SIMPLE-to-401(k) Transition Is Finally… Simple [ DWC ](https://www.dwc401k.com/blog/author/dwc) | Published: 04/7/2026 | [401(k) Plan](https://www.dwc401k.com/blog/topic/401k-plan), [SIMPLE](https://www.dwc401k.com/blog/topic/simple), [SECURE 2.0](https://www.dwc401k.com/blog/topic/secure-2-0) SIMPLE IRA plans have long been the go-to retirement option for small employers — no annual testing, no Form 5500, minimal administration. Employees defer, the employer contributes (3% match or 2% nonelective), done. The problem was never the plan itself. It was the exit. Transitioning to a 401(k) historically required navigating the Exclusive Plan rule and a November 2nd termination notice deadline — a sequence most small businesses missed without a dedicated benefits team watching the calendar. **Why Employers Eventually Outgrow It** A 401(k) opens the door to what a SIMPLE IRA can't offer: **The SECURE 2.0 Fix** Starting in 2024, employers can terminate a SIMPLE IRA mid-year and immediately adopt an eligible replacement plan. That includes: **One Thing to Watch** Because employees may participate in two plans during the transition year, deferral limits must be coordinated across both. The annual limit is prorated based on the portion of the year under each plan — including catch-up contributions. Monitoring this during the transition year is essential. Participants can roll SIMPLE IRA balances into the new 401(k), but the two-year rule still applies: accounts open less than two years from the first deposit carry a 25% early withdrawal penalty on any distribution. **The Bottom Line** A SIMPLE-to-401(k) transition is a growth milestone, and SECURE 2.0 has finally made the mechanics match that moment. If you or your clients are evaluating the move, the [**DWC Team**](https://www.dwc401k.com/contact) can help map out timing, testing implications, and plan design options.   - Share - [**](https://www.facebook.com/sharer/sharer.php?u=https://www.dwc401k.com/blog/why-the-simple-to-401k-transition-is-finally-simple&title=Why%20the%20SIMPLE-to-401(k)%20Transition%20Is%20Finally…%20Simple&picture=https://3113501.fs1.hubspotusercontent-na1.net/hubfs/3113501/Knowledge%20Center/Pillar%20Categories%202024/PNG%20-%20without%20category%20name/hero_pp_png.png&description=Why%20the%20SIMPLE-to-401(k)%20Transition%20Is%20Finally…%20Simple) - [**](https://twitter.com/share?url=https://www.dwc401k.com/blog/why-the-simple-to-401k-transition-is-finally-simple&hashtags=) ## Browse categories [ DWC Developments ](https://www.dwc401k.com/blog/topic/dwc-developments) [ Industry Insights ](https://www.dwc401k.com/blog/topic/industry-insights) [ Regulatory Round-Up ](https://www.dwc401k.com/blog/topic/regulatory-round-up) [ Cash Balance Corner ](https://www.dwc401k.com/blog/topic/cash-balance-corner) [ 401(k) Q&A ](https://www.dwc401k.com/blog/topic/401k-qa) [ Operational Overview ](https://www.dwc401k.com/blog/topic/operational-overview) [ Lessons from Litigation ](https://www.dwc401k.com/blog/topic/lessons-from-litigation) [ Pension Primer ](https://www.dwc401k.com/blog/topic/pension-primer) [ Browse by Topic ](https://www.dwc401k.com/knowledge-center-topics) ## Subscribe to our newsletter ### Only the Best Retirement Industry Content Get our 401(k) and defined benefits content delivered directly to your inbox.
