How long Missouri takes to send your refund

Missouri processes most tax refunds within 30 days of receiving your return, but the actual timeline depends on how you file and how you want the money delivered. If you file electronically and choose direct deposit to your bank account, you will typically see the refund within 21 days. If you file on paper or request a check by mail, add another two to three weeks.

The Department of Revenue starts the clock when they receive your return, not when you mail it or hit submit. Paper returns can take five to ten business days to reach their processing center, so the total time from mailing to receiving your refund can stretch to six weeks or longer. Electronic filing cuts that delay in half.

These timelines assume your return has no errors, your income matches what employers reported, and you did not claim anything unusual. If the Department of Revenue flags your return for review—which happens to roughly one in ten returns—add two to four weeks to the timeline.

Key Takeaways

  • Direct deposit of an electronically filed return typically arrives within 21 days of the Department of Revenue receiving your return.
  • Paper returns and mailed checks add two to three weeks to the timeline, bringing the total to four to six weeks or more.
  • The Department of Revenue counts processing time from the date they receive your return, not the date you file, so mail delays matter.
  • You can check your refund status on the Missouri Department of Revenue website using your Social Security number and filing status, usually within 24 hours of filing electronically.
  • If your refund does not arrive within the expected window, contact the Department of Revenue directly rather than waiting longer.

Tracking your refund status online

The Missouri Department of Revenue runs a refund status tool on its website where you can check the progress of your return. You will need your Social Security number, filing status (single, married, head of household), and the exact refund amount from your return. The tool updates once per day, usually overnight.

For electronically filed returns, the status tool typically shows information within 24 hours of filing. For paper returns, allow five to ten business days for the return to be received and entered into the system before status information appears. Once your return is in the system, you can track it from "received" through "processing" to "refund issued."

The status tool will tell you the date your refund was issued, but not the date it will arrive in your account or mailbox. If your refund shows as issued but has not arrived after the expected window, that is when to contact the Department of Revenue directly.

Direct deposit versus check by mail

Direct deposit is the fastest way to receive your refund. The Department of Revenue sends the money to your bank, and it typically appears in your account within 21 days of them receiving your return. You provide your bank account number and routing number on your tax return, and the money goes straight there—no mail delays, no lost checks.

A check by mail takes longer because the Department of Revenue has to print the check, mail it to you, and then you have to deposit it. The check itself is usually mailed within 30 days of processing, but mail delivery adds another one to two weeks depending on where you live. If you live far from Jefferson City or if mail is slow in your area, add extra time.

If you are unsure whether your bank information is correct on your return, do not guess. An incorrect routing number or account number will cause the direct deposit to fail, and the Department of Revenue will mail a check instead—which defeats the purpose of choosing direct deposit. Double-check your bank details before you file.

What delays refunds and what does not

The Department of Revenue will hold your refund if they need to verify information on your return. This happens most often when your reported income does not match what your employer reported to the IRS, when you claim a large deduction or credit, or when you file very early in the tax season. They will contact you by mail if they need more information, and processing resumes once you respond.

Owing money to the state or federal government can also delay your refund. If you owe back taxes, child support, or other debts to Missouri or the federal government, the Department of Revenue may offset your refund to pay those debts. You will receive notice of the offset, but your refund will be reduced or eliminated.

Filing amendments or corrections after you have already filed will restart the processing timeline. If you file an amended return, the Department of Revenue processes it separately, and you should expect another 30 days from the date they receive the amendment.

What to do if your refund is late

If your refund does not arrive within the expected timeframe, start by checking the status tool on the Missouri Department of Revenue website. If the tool shows your refund as issued, but it has been more than three weeks since that date for direct deposit or more than four weeks for a check, contact the Department of Revenue by phone or mail.

The Department of Revenue phone line for refund questions is available during business hours. Have your Social Security number, filing status, and the refund amount ready when you call. They can tell you whether your refund was issued, whether it was offset for a debt, or whether your return is still being processed.

If a check was lost or never arrived, the Department of Revenue can issue a replacement. They will need to verify your identity and confirm that the original check was not cashed. This process usually takes two to four weeks, so a replacement check is not faster than waiting for the original—but it is necessary if you are certain the check was lost.

Refunds and state tax credits

Missouri offers several tax credits that can result in a refund even if you paid no state income tax. The Earned Income Tax Credit (EITC) and the Child and Dependent Care Credit can both produce refunds. These credits are processed the same way as any other refund, so the timeline is the same: 21 days for direct deposit, 30 to 45 days for a check.

If you claim the Missouri Property Tax Credit or the Renter's Property Tax Credit, those are handled separately and may have different processing times. The Department of Revenue will send information about those credits with your refund notice.

Filing early versus filing late in the season

Filing your return in early February typically results in faster processing than filing in late March or April. The Department of Revenue has fewer returns to process in February, so your return moves through the queue more quickly. However, the difference is usually only a few days—not weeks.

Filing very early (in January) can actually slow things down because the Department of Revenue may hold your return until they have received all the documents they need from employers and financial institutions. If you file in January and your return is held, you will not see your refund until February or March anyway.

The safest approach is to file once you have received all your tax documents—your W-2s, 1099s, and any other income statements—rather than trying to time your filing for speed. The processing timeline is predictable enough that filing a week or two later will not make a meaningful difference.

Frequently Asked Questions

Can I get my refund faster if I pay a tax preparation service?

No. Tax preparation services can file your return electronically, which is faster than mailing a paper return, but they cannot speed up the Department of Revenue's processing time. The 21-day timeline for direct deposit is the same whether you file yourself or use a service. Some services offer refund advances or loans, but those are separate products that cost money and are not the same as your actual refund.

What if I filed my return but never got a confirmation?

If you filed electronically, you should receive a confirmation number immediately after submitting. If you did not, your return may not have been submitted successfully. Check your email for a confirmation message, or log back into the filing software to verify the status. If you filed on paper, there is no confirmation—the Department of Revenue will contact you only if they have a problem with your return.

Will my refund be reduced if I owe federal taxes?

No. Missouri and the federal government are separate tax systems. Your Missouri refund will not be affected by what you owe to the IRS. However, your federal refund can be offset to pay Missouri debts, and your Missouri refund can be offset to pay federal debts, through a federal offset program. The Department of Revenue will notify you if an offset occurs.

Can I change my bank account after I file?

No. Once you file your return with a bank account number, the Department of Revenue will send your direct deposit to that account. If the account is closed or the number is wrong, the deposit will fail and the Department of Revenue will mail a check instead. Contact the Department of Revenue immediately if you realize you provided the wrong account information.

How do I know if my return is being audited?

The Department of Revenue will contact you by mail if your return is selected for review or audit. You will not find this information on the status tool. If you receive a letter from the Department of Revenue asking for additional documents or information, respond promptly and keep copies of everything you send. Processing will resume once they receive your response.
