How to check the status of your Colorado state tax refund
Colorado's Department of Revenue runs a refund tracker called Where's My Refund? that shows you the status of your state income tax refund in real time. You can access it on the Colorado Department of Revenue website without logging in — you only need your Social Security number and the amount of the refund you expect.
The tracker updates once per day, usually overnight. If you filed electronically, your refund typically processes within 21 days. If you filed by paper, allow 4 to 6 weeks. The tracker will tell you whether your return is still being processed, has been approved, or has been sent to your bank or mailed as a check.
If the tracker shows your refund was sent but you haven't received it, the next step depends on the delivery method. Direct deposits usually arrive within 1 to 3 business days after the tracker shows approval. Mailed checks take 7 to 10 business days from the approval date, depending on postal service delays in your area.

- Electronic returns typically show a refund within 21 days; paper returns take 4 to 6 weeks before processing begins.

What information you need to use the tracker
To look up your refund status, have your Social Security number and the refund amount ready. The refund amount is the number you see on line 21 of your Colorado Form 104 (the state income tax return form), or the amount you entered when you filed electronically. If you're not sure of the exact amount, entering it within $1 or $2 usually works — the system is designed to be flexible.
You do not need your PIN, password, or any login credentials. The tracker is public-facing and intentionally simple so you can check status without barriers. If you filed jointly with a spouse, either spouse's Social Security number will work.
Timeline: when to expect your refund
The timeline depends on how you filed and how you requested the refund.
| Filing Method | Processing Time | Delivery Time After Approval |
|---|---|---|
| Electronic filing, direct deposit | Up to 21 days | 1 to 3 business days |
| Electronic filing, mailed check | Up to 21 days | 7 to 10 business days |
| Paper return, direct deposit | 4 to 6 weeks | 1 to 3 business days |
| Paper return, mailed check | 4 to 6 weeks | 7 to 10 business days |
These are typical timelines, not guarantees. Returns with errors, missing information, or that trigger fraud reviews take longer — sometimes 60 to 90 days. The Where's My Refund? tracker will show a message if your return needs attention.
What to do if your refund is delayed
If the tracker shows your refund was sent but you haven't received it after the expected timeframe, first verify the delivery method. Log into the tracker again and confirm whether it was sent as a direct deposit or a check. If it was direct deposit, wait one additional business day — sometimes banks take longer than expected to post the deposit.
If it was mailed as a check and more than 10 business days have passed since approval, contact the Colorado Department of Revenue at 303-238-REFUND (303-238-7386). Have your Social Security number, filing status, and the refund amount ready. The department can confirm whether the check was mailed, issue a replacement check, or in some cases arrange a direct deposit instead.
Checks can be lost in the mail, especially during high-volume periods in spring. The department keeps records of all checks issued and can reissue yours if it's been more than 30 days since the approval date shown in the tracker.
If your return was rejected or needs corrections
If the tracker shows your return was rejected or is on hold, the message will usually explain why. Common reasons include a mismatched Social Security number, a missing signature (on paper returns), or income reported on a W-2 or 1099 that doesn't match what you entered.
If you filed electronically and your return was rejected, you can file an amended return (Form 104-X) or file a new return with the corrections. If you filed by paper and it was rejected, the Department of Revenue will mail you a notice explaining the issue. You'll have time to respond — do not ignore the notice.
If you're unsure what the rejection means, call 303-238-REFUND. The department's phone lines are busiest in March and April, so calling in May or later usually means shorter wait times.
Direct deposit versus mailed check
When you filed your return, you chose how to receive your refund. Direct deposit is faster — it arrives 1 to 3 business days after approval — and there's no risk of the check being lost. To use direct deposit, you need to provide your bank account number and routing number on your return.
If you requested a mailed check, the Department of Revenue prints and mails it from their office in Denver. Delivery depends on where you live in Colorado and how busy the postal service is. Urban areas usually see checks arrive within 7 to 10 business days; rural areas may take longer.
You cannot change your delivery method after you file. If you chose a check and want your refund faster, you can't switch to direct deposit for that year's refund. For future years, choose direct deposit when you file.
What happens if you moved or changed your address
If you moved after filing but before your refund arrived, the check may be sent to your old address. The post office will not automatically forward tax refund checks — they're treated as official government mail.
If this happens, contact the Colorado Department of Revenue as soon as you realize the check went to the wrong address. Provide your old address, new address, and the refund amount. The department can issue a replacement check to your current address or arrange a direct deposit if you provide bank details.
If you filed electronically and used direct deposit, address changes don't affect your refund — it goes to your bank account, not a mailing address.
Frequently Asked Questions
Can I check my refund status without my Social Security number?
No. The tracker requires your Social Security number and the refund amount to pull up your status. This is a security measure to prevent someone else from looking up your information. If you don't remember the refund amount, check your filed return or the confirmation email you received when you filed electronically.
Why does the tracker say my refund is still processing after 21 days?
Electronic returns usually process within 21 days, but some take longer if they're flagged for review, contain errors, or if the department is processing a high volume of returns. The tracker will show a message if your return needs attention. If it just says "processing" after 30 days, call 303-238-REFUND to ask whether your return is in queue or held for review.
What if I filed a paper return and never got a confirmation?
Paper returns don't generate email confirmations. The Department of Revenue processes them in the order received, which can take 4 to 6 weeks. You can check status using the Where's My Refund? tracker with your Social Security number and expected refund amount. If the tracker shows no record of your return after 8 weeks, call the department to confirm they received it.
Can I get my refund as a direct deposit if I originally requested a check?
No. Once you file, you cannot change the delivery method for that year's refund. If your check is lost or delayed beyond 30 days, the Department of Revenue can reissue it as a check or, in some cases, arrange a direct deposit if you provide banking information. For future years, choose direct deposit when you file to speed up delivery.
Is there a phone number I can call if the website is down?
Yes. Call the Colorado Department of Revenue at 303-238-REFUND (303-238-7386). The phone line is available Monday through Friday, 8 a.m. to 4:30 p.m. Mountain Time. Wait times are shortest in early summer and fall; expect longer holds in March, April, and May.
