Missouri refunds take longer when the state revenue department is processing a high volume, your return has errors, or you chose mail delivery instead of direct deposit

Missouri's Department of Revenue processes tax returns in the order they arrive, not all at once. If you filed early in the season, your return may still be in the queue. If you filed closer to the deadline or amended your return, expect a longer wait. The state also flags returns for manual review when something doesn't match their records — a Social Security number mismatch, income that doesn't align with W-2s you filed, or a claim they need to verify.

The delivery method matters too. Direct deposit refunds arrive in your bank account in 5 to 10 business days once the state approves your return. Paper checks take 2 to 3 weeks after approval, and that clock starts only after the state has finished reviewing your return. If you chose mail delivery, you are waiting for processing time plus postal time.

Missouri does not have a published average processing time the way some states do. The Department of Revenue's website says refunds "typically" arrive within 30 days of filing, but that is a ceiling, not a promise. During tax season (January through April), the department processes thousands of returns daily. If your return arrived in March, it may still be in the queue in May.

Key Takeaways

  • Direct deposit refunds arrive 5 to 10 business days after the state approves your return; paper checks take 2 to 3 weeks after approval.
  • Missouri's Department of Revenue flags returns for manual review when income doesn't match W-2s, Social Security numbers don't align, or claims need verification — this adds weeks to processing time.
  • You can check your refund status on the Missouri Department of Revenue website using your Social Security number and filing status, and the tool updates every 24 hours.
  • If your return has been pending for more than 60 days and the status tool shows no progress, contact the Department of Revenue directly by phone or through their online form.

How to check your Missouri refund status right now

The Missouri Department of Revenue runs a refund status tool on its website. Go to dor.mo.gov, find the "Where's My Refund?" link, and enter your Social Security number, filing status (single, married filing jointly, etc.), and the exact refund amount you expect. The tool updates once every 24 hours, so checking multiple times in one day will not show new information.

The status tool will tell you one of four things: your return is still being processed, your return has been approved and your refund is on the way, your refund has been issued, or there is a problem with your return that needs attention. If the tool says your return is still being processed after 60 days, that usually means it is in the manual review queue.

Write down the date you checked and what the status said. If you check again in a week and nothing has changed, that is a sign you should contact the department directly.

Why Missouri holds returns for manual review

The state's computer system automatically flags certain returns for a person to look at by hand. This happens when your W-2 income does not match what you reported, when you claim a dependent the state's records do not show, when you claim a large refund relative to your income, or when your Social Security number does not match the name on file. It also happens if you amended a return you filed in a previous year.

Manual review is not a sign you did something wrong. It is a verification step. A person at the Department of Revenue will compare your return to your W-2s, your prior-year return, and any other documents on file. This takes 2 to 4 weeks on average, though it can take longer if the department is backlogged or if they need to contact your employer to confirm information.

You cannot speed up manual review by calling or emailing. The department will contact you if they need more information from you. If they do contact you, respond as quickly as you can — delays in your response delay your refund.

What to do if your refund status has not changed in 60 days

Log into the "Where's My Refund?" tool again and note the exact status message. Then contact the Missouri Department of Revenue. You can call their individual income tax line at 573-751-3505, Monday through Friday, 7:30 a.m. to 5 p.m. central time. Have your Social Security number, filing status, and the refund amount ready when you call.

If you prefer not to call, you can submit a question through the Department of Revenue's online form at dor.mo.gov. Click "Contact Us," select "Individual Income Tax," and describe your situation. Include your Social Security number, the date you filed, and the status message from the refund tool. The department typically responds to online inquiries within 5 to 7 business days.

When you contact them, ask three things: whether your return is still in the processing queue, whether it has been flagged for manual review, and if so, what information they are waiting for. If they are waiting for something from you, ask what document they need and how to send it. If they are waiting for something from your employer, ask how long that usually takes.

Reasons your Missouri refund might be delayed beyond normal processing time

If you amended a return you filed in a prior year, Missouri processes the amended return separately from your current-year return. Amended returns take longer because the department has to compare your new information to what you originally reported and make sure the change is correct. This can add 4 to 8 weeks to your refund timeline.

If you claimed the Earned Income Tax Credit (EITC) or the Child and Dependent Care Credit, the IRS requires Missouri to hold your refund for additional verification. This is a federal requirement, not a Missouri choice. The hold typically lasts 21 days from the date you filed, but can extend longer if the IRS needs to verify your may be able to access. You will see a note on the refund status tool if this applies to you.

If you owe back taxes, child support, or student loans, Missouri may offset your refund to pay down what you owe. The state will notify you in writing if this happens. Your refund will be reduced by the amount of the offset, and the remainder (if any) will be sent to you. This process adds 2 to 4 weeks to your timeline.

If you filed a paper return instead of filing online, processing takes longer. Paper returns have to be scanned and entered into the system by hand, which adds 1 to 2 weeks to the timeline before your return even enters the processing queue.

Direct deposit versus paper check: which one arrives faster

Direct deposit is faster. Once the Department of Revenue approves your return, they send the refund to your bank electronically. Your bank receives it within 1 to 2 business days and posts it to your account within 5 to 10 business days total. The exact timing depends on your bank's processing speed, but most banks post tax refunds within 3 to 5 business days of receiving them.

Paper checks are slower. After the state approves your return, they print the check, which takes 3 to 5 business days. Then the check goes into the mail. Depending on where you live in Missouri and where the check is mailed from, postal delivery takes 5 to 10 business days. Total time from approval to arrival at your mailbox is usually 2 to 3 weeks.

If you filed for direct deposit and your bank account information was incorrect, the refund will be rejected and the state will issue a paper check instead. This adds 2 to 3 weeks to your timeline. You will receive a notice in the mail telling you the direct deposit failed.

What to do if you think there is an error on your return

If you realize you made a mistake on your return after you filed it, do not file an amended return right away. Wait until the Department of Revenue has processed your original return and issued your refund. Once you receive the refund, you can file an amended return (Form MO-1040-X) if the error results in you owing more tax. If the error means you should have received a larger refund, filing an amended return will get you the difference.

Amended returns take longer to process than original returns, so only file one if the error actually changes the amount of tax you owe or the refund you should receive. Small errors that do not affect the dollar amount do not require an amended return.

If you think the Department of Revenue made an error — for example, they applied your refund to a debt you do not owe — contact them immediately. Call 573-751-3505 or submit an online inquiry. Explain what you believe the error is and ask them to review it. If they made a mistake, they will correct it and reissue your refund.

Frequently Asked Questions

Can I get my Missouri refund faster if I call the Department of Revenue?

No. Calling does not move your return to the front of the queue. The department processes returns in the order they were filed. If your return is in manual review, calling will not speed that up either. The only reason to call is if your return has been pending for more than 60 days with no status change, or if you believe there is an error.

What does it mean if the refund status tool says "return received"?

It means the Department of Revenue has scanned your return into their system and it is waiting to be processed. This is the first step. Your return will move to "being processed" once a computer system begins reviewing it for errors. This can take several days to several weeks depending on volume.

If I filed my Missouri return late, will my refund be delayed?

Filing after the April 15 deadline does not delay your refund once the state receives it. However, you may owe a late-filing penalty if you owe tax. The Department of Revenue will calculate the penalty and subtract it from your refund. This does not add processing time — the penalty is simply deducted from what you receive.

Can I get my refund by direct deposit if I already chose a paper check?

No. Once you file your return, you cannot change the refund delivery method. If you chose a paper check and now want direct deposit, you will have to wait for the paper check to arrive, then file an amended return requesting direct deposit for any additional refund. This is not worth doing unless the error on your original return results in a larger refund.

What happens if my refund status shows "issued" but I have not received it yet?

If the status says "issued" and you chose direct deposit, check your bank account — it may have posted without a notification. If you chose a paper check, it is in the mail. Paper checks typically arrive within 10 business days of the "issued" status. If more than 10 business days have passed and you have not received it, contact the Department of Revenue and ask them to trace the check.
