A retirement plan needs regular care to keep it operating properly. Your plan’s care should include a regular review of your plan’s basic operations. These one-page checklists are a quick way to start your review. Each checklist links to a Fix-It Guide with tips on how to find, fix and avoid each potential error. SIMPLE IRA Checklist PDF SEP Checklist PDF SARSEP Checklist PDF 401(k) Plan Checklist PDF 403(b) Plan Checklist PDF The checklist is for your use on a voluntary basis. Don’t file it with the IRS. Also, remember that the checklists aren’t meant as a comprehensive review of every aspect of your plan – just an easy way to start. Sample checklist questions: Has your plan document been updated within the past few years to reflect recent law changes? Are the plan’s operations based on the plan document’s terms? Are all eligible employees participating in the plan? What do your checklist answers mean? Answering “no” to any of the checklist questions tells you that you may have a mistake in your plan operation. The expanded explanation for each question – the “Fix-it Guide” - gives you an example of how to correct the mistake. Errors you might find: Your checklist answers might uncover the following common mistakes: not covering the proper employees not giving employees required information not depositing employee deferrals timely not depositing employer contributions timely not following the terms of the plan document not limiting employee deferrals and employer contributions to the proper maximum limits Need to make a correction?
