$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
- New Mexico tax
- New Mexico taxes horse racing winnings as ordinary income at graduated rates from 1.5% to 5.9%.[1]
- 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]
- New Mexico withholding
- New Mexico withholds 6% on horse racing winnings of $2,000 or more.[5]
- Gambling losses
- Gambling losses count only through your federal itemized deductions, which New Mexico copies from your Form 1040, so the 90% limit carries over.[6] How the federal 90% loss rule works
- Visitors
- New Mexico taxes nonresidents on horse racing winnings won there, so visitors may need to file a nonresident return.[7]

Records to keep for horse racing winnings
Pari-mutuel winnings are your payout minus the bet. A W-2G and withholding both need the win to be at least 300 times the bet, which exotic bets like trifectas often clear.
Losses only count if you can prove them. For horse racing winnings, the IRS suggests keeping:[8]
- The races you bet on and the amount of each wager
- What you collected on winning tickets and lost on losing tickets
- Unredeemed tickets and payment records from the track
All of this goes alongside the diary the IRS expects for every kind of gambling: keeping gambling records the IRS will accept.
