Gambling Taxes in 2026: The Complete US Guide

Last Updated: March 25, 2026

Every dollar you win gambling is taxable income. The IRS does not care whether you won it on a sportsbook, a prediction market, a poker table, or a slot machine. Federal law treats all gambling winnings as ordinary income, taxed at your marginal rate (10% to 37% depending on bracket). State taxes add another 0% to 13.3% on top. The only question is how you report it and what you can deduct.

This guide covers the federal tax framework that applies across all gambling verticals, the reporting forms you’ll encounter, the 2025 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.

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). The 2025 OBBBA legislation added a further restriction, 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 Accountability Act, signed into law in late 2024, introduced the most significant change to gambling taxation in decades. Starting with tax year 2025 returns (filed in 2026), taxpayers who take the standard deduction can only deduct gambling losses up to 90% of their gambling winnings.

Before OBBBA, if you didn’t itemize, you couldn’t deduct gambling losses at all — you paid tax on gross winnings. OBBBA gave non-itemizers a loss deduction, but capped it at 90%.

How the 90% Cap Works

The cap only matters when your losses exceed 90% of your winnings. If you won $10,000 and lost $12,000, without OBBBA you’d owe tax on the full $10,000 (no deduction for non-itemizers). With OBBBA, you deduct $9,000 and owe tax on $1,000. The cap is an improvement over the old system for most recreational gamblers.

For itemizers using Schedule A, the rules are unchanged — you can deduct gambling losses up to the full amount of gambling winnings. The 90% cap applies only to the OBBBA standard-deduction pathway.

The OBBBA affects every gambling vertical equally. Whether you trade prediction market contracts, play online poker, or use DFS platforms, the same 90% cap applies to your combined gambling losses.

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.

Theory 1: Gambling income. Treat prediction market profits as gambling winnings on Schedule 1 (or Schedule A for loss deductions). 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.

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 losses can offset DFS winnings under the standard gambling loss deduction rules, subject to the OBBBA 90% cap for non-itemizers. DFS losses from one platform can offset DFS winnings from another platform — the IRS looks at your total gambling 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.

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.

We maintain detailed state-by-state lottery tax pages for all 50 states. See our lottery tax calculator for personalized after-tax estimates, or browse state pages like New York lottery taxes, California lottery taxes, or Texas lottery taxes.

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.

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), claim the standard deduction, and the OBBBA 90% cap handles loss deductions automatically.

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 taking standard deduction, cap your loss deduction at 90% of total winnings
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?

Yes, starting with the 2025 tax year (filed in 2026). The OBBBA allows non-itemizers to deduct gambling losses up to 90% of gambling winnings. Before OBBBA, non-itemizers could not deduct gambling losses at all.

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 lets non-itemizers deduct losses up to 90% of winnings starting tax year 2025 — a meaningful improvement over the prior zero-deduction rule
• 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
