Important Identity Verification Information
Please note that in the best interest of all taxpayers, the Colorado Department of Revenue implements measures to detect and prevent identity theft related refund fraud. Please be aware that these measures, meant to ensure state tax dollars are going to the right person, could delay individual income tax refunds. If you have received a letter requesting that you verify your identity and/or tax return details, it is important that you promptly respond to the letter.
Check Refund Status Online
You can check the status of your refund on Revenue Online. There is no need to login. Simply choose the option "Tax Refund for Individuals" in the box labeled "Where's my Refund?". Then, enter your SSN or ITIN and the refund amount you claimed on your current year income tax return. If you do not know the refund amount you claimed, you may either use a Letter ID number from a recent income tax correspondence from the Department.
You will receive the Letter ID within 7-10 business days. After we have received and processed your return, we will provide you with an updated status as the refund moves through our system. It may take a few days for an updated status to appear. Please check back often to verify where your return/refund may be in our process.
The information in Revenue Online is the same information available to our Call Center representatives. You can get the information without waiting on hold.
Frequently Asked Questions
I can't check the status. What do I do?
Please verify the refund amount you have entered and verify that you are using the primary SSN for the return/refund. You may want to try using a Letter ID instead of the refund amount.
You have not updated the status of my refund in a while. When will I receive it?
Each return processes through multiple steps. We recommend you file electronically and include all documentation to ensure we can process your return/refund as quickly as possible. Please check back on the status daily. If we require additional information, we will contact you through U.S. Postal Service mail.
I received a "Validation Key" letter. Will that delay my refund?
In the best interest of all our taxpayers, the Colorado Department of Revenue implements measures to detect and prevent identity theft-related refund fraud. The Department has a "Validation Key" process where information will be requested to be entered on Revenue Online to validate their Colorado refund. Please be aware that if you do not respond to the validation key letter in a timely manner your refund will be delayed. Visit the Identity Verification web page for more information.
