Sportsbook Tax Rules Every US Bettor Should Understand
New York's 51% revenue tax and Illinois's per-wager levy affect bonus generosity and odds. Here's how state tax rules shape your betting options.
State tax rates are not fine print — they directly affect what sportsbooks can afford to offer you. New York taxes mobile sports wagering gross revenue at 51% and does not allow promotional gaming credits as a deduction before that tax is applied. That's why bonuses in New York are thinner than nearly anywhere else. Illinois took a different approach: since July 1, 2025, it imposes a 25-cent per-wager tax on the first 20 million wagers annually, rising to 50 cents per wager beyond that threshold, per the Illinois Gaming Board. Both structures cost operators real money. That cost gets passed to bettors through tighter odds and smaller promos.
US legal sports betting handle reached nearly $150 billion in 2024. With that kind of volume, state-level gross gaming revenue and hold-percentage data in regulatory filings matter. Operators don't absorb tax differences quietly — they adjust.

How do state tax structures affect the bonuses I actually get?
New York's 51% revenue tax and Illinois's per-wager tax structure mean sportsbook promotional spending — and therefore bonus generosity — varies materially state by state. Operators in high-tax states have less margin to fund large welcome offers.

Which states hit sportsbooks hardest on taxes?
| State | Tax Structure | Promo Deduction Allowed? | Regulator |
|---|---|---|---|
| New York | 51% of mobile gross gaming revenue | No | New York State Gaming Commission |
| Illinois | 25¢/wager (first 20M); 50¢/wager above 20M (effective July 1, 2025) | Per-wager structure (not GGR-based) | Illinois Gaming Board |
| New Jersey | Regulated by NJ Division of Gaming Enforcement | Not specified in available data | NJ Division of Gaming Enforcement |
Does the tax structure change the odds sportsbooks post?
Yes, indirectly. A book operating on razor-thin margins after a 51% tax hit has less room to offer reduced juice or competitive lines. That's one reason shopping for the best number matters more in high-tax states. The standard hold at -110 on both sides is roughly 4.77%. Some books post -108, cutting that margin — but not all can afford to in states like New York. See High-Hold Bets US Sportsbooks Don't Want You to Know About for the specific market types where operators quietly pad their edge the most.
Does any major sportsbook handle high-tax states better than others?
FanDuel is one of the two largest US operators by handle and operates across most legal states, including New York. How it prices lines and structures promos in high-tax markets is worth reviewing before you deposit. Read the FanDuel Sportsbook Review: Is It the Best US Betting App? for a full breakdown. State tax rules are one input; odds quality, withdrawal speed, and app reliability are others.
