Before You Close Out Tax Season: Check Your Rejected Returns

A transmitted return still needs an IRS acceptance acknowledgment. For 2025 Form 1040 returns with a timely Form 4868 extension, the filing deadline was October 15, 2026. The IRS lists October 20, 2026, as the retransmission deadline for rejected extension returns. Have your ERO review rejection codes, assign corrections, retransmit promptly, and save the final acceptance acknowledgment in each client’s file. This correction window does not give every client five extra days to file; disaster relief and other special circumstances may affect individual deadlines
