Form W-2G
Yes

$5,000 is at or above the $2,000 reporting threshold, so the payer files a W-2G with the IRS and gives you a copy.

Federal withholding at payout
$0

Casino and slots winnings aren't subject to regular federal withholding, whatever the amount. Tax is still owed when you file. If you don't give the payer your Social Security number, 24% backup withholding applies.

Federal tax on the winnings
$600

Winnings are ordinary income stacked on your other $60,000. Your top dollar lands in the 12% bracket.

State tax
$220

Colorado taxes gambling winnings as ordinary income.

Still to pay when you file
$820

Tax owed ($820) minus what was withheld ($0). Set this aside. A large balance can also mean an underpayment penalty unless you make an estimated payment.

You keep
$4,180

$5,000 minus $820 in federal and state tax: an effective rate of 16.4%.

An estimate for 2026, not tax advice. It treats this win as your only gambling income for the year and leaves out local income taxes. Nothing you enter leaves your browser.
