How to claim a prize
How you claim depends on the amount:
$599 or less: collect from many retailers, or mail your signed ticket to the Colorado Lottery in Pueblo.
$600 or more: bring your signed ticket and photo ID to one of the four Lottery claim centers, start a claim online, or mail it in.
Sign the back of your ticket, and note that all prizes must be claimed within 180 days of the drawing. Jackpot winners have 60 days after validating the ticket to switch from the annuity to the cash option.
Taxes on winnings
Colorado taxes lottery winnings. For prizes of $5,001 or more, the Lottery withholds 28% up front (24% federal plus 4% Colorado state). For nonresidents or foreign nationals, the withholding is 34% (30% federal plus 4% state).
The final federal bill can be higher than the amount withheld, depending on your total income, so it is worth speaking to a tax professional for a large win.
Can you stay anonymous?
Not fully. Under the Colorado Open Records Act, the Lottery is required to release a winner’s first name, last initial, hometown, the amount won and the game played. That information is posted online and provided to the media on request.
Some elements are optional: having your photo taken and taking part in publicity are up to you. But your basic details are public record, so Colorado does not offer complete anonymity. Winners who want more privacy sometimes seek legal advice about claiming through a trust or other entity.
