Where to check your Missouri refund status
The Missouri Department of Revenue runs a refund tracker on their website where you can see the status of your state return. Go to dor.mo.gov, find the "Refund Status" tool, and enter your Social Security number and the refund amount you expect. The tool tells you whether your return is still being processed, approved, or sent out — and if it has been sent, when.
You can also call the Missouri Department of Revenue at 573-751-4450 during business hours (Monday through Friday, 8 a.m. to 5 p.m. Central Time). Have your Social Security number and the refund amount ready. The phone line can be slow during tax season, especially in March and April, so the online tracker is usually faster.
If you filed electronically and chose direct deposit, your refund typically arrives in your bank account within 21 days of approval. If you chose a paper check, allow an additional 7 to 10 business days for mail delivery after the Department of Revenue sends it.

Why your refund might be delayed
Missouri refunds move slower during tax season (January through April) because the Department of Revenue processes thousands of returns at once. If you filed in March or early April, your refund may still be in the queue even if weeks have passed.
A refund can also be held if the Department of Revenue needs more information from you — for example, if your W-2 does not match what your employer reported, or if you claimed a credit that requires verification. The department will mail you a notice if this happens. Check your mailbox and any email address you provided on your return.
If you owe money to Missouri (back taxes, child support, or a state debt), the Department of Revenue may offset your refund to pay what you owe. This is called a refund offset. You will receive a notice in the mail explaining the offset and how much was taken.
What to do if your refund is missing or very late
If the online tracker shows your refund was approved and sent more than 21 days ago (for direct deposit) or more than 28 days ago (for a check), contact the Department of Revenue. Have your return confirmation number ready — you received this when you filed electronically, or it is on the top of your paper return if you filed by mail.
For direct deposit refunds that do not arrive on time, ask your bank to check whether the deposit was rejected. Sometimes a refund is sent but bounces back because the account number changed or the account was closed. If that happened, the Department of Revenue will mail you a check instead, which adds another 7 to 10 days.
If you filed a paper return and the tracker does not show your refund at all, your return may not have been received or processed yet. Paper returns take longer to enter the system — typically 4 to 6 weeks before they appear in the tracker. If more than 6 weeks have passed since you mailed it, contact the department to confirm they received it.
How to prevent refund problems on next year's return
File electronically instead of by mail. Electronic returns are processed faster and the Department of Revenue catches errors when ready, rather than weeks later. If you cannot file yourself, use a tax preparer or a free filing service — Missouri offers free filing through the IRS Free File program if your income is below a certain threshold.
Make sure your W-2s and 1099s match what you report on your return. If you received a W-2 from an employer but did not include it, or if the income amounts do not match, the Department of Revenue will flag your return for review. Ask your employer or the payer to send you a corrected form if there is a mistake.
Choose direct deposit instead of a paper check. Direct deposit is faster, safer (no check can be lost in the mail), and you do not have to wait for the post office.
If you need to amend your return
If you made a mistake on your Missouri return after you filed it, you can file an amended return using Form MO-1040X. You must file the amended return within three years of the original due date. read the form from dor.mo.gov or request it by calling 573-751-4450.
An amended return can increase or decrease your refund. If you are owed more money, file the amended return as soon as you notice the error. If you owe more, filing quickly can reduce any penalties or interest that might explore.

Frequently Asked Questions
Can I get my refund faster if I pay a tax preparer?
No. The Department of Revenue processes all returns at the same speed regardless of who filed them. Some tax preparers offer "refund advance" loans, but you pay interest or fees for the money, which reduces what you actually receive. It is better to wait for the real refund.
What if the tracker says my refund was sent but I never got it?
For direct deposit, contact your bank to confirm the deposit was not rejected. For a paper check, wait 10 more business days for mail delivery. If it still has not arrived, call the Department of Revenue with your return confirmation number so they can investigate whether the check was lost or sent to the wrong address.
Do I have to file a Missouri return if I only work in Missouri but live in another state?
Yes, you owe Missouri income tax on wages earned in Missouri, even if you live elsewhere. File both your home state return and a Missouri return. Some states offer credits to prevent double taxation, so check your home state's rules.
Can Missouri take my refund to pay old debts?
Yes. Missouri can offset your refund to pay back taxes, child support, student loans in default, or other state debts. You will receive a notice in the mail if this happens. Contact the agency that holds the debt to find out your options for payment or dispute.
How long does Missouri keep my tax return on file?
Missouri keeps tax returns for at least seven years. If you need a copy of an old return, contact the Department of Revenue. There may be a small fee for copies older than the current year.
