Common Reasons To File Form 941-X
Overreported Wages
You mistakenly reported more wages or tips than you actually paid, leading to an overpayment of Social Security and Medicare taxes.
Underreported Wages
You discovered you paid wages, tips, or other compensation that you didn't include on your original return, resulting in a tax underpayment.
Claiming a Credit
You realize you were eligible for payroll tax credits (like past COVID-19 relief credits) but didn't claim them on your original Form 941.

What To Do Next
You Have an Overpayment (Credit)
Because your corrected tax is less than your original tax, you've overpaid. You have two options on Form 941-X:
- Adjustment Process: Apply the credit to your next Form 941 return, reducing your future tax deposits. This is often the faster option.
- Claim Process: Request a direct refund check from the IRS for the overpaid amount.
Important: To claim a refund of the employees' share of Social Security and Medicare taxes, you must first repay or reimburse your employees and get their written consent.
You Have an Underpayment (Balance Due)
Because your corrected tax is more than your original tax, you owe additional tax. You must use the **Adjustment Process** on Form 941-X and pay the amount due by the time you file the form. Filing and paying promptly can help you avoid interest and penalties.
Your next steps will appear here after you use the simulator above.
Know Your Filing Deadlines
The IRS has strict time limits, called periods of limitation, for making corrections.
To Claim a Refund (Overpayment)
File within **3 years** from the date your original Form 941 was filed, or **2 years** from the date you paid the tax, whichever is later.
To Correct an Underpayment
File within **3 years** from the date your original Form 941 was filed.
Note: For the period of limitations, Forms 941 for a calendar year are considered filed on April 15 of the succeeding year if filed before that date.
