How to check your Colorado state tax refund
Colorado's Department of Revenue runs a tool called Where's My Refund that shows you the status of your state income tax refund. You enter your Social Security number, filing status, and the exact refund amount from your return, and the system tells you whether your refund has been processed, is in the mail, or is still being reviewed.
The tool is available on the Colorado Department of Revenue website at tax.colorado.gov. Look for the "Where's My Refund" link on the homepage — it is usually in the main navigation or under a "Refunds" section. You do not need to log into an account; you can check your status without creating a login.
The system updates once per day, typically overnight. If you filed electronically, your refund usually processes faster than a paper return. Colorado typically issues refunds within 21 days of receiving an electronic return, though complex returns or those requiring verification can take longer.

What information you need to check your refund status
Before you use Where's My Refund, gather three pieces of information from your tax return: your Social Security number, your filing status (single, married filing jointly, married filing separately, or head of household), and the exact refund amount you claimed on your return.
The refund amount must match exactly what appears on your return. If you claimed a $1,250 refund, enter $1,250 — not $1,200 or $1,300. The system will not find your return if the amount is off, even by a few dollars. If you are unsure of the exact amount, check your filed return or the confirmation email you received if you filed electronically.
You do not need your filing date, your return confirmation number, or any other information. The three pieces above are sufficient to search the system.
How long Colorado takes to process refunds
Colorado's standard processing time is 21 days from the date the Department of Revenue receives your return. This timeline applies to electronically filed returns that are complete and do not require additional review. Paper returns typically take longer — usually four to six weeks from receipt.
If you chose direct deposit, your refund reaches your bank account within one to three business days after the Department of Revenue releases it. If you requested a check by mail, allow an additional five to seven business days for postal delivery, depending on your location.
Returns that trigger additional review — for example, if you claimed a large credit, reported self-employment income, or made an error on your return — may take longer than 21 days. The Where's My Refund tool will show a status message if your return is under review.
What to do if your refund is delayed
If your refund has not arrived within 21 days of filing electronically, or within six weeks of mailing a paper return, check Where's My Refund again to see if the status has changed. If the tool shows your refund was issued but you have not received it, the delay is usually in the mail or banking system, not with the Department of Revenue.
If Where's My Refund shows your return is still being processed after six weeks, or if the tool shows an error message, contact the Colorado Department of Revenue directly. Call their refund line at 303-238-REFUND (7338) during business hours, Monday through Friday. Have your Social Security number and return information ready when you call.
If you filed by mail and have not received a confirmation that the Department of Revenue received your return, consider filing electronically instead. You can file an amended return (Form 104-X) electronically even if you filed on paper originally, which usually speeds up processing.
Reasons your Colorado refund might be held or delayed
The Department of Revenue may hold your refund if your return contains errors, if you claimed credits that require verification, or if there is a discrepancy between your state and federal return. Common triggers include mismatched income information, unreported federal credits, or a change in your filing status from the previous year.
If you owe Colorado back taxes, child support, or other state debts, the Department of Revenue may offset your refund to pay those obligations. This is called a refund offset. If this happens, you will receive a notice in the mail explaining what your refund was applied to and how much was taken.
Identity theft or fraud flags can also delay processing. If the Department of Revenue suspects your return may be fraudulent, they will hold it for manual review. This is rare but can add several weeks to processing time. You will be contacted if this occurs.
Direct deposit versus check refunds
Choosing direct deposit is the fastest way to receive your Colorado refund. Direct deposit refunds arrive within one to three business days after the Department of Revenue processes your return. You need your bank account number and routing number to set up direct deposit when you file.
If you request a check instead, the Department of Revenue mails it to the address on your return. Delivery typically takes five to seven business days, but can be longer depending on postal service delays and your location. Some checks take up to two weeks to arrive.
If you filed electronically but did not set up direct deposit, you can still add your bank account information through Where's My Refund in some cases, though this depends on the processing stage of your return. Call the refund line at 303-238-REFUND (7338) to ask if your return can be redirected to direct deposit.
What to do if you never received your refund check
If Where's My Refund shows your refund was issued as a check but you have not received it after two weeks, the check may have been lost in the mail or sent to an old address. Contact the Department of Revenue at 303-238-REFUND (7338) to request a replacement check or to have your refund reissued by direct deposit instead.
Have your Social Security number, current mailing address, and the refund amount ready. The Department of Revenue can issue a replacement check, though this may take an additional two to three weeks. Requesting direct deposit reissuance is usually faster.
If you moved after filing your return, update your address with the Department of Revenue before calling. You can update your address through the Colorado Department of Revenue website or by mail using Form 104-ADR.
Frequently Asked Questions
Can I check my refund status if I filed a joint return?
Yes. Use either spouse's Social Security number, the filing status (married filing jointly), and the refund amount shown on the return. The system will find the return regardless of whose number you enter, as long as the other information matches.
What if I filed an amended return — does that change my refund timeline?
Yes. An amended return (Form 104-X) restarts the processing clock. Colorado typically takes an additional 21 days to process an amended return after it is received. If you amended your return to increase your refund, you will receive the additional amount once the amended return is processed.
Does Where's My Refund work for federal and state refunds?
No. Colorado's Where's My Refund tool shows only your state refund status. To check your federal refund, use the IRS tool "Where's My Refund" on the IRS website at irs.gov. The two systems are separate.
What if the refund amount I enter does not match what I think I claimed?
Check your filed return or your filing confirmation email. If you filed electronically, your tax software should have sent you a confirmation email with the exact refund amount. If you filed on paper, look at the bottom of your Form 104 (Colorado Individual Income Tax Return) — the refund amount is listed there. Enter that exact number into Where's My Refund.
Can I cancel my refund or change how I receive it after I file?
Once your return is filed and processed, you cannot cancel the refund. However, if your refund has not yet been issued, you may be able to change the delivery method from check to direct deposit. Call 303-238-REFUND (7338) to ask if this is possible for your return.
