Gambling Taxes 2026: Federal Rules for Every Vertical

Last Updated: July 18, 2026

Yes — every dollar you win gambling is taxable income under federal law, whether it came from a sportsbook, a poker table, a prediction market, or a casino. The IRS taxes it all as ordinary income (10%-37%), states add up to 13.3% more, and the 2026 OBBBA caps loss deductions at 90% of winnings for itemizers.

This guide covers the federal tax framework that applies across all gambling verticals, the reporting forms you’ll encounter, the OBBBA loss deduction cap, professional vs. recreational classification, state-level considerations, and record-keeping requirements. Each section links to our vertical-specific guides for deeper coverage. For personalized numbers, run your figures through our gambling tax calculator.

How Does the IRS Tax Gambling Income?

The IRS taxes gambling winnings as ordinary income under IRC Section 61. This means your gambling profits are added to your wages, investment income, and other earnings, then taxed at your marginal rate. There is no special capital gains treatment for recreational gamblers.

The federal tax brackets for 2026 single filers:

If you earn $60,000 from your job and win $5,000 gambling, that $5,000 is taxed at your marginal rate of 22%. Your effective tax on the gambling winnings: $1,100 federal, plus state taxes.

Gambling losses can offset gambling winnings, but only up to the amount of winnings (you cannot create a net gambling loss to offset other income), and only if you itemize on Schedule A. The 2026 OBBBA legislation added a further restriction on top of that, detailed below.

What Forms Will I Receive?

Different gambling verticals trigger different IRS reporting forms. Platforms are required to issue these forms when your winnings exceed certain thresholds. Critically, you owe taxes on ALL gambling income — not just amounts reported on forms.

The “none issued” category is where most people make mistakes. Polymarket operates offshore and does not report to the IRS. Neither do most sweepstakes casinos for small amounts. You are still legally obligated to report this income. The IRS can and does cross-reference bank deposits, crypto wallet activity, and exchange records during audits.

W-2G Thresholds by Vertical

The W-2G reporting thresholds vary significantly across gambling types. Understanding when a form is triggered helps you anticipate your tax paperwork, but remember — the threshold is for reporting, not for taxation. A $500 sports bet payout is taxable even though no W-2G is issued.

• Slots and bingo: $1,200 or more in winnings from a single session
• Keno: $1,500 or more (reduced by the wager amount)
• Poker tournaments: $5,000 or more in net winnings (buy-in is subtracted)
• Horse racing and sportsbooks: $600 or more AND the payout is at least 300x the wager
• Lottery: $600 or more

For sports betting specifically, the 300:1 odds requirement means most parlays and standard bets won’t generate a W-2G unless the odds were extreme. A $10 parlay paying $3,500 at 350:1 triggers a W-2G. A $100 moneyline bet paying $800 at 8:1 does not — but you still owe taxes on the $700 profit.

What Is the OBBBA 90% Loss Deduction Cap?

The Online Betting and Bingo Benefits Act (OBBBA), effective January 1, 2026, is the most significant change to gambling taxation in decades. It caps the gambling loss deduction at 90% of winnings for taxpayers who itemize on Schedule A — the only route through which gambling losses have ever been deductible.

OBBBA didn’t change who can deduct losses; you still must itemize to claim any gambling loss deduction, same as before. What changed is the ceiling: itemizers used to be able to deduct losses up to 100% of winnings. Now the deduction tops out at 90%, which creates taxable “phantom income” even in a break-even year.

How the 90% Cap Works

The cap only bites when your losses reach or exceed 90% of your winnings. A bettor who wins $10,000 and loses $12,000 nets a real loss, but OBBBA still taxes $1,000 of income — the gap between 90% and 100% of winnings. Run your own numbers through the gambling tax calculator to see the phantom-income effect at your figures.

The cap applies to sports betting, casino, and poker losses reported on Schedule A, and to prediction market profits if you classify them as gambling income. It does not apply to DFS winnings, which are reported as “Other Income” on Schedule 1 rather than gambling income — and it does not apply to professional gamblers filing Schedule C, who deduct losses and business expenses without any cap. See our poker tax guide for how the cap interacts with the session method.

How Are Prediction Market Profits Taxed?

Prediction market taxation is the most unsettled area in gambling tax law. The IRS has not issued definitive guidance on how event contracts should be classified. Three competing theories exist, and the correct treatment may depend on the platform, contract type, and your filing status.

Affiliate disclosure: OddsReference may earn a commission if you sign up through the Kalshi link below. See our affiliate disclosure for current partnership status — partnerships never affect our editorial content.

Theory 1: Gambling income. Treat prediction market profits as gambling winnings on Schedule 1 (or Schedule A for loss deductions, subject to the OBBBA 90% cap). This is the simplest approach and how most individual traders file. Kalshi issues 1099-MISC forms for net income above $600, consistent with this treatment.

Theory 2: Short-term capital gains. Treat event contracts as securities and report on Schedule D. This classification could apply to CFTC-regulated contracts (Kalshi’s are CFTC-approved). Capital gains treatment allows netting gains and losses without the OBBBA cap, but all short-term gains are taxed at ordinary income rates anyway.

Theory 3: Section 1256 contracts. CFTC-regulated contracts may qualify for Section 1256 treatment (60% long-term / 40% short-term capital gains, regardless of holding period). This produces a blended rate lower than ordinary income for most taxpayers. No exchange currently issues 1099s on this basis, and applying Section 1256 to event contracts is aggressive.

Polymarket does not report to the IRS. If you trade on Polymarket, you are responsible for tracking all deposits, withdrawals, and trade-level P&L, and self-reporting on your return. Keep your full trade history — Polymarket exports via CSV are the minimum documentation standard.

Our prediction market tax guide covers the classification theories, Kalshi vs. Polymarket reporting differences, and practical filing strategies in depth. Note that whether you can legally trade at all depends on your state — prediction market legality is actively litigated in roughly 20 states, tracked on our state-by-state legal tracker.

How Is DFS Income Taxed?

Daily fantasy sports platforms like DraftKings and FanDuel issue 1099-MISC forms when your net income exceeds $600 in a calendar year. DFS winnings are reported on Schedule 1 (Line 8b, “Other income”) and are subject to federal income tax at your marginal rate.

DFS is classified as “Other Income,” not gambling income, so it does not follow the Schedule A gambling-loss rules and is not subject to the OBBBA 90% cap. Recreational players’ options for deducting DFS losses against DFS winnings are limited under this classification; professional DFS players filing Schedule C can deduct losses and business expenses in full. DFS losses from one platform can offset DFS winnings from another platform — the IRS looks at your total DFS activity, not platform-by-platform results.

One common trap: DraftKings and FanDuel calculate net income differently for 1099 purposes. DraftKings reports your total withdrawals minus total deposits. FanDuel uses net winnings across contests. These can produce different 1099 amounts even if your actual P&L is identical. If you receive 1099s from multiple platforms, reconcile them against your own records before filing.

For pick’em formats specifically, see our pick’em tax guide. For a full breakdown of DFS tax rules, see our DFS tax guide.

How Are Casino Winnings Taxed?

Online casino and sweepstakes casino tax rules follow the standard gambling income framework with one important distinction: sweepstakes casinos use virtual currencies (Gold Coins, Sweeps Coins) that convert to real prizes.

The IRS taxes sweepstakes casino winnings when you redeem virtual currency for cash or prizes — not when you win the coins. A player sitting on 50,000 unredeemed Sweeps Coins owes nothing until redemption. Once redeemed, the cash value is taxable gambling income.

Traditional online casinos (iCasinos, legal in NJ, PA, MI, WV, CT, DE, RI) issue W-2Gs for slot wins above $1,200 and table game wins above the applicable thresholds.

For details on sweepstakes vs. iCasino tax treatment, see our online casino tax guide and sweepstakes casino tax guide.

How Are Lottery Winnings Taxed?

Lottery winnings above $600 trigger W-2G reporting. Federal tax on lottery jackpots is withheld at 24% at the time of payout, but your actual tax liability is calculated at your marginal rate (up to 37% for jackpots that push you into the top bracket).

State lottery taxes vary from 0% (Florida, Texas, Wyoming, and others) to 10.9% (New York). The difference is substantial: a $100 million Powerball jackpot nets approximately $37.5 million after-tax in Florida versus $32.1 million in New York.

Should I File as a Professional Gambler?

Professional gambler status (Schedule C filing) changes the tax calculus significantly. The benefits are real, but so are the costs. Understanding the tradeoffs is essential before making this election.

Benefits of Professional Status

Costs of Professional Status

The IRS “Trade or Business” Test

The IRS uses a multi-factor test from Commissioner v. Groetzinger (1987) to determine professional status:

1. Frequency and regularity. Do you gamble regularly and systematically, not just occasionally?
2. Profit motive. Do you approach gambling with a genuine intent to earn a living?
3. Time and effort. Do you devote substantial time to gambling activities?
4. Expertise. Do you study, research, and develop strategies?
5. Dependence on income. Is gambling a significant source of your income?
6. Losses indicate business. A long history of losses may suggest hobby, not business.

No single factor is determinative. The IRS looks at the totality of circumstances. A poker player who plays 40 hours per week, maintains detailed session logs, studies game theory, and earns 70% of their income from poker has a strong case. A weekend sports bettor who loses more than they win does not.

For poker-specific professional status rules (including the session method under Rev. Proc. 2015-53), see our poker tax guide.

What Records Should I Keep?

The IRS expects gamblers to maintain contemporaneous records of all gambling activity. “Contemporaneous” means recorded at or near the time of the activity — not reconstructed from memory months later.

Minimum Record-Keeping Requirements

For each gambling session or transaction, document:

• Date and time of the activity
• Type of gambling (sports bet, poker session, prediction market trade, DFS contest)
• Platform or venue name
• Amount wagered and amount won or lost
• Running balance of wins and losses for the year

Platform-Specific Documentation

For Polymarket and other offshore platforms that don’t report to the IRS, your records are your only defense in an audit. Export your full trade history at least quarterly and store it securely. Blockchain records (wallet transactions, contract interactions) provide an immutable secondary record.

Keep all gambling tax records for at least three years from the filing date (the standard IRS audit window). If you report income exceeding $100,000 from gambling or file as a professional, consider keeping records for six years (the extended audit window for substantial understatements).

What About State Gambling Taxes?

State tax treatment varies significantly. Nine states have no state income tax (Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, Wyoming), which means no state tax on gambling winnings. The remaining states tax gambling income at their standard income tax rates, ranging from roughly 1% to 13.3%.

States With Notable Gambling Tax Rules

Some states follow federal treatment (allowing loss deductions against winnings). Others do not — they tax gross gambling winnings with no loss offset. Check your state’s specific rules before filing.

Our state-by-state legality guide covers which gambling verticals are legal in each state. For lottery-specific state taxes with payout calculators, see our lottery tax pages.

When Should I Hire a Tax Professional?

Self-filing gambling taxes is straightforward for recreational bettors with a single sportsbook account and modest winnings. You report gambling income on Schedule 1 (Line 8b). If you take the standard deduction, you owe tax on full winnings with no loss offset; if you itemize on Schedule A, the OBBBA 90% cap applies automatically to your loss deduction.

Consider hiring a CPA or enrolled agent if any of these apply:

• Your combined gambling income exceeds $10,000 across all platforms
• You trade on platforms that don’t issue tax forms (Polymarket, offshore sportsbooks)
• You’re considering filing as a professional gambler (Schedule C)
• You have gambling income in multiple states (each may require a separate state return)
• You received conflicting 1099s from different platforms for the same activity
• You had significant crypto-denominated gambling winnings (USDC, ETH conversions create additional taxable events)
• You have gambling and investment income that may interact (AMT considerations)

A CPA familiar with gambling taxation typically charges $300-$800 for a return with Schedule C gambling business income. The cost is itself a deductible business expense if you file as a professional.

How Do Crypto-Denominated Winnings Work?

If you trade prediction markets on Polymarket (USDC-denominated) or play at crypto casinos, you face a double tax event. First, your gambling winnings are taxed as ordinary income at the fair market value in USD when received. Second, any subsequent change in the crypto’s value creates a separate capital gain or loss when you convert to fiat.

For example: You win 500 USDC on a Polymarket trade when USDC is pegged at $1.00. That’s $500 of gambling income. If you hold the USDC for 3 months and it’s still worth $1.00 when you sell, there’s no additional capital gain. But if you won 0.5 ETH when ETH was at $3,000 ($1,500 gambling income) and converted to USD when ETH was at $3,500, you have $1,500 gambling income plus $250 short-term capital gain.

USDC and other stablecoins minimize this complexity since they maintain a $1.00 peg. For volatile crypto winnings (ETH, BTC, SOL), track both the fair market value at the time of winning and the value at conversion.

How Do I Report Gambling Income From Multiple Verticals?

If you play sports, poker, DFS, and trade prediction markets, your total gambling activity is aggregated on your tax return. You don’t file separate schedules for each vertical — all gambling income goes on Schedule 1 (Line 8b) for recreational gamblers.

Step-by-Step Filing for Multi-Vertical Gamblers

1. Collect all tax forms — W-2Gs from casinos/sportsbooks, 1099-MISCs from DFS/Kalshi, plus your own records for unreported platforms
2. Calculate net gambling income — Total winnings minus total losses across ALL verticals (combined, not per-platform)
3. Apply the OBBBA 90% cap — If itemizing on Schedule A, cap your loss deduction at 90% of total gambling winnings (sports betting, casino, poker, and gambling-classified prediction market losses; DFS is exempt)
4. Report on Schedule 1 — Line 8b, “Other income,” with a description of “Gambling winnings”
5. Attach W-2Gs — Submit all W-2G forms received with your return
6. Keep records — Retain platform statements, trade histories, and session logs for 3-6 years

If your total net gambling income is negative (losses exceed winnings), you cannot deduct the excess against wages or investment income. Gambling losses only offset gambling winnings — the excess carries no tax benefit.

Frequently Asked Questions

Do I have to pay taxes on small gambling winnings?

Yes. All gambling winnings are taxable regardless of amount. A $50 sports bet payout is legally taxable even though no reporting form is generated. The IRS does not audit every $50 win, but you are legally required to report it. Practically, most recreational bettors report their net annual gambling result — total wins minus total losses — rather than tracking every individual bet.

What happens if I don’t report gambling income?

If the IRS receives a W-2G or 1099 and you don’t report the corresponding income, you’ll receive a CP2000 notice (proposed adjustment) within 12-18 months. Penalties include the tax owed plus interest (currently ~8% annually) plus a 20% accuracy-related penalty. For offshore platform income with no reporting, the risk depends on whether the IRS identifies the income through bank deposit analysis or cryptocurrency chain analytics.

Can I deduct gambling losses if I take the standard deduction?

No. You must itemize on Schedule A to deduct any gambling losses — OBBBA didn’t change that requirement. What OBBBA changed is the ceiling for itemizers: losses that were once deductible up to 100% of winnings are now capped at 90%, starting with tax year 2026 returns.

Are prediction market fees tax-deductible?

For recreational gamblers, platform fees (Kalshi taker fees, gas fees for Polymarket trades) are included in your loss calculation — they reduce your net winnings. For professional gamblers filing Schedule C, fees are deductible as business expenses separate from the gambling P&L.

Do I owe state taxes if I bet in a different state than where I live?

Generally, you owe state tax to your state of residence on all gambling income, regardless of where the activity occurred. Some states also claim tax on gambling income earned within their borders by non-residents. New Jersey and Pennsylvania, for example, tax non-resident gambling winnings from in-state casinos and sportsbooks. You can typically claim a credit on your home state return for taxes paid to other states.

Key Takeaways

• All gambling winnings are taxable income — the IRS does not distinguish between sportsbooks, prediction markets, poker, DFS, casinos, or lottery
• The OBBBA 90% loss cap (effective tax year 2026) caps itemized gambling loss deductions at 90% of winnings — DFS and professional (Schedule C) filers are exempt
• W-2G thresholds vary by vertical ($1,200 for slots, $5,000 for poker, $600 for sportsbooks at 300:1+ odds) — but you owe tax below these thresholds too
• Prediction market tax classification remains unsettled — gambling income (Schedule 1), capital gains (Schedule D), and Section 1256 are all defensible positions
• Polymarket and offshore platforms don’t report to the IRS — self-reporting with detailed records is your legal obligation and your audit defense
• Professional gambler status (Schedule C) unlocks business expense deductions but adds 15.3% self-employment tax and increased audit risk
• Keep platform statements, trade exports, and session logs for 3-6 years minimum
