Check your refund status through the Missouri Department of Revenue website

The Missouri Department of Revenue runs a tool called Where's My Refund that shows you the status of your state tax refund in real time. You reach it through the department's main website at dor.mo.gov. The tool tells you whether your refund has been received, is being processed, has been approved, or has been issued.

To use Where's My Refund, you need three pieces of information: your Social Security number, your filing status (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 number from your tax form itself — the amount you expected to receive back, not the amount you paid in taxes.

The tool updates once per day, usually overnight. If you filed electronically, your return typically appears in the system within 24 hours. If you mailed a paper return, it may take several weeks before it shows up in the tool at all.

Key Takeaways

  • Where's My Refund is on the Missouri Department of Revenue website and shows your refund status in real time using your Social Security number, filing status, and refund amount.
  • The tool updates once per day and shows whether your return is received, being processed, approved, or issued.
  • Electronic returns usually appear in the system within 24 hours; paper returns can take several weeks to show up.
  • If your refund status does not change for more than 30 days, contact the department directly because your return may need correction or verification.
  • Direct deposit refunds typically arrive within one to three business days after the status shows "issued"; paper checks take two to four weeks.

What each refund status means

When you check Where's My Refund, you will see one of four statuses. Return Received means the Missouri Department of Revenue has your return but has not started processing it yet. This is the first status you see after filing, and it can last anywhere from a few days to several weeks depending on how many returns the department is handling.

Return Being Processed means the department is reviewing your return for accuracy and checking that all required information is there. This stage involves verifying your income against W-2s and 1099s, checking for math errors, and confirming your identity. Most returns move through this stage without problems, but if the department finds an issue, they will send you a letter asking for more information or explaining a change they made.

Return Approved means the department has finished reviewing your return and found no problems. Your refund amount is final at this point. The department is now preparing to send the money to you — either by direct deposit or by mailing a check.

Refund Issued means the money has left the state treasury and is on its way to you. If you chose direct deposit, the refund typically arrives in your bank account within one to three business days. If you are receiving a paper check, allow two to four weeks for it to arrive by mail.

Why your refund status might not update

If your status has not changed in more than 30 days, something is holding up your return. The most common reasons are missing or incorrect information on your return, a mismatch between what you reported and what the IRS reported to Missouri, or identity verification issues.

When the department needs more information from you, they send a letter to the address on your return. Check your mail carefully, including your spam folder if you signed up for email notifications. The letter will explain exactly what is missing or what does not match, and it will tell you how to respond.

If you have not received a letter after 30 days and your status is still stuck on "Return Being Processed," contact the Missouri Department of Revenue directly. Call their individual income tax line at 573-751-2356 during business hours (Monday through Friday, 8 a.m. to 5 p.m. Central Time). Have your Social Security number, filing status, and refund amount ready when you call.

What to do if your refund is delayed past the expected arrival date

If your status shows "Refund Issued" but the money has not arrived after the expected timeframe, first check with your bank. Sometimes refunds are delayed on the receiving end — your bank may be holding the deposit for verification, or there may be a processing delay on their side. Call your bank's customer service line and give them the date the refund was issued according to Where's My Refund.

If your bank confirms they have not received the deposit, or if you are waiting for a paper check that has not arrived after four weeks, contact the Missouri Department of Revenue again. They can tell you whether the refund was actually sent and, if it was, help you file a claim for a lost or stolen check. If the refund was never sent despite showing "Issued," the department will investigate why and reissue it.

Refund timing for different filing methods

How long your refund takes depends on whether you filed electronically or by mail, and whether you chose direct deposit or a paper check. Electronic filers who choose direct deposit typically see their refund within 21 days of filing, though it can be faster. Electronic filers who requested a paper check usually wait 21 to 30 days. Paper filers should expect 6 to 8 weeks from the date they mailed their return, because the department has to receive it, open it, scan it, and enter the information into their system before processing even begins.

These timelines assume no problems with your return. If the department needs to verify information or correct an error, add at least two to four weeks to the timeline. During tax season (January through April), processing times are slower because the department is handling a much higher volume of returns.

Frequently Asked Questions

Can I check my refund status on my phone?

Yes. The Missouri Department of Revenue's Where's My Refund tool works on mobile browsers. Go to dor.mo.gov on your phone's web browser and look for the refund status link. You do not need to download an app — the website is mobile-friendly.

What if I filed jointly with my spouse but only have one Social Security number?

Use the Social Security number of the person whose name appears first on the return. The tool will show the status of the joint return. If you need to know the status and cannot remember whose name is first, check a copy of the return you filed or contact the Missouri Department of Revenue.

Can I get my refund faster if I call the department?

No. Calling the department does not speed up processing. The department processes returns in the order they receive them, and calling does not move your return to the front of the line. Calling is useful only if your status has not changed in 30 days or if your refund is late after being issued.

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

If you filed electronically and realize you made a mistake before the department has issued your refund, you can file an amended return (Form MO-1040-X) to correct it. If you filed by mail, wait until the department has processed your original return before filing an amended return. Filing an amended return will delay your refund because the department has to review both returns.

Why does Where's My Refund say my refund amount is different from what I calculated?

The department may have corrected an error on your return, applied a credit you did not claim, or adjusted your refund because of information they received from the IRS or another state. When this happens, the department sends a letter explaining the change. Check your mail for that letter. If you disagree with the change, the letter will tell you how to file a protest or request a review.
