Where to check your Missouri tax refund

Missouri's Department of Revenue runs a tool called Where's My Refund? on their website. You go to the Missouri Department of Revenue homepage, find the tax section, and look for the refund tracker. It tells you whether your return has been received, is being processed, or has been sent out.

The tool works only after the state has received and begun processing your return. If you filed very recently — within a few days — the system may not show your information yet. The state typically takes 21 days to process a return once it arrives, though some take longer if they need more information from you.

You can also call the Missouri Department of Revenue directly at their tax information line. They can look up your refund status by phone if you have your Social Security number and the amount you expect to receive. The phone line is available during business hours on weekdays.

Key Takeaways

  • Missouri's Where's My Refund? tool on the Department of Revenue website shows whether your return has been received and when your refund was sent.
  • The tool works only after the state receives your return, which can take a few days if you filed electronically or longer if you mailed it.
  • Processing normally takes 21 days, but returns that need additional information may take longer.
  • You can call the Missouri Department of Revenue tax line during business hours if you prefer to check by phone instead of online.
  • If your refund was sent by direct deposit, it appears in your bank account within one to three business days after the state releases it.

What information you need to check your refund

To use Where's My Refund?, have your Social Security number ready and know the amount you expect to receive. The amount should match what you calculated on your tax return — the refund total before any offsets or adjustments. If you are checking for a joint return, you can use either spouse's Social Security number.

If you are calling instead of using the online tool, the same information applies. The tax line representative will ask for your Social Security number and the refund amount to pull up your account. Having both pieces of information ready makes the call faster.

How long Missouri takes to process refunds

The standard timeframe is 21 days from the date the state receives your return. If you filed electronically, the state usually receives it within a day or two. If you mailed a paper return, allow extra time for postal delivery — typically five to ten business days — before the 21-day processing clock starts.

Some returns take longer. If the state needs to verify information on your return, ask questions about deductions, or match your return against other records, processing can extend to 30, 45, or even 60 days. The Where's My Refund? tool will show a message if your return is under review or needs additional information.

Once the state approves your refund and releases it, the delivery method determines when you receive the money. Direct deposit refunds arrive in your bank account within one to three business days. Paper checks take longer — typically five to ten business days after the state mails them, depending on postal service.

What to do if your refund is delayed

Check the Where's My Refund? tool first to see whether the state has flagged your return for review. If the tool shows a message about additional information needed, read it carefully — it will tell you what documents or clarification the state is waiting for. Some returns need you to send in supporting documents like receipts or proof of income.

If the tool shows no message but your refund is past the 21-day window, call the Missouri Department of Revenue tax line. Have your return in front of you so you can answer questions about what you reported. The representative can see notes in your account that the online tool does not display.

If the state withheld part of your refund to cover other debts — such as unpaid child support, student loans, or back taxes — the Where's My Refund? tool or a phone representative will tell you. These offsets are legal holds and cannot be reversed through the tax department; you would need to address the underlying debt.

Direct deposit versus paper check refunds

Missouri offers both methods. Direct deposit is faster and more reliable — your money arrives in your bank account within one to three business days after the state releases it. Paper checks are mailed by the state and take five to ten business days to arrive after mailing, plus any postal delays.

If you chose direct deposit on your return, make sure the bank account and routing number you entered are correct. If you made a mistake, contact the Missouri Department of Revenue as soon as you realize it. The state may be able to correct the information before the refund is released, but once it is sent to a wrong account, recovering it is difficult and slow.

If you chose a paper check and want to change to direct deposit for next year, you can do that when you file your next return. There is no way to change the delivery method for a refund that has already been processed.

When to contact the Missouri Department of Revenue

Contact the tax line if your refund is more than 21 days past the date you filed, if the Where's My Refund? tool shows an error or confusing message, or if you think the state has the wrong bank account information. You can also call if you received a notice from the state about your return and do not understand what it says.

Have your return, your Social Security number, and any notices from the state in front of you when you call. The representative will need to verify your identity before discussing your account. If you filed a joint return, either spouse can call, but you will need to provide both Social Security numbers.

The Missouri Department of Revenue tax information line is open Monday through Friday during regular business hours. Call times are typically shorter early in the morning or late in the afternoon. During tax season (January through April), wait times are longer.

Understanding refund offset and debt collection

If you owe money to the state or federal government — such as back taxes, unpaid child support, or defaulted student loans — the state may withhold part or all of your refund to pay that debt. This is called an offset. The Where's My Refund? tool will show if an offset has been applied.

If your refund was offset, the state will send you a notice explaining what debt was collected and how much was taken. You cannot reverse an offset through the tax department. To dispute it, you would need to address the underlying debt directly — for example, by contacting the child support agency or the student loan servicer.

Some debts can be challenged. If you believe the offset was made in error or the debt has been paid, contact the agency that holds the debt, not the tax department. They can work with the state to correct the record.

Frequently Asked Questions

How do I know if my return was received by Missouri?

The Where's My Refund? tool will show "Return Received" once the state has it in their system. If you filed electronically, this usually happens within one or two days. If you mailed a paper return, allow five to ten business days for postal delivery before checking.

Can I check my refund status if I filed a joint return?

Yes. Use either spouse's Social Security number and the total refund amount from the return. The state processes joint returns under both names, so either person can look up the status online or by phone.

What does it mean if the tool says my return is under review?

The state is verifying information on your return — checking deductions, income, or credits against other records. This adds time to processing. The tool or a notice from the state will tell you if you need to send documents. Do not wait; send what they ask for as soon as you can.

My refund was supposed to arrive by direct deposit but I have not seen it. What do I do?

First, check your bank account to make sure it did not arrive under a different date or description. If it is not there after three business days from when the state released it, call your bank to confirm they have the correct routing and account number. Then call the Missouri Department of Revenue to verify they sent it to the right account.

Can I change my refund from a paper check to direct deposit?

No, not after the return has been processed. Once the state has approved your refund, the delivery method is locked in. You can choose direct deposit on your next year's return to speed up future refunds.
