The Colorado Department of Revenue routinely takes precautionary measures to ensure taxpayer refunds are not diverted to identity thieves. The Department reviews all income tax refunds because it is operating in the public trust with revenue dollars collected and refunded. The Department has several refund factors it reviews, including factors for refund fraud related to identity theft. Our objective is to protect taxpayer information, as well as state revenue, and ensure taxpayers receive the Colorado state income tax refund to which they are entitled. However, these measures may delay any expected refund.
If you receive a letter from us, please respond quickly so we may review your information and get your refund to you as soon as possible. Refunds will be delayed until we get the requested information and we’re able to review. If you do not respond, you return will not be processed. See a Sample Letter to verify the letter you received is from us.

Colorado income tax refunds that were requested to be direct deposited may be converted to a paper check. Sending a paper check to the taxpayer’s mailing address is intended to prevent criminals from easily diverting fraudulent refund to their own prepaid, reloadable cards or debit cards. Receiving a paper check does not mean a taxpayer’s identity has been compromised. It is a safeguard measure implemented by the Department. If you receive a letter and paper income tax refund check from the Colorado Department of Revenue this year and you have not filed your tax return yet or you are not expecting a refund, you may call the fraud hotline number included in the letter. The Department appreciates taxpayers’ patience and understanding while it takes necessary steps to protect Colorado income tax refunds.
