Schedule C for Racers: How to Report Your Racing Income and Expenses

Last reviewed: August 3, 2026 · By the RaceYear team

Short answer: If you run your racing as a business, you report it on IRS Schedule C (Form 1040), “Profit or Loss From Business.” You list your racing income (winnings, contingency, sponsorship) at the top, subtract your racing expenses by category, and the net profit or loss carries to your Form 1040. This is general education, not tax advice — have a tax professional file.

Key takeaways

• Racers file Schedule C (Form 1040) when they operate as a sole proprietor or a single-member LLC treated as a disregarded entity.
• Part I gross receipts cover purse, contingency, and sponsorship income, and racers report it whether or not a 1099 was issued.
• Big-ticket assets like a race car, engine, or trailer are usually depreciated on Line 13 rather than deducted in one season.
• Net profit or loss lands on Line 31 and carries to Form 1040, where a profit of $400 or more generally triggers self-employment tax.
• The self-employment tax rate is 15.3% — 12.4% for Social Security plus 2.9% for Medicare — and the Social Security wage base cap changes annually.
• If the IRS treats your racing as a hobby, the income is still taxable but the expenses generally cannot offset it.

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.

Here’s the part that trips up a lot of racers the first time: Schedule C isn’t scary, it’s just a scorecard. It’s one page where you write down what your racing operation took in, what it spent, and what was left. If you’ve ever kept a season budget on a legal pad, you already understand the shape of it.

This guide walks Schedule C the way you’d walk your car in tech — line by line, in plain English — and shows which racing costs land where. One loud caveat up front, repeated all the way down: this is general information, not tax advice. The rules change, your situation is yours, and a tax professional should actually prepare and file your return. Consider this your orientation lap.

What is a Schedule C for racers, and who files it?

Schedule C (Form 1040) is titled “Profit or Loss From Business (Sole Proprietorship).” It’s the form individuals use to report income or loss from a business they run themselves. If your racing is a business and you’re not incorporated, this is very likely the form your racing lives on.

You generally file Schedule C if you’re a:

• Sole proprietor — you race as yourself, no formal entity.
• Single-member LLC treated as a disregarded entity for taxes — you formed an LLC for your race operation, but the IRS still looks through it to you.

The IRS says an activity qualifies as a business when your “primary purpose… is for income or profit” and you’re involved “with continuity and regularity.” That last part matters for racers — more on the business-vs-hobby line in a minute, because it’s the whole ballgame.

A quick note on structure: if your team is a multi-member LLC, a partnership, or an S-corp, you’re on different forms (Form 1065 or Form 1120-S), not Schedule C. Ask your tax pro which entity you actually are before you assume.

What are the five parts of Schedule C?

Schedule C has five parts. You won’t use all of them, but here’s the whole car:

Part	What it covers	Racing translation
Part I	Income	Every dollar your racing brought in
Part II	Expenses	Every dollar it cost to go racing
Part III	Cost of Goods Sold	Only if you sell inventory (most racers skip)
Part IV	Vehicle information	Miles on the tow rig, if you deduct mileage
Part V	Other expenses	The costs with no preset line

Net profit or loss comes out the bottom of Part II and carries forward. That’s the whole machine. Now let’s break down the two parts you’ll actually live in.

What racing income goes in Part I of Schedule C?

Part I starts with gross receipts on Line 1 — all the income your racing operation took in before you subtract a thing. For a grassroots racer, that usually means:

• Purse and winnings — heat money, feature payouts, points-fund checks.
• Contingency money — the manufacturer and product bonuses you claim with a decal.
• Sponsorship income — cash from a local sponsor for the panel on your quarter.
• Anything on a 1099 — if a track, series, or sponsor paid you enough, they may issue a 1099-NEC or 1099-K, and the IRS gets a copy too.

Report it all, whether or not you got a form. Missing a 1099 doesn’t make the income disappear from the IRS’s records — it just makes your return not match theirs.

Part II: mapping your racing costs to expense lines

To be deductible, an expense has to be ordinary and necessary for your racing business. This is where racers light up, because racing is expensive and Part II is where those costs become deductions. Here’s how common racing costs map to the actual Schedule C expense lines:

Schedule C line	The category	What racing costs go here
Line 8	Advertising	Team graphics, decals, hero cards, sponsor deliverables
Line 9	Car & truck expenses	Tow vehicle costs — mileage or actual, your choice
Line 13	Depreciation & Sec. 179	Big-ticket assets: race car, engine, trailer, hauler
Line 15	Insurance	Business/racing insurance (not the personal daily driver)
Line 17	Legal & professional	Your tax preparer, bookkeeping, entity fees
Line 20	Rent or lease	Shop space rent, equipment rental
Line 21	Repairs & maintenance	Parts, service, the constant fix-it spend
Line 22	Supplies	Consumables — oil, fuel additives, rags, sealer, safety wire
Line 23	Taxes & licenses	Series licenses, entry-side fees, business licenses
Line 24a	Travel	Lodging and travel to away races
Line 24b	Meals	Business meals on the road (limited — ask your pro)
Line 27b	Other expenses	Entry fees, pit passes, tires, race fuel (itemized in Part V)

A few things worth flagging. Big purchases usually get depreciated, not expensed all at once. A trailer or an engine is an asset with a multi-year life, so it typically goes on Line 13 (depreciation) rather than getting written off in one shot — though Section 179 rules can change that. This is exactly the kind of call a tax pro makes.

Tires, fuel, and entry fees don’t have their own named line. Most racers itemize them under Part V and total them onto Line 27b — the IRS moved “Other expenses (from line 48)” from 27a to 27b on the 2025 form. Keep them grouped and labeled so the number is defensible.

And the tow rig: you choose standard mileage or actual expenses for car and truck costs. Either way you need a mileage log — Part IV asks how many business miles you drove. Don’t reconstruct it from memory in April.

How does net profit or loss flow to your 1040?

Here’s the whole math, start to finish:

1. Total your income in Part I.
2. Total your expenses in Part II.
3. Income minus expenses = net profit or loss on Line 31.
4. That Line 31 number carries to your Form 1040 and, if it’s a profit, to Schedule SE for self-employment tax.

A profit adds to your taxable income. A loss can offset other income — if the IRS agrees you’re running a business and not a hobby. That “if” is doing heavy lifting, which is the next section.

Do you owe self-employment tax on racing profit?

If your racing turns a profit, you don’t just owe income tax on it — you also owe self-employment tax, which covers Social Security and Medicare. The SE tax rate is 15.3% — 12.4% for Social Security plus 2.9% for Medicare.

Two numbers to know:

• You file Schedule SE if your net self-employment earnings were $400 or more, per the IRS.
• The 12.4% Social Security portion applies only up to a wage base cap that is adjusted annually — the Social Security Administration states it is $184,500 for 2026. The 2.9% Medicare portion has no cap.

The small mercy: you can deduct the employer-equivalent half of your SE tax when figuring your adjusted gross income, per the IRS. For most grassroots racers this is academic — you’re more likely showing a loss than a big profit — but if you have a good year, this is the tax that surprises people. Rates and caps change annually; confirm the current-year figures with your tax pro.

Why does Schedule C only work if you’re a business, not a hobby?

Everything above assumes one thing: the IRS considers your racing a business. If it decides you’re a hobbyist, the whole picture changes — hobby income is still taxable, but hobby expenses generally can’t offset it the way business expenses do — the IRS says a loss from an activity not carried on for profit can’t offset other income. No Schedule C loss to carry to your 1040.

The line comes down to profit intent and how you operate — do you run it like a real business, keep books, and genuinely try to make money? That’s a big enough topic that it gets its own post. Before you file a Schedule C, read Racing: Business or Hobby? and be honest about which side you’re on. Filing a business loss you can’t defend is how audits start.

The clean season report your tax pro wants

Your tax preparer is fast and cheap with clean numbers, and slow and expensive with a shoebox. What “clean” means for a racer:

• Income totaled by type — purse, contingency, sponsorship, separated.
• Expenses totaled by Schedule C category — already sorted into the lines above.
• Receipts kept and organized — the IRS’s general rule is to keep records for at least three years, longer in some situations. If you deduct it, you should be able to prove it.
• A mileage log for the tow rig.
• Big purchases listed separately with dates and amounts, so depreciation can be figured.

Hand your pro that, and Schedule C nearly fills itself out. Hand them a bag of gas receipts and a “trust me, I spent a lot,” and you’re paying them to do your bookkeeping at tax-prep rates.

Your filing-prep checklist

Do this through the season, not the night before:

1. Decide up front whether you’re running as a business — read the business-vs-hobby post and talk to a pro.
2. Log every dollar in as it arrives: purse, contingency, sponsorship, 1099s.
3. Log every dollar out and tag it to a Schedule C category the same week.
4. Keep the receipt — photo or paper — attached to the expense.
5. Track tow-rig miles every tow, or save fuel/service receipts if you’re going actual.
6. Flag big purchases (car, engine, trailer) separately for depreciation.
7. Total everything by category at season’s end.
8. Hand the clean report to your tax professional — and let them file it.

Frequently Asked Questions

Do I report racing winnings if I didn’t get a 1099?

Yes. Income is taxable whether or not a form was issued. The IRS treats your gross receipts as everything your racing took in — purse, contingency, and sponsorship — regardless of paperwork. A missing 1099 doesn’t remove the income; it just means your records and the IRS’s records won’t match if you leave it off. When in doubt, report it and ask your tax pro.

Can I deduct my race car and trailer on Schedule C?

Usually, but not all at once. Big-ticket assets like a race car, engine, or trailer are typically depreciated over several years on Line 13, rather than written off in a single season — though Section 179 rules can sometimes allow a larger up-front deduction. The specific treatment depends on the asset and current tax law, so this is a call to make with your tax professional.

What’s the difference between racing as a business and a hobby on my taxes?

A business files Schedule C and can use expenses to offset income, potentially creating a deductible loss. A hobby must still report income but generally can’t deduct expenses against it. The IRS looks at profit intent and how you operate. It’s a consequential distinction — read our full Business or Hobby? post before you file.

Do I owe self-employment tax on my racing?

If your racing is a business and nets $400 or more in profit, you generally owe self-employment tax — 15.3%, per the IRS. It funds Social Security and Medicare. Most grassroots racers show a loss and never hit it, but a profitable season triggers it. You can deduct half of the SE tax when figuring your adjusted gross income.

Do I need an accountant, or can I file Schedule C myself?

You legally can file it yourself, but racing taxes get complicated fast — depreciation, business-vs-hobby, self-employment tax, and mileage all have gray areas. A tax professional who understands small-business returns usually saves you more than they cost and keeps you defensible if you’re ever questioned. This post is education to make you a better-prepared client, not a substitute for that pro.

Do It the Easy Way With RaceTrips

You can absolutely do all of this by hand. A binder, a spreadsheet, and the discipline to log every entry fee and gas receipt will get you a clean Schedule C. Plenty of racers do exactly that. But if you’d rather turn wrenches than sort receipts in April, that’s what RaceTrips is built for.

• Log income and expenses in categories that already map to Schedule C — so purse, tires, fuel, and travel land in the right buckets from the start, not the night before filing.
• Scan receipts at the track and attach them to the expense, so your documentation is done the moment you spend the money.
• Generate a Tax Summary labeled “Schedule C, Profit or Loss From Business” — the exact report your tax pro wants, organized by line.
• Build custom reports and run a taxable-income calculator to see where your season actually stands before you sit down with your preparer.

Generate a Schedule-C-ready season summary with RaceTrips Premium — start here. Then keep reading: Racing: Business or Hobby?, Racing Tax Deductions, and Run Your Racing Like a Business. Line 9 of that form is car and truck expense, which is its own decision — the racing mileage deduction. The biggest line most racers get wrong is the car itself — race car depreciation and Section 179.

RaceTrips does the sorting. Your tax professional still files the return.
