What Is IRS Form 943-A?
IRS Form 943-A is a supplemental document used by agricultural employers to detail their federal tax liability on a semiweekly basis. It must be attached to Form 943 (Employer’s Annual Federal Tax Return for Agricultural Employees) or Form 943-X (Adjusted Employer’s Annual Federal Tax Return for Agricultural Employees or Claim for Refund) when applicable. The form focuses on taxes related to agricultural wages, including federal income tax withheld and both employer and employee shares of Social Security and Medicare taxes (including Additional Medicare Tax on wages over $200,000).
Unlike the monthly summary on Form 943, Form 943-A breaks down liabilities by specific pay dates throughout the year. This helps the IRS verify timely deposits and assess any failure-to-deposit (FTD) penalties if discrepancies arise. The form’s total liability (Line M) must match Line 13 on Form 943 after adjustments and nonrefundable credits.
Key related publications include Publication 51 (Circular A), Agricultural Employer’s Tax Guide, which provides broader deposit rules and examples.
Who Needs to File Form 943-A?
You must file Form 943-A if you are an agricultural employer classified as a semiweekly schedule depositor. This applies to employers who deposit taxes on Wednesdays and Fridays based on payroll dates.
- Semiweekly Depositors: If your tax liability is deposited semiweekly, attach Form 943-A to your Form 943.
- Threshold Trigger: Monthly depositors become semiweekly if they accumulate $100,000 or more in tax liability on any day within a month. This status lasts through the current year and the next, requiring Form 943-A for the entire period. The $100,000 threshold is calculated before nonrefundable credits.
- Exemptions: Do not file if your annual net tax liability (Form 943, Line 13) is less than $2,500. Also, skip Form 943-A if you’re a monthly depositor and complete Line 17 on Form 943 instead.
Only report taxes on agricultural wages—exclude nonfarm wages. For detailed deposit rules, refer to Section 11 of Publication 15 (Circular E) or the Instructions for Form 943.
When and How to File Form 943-A
Form 943-A is filed annually with Form 943, due by January 31 of the following year. For the 2025 tax year, the deadline is February 2, 2026, since January 31 falls on a Saturday. If you’ve made full deposits, you can file by February 10.
- Filing Method: Attach Form 943-A to Form 943 or Form 943-X. File electronically via the IRS e-file system for faster processing, or mail to the address listed in the Form 943 instructions based on your location.
- Amended Filing: If errors lead to FTD penalties, file an amended Form 943-A with Form 943-X to correct liabilities without changing the annual total. This may reduce penalties.

Step-by-Step Instructions for Filling Out IRS Form 943-A
Form 943-A is a two-page document with sections for header information and monthly liability grids. Here’s a breakdown:
- Header Section:
- Enter your Employer Identification Number (EIN) and name as shown on Form 943.
- Specify the calendar year (e.g., 2025).
- Monthly Liability Sections:
- Each month (January to December) has lines 1–31 for entering tax liabilities based on wage payment dates (not deposit or accrual dates).
- Calculate liability as: Federal income tax withheld + Employer/Employee Social Security (12.4% on wages) + Employer/Employee Medicare (2.9% on wages) + Additional Medicare Tax (0.9% on wages over $200,000).
- Sum each month’s liabilities on lines A–L (e.g., Line A for January total).
- Total Liability:
- Line M: Add lines A–L. This must equal Form 943, Line 13.
For the qualified small business payroll tax credit for increasing research activities (up to $500,000 for tax years after 2022), reduce liabilities on Form 943-A starting from the first applicable payroll. Apply to employer Social Security (up to $250,000 per quarter) first, then Medicare. Excess credits carry forward. Attach Form 8974 if claiming this credit.
Example of Filling Out Form 943-A
Suppose wages are paid on January 11 ($10,000 liability) and January 25 ($15,000 liability):
- Enter $10,000 on January Line 11.
- Enter $15,000 on January Line 25.
- Total for January (Line A): $25,000.
If a monthly depositor hits $100,000 on October 3, switch to semiweekly and detail all subsequent pay dates.
Common Mistakes to Avoid When Filing Form 943-A?
- Using deposit or accrual dates instead of wage payment dates.
- Mismatching Line M with Form 943, Line 13, often due to mishandling credits.
- Completing Form 943’s Line 17 when using Form 943-A.
- Failing to account for status changes from monthly to semiweekly.
- Reporting non-agricultural wages or adjustments from prior years.
Incomplete forms may trigger an averaged FTD penalty. Always double-check totals and consult Publication 51 for guidance.
