How to check the status of your Missouri state tax refund
The Missouri Department of Revenue runs a tool called Where's My Refund that shows you exactly where your state refund is in the process. You enter your Social Security number, filing status, and the refund amount you expect, and the system tells you whether it has been received, is being processed, or has been issued.
Go to dor.mo.gov and look for the "Where's My Refund" link on the homepage. The tool updates once per day, usually overnight, so checking multiple times in a single day will not show new information. If you filed electronically, the system typically has your information within 24 hours of acceptance. If you mailed a paper return, allow 2 to 3 weeks before the system recognizes it.
The tool will show one of four statuses: received (your return arrived and is waiting to be processed), processing (the department is reviewing your return), issued (your refund has been approved and sent), or a message that no record exists yet. If no record appears after the expected timeframe, your return may not have reached the department, or there may be a problem with how you entered your information.
Key Takeaways
- Missouri's Where's My Refund tool at dor.mo.gov shows your refund status using your Social Security number, filing status, and expected refund amount.
- Electronic returns appear in the system within 24 hours of acceptance; paper returns take 2 to 3 weeks to show up.
- The system updates once per day, so checking repeatedly on the same day will not show progress.
- If your refund was issued, the delivery method (direct deposit or check) determines how long until the money reaches you.
- Contact the Missouri Department of Revenue at 573-751-3505 if your return does not appear in the system after the expected wait time.
Typical timelines from filing to receiving your refund
Missouri processes most refunds within 21 days of accepting your return, though the total time from filing to receiving money depends on how you file and how you want the refund delivered.
If you filed electronically and chose direct deposit, the refund usually reaches your bank account within 21 days of the department accepting your return. If you filed electronically but requested a check, allow an additional 7 to 10 business days after the refund is issued for the check to arrive by mail. If you mailed a paper return, add 2 to 3 weeks for the department to receive and enter it into the system before the 21-day processing clock starts.
These are typical timelines, not guarantees. Returns with errors, missing information, or that trigger additional review can take longer. Returns filed late in the tax season (after April 1) may also experience delays because the department handles higher volume.
What to do if your refund is delayed beyond the expected timeframe
If the Where's My Refund tool shows your return was received more than 21 days ago but still shows "processing," or if no record of your return appears in the system after waiting the appropriate time, contact the Missouri Department of Revenue directly.
Call 573-751-3505 during business hours (Monday through Friday, 8 a.m. to 5 p.m. Central Time). Have your Social Security number, filing status, and expected refund amount ready. The department can tell you whether your return is stuck in processing, whether there is an error that needs correction, or whether your return never arrived.
If you mailed your return and it has been more than 5 weeks since you sent it, the department may not have received it. Ask whether you should file electronically instead or resubmit a paper copy. Keep any proof of mailing (such as a receipt from certified mail) in case you need to show when you sent the original.
Direct deposit versus check delivery and how each affects timing
Missouri offers two ways to receive your refund: direct deposit into your bank account or a paper check mailed to your address. Direct deposit is faster and more reliable.
With direct deposit, once the department issues your refund, the money typically reaches your bank within 1 to 3 business days. Your bank may hold the deposit for an additional day depending on its policies, but the refund is out of the state's hands quickly. You provide your routing number and account number when you file, and the department sends the money electronically.
With a check, the department prints and mails the check after issuing the refund. Delivery takes 7 to 10 business days depending on mail speed and your location. Checks can be lost or delayed in the mail, and if yours does not arrive within 10 business days of the refund being issued, you will need to contact the department to request a replacement or a direct deposit instead.
Reasons your Missouri refund might be held or delayed
The Missouri Department of Revenue holds refunds for several specific reasons. The most common is that you owe money to the state — back taxes, child support, or other debts. The department will offset your refund to pay what you owe and send you only the remainder, if any. This process adds time to your refund.
Another reason is an error or inconsistency on your return. This might be a mismatch between the income you reported and what employers or financial institutions reported to the state, a missing or incorrect Social Security number, or a calculation error. The department will contact you by mail if this happens, and you will need to respond before processing can continue.
If you claimed a refundable credit (such as the Earned Income Tax Credit), the department may hold your refund for additional review. Federal law requires states to verify these credits before issuing refunds, which can add 1 to 2 weeks to the timeline.
What happens if your refund was issued but you never received it
If the Where's My Refund tool shows your refund was issued but you have not received it, the next step depends on whether you chose direct deposit or a check.
For direct deposit, check your bank account first — the deposit may have posted but not yet shown in your available balance. If 3 business days have passed since the refund was issued and the money is not in your account, contact your bank to ask whether the deposit was received. If your bank has no record of it, call the Missouri Department of Revenue at 573-751-3505 with the refund issue date and ask them to verify the routing and account number they have on file. A typo in either number will cause the deposit to fail, and the department can reissue the refund by check or correct the account information and try again.
For a check, wait 10 business days from the issue date before assuming it is lost. If it does not arrive within that window, contact the department and request a replacement. They can issue a new check or convert the refund to direct deposit if you provide correct banking information.
Frequently Asked Questions
Can I check my refund status without using the online tool?
Yes. Call the Missouri Department of Revenue at 573-751-3505 and provide your Social Security number, filing status, and expected refund amount. A representative can look up your status and tell you the same information the online tool shows. Phone lines are open Monday through Friday, 8 a.m. to 5 p.m. Central Time.
What if I filed an amended return — does that change my refund timeline?
Yes. An amended return (Form MO-1040X) restarts the processing timeline. The department must process your original return first, then review your amendment. This typically adds 4 to 8 weeks to the total time. The Where's My Refund tool will show the status of your amended return once it is received.
Why does the Where's My Refund tool say no record found even though I filed?
This usually means either the return has not reached the department yet (if you mailed it, wait 2 to 3 weeks), or you entered one of the three pieces of information incorrectly. Double-check your Social Security number, filing status (single, married filing jointly, etc.), and the exact refund amount. If you are certain the information is correct, call 573-751-3505 to confirm the return was received.
Can the state take my refund to pay child support or other debts?
Yes. Missouri will offset your refund to pay back taxes, child support arrears, or other debts owed to the state. The department will notify you by mail if this happens and will tell you how much of your refund was taken and why. You can dispute the offset if you believe it is incorrect.
How long should I wait before calling about a missing refund?
For direct deposit, wait 3 business days after the refund was issued. For a check, wait 10 business days. If you have not received the money by then, contact the Missouri Department of Revenue at 573-751-3505 to report it and request a replacement or reissue.
