You just won. Maybe it was a weekend hackathon, a sweepstakes you entered on a whim, or the raffle drawing at a conference. The confetti is still in your hair — and the IRS already has its hand out. Here is the part nobody puts on the giant novelty check: almost every prize you win in the United States is taxable as ordinary income, at its full fair market value, in the year you receive it. A $10,000 prize can easily cost you $2,200 or more in federal tax alone, and a "free" car can arrive with a five-figure tax bill.

This guide explains how prize taxation actually works, what changed for 2026, why the value on your tax form is often inflated, when tax gets withheld before you ever touch the money, and the single clean way to say "no thanks" and owe nothing.

The One Rule: Every Prize Is Ordinary Income

Section 74(a) of the tax code states the rule in one blunt sentence: prizes and awards are part of your gross income. IRS Publication 525 spells out what that covers — lucky-number drawings, television and radio quiz programs, beauty contests, photography contests, and every other event where you win something. Cash, cars, trips, gift cards, merchandise, event tickets, crypto: if you won it, you report it.

Three details matter more than people expect:

Noncash prizes are taxed at fair market value. You do not report what the sponsor claims the prize is worth. You report what the item would sell for on the open market — the standard the regulations call fair market value (FMV). That distinction is worth real money, as the next sections show.

You report it in the year you receive it, on Schedule 1. Prize income lands on Schedule 1 (Form 1040), line 8i, as other income. It is taxed at your ordinary marginal rates, exactly like wages — it just never had withholding taken out of it first (usually).

Your basis in a prize is what you reported. If you win a car, report $28,000 of FMV as income, then sell the car a year later for $24,000, you have a $4,000 nondeductible personal loss — you cannot deduct it, but you also do not get taxed twice. Keep the paperwork showing what you originally reported, because that number becomes your cost basis.

The 2026 Change: No 1099 Under $2,000 — But You Still Owe the Tax

For prizes awarded after December 31, 2025, the One Big Beautiful Bill Act (OBBBA) raised the Form 1099-MISC reporting threshold for prizes and awards from $600 to $2,000, with automatic inflation adjustments starting in 2027. Prizes awarded during calendar year 2025 stayed under the old $600 line.

Here is what the new threshold changes in practice:

  • Sponsors only issue 1099-MISC (Box 3, Other Income) when your calendar-year prizes from them total $2,000 or more. Win $1,500 in one contest and $600 in another contest from the same sponsor in the same year, and the combined $2,100 crosses the line — a form is required.
  • Sponsors generally stop collecting Social Security numbers for smaller wins. No reporting obligation means no W-9 chase for prizes of $1,999 or less, which is most of why sweepstakes sponsors celebrated the change.
  • The January 31 deadline still applies. When a form is required, the sponsor sends your copy by January 31 of the following year and files with the IRS by the end of February.

And here is what the new threshold does not change: your tax bill. The fair market value of a prize is taxable income whether or not anyone sends you a form. Sponsors are still expected to keep records of every prize and every winner, including below-threshold ones. If you won $1,200 across three small contests and received zero paperwork, you still owe tax on $1,200. "I never got a 1099" is not a defense — it is an audit story.

Why the Number on Your 1099 Is Often Too High

Sweepstakes rules always list an "approximate retail value" (ARV) for each prize, and sponsors typically report that same ARV on your 1099-MISC. The ARV is marketing, not appraisal. It is routinely set at full sticker price: the car's MSRP before dealer discounts, the trip priced at peak-season rack rates with every optional excursion included, the merchandise bundle at list price. Your tax, however, is legally based on fair market value — what the prize would actually sell for.

The gap can be enormous. A trip with a $9,000 ARV might be bookable by an ordinary traveler for $5,500. A car with a $32,000 MSRP might change hands at local dealers for $28,000. On a $3,500 overstatement, a winner in the 22 percent bracket overpays by $770 — before state tax.

If your 1099 overstates the value, work through these steps in order:

  1. Ask the sponsor for a corrected 1099-MISC first. Send them your evidence — dealer quotes, bookable airfare and hotel prices for equivalent dates, advertised prices for the identical item — and request a correction. Some sponsors fix it.
  2. If they refuse, report the 1099 amount and back out the difference. Tax software handles this with a fair-market-value adjustment: you enter the Box 3 figure so it matches IRS records, then enter a negative adjustment labeled as a prize FMV adjustment for the overstatement. You pay tax on the real value.
  3. Document everything and keep it for at least three years. Screenshots of comparable prices, written quotes, your letter to the sponsor. If the IRS ever asks why your return differs from the 1099, this file is your answer.

One caution: the adjustment has to be honest. FMV is what a willing buyer would pay a willing seller — not the lowest price you could find anywhere, not what you personally would have paid, and not zero because you "didn't really want it." Shave the inflation, not the value.

When Tax Gets Withheld Before You Touch the Prize

Most contest and sweepstakes prizes arrive with zero withholding, which surprises winners the following April. But several situations do take tax off the top:

Gambling winnings over $5,000 face 24 percent withholding. Lottery payouts, raffle jackpots, casino wins, and poker tournament proceeds reported on Form W-2G are generally subject to 24 percent federal withholding when the proceeds exceed $5,000. States often layer their own withholding on top. That 24 percent is only a prepayment — your final bill depends on your total income and bracket, so big winners frequently owe more at filing time.

Backup withholding hits 24 percent when paperwork is missing. If you win a reportable prize and fail to furnish a correct taxpayer identification number, the payer must impose 24 percent backup withholding. This is the expensive way to protect your Social Security number: give the sponsor a W-9 when asked.

Employee awards go through payroll. Cash bonuses and prizes your employer gives you for performance or suggestions are wages — reported on Form W-2 with income tax withholding plus Social Security and Medicare tax. Only certain noncash achievement awards escape: tangible personal property (not cash or gift cards) given for length of service or safety achievement, capped at $1,600 for qualified plan awards and $400 otherwise, with strict rules about meaningful presentation and who qualifies.

No withholding means you may owe estimated tax. A $25,000 prize added to your ordinary income can push you into a higher bracket and trigger an underpayment penalty if you wait until April to settle up. After a big win, either bump your W-4 withholding for the rest of the year or make an estimated payment. The IRS does not care that the income arrived as a surprise.

The One Way Out: Refuse It Before You Touch It

Publication 525 contains a six-word escape hatch: "If you refuse to accept a prize, don't include its value in your income." That is the entire rule, and it is narrower than it looks.

A valid refusal has to be complete and timely. You must decline the prize before you use it, spend it, deposit it, take delivery of it, or exercise any control over it. Decline in writing, keep a copy, and never take possession. Once you have accepted the prize — driven the car, taken the trip, cashed the check — the income is yours, and giving it away afterward is just a gift or donation with its own separate tax treatment. (If you accept a prize and then donate it to charity, you still report the FMV as income first; you can only deduct the donation if you itemize, subject to the usual limits.)

There is exactly one way to have a prize redirected without ever touching it and owe nothing: the section 74(b) exclusion for certain civic-achievement prizes. It requires all three of these to be true:

  1. You were selected without any action on your part to enter the contest or proceeding.
  2. You are not required to perform substantial future services as a condition of receiving it.
  3. The payer transfers the prize directly to a government unit or tax-exempt charity you designate, under a written designation referencing section 74(b)(3) — made before the prize is presented, or with the prize returned untouched if the presentation was a surprise.

That is the Nobel and Pulitzer lane. Your hackathon victory, sweepstakes win, or game-show appearance required you to enter, so it cannot qualify. For ordinary winners, the real choice is simpler: accept the prize and pay tax on its fair market value, or refuse it cleanly and pay nothing.

When does refusing make sense? When the tax exceeds the value to you. Winners regularly decline trips they cannot schedule, cars they cannot afford to insure and pay tax on, and merchandise they would never buy. A $30,000 car you do not want can easily carry a $7,000-plus combined federal and state bill — declining is sometimes the profitable move. If a prize bundles cash with goods or a trip, ask the sponsor whether you can decline just one component; many allow it.

The Hackathon Twist: When Prize Money Becomes Self-Employment Income

A one-off win is "other income" — no self-employment tax, no Schedule C. But the treatment changes if competing is your business. If you enter hackathons, coding competitions, or contests regularly and continuously with a genuine profit motive, the IRS can treat your winnings as self-employment income: reportable on Schedule C and subject to the 15.3 percent self-employment tax on top of income tax.

That sounds worse, and on the tax side it is — but business treatment unlocks deductions a casual winner never gets. Entry fees, travel to competitions, lodging, specialized hardware and software, cloud compute for your builds: as a business, those are ordinary and necessary expenses that offset the winnings. As a hobbyist, your costs are simply gone — hobby expenses are not deductible against prize income, so a weekend warrior who spends $2,000 chasing a $3,000 prize pays tax on the full $3,000.

Be honest about which side of the line you are on. Occasional entries with no real expectation of profit are a hobby no matter how much you spent. But if you are systematically entering paid competitions, maintaining skills and equipment for that purpose, and showing profits in some years, keep business-grade books from day one — separate accounts, receipts for every competition expense, and contemporaneous records of time and travel. The profit-motive question is always decided on facts, and facts live in your records.

Do Not Forget Your State

Nearly every state with an income tax follows the federal lead and taxes prizes as ordinary income. A few wrinkles catch winners off guard:

  • You can owe tax where you won, not just where you live. Win a prize in a state other than your home state, and the source state may claim the income. Your home state typically offers a credit for taxes paid elsewhere, but you may have to file a nonresident return to sort it out.
  • State withholding rules differ. Some states require withholding on large gambling and prize payouts at their own rates and thresholds.
  • A handful of states have no individual income tax at all. If you live in one, your prize still faces the full federal bill — the state break only removes one layer.

Check your own state's rules before you spend the winnings. The federal guidance in this article is the floor, not the ceiling.

Keep Records Like the 1099 Never Comes

Because the 2026 reporting threshold means fewer small wins generate paperwork, your own records are now your only proof of what you won — and what it was really worth. For every prize, save the award notification, the official rules showing the ARV, your 1099-MISC if one arrives, your FMV comparables if you dispute the value, any written refusal, and receipts for competition expenses if you compete as a business. Log each win as other income in your books in the year received, with the source documents attached, so next April is a lookup instead of an archaeology project.

If you track your finances in plain-text accounting, a prize is just another dated transaction with a paper trail — record the FMV as income when received, link the award letter and 1099, and the audit file builds itself. The Beancount documentation walks through setting up income accounts and attaching source references if you are starting from scratch.

Keep Your Windfall (and Everything Else) Organized

Winning is the fun part; the paperwork is where winners lose money they did not have to lose — overpaying on inflated values, missing the estimated-tax deadline, or failing to document the expenses that offset a professional competitor's income.
