECURE 2.0 implementation guidance or other rulemaking between now and August 2026 should plan two-track drafting: the Cycle 4 submission per the Cumulative List, and a discretionary amendment pathway for post-notice developments.
What statutory changes does the 2026 Cumulative List incorporate? 📋
The 2026 Cumulative List captures qualification changes from SECURE Act (2019), Bipartisan American Miners Act (2019), CARES Act (2020), COVID-related Tax Relief Act of 2020, SECURE 2.0 Act (2022), and related Treasury / IRS regulatory guidance issued through the notice date.
| Statutory Source | Affected Areas |
|---|---|
| SECURE Act (Pub. L. 116-94, Div. O) | Required minimum distributions (RMD age increase), part-time employee eligibility, multiple-employer plan rules, lifetime income disclosures |
| Miners Act (Pub. L. 116-94, Div. M, § 104) | Lower minimum age for in-service distributions (age 59½ → 59½, with some flexibilities) |
| CARES Act §§ 2202, 2203 | COVID-related distributions, loan modifications, RMD waivers |
| COVID-related Tax Relief Act of 2020 § 280 | Disaster-related distribution and loan provisions |
| SECURE 2.0 Act | RMD age phased increase to 75, expanded automatic enrollment, emergency distribution allowances, Roth catch-up requirements, and many other items (subject to the deadlines IRS has identified) |
| Treasury regulations and IRB guidance | Final and proposed regulations implementing the above statutes, plus other published guidance |
The Cumulative List is intentionally LIMITED to qualification-relevant items affecting plan form. It does NOT include routine ministerial guidance (e.g., annual cost-of-living adjustment notices). It also does not extend the deadline by which a plan must be amended to comply with any change — those deadlines come from Rev. Proc. 2023-37 § 7 and Notice 2024-2 Q&A J-1. Providers should track both the Cumulative List AND the underlying amendment deadlines separately.
How is the Cumulative List different from the Operational Compliance List? ⚖
The Cumulative List addresses the form of the plan document submitted for IRS opinion letters. The Operational Compliance List, by contrast, identifies qualification changes that are effective during a given calendar year and must be reflected in plan operations regardless of whether the document has been amended.
Practical distinction:
- Cumulative List — what the plan document must say. Updated for each remedial amendment cycle.
- Operational Compliance List — what the plan must do in practice. Updated periodically as new guidance is published.
- Plan failure risk — even if the plan document is approved under the Cumulative List, operational deviation from current Operational Compliance List items can disqualify the plan.
For the current Operational Compliance List, plan sponsors and providers should reference the IRS Retirement Plans portal directly.
What does Cycle 4 mean for plan sponsors that adopt pre-approved plans? 🏢
Plan sponsors that adopt a pre-approved DB plan document receive reliance on the provider’s IRS opinion letter — provided the sponsor adopts the plan within the applicable timeframe and doesn’t add provisions inconsistent with the pre-approved framework.
Sponsor-level considerations:
- Adoption deadline. Cycle 4 opinion letters, once issued, set the window for sponsor adoption. Typically sponsors must adopt the restated plan within a specified period after the IRS issues the opinion letter.
- Discretionary amendments. Sponsors can adopt discretionary amendments to add or remove optional features, but those amendments must be timely and not conflict with pre-approved language.
- Interim amendments. Required statutory or regulatory amendments between cycles must be adopted under interim amendment rules.
- Operational compliance. Operating per the Cumulative List items even before the plan document is updated — operational defects can disqualify the plan irrespective of document approval status.
What should DB plan providers and sponsors do now? ✅
- Providers: Begin drafting Cycle 4 documents now. 12-month submission window opens August 1, 2026. Build the document framework before the window opens to allow time for internal review, sponsor preview, and IRS revisions.
- Providers: Map every Cumulative List item to plan provisions. Each statutory and regulatory change should have a corresponding plan provision (or documented rationale for no change required).
- Sponsors: Confirm operational compliance. Even before Cycle 4 documents are restated, plans must operate per current qualification requirements. Pull the IRS Operational Compliance List and audit current plan operations.
- Sponsors: Track interim amendment deadlines. Any required amendments between Cycle 3 and Cycle 4 must be adopted timely per Rev. Proc. 2023-37 § 7.
- Coordinate with TPAs and providers. Third-party administrators and document providers should be aligned on the Cycle 4 timeline, sponsor adoption requirements, and any discretionary feature decisions.
- Monitor post-Notice guidance. SECURE 2.0 implementation guidance is still being issued. Items released after May 16, 2026 won’t be in Cycle 4 documents but may require interim amendments after restatement.
