The Federal Excise Tax on Sports Bets: Where the 0.25 Percent Goes

Yes, there is a federal tax on each legal US sports bet: 26 U.S.C. § 4401 imposes an excise tax of 0.25 percent of the amount wagered, so a $100 bet carries 25 cents of tax. The sportsbook, not the bettor, is the person the statute makes liable, and it reports and pays the tax every month on IRS Form 730. Wagers that are not authorized by the state where they are accepted are taxed at 2 percent instead.

What does 26 U.S.C. § 4401 actually tax?

Section 4401(a) has two rates, and the dividing line is state law, not federal law:

• § 4401(a)(1): a wager "authorized under the law of the State in which accepted" is taxed at 0.25 percent of the amount of the wager.
• § 4401(a)(2): any other wager is taxed at 2 percent of the amount of the wager.

The tax is on the amount wagered, which the industry calls handle. It is not a tax on the book's profit and not a tax on the bettor's winnings. A $100 bet that loses and a $100 bet that wins carry the same 25 cents.

What counts as a "wager" is set by 26 U.S.C. § 4421. It covers a wager on a sports event or contest placed with a person in the business of accepting such wagers, a wager in a sports wagering pool conducted for profit, and a wager in a lottery conducted for profit. The IRS's Form 730 instructions read "sports event" broadly, listing everything from football and boxing to cards, billiards and horse racing, and read "contest" to include competitions of skill, endurance or popularity such as elections and spelling bees.

Section 4401(b) defines the amount of the wager as including all charges incident to placing it. There is one carve-out: if the operator can show, under Treasury regulations, that it collected an amount equal to the tax from the bettor as a separate charge, that separate charge is not itself part of the taxable wager.

Section 4401(c) names who pays. Each person "engaged in the business of accepting wagers" is liable for the tax on all wagers placed with it, and each person who conducts a wagering pool or lottery is liable for the tax on wagers placed in it. An agent who must register but takes wagers for someone else without registering that person's name and address becomes liable for the tax on those wagers.

How much of a $100 bet goes to the federal excise tax?

The arithmetic is a single multiplication: amount wagered × 0.0025 for an authorized wager, or × 0.02 for an unauthorized one. Because the tax attaches to each wager, the total tax follows total handle, not the bettor's net result.

Two practical points follow from the table.

A parlay is one wager. The tax is on the amount placed, so a $100 parlay carries the same 25 cents as a $100 straight bet, however many legs it has.

The tax is small next to the price of a bet, but it is a fixed share of handle. On a two-way market priced -110 on both sides, a book that takes $110 on each side collects $220 and pays $210 to whichever side wins, keeping $10. That is a theoretical margin of 10 / 220 = 4.545 percent of handle. The excise tax on that $220 at 0.25 percent is $0.55. In other words, of the $10 the book expects to keep from a perfectly balanced -110 market, $0.55, or 5.5 percent, goes to the federal excise tax before any state tax or operating cost. On a lower-margin market the same 0.25 percent of handle takes a bigger share of the margin; on a high-margin parlay it takes a smaller share.

That is why the tax shows up in industry arguments far more than its 0.25 percent headline suggests: it is charged on volume, while the book's revenue is only a few cents on each dollar of volume.

Who files Form 730 and Form 11-C, and when?

Two forms carry the tax.

Form 730, Monthly Tax Return for Wagers. The Form 730 instructions say a person must file and pay the tax under § 4401(a) if it is in the business of accepting wagers, conducts a wagering pool or lottery, or is required to register and took wagers for another person without reporting that person's name and address. The return is monthly: it is due "by the last day of the month following the month" for which wagers are being reported, and the instructions say to file every month whether or not there are taxable wagers, writing "None" on line 6 when there is no tax. The IRS will not send a reminder.

The form follows the statute line by line:

1. Line 1 is the gross amount of wagers accepted during the month, excluding laid-off wagers, including any fee incident to placing the wager.
2. Line 2 is laid-off wagers accepted during the month.
3. Line 4a multiplies the authorized wagers by 0.0025.
4. Line 4b multiplies all other wagers by 0.02.
5. Line 5 is credits, for example for an overpayment or for tax on a wager the operator laid off with another taxpayer, and no credit is allowed without supporting evidence.
6. Line 6 is the balance due.

The overpayment credit has a condition that shows how the statute thinks about who bears the tax. The instructions allow it only with a statement that the operator did not collect the tax from the bettor (as a separate charge or otherwise), has repaid it to the bettor, or has the bettor's written consent.

Form 11-C, Occupational Tax and Registration Return for Wagering. Separately from the per-wager tax, 26 U.S.C. § 4411 imposes a "special tax of $500 per year" on each person liable for the § 4401 tax and on each person receiving wagers on their behalf. Section 4411(b) reduces it to $50 for a person whose liability is determined only under the 0.25 percent rate in § 4401(a)(1), and for anyone receiving wagers only for such persons. In plain terms: $50 a year for a state-authorized operation, $500 for an unauthorized one.

The Form 11-C instructions add the timing. The first return is filed before wagers are accepted, and a renewal is due by July 1 each year, because the tax period runs from July 1 to June 30. An operator that starts after July is charged a prorated amount from a table in the instructions; one that starts in January, for example, owes $25 under the $50 rate or $250 under the $500 rate. The form also registers principals and their agents, and a new agent must be reported within 10 days of being engaged.

Which bets are exempt, and does the bettor ever see the tax?

26 U.S.C. § 4402 lists three exemptions:

• wagers placed with, or in a pool run by, a parimutuel wagering enterprise licensed under state law;
• wagers placed in a coin-operated device;
• wagers in a sweepstakes, wagering pool or lottery conducted by a state agency under state law, as long as the wager is placed with that agency or its authorized employees or agents.

The Form 730 and Form 11-C instructions add two more items that fall outside the definition of a taxable lottery under § 4421: games in which the people wagering are present when the wagers are placed, winners are determined and prizes are paid, and certain drawings by tax-exempt organizations. The Form 730 instructions say that card games, roulette, dice games, bingo, keno and gambling wheels usually fall within the "present" exception, and they give slot machines as an example of a coin-operated device.

Put together, the federal wagering excise tax is in practice a tax on bookmaking and on for-profit pools and lotteries. A table-game bet, a slot spin, a state lottery ticket and a parimutuel horse-racing ticket are outside it. A sports bet placed with a sportsbook is inside it.

Does the bettor see it? The statute puts the liability on the operator. Section 4401(b) allows an operator to collect the tax as a separate charge, and if it does so and can prove it, the charge is not itself taxed. If a ticket shows only the stake, the price and the payout, with no separate excise line, the 25 cents per $100 is being paid out of the book's margin. The bettor pays it only indirectly, through prices that already carry that margin.

Does it affect the bettor's own taxes? No. The excise tax under § 4401 is separate from the income tax on gambling winnings. A winning bettor's income tax treatment is governed by the income tax rules and information-reporting forms such as Form W-2G, not by Form 730.

The statute's text is short enough to read in full: 26 U.S.C. § 4401, with the exemptions in 26 U.S.C. § 4402 and the occupational tax in 26 U.S.C. § 4411.
