How to find your Missouri refund using MO.gov

Missouri has a single official tool to check your refund status: the Where's My Refund page on the Missouri Department of Revenue website. You reach it by going to dor.mo.gov, finding the "Where's My Refund" link (usually under the Individuals section), and entering your Social Security number and the exact refund amount you expect. The tool then tells you whether your return is still being processed, approved, or sent to your bank.

The refund amount you enter must match exactly what you claimed on your return. If you claimed a $1,200 refund and you enter $1,201, the tool will not find your return. If you are unsure of the amount, check your copy of the return you filed or the confirmation email from your tax software.

The tool updates once per day, usually overnight. Checking multiple times in a single day will show the same status. If your return was filed very recently — within the last week — it may not yet appear in the system at all.

What each status message means

Return received and being processed: Missouri has your return and is reviewing it for errors or missing information. This stage typically lasts one to two weeks for straightforward returns. If the return is incomplete, you will receive a letter at your mailing address asking for the missing piece.

Return approved: Missouri has finished reviewing your return and approved the refund. The money is now in the queue to be sent to your bank or mailed as a check. This stage usually takes three to five business days, though it can take longer during peak filing season (February through April).

Refund sent: Your refund has left the Missouri Department of Revenue. If you chose direct deposit, the money is on its way to your bank account and should arrive within one to three business days. If you chose a paper check, it is in the mail and typically arrives within seven to ten business days, depending on postal service speed in your area.

If the tool says your refund was sent more than two weeks ago and you still have not received it, contact the Missouri Department of Revenue directly at 573-751-3505 or through their website contact form.

Key Takeaways

  • The official Where's My Refund tool is on dor.mo.gov and requires your Social Security number and the exact refund amount from your return.
  • The tool updates once daily and may not show your return for up to a week after you file.
  • Processing typically takes one to two weeks, approval takes three to five business days, and delivery takes one to ten business days depending on whether you chose direct deposit or a mailed check.
  • If your refund was sent more than two weeks ago and has not arrived, contact the Missouri Department of Revenue at 573-751-3505.

Why your refund might be delayed

The most common reason for a delay is an error or missing information on your return. If you claimed a dependent who does not have a valid Social Security number, forgot to sign the return, or listed an income amount that does not match what your employer or bank reported to Missouri, the state will hold the return for review. You will receive a letter explaining what is needed.

A second common cause is a mismatch between your bank account information and your actual account. If you entered the wrong account number or routing number for direct deposit, the refund will be rejected by your bank and sent back to Missouri as a paper check instead. This adds one to two weeks to the timeline.

During peak tax season (February through mid-April), even straightforward returns can take longer because the Missouri Department of Revenue processes thousands of returns per day. If you filed in March or April, expect the full timeline — processing, approval, and delivery — to take four to six weeks rather than two to three.

What to do if the tool shows no results

If you enter your information and the tool says it cannot find your return, first check that you are using the correct Social Security number and refund amount. A common mistake is entering a spouse's Social Security number when the return was filed under your name, or vice versa.

If the information is correct and the tool still shows no results, your return may not yet be in the system. Returns typically appear in the Where's My Refund tool within five to seven business days of filing. If you filed less than a week ago, wait a few more days and try again.

If you filed more than a week ago and the tool still shows nothing, contact the Missouri Department of Revenue at 573-751-3505. Have your return confirmation number ready — this is the number your tax software gave you when you filed, or the number on the acknowledgment letter if you filed by mail.

Direct deposit versus mailed checks

If you chose direct deposit on your return, your refund goes straight to your bank account once Missouri approves it. This is the fastest method and typically takes one to three business days after approval. Your bank may hold the deposit for one additional business day before making it available, depending on their policy.

If you chose a mailed check, Missouri prints and mails the check after approval. Delivery time depends on where you live and how busy the postal service is. In urban areas, checks typically arrive within seven to ten business days. In rural areas, it may take longer. The Where's My Refund tool will tell you when the check was mailed, but it cannot track the check itself once it enters the mail system.

If you chose direct deposit but the refund was rejected by your bank (usually because of an incorrect account number), Missouri automatically converts it to a mailed check. You will not see this happen in the Where's My Refund tool — you will straightforward receive a check in the mail instead of a deposit. If this happens, the timeline resets and you should expect the check within seven to ten business days of the rejection.

Frequently Asked Questions

How long does it usually take to get a Missouri refund?

From the time you file to the time the money reaches your account or mailbox, expect two to four weeks for a straightforward return filed outside of peak season. During February through April, add one to two weeks. Direct deposit is faster than mailed checks by about a week.

Can I check my refund status by phone?

No. Missouri does not have a phone line for refund status checks. The Where's My Refund tool on dor.mo.gov is the only way to check. You can call 573-751-3505 if your return is missing from the system or if you have a specific problem, but the automated phone system does not provide status updates.

What if I made a mistake on my return after I filed it?

If you filed electronically and realize you made a mistake before your refund is approved, you can file an amended return (Form MO-1040-X) once you receive your original refund. Do not try to stop the original return. If you filed by mail and catch the error before processing is complete, call the Missouri Department of Revenue when ready at 573-751-3505.

Why does the tool say my refund was sent but I haven't received it?

If you chose direct deposit, check with your bank — the deposit may be pending or held for one business day. If you chose a mailed check and it has been more than ten business days, the check may have been lost in the mail. Contact the Missouri Department of Revenue with your return confirmation number and they can issue a replacement check.

Can I change my bank account after I file but before I get my refund?

No. Once you file, the bank account information is locked in. If you need to change it, you must file an amended return after you receive the original refund, then request a refund to the new account. This adds several weeks to the process.
