Short answer: Racing is a business or a hobby to the IRS based on profit motive. Run it like a real business — chasing money, keeping books to prove it — and your costs may be deductible. Race mainly for fun and it’s a hobby: the income is still taxable, the expenses generally are not.
Key takeaways
U.S. tax note: General education, not tax or legal advice. Forming an entity, keeping receipts or running a tracking app does not by itself establish trade-or-business status or make an expense deductible. Federal, state and local rules differ and change mid-year — the 2026 mileage rate did exactly that. Verify the figures for the tax year you are actually filing with a qualified tax professional.
That one distinction — business or hobby — decides whether the money you pour into racing does anything for you at tax time. It’s the question underneath every “can I write off my race car” argument in the pits. And the honest answer is: it depends on how you run the program, not on how fast you go.
Let’s walk it in plain English: what the IRS looks at, why documentation is the whole ballgame, and how to know which side of the line you’re on. One loud caveat up front: this is general education, not tax advice. Everybody’s situation is different — take yours to a qualified tax professional.
Here’s the part a lot of racers miss. The stakes are lopsided.
If your racing is a business, you report income and you can generally deduct ordinary and necessary expenses against it — entry fees, tires, fuel, parts, travel — on a Schedule C. Losses can offset other income, within limits.
If your racing is a hobby, the math is brutal. Any prize money, contingency, or sponsorship you take in is still taxable income you have to report. But the expenses? Under the Tax Cuts and Jobs Act, hobby expenses became nondeductible starting with the 2018 tax year, and the One Big Beautiful Bill Act made the suspension of 2% miscellaneous itemized deductions permanent going forward. IRS Publication 529 puts it flatly: hobby expenses “are miscellaneous itemized deductions and can no longer be deducted,” while “you must still report the income you receive on your Schedule 1 (Form 1040).”
Read that twice. Hobby income is taxed. Hobby expenses are not deductible. So if the IRS reclassifies your “racing business” as a hobby, you can end up paying tax on your winnings with nothing to write off against them. That’s why this question is worth getting right — and worth documenting before anyone asks. (Current as of the 2026 tax year; always confirm the latest on irs.gov.)
What the IRS is deciding is whether you’re in it to make money. It doesn’t care whether you love racing — plenty of real businesses are run by people who love the work.
Its own guidance is blunt: “businesses operate to make a profit while hobbies are for pleasure or recreation” (IRS). And there’s no magic switch — “No single thing is the deciding factor,” per the same IRS guidance. Instead, the agency weighs the whole picture under Section 183 of the tax code, the “hobby loss” rule.
Two tools do the heavy lifting: a profit presumption, and a nine-factor test. Know both.
Start with the simplest bar: if your activity shows a profit — gross income exceeding your deductions — in at least three of the last five consecutive tax years, the IRS generally presumes you’re in it for profit (26 U.S.C. §183(d); The Tax Adviser). (One oddball exception in the statute: activities that are mainly breeding, training, showing, or racing horses get a friendlier two-of-seven-year test. Cars don’t.)
Clear that bar and the burden effectively flips: the IRS has to argue you’re a hobby, not the other way around. Miss it — as a lot of grassroots racers do, because racing is expensive and profits are thin — and you’re not automatically a hobby. You just don’t get the presumption. You have to win the argument on the nine factors below.
That’s the key mindset: not turning a profit doesn’t make you a hobby. Startups lose money. Real businesses have bad years. But the more red ink you show, the more the factors — and your records — have to carry the load.
Treasury Regulation §1.183-2(b) lists nine factors the IRS weighs — the regulation’s own words: “No one factor is determinative in making this determination.” This is the heart of it — here they are, numbered, in plain racer terms. Score yourself honestly on each.
Do you run it in a businesslike way? Separate bank account, real books, receipts, a written plan you actually adjust. This is the factor you have the most control over — and the one that shows up first in every case.
Do you (or your advisors) have expertise? Do you know the craft and the money side — how the class pays, what a competitive budget looks like, where the revenue comes from? Consulting people who’ve made racing pay counts too.
How much time and effort do you put in? Substantial, sustained time points toward profit intent. Full weekends in the shop and at the track help; a couple of casual outings a year don’t.
Could your assets appreciate? A car, hauler, engine, or equipment that could gain value — or be sold for more than you paid — can support a profit motive even in a losing year.
Have you made money at other ventures before? A track record of turning businesses profitable — similar or dissimilar — weighs in your favor.
What’s your history of income and losses? Occasional startup losses are normal. A long unbroken string of losses with no plan to fix it is the single biggest hobby flag.
When you do profit, how much? A rare, tiny profit against giant losses looks like an accident. Meaningful profit — even occasionally — looks like a business finding its footing.
What’s your financial situation? If racing is your only income source, that points to profit motive. If you have plenty of other income and the losses conveniently shelter it, the IRS leans hobby.
How much personal pleasure or recreation is involved? Racing is fun — that’s not disqualifying. But if enjoyment looks like the main point and profit is an afterthought, that cuts against you.
No factor is worth more than another on paper, but in practice Factor 1 — businesslike records — is where cases are won and lost. More on that next.
The pattern is simple: decisions and records that show you’re trying to make money. You can’t fake profit motive after the fact. You build the evidence as you go. A racer the IRS would treat as a business generally has:
| Businesslike (business signal) | Casual (hobby signal) |
|---|---|
| Separate bank account and card for racing | Everything mixed with personal spending |
| Books that track income and every expense | Receipts in a shoebox, or nowhere |
| A written plan with a path to profit | “I just want to race” |
| Real effort to earn — sponsors, contingency, purses, resale | No revenue strategy at all |
| Documented expertise; advice from people who’ve done it | Winging it on gut alone |
| Adjusting the operation to cut losses | Same money-losing routine, year after year |
Chase sponsors. Learn which purses and contingency programs actually pay in your class. Keep clean books. When a season loses money, change something and write down why. That’s not paperwork for its own sake — it’s the exact behavior the nine factors reward.
If you’re nodding at these, tighten up before tax season:
None of these alone sinks you. Stacked together, they paint the picture the IRS is looking for.
Is your racing a business or a hobby? It’s a business if you can show — with records, effort, and intent — that you’re genuinely trying to make money. It’s a hobby if you’re mainly racing for the love of it, in which case the winnings are taxable and the costs generally aren’t deductible.
The line isn’t your lap times or your win count. It’s your documentation and your intent. If you’re ever questioned, the racer with a separate account, clean books, a written plan, and a real effort to earn is in a completely different position than the one with a shoebox of receipts and a great story.
Build that record before you need it. And because everyone’s tax situation is different — and the rules change — run the specifics past a qualified tax professional or CPA before you file. This post is general education, not tax advice.
Yes. Hobby income is taxable. The IRS is clear that money from an activity you don’t run for profit — prize money, contingency, sponsorship — still gets reported, generally on Schedule 1 of Form 1040. The hobby label changes whether you can deduct expenses, not whether the income counts (IRS Pub 529).
Generally no. Since the 2018 tax year, hobby expenses have been nondeductible miscellaneous itemized deductions, and that suspension is now permanent. So a hobby racer can owe tax on winnings with no offsetting deductions. Only a racing business can deduct ordinary and necessary expenses. Confirm current rules with a tax pro.
There’s no hard cutoff. The 3-of-5-year rule is a presumption of profit if you’re profitable in three of five years — not a limit on losses. You can lose money and still be a business if the nine factors and your records show real profit intent (The Tax Adviser).
Keep businesslike records. Separate bank account, complete books, receipts, and a written plan you actually adjust. It’s the first of the nine factors and the one you fully control. Good documentation is what wins if your profit motive is ever questioned.
Not by itself, but it helps. Consulting qualified advisors is part of the “expertise” factor and signals you’re running things seriously. More importantly, a CPA who knows your situation can tell you which side of the line you’re really on — which is exactly why you should talk to one.
You can absolutely handle all of this by hand — a separate checkbook, a shoebox of receipts, a spreadsheet you swear you’ll update. Plenty of racers do. But the whole point of the nine factors is that businesslike recordkeeping is what protects you, and that’s exactly the part that’s easy to let slide when you’re wrenching until midnight.
RaceTrips is built to be that businesslike record — the kind the IRS factors reward:
It won’t decide your case for you, and it isn’t tax advice — but it makes you look, and operate, like the business you’re claiming to be.
