PART II. REMEDIAL AMENDMENT CYCLES AND REMEDIAL AMENDMENT PERIODS

SECTION 5. REMEDIAL AMENDMENT CYCLE SYSTEM

Internal Revenue Bulletin 2023-51 · 2026-10-03 edition · updated 2026-10-04 · United States

.01 Remedial Amendment Cycles . Under this revenue procedure, every Pre-approved Plan has a recurring Remedial Amendment Cycle. Providers may apply for new Opinion Letters for each Cycle. Adopting Employers of Pre-approved Plans, if otherwise eligible under section 25, may apply for determination letters once each Cycle. Defined contribution Qualified Pre-approved Plans, defined benefit Qualified Pre-approved Plans, and Section 403(b) Pre-approved Plans each have different Cycles. While the same Cycle applies with respect to all defined contribution Qualified Pre-approved Plans, separate Cycles apply with respect to all defined benefit Qualified Pre-approved Plans and with respect to all Section 403(b) Pre-approved Plans.

.02 Stages of Remedial Amendment Cycle . For each Cycle, a Provider may apply for an Opinion Letter during the Submission Period, which generally begins at or shortly after the beginning of each Cycle. When the IRS’s review of the Pre-approved Plans that are submitted during a Cycle is near completion, the IRS will announce the Employer Adoption Window for that Cycle, during which an Adopting Employer must adopt a newly approved Pre-approved Plan for that Cycle in order to continue to have a Pre-approved Plan. The Employer Adoption Window is also generally the period during which an Adopting Employer of a newly approved Pre-approved Plan may submit for a determination letter, if applicable, pursuant to section 25. 8 The deadline to adopt a newly approved Pre-approved Plan is expected to be a uniform date that will apply to all Adopting Employers. It is expected that the Employer Adoption Window will provide virtually all Employers approximately two years to adopt a newly approved Pre-approved Plan and file for a determination letter, if applicable. A Cycle ends at the end of the last day of the Employer Adoption Window for that Cycle. The next Cycle begins on the following day.

.03 Cycle 4 Submission Period for defined contribution Qualified Pre-approved Plans . Pursuant to this revenue procedure, the Submission Period for a Provider of a defined contribution Qualified Pre-approved Plan to apply for a Cycle 4 Opinion Letter begins on February 1, 2024, and ends on January 31, 2025. A Provider of a defined contribution Qualified Pre-approved Plan may still apply for a Cycle 4 Opinion Letter after the Submission Period. See section 16 regarding filings made after the Submission Period.
