$8,000 is at or above the $2,000 reporting threshold, so the payer files a W-2G with the IRS and gives you a copy.
The payer holds back 24% of winnings over $5,000 and sends it to the IRS. It's a prepayment, not the final tax.
Winnings are ordinary income stacked on your other $60,000. Your top dollar lands in the 22% bracket.

The rules
- Idaho tax
- Idaho taxes horse racing winnings as ordinary income at graduated rates from 0% to 5.3%.[1]Unverified
- Federal tax form
- Horse racing (pari-mutuel) winnings are reported on a W-2G when they are $2,000 or more (after subtracting the wager) and at least 300 times the wager. The threshold was $600 before 2026.[2]
- Federal withholding
- 24% is withheld from pari-mutuel winnings of more than $5,000, but only when the win is also at least 300 times the wager.[2]
- Idaho withholding
- No Idaho withholding requirement for horse racing winnings. Tax is due when you file.[5]
- Gambling losses
- You can deduct gambling losses only if you itemize: Form 40 uses your federal Schedule A deductions, with federal limits, so the 90% limit applies.[6]
- Visitors
- Idaho taxes nonresidents on horse racing winnings won there, so visitors may need to file a nonresident return.[7]
