What Is Schedule F on a Tax Return: Farm Profit and SE Tax

Schedule F is the IRS form that farmers file with their Form 1040 to report income and expenses from raising crops, livestock, or other farm products for sale. The Schedule F tax form calculates whether your farm ended the year with a profit or a loss, and the result flows onto your personal return, where it affects both income tax and self-employment tax. Farmers who use it also gain access to several tax rules that other businesses don’t get, including income averaging, a two-year loss carryback, and relaxed estimated tax deadlines.

Who Files Schedule F

You file Schedule F if you cultivate, operate, or manage a farm for profit, whether you own the land or rent it. The IRS defines “farm” broadly: livestock, dairy, poultry, fish, fruit, and vegetable operations, along with ranches, plantations, orchards, and groves.¹ A tenant growing corn on rented acreage and a fish farmer selling tilapia both belong here.

Some farm-adjacent activities go on other forms. Agricultural services like soil preparation or veterinary work, breeding pets such as dogs and cats, and managing someone else’s farm for a fee all belong on Schedule C, not Schedule F.² A landlord who leases farmland for a share of the crop but doesn’t materially participate in the operation reports that rent on Form 4835 instead; only crop-share landlords who actively help manage or work the farm use Schedule F.¹

Is Your Farm a Business or a Hobby?

The IRS treats farming as a business only if you’re running it to make money. Under Section 183 of the Internal Revenue Code, a farm that shows a profit in at least three out of five consecutive tax years is presumed to be for-profit.³ Horse breeding and racing get a longer runway: two profitable years out of seven. Missing the threshold doesn’t automatically disqualify you, but it puts the burden on you to prove profit motive. If the IRS reclassifies your farm as a hobby, you lose the ability to deduct farm losses against your other income.

Income That Belongs on Schedule F

Schedule F captures more than just what you get for the corn or cattle. Common income categories include:

Sales of livestock, produce, grains, and other items you raised on the farm.
Cooperative distributions reported on Form 1099-PATR, including both cash patronage dividends and retained allocations.
Agricultural program payments, Conservation Reserve Program payments, and disaster relief reported on Form 1099-G.
Custom hire income for using your equipment on another farmer’s land.
Bartering: the fair market value of goods or services you received in place of cash.

Crop Insurance and Disaster Payments

Crop insurance and federal disaster payments that replace lost harvests are farm income in the year received. You can elect to defer them one year if you can show you would normally have sold the damaged crop in the following tax year.⁴ The deferral can keep a big insurance check from spiking your income into higher brackets.

Breeding Livestock Doesn’t Go Here

One common filing error: reporting sales of breeding, dairy, draft, or sporting livestock on Schedule F. Those sales go on Form 4797 because the animals qualify as business property eligible for capital gain treatment. Cattle and horses must have been held at least 24 months; other livestock such as hogs and sheep need 12 months.⁵ Animals sold before meeting those periods produce ordinary income. Putting the sale on the wrong form can cost you the lower capital gains rate.

Farm Expenses You Can Deduct

Schedule F lists more than 20 expense categories, and subtracting them from gross farm income produces your net profit or loss. The main ones:

Feed, seed, fertilizer, lime, and chemicals such as pesticides and herbicides.
Veterinary bills, medicine, and breeding fees.
Wages paid to hired farmworkers.
Repairs and maintenance on equipment, fences, and buildings.
Interest on farm mortgages (reported on Form 1098) and on operating loans.
Insurance premiums for fire, storm, crop, and liability coverage.
Rent or lease payments for land, equipment, or vehicles used in farming.

Depreciation and Section 179

Buy a combine or build a grain bin and you normally recover the cost through annual depreciation deductions over the asset’s useful life.⁶ Section 179 lets you write off the full purchase price in the year you put the property into service, up to $2,560,000 for tax year 2026. The deduction phases out once your total qualifying purchases exceed $4,090,000 for the year. The immediate write-off is especially useful when you’ve had a strong income year and want to offset it with a big equipment purchase.

The 50% Rule on Prepaid Supplies

Cash-method farmers often prepay for next year’s feed, seed, or fertilizer to secure a deduction now. The tax code allows this, but if your prepaid supplies exceed 50% of your other deductible farm expenses for the year, the excess gets pushed into the year you actually use them.⁷ Exceptions apply if prepaid supplies stayed below 50% of other farm expenses for the prior three years, or if the prepayment was driven by unusual circumstances like a sudden price spike.

Soil and Water Conservation Costs

Farmers can deduct soil and water conservation work rather than capitalizing it. This covers terracing, grading, drainage ditches, earthen dams, and windbreaks. The annual deduction is capped at 25% of gross farm income, with any excess carried forward.⁸ The work must follow a plan approved by the USDA’s Natural Resources Conservation Service or a comparable state agency. Draining wetlands and preparing land for center-pivot irrigation don’t qualify.

Cash, Accrual, or Crop Method

Most farmers use the cash method: income counts when the money comes in, and expenses count when you pay them.¹ It’s easier to track and gives you some control over timing, since you can delay a grain sale into January or prepay expenses in December to shift income between years.

The accrual method records income when earned and expenses when incurred, regardless of when cash moves. Larger operations sometimes prefer it because it matches revenue against costs more precisely.

A third option, the crop method, is designed for crops planted in one year and harvested in the next. With IRS approval, you can deduct all production costs in the same year you report the sale, keeping a full crop cycle on one return.¹ The IRS requires consistency once you pick a method; switching later requires filing for permission.

How the Profit or Loss Reaches Your Return

Total farm income minus total farm expenses equals your net farm profit or loss.² That figure moves to Schedule 1 of Form 1040 and from there into your overall tax calculation. Farm profit is taxed at ordinary federal rates, running from 10% to 37% for 2026.⁹

A farm loss can offset other income on your return, such as a spouse’s wages. The excess business loss limitation caps how much can offset non-business income in one year: $256,000 for single filers and $512,000 for joint filers in 2026. Anything disallowed becomes a net operating loss carryforward.

The Two-Year Loss Carryback

Farmers kept a benefit that most businesses lost after 2017. A farm net operating loss can be carried back two years to offset income you already paid tax on, generating a refund.¹⁰ Anything not absorbed carries forward indefinitely, though a carryforward can offset only up to 80% of taxable income in each future year. You can elect to skip the carryback and carry the full loss forward if that math works out better.

Self-Employment Tax on Farm Profit

A net farm profit of $400 or more triggers self-employment tax, calculated on Schedule SE.¹¹ The rate is 15.3%: 12.4% for Social Security and 2.9% for Medicare.¹² The Social Security portion applies only up to $184,500 of net earnings in 2026; Medicare has no cap.¹³ Half of the self-employment tax is deductible as an adjustment to income on your 1040.

Income Averaging With Schedule J

Farm income swings hard from year to year: a drought wipes out revenue, then the next year’s bumper crop pushes you into a much higher bracket. Schedule J lets you average all or part of the current year’s farm income over the prior three years, effectively taxing part of this year’s income at the lower rates you would have paid earlier.¹⁴

Sole proprietors, partners, and S corporation shareholders can elect it. C corporations, estates, and trusts cannot.¹⁵ Averaged income can include gains from selling farm equipment or other property regularly used in the operation, if sold within a reasonable time. Gains from selling land or development rights are excluded.

Estimated Tax Deadlines for Farmers

Most self-employed taxpayers pay quarterly estimated taxes. Farmers get different rules if at least two-thirds of their gross income comes from farming.¹⁶ Two options open up: skip the first three quarterly deadlines and make a single estimated payment by January 15 of the following year, or skip estimated payments entirely by filing your return and paying the full balance by March 1. Most farmers use the March 1 option because it removes the guesswork of estimating tax on income that depends on harvest results and commodity prices you won’t know until year-end.

Miss those deadlines and the penalty is figured on Form 2210-F, not the standard Form 2210. You owe no penalty if your total tax minus withholding is under $1,000, or if you had no tax liability the prior year.¹⁷

If You Hire Farm Workers

Wages you pay to farmworkers stay off Schedule F’s income section, but they show up as a labor expense and trigger separate employer filings. Agricultural employers use Form 943 instead of the Form 941 that most other employers file. You owe Social Security and Medicare tax on farmworker wages once you pay any single worker $150 or more in cash wages during the year, or pay all farmworkers a combined $2,500 or more.¹⁸ Meeting either test is enough. Federal unemployment tax has its own agricultural thresholds tied to quarterly wages and worker counts.¹⁹
