Agricultural Employer Tax Rules: FICA, FUTA, and Form 943

If you hire help on a farm, federal agricultural employer tax rules set higher wage and worker thresholds than the rules for other businesses. Social Security and Medicare (FICA) taxes and income tax withholding kick in once any single worker earns $150 or more in cash wages during the year, or once your total spending on farm labor reaches $2,500. Federal unemployment tax (FUTA) doesn’t apply until you pay $20,000 in cash wages in a quarter or employ at least ten workers on 20 different weeks. Cross any of those lines and a set of specific forms, deposit schedules, and penalties follows.

Work That Qualifies as Agricultural Labor

The special thresholds only apply if the work fits the federal tax code’s definition of agricultural labor. That covers work performed on a farm in connection with cultivating soil, raising crops, or harvesting agricultural or horticultural commodities. It also covers caring for livestock, poultry, bees, and fur-bearing animals, and operating or maintaining irrigation ditches, canals, and reservoirs used exclusively for farming.¹

Post-harvest handling like drying, packing, grading, or processing a commodity in its raw state qualifies too, but only if you produced more than half of that commodity yourself during the relevant period.¹ Work that doesn’t fit the definition falls under the standard employment tax thresholds, which are generally lower.

Social Security and Medicare Tax Thresholds

Two independent tests determine whether you owe FICA on farmworker pay. Either one, on its own, creates the obligation.

The $150 individual wage test: if you pay any single worker $150 or more in cash wages during the calendar year, that worker’s wages are subject to FICA. It’s tracked per employee, so one worker crossing $150 can trigger the tax even if your total payroll is small.
The $2,500 group test: if your total spending on agricultural labor reaches $2,500 or more during the year, every dollar of cash wages you paid becomes subject to FICA, including wages to workers who individually earned less than $150.

The group test counts both cash and noncash compensation, such as the value of room and board, when measuring whether you’ve hit $2,500.² Only cash wages are actually taxed once the threshold is met. Noncash payments to farmworkers aren’t themselves subject to FICA.³ A farm that pays $2,000 in cash plus $600 worth of housing has crossed the $2,500 line and owes FICA on the $2,000 in cash, even though neither the housing nor any individual worker might have triggered the tax alone.

When FICA applies, employer and employee each owe 6.2% for Social Security and 1.45% for Medicare. In 2026 the Social Security portion applies only to the first $184,500 of each worker’s earnings; there is no cap on the Medicare portion.⁴

Hand-Harvest Laborer Exception

One narrow carve-out from the $2,500 group test covers a specific kind of worker: a hand-harvest laborer paid on a piece-rate basis, who commutes daily from a permanent residence, and who worked in agriculture fewer than 13 weeks during the prior year. That worker is evaluated only under the $150 individual test.⁵ All three conditions must be met. A migrant worker traveling between farms wouldn’t qualify, even on piece-rate pay.

Federal Income Tax Withholding

Income tax withholding for farmworkers follows the same two triggers as FICA. Once you cross either the $150 individual threshold or the $2,500 group threshold, the cash wages that become subject to FICA also become subject to federal income tax withholding.² Below those thresholds there’s no mandatory withholding, though you and a worker can agree to voluntary withholding through a Form W-4.

Federal Unemployment Tax Thresholds

FUTA thresholds for farms are far higher than for other businesses, where the trigger is $1,500 in any quarter or one employee for 20 weeks.⁶ You become liable for FUTA on farm wages only if you meet one of these:

The $20,000 quarterly wage test: you paid $20,000 or more in cash wages for agricultural labor during any calendar quarter of the current or preceding year.
The 10-worker/20-week test: you employed at least 10 individuals in agricultural labor for some part of a day on each of 20 different weeks during the current or preceding year. The weeks don’t need to be consecutive, and the workers don’t need to be the same people from week to week.

Because both tests look at the current and immediately preceding year, crossing either threshold in one year carries the obligation into the next.⁷

The gross FUTA rate is 6.0% on the first $7,000 of each employee’s annual wages. Employers who pay their state unemployment taxes in full and on time receive a credit of up to 5.4%, dropping the effective federal rate to 0.6%.⁶ Employers in states with outstanding federal unemployment loans may face a reduced credit, meaning the effective rate climbs above 0.6%. The U.S. Department of Labor publishes a list of affected states each fall.

H-2A Visa Workers

Foreign agricultural workers admitted on H-2A temporary visas get special treatment that simplifies the picture considerably. Their wages are exempt from Social Security and Medicare taxes regardless of amount, so you shouldn’t report H-2A wages in the Social Security or Medicare wage boxes on Form W-2 or on the corresponding lines of Form 943.⁸ H-2A wages are also exempt from FUTA.⁹

Federal income tax withholding isn’t mandatory either, though you and the worker can agree to voluntary withholding by W-4. Watch one trap: if an H-2A worker doesn’t provide a Social Security number or ITIN and your aggregate annual payments to that worker reach $600 or more, backup withholding at 24% kicks in automatically.⁸

Family Members Working on the Farm

Federal law carves out meaningful exemptions for family labor. A child under 18 working for a parent’s sole proprietorship, or for a partnership where both partners are the child’s parents, is exempt from FICA taxes entirely.³ For FUTA, the exemption reaches children under 21.⁷ Services performed by one spouse for the other are also exempt from FUTA.

These exemptions don’t apply when the farm operates as a corporation, or as a partnership that includes non-parent partners. In those structures the legal employer is the entity, not the parent, so the standard thresholds apply to family members the same as any other worker. Farms that incorporate for liability protection often miss this consequence.

Crew Leader Rules

When a third party assembles and manages a crew, who owes the employment taxes depends on the legal relationship between the crew leader and you. A crew leader is treated as the employer of the workers they furnish if the crew leader pays the workers and there’s no written agreement designating the crew leader as your employee.¹⁰ Under those conditions the workers are the crew leader’s employees for FICA purposes, and the crew leader tracks the $150 test, withholds, and files.

If the crew leader doesn’t actually pay the workers, or if a written agreement designates the crew leader as your employee, you’re the employer of record and you take on the tax obligations. Document the arrangement in writing. Without clear paperwork, the IRS will typically look at who actually handed the workers their pay.

Forms, Deadlines, and Deposit Schedules

Agricultural employers report FICA taxes and income tax withholding on Form 943, not the Form 941 used by most businesses. For the 2025 tax year, Form 943 is due February 2, 2026. If you deposited all taxes on time throughout the year, you get an extra eight days, extending the deadline to February 10, 2026.¹¹ FUTA is reported annually on Form 940, also due February 2, 2026, with the same February 10 extension for on-time depositors.¹²

How often you deposit during the year depends on your liability in a prior lookback period. Form 943 liability of $50,000 or less during the lookback puts you on a monthly deposit schedule; more than $50,000 puts you on a semi-weekly schedule.¹³ A next-day rule sits on top: if you accumulate $100,000 or more in employment taxes on any single day, the entire amount must be deposited by the close of the next business day. Form 943 deposits and any Form 941 deposits for non-agricultural employees are tracked separately and never combined for these calculations.

Penalties for Late Deposits and Non-Payment

Late deposit penalties run on a sliding scale based on how many days late the deposit arrives:

1 to 5 days late: 2% of the unpaid amount.
6 to 15 days late: 5% of the unpaid amount.
More than 15 days late: 10% of the unpaid amount.
More than 10 days after the first IRS demand notice: 15% of the unpaid amount.

The tiers don’t stack. The IRS applies whichever single rate matches how late the deposit is.¹⁴

The bigger risk is the trust fund recovery penalty. Employment taxes withheld from workers’ pay are held in trust for the government. Any person responsible for collecting and paying those taxes who willfully fails to do so faces a personal penalty equal to 100% of the unpaid trust fund amount.¹⁵ “Responsible person” is read broadly and can include farm owners, bookkeepers, and anyone with authority to decide which bills get paid. This penalty is assessed against individuals personally, not just the business.
