Mississippi state tax refunds arrive between late March and early June, depending on when you file and whether the Department of Revenue needs to verify your return

If you filed your Mississippi state return by early February, you can expect your refund by late March or early April. If you filed in March or April, plan for late April through May. Returns filed after mid-April may not arrive until June. The Department of Revenue processes returns in the order they arrive, not all at once, so the exact date depends on your filing date and whether your return requires manual review.

Paper returns take longer than electronic ones. A paper return filed in January might not arrive until May, while an e-filed return from the same week could come in April. If the Department of Revenue flags your return for verification—usually because of a mismatch between your W-2s and your reported income, or because you claimed a credit that needs confirmation—your refund will be delayed by two to four weeks while they investigate.

Key Takeaways

  • E-filed returns typically arrive within four to six weeks of filing; paper returns take six to eight weeks.
  • The Department of Revenue processes returns in order of receipt, so filing early in the tax season speeds up your refund.
  • You can track your refund status on the Mississippi Department of Revenue website using your Social Security number and the exact refund amount.
  • If your refund is delayed beyond the expected window, contact the Department of Revenue directly—they can tell you whether your return is under review or if there is a processing error.
  • Refunds are issued by check or direct deposit, depending on what you selected when you filed.

How to track your Mississippi refund status

Visit the Mississippi Department of Revenue website and use the "Where's My Refund?" tool. You will need your Social Security number and the exact dollar amount of your expected refund. The tool updates every few days and will tell you whether your return is still being processed, has been approved, or has been sent out.

If the tool says your refund has been issued but you have not received it, the next step depends on your delivery method. If you chose direct deposit, check your bank account—deposits can take three to five business days to appear after the Department of Revenue sends them. If you chose a check, allow up to two weeks for mail delivery. If more than two weeks have passed since the tool said your refund was issued and you still have not received it, call the Department of Revenue at 601-359-1141.

Direct deposit versus check delivery

Direct deposit is faster and more reliable. If you chose direct deposit when you filed, your refund will land in your bank account within three to five business days of the Department of Revenue releasing it. The tool will show the date the refund was issued, and you can count forward from there.

A check takes longer. The Department of Revenue prints and mails checks in batches, so even after your return is approved, there is a delay of several days before your check is printed and another week to two weeks for postal delivery. If you filed by paper and chose a check, add an extra week to the timeline because paper returns themselves take longer to process.

If you are expecting a check and want to change to direct deposit for next year, you will need to file electronically and provide your bank account information when you file. You cannot change the delivery method for a refund that has already been issued.

Why your refund might be delayed

The most common reason for a delay is a mismatch between your W-2s and your tax return. If your employer reported different income than what you claimed, or if you reported income that does not match a W-2 on file, the Department of Revenue will hold your return for verification. This usually adds two to four weeks to the timeline.

A second common reason is claiming a credit that requires proof. The Earned Income Tax Credit, the Child and Dependent Care Credit, and education credits all require supporting documentation. If you did not include the right forms or if the Department of Revenue wants to double-check your claim, they will delay your refund until they receive what they need or until they finish their review.

Errors on your return—a wrong Social Security number, a missing signature on a paper return, or math mistakes—will also trigger a delay. The Department of Revenue will contact you if they find an error, but this can take several weeks. If you know you made a mistake after you filed, you can file an amended return (Form 1040-X for federal, or the Mississippi equivalent), but this will delay your original refund further.

What to do if your refund does not arrive on time

First, check the "Where's My Refund?" tool again. If it still shows your return is being processed, wait another week and check again. If it shows your refund was issued more than two weeks ago and you have not received it, contact the Department of Revenue.

Call 601-359-1141 during business hours (Monday through Friday, 8 a.m. to 5 p.m. Central Time). Have your Social Security number, filing status, and the exact refund amount ready. The Department of Revenue can tell you whether your check was mailed, whether there was a problem with your direct deposit, or whether your return is still under review. If your check was lost in the mail, they can issue a replacement. If your direct deposit failed because of a closed account or incorrect routing number, they can reissue it to a corrected account.

If you filed by paper and your refund is more than eight weeks late, or if you filed electronically and your refund is more than six weeks late, call immediately. At that point, something has likely gone wrong in processing, and the Department of Revenue can investigate.

Amended returns and refund delays

If you filed your original return and then realized you made a mistake, you can file an amended return. However, this will delay your refund. The Department of Revenue processes amended returns after original returns, so even if your original return was approved, filing an amended return puts you back in the queue.

Only file an amended return if the mistake actually changes your refund amount or your tax liability. Small errors that do not affect the bottom line are not worth the delay. If you do file an amended return, use Form 1040-X (federal) or the Mississippi equivalent, and mail it to the Department of Revenue. Amended returns cannot be filed electronically in Mississippi, so expect an additional two to four weeks of processing time on top of the original timeline.

Refunds offset by state debt

If you owe money to the state of Mississippi—back child support, unpaid student loans, or other state debts—the Department of Revenue can hold your refund to pay down that debt. This is called a refund offset. If this happens, the Department of Revenue will send you a notice explaining what debt was offset and how much was taken.

If you believe the offset was made in error, or if you have questions about the debt, contact the agency that holds the debt (the Department of Human Services for child support, the state student loan servicer for education debt, and so on). The Department of Revenue cannot reverse an offset on their own; the original creditor has to request it.

Frequently Asked Questions

Can I get my refund faster if I file electronically?

Yes. E-filed returns are processed in about four to six weeks if there are no issues, while paper returns take six to eight weeks. E-filing also reduces the chance of errors that trigger delays, since the software catches many common mistakes before you submit.

What if the "Where's My Refund?" tool says my return is still being processed after six weeks?

Your return is likely under review. Call the Department of Revenue at 601-359-1141 to find out why. Common reasons include a mismatch with your W-2, a credit that needs verification, or an error on your return that they are investigating.

If I file my return in May, when should I expect my refund?

A May filing will typically result in a refund by late June or early July, assuming no issues arise. Paper returns filed in May may not arrive until July. The later you file, the longer you wait, because the Department of Revenue processes returns in order.

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

No. Once you file, your delivery method is locked in. You can only change it for next year's return. If you filed for a check and want the money faster, your only option is to wait for the check to arrive.

What happens if my direct deposit fails because my bank account is closed?

The Department of Revenue will attempt the deposit, it will be rejected, and they will hold the refund. Call them at 601-359-1141 with a new bank account number, and they can reissue the refund to the correct account. This adds about a week to your timeline.
