Check your refund status through the Colorado Department of Revenue website

The Colorado Department of Revenue operates a refund tracker where you can see the status of your state tax return. Go to tax.colorado.gov and look for the "Where's My Refund?" tool. You'll need your Social Security number, filing status (single, married filing jointly, etc.), and the exact refund amount from your return.

The tracker updates once per week, usually on Wednesdays. If you filed electronically, your return typically processes within 21 days. If you mailed a paper return, allow 4 to 6 weeks before the tracker will show any activity. The tool will tell you whether your return is still being processed, approved, or has been sent to your bank.

If the tracker shows your refund was approved but you haven't received it, check your bank account for a pending deposit. Direct deposits can take an additional 3 to 5 business days to appear after the state releases the money. If you chose a paper check, allow 7 to 10 business days for mail delivery after the state issues it.

Key Takeaways

  • The Colorado Department of Revenue's "Where's My Refund?" tool at tax.colorado.gov shows your return status and requires your Social Security number and refund amount.
  • Electronic returns typically process within 21 days; paper returns take 4 to 6 weeks before appearing in the tracker.
  • The tracker updates weekly on Wednesdays, so checking more frequently won't show new information sooner.
  • Direct deposits take 3 to 5 additional business days after approval; paper checks take 7 to 10 business days for mail delivery.
  • If your return shows errors or is held for review, the Department of Revenue will contact you by mail with next steps.

What delays commonly hold up Colorado refunds

The most common reason a return sits in processing is a mismatch between what you reported and what the IRS reported to Colorado. This happens when your W-2 or 1099 information doesn't match your return, or when you claimed a dependent the IRS doesn't recognize. The Department of Revenue will send you a letter explaining the issue and what documents to send back.

A second frequent delay occurs when you claim the Colorado child tax credit or earned income tax credit. These credits require verification, especially if your income changed significantly or you're claiming them for the first time. The state may request recent pay stubs or a letter from your employer confirming your income.

Returns filed late in the tax season (after mid-April) often process more slowly because the Department of Revenue receives a higher volume. If you filed in May or June, your return may not appear in the tracker for several weeks even if there are no errors.

What to do if your refund hasn't arrived after the expected timeframe

If your return shows as approved in the tracker but your money hasn't arrived within the stated timeframe, contact the Colorado Department of Revenue directly. Call their taxpayer service line at 303-238-TAX (8299). Have your Social Security number, filing status, and refund amount ready. They can confirm whether the payment was sent and, if so, whether it went to the correct bank account.

If you provided a bank account number on your return and the refund was sent but never arrived, your bank may have rejected the deposit. This sometimes happens if the account was closed or if the routing number was entered incorrectly. The Department of Revenue can reissue your refund as a check, though this adds another 7 to 10 business days.

Keep any letters the Department of Revenue sends you. If they're requesting documents or information, respond within the timeframe stated in the letter. Ignoring a request can result in your refund being held indefinitely or denied.

How to update your bank account information if it changed

If you filed your return with one bank account but that account is now closed or you've switched banks, you cannot change the account number through the tracker. Instead, contact the Department of Revenue by phone at 303-238-TAXI (8299) and explain the situation. They can issue a check to your mailing address instead, or in some cases reissue the direct deposit to a new account if you provide written authorization.

The process of reissuing a refund takes an additional 2 to 3 weeks. If you're in a time-sensitive situation, ask whether the Department of Revenue can issue a check that you can pick up in person at a local office, though this option is not always available.

Understanding the difference between state and federal refund timing

Your Colorado state refund and your federal refund are processed separately and on different timelines. You may receive one before the other. The federal IRS typically processes returns faster than Colorado, so your federal refund might arrive within 21 days while your state refund takes 4 to 6 weeks.

If you owe Colorado taxes but are due a federal refund, the IRS may hold your federal refund to offset what you owe the state. This is called a tax offset. The Department of Revenue will notify you by mail if this happens. The process adds 2 to 4 weeks to your timeline.

What happens if the Department of Revenue finds an error on your return

If the Department of Revenue discovers an error—such as a math mistake, a missing form, or unreported income—they will send you a letter explaining the issue and the adjustment they're making to your refund. You have 30 days to respond if you disagree with their findings. If you don't respond, they will process the return as corrected and send you the adjusted refund amount.

Some errors result in a smaller refund than you expected. Others may mean you owe money instead of receiving a refund. The letter will explain whether you need to pay and by what date. If you cannot pay in full, you can request a payment plan through the Department of Revenue.

Frequently Asked Questions

Can I check my Colorado refund status without my exact refund amount?

No. The "Where's My Refund?" tool requires your Social Security number, filing status, and the exact refund amount shown on your return. If you don't have the amount, check your copy of the return you filed or contact the Department of Revenue at 303-238-TAXI (8299) and they can look it up for you.

Why does the tracker say my return is approved but I still haven't received the money?

Approved means the Department of Revenue has finished reviewing your return and authorized the refund. It does not mean the money has left their account yet. Direct deposits take 3 to 5 business days after approval; checks take 7 to 10 business days for mail delivery. If it's been longer than that, contact the Department of Revenue to confirm the payment was actually sent.

What if I filed my return electronically but the tracker shows no activity after two weeks?

Electronic returns typically appear in the tracker within 7 to 10 days of filing. If yours hasn't shown up after two weeks, there may be an error with your filing. Call the Department of Revenue at 303-238-TAXI (8299) to confirm they received your return and whether there are any issues preventing processing.

Can I get my refund faster if I call the Department of Revenue?

No. Calling does not speed up processing. The Department of Revenue processes returns in the order they're received, and the timeframe depends on whether you filed electronically or by mail and whether your return requires additional review. Calling is useful only if your refund is overdue or if you need to report a problem.

What should I do if I think someone filed a fraudulent return using my Social Security number?

Contact the Colorado Department of Revenue immediately at 303-238-TAXI (8299) and explain the situation. They will flag your account and investigate. You should also file a report with the Federal Trade Commission at identitytheft.gov. Do not ignore this—fraudulent returns can affect your tax record for years.
