What IRS Form 943 (2021) Is For

Form 943 is the annual federal tax return specifically designed for employers who paid wages to one or more agricultural (farm) workers during 2021 and those wages were subject to Social Security and Medicare taxes or federal income tax withholding (IRS Instructions for Form 943 (2021)). This form is used exclusively for reporting employment taxes on farm labor—if you also employed non-agricultural workers, their taxes must be reported separately on Form 941 or Form 944.

When You'd Use Form 943 for 2021 (Late or Amended Filing)

You would file Form 943 for 2021 as a late return if you never filed the original form by its January 31, 2022 deadline (or February 10, 2022 if all deposits were made timely). Common scenarios for late filing include receiving IRS notices demanding the unfiled return, discovering you owed employment taxes that were never reported, or learning you had agricultural employees whose wages should have been reported. For amended returns, you'd use Form 943-X to correct errors on a previously filed 2021 Form 943, such as incorrect wage amounts, tax calculations, or to claim COVID-related employment tax credits that were available during 2021. The refund statute of limitations generally allows corrections within 3 years of the original filing date or 2 years from when taxes were paid, whichever is later (IRS Instructions for Form 943-X (2021)).

Key Rules Specific to 2021

The 2021 tax year included several unique provisions not available in other years. COVID-related employment tax credits were available, including the Employee Retention Credit for qualified wages paid before July 1, 2021 and after June 30, 2021 (with different rules), and credits for qualified sick and family leave wages for leave taken before April 1, 2021 and after March 31, 2021. The employer share Social Security tax deferral from 2020 required partial payment by December 31, 2021. Additionally, 2021 was the final year for certain COVID-related payroll tax deferrals and credits that aren't available for subsequent tax years (IRS Instructions for Form 943 (2021)).

Step-by-Step (High Level)

• Gather tax transcripts: Obtain wage and income transcripts from the IRS to understand what employment tax information they have on file for your business for 2021
• Complete Form 943 (2021): Use the specific 2021 version of the form, ensuring you report all agricultural wages, calculate Social Security and Medicare taxes correctly, and claim any applicable COVID-related credits
• Attach required schedules: Include Form 943-A if you were a semiweekly depositor, and any worksheets for employment tax credits if applicable
• File appropriately: Mail to the correct IRS processing center based on your location, or file electronically if you meet e-filing requirements
• Keep detailed records: Maintain copies of the return, all supporting documentation, and proof of filing for at least 4 years

Common Mistakes and How to Avoid Them

• Mixing farm and non-farm employees: Only report agricultural workers on Form 943—non-farm employees must be reported on Form 941 or Form 944, even if they work for the same employer
• Incorrect wage base applications: Ensure you apply the correct 2021 Social Security wage base limit of $142,800 and understand that Medicare taxes have no wage limit
• Missing deposit requirements: If your annual tax liability was $2,500 or more, you must make electronic deposits throughout the year according to monthly or semiweekly schedules—you can't wait to pay with the return
• Forgetting Forms W-2: You must issue Forms W-2 to employees and file them with the Social Security Administration, and any corrections require Forms W-2c
• Deposit schedule errors: Understand whether you're a monthly or semiweekly depositor based on your prior year tax liability, and note that accumulating $100,000 in tax liability on any day triggers next-day deposit requirements
• COVID credit calculation errors: If claiming 2021 employment tax credits, ensure you use the correct worksheets and understand that wages can't be counted for both Employee Retention Credit and PPP loan forgiveness

What Happens After You File

Processing times for late returns typically take 6-8 weeks, though amended returns may take longer. The IRS will send notices acknowledging receipt and may request additional documentation. If you owe taxes, penalties, and interest will be calculated from the original due date. Payment options include immediate payment, installment agreements using Form 9465, or offers in compromise in qualifying situations. If the IRS disagrees with your return, you'll receive a notice explaining proposed changes and have appeal rights, including the right to request an examination conference or file a formal appeal with the Office of Appeals (IRS.gov).

FAQs

Can I still file Form 943 for 2021 even though it's late?

Yes, you should file as soon as possible. While penalties and interest will apply, filing late is better than not filing at all, and you may qualify for penalty relief if you have reasonable cause.

What penalties apply to late-filed Form 943?

Penalties include failure-to-file (5% per month up to 25%), failure-to-pay (0.5% per month), and potentially failure-to-deposit penalties. Interest accrues on all unpaid amounts from the original due date (IRS Instructions for Form 943 (2021)).

Should I get transcripts before filing a late return?

Yes, obtain wage and income transcripts to see what information the IRS already has, which helps ensure your late return is complete and accurate.

How long do I have to claim a refund for overpaid 2021 taxes?

If I file Form 943-X, do I need to amend state returns?

Check with your state tax agency, as requirements vary by state. Some states require amended returns when federal employment tax returns are corrected.

Can I e-file a late Form 943 for 2021?

Electronic filing options may be limited for prior-year returns. Check with your tax software provider or payroll service, or file by mail using the addresses in the 2021 instructions.

What if I discover errors after filing my late return?

Use Form 943-X to correct any errors on your filed Form 943. File Form 943-X within the statute of limitations period to preserve your rights to credits or refunds.
