There are separate Guides for each of the following types of retirement plans: 401(k), 403(b), SEPs, SIMPLEs, and SARSEPs. E ach guide provides (i) an overview of the rules for each type of plan and the Employee Plans Compliance Resolution System, (ii) a description of the most frequent errors found by the IRS for each type of plan, and (iii) guidance on how to find, fix, and avoid the most common errors. Copies of the Guides are available here.
