Are Sports Betting Winnings Taxable?

Yes. The IRS treats gambling winnings — including sports betting winnings — as ordinary income. They are taxable at your marginal income tax rate, regardless of whether the sportsbook issues a W-2G form.

This includes:

The W-2G Form — When Sportsbooks Report to the IRS

For sports betting, the $600 threshold means most individual matched bets don't trigger automatic reporting — the winnings are usually below this on any single transaction.

How Promo Grinding Winnings Are Typically Taxed

For most recreational promo grinders (not running it as a business), gambling winnings are reported as "Other Income" on Schedule 1 of Form 1040. Key points:

After-tax net profit$3,276
Effective after-tax hourly (10 hrs/week)~$63/hr
