Yes, spread bet winnings are taxable. All US gambling winnings — including sports betting — are federally taxable as ordinary income under IRS rules, no matter how small the amount.
What does the IRS say about gambling winnings?
The IRS treats every dollar won from a spread bet as ordinary income. That means it gets added to your gross income for the year and taxed at your marginal rate. There is no special lower rate for gambling. Per IRS Topic No. 419 — Gambling Income and Losses, this applies regardless of whether the sportsbook sends you any paperwork.
When does a sportsbook issue a W-2G?
Licensed sportsbooks are required to issue a W-2G form when net winnings from a single bet are $600 or more and at least 300 times the original wager. That threshold catches many sports betting wins. If the W-2G threshold is met and you have not provided a valid taxpayer identification number, the book withholds 24% of the payout automatically. Even if no W-2G arrives, you are still legally required to report the income.
Can you deduct gambling losses against spread bet winnings?
Yes, but only if you itemize deductions on your federal return. Losses can offset winnings dollar-for-dollar — they cannot exceed your reported winnings, and they cannot be carried forward to a future tax year. Keep a running log of every wager: date, sport, amount wagered, and outcome. Sportsbook account history reports are useful supporting documents.
What about state income taxes?
States with legal sports betting generally tax gambling winnings as ordinary income at the state rate. The rate varies. If you bet in multiple states, you may have reporting obligations in more than one. Check with a tax professional if you are unsure.

Practical steps for spread bettors at tax time
- Download your full betting history from your sportsbook account before year-end.
- Track wins and losses separately — the IRS does not allow you to report a net figure without itemizing.
- Check whether your state requires a separate gambling income schedule.
- If you received a W-2G, confirm the withholding amount matches your records before filing.
