How long Missouri takes to send your refund

Missouri typically processes state tax refunds within 30 days of receiving your return, though the actual timeline depends on how you filed and whether the Department of Revenue needs to verify information on your return. If you filed electronically and chose direct deposit, you are most likely to receive your refund within this window. If you filed on paper or requested a check by mail, add another 5 to 10 business days for processing and delivery.

The Department of Revenue publishes a refund status tool on its website where you can check the exact status of your return using your Social Security number and the refund amount. This tool updates regularly and will show you whether your return is still being processed, has been approved, or has been sent.

Key Takeaways

  • Electronic returns with direct deposit typically arrive within 30 days; paper returns take longer because they must be manually entered and mailed.
  • You can check your refund status on the Missouri Department of Revenue website using your Social Security number and refund amount.
  • If your return requires verification — such as matching income to W-2 forms or resolving discrepancies — processing will take longer than 30 days.
  • Refunds sent by check arrive 5 to 10 business days after the Department of Revenue mails them, depending on postal delivery times.
  • If you have not received your refund within 60 days of filing, contact the Department of Revenue directly rather than waiting.

Why some refunds take longer than 30 days

The Department of Revenue may need additional time if your return contains errors, mismatched information, or claims that require verification. Common reasons for delays include a Social Security number that does not match state records, income reported on your return that differs from what employers reported on W-2 forms, or credits you claimed that the department needs to confirm.

If you claimed the Earned Income Tax Credit (EITC) or the Child and Dependent Care Credit, expect processing to take longer — these credits require additional verification steps. The department will contact you by mail if it needs more information, so check your mailbox regularly during the processing period.

Direct deposit versus check by mail

Direct deposit is the fastest way to receive your refund. When you file electronically and provide your bank account number and routing number, the Department of Revenue deposits your refund directly into your account once it approves your return. This typically happens within 30 days and does not depend on mail delivery times.

If you requested a check by mail, the department must print and mail the check after approving your return. The check then travels through the postal system, which adds 5 to 10 business days. If you did not provide banking information when you filed, the department automatically sends a check.

What to do if your refund is delayed

First, use the refund status tool on the Missouri Department of Revenue website to confirm that your return has been received and is being processed. You will need your Social Security number and the amount of the refund you expect. The tool will tell you whether the department is still reviewing your return, has approved it, or has sent it.

If the status tool shows your return was approved and sent more than 60 days ago, or if the tool shows no record of your return at all, contact the Department of Revenue directly. You can reach them by phone at 573-751-3505 or through their website. Have your Social Security number, filing status, and the refund amount ready when you call.

If you filed on paper

Paper returns take longer to process because a staff member must manually enter the information into the system before the department can review it. The Department of Revenue estimates 30 days for processing after the return arrives, but mail delivery to Jefferson City can add several days on the front end.

If you mailed your return and want to track it, you cannot do so through the postal service — the department does not provide a way to confirm receipt of a paper return before it enters the system. Once it is entered, it will appear in the refund status tool. If you filed on paper more than 45 days ago and still see no record in the status tool, call the department to confirm they received it.

Refunds held for other debts

Missouri may hold your refund if you owe money to the state in other areas — such as unpaid child support, student loan debt, or unemployment insurance overpayments. The Department of Revenue does not send your refund until these debts are resolved or a payment plan is in place.

If your refund is being held, the department will notify you by mail explaining the reason and the steps you need to take. If you believe your refund is being held in error, or if you have questions about the debt, contact the Department of Revenue or the agency that reported the debt.

Frequently Asked Questions

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

No. The Missouri Department of Revenue does not offer expedited processing for a fee. The timeline depends on how you filed and whether your return requires verification. Direct deposit is the fastest method available at no extra cost.

What if I filed electronically but still have not received my refund after 45 days?

Check the refund status tool first to see whether the department has approved and sent your refund. If the tool shows it was sent, contact your bank to confirm the deposit did not arrive in error. If the tool shows processing is still underway, call the Department of Revenue at 573-751-3505 to ask whether your return requires additional verification.

Do I need to do anything to receive my refund, or does it come automatically?

Your refund comes automatically once the department approves your return. You do not need to take any action. If the department needs more information, it will contact you by mail with instructions.

What happens if the postal service loses my refund check?

If your check does not arrive within 10 business days of the status tool showing it was sent, contact the Department of Revenue. They can issue a replacement check or deposit the refund directly to your bank account if you provide that information.
