Do You Pay Taxes on Sportsbook Bonus Bet Winnings? Yes — Here's How
Yes, all sports betting winnings are taxable federal income — including any cash profit you earn from a winning bonus bet. The IRS makes no exception for how the wager was funded.
What Makes Bonus Bet Winnings Taxable?
When you place a bonus bet and win, the sportsbook pays out only the profit, not the stake. That profit is real cash in your account. Per guidance covered by the Financial Planning Association's study on sports betting taxation, all gambling winnings must be reported on Form 1040, Line 8 ("Other Income") — even if the sportsbook sends you no tax form at all.
Example: a $25 bonus bet at +100 odds wins. The sportsbook pays $25 in real cash profit. That $25 is taxable income for the year you received it. The bonus bet stake itself was never your withdrawable money, so only the profit counts — but that profit absolutely does count.
Which Tax Forms Will You See?
Two forms come into play depending on how much you win.
- Form W-2G — issued when a single wager produces winnings of $600 or more and at least 300× the bet amount.
- Form 1099-MISC — issued when your net gambling winnings for the year exceed $600.
If neither threshold is crossed, the sportsbook may send nothing. You still owe the tax. Keep your own records.
How Are Winnings Actually Taxed?
Gambling winnings are taxed at your marginal federal income tax rate. If your total income sits around $60,000 and you add $4,000 in betting profits, that $4,000 falls in the 22% bracket — roughly $880 in federal tax owed on that amount alone.
State tax rates vary. New York, Rhode Island, and New Hampshire apply among the highest state-level rates on gambling income.
Can You Deduct Gambling Losses?
Yes, but only if you itemize deductions on your federal return — and only up to the total amount you won. Losses cannot offset wages or any other income.
Example: you won $1,500 and lost $1,000 during the year. You may deduct up to $1,000. Taxable gambling income = $500.
Track every session. A spreadsheet with dates, sportsbook names, bet amounts, and outcomes is your best protection if the IRS asks questions.

Tax Treatment by Wager and Form Type — Quick Reference
| Situation | Tax Form | Reportable? |
|---|---|---|
| Win $25 profit from a $25 bonus bet | Likely none (below $600 threshold) | Yes — still report on Form 1040 |
| Single bet returns $600+ and is 300× the stake | Form W-2G from sportsbook | Yes |
| Net winnings exceed $600 for the year | Form 1099-MISC from sportsbook | Yes |
Red Flags and Common Mistakes
Many bettors assume that because a bonus bet stake is non-withdrawable, the whole transaction is somehow off the books. It is not. The cash profit that hits your real-money balance is income the moment you receive it.
Another mistake: waiting for a form before filing. If the sportsbook doesn't hit the reporting threshold, no form arrives — but the IRS still expects you to report any winnings. See the rg.org deposit bonus overview for context on how regulated US sportsbooks handle bonus structures and disclosures.
Note that some states ban credit card deposits entirely, which can affect how you fund the account that generates those winnings in the first place. Our breakdown of credit card deposit bans at sportsbooks by state covers Iowa, Tennessee, Massachusetts, and New York specifically.
