What IRS Form 941-X (2020) Is For

Form 941-X (2020) is used to correct mistakes on a previously filed Form 941, Employer’s Quarterly Federal Tax Return. Employers use Form 941-X to correct errors in the federal income tax withheld, Social Security tax, Medicare taxes, and other employment taxes reported on Form 941. It also corrects overreported and underreported taxes, including payroll tax credits and employment tax liability errors. Exempt organizations, indian tribal governmental entities, and local governmental entities must file this form when they identify errors in previously filed returns.

Step-by-Step (High Level)

Step 1: Gather Required Records

Collect your original Form 941, wage data, employment taxes, and any supporting details for federal income tax and taxable Social Security wages to ensure accuracy.

Step 2: Complete Form 941-X

Use a separate form for each quarter. Enter corrections for overreported taxes or underreported amounts and include a detailed explanation describing what caused the error.

Step 3: Attach Supporting Schedules

Include amended Schedule B, worksheets, and documentation for qualified wages, previously filed form data, and any payroll tax credit or family leave wage corrections.

Step 4: File Form 941

You can file electronically or by mail using the correct IRS address based on your legal residence. Some state departments, like the Wisconsin or Wyoming departments, may require copies.

Step 5: Maintain Records

Keep your completed form, tax-reported data, and correspondence for at least four years after the tax period. This helps verify any later adjustments or IRS inquiries.

Common Mistakes and How to Avoid Them

• Filing Too Early: File Form 941-X only after the original return has been processed to prevent delays in correcting employment tax liability.
  
  
• Wrong Process Selection: When correcting reported federal tax liabilities, choose either the adjustment or claim processes, but not both.
  
  
• Missing Employee Consent: To comply with refund rules, obtain consent before refunding employee portions of Social Security or Medicare tax.
  
  
• Incomplete Explanations: Provide a clear, detailed explanation of all corrections, especially when adjusting underreported tax or qualified health plan expenses.
  
  
• Missing Attachments: Always attach the amended Schedule B and required documentation for payroll taxes and tax credits to avoid IRS correspondence.
  
  
• Late Corrections: File before the refund expires. The window closes to preserve your right to correct errors or claim overreported tax refunds.
