IRS Issues Cumulative List for Cycle 4 Defined Benefit Plan Updates

WASHINGTON — The Internal Revenue Service has published its cumulative list of changes in plan qualification requirements for the fourth remedial amendment cycle of pre-approved defined benefit pension plans. The notice provides the official guidance that plan providers will use to update their plan documents and apply for new IRS opinion letters. This regularly scheduled update kicks off a multi-year process for providers of these pre-approved retirement plans, which are widely used by small and mid-sized businesses to offer pension benefits without the cost and complexity of a custom-designed plan. The cumulative list details the legislative and regulatory changes that must be incorporated into plan language to ensure they remain in compliance with the Internal Revenue Code. While these cyclical updates are a routine part of benefits administration from the IRS's perspective, they represent a recurring and high-stakes compliance deadline for business owners. The process can be complex, and a failure to properly adopt the updated plan documents within the prescribed window can lead to severe consequences, including the potential disqualification of the plan and the loss of significant tax advantages. The IRS operates a staggered system of remedial amendment cycles for different types of pre-approved retirement plans. Defined contribution plans, such as 401(k)s, and defined benefit plans, which promise a specific monthly benefit at retirement, follow separate timelines. This new notice pertains specifically to defined benefit plans entering their fourth cycle. Earlier this year, the IRS issued Notice 2024-3, a similar cumulative list for defined contribution plans, whose fourth cycle submission period for providers began on February 1, 2024, and runs through January 31, 2025. For defined benefit plans, this new list marks the first major step in their own fourth cycle. The process follows a predictable pattern established in previous cycles. First, the IRS publishes the cumulative list of required changes. Next, pre-approved plan providers—the financial institutions and benefits companies that create and maintain the plan templates—will have a designated submission period to send their updated documents to the IRS for review. After a thorough review process, the IRS will issue new opinion letters, which serve as an official endorsement that the plan's language complies with current law. Once the opinion letters are issued, the IRS will announce a final deadline by which all employers using these pre-approved plans must formally adopt the newly restated documents. This adoption window typically lasts about two years. For context, the third cycle for defined benefit plans, which was based on the 2020 Cumulative List, is currently in its final phase. According to IRS Announcement 2023-6, employers sponsoring those plans have until March 31, 2025, to adopt the updated plan documents from their providers. The release of this new cumulative list is the starting gun for the next multi-year compliance marathon. In our experience, businesses that wait until the final adoption deadline is announced often struggle to review and implement the changes correctly amidst their other operational demands. Proactive planning is essential. We guide our clients through these long-term compliance calendars as part of our tax preparation and compliance services, ensuring no deadline is missed and that plan sponsorship remains a benefit, not a liability. For businesses managing defined benefit plans, understanding these timelines is critical, and the team at C&S Finance Group LLC at csfinancegroup.com can provide that necessary clarity and oversight. The changes included in a cumulative list can range from minor technical corrections to significant shifts resulting from major legislation. Each change must be accurately reflected in the plan document. For the providers, this is a meticulous drafting and review process. For the adopting employers, it requires careful coordination with their plan provider and any third-party administrators to ensure the restated plan is signed and put into effect by the deadline. Adopting a pre-approved plan with a favorable opinion letter provides a business with a high degree of certainty that its retirement plan is qualified in form. This reliance means the employer can be confident that contributions are tax-deductible and that the plan's investment earnings can grow tax-deferred. Maintaining this qualified status is paramount. The remedial amendment cycle is the mechanism the IRS uses to ensure these template plans do not become outdated as laws change, thereby protecting both the employer and its employees. Looking ahead, plan providers will now be analyzing the new cumulative list and preparing their plan documents for submission to the IRS. The agency will subsequently announce the official on-cycle submission window for these Cycle 4 defined benefit plans. Employers currently using a pre-approved defined benefit plan should anticipate hearing from their providers in the coming months about the timeline for the eventual plan restatement.
