What Is IRS Form 943?

IRS Form 943 is the annual return for agricultural employers to report federal employment taxes on wages paid to farmworkers. It covers:

Social Security Tax: 6.2% each from employer and employee (12.4% total) on wages up to $176,100 per employee.
Medicare Tax: 1.45% each (2.9% total) on all wages, with no limit.
Additional Medicare Tax: 0.9% withholding on wages over $200,000 (employee-only; no employer match).
Federal Income Tax Withholding: From employees’ paychecks.

Unlike quarterly Form 941 for non-agricultural employers, Form 943 allows annual filing with semiweekly or monthly deposits. Use Form 943-A for optional monthly tax records, and Form 943-X to amend errors. Household farm employees can report here or on Schedule H (Form 1040). For 2025, electronic filing is encouraged via Modernized e-File (MeF), now including Form 943-X.

Who Needs to File IRS Form 943 in 2025?

File Form 943 if you employed farmworkers in 2025 and paid:

$150 Test: $150 or more in cash wages to any one farmworker for farmwork.
$2,500 Test: $2,500 or more in total cash and noncash wages to all farmworkers.

These apply separately per worker or group; special rules exempt certain hand-harvest laborers under $150. Once filed, report annually—even with zero taxes—until a final return. Exemptions include non-agricultural wages (use Form 941) or Puerto Rico employers (unless U.S. withholding applies).

Certified Professional Employer Organizations (CPEOs), section 3504 agents, and aggregate filers must file electronically with Schedule R (Form 943). H-2A visa workers: Withhold income tax optionally; no Social Security/Medicare if visa-related.
