Form 944-X is the IRS correction form for employers who previously filed Form 944, the annual federal payroll tax return for small businesses. If you discover an error in wages, withholding, or taxes after filing,
Form 944-X lets you correct underreported tax, apply an overreported tax credit to a future return, or claim a refund or abatement. File a separate Form 944-X for each calendar year being corrected.
Only employers who previously filed Form 944 use Form 944-X to correct errors in wages, withheld taxes, or credits. Form 944 is an annual payroll tax return for employers. The IRS has notified them to file it instead of the quarterly Form 941. If you never filed Form 944 for a past year, file the original Form 944 for that year. For errors on any other employment tax return, use the correction form for that specific return.
Form 944-X corrects amounts previously reported on Form 944. Use it to adjust:
Credits for qualified sick and family leave wages, and the COBRA (Consolidated Omnibus Budget Reconciliation Act) premium assistance credit may also be corrected where the period of limitations is still open.
The February 2026 instructions carry 2 OBBBA updates (P.L. 119-21):
Qualified tips and overtime: For 2025 through 2028, employees may deduct up to $25,000 in qualified tips and up to $12,500 ($25,000 if married filing jointly) in qualified overtime on individual returns. Tips and overtime remain subject to Social Security and Medicare tax. Prior-year federal income tax withholding nonadministrative errors linked to these deductions cannot be corrected on Form 944-X.
ERC limitation: OBBBA bars Q3/Q4 2021 ERC claims filed after January 31, 2024, and extends the IRS assessment period to 6 years for those quarters. Keep related records for at least 7 years.
Filing Form 944-X correctly means selecting the right correction process, completing all required sections, and explaining each change in detail.
Form 944-X has no single due date, but timing matters:
Underreported tax: File Form 944-X by the next Form 944 deadline after you find the error (usually January 31) to avoid interest.
Overreported tax: Generally, 3 years from the Form 944 filing date or 2 years from tax payment, whichever is later.
1099Online simplifies Form 944-X preparation with a guided workflow. Here is how it works.
Step 1: Enter Correction and Wage Tax Details.
Log in to your 1099Online account and enter Form 944-X information manually, or import
your payroll data directly. For each line being corrected, enter the corrected amount, the
previously reported amount, and the difference, as required in Part 3 of Form 944-X.
Step 2: Provide your correction explanation.
Explain why you are correcting the original Form 944. The IRS requires this information
on line 43 to process Form 944-X.
Step 3: Review and file.
Confirm your correction summary is complete and accurate, then submit Form 944-X through
1099Online.
There is no threshold for filing Form 944-X. The IRS does not set a minimum correctable amount. Any error in wages, withheld taxes, or credits on a previously filed Form 944 is enough to require a correction.
You do not file Form 944-X with your current Form 944. The IRS requires you to submit it as a separate correction return. There is one exception to the rule, if you are reclassifying workers who were previously treated as nonemployees, the IRS may require you to file Form 944-X alongside the original Form 944 for that year.
You should file Form 944-X as soon as you discover an error. For underreported tax, filing by January 31 of the following year may qualify the correction for interest-free treatment. For overreported tax, the correction window is generally 3 years from the Form 944 filing date or 2 years from when you paid the tax, whichever is later.
If you file Form 944-X late for underreported tax, the correction may lose interest-free treatment. You may need to file Form 945-A if you are a semiweekly depositor correcting deposit liabilities. Without it, the IRS may assess an average failure-to-deposit penalty based on your corrected tax liability.
