Call the Michigan Department of Treasury if you filed a state return

The Michigan Department of Treasury handles all state income tax refunds. Their phone line is 517-636-4486. Have your Social Security number and the tax year in question ready when you call. They can tell you whether a refund was issued, when it was sent, and what method it used (check, direct deposit, or debit card).

The department's hours are Monday through Friday, 8 a.m. to 4:30 p.m. Eastern time. Wait times are often longest in March and April, so calling in the afternoon or on Thursday or Friday may be faster. If you cannot reach them by phone, you can also file a question through their online portal at michigan.gov/taxes, though responses take longer than a phone call.

If you filed jointly with a spouse, either of you can call on behalf of the refund. You will need to provide the name and Social Security number of the person whose refund status you are checking.

How to check your refund status before calling

Michigan offers an online refund tracker on their website. Go to michigan.gov/taxes, select "Individuals," then look for "Refund Status" or "Where's My Refund." You will need your Social Security number, filing status (single, married, etc.), and the exact refund amount from your return. This tool updates daily and can answer your question without a phone call.

The online tracker shows whether your refund has been processed, issued, and delivered. If it shows "issued," the refund has left the state's control and is in the mail or in your bank account. If it shows "pending," the state is still processing your return. Processing times vary depending on whether you filed electronically or by mail, and whether the return required additional review.

If the online tool does not show your refund at all, or if the amount shown does not match what you expected, that is when to call the department. They can see details the public tool cannot, including whether your return is under review or whether there is a hold on the refund.

Refund timing and delivery methods

Michigan processes most electronic returns within 21 days of receipt. Paper returns take longer—typically four to six weeks. The state then issues the refund by the method you chose on your return: direct deposit (fastest, usually five to seven business days after processing), check (mailed within two weeks of processing), or a debit card (issued within two weeks of processing).

If you chose direct deposit, the money goes into the bank account you listed on your return. If you chose a check, it is mailed to the address on file. If you chose a debit card, the card is mailed to you and you can use it immediately once it arrives. The state does not control delivery time for checks or cards after they leave the treasury office, so mail delays can add one to two weeks.

If your refund was issued more than two weeks ago and you have not received it, call the department. They can confirm the delivery method and, if it was mailed, may be able to issue a replacement check or investigate a missing card.

What to do if your refund is delayed or missing

If the online tracker shows your refund as "issued" but you have not received it after the expected timeframe, call 517-636-4486 and ask the department to investigate. Provide the date the refund was issued and the delivery method. The department can check whether the check was cashed, whether the direct deposit went through, or whether the card was activated.

If a check was lost in the mail, the department can issue a replacement. If direct deposit failed, they can reissue the refund to a different bank account or by check. If a debit card was never received, they can cancel it and reissue a new one or send a check instead. These replacements usually take two to four weeks.

If your return is still showing as "pending" after the expected processing time, the department may be reviewing your return for errors or requesting additional documentation. Call to ask whether they need anything from you. Some returns require proof of income, residency, or dependent information before the refund can be released.

Refunds held for unpaid debts or child support

Michigan can hold a refund if you owe back taxes, child support, or other state debts. The online tracker will not show a refund amount if a hold is in place—it will show "pending" indefinitely. When you call the department, they will tell you whether a hold exists and which agency placed it.

If the hold is for unpaid Michigan taxes from a prior year, the department will apply your refund to that debt and send you a notice. If the hold is for child support or another state debt, you will need to contact the agency that placed the hold to resolve it. The department cannot release the refund until the hold is lifted.

If you believe a hold was placed in error, ask the department which agency to contact. They can provide a phone number or direct you to the right office to dispute the hold.

Federal refunds versus Michigan state refunds

If you are waiting for both a federal and a Michigan state refund, they are handled by completely separate systems. The IRS processes federal returns and issues federal refunds. Michigan processes state returns and issues state refunds. Calling the Michigan Department of Treasury will not give you information about your federal refund, and vice versa.

Federal refunds can be tracked at irs.gov using the IRS "Where's My Refund" tool. State refunds are tracked at michigan.gov/taxes. The two refunds may arrive at different times even if you filed both returns on the same day. A federal refund can take 21 days or longer, while a Michigan state refund typically takes 21 days for electronic returns.

If you filed a joint federal return with a spouse but separate Michigan returns, or vice versa, the refunds will be issued separately to each person. Make sure you are checking the correct refund status for the correct person and the correct tax year.

Frequently Asked Questions

Can I get my Michigan refund faster if I call instead of checking online?

No. Calling the department does not speed up processing or delivery. The phone line can only tell you the current status. If your refund is still being processed, it will be ready when it is ready. If it has already been issued, calling will not make it arrive faster.

What if I moved and the check was sent to my old address?

Call the department and provide your new address. If the check has not been cashed, they can issue a replacement to your new address. If the check was cashed by someone else, report it to the department and ask about next steps. You may need to file a police report for fraud.

Do I need to provide my PIN or password when I call?

No. The department will ask for your Social Security number and other identifying information, but they will not ask for passwords or PINs. If someone claiming to be from the treasury asks for a password or PIN, hang up—it is a scam.

How long does it take to get a replacement check if mine was lost?

The department typically issues a replacement check within two to four weeks of your request. The check is then mailed to you, which adds one to two weeks depending on mail delivery. In total, expect four to six weeks from the time you call to request a replacement.

Can I change my refund delivery method after I filed?

No. Once you file your return, the delivery method is locked in. If you chose a check but now want direct deposit, you cannot change it for that year's refund. You can only choose your preferred method when you file next year's return.
