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 filed and how you want the money delivered. If you filed electronically and chose direct deposit to your bank account, you will typically see the refund between 7 and 21 days after the Missouri Department of Revenue accepts your return. Paper returns take longer — usually 6 to 8 weeks — because they must be manually processed and entered into the system.

The 30-day window is not a may provide; it is the standard timeframe Missouri aims for during normal processing periods. If you filed early in the tax season (January or February), your refund may arrive faster because the department has fewer returns in the queue. If you filed closer to the April deadline, processing can take the full 30 days or slightly longer, especially if your return needs manual review.

Direct deposit is always faster than a paper check. If you chose to receive a check by mail, add another 5 to 10 business days for postal delivery after the department issues it.

Key Takeaways

  • Electronic returns with direct deposit typically arrive within 7 to 21 days of acceptance by the Missouri Department of Revenue.
  • Paper returns take 6 to 8 weeks to process, and mailed checks add another 5 to 10 business days for delivery.
  • You can track your refund status using the "Where's My Refund?" tool on the Missouri Department of Revenue website with your Social Security number and refund amount.
  • If your return requires manual review — for example, because of missing information or a mismatch in your filing — processing will take longer than the standard timeline.
  • Refunds issued during peak filing season (late March through mid-April) may take the full 30 days or longer.

How to track your Missouri refund status

The Missouri Department of Revenue operates a Where's My Refund? tool on its website at dor.mo.gov. To use it, you will need your Social Security number, your filing status, and the exact amount of the refund you expect. The tool updates once per day, usually overnight, so checking multiple times in a single day will not show new information.

The tool will show you one of four statuses: "Return Received," "Return Accepted," "Refund Issued," or "Refund Delivered." "Return Received" means the department has your return but has not yet reviewed it. "Return Accepted" means your return passed the initial review and is in the processing queue. "Refund Issued" means the department has approved your refund and sent it to your bank or printed a check. "Refund Delivered" means the money has reached your account or the check has been mailed.

If your return shows "Return Received" for more than a few days, or if it stays in "Return Accepted" for longer than two weeks, your return may need additional review. You can contact the Missouri Department of Revenue at 573-751-3505 to ask whether your return requires manual processing or if there is a problem.

Why your refund might be delayed

The most common reasons for delays are incomplete information, math errors, or a mismatch between your return and other records the state has on file. If your name, Social Security number, or filing status does not match what the department has in its system, your return will be flagged for manual review. This can add two to four weeks to processing time.

If you claimed a refundable tax credit — such as the Earned Income Tax Credit or the Child Tax Credit — and the amount seems unusually high compared to your income, the department may review your return more carefully. This is standard practice and does not mean you did anything wrong, but it does extend the timeline.

Amended returns (Form MO-1040X) take significantly longer than original returns. Missouri typically processes amended returns within 60 days, but during busy periods it can take up to 90 days. If you need to file an amended return, do not expect your refund to arrive quickly.

Direct deposit versus paper check delivery

Choosing direct deposit when you file is the fastest way to receive your refund. The money goes straight into your bank account, and there is no risk of a check being lost in the mail. If you filed electronically and selected direct deposit, your refund should arrive within 7 to 21 days of acceptance.

If you chose a paper check, the Missouri Department of Revenue will print and mail it after your return is approved. Mailing typically takes 5 to 10 business days depending on your location within the state. Rural areas may take slightly longer. If you do not receive your check within 10 business days of the "Refund Issued" status appearing in the Where's My Refund? tool, contact the department to report it as potentially lost.

You cannot change your refund delivery method after you file. If you filed for a paper check and want direct deposit instead, you will need to wait for the check to arrive, deposit it yourself, and then request a refund correction if there is an error — which creates more delay, not less.

What to do if your refund is late

If your refund has not arrived within the expected timeframe, first check the Where's My Refund? tool to see the current status. If it shows "Refund Delivered" but you have not received the money, contact your bank to confirm the deposit did not go to a closed or incorrect account. Banks sometimes hold deposits for a day or two, especially if the account has been inactive.

If the tool shows "Refund Issued" but you have not received your check after 10 business days, call the Missouri Department of Revenue at 573-751-3505. Have your Social Security number, filing status, and the refund amount ready. The department can tell you whether the check was mailed and can issue a replacement if it appears to be lost.

If the tool shows "Return Accepted" but your refund has not been issued after 30 days, your return likely needs manual review. Call the department to ask what information they need or whether there is a problem with your filing. Do not assume the delay means a rejection — most manual reviews result in approval, just with a longer wait.

Refunds for amended returns and corrections

If you filed an amended return (Form MO-1040X) to correct an error or claim something you missed, Missouri will process it separately from your original return. Amended returns take 60 to 90 days to process, depending on the time of year and the complexity of the changes you made.

You cannot track an amended return using the standard Where's My Refund? tool. Instead, contact the Missouri Department of Revenue directly at 573-751-3505 with your Social Security number and the date you filed the amended return. The department can tell you the status and when you can expect the refund.

If the Missouri Department of Revenue owes you money from a correction or adjustment they made to your return, they will send that refund separately from your original refund. This can result in two deposits or checks arriving at different times.

Frequently Asked Questions

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

No. The Missouri Department of Revenue does not offer expedited processing for any fee. The timeline is the same for all filers. Some tax preparation companies offer refund anticipation loans, but these are loans against your expected refund, not a way to speed up the state's processing.

What if I filed my Missouri return but have not received a federal refund yet?

Missouri and federal refunds are processed separately. Your Missouri refund timeline does not depend on your federal refund, and vice versa. You can track each one independently using the respective state and federal tools.

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

If you filed a complete return with no errors, your refund will be processed and sent automatically. You do not need to take any action. If your return needs additional information or review, the Missouri Department of Revenue will contact you by mail at the address on your return.

What if my bank account information changed since I filed?

If you provided an incorrect account number or your account was closed after you filed, the direct deposit will be rejected and the department will issue a paper check instead. This adds 5 to 10 business days to delivery. Contact the department immediately if you think this happened so they can confirm the status.

Can I file my Missouri return and get my refund before April 15?

Yes. You can file your Missouri return as soon as you have all the documents you need — typically by early February. Filing early gives the department more time to process your return before the April deadline, which often means your refund arrives faster because fewer returns are in the queue.
