You can check the status of your Colorado state tax refund online using the Colorado Department of Revenue's official tool called "Where's My Refund?" available at https://tax.colorado.gov/refund or https://www.colorado.gov/revenueonline. No login is required; you just need to select your account type, ID type, enter your Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN), and provide either your refund amount or a PIN/Letter ID from a tax correspondence
. Typical refund processing times are:
- E-filed returns: about 3-5 weeks
- Paper-filed returns: up to 3 months
Paper check refunds usually take 7-10 business days after mailing to arrive, but can sometimes take up to 45 days. If you haven't received your refund check after 45 days, you can call the Colorado Tax Information Call Center at 303-238-7378 to request a refund reissue form
. Delays can occur due to:
- Need for additional verification or information
- Math errors or incomplete returns
- Use of multiple form types
- Fraud protection processes that may delay refunds up to 60 days beyond normal timeframes
If you receive a "Validation Key" letter from the Colorado Department of Revenue, responding promptly is necessary to avoid refund delays
. For federal refund status, use the IRS "Where's My Refund?" tool separately
. In summary, to find your Colorado refund status:
- Visit the Colorado Department of Revenue refund status page
- Enter your information as prompted
- Check back often as status updates may take a few days to appear
If your refund is delayed or missing, contact the Colorado Tax Information Line at 303-238-7378 for assistance
