Part 1: Select ONLY one process. See page 4 for additional guidance.

1. Adjusted employment tax return. Check this box if you underreported amounts. Also

check this box if you overreported amounts and you would like to use the adjustment

process to correct the errors. You must check this box if you are correcting both

underreported and overreported amounts on this form. The amount shown on line 20, if

less than zero, may only be applied as a credit to your Form 941, Form 941-SS, or 

Form 944 for the tax period in which you are filing this form.

2. Claim. Check this box if you overreported amounts only and you would like to use the

claim process to ask for a refund or abatement of the amount shown on line 20. Do not

check this box if you are correcting ANY underreported amounts on this form.

Part 2: Complete the certifications.

3. I certify that I have filed or will file Forms W-2, Wage and Tax Statement, or Forms W-2c, Corrected Wage and Tax Statement, 

as required.

Note. If you are correcting underreported amounts only, go to Part 3 on page 2 and skip lines 4 and 5. If you are correcting overreported 

amounts, for purposes of the certifications on lines 4 and 5, Medicare tax does not include Additional Medicare Tax. Form 941-X cannot be 

used to correct overreported amounts of Additional Medicare Tax unless the amounts were not withheld from employee wages or an 

adjustment is being made for the current year.

4. If you checked line 1 because you are adjusting overreported amounts, check all that apply. You must check at least one box.

I certify that:

a. I repaid or reimbursed each affected employee for the overcollected federal income tax or Additional Medicare Tax for the current 

year and the overcollected social security and Medicare taxes for current and prior years. For adjustments of employee social 

security and Medicare taxes overcollected in prior years, I have a written statement from each employee stating that he or she has 

not claimed (or the claim was rejected) and will not claim a refund or credit for the overcollection.

b. The adjustments of social security tax and Medicare tax are for the employer’s share only. I could not find the affected employees 

or each employee did not give me a written statement that he or she has not claimed (or the claim was rejected) and will not claim 

a refund or credit for the overcollection.

c. The adjustment is for federal income tax, social security tax, Medicare tax, or Additional Medicare Tax that I did not withhold from 

employee wages.

5. If you checked line 2 because you are claiming a refund or abatement of overreported employment taxes, check all that apply. 

You must check at least one box. 

I certify that:

a. I repaid or reimbursed each affected employee for the overcollected social security and Medicare tax. For claims of employee 

social security and Medicare tax overcollected in prior years, I have a written statement from each employee stating that he or she 

has not claimed (or the claim was rejected) and will not claim a refund or credit for the overcollection.

b. I have a written consent from each affected employee stating that I may file this claim for the employee’s share of social security 

and Medicare tax. For refunds of employee social security and Medicare tax overcollected in prior years, I also have a written 

statement from each employee stating that he or she has not claimed (or the claim was rejected) and will not claim a refund or 

credit for the overcollection.

c. The claim for social security tax and Medicare taxes is for the employer’s share only. I could not find the affected employees; or 

each employee did not give me a written consent to file a claim for the employee’s share of social security and Medicare taxes; or 

each employee did not give me a written statement that he or she has not claimed (or the claim was rejected) and will not claim a 

refund or credit for the overcollection.

d. The claim is for federal income tax, social security tax, Medicare tax, or Additional Medicare Tax that I did not withhold from 

employee wages.
