$10,000 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
- Colorado tax
- Colorado taxes sports betting winnings as ordinary income at a flat 4.4%.[1]
- Federal tax form
- Sports betting 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 sports betting winnings of more than $5,000, but only when the win is also at least 300 times the wager.[2]
- Colorado withholding
- Colorado withholds 4% whenever federal tax is withheld.[5]
- Gambling losses
- Losses reduce Colorado tax only through your federal itemized deductions. Colorado has no separate gambling-loss deduction.[6]
- Visitors
- Colorado taxes nonresidents on sports betting winnings won there, so visitors may need to file a nonresident return.[7]
- Where to play
- Sports betting in Colorado: legal online and in person. Winnings from a bet placed in another state are taxable here all the same.[8]
