IRS Form 941-X (2015): Late & Amended Filing Guide
What IRS Form 941-X (2015) Is For
IRS Form 941-X (2015) helps employers correct errors on a previously filed Form 941. This tax form allows businesses to fix overreported and underreported taxes related to federal income tax withheld, Social Security tax, Medicare taxes, and payroll tax credits. Employers use the completed form to correct errors in taxable wages, employees’ pay, or employment tax liability from a prior period. It applies to qualified, taxable Medicare and Social Security wages from the appropriate calendar year.
When You’d Use IRS Form 941-X (2015)
Employers file Form 941-X when they discover mistakes in a previously filed form that affect federal income tax liabilities reported to the state's internal revenue service. You must file within three years from the original filing date or two years from payment, whichever is later. This applies whether correcting underreported taxes, claiming the refundable portion of a payroll tax credit, or addressing overreported tax on wages. Exempt organizations, local governmental entities, and Indian tribal governmental entities are also required to file corrections when necessary. Filing Form 941-X ensures your employment taxes, federal income tax, and Social Security tax are reported accurately.

Step-by-Step (High Level)
Step 1: Gather Records
Employers should collect all original forms, including the previously filed Form 941, along with payroll documents showing taxable Social Security tips, taxable wages, and family leave wages.
Step 2: Complete Form 941-X
Use a separate form for each tax period that needs correction. Indicate whether you are correcting underreported tax amounts or overreported taxes for the correct tax year and employment tax liability.
Step 3: Choose Adjustment or Claim Process
Select the adjustment process if you want interest-free treatment for underreported amount corrections or to apply credits to future returns. Use the claim process to request refunds for overreported taxes.
Step 4: Attach Additional Information
Attach a detailed explanation describing what caused the error, referencing qualified sick pay, coverage beginning dates, or other factors impacting employee wages and taxable income.
Step 5: File Form 941-X by Mail
File the paper form with the Internal Revenue Service using the correct mailing address for your location department. Private delivery service or postal service methods are both acceptable for timely submission.
Step 6: Retain Documentation
Keep copies of the completed form, proof of employee repayment, and documents supporting the payroll tax credit for four years. These records help ensure compliance with all employment taxes and adjustments.
Common Mistakes and How to Avoid Them
- Filing one form for multiple quarters: Each quarter needs a separate form to ensure the tax reported aligns with the specific tax period and the appropriate calendar year.
- Using vague explanations: Always describe the correction for every underreported or overreported tax issue in the original form.
- Missing employee consent: Employers must secure written permission from employees before claiming refunds for overreported taxes involving federal income tax withheld or Medicare wages.
- Incorrect process selection: Choose the claim process for refunds or the adjustment process to correct underreported taxes while maintaining interest-free treatment.
- Forgetting documentation: Employers should always include schedules and qualified health plan expenses documentation for accuracy when they file Form 941-X.
- Improper filing method: Do not use electronic filing; send your paper form using the correct postal service address listed for your legal residence.
What Happens After You File
The IRS reviews the completed Form 941-X and processes corrections based on the tax year and issue type. You may receive confirmation, a refund, or a request for clarification. If your filing shows an underreported amount, payment can be made electronically through the Electronic Federal Tax Payment System or by check. The IRS may grant payment arrangements for qualifying companies that cannot immediately pay their federal tax liabilities. To verify their tax forms, employers should monitor any notices from the state internal revenue service or local departments, such as West Virginia or South Carolina.
