IRS Instruction 943 – IRS Forms, Instructions, Pubs 2026 – If you’re an agricultural employer, navigating tax obligations can be complex, but understanding IRS Form 943 is essential for compliance. This form, officially known as the Employer’s Annual Federal Tax Return for Agricultural Employees, allows you to report federal income tax withheld, as well as Social Security and Medicare taxes for your farmworkers. In this guide, we’ll break down the 2025 instructions, filing requirements, updates, and tips to ensure accurate submission. Whether you’re a farmer, rancher, or agribusiness owner, staying informed helps avoid penalties and streamlines your payroll process.
What is IRS Form 943?
IRS Form 943 is an annual tax return specifically designed for agricultural employers. It reports wages paid to farmworkers that are subject to Social Security tax (at 6.2% each for employee and employer, with a 2025 wage base of $176,100), Medicare tax (1.45% each, no wage limit), Additional Medicare Tax (0.9% on wages over $200,000), and federal income tax withholding. Unlike Form 941 for non-agricultural employers, Form 943 focuses on the unique needs of the agriculture sector, excluding household employees in private farm homes (which may be reported on Schedule H of Form 1040 instead).
This form ensures that both employee and employer portions of taxes are accounted for, helping fund social programs like retirement and healthcare. For more details on its purpose, refer to the official IRS guidelines.
Who Needs to File Form 943?
Not every agricultural employer is required to file Form 943. You must file if you paid wages to one or more farmworkers and met either of these tests in 2025:
- $150 Test: You paid cash wages of $150 or more to any single farmworker during the year.
- $2,500 Test: Your total cash and noncash wages to all farmworkers reached $2,500 or more.
Special rules apply for hand-harvest laborers earning less than $150 annually—consult IRS Publication 15 for exemptions. Once you file your first Form 943, you must continue annually, even if no taxes are due, until you submit a final return (by checking the box above line 1 and attaching payroll details). Aggregate filers, such as section 3504 agents or Certified Professional Employer Organizations (CPEOs), must identify themselves on the form and attach Schedule R.
If you’re unsure about your filing status, the IRS Agriculture Tax Center provides tailored resources.
