Refund

On May 23, 2022, Gov. Jared Polis signed a new law (Senate Bill 22-233) to give Coloradans a tax rebate of $750 for individual filers and $1,500 for joint filers this summer. If you've already filed your Colorado state income tax return, you're all set! You will receive your Colorado Cash Back check in the mail soon. For more information contact the call center at 303-951-4996 or visit Colorado Cash Back.

The U.S. Postal Service will forward paper check tax refunds when a forwarding mailing address has been submitted. However, if you did not submit a forwarding address with USPS, a paper check must be reissued with your correct address. You must call our Tax Information Call Center at 303-238-7378 to start the process.

• Lost: You can request that the original refund be voided and a new refund be issued. Follow the Reissue Process below.
• Missing: Did you use the correct mailing address when you filed the return? Check the status of your refund and your address by visiting Revenue Online.
• Damaged/Destroyed: You can request that the original refund be voided and a new refund be issued. Follow the Reissue Process below.

Reissue Process for Missing, Lost or Destroyed Refunds

You can start the refund check reissue process by signing a refund reissue letter. Request the letter through 303-238-SERV (7378)

In the best interest of all our taxpayers, the Colorado Department of Revenue implements measures to detect and prevent identity theft-related refund fraud. Fraud detection, along with verification that claims made on an individual income tax return are valid and the documentation is submitted with the returns, are part of the process of ensuring the return is correct and complete and that taxpayers receive the refund amount to which they are entitled. Please be aware that these measures, meant to ensure state tax dollars are going to the right person, could delay individual income tax refunds up to 60 days beyond the time frames of prior years.

To verify your identity, the Department may request the following: 

• Validation Key: the Department has a "Validation Key" process where information will be requested to be entered on Revenue Online to validate their Colorado refund. Visit the Identity Verification web page for more information. 
• Copy of Driver License or ID
• Copy of a document containing your name and address
• Copy of W-2(s) and/or 1099(s) claiming Colorado tax withholding
• Refund Amount

Revenue Online is the fastest, safest and most secure means to upload requested documents.
