How to track your Missouri state tax refund

Missouri's Department of Revenue runs a refund tracker called Where's My Refund? on its website. 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, approved, or sent out. The tool updates every business day and covers both individual income tax refunds and corporate tax refunds.

You can reach the tracker at dor.mo.gov under the "Individuals" or "Businesses" section, depending on what you filed. The page is straightforward — no login required, and it takes about two minutes. If your return was filed electronically, the tracker usually has information within 24 hours of the Missouri Department of Revenue receiving it. Paper returns take longer to enter the system, usually 4 to 6 weeks after you mail them.

The tracker shows one of four statuses: received (your return arrived and is in the queue), processing (it's being reviewed), approved (the refund has been authorized), or sent (the money has been issued). If it says "sent," the refund is either on its way by mail or has been deposited to your bank account, depending on how you requested it.

Key Takeaways

  • Missouri's Where's My Refund tool is free and requires only your Social Security number, filing status, and refund amount.
  • The tracker updates every business day and shows whether your refund is received, processing, approved, or sent.
  • Electronic returns appear in the system within 24 hours; paper returns take 4 to 6 weeks to enter the queue.
  • If your refund shows as "sent," check your bank account first before assuming it's still in the mail.

What each refund status means

Received means the Missouri Department of Revenue has your return in its system but hasn't started reviewing it yet. This is the first status you'll see, and it can last anywhere from a few days to several weeks depending on how busy the department is. During tax season (January through April), the received stage is longer because the volume is high.

Processing means a department employee is reviewing your return for accuracy, checking that your numbers match what employers and financial institutions reported, and verifying that you didn't claim something twice. This stage typically takes 2 to 4 weeks for straightforward returns. Returns with errors, missing information, or items that need manual review can stay in processing much longer.

Approved means the department has finished reviewing your return and determined the refund amount is correct. The refund has been authorized and is queued to be sent out. This stage is usually brief — often just a few days — but during peak season it can take longer because the department processes refunds in batches.

Sent means the refund has left the department. If you chose direct deposit, the money has been sent to your bank and should arrive within 1 to 3 business days. If you chose a paper check, it's in the mail and typically arrives within 7 to 10 business days, though mail delivery times vary by location.

How long Missouri refunds typically take

A straightforward electronic return filed in January or February usually receives a refund within 3 to 5 weeks. A return filed in March or April can take 6 to 8 weeks because the department is processing thousands of returns simultaneously. Paper returns take longer at every stage — add 2 to 4 weeks just for the return to be entered into the system, then add the normal processing time on top of that.

Returns that trigger a manual review — because of math errors, missing documents, or items that don't match third-party reports — can take 8 to 12 weeks or longer. The department will contact you by mail if your return needs additional information. Do not wait for that letter to respond; if you know something on your return might need explanation, contact the department proactively.

Direct deposit refunds arrive faster than paper checks. If your refund shows "sent" and you chose direct deposit, expect the money in your bank account within 1 to 3 business days. If you chose a check and it's been more than 10 business days since the status changed to "sent," contact the department to confirm the address they have on file.

What to do if your refund is delayed

First, check the Where's My Refund tracker again. Refresh the page and re-enter your information to make sure you're seeing the current status. Sometimes the page doesn't update when ready in your browser. If the status hasn't changed in more than 60 days from when you filed, or if it's been more than 10 business days since it showed "sent" and you haven't received the money, contact the Missouri Department of Revenue directly.

You can reach the department by phone at 573-751-3505 (individual income tax) or 573-751-4541 (corporate tax). Have your Social Security number, filing status, and the refund amount ready. The phone lines are busiest during tax season, so call early in the morning or in the afternoon after lunch if you can. You can also mail a written inquiry to the Missouri Department of Revenue, Taxation Division, P.O. Box 311, Jefferson City, MO 65105, but a phone call is faster.

If your refund was supposed to be direct deposited but never arrived, ask the department to verify the bank account number on file. Typos happen, and if a digit is wrong, the refund goes to the wrong account. The department can reissue the refund to the correct account, but it takes time. If the account number is correct, contact your bank to ask whether the deposit was rejected or returned.

Direct deposit versus paper check refunds

When you file your return, you choose how you want to receive your refund. Direct deposit means the money goes straight into a bank account you specify. This is faster — usually 1 to 3 business days after the status changes to "sent" — and more reliable because there's no mail to get lost. You can use a checking account, savings account, or even a prepaid debit card, as long as the financial institution accepts ACH transfers.

A paper check is mailed to the address on your return. It typically arrives within 7 to 10 business days after the status changes to "sent," but mail delivery times vary. If you moved after filing, the check goes to the address the department has, not your current address. If you think your check got lost in the mail, wait 15 business days after the status changed to "sent," then contact the department to request a replacement.

Direct deposit is the faster and safer option if you have a bank account. If you don't have a bank account, a paper check is your only choice, but be aware that it takes longer and can be lost or stolen from your mailbox.

If your refund amount seems wrong

Before you contact the department, review your return and the notice the department sent you (if any). Common reasons for a smaller refund than expected include: you owed state taxes from a prior year and the refund was applied to that debt, you claimed a dependent who also filed a return, or you had income the department didn't expect. The department's notice will explain the adjustment if one was made.

If you believe the refund amount is genuinely incorrect — for example, you reported income that wasn't actually yours, or the department subtracted an amount you don't understand — contact the department with your return and the notice side by side. Be specific about which line item you think is wrong. The department will review your return again and either confirm the amount or issue a corrected refund.

If you filed an amended return (Form MO-1040X), the refund from that amended return is tracked separately. Check the Where's My Refund tool for the amended return using the same process. Amended returns take longer to process — typically 8 to 12 weeks — because they require manual review.

Frequently Asked Questions

Can I check my refund status without my Social Security number?

No. The Where's My Refund tool requires your Social Security number, filing status, and the exact refund amount as they appear on your return. This is a security measure to prevent someone else from looking up your refund. If you don't remember the refund amount, check your copy of the return you filed or the confirmation email if you filed electronically.

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

If you chose direct deposit, check your bank account — the money may have arrived but not posted yet, or it may have gone to a different account if there was a typo in the account number. If you chose a paper check, allow 10 business days for mail delivery. If more than 10 business days have passed, contact the department to confirm the address and request a replacement check if needed.

How do I know if my return is being audited?

The Where's My Refund tracker does not show audit status. If the department is auditing your return, they will contact you by mail with a notice explaining what they need. Do not ignore the notice. Respond within the timeframe given, usually 30 days. If you receive an audit notice, you can also call the department at 573-751-3505 to ask questions about what they're reviewing.

Can I get my refund faster if I pay a fee?

No. The Missouri Department of Revenue does not offer expedited refund processing for a fee. The timeline depends on how busy the department is and whether your return needs manual review. Direct deposit is the fastest method available at no extra cost.

What if I filed my return but the tracker shows no record of it?

If you filed electronically, the tracker should show your return within 24 hours. If it doesn't, double-check that you entered your Social Security number and filing status correctly. If you filed a paper return, it takes 4 to 6 weeks to enter the system. If more than 6 weeks have passed since you mailed it, contact the department to confirm they received it.
