Adjusted Employer's Annual Federal Tax Return for Agricultural Employees or Claim for Refund
Read the separate instructions before completing this form. Use this form to correct errors you made on Form 943. Use a separate Form 943-X for each year that needs correction. Type or print within the boxes. You MUST complete all five pages. Don’t attach this form to Form 943 unless you’re reclassifying workers (see line 41).
Part 1: Select ONLY one process. See page 6 for additional guidance, including information on how to treat employment tax credits.
1. Adjusted employment tax return. Check this box if you underreported tax amounts. Also check this box if you overreported tax amounts and you would like to use the adjustment process to correct the errors. You must check this box if you’re correcting both underreported and overreported tax amounts on this form. The amount shown on line 25, if less than zero, may only be applied as a credit to your Form 943 for the tax period in which you’re filing this form. 2. Claim. Check this box if you overreported tax amounts only and you would like to use the claim process to ask for a refund or abatement of the amount shown on line 25. Don’t check this box if you’re correcting ANY underreported tax amounts on this form.
Part 2: Complete the certifications.
3. I certify that I’ve filed or will file Forms W-2 or Forms W-2c, as required. Note: If you’re correcting underreported tax amounts only, go to Part 3 on page 2 and skip lines 4 and 5. If you’re correcting overreported tax amounts, for purposes of the certifications on lines 4 and 5, Medicare tax doesn’t include Additional Medicare Tax. Form 943-X can’t be used to correct overreported amounts of Additional Medicare Tax unless the amounts weren’t withheld from employee wages.
4. If you checked line 1 because you’re adjusting overreported federal income tax, social security tax, Medicare tax, or Additional Medicare Tax, 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 tax and Medicare tax for prior years. I have a written statement from each affected employee stating that they haven’t claimed (or the claim was rejected) and won’t 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 couldn’t find the affected employees; or each affected employee didn’t give me a written statement that they haven’t claimed (or the claim was rejected) and won’t 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 didn’t withhold from employee wages.
5. If you checked line 2 because you’re claiming a refund or abatement of overreported federal income tax, social security tax, Medicare tax, or Additional Medicare Tax, 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 tax and Medicare tax for prior years. I have a written statement from each affected employee stating that they haven’t claimed (or the claim was rejected) and won’t 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 tax and Medicare tax overcollected in prior years. I also have a written statement from each affected employee stating that they haven’t claimed (or the claim was rejected) and won’t claim a refund or credit for the overcollection. c. The claim for social security tax and Medicare tax is for the employer’s share only. I couldn’t find the affected employees; or each affected employee didn’t give me a written consent to file a refund claim for the employee’s share; or didn’t give me the written statement above. d. The claim is for federal income tax, social security tax, Medicare tax, or Additional Medicare Tax that I didn’t withhold from employee wages.
