A small farm that keeps animals for profit can deduct the ordinary, necessary costs of running it: feed, hay, veterinary care, breeding fees, fencing and equipment repairs, fuel, utilities on the farm, pasture rent, farm insurance, loan interest, hired labor, and the gradual write down (depreciation) of things like barns and purchased breeding stock. Those deductions go on Schedule F, the farm profit or loss form most animal operations file. The honest catch, and the reason this page exists, is a single word in that list: profit. The IRS only lets you take the full sweep of farm deductions if your operation is a business run to make money, not a hobby. Get on the wrong side of that line and your deductions shrink dramatically while your income stays fully taxable. The profit motive and the deductions themselves rest on the same evidence: books complete enough to show the operation is run to make money and to back every number you claim. This is general education, not tax advice, so treat the specifics as a map and confirm anything that touches your own return with a CPA or enrolled agent who works with farms.
The first question the IRS asks: business or hobby?
Before any of the deductions below matter, your operation has to clear one threshold: is it a business or a hobby? The distinction is not about whether you love the animals. It is about profit motive, and the tax code treats the two very differently.
The governing rule is Internal Revenue Code section 183, usually called the hobby-loss rule. It comes with a safe harbor most farmers have heard some garbled version of. If your activity shows gross income greater than its deductions in at least 3 of any 5 consecutive tax years, the IRS presumes you are in it for profit (26 U.S. Code section 183). For an activity that consists mainly of breeding, training, showing, or racing horses, the window stretches to 2 profitable years out of 7, because Congress recognized that a horse operation can take much longer to turn the corner.
Missing the presumption does not automatically make you a hobby. It just means the burden shifts to you to show a genuine profit motive, and the IRS weighs that using the nine factors in Treasury Regulation section 1.183-2(b). Among them: whether you run the activity in a businesslike way and keep real books, your own or your advisers’ expertise, the time and effort you put in, whether the assets might appreciate, your track record in similar ventures, your history of income and losses, the size of any occasional profits, whether you have other income the losses conveniently offset, and how much personal pleasure or recreation is involved. No single factor decides it. An auditor looks at the whole picture, and the regulation specifically notes that carrying the activity on in a businesslike manner, with complete and accurate records, points toward a profit motive.
Why does this matter so much for the deductions on this page? Because if your operation is ruled a hobby, the arithmetic gets ugly. You still have to report every dollar of income the animals bring in, but your ability to write off the expenses against it is sharply limited. For tax years 2018 through 2025 the Tax Cuts and Jobs Act suspended the miscellaneous itemized deductions that hobby expenses used to fall under, so a hobby could not deduct those expenses at all, and later legislation made that elimination permanent rather than letting it lapse. The current-year specifics are still worth confirming with a tax professional for your own return. The practical takeaway does not move: a genuine farm business deducts its costs, a hobby is taxed on its income with little relief for the costs. That gap is the whole reason to run and document the operation like the business it is.
What an animal operation can actually deduct
Once you are operating as a business, the deductible universe is broad. IRS Publication 225, the Farmer’s Tax Guide, frames it simply: you can deduct the ordinary and necessary costs of running a farm for profit. Ordinary means common and accepted in farming, necessary means helpful and appropriate for your operation. For a place that keeps animals, that covers a lot of the checkbook:
- Feed, hay, and supplements. Purchased feed, grain, concentrates, forage, and mineral programs. For most livestock operations this is the single largest expense line.
- Veterinary, breeding, and medicine. Vet visits, vaccines, medications, semen, and breeding and stud fees.
- Supplies and small tools. Ear tags, syringes, halters, buckets, and the steady drip of consumables a barn goes through.
- Repairs and maintenance. Fixing fence, gates, waterers, and equipment, as opposed to building something new, which usually has to be capitalized instead.
- Fuel, oil, and farm utilities. Diesel and gas for the truck and tractor in farm use, plus the power and water that run the barn.
- Rent or lease, insurance, interest, and taxes. Pasture or ground rent, farm (not personal health) insurance, interest on an operating or livestock loan, and property tax on farm assets.
- Hired labor. Wages you pay workers, which is separate from your own draw as the owner.
Two boundaries trip people up. First, the land itself is never deductible or depreciable. You recover the cost of bare land only when you sell it, though improvements you make to it, fencing, drainage, certain structures, are handled separately. Second, farm expenses are strictly business. A truck used part for the farm and part for the family gets split by business use, and anything purely personal stays off Schedule F entirely.
If you want the line-by-line version, where each of these maps onto a specific Schedule F box, that lives in the companion livestock bookkeeping guide, which walks through building your categories to match the form.
Depreciation: the big-ticket deductions
Some purchases are too large, and too long lived, to write off in the year you buy them. Instead you recover the cost gradually through depreciation, and for an animal operation the most important and most misunderstood version of this involves the livestock themselves.
Here is the rule worth getting right. Purchased breeding, dairy, draft, and sporting livestock are depreciable business property. You capitalize what you paid and write it off over a recovery period (purchased breeding cattle generally fall in a 5 year period under MACRS). Animals you hold primarily to sell to customers, feeders and market stock, are inventory, not depreciable property, and never enter this treatment. And a raised animal is different again: if you already deducted the feed and vet and other costs of raising it as you went, it carries no remaining cost basis to depreciate, because you have effectively written it off along the way. So the breeding cow you bought and keep for years is a depreciable asset; the steer you are finishing for sale is inventory; the heifer you raised yourself usually has nothing left to depreciate.
On qualifying purchases, two accelerators can turn a multi year write down into a large first year deduction. Section 179 expensing lets you deduct the full cost of qualifying property in the year you place it in service, up to a cap that for 2026 is 2,560,000 dollars, phasing out once total qualifying purchases exceed 4,090,000 dollars (figures adjusted upward under the 2025 tax law and for inflation). Tangible personal property qualifies, and the IRS treats livestock such as cattle, hogs, sheep, goats, and horses as qualifying property, along with single purpose agricultural structures built to house or feed a particular kind of livestock. Bonus depreciation is the second lever: the 2025 One Big Beautiful Bill Act restored 100 percent first year bonus depreciation, permanently, for qualifying property acquired after January 19, 2025, and the IRS issued interim guidance on the change in Notice 2026-11 in January 2026. The phrase that does all the work in both provisions is “placed in service.” You get the deduction in the year the asset is actually put to its farm use, and only for property that qualifies. Resale inventory is excluded from both.
The dollar figures, elections, and which lever to pull in a given year are genuinely a talk-to-your-CPA topic. Section 179 is capped at your business income, so electing a big deduction in a low income year can push part of it past what you can use that year. The disallowed amount is not lost: it generally carries forward to a later year, so the usual consequence is that the write-off is deferred rather than taken all at once. Bonus depreciation, meanwhile, interacts with your whole return. What matters here is narrower: purchased breeding, dairy, and draft animals and farm buildings are depreciable, resale stock is not, and the accelerators exist.
When you sell breeding stock, the rules flip
The deductions above are the input side. When you eventually sell a depreciable breeding, dairy, or draft animal, do not expect it to show up on Schedule F like a load of feeder calves. It does not. That animal is business property, and its sale is reported on Form 4797 under Internal Revenue Code section 1231, not on your farm profit or loss form (Iowa State’s Center for Agricultural Law and Taxation lays this out clearly for raised breeding stock).
Section 1231 is a favorable hybrid. A net gain on qualifying section 1231 property can be treated as long term capital gain, taxed at the lower capital gains rates, while a net loss is treated as an ordinary loss. There are two wrinkles worth knowing. Depreciation recapture comes first: gain up to the depreciation you already claimed is taxed as ordinary income, and only the remainder gets 1231 treatment. And there is a holding period. Cattle and horses held for draft, breeding, dairy, or sporting purposes must be held at least 24 months to qualify; other livestock must be held at least 12 months. One more practical note that surprises new owners: because these sales are reported on Form 4797 rather than Schedule F, the gain generally escapes self-employment tax.
This is precisely why it pays to record each breeding animal’s purchase date, purchase price, and purpose the day you acquire it. Answering the 1231 and holding period questions years later without good records is guesswork, and guesswork is what audits punish.
Records are what make a deduction hold up
A deduction you cannot document is a deduction you can lose. The IRS puts the burden of proof on the taxpayer, so the receipts, invoices, canceled checks, breeding records, and veterinary bills behind each number are not busywork. They are the deduction. Publication 225 is blunt on this point: you need records to support the income and the expenses you report.
Good records do double duty on the hobby question too. Recall that the first factor in the section 1.183-2(b) test is whether you carry on the activity in a businesslike manner and keep complete and accurate books. Clean records are simultaneously your audit defense on the deductions and part of your evidence that this is a business, not a pastime. That is a rare case where the tax-motivated habit and the good-management habit are the same habit.
The mechanics can live anywhere sane, a notebook, a spreadsheet, or software, as long as the categories are consistent and the entries are timely. If you would rather keep the animal records and the money records together, that is the shape of the Creatures finance tools. The help article on setting up your books walks through creating income and expense categories, recording money in and out covers logging costs and sales as they happen, and an animal’s finances and ROI explains attaching costs to a single animal, which is exactly what makes a breeding animal’s basis and holding period answerable later.
A quick word on self-employment tax
Deductions reduce your farm’s net profit, and that net profit does more than face income tax: it also flows to self-employment tax, which funds your Social Security and Medicare because no employer is withholding them for you. Be careful with the shorthand here, though, because “15.3 percent of your profit” is not how the math works. Your Schedule F profit and your Schedule SE net earnings are different figures. The SE calculation generally starts from 92.35 percent of net earnings, the Social Security portion is capped at an annual wage base, an additional Medicare amount can apply at higher incomes, and farmers have optional methods that change the computation again. You file Schedule SE once net earnings reach 400 dollars, and you get to deduct half of the self-employment tax when figuring adjusted gross income. The companion livestock bookkeeping guide covers this in more detail; it matters here because every legitimate deduction you take lowers the base this tax is figured on.
Where a tax professional has to take over
This guide is deliberately educational, and small farm taxation has real edges where general information runs out. Bring in a CPA or enrolled agent for anything that changes your legal or tax position: settling the business-versus-hobby question if your losses are stacking up, choosing a structure (sole proprietor, partnership, LLC, or corporation), making section 179 and depreciation elections, timing large deductions across a good year and a lean one, handling the sale of breeding stock and its section 1231 and recapture treatment, and special provisions like income averaging for farmers or deferral of weather related livestock sales. An hour with someone who does farm returns for a living almost always costs less than getting one of those decisions wrong, and your clean, well categorized records are what make that hour productive.
Frequently asked questions
Can a small farm deduct feed and vet bills?
Yes, if the farm is run as a business for profit. Feed, hay, supplements, veterinary care, and breeding fees are ordinary and necessary farm expenses deductible on Schedule F, per IRS Publication 225. If the operation is treated as a hobby rather than a business, the deduction for those costs is sharply limited while the income stays taxable, which is why the profit-motive question matters. Confirm your situation with a tax professional.
What is the hobby-loss rule for farms?
Under IRC section 183, the IRS presumes an activity is run for profit if it shows a profit in at least 3 of 5 consecutive years, or 2 of 7 years for horse breeding, training, showing, or racing. Missing that presumption does not end the matter; the IRS then weighs nine factors, including how businesslike your records and operation are, to judge profit motive.
Is a breeding cow an expense or a depreciable asset?
A purchased breeding, dairy, or draft animal is depreciable business property that you write off over time, not a one-time expense. An animal held to sell is inventory and is not depreciated, and a raised animal usually has no remaining basis to depreciate because you already deducted the cost of raising it. When you sell a depreciable breeding animal, it is reported on Form 4797 as section 1231 property, not on Schedule F.
Can I write off livestock the year I buy them?
Sometimes. Qualifying purchased breeding, dairy, draft, or sporting livestock placed in service can be eligible for section 179 expensing or 100 percent bonus depreciation, which accelerate the deduction into year one. Animals bought for resale are inventory and do not qualify. The elections interact with the rest of your return, so run them past a CPA.
Is the cost of my farmland deductible?
No. Bare land is neither deductible nor depreciable; you recover its cost only when you sell it. Improvements, buildings, and equipment are handled separately and may be depreciated or expensed.
