You can self-correct many retirement plan errors without contacting the IRS or paying a fee. There are no application or reporting requirements. Self-correction, also known as the Self-Correction Program or SCP, is authorized under Revenue Procedure 2021-30, the revenue procedure that governs the Employee Plans Compliance Resolution Program (EPCRS). You can self-correct an insignificant operational error at any time to preserve the tax-favored status of your plan. An operational error occurs when you don’t follow the written terms of the plan. Even where the operational error is significant, you may still be able to self-correct if action is taken in a timely manner.
