Whether you’re adjusting underreported taxes or claiming a refund for overreported amounts, understanding Form 944-X is essential for compliance and avoiding penalties. In this comprehensive 2025 guide, we’ll cover everything from eligibility to step-by-step filing instructions, drawing directly from the latest IRS resources. If you’re searching for “how to file IRS Form 944-X” or “Form 944-X deadline,” you’ve come to the right place.

What Is IRS Form 944-X?
IRS Form 944-X, titled Adjusted Employer’s Annual Federal Tax Return or Claim for Refund, is the official tool for correcting errors on your previously filed Form 944 (Employer’s Annual Federal Tax Return). This form allows employers to amend reported amounts for wages, tips, federal income tax withheld, Social Security and Medicare taxes, and specific credits like the qualified small business payroll tax credit.
Key purposes include:
- Adjustments: Correct underreported (pay more) or overreported (credit to future returns) taxes without a refund.
- Claims: Seek refunds or abatements for overreported taxes only.
- Special Corrections: Handle reclassifications of workers or expired COVID-era credits (e.g., qualified sick and family leave wages from 2020-2021).
Use a separate Form 944-X for each tax year corrected—don’t mix years. The April 2025 revision reflects updates like expired limitations periods for many 2020-2021 credits, ensuring you only report eligible items.
Who Needs to File Form 944-X?
Form 944-X is designed for employers who file Form 944 annually (typically small employers with low quarterly tax liability). You must file if:
- You discover errors in wages, tips, withheld taxes, or credits on a prior Form 944.
- You’re reclassifying independent contractors as employees (or vice versa) under Section 3509 rates.
- You’re claiming overlooked credits, such as the qualified small business payroll tax credit (now up to $500,000 for tax years after December 31, 2022).
Who shouldn’t file? Use other forms like 941-X for quarterly filers or 943-X for agricultural employers. If you never filed Form 944 but should have, submit the original Form 944 first.

When Is the Deadline to File IRS Form 944-X?
Timing is critical to avoid interest, penalties, or missed refunds. Deadlines depend on the error type and discovery date:
- Underreported Taxes: File by January 31 of the year following discovery (e.g., for an error found in 2025, file by January 31, 2026). Pay any owed amount by then to stop interest accrual.
- Overreported Taxes (Adjustments): File promptly after discovery, but at least 90 days before the statute of limitations expires—generally 3 years from the original Form 944 filing date (or 2 years from payment, whichever is later). Forms filed before April 15 are treated as filed on April 15.
- Overreported Taxes (Claims for Refund): File anytime within the limitations period.
2025 Note: Many COVID-related credits (e.g., employee retention credit for 2020-2021) have expired limitations as of April 15, 2024-2025. Lines for these (e.g., 17a, 23, 24) are now reserved—leave blank unless your period is still open.
File late? It’s postmarked timely if mailed by the due date or sent via private delivery service (PDS) to the correct address.
