Federal Wagering Excise Tax

Every legal sports bet accepted by a licensed sportsbook in the United States carries a federal excise tax — 0.25% of the wager if the bet is accepted in a state where sports wagering is authorized, and 2% for all other wagers. This tax, along with a $50/year federal occupational tax on each person who accepts wagers commercially, has existed since the 1950s and predates the Supreme Court's 2018 Murphy decision that opened the door to state-regulated sports betting. Tribal casinos that operate under the Indian Gaming Regulatory Act (IGRA) are subject to the same wagering excise. The tax is modest compared to state tax structures, but it is unavoidable and applies to every wager accepted — win or lose. Casinos, online sportsbooks, and any other entity in the business of accepting wagers must register with the IRS and file monthly tax returns on gross wager volume.

Current Law (2026)

Legal Authority

• 26 U.S.C. § 4401 — Imposes excise tax on wagers: 0.25% if accepted in a state where the wagering is authorized under state law; 2% for unauthorized wagers; total wager amount (including all incident charges) is the tax base
• 26 U.S.C. § 4402 — Exemptions: parimutuel enterprises licensed under state law; coin-operated devices; state lotteries; certain amounts paid by lottery operators to other licensed lottery operators
• 26 U.S.C. § 4403 — Record requirements: each person liable must keep daily records of gross wager amounts, in addition to general § 6001 records
• 26 U.S.C. § 4411 — Occupational tax: $500/year special tax per person liable for § 4401 excise; reduced to $50/year if the person only accepts wagers authorized under state law
• 26 U.S.C. § 4412 — Registration: each person subject to the occupational tax must register with IRS, disclosing name, residence, each place of business, and (for agents accepting wagers on behalf of others) identity of the principal
• 26 U.S.C. § 4421 — Definitions: "wager" means any bet on a sports event or contest with a person in the wagering business; any wager in a for-profit wagering pool; any wager in a for-profit lottery; "lottery" includes numbers, policy, and similar games
• 26 U.S.C. § 4422 — Federal/state coexistence: federal excise payment does not exempt anyone from state law penalties for the same activity, and states may impose their own taxes on identical activity
• 26 U.S.C. § 4424 — Confidentiality of wagering tax information: the IRS may not disclose wagering returns or payment records to any person, including state law enforcement, except as specifically provided — a provision that has historically complicated coordination between IRS and state gambling enforcement

Implementing Regulations

The IRS regulations implementing the federal wagering excise live at 26 CFR Part 44 — Taxes on Wagering. Key provisions:

• § 44.4401-1 — Imposition of the wagering excise: the tax of 0.25% (authorized wagers) or 2% (unauthorized wagers) attaches to "all wagers" as defined in § 4421 — bets on sports events or contests accepted by a commercial bookmaker, bets in a for-profit wagering pool, and bets in a for-profit lottery. The tax base is the amount of the wager including all charges "incident to" placing the bet. Promotional free bets provided by the operator are generally not a "wager" because the bettor risks nothing of value.
• § 44.4401-2 — Person liable: the person accepting the wager is the taxpayer — sportsbook operators, pool operators, and lottery operators. Bettors have no liability for the excise tax. When an agent accepts wagers on behalf of a principal, both the agent and principal may be jointly liable.
• § 44.4401-3 — When tax attaches: the excise attaches at the moment the person engaged in the wagering business accepts the wager (or the lottery contribution is received). The tax is not contingent on the outcome of the bet — a wager that is later voided or refunded does not reduce liability already incurred unless the regulations provide specific credit treatment.
• § 44.4402-1 — Exemptions: (1) parimutuel wagering enterprises licensed under state law (horse racing tracks, greyhound tracks) — the parimutuel pool is exempt regardless of amount; (2) coin-operated wagering devices; (3) state-operated lotteries — entirely exempt (this is why Powerball and Mega Millions are not subject to the § 4401 excise); (4) amounts received by lottery operators from other licensed lottery operators for joint operations.
• § 44.4404-1 — Territorial extent: the tax applies to wagers (a) accepted in the United States, regardless of where the bettor is located; or (b) placed by a person who is in the United States with a bookmaker who is a U.S. citizen or resident; or (c) placed from inside the U.S. with any foreign bookmaker if the wager is on a sports event or contest occurring in the U.S. This means U.S. residents betting on U.S. sporting events through offshore books trigger U.S. excise liability — even though collection is practically difficult.
• § 44.4411-1 — Occupational (special) tax: a $50/year occupational tax for each person who accepts wagers authorized under state law (or on behalf of such a person); $500/year for all other persons accepting wagers commercially. This is a flat per-person per-year fee independent of wager volume. Partners and officers who personally accept wagers each owe the occupational tax; the business entity itself does not owe a separate occupational tax if the individuals liable have registered.
• § 44.4412-1 — Registration: every person who owes the occupational tax (i.e., every commercial wager-acceptor) must register by filing Form 11-C (Occupational Tax and Registration Return for Wagering) before commencing wagering operations. Form 11-C requires: name, address, employer identification number, type of wagering operation, each place of business, and — for agents — the name and address of the principal. The occupational tax stamp issued on Form 11-C must be kept at the principal place of business.
• § 44.4421-1 — Definition of "wager": the operative term. A wager is: (1) any bet with a commercial bookmaker on the outcome of a sports event or contest; (2) any wager placed in a for-profit wagering pool (e.g., private season-long pools run for a fee); (3) any wager in a for-profit lottery. Private, non-profit wagering — office pools with no rake, friendly bets between individuals — does not meet this definition and is not subject to the excise.
• § 44.4422-1 — Doing business in violation of law: paying the federal occupational tax and registering with the IRS does not legalize wagering that is illegal under state or federal law. The federal tax obligation and state licensing requirements are independent; a bookmaker in an unlicensed state owes federal excise at 2% (unauthorized rate) AND remains subject to state criminal liability.

The compliance mechanics: monthly filing on Form 730 (Monthly Tax Return for Wagers) reporting total wagers accepted in the prior month; due the last day of the month following the tax period (e.g., January wagers due February 28). Electronic filing is mandatory for large operators. The occupational tax is paid annually on Form 11-C. Both forms are filed with the IRS at the Cincinnati Service Center.

How It Works

The federal wagering excise is assessed on gross wagers accepted, not on net win or profit. This matters enormously to operators: a sportsbook that accepts $1 million in bets and pays out $980,000 in winnings has $20,000 in gross revenue — but it owes $2,500 in federal excise on the full $1 million of wagers (at 0.25%). The tax is on the action, not the margin.

The tax liability falls entirely on the entity accepting the wager — the sportsbook, the bookie, the card room running a for-profit tournament. Bettors pay nothing directly, though operators model the tax into their pricing when setting odds and hold percentages. The 0.25% rate applies when wagering activity is authorized under the law of the state where the bet is accepted; since the Supreme Court's 2018 ruling in Murphy v. NCAA struck down the federal prohibition on state sports betting laws, the majority of U.S. sports bets are now accepted in states that have authorized sports wagering and thus qualify for the lower rate. Illegal bookmaking operations accepting unauthorized wagers owe the higher 2% rate — though collection is obviously difficult given the underground nature of those operations. Anyone accepting wagers commercially must also register with the IRS and pay the occupational tax ($50 or $500/year depending on authorization status). Registration was originally designed as a tool to identify illegal gambling operations — Congress reasoned that an illegal bookie was unlikely to register, creating a catch-22 where not registering was itself a crime. This logic was challenged but largely upheld by courts.

The § 4424 restriction on IRS sharing wagering tax information with state authorities was designed to prevent the federal registration system from becoming an informant tool against state gambling laws — it creates ongoing tension with state enforcement efforts in jurisdictions where certain wagering remains illegal, and has become more complicated as state-by-state legalization has created a patchwork of authorized and unauthorized wagering across state lines.

How It Affects You

If you operate a licensed sportsbook, cardroom, or other taxable wagering business: Your federal wagering excise compliance centers on IRS Form 730 (Monthly Tax Return for Wagers). You file monthly — reporting gross wagers accepted in the prior calendar month — and remit 0.25% of that handle (for state-authorized wagering) or 2% of handle (for unauthorized wagering) to the IRS. The filing deadline is the last day of the month following the tax period: January wagers are due February 28. You also owe the $50/year occupational tax for each person accepting wagers on your behalf (26 U.S.C. § 4411) — in a large operation with dozens of shift supervisors and tellers, this adds up. For a sportsbook accepting $100 million in monthly wagers, that's $250,000/month in federal excise (before the far larger state tax, which in New York is 51% of gross gaming revenue — roughly $20–$40M/month on the same volume). Failure to file or pay triggers standard IRS penalties (5% per month on unpaid tax, up to 25%) plus criminal liability under 26 U.S.C. § 7203 for willful failure to file. IRS Form 730 instructions and filing guidance are at irs.gov/forms-pubs/about-form-730.

If you bet on sports, horse racing, or play in casinos: You don't pay the wagering excise tax — that's the operator's obligation, built into the house's edge. But you do owe federal income tax on all gambling winnings regardless of amount (26 U.S.C. § 61). Sportsbooks and casinos must issue you a Form W-2G and withhold 24% federal income tax automatically if: your winnings exceed $600 and your odds were 300:1 or greater, your winnings exceed $1,200 from slot machines or bingo, or your winnings exceed $5,000 from poker tournaments. Even if no W-2G is issued — because your winnings fall below these thresholds — you still owe income tax on every dollar won and must report it on Schedule 1 of your Form 1040. Gambling losses are deductible only if you itemize deductions (not available to standard deduction filers), and only up to the amount of your winnings in the same year — you cannot use excess gambling losses to offset other income. Keep records: date, location, type of game, amount won and lost. The IRS gambling win/loss FAQ is at irs.gov/taxtopics/tc419.

If you run a private sports pool, poker game, or fantasy league with prize money: The federal law draws a line at profit-making. The § 4421 definition of "wager" explicitly exempts "any amount placed in a sweepstakes, wagering pool, or lottery which is conducted for profit" — but private, social pools where no profit is taken fall outside the taxable wager definition. The critical test: if you're taking a rake, vig, or management fee for running the pool, you're likely subject to both the 2% unauthorized wagering excise (since most private pools aren't state-licensed) and the $50 occupational tax per person accepting wagers. Fantasy sports with entry fees and prize payouts occupy a legal gray zone — whether a specific contest constitutes a "wager" depends on the structure and state law. Operators of significant prize-pool fantasy contests (DraftKings, FanDuel) have resolved this via state licensing; informal organizers of large money pools should get legal advice before scaling. The AGA's Responsible Gaming resources at americangaming.org provide background on the federal-state tax interaction for operators in this space.

If you're an investor in or analyst covering gaming companies: The federal excise at 0.25% of handle is a small but certain cost of revenue for U.S. sportsbook operators — it flows through to the P&L as a cost of revenues line, not offset by losses. On $120 billion in estimated 2024 U.S. legal sports betting handle, federal excise generates approximately $300 million in annual federal revenue — relatively modest for the federal government but a meaningful line item for operators at scale. The more financially significant taxes are state-level: New York (51% of GGR), Pennsylvania (36%), and Illinois (up to 40%) impose among the highest effective rates in the world, making those states marginally profitable or unprofitable for operators focused on revenue-share metrics. Track state-by-state rates through the American Gaming Association's State Gaming Report (americangaming.org/research) and the Tax Foundation's gambling tax analysis (taxfoundation.org). The federal rate has been unchanged since the 1950s and periodic proposals to raise it to 1-2% of handle face strong industry opposition.

State Variations

Sports betting tax rates and structures vary enormously by state. New York taxes sports wagering operators at 51% of gross gaming revenue — among the highest in the world. Other states (Nevada, Wyoming) tax at 6.75% of GGR. The federal wagering excise is uniform nationwide and applies on top of whatever state structure exists.

Pending Legislation

No major pending federal legislation on wagering excise rates as of April 2026. The existing structure has remained largely unchanged since the 1950s, though the effective reach of the tax has expanded dramatically as legal sports betting has spread across states following the 2018 Murphy decision.

Recent Developments

• Sports betting has exploded since Murphy — federal excise revenue growing substantially: The Supreme Court's 2018 Murphy v. NCAA decision struck down the Professional and Amateur Sports Protection Act (PASPA), opening the door for state-by-state sports betting legalization. As of April 2026, 38+ states and DC have legalized sports wagering — up from zero commercial operations in 2017. The American Gaming Association estimates legal sports betting volume reached approximately $120 billion in 2024, generating roughly $300 million in annual federal wagering excise revenue (at 0.25% of wagers). By comparison, all wagering excise collected pre-Murphy was primarily from horse racing and illegal market operators that registered anyway.
• Online sportsbooks dominate the legal market — IRS compliance has become a major issue: DraftKings, FanDuel, BetMGM, Caesars, and their competitors now accept the vast majority of legal sports wagers digitally. The federal wagering excise and occupational tax compliance obligations require each licensed operator to register all personnel who accept wagers and file monthly Form 730 returns on gross wager volume. IRS compliance examination activity targeting online sportsbooks has increased since 2019, focusing on correct wager characterization (promotional free bets are not wagers), exclusion of state lottery and parimutuel operations from taxable amounts, and occupational tax registration completeness across multi-state operations.
• California voted twice against sports betting — largest market remains closed: Despite two ballot initiatives (2022, 2024), California voters rejected both tribal-backed and commercial sports betting legalization. California is the largest U.S. sports market by population; its ongoing absence from the legal market means roughly 12% of the U.S. population remains without state-regulated access. Illegal offshore and unlicensed sportsbooks continue to operate in California; these operators either register with the IRS and pay the 2% (unauthorized wager) rate, or ignore federal requirements entirely — an IRS enforcement gap.
• Offshore illegal market remains large — federal excise is rarely collected from it: The American Gaming Association estimates the illegal online sports betting market — consisting primarily of offshore bookmakers operating without U.S. licenses — handles $64+ billion in annual wagers. These operators do not register with the IRS or pay the federal wagering excise. Federal criminal prosecution under 18 U.S.C. § 1955 (illegal gambling businesses) and the Wire Act captures some offshore operators, but systematic IRS wagering excise collection from the illegal market is minimal. The legal market's rapid growth is narrowing (but not eliminating) this gap.
