Free calculator · Tax year 2026
Do you owe tax on gambling winnings without a W-2G?
All gambling winnings are taxable income, whether or not you receive a Form W-2G. The form is a REPORTING threshold, not a taxability threshold — a $50 sports-bet win and a $50,000 jackpot are both income, and only one of them generates paperwork.
This is tax owed, not your balance due. If the payer already withheld tax from a payout, that is a prepayment against this amount — this calculator does not model withholding.

When does a payer issue a W-2G?
These thresholds decide when the payer must send a form. They do not decide what is taxable — the income above is reportable either way.
- Bingo or slot machines
- $1,200 or more (not reduced by the wager)
- Keno
- $1,500 or more, reduced by the wager
- Poker tournaments
- $5,000 or more, reduced by the buy-in
- Other wagering (incl. sports betting)
- $600 or more AND at least 300× the wager

Common questions
- Do I have to report gambling winnings if I did not get a W-2G?
- Yes. All gambling winnings are taxable income under §61 regardless of whether a Form W-2G was issued. The form is a payer reporting obligation triggered by dollar thresholds — it does not define what is taxable.
- How much do I have to win before it is taxable?
- There is no minimum. Every dollar of winnings is income. The thresholds people have in mind ($1,200 slots, $600 with 300× odds, and so on) decide when the payer must send you and the IRS a form, not when the income becomes taxable.
- Tax was withheld from my payout — am I square with the IRS?
- Not necessarily. Withholding is a prepayment, not a final tax. Whether it covers what you owe depends on your bracket and your other income. This calculator shows the tax the winnings ADD; it does not model amounts already withheld.
- Can I just report my net winnings for the year?
- No. Winnings are reported in full as income, and losses are a separate itemized deduction capped at 90% of losses from 2026 — which is why a break-even year can still produce tax.
