Use a Separate Form 943-X for Each Year You¡¯re Correcting

Use a separate Form 943-X for each Form 943 that you¡¯re correcting. For example, if you found errors on your Forms 943 for 2023 and 2024, file one Form 943-X to correct the 2023 Form 943, and file a second Form 943-X to correct the 2024 Form 943.

Employer Identification Number (EIN), Name, and Address

Enter your EIN, name, and address in the spaces provided. Also enter your name and EIN on the top of pages 2, 3, 4, and 5, and on any attachments. If your address has changed since you filed your Form 943, enter the corrected information and the IRS will update your address of record. Be sure to write your name, EIN, ¡°Form 943-X,¡± and the calendar year you¡¯re correcting on the top of any attachments.

Return You¡¯re Correcting

Enter the calendar year of the Form 943 you¡¯re correcting in the box at the top of page 1. Enter the same calendar year on pages 2, 3, 4, and 5, and on any attachments.

Enter the Date You Discovered Errors

You must enter the date you discovered errors. You discover an error when you have enough information to be able to correct the error. If you¡¯re reporting several errors you discovered at different times, enter the earliest date you discovered an error here. Report any subsequent dates and related errors on line 41.

Must You Make an Entry on Each Line?

You must provide all of the information requested at the top of Form 943-X, page 1. You must check one box (but not both) in Part 1. In Part 2, you must check the box on line 3 and any applicable boxes on lines 4 and 5. In Part 3, if any line doesn't apply, leave it blank. Complete Parts 4 and 5 as instructed.

How Should You Report Negative Amounts?

Form 943-X uses negative numbers to show reductions in tax (credits) and positive numbers to show additional tax (amounts you owe).

When reporting a negative amount in columns 3 and 4, use a minus sign instead of parentheses. For example, enter ¡°-10.59¡± instead of ¡°(10.59).¡± However, if you¡¯re completing the return on your computer and your software only allows you to use parentheses to report negative amounts, you may use them.

How Should You Make Entries on Form 943-X?

You can help the IRS process Form 943-X timely and accurately if you follow these guidelines.

What About Penalties and Interest?

Generally, your correction of an underreported tax amount won¡¯t be subject to an FTP penalty, an FTD penalty, or interest if you:

No correction will be eligible for interest-free treatment if any of the following apply.

If you receive a notice about a penalty after you file this return, reply to the notice with an explanation and we will determine if you meet reasonable-cause criteria. Don¡¯t attach an explanation when you file your return.

If you underreported the tax.

If you underreported the tax on a previously filed Form 943, check the box on line 1 and pay any additional amount you owe by the time you file Form 943-X. For details on how to make a payment, see the instructions for line 25, later.

If you overreported the tax.

If you overreported the tax on a previously filed Form 943, choose one of the following options.

To ensure that the IRS has enough time to process a credit for an overreporting tax adjustment in the year during which you file Form 943-X, you¡¯re encouraged to file Form 943-X correcting the overreported tax amount in the first 11 months of a year. For example, if you discover an overreported tax amount in December, you may want to file Form 943-X during the first 11 months of the next year. However, there must be 90 days remaining on the period of limitations when you file Form 943-X. See the Caution under Is There a Deadline for Filing Form 943-X, earlier. This should ensure that the IRS will have enough time to process Form 943-X so the credit will be posted before you file Form 943, thus avoiding an erroneous balance due notice from the IRS. See the example.

1. Adjusted Employment Tax Return

Check the box on line 1 if you¡¯re correcting underreported tax amounts or overreported tax amounts and you would like to use the adjustment process to correct the errors.

If you¡¯re correcting both underreported tax amounts and overreported tax amounts on this form, you must check this box. If you check this box, any negative amount shown on line 25 will be applied as a credit (tax deposit) to your Form 943 for the year in which you¡¯re filing this form. See Example¡ªYou want your overreported tax applied as a credit to Form 943 , earlier.

Form 943-X can't be used to correct overreported amounts of Additional Medicare Tax unless the amounts weren¡¯t withheld from employee wages.

2. Claim

Check the box on line 2 to use the claim process if you¡¯re correcting overreported tax amounts only and you¡¯re claiming a refund or abatement for the negative amount (credit) shown on line 25. Don¡¯t check this box if you¡¯re correcting any underreported tax amounts on this form.

You must check the box on line 2 if you have a credit (a negative amount on line 25) and the period of limitations on credit or refund for Form 943 will expire within 90 days of the date you file Form 943-X. See Is There a Deadline for Filing Form 943-X , earlier.

The IRS usually processes claims shortly after they are filed. The IRS will notify you if your claim is denied, accepted as filed, or selected to be examined. See Pub. 556, Examination of Returns, Appeal Rights, and Claims for Refund, for more information.

Unless the IRS corrects Form 943-X during processing or you owe other taxes, penalties, or interest, the IRS will refund the amount shown on line 25, plus any interest that applies.

You may not file a refund claim to correct federal income tax or Additional Medicare Tax actually withheld from employees.

3. Filing Forms W-2 or Forms W-2c

Check the box on line 3 to certify that you filed or will file Forms W-2 or Forms W-2c with the Social Security Administration (SSA), as required, showing your employees' correct wage and tax amounts. See the General Instructions for Forms W-2 and W-3 for detailed information about filing requirements.

You must check the box on line 3 to certify that you filed Forms W-2 or Forms W-2c even if your corrections on Form 943-X don¡¯t change amounts shown on those forms. For example, if your only correction to Form 943 involves misstated tax adjustments, which don't impact the amounts reported on your employees¡¯ Forms W-2 (see the instructions for line 12, later), check the box on line 3 to certify that you already filed all required Forms W-2 and W-2c with the SSA. In this situation, you're certifying that you don't need to file Form W-2c because you already filed a correct Form W-2.

4. Certifying Overreporting Adjustments

If you overreported federal income tax, social security tax, Medicare tax, or Additional Medicare Tax and checked the box on line 1, check the appropriate box on line 4. You may need to check more than one box. If you obtained written statements from some employees but you couldn¡¯t locate employees or secure the statements of the remaining employees, check all applicable boxes. Provide a summary on line 41 of the amount of the corrections for the employees who provided written statements and for those who didn¡¯t.

You may not use Form 943-X to correct overreported amounts of Additional Medicare Tax unless the amounts weren¡¯t withheld from employee wages.

5. Certifying Claims

If you¡¯re filing a claim for refund or abatement of overreported federal income tax, social security tax, Medicare tax, or Additional Medicare Tax and checked the box on line 2, check the appropriate box on line 5. You may need to check more than one box. If you obtained written statements or consents from some employees but you couldn¡¯t locate employees or secure the statements of the remaining employees, check all applicable boxes. Provide a summary on line 41 of the amount of the corrections for the employees who provided statements or consents and for those who didn¡¯t.

You may not file a refund claim to correct the incorrect amount of federal income tax or Additional Medicare Tax actually withheld from employees. If you request their consent to file a claim for social security tax or Medicare tax, you must tell your employees that you can't claim a refund of any Additional Medicare Tax on their behalf. See Rev. Proc. 2017-28 for sample language to use in your request.

In certain situations, you may not have repaid or reimbursed your employees or obtained their consents before filing a claim, such as in cases where the period of limitations on credit or refund is about to expire. In those situations, file Form 943-X but don¡¯t check a box on line 5. Tell us on line 41 that you haven¡¯t repaid or reimbursed employees or obtained consents at the time you file the claim. However, you must repay or reimburse your employees and certify that you have done so before the IRS can allow the claim.

What Amounts Should You Report in Part 3?

On lines 6¨C11, columns 1 and 2, for each line you¡¯re correcting, show amounts for all of your employees, not just for those employees whose amounts you¡¯re correcting.

If a correction that you report in column 4 includes both underreported and overreported amounts (see the instructions for line 39, later), give us details for each error on line 41.

Because special circumstances apply for lines 12¨C14, 15b¨C19, 23, 24b, 24c, 26, 27, and 31¨C36, read the instructions for each line carefully before entering amounts in the columns.

If any line doesn't apply to you, leave it blank.

If you previously adjusted or amended Form 943 using Form 943-X or because of an IRS examination change, show amounts in column 2 that include those previously reported corrections.

6. Wages Subject to Social Security Tax

Qualified sick leave wages and qualified family leave wages for leave taken after March 31, 2021, and before October 1, 2021, were included on Form 943, line 2, and can be adjusted only on Form 943-X, line 6.

If you¡¯re correcting the taxable social security wages you reported on Form 943, line 2, enter the total corrected amount for all employees in column 1. In column 2, enter the amount you originally reported or as previously corrected. In column 3, enter the difference between columns 1 and 2.

If you or the IRS previously corrected the amount reported on Form 943, line 2, enter in column 2 the amount after any previous corrections.

Multiply the amount in column 3 by 0.124 (12.4% tax rate) and enter that result in column 4.

7. Qualified Sick Leave Wages (For Leave Taken After March 31, 2020, and Before April 1, 2021)

Generally, the period of limitations for correcting qualified sick leave wages paid in 2020 expired on April 15, 2024, for most employers. Generally, the period of limitations for correcting qualified sick leave wages paid in 2021 expired on April 15, 2025, for most employers. For more information about the period of limitations, see Is There a Deadline for Filing Form 943-X, earlier.

Adjustments to the social security tax on qualified sick leave wages and qualified family leave wages for leave taken after March 31, 2020, and before April 1, 2021, are reported on Form 943©\X, lines 7 and 8, respectively. Adjustments to the nonrefundable portion of the credit for qualified sick and family leave wages for leave taken after March 31, 2020, and before April 1, 2021, are reported on Form 943©\X, line 14, and adjustments to the refundable portion of the credit are reported on Form 943©\X, line 23. Adjustments to qualified health plan expenses allocable to qualified sick leave wages and to qualified family leave wages for leave taken after March 31, 2020, and before April 1, 2021, are reported on Form 943©\X, lines 26 and 27, respectively. For corrections to a 2020 Form 943, the credit for qualified sick and family leave wages is only available for wages paid with respect to leave taken after March 31, 2020, and before January 1, 2021. If you claimed the credit for qualified sick and family leave wages for leave taken after March 31, 2020, and before April 1, 2021, on your original Form 943, and you make any corrections on Form 943©\X to amounts used to figure this credit, you¡¯ll need to refigure the amount of this credit using Worksheet 1. You¡¯ll also use this worksheet to figure this credit if you're claiming the credit for the first time on Form 943-X. For more information about the credit for qualified sick and family leave wages, go to IRS.gov/PLC.

Qualified sick leave wages paid with respect to leave taken after March 31, 2020, and before April 1, 2021, aren't subject to the employer share of social security tax; therefore, the tax rate on these wages is 6.2% (0.062). For more information about qualified sick leave wages, see Definition of qualified sick and family leave wages for leave taken after March 31, 2020, and before April 1, 2021 , later, and go to IRS.gov/PLC. If you're correcting the qualified sick leave wages you reported on Form 943, line 2a, enter the total corrected amount in column 1. In column 2, enter the amount you originally reported or as previously corrected. In column 3, enter the difference between columns 1 and 2.

Multiply the amount in column 3 by 0.062 and enter that result in column 4.

8. Qualified Family Leave Wages (For Leave Taken After March 31, 2020, and Before April 1, 2021)

Generally, the period of limitations for correcting qualified family leave wages paid in 2020 expired on April 15, 2024, for most employers. Generally, the period of limitations for correcting qualified family leave wages paid in 2021 expired on April 15, 2025, for most employers. For more information about the period of limitations, see Is There a Deadline for Filing Form 943-X, earlier.

Qualified family leave wages paid with respect to leave taken after March 31, 2020, and before April 1, 2021, aren't subject to the employer share of social security tax; therefore, the tax rate on these wages is 6.2% (0.062). For more information about qualified family leave wages, see Definition of qualified sick and family leave wages for leave taken after March 31, 2020, and before April 1, 2021 , later, and go to IRS.gov/PLC. If you're correcting the qualified family leave wages you reported on Form 943, line 2b, enter the total corrected amount in column 1. In column 2, enter the amount you originally reported or as previously corrected. In column 3, enter the difference between columns 1 and 2.

Multiply the amount in column 3 by 0.062 and enter that result in column 4.

Be sure to explain the reasons for this correction on line 41.

9. Wages Subject to Medicare Tax

If you¡¯re correcting the taxable Medicare wages you reported on Form 943, line 4, enter the total corrected amount in column 1. In column 2, enter the amount you originally reported or as previously corrected. In column 3, enter the difference between columns 1 and 2.

Multiply the amount in column 3 by 0.029 (2.9% tax rate) and enter that result in column 4.

10. Wages Subject to Additional Medicare Tax Withholding

You may use Form 943-X to correct errors to Additional Medicare Tax withholding for prior years if the amount reported on Form 943, line 7, isn¡¯t the amount you actually withheld. This type of error is an administrative error. The administrative error adjustment corrects the amount reported on Form 943 to agree with the amount actually withheld from employees.

You may also correct errors to Additional Medicare Tax withholding for prior years if section 3509 rates apply. If section 3509 rates apply, see the instructions for lines 16¨C19, later.

If a prior year error was a nonadministrative error, you may correct only the wages subject to Additional Medicare Tax withholding that were originally reported on Form 943, line 6, or previously corrected on Form 943-X. You can¡¯t correct the tax reported on Form 943, line 7.

You discovered both errors on March 13, 2025. Use Form 943-X, line 10, to correct the errors as shown.

Determine the portion of wages reported in column 3 that is related to the administrative error ($47,000 ? $20,000 (nonadministrative error) = $27,000 (administrative error)). Multiply this portion of column 3 by 0.009 (0.9% tax rate) to determine your tax correction.

11. Federal Income Tax Withheld

If you¡¯re correcting the federal income tax withheld from wages you reported on Form 943, line 8, enter the total corrected amount in column 1. In column 2, enter the amount you originally reported or as previously corrected. In column 3, enter the difference between columns 1 and 2.

Copy the amount in column 3 to column 4. Include any minus sign shown in column 3.

Generally, you may only correct administrative errors to federal income tax withholding (that is, errors in which the amount reported on Form 943, line 8, isn't the amount you actually withheld from an employee's wages) and errors for which section 3509 rates apply. Only transposition or math errors involving the inaccurate reporting of the amount withheld are ¡°administrative errors.¡± The administrative error adjustment corrects the amount reported on Form 943 to agree with the amount actually withheld from employees. See section 2 of Pub. 15 for more information about corrections during the calendar year and about administrative errors. If section 3509 rates apply, see the instructions for lines 16¨C19, later.

You can't file a Form 943-X to correct federal income tax withholding for prior years for nonadministrative errors. In other words, you can't correct federal income tax actually withheld from an employee in a prior year if you discover that you didn't withhold the right amount. For example, you can't correct federal income tax withheld in a prior year because you used the wrong income tax withholding table or you didn't treat a payment correctly as taxable or nontaxable. Similarly, if you paid federal income tax in a prior year on behalf of your employee rather than deducting it from the employee's pay (which resulted in additional wages subject to tax), and in a subsequent year you determine that you incorrectly calculated the amount of tax, you can't correct the federal income tax withholding.

12. Tax Adjustments

For purposes of these instructions, all references to ¡°sick pay¡± mean ordinary sick pay, not ¡°qualified sick leave wages.¡±

Don¡¯t enter an amount on line 12 unless you need to correct any adjustments reported on Form 943, line 10. Amounts reported on line 12 reflect corrections of amounts misstated on Form 943, line 10. See Example¡ªThird-party sick pay underreported , later.

Enter in column 1 the total corrected amount for Form 943, line 10. Enter in column 2 the total originally reported or previously corrected amount from Form 943, line 10. In column 3, enter the difference between columns 1 and 2.

You may need to report negative numbers in any column. Make sure that the difference you enter in column 3 accurately represents the change to adjustments originally reported or previously corrected on Form 943, line 10.

Copy the amount in column 3 to column 4. Include any minus sign shown in column 3.

On line 41, describe what you misreported on Form 943. Tell us if your adjustment is for fractions of cents, third-party sick pay, or group-term life insurance.

Only use line 12 to correct adjustments for fractions of cents, third-party sick pay, or group-term life insurance previously reported. File a separate Form 943-X for each year being corrected.

13. Qualified Small Business Payroll Tax Credit for Increasing Research Activities

The payroll tax credit election must be made on or before the due date of the originally filed income tax return (including extensions). Any election to take the payroll tax credit may be revoked only with the consent of the IRS.

If you're correcting the qualified small business payroll tax credit for increasing research activities that you reported on Form 943, line 12 (line 12a for years after 2019 and before 2024), enter the total corrected amount in column 1. In column 2, enter the amount you originally reported or as previously corrected. In column 3, enter the difference between columns 1 and 2.

Copy the amount in column 3 to column 4. However, to properly show the amount as a credit or balance due item, enter a positive number in column 3 as a negative number in column 4 or a negative number in column 3 as a positive number in column 4.

You must attach a corrected Form 8974 and explain the reasons for this correction on line 41.

16¨C19. Special Additions to Wages for Federal Income Tax, Social Security Taxes, Medicare Taxes, and Additional Medicare Tax

Section 3509 provides special rates for the employee share of social security tax, Medicare tax, Additional Medicare Tax, and federal income tax withholding when workers are reclassified as employees in certain circumstances. The applicable rate depends on whether you filed required information returns. An employer can¡¯t recover any tax paid under this provision from the employees. The full employer share of social security and Medicare taxes is due for all reclassifications.

On lines 16¨C19, enter only corrections to wages resulting from reclassifying certain workers as employees when section 3509 rates are used to calculate the taxes.

If the employer issued the required information returns, use the section 3509 rates as follows.

If the employer didn¡¯t issue the required information returns, use the section 3509 rates as follows.

Unlike some other lines on Form 943-X, enter in column 1 only the corrected wages for workers being reclassified, not the amount paid to all employees. Enter in column 2 previously reported wages (if any) to reclassified employees. To get the amount for column 4, use the applicable section 3509 rates. If you filed the required information returns for some employees but didn¡¯t file them for other employees, be sure to use the applicable rates for each employee when calculating the amounts in column 4 and show your calculations on line 41. The tax correction in column 4 will be a positive number if you increased the amount of wages you previously reported. See the instructions for line 40, later, for more information.

20. Subtotal

Combine the amounts on lines 6¨C19 of column 4 and enter the total on line 20.
