What's New  
Qualified small business payroll tax credit for in-  
creasing research activities. For tax years beginning  
before January 1, 2023, a qualified small business may  
elect to claim up to $250,000 of its credit for increasing  
research activities as a payroll tax credit. The Inflation  
Reduction Act of 2022 (the IRA) increases the election  
amount to $500,000 for tax years beginning after  
December 31, 2022. The payroll tax credit election must  
be made on or before the due date of the originally filed  
income tax return (including extensions). The portion of  
the credit used against payroll taxes is allowed in the first  
calendar quarter beginning after the date that the qualified  
small business filed its income tax return. The election  
and determination of the credit amount that will be used  
against the employer's payroll taxes are made on Form  
6765, Credit for Increasing Research Activities. The  
amount from Form 6765, line 44, must then be reported  
on Form 8974, Qualified Small Business Payroll Tax Credit  
for Increasing Research Activities.

For quarters beginning before January 1, 2023, the  
payroll tax credit can be used only against the employer  
share of social security tax for the quarter and any  
remaining credit is carried forward to the next quarter.  
Starting in the first quarter of 2023, the payroll tax credit is  
first used to reduce the employer share of social security  
tax up to $250,000 per quarter and any remaining credit  
reduces the employer share of Medicare tax for the  
quarter. Any remaining credit, after reducing the employer  
share of social security tax and the employer share of  
Medicare tax, is then carried forward to the next quarter.  
Form 8974 is used to determine the amount of the credit  
that can be used in the current quarter. Corrections to this  
credit are made on Form 943-X, line 13. If you make a  
correction to Form 943-X, line 13, you must attach a  
corrected Form 8974. For more information, see the

family leave wages for leave taken after March 31, 2021,  
and before October 1, 2021, and you make any

The COVID-19 related employee retention credit has  
expired. The employee retention credit enacted under  
the Coronavirus Aid, Relief, and Economic Security  
(CARES) Act and amended and extended by the Taxpayer  
Certainty and Disaster Tax Relief Act of 2020 was limited  
to qualified wages paid after March 12, 2020, and before  
July 1, 2021. The employee retention credit under section  
3134 of the Internal Revenue Code, as enacted by the  
ARP and amended by the Infrastructure Investment and  
Jobs Act, was limited to qualified wages paid after June  
30, 2021, and before October 1, 2021, unless the  
employer was a recovery startup business. An employer  
that was a recovery startup business could also claim the  
employee retention credit for qualified wages paid after  
September 30, 2021, and before January 1, 2022. For  
more information about the employee retention credit,  
including an eligibility checklist, frequently asked  
questions, information on identifying employee retention  
credit scam promotions, and directions on how to  
withdraw a previously filed claim for the employee  
retention credit, go to IRS.gov/ERC.  
Corrections to amounts reported on Form 943, lines  
12c, 14e, 20, and 21, for the employee retention credit are  
reported on Form 943-X, lines 15a, 24a, 28, and 29,  
respectively. However, how you figure the employee  
retention credit for qualified wages paid after March 12,  
2020, and before July 1, 2021, is different from how you  
figure the credit for qualified wages paid after June 30,  
2021, and before January 1, 2022. For corrections to  
qualified wages paid after June 30, 2021, you may need to  
complete line 37 to tell us if you're eligible for the  
employee retention credit solely because your business is  
a recovery startup business. For corrections to qualified  
wages paid after September 30, 2021, you may need to  
complete line 38 to tell us if you’re eligible for the  
employee retention credit solely because your business is  
a recovery startup business.  
Credit for COBRA premium assistance payments is  
limited to periods of coverage beginning on or after  
April 1, 2021, through periods of coverage beginning  
on or before September 30, 2021. Section 9501 of the  
ARP provides for COBRA premium assistance in the form  
of a full reduction in the premium otherwise payable by  
certain individuals and their families who elect COBRA  
continuation coverage due to a loss of coverage as the  
result of a reduction in hours or an involuntary termination  
of employment (assistance eligible individuals). This  
COBRA premium assistance was available for periods of  
coverage beginning on or after April 1, 2021, through  
periods of coverage beginning on or before September  
30, 2021. A premium payee was entitled to the COBRA  
premium assistance credit at the time an eligible individual  
elects coverage. Therefore, other than in rare  
corrections on Form 943-X to amounts used to figure this  
credit, you'll need to refigure the amount of this credit  
using Worksheet 3. You'll also use this worksheet to figure  
this credit if you’re claiming it for the first time on Form  
943-X. If you claimed the employee retention credit for  
wages paid after March 12, 2020, and before July 1, 2021,  
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 2. You'll also use  
this worksheet to figure this credit if you’re claiming it for  
the first time on Form 943-X. If you claimed the employee  
retention credit for wages paid after June 30, 2021, and  
before January 1, 2022, 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  
4. You'll also use this worksheet to figure this credit if  
you’re claiming it for the first time on Form 943-X. If you  
claimed the COBRA premium assistance credit 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 5. You'll also use this worksheet to  
figure this credit if you’re claiming it for the first time on  
Form 943-X.  
Reminders  
If a line on Form 943-X doesn't apply to you, leave  
it blank. If you're correcting a year before 2020,  
you must leave blank lines 7, 8, 14, 15a, 21, 22,  
TIP  
23, 24a, 26, 27, 28, 29, and 30. If you're correcting a year  
before 2021, you must leave blank lines 15b, 15c, 15d,  
24b, 24c, 31, 32, 33, 34, 35, 36, 37, and 38. If you're  
correcting a year after 2021, you must leave blank lines  
15a, 24a, 28, 29, 37, and 38.  
The COVID-19 related credit for qualified sick and  
family leave wages is limited to leave taken after  
March 31, 2020, and before October 1, 2021. The  
credit for qualified sick and family leave wages, as  
enacted under the Families First Coronavirus Response  
Act (FFCRA) and amended and extended by the  
COVID-related Tax Relief Act of 2020, is for leave taken  
after March 31, 2020, and before April 1, 2021, and the  
credit for qualified sick and family leave wages under  
sections 3131, 3132, and 3133 of the Internal Revenue  
Code, as enacted under the American Rescue Plan Act of  
2021 (the ARP), is for leave taken after March 31, 2021,  
and before October 1, 2021. For more information about  
the credit for qualified sick and family leave wages, go to  
Corrections to amounts reported on Form 943, lines 2a,  
2b, 12b, 14d, 18, and 19, for 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, lines 7, 8, 14, 23, 26, and 27, respectively.  
Corrections to amounts reported on Form 943, lines  
12d, 14f, 22, 23, 24, 25, 26, and 27, for the credit for  
qualified sick and family leave wages for leave taken after  
March 31, 2021, and before October 1, 2021, are reported  
circumstances, due to the COBRA notice and election  
period requirements (generally, employers have 60 days  
to provide notice and assistance eligible individuals have  
60 days to elect coverage), January 2022 was generally  
the end of the period in which an assistance eligible  
individual would have elected coverage. Under some rare  
circumstances, it may be possible for a premium payee to  
2
Instructions for Form 943-X (Rev. 2-2024)  
   
become entitled to the COBRA premium assistance credit  
after January 2022. In these rare instances, the credit is  
still claimed on Form 943 filed for 2022 and an  
adjustment, if needed, can be made on Form 943-X for  
2022. Employers eligible to claim the COBRA premium  
assistance credit after 2022 must file Form 943-X to claim  
the credit.  
Only transposition or math errors involving the  
inaccurate reporting of the amount actually  
withheld are administrative errors.  
!
CAUTION  
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  
For more information on COBRA premium assistance  
payments and the credit, see Notice 2021-31, 2021-23  
I.R.B. 1173, available at IRS.gov/irb/

Corrections to amounts reported on Form 943, lines

credit are reported on Form 943-X, lines 15c, 15d, and

withholding. However, you must still make any necessary  
corrections to the amount of wages you reported on Form  
943 and Form W-2, Wage and Tax Statement, for a prior  
year by filing Form 943-X and Form W-2c, Corrected  
Wage and Tax Statement, respectively.  
Payroll tax credit for certain tax-exempt organiza-  
tions affected by qualified disasters. Section 303(d) of  
the Taxpayer Certainty and Disaster Tax Relief Act of 2020  
allows for a payroll tax credit for certain tax-exempt  
organizations affected by certain qualified disasters not  
related to COVID-19. This credit is claimed on Form  
5884-D. If applicable to the year that you're correcting,  
you'll enter the credit claimed on Form 5884-D on  
Worksheet 1 to figure your credit for qualified sick and  
family leave wages for leave taken before April 1, 2021, or  
Worksheet 2 to figure the employee retention credit for  
wages paid after March 12, 2020, and before July 1, 2021.  
For more information about this credit, go to IRS.gov/  
The amount actually withheld is reflected on  
payroll information or on Form W-2, which can be  
used by the employee to claim a credit for  
TIP  
withholding for individual income tax return purposes.  
Correcting Additional Medicare Tax withholding and  
wages subject to Additional Medicare Tax withhold-  
ing. Wages subject to Additional Medicare Tax  
withholding are reported on Form 943, line 6. Certain  
errors discovered on a previously filed Form 943 are  
corrected on Form 943-X, line 10. However, you can't file a  
Form 943-X to correct the wrong amount of Additional  
Medicare Tax actually withheld from an employee in a  
prior year, including any amount you paid on behalf of your  
employee rather than deducting it from the employee's  
pay (which resulted in additional wages subject to tax).  
See the instructions for line 10, later, for more information  
on the types of errors that can be corrected and how the  
correction is reported on Form 943-X. For more  
information about Additional Medicare Tax withholding,  
see the Instructions for Form 943 or go to IRS.gov/  
You may need to attach Schedule R (Form 943) to  
your Form 943-X. If you were required to file Schedule R  
(Form 943), Allocation Schedule for Aggregate Form 943  
Filers, when you filed Form 943, you must complete  
Schedule R (Form 943) when correcting an aggregate  
Form 943. Schedule R (Form 943) is completed only for  
those clients and customers who have corrections  
reported on Form 943-X. Schedule R (Form 943) is filed  
as an attachment to Form 943-X.  
Employee consents to support a claim for refund.  
Rev. Proc. 2017-28, 2017-14 I.R.B. 1061, available at  
guidance to employers on the requirements for employee  
consents used by an employer to support a claim for  
refund of overcollected social security tax and Medicare  
tax. The revenue procedure clarifies the basic  
requirements for both a request for employee consent and  
for the employee consent, and permits a consent to be  
requested, furnished, and retained in an electronic format  
as an alternative to a paper format. The revenue  
procedure also contains guidance concerning when an  
employer may claim a refund of only the employer share of  
overcollected social security tax and Medicare tax. The  
revenue procedure requires that any request for consent  
include an Additional Medicare Tax notice indicating that  
any claim on the employees’ behalf won’t include a claim  
for overpaid Additional Medicare Tax.  
Correcting federal income tax withheld. 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. See section 13 of Pub. 15,  
Employer's Tax Guide, for more information about  
corrections during the calendar year and about  
Approved section 3504 agents and certified  
professional employer organizations (CPEOs) must  
complete and file Schedule R (Form 943) when filing an  
aggregate Form 943. Aggregate Forms 943 are filed by  
agents approved by the IRS under section 3504. To  
request approval to act as an agent for an employer, the  
agent files Form 2678 with the IRS. Aggregate Forms 943  
are also filed by CPEOs approved by the IRS under  
section 7705. To become a CPEO, the organization must  
administrative errors. See section 2 of Pub. 15 for more  
information about section 3509. If section 3509 rates  
apply, see the instructions for lines 16–19, later.

apply through the IRS Online Registration System at  
IRS.gov/CPEO. CPEOs file Form 8973, Certified  
Professional Employer Organization/Customer Reporting  
Agreement, to notify the IRS that they started or ended a  
service contract with a customer.  
We use the terms “correct” and “corrections” on  
Form 943-X and in these instructions to include  
interest-free adjustments under sections 6205 and  
TIP  
6413 and claims for refund and abatement under sections  
6402, 6414, and 6404. See Rev. Rul. 2009-39 for  
examples of how the interest-free adjustment and claim  
for refund rules apply in 10 different situations. You can  
find Rev. Rul. 2009-39, 2009-52 I.R.B. 951, at IRS.gov/irb/  
Other third-party payers that file aggregate Forms 943,  
such as non-certified PEOs, must complete and file  
Schedule R (Form 943) if they have clients that are  
claiming the qualified small business payroll tax credit for  
increasing research activities, the credit for qualified sick  
and family leave wages, the employee retention credit,  
and/or the COBRA premium assistance credit, or clients  
deferring the employer or the employee share of social  
security tax. If you're an other third-party payer that didn't  
file Schedule R (Form 943) with Form 943 because you  
didn't meet these requirements, but are now filing Form  
943-X to report these credits or the deferral of the  
employer or the employee share of social security tax for  
your clients, then you must now file Schedule R (Form  
943) and attach it to Form 943-X.  
When you discover an error on a previously filed Form  
943, you must:  
Correct that error using Form 943-X;  
File a separate Form 943-X for each Form 943 that  
you’re correcting; and  
Generally, file Form 943-X separately. Don’t file Form  
943-X with Form 943. However, if you didn't previously file  
Form 943 because you mistakenly treated your employees  
as nonemployees, you may have to file Form 943-X with  
Form 943. See the instructions for line 40, later.  
If you didn’t file a Form 943 for 1 or more years for  
which you should have filed Form 943, don’t use Form  
943-X. Instead, file Form 943 for each of those years.  
Also, see When Should You File Form 943-X, later.  
However, if you didn’t file Form(s) 943 because you  
improperly treated workers as independent contractors or  
nonemployees and are now reclassifying them as  
employees, see the instructions for line 40, later.

adjustments to Form 943, lines 2a, 2b, 12b, 14d, 18, and  
19;  
overreported tax amounts for the same year on a single  
Form 943-X, unless you’re requesting a refund or  
abatement. If you’re requesting a refund or abatement and  
you’re correcting both underreported and overreported tax  
amounts, file one Form 943-X correcting the

employment taxes and are making a payment, or if you  
overreported employment taxes and will be applying the  
credit to Form 943 for the period during which you file  
Form 943-X. However, see the Caution under Is There a  
Deadline for Filing Form 943-X, later, if you’re correcting  
overreported tax amounts during the last 90 days of a  
period of limitations. You’ll use the claim process if you  
overreported employment taxes and are requesting a  
refund or abatement of the overreported tax amount.  
Follow the chart on page 6 of Form 943-X for help in  
choosing whether to use the adjustment process or the  
claim process. Be sure to give us a detailed explanation  
on line 41 for each correction that you show on Form  
943-X.

Form 943-X as filed on time if the envelope containing  
Form 943-X is properly addressed, contains sufficient  
postage, and is postmarked by the U.S. Postal Service on  
or before the due date, or sent by an IRS-designated  
private delivery service (PDS) on or before the due date. If  
you don’t follow these guidelines, we will consider Form  
943-X filed when it is actually received. See Pub. 15 for  
more information on legal holidays. For more information  
later.  
Underreported tax. If you’re correcting underreported  
tax, you must file Form 943-X by the due date of the return  
for the return period in which you discovered the error  
(January 31 of the following year) and pay the amount you  
owe by the time you file. Doing so will generally ensure  
that your correction is interest free and not subject to  
failure-to-pay (FTP) or failure-to-deposit (FTD) penalties.  
See What About Penalties and Interest, later. For details  
on how to make a payment, see the instructions for  
line 25, later.  
If Form 943-X is filed late (after the due date of the  
return for the return period in which you discovered the  
error), you must attach an amended Form 943-A to Form  
943-X. Otherwise, the IRS may assess an “averaged” FTD  
penalty. See “Averaged” FTD penalty in section 11 of Pub.  
15 for more information about “averaged” FTD penalties.  
The total tax reported on Form 943-A, line M, must match  
the corrected tax (Form 943, line 13, combined with any  
correction reported on Form 943-X, line 20) for the year,  
less any previous abatements and interest-free tax  
assessments.  
Example—You owe tax. On February 16, 2024, you  
discovered that you underreported $1,000 of social  
security and Medicare wages on your 2023 Form 943. File  
Form 943-X and pay the amount you owe by January 31,  
2025, because you discovered the error in 2024 and  
January 31, 2025, is the due date for that year. If you file  
Form 943-X before January 31, 2025, pay the amount you  
owe by the time you file.  
You have additional requirements to complete when  
filing Form 943-X, such as certifying that you filed (or will  
file) all applicable Forms W-2 and Forms W-2c. For  
corrections of overreported federal income tax, social  
security tax, Medicare tax, or Additional Medicare Tax,  
you must make any certifications that apply to your  
situation.  
Don’t use Form 943-X to correct Form CT-1, 941,  
941-SS, 944, or 945. Instead, use the “X” form  
!
CAUTION  
that corresponds to those forms (Form CT-1 X,  
941-X, 944-X, or 945-X).

Generally, you may correct overreported taxes on a  
previously filed Form 943 if you file Form 943-X within 3  
years of the date Form 943 was filed or 2 years from the  
date you paid the tax reported on Form 943, whichever is  
later. You may correct underreported taxes on a previously  
filed Form 943 if you file Form 943-X within 3 years of the  
date the Form 943 was filed. We call each of these time  
frames a period of limitations. For purposes of the period  
of limitations, Form 943 is considered filed on April 15 of  
the succeeding calendar year if filed before that date.  
Example. You filed your 2020 Form 943 on January  
28, 2021, and payments were timely made. The IRS treats  
the return as if it were filed on April 15, 2021. On January  
24, 2024, you discovered that you overreported social  
security and Medicare wages on that form by $350. To  
correct the error, you must file Form 943-X by April 15,  
2024, and use the claim process.  
PDSs can't deliver to P.O. boxes. You must use the U.S.

Overview of the Process  
To correct a previously filed Form 943, use Form 943-X to  
file either an adjusted employment tax return or a claim for  
refund or abatement. The adjustment process and the  
claim process are outlined below.  
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.  
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).  
Example—You underreported employment taxes.  
On June 18, 2024, you discovered an error that results in  
additional tax on your 2023 Form 943. File Form 943-X by  
January 31, 2025, and pay the amount you owe by the  
time you file. See When Should You File Form 943-X,  
earlier. Don’t attach Form 943-X to your 2024 Form 943.  
If you overreported the tax. If you overreported the  
tax on a previously filed Form 943, choose one of the  
following options.  
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.  
Use the adjustment process. Check the box on line 1 to  
apply any credit (negative amount) from line 25 to Form  
943 for the year during which you file Form 943-X.  
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.  
Use the claim process. Check the box on line 2 to file a  
claim on Form 943-X requesting a refund or abatement of  
the amount shown on line 25.

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 below.

2. Claim  
Specific Instructions:  
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.  
Part 1: Select ONLY One Process  
Because Form 943-X may be used to file either an  
adjusted employment tax return or a claim for refund or  
abatement, you must check one box on either line 1 or  
line 2. Don’t check both boxes.  
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  
Correcting an employment tax credit or social securi-  
ty tax deferral. For lines 1 and 2, if you underreported an  
employment tax credit or the amount of social security tax  
deferred, treat it like you overreported a tax amount. If you  
overreported an employment tax credit or the amount of  
social security tax deferred, treat it like you underreported  
a tax amount. If you're filing Form 943-X to adjust only an  
employment tax credit and/or the amount of social  
security tax deferred and you're not correcting any  
overreported taxes on Form 943-X, lines 6–11, skip lines 4  
and 5.  
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.  
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.  
You may not file a refund claim to correct federal  
income tax or Additional Medicare Tax actually

CAUTION  
withheld from employees.  
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.  
Part 2: Complete the Certifications  
You must complete all certifications that apply by checking  
the appropriate boxes. If all of your corrections relate to  
underreported tax amounts, complete line 3 only; skip  
lines 4 and 5 and go to Part 3. If your corrections relate to  
overreported tax amounts, other than corrections related  
to underreported employment tax credits and social  
security tax deferrals, you have a duty to ensure that your  
employees' rights to recover overpaid employee social  
security and Medicare taxes that you withheld are  
protected. The certifications on lines 4 and 5 address the  
requirement to:  
Form 943-X can't be used to correct overreported  
amounts of Additional Medicare Tax unless the

CAUTION  
amounts weren’t withheld from employee wages.  
If you owe tax. Pay the amount shown on line 25 by the  
time you file Form 943-X. Generally, you won’t be  
charged interest if you file on time, pay on time, enter the  
date you discovered the error, and explain the correction  
on line 41.  
If you have a credit. You overreported employment  
taxes (you have a negative amount on line 25) and want  
the IRS to apply the credit on Form 943 for the period  
during which you filed Form 943-X. The IRS will apply your  
credit on the first day of the Form 943 year during which  
you filed Form 943-X. However, the credit you show on  
Form 943-X, line 25, may not be fully available on your  
Form 943 if the IRS corrects it during processing or you  
owe other taxes, penalties, or interest. The IRS will notify  
you if your claimed credit changes or if the amount  
available as a credit on Form 943 was reduced because of  
unpaid taxes, penalties, or interest.  
Repay or reimburse your employees for the  
overcollection of employee social security and Medicare  
taxes, or

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. Unless otherwise  
noted, references on Form 943-X and throughout these  
instructions to Form W-2 include Forms W-2AS, W-2CM,  
W-2GU, W-2VI, and 499R-2/W-2PR; references to Form  
W-2c include Form 499R-2c/W-2cPR; references to Form  
W-3 include Form W-3SS and Form W-3PR; and  
references to Form W-3c include Form W-3C (PR).  
Don’t check the box on line 1 if you’re correcting  
overreported tax amounts and the period of

Forms W-2 or Forms W-2c even if your corrections on  
Form 943-X don’t change amounts shown on those forms.

Instructions for Form 943-X (Rev. 2-2024)  
       
For example, if your only correction to Form 943 involves  
misstated tax adjustments, which don't impact the  
amounts reported on your employee's Form 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.  
You may not file a refund claim to correct the  
incorrect amount of federal income tax or  
Additional Medicare Tax actually withheld from

CAUTION  
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.  
4. Certifying Overreporting Adjustments  
5a. Check the box on line 5a if your overreported tax  
includes each affected employee share of prior year social  
security and Medicare taxes. You’re certifying that you  
repaid or reimbursed to the employees their share of prior  
year social security and Medicare taxes and you received  
written statements from those employees stating that they  
didn’t and won’t receive a refund or credit for the prior year  
taxes. Don't send these statements to the IRS. Keep them  
for your records. Generally, all employment tax records  
must be kept for at least 4 years. Records related to  
qualified sick leave wages and qualified family leave  
wages for leave taken after March 31, 2021, and before  
October 1, 2021, and records related to qualified wages  
for the employee retention credit paid after June 30, 2021,  
should be kept for at least 6 years. Copies must be  
submitted to the IRS if requested.  
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  
!
CAUTION  
unless the amounts weren’t withheld from  
employee wages.  
5b. Check the box on line 5b if your overreported tax  
includes each affected employee share of prior year social  
security and Medicare taxes and you haven’t yet repaid or  
reimbursed the employee share of taxes. You’re certifying  
that you received consent from each affected employee to  
file a claim on the employee share of those taxes and you  
received written statements from those employees stating  
that they didn’t and won’t receive a refund or credit for the  
prior year taxes.  
4a. Check the box on line 4a if your overreported amount  
includes each affected employee share of overcollected  
taxes. You’re certifying that you repaid or reimbursed the  
employee share of prior year taxes and you received  
written statements from the employees stating that they  
didn’t and won’t receive a refund or credit for the prior year  
taxes. Don’t send these statements to the IRS. Keep them  
for your records. Generally, all employment tax records  
must be kept for at least 4 years. Records related to  
qualified sick leave wages and qualified family leave  
wages for leave taken after March 31, 2021, and before  
October 1, 2021, and records related to qualified wages  
for the employee retention credit paid after June 30, 2021,  
should be kept for at least 6 years. Copies must be  
submitted to the IRS if requested.  
An employee consent must:  
Contain the name, address, and social security number  
(or truncated taxpayer identification number, when  
appropriate) of the employee;  
Contain the name, address, and EIN of the employer;  
Contain the tax period(s), the type of tax, and the  
amount of tax for which the consent is provided;

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.

for the employee share of social security and Medicare  
taxes, they couldn’t be found, or they didn’t give you a  
statement described on line 5b.

of tax on a decrease to social security wages, use 0.062  
(6.2%) when multiplying the amount shown in column 3. If  
you’re correcting both shares of tax for some employees  
and only the employer share for other employees, enter  
the properly calculated amount in column 4. Be sure to  
show your calculations on line 41.

you included $2,000 in social security wages for one of  
your employees twice. To correct the error, figure the  
difference on Form 943-X as shown below.  
What Amounts Should You Report in Part 3?  
On lines 6–11, 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

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

you’ll need to make a correction on Form 943-X, lines 6  
and 7, and enter the properly calculated amount in column  
4 for each line.  
Example—Qualified sick leave wages increased.  
You paid $2,000 of qualified sick leave wages to only one  
of your employees on March 26, 2021. In March 2024, you  
discover that you only reported $1,000 of qualified sick  
leave wages on your 2021 Form 943. To correct the error,  
figure the difference on Form 943-X as shown below.  
If the amount in column 3 used a minus sign,  
also use a minus sign in column 4.  
Note. If you erroneously reported qualified family leave  
wages for leave taken after March 31, 2020, and before  
April 1, 2021, on Form 943, line 2, instead of on line 2b,  
you’ll need to make a correction on Form 943-X, lines 6

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

administrative error adjustment corrects the amount  
reported on Form 943 to agree with the amount actually  
withheld from employees.

of tax on a decrease to Medicare wages, use 0.0145  
(1.45%) when multiplying the amount in column 3. If you’re  
correcting both shares of tax for some employees and  
only the employer share for other employees, enter the  
properly calculated amount in column 4. Be sure to

2 months of work in September 2023. You withheld $400  
of federal income tax at the time you paid Jack. These

employment in October 2023 (after only 1 month of  
service). In February 2024, Jack repaid $2,000 to you for  
the 1 month he didn't work. You can't file Form 943-X to  
reduce the federal income tax withheld because you  
actually withheld the federal income tax from wages. You  
also can't file Form 943-X to reduce wages because the

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

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

deposits, go to IRS.gov/ETD and see the Instructions for  
Form 943, available at IRS.gov/Form943.  
21. Deferred Amount of the Employer Share of  
Social Security Tax  
Use Form 943-X, line 21, if you need to correct the  
deferred amount of the employer share of social security  
tax that you reported on your 2020 Form 943, line 14b.  
Enter the total corrected amount in column 1. In column 2,  
enter the amount you originally reported or as previously  
corrected by you or the IRS. In column 3, enter the  
difference between columns 1 and 2.  
Be sure to explain the reasons for any correction on  
line 41.  
22. Deferred Amount of the Employee Share of  
Social Security Tax  
Use Form 943-X, line 22, if you need to correct the  
deferred amount of the employee share of social security  
tax that you reported on your 2020 Form 943, line 14c.  
Enter the total corrected amount in column 1. In column 2,  
enter the amount you originally reported or as previously  
corrected by you or the IRS. In column 3, enter the  
difference between columns 1 and 2.  
Copy the amount in column 3 to column 4. However,  
because an increase to the deferred amount of the  
employer share of social security tax defers the payment  
due, to properly show the amount as a deferral of  
payment, enter a positive number in column 3 as a  
negative number in column 4. A decrease to the deferred  
amount of the employer share of social security tax  
decreases the payment you can defer and must be shown  
as a balance due item; therefore, to properly show the  
amount as a balance due item, enter a negative number in  
column 3 as a positive number in column 4.  
If you're filing Form 943-X to increase the amount of  
social security wages paid on or after March 27, 2020,  
and before January 1, 2021, so that there is an additional  
amount of social security tax that hasn't yet been paid,  
and hasn't yet been deferred, then you may use Form  
943-X to increase the amount of the deferred employer  
share of social security tax originally reported on Form  
943, line 14b. If you're filing Form 943-X to decrease the  
amount of social security wages paid on or after March  
27, 2020, and before January 1, 2021, so that there is a  
decrease in the amount of social security tax that is  
eligible for deferral, then you must use Form 943-X to  
decrease the amount of the deferred employer share of  
social security tax originally reported on Form 943,  
line 14b, if the decrease in wages causes the amount you  
originally deferred to exceed the amount that is now  
eligible for deferral. Otherwise, you may only correct the  
amount of the deferred employer share of social security  
tax if the amount originally reported on Form 943, line 14b,  
isn't the amount you actually deferred (for example, you  
incorrectly reported the amount that you actually  
Copy the amount in column 3 to column 4. However,  
because an increase to the deferred amount of the  
employee share of social security tax defers the payment  
due, to properly show the amount as a deferral of  
payment, enter a positive number in column 3 as a  
negative number in column 4. A decrease to the deferred  
amount of the employee share of social security tax  
decreases the payment you can defer and must be shown  
as a balance due item; therefore, to properly show the  
amount as a balance due item, enter a negative number in  
column 3 as a positive number in column 4.  
You may only correct the amount of the deferred  
employee share of social security tax if the amount  
originally reported on Form 943, line 14c, isn't the amount  
you actually deferred (for example, you incorrectly  
reported the amount that you actually deferred). If you  
already paid the correct amount of the employee's share  
of social security tax, you may not subsequently defer the  
payment by filing Form 943-X.  
The deferred amount of the employee share of social  
security tax was only available for social security wages of  
less than $4,000 paid to an employee in any biweekly pay  
period (or the equivalent threshold amount for other pay  
periods) paid on a pay date during the period beginning  
on September 1, 2020, and ending on December 31,  
2020. The due date for withholding and payment of the  
deferred employee share of social security tax was  
postponed until the period beginning on January 1, 2021,  
and ending on December 31, 2021. The employer was  
liable to pay the deferred employee share of social  
security tax to the IRS and was required to do so before  
January 1, 2022, to avoid interest, penalties, and additions  
to tax on those amounts. Because January 1, 2022, was a  
nonbusiness day, payments made on January 3, 2022,  
were considered timely. For more information about the  
deferral of the employee share of social security tax, see  
Notice 2020-65, 2020-38 I.R.B. 567, available at  
deferred). If you already paid the correct amount of the  
employer share of social security tax during the payroll tax  
deferral period, you may not subsequently defer the  
payment by filing Form 943-X. See IRS.gov/ETD for more  
information about the interaction of credits and the deferral  
of employment tax deposits and payments.  
The deferred amount of the employer share of social  
security tax was only available for deposits and payments  
due on or after March 27, 2020, and before January 1,  
2021, as well as deposits and payments due after January  
1, 2021, that were required for wages paid during the  
applicable period. One-half of the deferred amount of the  
employer share of social security tax was due by  
2021-11, 2021-06 I.R.B. 827, available at IRS.gov/irb/  
December 31, 2021, and the remainder was due by  
December 31, 2022. Because both December 31, 2021,  
and December 31, 2022, were nonbusiness days,  
payments made on the next business day were

If you owe tax and are filing a timely Form 943-X, don’t  
file an amended Form 943-A unless you were assessed

Form 943 and the amount of advance payments issued,  
the IRS will generally correct the amount reported on Form
