Schedule F (Form 1040) is the IRS form you use to report the income and expenses of a farming business you run as a sole proprietor or through a single-member LLC. The net profit or loss from Schedule F carries to your Form 1040 and gets taxed as ordinary income, and it also feeds Schedule SE for self-employment tax. Farming has its own tax rules on accounting method, income timing, loss carrybacks, and income averaging, so the form does more work than a straight income-and-expense tally suggests.
Who Files Schedule F
You file Schedule F if you operate a farm for profit as a sole proprietor or through a single-member LLC that hasn’t elected corporate treatment.1Internal Revenue Service. Instructions for Schedule F (Form 1040) The IRS reads “farming” broadly: cultivating land, raising livestock, running nurseries or orchards, and managing ranches or poultry operations all count.2Internal Revenue Service. Publication 225 – Farmer’s Tax Guide If you’re taking on the risks of production and managing the operation with the goal of making money, you’re a farmer for tax purposes.
Two boundaries matter. Partnerships report farm income on Form 1065 and S corporations on Form 1120-S, not on Schedule F. And if you own farmland, lease it out for a share of the crops, and don’t materially participate in running the operation, you file Form 4835 instead. Form 4835 reports farm rental income separately and doesn’t trigger self-employment tax.3Internal Revenue Service. About Form 4835, Farm Rental Income and Expenses The line runs through whether you’re actively managing the farm or simply collecting rent.
Sales of farm assets, like land, breeding livestock held over 24 months, or depreciated machinery, don’t go on Schedule F either. Those move to Form 4797, where prior depreciation on equipment gets recaptured as ordinary income before any capital gains treatment applies.
Pick Your Accounting Method First
Before you fill in any income or expense line, you need an accounting method, and the choice matters. Most small farming operations use the cash method: you report income when payment lands and deduct expenses when you pay them. That timing flexibility lets you shift taxable income between years by pulling purchases forward or delaying a sale past December 31.
The accrual method counts income when earned and expenses when incurred, regardless of when cash actually moves, and it requires tracking beginning and ending inventories of livestock, crops, and supplies each year. Whichever method you use on your first farm return, you’re generally stuck with it. Switching later requires filing Form 3115 and getting IRS consent, which is automatic for some routine changes and discretionary for others.4Internal Revenue Service. Instructions for Form 3115 – Application for Change in Accounting Method
Reporting Farm Income in Part I
Part I captures gross farming income. The main lines include sales of livestock and produce you raised, sales of purchased livestock or resale items (reduced by your cost basis), cooperative distributions on Form 1099-PATR, agricultural program payments, Commodity Credit Corporation loan proceeds, crop insurance payouts, and custom hire income from doing machine work for other farmers.5Internal Revenue Service. 2025 Schedule F (Form 1040)
Two lines carry elections worth knowing. CCC loan proceeds can be reported as income in the year received rather than waiting until you sell the commodity; once you make the election, it applies to all future CCC loans unless the IRS approves a change. Crop insurance proceeds can be deferred to the following year if you can show you would have normally sold the damaged crop in that later year. That deferral is useful when a disaster year would otherwise stack an insurance check on top of your normal sales.
Deducting Farm Expenses in Part II
Part II is where most of the tax savings show up. Schedule F lists more than 20 expense categories, and nearly every operating cost fits somewhere. The categories most farmers use:
- Feed, seed, fertilizer, and chemicals
- Labor (wages paid to farmworkers, reduced by any employment credits claimed)
- Repairs and maintenance on equipment, buildings, and fences
- Rent or lease payments, split between vehicles or equipment and land or animals
- Interest, with mortgage interest reported separately from other loan interest
- Insurance on farm property and liability (health insurance goes elsewhere on the 1040)
- Veterinary, breeding, and medicine costs
- Gasoline, fuel, and oil for farm equipment and vehicles
- Conservation expenses for soil and water conservation on farmland
- Utilities, storage, freight, and general supplies
Car and truck expenses have their own line and require attaching Form 4562 if you’re also claiming depreciation. Pension and profit-sharing contributions for employees are deductible here too.5Internal Revenue Service. 2025 Schedule F (Form 1040) Every expense needs documentation — receipts, bank statements, or canceled checks — and you should keep those records for at least three years after filing.6Internal Revenue Service. How Long Should I Keep Records
Separate from Schedule F, you can claim a credit on Form 4136 for federal excise taxes paid on fuel used off-highway for farming. A credit reduces your tax dollar-for-dollar, which is generally more valuable than a deduction of the same size.7Internal Revenue Service. About Form 4136, Credit For Federal Tax Paid On Fuels
Depreciation and Section 179
Farm equipment, buildings, and other long-lived assets can’t be expensed all at once. You recover their cost over time through depreciation, using the Modified Accelerated Cost Recovery System (MACRS) for property placed in service after 1986.8Internal Revenue Service. Topic No. 704, Depreciation Tractors, combines, grain bins, fencing, and farm buildings each have their own MACRS recovery period.
Section 179 lets you expense the full cost of qualifying equipment in the year you buy it. For 2025 the maximum deduction was $1,320,000, phasing out once total equipment purchases exceeded $3,310,000.9Internal Revenue Service. Instructions for Form 4562 These limits adjust for inflation each year, so check the current Form 4562 instructions before relying on the number. Section 179 also can’t exceed your taxable income from active trades or businesses, so it won’t create or deepen a loss.
Bonus depreciation is a separate accelerated write-off that’s been phasing down since 2023. It drops to 20% of eligible property cost for 2026, from 40% in 2025. As bonus depreciation shrinks, Section 179 does more of the work for farmers looking to front-load deductions on major purchases.
The Hobby Loss Rule
The IRS won’t accept farm losses year after year without evidence you’re actually farming for profit. Under Internal Revenue Code Section 183, if your farm shows a net profit in at least three of the last five tax years, the IRS generally presumes you’re in business.10Office of the Law Revision Counsel. 26 U.S. Code 183 – Activities Not Engaged in for Profit For horse breeding, training, showing, or racing, the bar is lower: profit in two of the last seven years.11Internal Revenue Service. Is Your Hobby a For-Profit Endeavor
Missing the presumption doesn’t automatically make your farm a hobby. It shifts the burden to you to prove profit intent through factors like how you run the business, your expertise, and the time you put in. If the IRS does reclassify your farm as a hobby, losses can no longer offset your other income, and you may face an accuracy-related penalty of 20% on any resulting underpayment.12Office of the Law Revision Counsel. 26 U.S. Code 6662 – Imposition of Accuracy-Related Penalty on Underpayments Most disputes with the IRS over part-time farms begin here.
Self-Employment Tax on the Net Figure
Net profit from Schedule F is subject to income tax and also to self-employment tax, which funds Social Security and Medicare. If your net farm earnings exceed $400, you file Schedule SE.13Social Security Administration. If You Are Self-Employed The rate is 15.3%: 12.4% for Social Security on net earnings up to $184,500 in 2026, plus 2.9% for Medicare on all net earnings. You calculate the tax on 92.35% of your net self-employment income and deduct the employer-equivalent half on your Form 1040.
In lean years, the farm optional method on Schedule SE lets you report a minimum level of earnings for Social Security credit purposes even when your actual profit was tiny or negative. For 2026, you can use this method if gross farm income was $10,860 or less, or if net farm profits were under $7,240.13Social Security Administration. If You Are Self-Employed Unlike the nonfarm optional method, there’s no lifetime cap on how often a farmer can use it. You pay a small amount of self-employment tax now to build Social Security credits for retirement.
Farm Income Averaging with Schedule J
Farm income swings year to year, and one strong harvest can push you into a bracket that doesn’t reflect your long-term earnings. Schedule J lets you spread your current-year farm income across the three prior tax years, which often lowers your total tax.14Office of the Law Revision Counsel. 26 USC 1301 – Averaging of Farm Income The election recalculates what your tax would have been if one-third of your “elected farm income” had been added to each of those three base years.
You choose how much of your current-year farm income to average, all of it or a portion. The benefit is greatest when the three prior years had low taxable income and the current year is unusually high. Gains from selling depreciable farm property, other than land, count as eligible farm income for averaging.15Internal Revenue Service. Instructions for Schedule J (Form 1040) The election is available only to individuals, not estates or trusts, and you make it by filing Schedule J with your return.
Losses: NOL Carrybacks and the Excess Business Loss Cap
A net operating loss from farming gets treatment most other businesses don’t have: you can carry a farming NOL back two years and apply it against income you already paid tax on, generating a refund.16Office of the Law Revision Counsel. 26 USC 172 – Net Operating Loss Deduction Most non-farm NOLs arising after 2020 can only be carried forward. You can elect to waive the carryback and carry the farming loss forward instead, but that election is irrevocable once made. Use Form 172 to claim the carryback.17Internal Revenue Service. Instructions for Form 172
There’s a ceiling on how much loss you can use in a single year. Through 2026, the excess business loss limitation caps how much business loss noncorporate taxpayers can deduct against other income, at roughly $256,000 for single filers and $512,000 for joint filers, adjusted for inflation.18Office of the Law Revision Counsel. 26 U.S. Code 461 – General Rule for Taxable Year of Deduction Anything above the cap converts to an NOL carryforward, and that carryforward can only offset up to 80% of taxable income in any future year. The provision is currently set to expire after 2026 unless Congress extends it.
Filing Deadlines and Estimated Tax
Farmers get a different timeline than most taxpayers. If at least two-thirds of your gross income comes from farming in either the current or prior tax year, you can skip quarterly estimated tax payments entirely by filing your return and paying all tax owed by March 1.19Internal Revenue Service. Topic No. 416, Farming and Fishing Income For the 2026 tax year, that means filing by March 1, 2027.20Internal Revenue Service. Farming and Fishing Income
If you’d rather file by the standard April 15 deadline, you need to make a single estimated tax payment by January 15 to avoid an underpayment penalty. Regular taxpayers make four quarterly payments; farmers meeting the two-thirds test make one. Missing the deadline you chose triggers a failure-to-file penalty of 5% of the unpaid tax for each month or partial month the return is late, up to 25%.21Internal Revenue Service. Failure to File Penalty
Individuals attach Schedule F to Form 1040 or Form 1040-SR. Nonresident aliens attach it to Form 1040-NR.1Internal Revenue Service. Instructions for Schedule F (Form 1040) The net profit or loss on Schedule F line 34 flows to Schedule 1 (Form 1040), line 6, and to Schedule SE for the self-employment tax calculation.
