Check your refund status on the Missouri Department of Revenue website

The Missouri Department of Revenue runs a tool called Where's My Refund? that shows you exactly where your state tax refund is in the process. You can find it on the department's website by searching "Missouri Where's My Refund" or going directly to the refund tracker.

To use it, you will need your Social Security number, filing status (single, married filing jointly, etc.), and the exact refund amount from your tax return. The tool tells you whether your return is still being processed, has been approved, or has already been sent to your bank or mailed as a check.

The tracker updates once per day, usually overnight. If you just filed your return, it may take a few days to appear in the system at all — the department needs time to receive and scan your paperwork first.

Key Takeaways

  • Missouri's Where's My Refund tool on the Department of Revenue website is the official source for your refund status and requires your Social Security number and refund amount.
  • Refunds typically arrive within 21 days of approval if you chose direct deposit, or within four to six weeks if you requested a mailed check.
  • If your refund is delayed beyond the normal timeframe, contact the Department of Revenue directly rather than waiting — they can investigate specific cases.
  • A refund that shows as approved but has not arrived after the expected time may indicate a banking issue, so check with your bank before contacting the state.

How long Missouri refunds usually take

The timeline depends on how you filed and how you want to receive your money. If you filed electronically and chose direct deposit (the refund goes straight into your bank account), the state typically sends it within 21 days of approving your return. If you requested a mailed check instead, allow four to six weeks from approval.

Paper returns filed by mail take longer to process because the department has to receive them, open them, and enter the information into their system. These often take six to eight weeks total before the refund is even approved, and then another four to six weeks to arrive as a check.

The busiest time for the Missouri Department of Revenue is February through April, when most people file. Refunds may move more slowly during these months straightforward because the volume is higher.

What to do if your refund is taking longer than expected

First, check the Where's My Refund tool again to confirm the current status. If it shows your refund was approved and sent via direct deposit more than 21 days ago, contact your bank to ask whether the deposit arrived and was rejected for any reason — sometimes a closed account or incorrect routing number causes the state's payment to bounce back.

If your bank confirms they never received the deposit, or if the tool shows your return is still being processed after eight weeks, contact the Missouri Department of Revenue directly. You can reach them by phone at 573-751-3505 during business hours, or use the contact form on their website. Have your Social Security number, filing status, and the refund amount ready when you call.

The department can see notes on your specific return that the online tool does not show — for example, whether they are waiting for additional information from you, or whether there is a problem with your bank details on file.

Why your refund might be delayed

The most common reason for a delay is a mismatch between the information on your return and what the state has on file. This might be a name spelled differently, a Social Security number entered wrong, or a filing status that does not match your previous year's return. The department catches these during processing and may need to contact you to clarify.

Another frequent cause is a math error on the return itself. If you claimed deductions or credits that the state's system flags as unusual for your income level, they may hold the return for manual review. This is not a problem — it just takes longer.

If you owe back taxes, child support, or student loans, the state may hold your refund to offset what you owe. The Where's My Refund tool will not always tell you this directly, so if your refund disappears from the tracker, contact the department to ask whether an offset was applied.

Direct deposit versus mailed check

Choosing direct deposit when you file is the fastest way to receive your refund. The state sends the money electronically to your bank, and it typically arrives within 21 days of approval. You need a valid bank account number and routing number to use this option.

If you request a mailed check instead, the state prints and mails it from their office. This adds four to six weeks to the timeline because of postal delivery. Checks can also be lost or delayed in the mail, which is why direct deposit is generally more reliable.

If you filed without choosing direct deposit and now want to change it, you cannot do so through the Where's My Refund tool. You would need to contact the Department of Revenue to see whether they can update your banking information before the refund is sent. Call 573-751-3505 to ask.

What information you need to check your status

Have these three pieces of information ready before you use the Where's My Refund tool: your Social Security number, your filing status as it appears on your return (single, married filing jointly, married filing separately, or head of household), and the exact refund amount you claimed on your return.

The refund amount is the most important piece — if you enter it wrong, the tool will not find your return. Check your copy of the return you filed, or look at the confirmation email or letter you received from the state if you filed electronically.

If you cannot find your refund amount or do not have your Social Security number available, you can still contact the Department of Revenue by phone and they can look up your return using your name and address instead.

Frequently Asked Questions

Can I check my federal and state refund status in the same place?

No. Your federal refund is tracked through the IRS website (IRS.gov), and your Missouri state refund is tracked through the Missouri Department of Revenue website. They are separate systems, so you need to check both if you filed both a federal and state return.

What if the Where's My Refund tool says my return is still processing after three months?

Contact the Department of Revenue at 573-751-3505. A return should not take that long unless there is a specific problem — a missing document, an error that needs correction, or an offset being applied. The department can tell you what is holding it up and what you need to do next.

If I filed a paper return, can I still use the Where's My Refund tool?

Yes, once the department has processed your paper return and entered it into their system, it will show up in the tool. This usually takes two to three weeks after they receive it. Until then, the tool will not find your return, which is normal.

What happens if my bank account information was wrong on my return?

If you chose direct deposit but entered the wrong account number or routing number, the state's payment will be rejected by your bank and sent back to the department. They will then mail you a check instead, which adds four to six weeks to the timeline. Contact the department when ready if you think you made this error.

Can I get my refund faster by paying a fee?

No. The Missouri Department of Revenue does not offer expedited refund processing for any fee. The timeline is the same for everyone — 21 days for direct deposit or four to six weeks for a mailed check, once your return is approved.
