Call the Mississippi Department of Revenue at 601-359-1141

The Mississippi Department of Revenue handles state tax refunds. Their phone line is 601-359-1141. When you call, have your Social Security number and the amount of the refund you expect ready — the representative will need both to look up your status.

The line is open Monday through Friday, 8 a.m. to 5 p.m. Central Time. Wait times are usually shortest early in the morning or late in the afternoon. If you reach a busy signal, try again in 15 minutes rather than staying on hold.

The Department of Revenue processes refunds in the order they receive returns. If your return was filed electronically, it typically processes faster than a paper return. A representative can tell you whether your return has been received, whether it is being processed, and the expected payment date.

Key Takeaways

  • Call 601-359-1141 during business hours (Monday–Friday, 8 a.m. to 5 p.m. Central Time) with your Social Security number and expected refund amount ready.
  • Electronic returns process faster than paper returns, and the Department of Revenue processes them in the order received.
  • A representative can tell you whether your return has been received, is being processed, or has been sent for payment.
  • If you filed electronically, your refund typically arrives within 21 days of approval; paper returns take longer.
  • The Department of Revenue website also shows refund status if you prefer not to call.

What information you need before calling

Have your Social Security number available — this is the primary way the Department of Revenue looks up your account. You will also need to know the refund amount you are expecting, or at least the approximate range. If you filed jointly, either spouse's Social Security number works.

If you are calling about a business return rather than a personal return, have your Federal Employer Identification Number (EIN) instead. The representative will ask which type of return you filed, so be ready to say whether it is a 1040 (personal), 1120 (corporate), or another form.

How long refunds take after approval

Once the Department of Revenue approves your return, the timing depends on how you filed. If you filed electronically and chose direct deposit, your refund typically arrives in your bank account within 21 days. If you chose a paper check, add 7 to 10 business days for mailing.

Paper returns take longer to process overall because they must be manually entered into the system. The Department of Revenue does not publish a standard processing time for paper returns, but representatives can give you an estimate based on when yours was received.

If your refund is delayed beyond the expected window, the representative can flag your account for review. This sometimes happens if there is a discrepancy between your state and federal return, or if the address on file does not match your mailing address.

What the representative can and cannot tell you

The Department of Revenue representative can confirm that your return was received, tell you what stage of processing it is in, and give you an expected payment date. They can also update your mailing address or bank account information if needed before the refund is sent.

They cannot tell you why a refund is being held if there is a problem — they can only tell you that it is under review. If your return has been flagged, they will direct you to submit additional documents by mail or to contact the Department of Revenue in writing with an explanation.

The Department of Revenue website as an alternative

You do not have to call. The Mississippi Department of Revenue website has a refund status tool where you can enter your Social Security number and refund amount to see the same information a phone representative would give you. The tool updates daily and is available 24 hours.

The website tool is faster if you already know your refund amount and just want a quick status check. Use the phone line if you have questions about why a refund is delayed, need to update your address, or want a representative to explain next steps.

If you cannot reach the phone line

If the line is busy or you reach a recording saying the office is closed, try calling back during business hours. The Department of Revenue does not take messages on the main line, so you will need to reach a live representative.

As an alternative, you can mail a written inquiry to the Mississippi Department of Revenue, P.O. Box 540, Jackson, MS 39205. Include your name, Social Security number, and the tax year you are asking about. Responses by mail typically take two to three weeks.

Frequently Asked Questions

What if I filed my return more than a month ago and still have not heard anything?

Call 601-359-1141 and ask the representative to check whether your return is still being processed or has been flagged for review. If it has been flagged, they will tell you what documents you need to send. If it is still in the queue, they can give you a new expected date.

Can I check my refund status online instead of calling?

Yes. The Mississippi Department of Revenue website has a refund status tool that works 24 hours a day. You enter your Social Security number and refund amount, and it shows you the same information a phone representative would provide. The tool updates daily.

What if my refund was supposed to arrive by direct deposit but I have not seen it in my bank account?

Call the Department of Revenue first to confirm the refund was actually sent. If it was sent, contact your bank to ask whether the deposit is pending or if there was a problem receiving it. If the Department of Revenue has no record of sending it, ask them to check your bank account information on file.

Do I need to provide any documents when I call?

No. The representative only needs your Social Security number and the refund amount to look up your status. You do not need to have your tax return or any other paperwork in front of you, though having them nearby can help if the representative asks follow-up questions.

What if I filed a joint return — whose Social Security number do I give?

Either spouse's Social Security number works. The Department of Revenue system is linked to both names on a joint return, so you can use whichever number you have available. The representative will confirm the other spouse's name to make sure they have the right account.
