1 Employer & quarter being corrected

One Form 941-X corrects one quarter. Use the current April 2026 IRS revision for corrections to the selected year. Form 941-SS is not used for original 2025 or 2026 returns.

2 Select the lines to correct

Add only the lines that changed. Enter the correct total and the amount originally reported or previously corrected. Differences and standard-rate tax corrections update automatically.

3 Process & certifications

A claim is for overreported tax only. The correct process depends on the individual corrections and deadline rules, not just the final net amount.

Within this period, overreported taxes use the claim process. Mixed corrections require separate adjustment and claim forms. Review the decision guidance on page 6.

Select only statements that are true. Read the complete certifications on the original first page before selecting them.

4 Explain the corrections

For reclassified workers, enter each applicable tax correction from your instruction-supported records. Standard combined-share rates may not apply.

Use at most 2,400 characters in the original field. Prepare any required separate statements or attachments yourself; this tool does not generate them.
