Check your refund status on the Missouri Department of Revenue website

The Missouri Department of Revenue operates a refund tracker where you can see the status of your state tax refund. Go to dor.mo.gov and look for the "Where's My Refund?" tool on the homepage. 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 updates once per day, usually overnight. If you filed electronically, your refund typically processes within 21 days. If you filed on paper, allow 4 to 6 weeks. The tracker will show you whether your return is still being processed, has been approved, or has been sent to your bank or mailed as a check.

If the tracker shows your refund was sent but you have not received it, note the date it says it was mailed or deposited. Paper checks can take 7 to 10 business days to arrive after the Department of Revenue sends them. Direct deposits usually arrive within 2 to 3 business days.

What causes delays in Missouri tax refunds

The most common reason for a delayed refund is a mismatch between the information on your return and the Department of Revenue's records. This includes your name, Social Security number, filing status, or income reported by your employer. The Department will contact you by mail if they need you to verify information before they can process your refund.

Claiming certain credits—particularly the Earned Income Tax Credit or the Child and Dependent Care Credit—can also add processing time. These credits require extra verification. If you claimed a credit you are unsure about, check your return to see what you reported.

Paper returns take longer than electronic ones because they must be manually scanned and entered into the system. If you filed on paper and it has been more than 6 weeks, call the Department of Revenue to confirm they received your return.

What to do if your refund is missing or never arrived

First, confirm the refund was actually sent. Log into the "Where's My Refund?" tool again and take note of the exact date and method (check or direct deposit). If it shows as sent more than 10 business days ago and you still have not received it, the next step depends on whether it was mailed or deposited electronically.

For a mailed check, wait the full 10 business days before taking action. If it still has not arrived, contact the Missouri Department of Revenue at 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 the refund amount ready. The Department can verify whether the check was cashed and, if not, issue a replacement.

For a direct deposit that shows as sent but never arrived, check your bank account carefully—sometimes deposits post under a different date than expected or to a linked account you do not use regularly. If you are certain it did not arrive, contact your bank first to confirm they did not receive it. Then call the Department of Revenue with your bank routing and account numbers so they can investigate on their end.

How to prevent refund problems on your next return

File electronically rather than on paper. Electronic returns process faster and have fewer errors because the software catches common mistakes before you submit. If you cannot file electronically yourself, the IRS Free File program and many tax preparation software companies offer free or low-cost electronic filing.

Double-check that your name, Social Security number, and filing status match exactly what is on your Social Security card and driver's license. Typos in these fields are one of the most common reasons for delays. If you recently changed your name, make sure you have updated it with Social Security before filing.

Report only income that matches what your employer or bank reported to the IRS and Missouri Department of Revenue. If you received a W-2, 1099, or other income document, the amounts on your return should match those documents exactly. Mismatches trigger manual review and delay processing.

Understanding direct deposit versus check refunds

Direct deposit is faster and more reliable than a mailed check. If you choose direct deposit, your refund arrives in your bank account within 2 to 3 business days after the Department of Revenue approves it. You will need your bank's routing number and your account number to set this up on your return.

A mailed check takes longer because it must be printed, stuffed, and delivered by postal mail. Even after the Department of Revenue sends it, you should expect 7 to 10 business days for it to arrive. Checks can also be lost or stolen in the mail, which is why direct deposit is the safer option if your bank account is stable.

If you are unsure whether you set up direct deposit correctly, the "Where's My Refund?" tool will show you which method the Department used. If it shows a check was sent and you prefer direct deposit for future years, make a note to set it up on next year's return.

Contact information and resources

The Missouri Department of Revenue's main phone line is 573-751-3505. They handle questions about state tax refunds, processing delays, and missing payments. Hours are Monday through Friday, 8 a.m. to 5 p.m. Central Time. Have your Social Security number, filing status, and the refund amount ready when you call.

You can also mail a written inquiry to the Missouri Department of Revenue, P.O. Box 311, Jefferson City, MO 65105. Include your name, Social Security number, filing status, and a description of your issue. Written inquiries take longer to process than phone calls, so call if your refund is urgent.

The Department of Revenue website at dor.mo.gov has additional resources, including answers to common questions and links to tax forms. If you filed a federal return as well, you can track your federal refund separately through the IRS website at irs.gov.

Frequently Asked Questions

How long does Missouri take to process a tax refund?

Electronic returns typically process within 21 days. Paper returns take 4 to 6 weeks from the date the Department of Revenue receives them. If you claimed certain credits like the Earned Income Tax Credit, add an extra week or two for verification. The "Where's My Refund?" tool shows your current status.

Can I get my refund faster if I file early?

Filing early does not speed up processing time. The Department of Revenue processes returns in the order they are received, and processing time is the same whether you file in January or April. However, filing early means you will receive your refund sooner in the calendar year.

What should I do if the refund tracker says my return is still being processed after 21 days?

Call the Missouri Department of Revenue at 573-751-3505. Your return may be held for verification if there is a discrepancy in your information or if you claimed a credit that requires extra review. The Department can tell you what is needed and how long it will take.

Can I cancel my refund and get the money a different way?

Once the Department of Revenue has approved and sent your refund, you cannot cancel it. If you set up direct deposit and want to change the account, you must wait until next year's return. If a check was mailed and you want to redirect it, contact the Department of Revenue when ready with your new address.

What if I filed jointly with my spouse and only one of us received the refund?

Contact the Missouri Department of Revenue with both Social Security numbers and your filing status. Refunds on joint returns are sometimes split between accounts if both spouses set up separate direct deposits. The Department can confirm where each portion was sent and help resolve any issues.
