IRS Form 941-X (2016): Late & Amended Filing Guide
What IRS Form 941-X (2016) Is For
IRS Form 941-X allows employers to correct errors on a previously filed form for the same tax year. It applies when you must adjust reported wages, employment taxes, or federal income tax withheld for a prior period. Employers use this tax form to report corrections for overreported and underreported taxes, including federal income tax, Social Security tax, Medicare taxes, and the additional Medicare tax withholding. The employer and paid preparer must sign the completed form before mailing it to the appropriate IRS address.
When You’d Use Form 941-X for 2016
Employers file Form 941-X when they discover mistakes after filing an original return or receive IRS notices about incorrect amounts. You may file to correct underreported taxes, claim the refundable portion of tax credits, or fix federal tax liabilities reported in prior quarters. Qualifying companies, including exempt organizations, Indian tribal governmental entities, and local governmental entities, use this form to correct overreported tax or claim credits, such as employee retention and COBRA premium assistance credit. The IRS allows late or amended filings within three years of the tax period’s due date.
Key Rules or Details for 2016
- COBRA Premium Assistance Credit: Employers claiming the COBRA premium assistance credit had to file a separate Form 941-X for the same tax period to claim the refundable portion correctly.
- Qualified Sick and Family Leave Wages: Employers who paid qualified sick or family leave wages under specific 2016 provisions had to report those as taxable wages and include related qualified health plan expenses.
- Employment Tax Liability Reporting: Each correction must reflect the proper employment tax liability for the quarter, ensuring the amounts match federal income tax withheld, Medicare wages, and taxable Social Security wages.
- Underreported and Overreported Taxes: When correcting overreported and underreported taxes, explain each underreported amount or overreported tax in the claim process section.
- Legal Residence and Filing Address: Use your current legal residence and the mailing address for your location department or state internal revenue service, including regions such as the Wisconsin or Wyoming Department.
- Private Delivery Service Option: To ensure timely delivery before the due date, taxpayers may use a private delivery service approved by the IRS when mailing the completed form.

Describe why the change occurred and how you will correct underreported taxes or overreported tax amounts. Include detailed references to gross income and the employee’s pay details.
Step 5: Attach Supporting Documentation
Attach schedules showing taxable Social Security wages, Medicare wages, and qualified health plan expenses used to determine the corrections and payroll tax credit claims.
Step 6: Mail or Electronically File the Form

Common Mistakes and How to Avoid Them
- Filing One Form for Multiple Quarters: File Form 941-X separately for each tax period. Combining corrections for multiple tax years delays processing and confuses tax-reported data.
- Omitting Employer Identification Number: Always include your employer identification number and ensure it matches prior filings to avoid having your claim process or refund request rejected.
- Incorrect Reporting of Wages: Verify that taxable, Social Security, and Medicare wages match payroll records to prevent errors in federal income tax withheld.
- Failing to Explain Changes: Each corrected line must include a detailed written explanation. The IRS uses this explanation to confirm the accuracy of overreported and underreported taxes.
- Ignoring Employee Repayments: When correcting overreported taxes, repay affected employees before filing. This ensures both the employer and employee tax accounts remain accurate.
- Late Submission Without Tracking: Always track your filing through the postal service or an approved private delivery service. This protects your claim if the IRS questions submission timing.
What Happens After You File
After submitting Form 941-X, the IRS reviews the information for accuracy and completeness. Most claims or adjustments are processed within twelve weeks. If the IRS finds an underreported amount, you may receive a notice requesting payment. Overreported tax corrections that qualify for a refund are typically issued as checks or credits for future employment taxes. You can contact the IRS or your state's internal revenue service to confirm processing updates for the appropriate calendar year.
