Check your refund status through the Montana Department of Revenue website

The Montana Department of Revenue runs a tool called Where's My Refund that tells you whether your state tax return has been processed and when your refund will arrive. You can use it on the Department of Revenue website without logging in — you only need your Social Security number, filing status, and the exact refund amount you expect.

The tool updates every business day and shows you one of four statuses: your return is still being processed, your refund has been approved and a payment date has been set, your refund was sent on a specific date, or there is a problem with your return that needs attention. If your refund was sent by mail, the tool will tell you the date it was mailed. If it was sent by direct deposit, the tool will show the date the money should have hit your bank account.

You can check as often as you want — checking multiple times does not slow down processing. Most returns are processed within 21 days of the Department of Revenue receiving them, though returns with errors or missing information take longer.

Key Takeaways

  • The Montana Department of Revenue's Where's My Refund tool is free and requires only your Social Security number, filing status, and expected refund amount.
  • The tool updates every business day and shows whether your return is being processed, approved, sent, or flagged for a problem.
  • Most refunds arrive within 21 days of the Department of Revenue receiving your return, though incomplete returns take longer.
  • If the tool shows a problem with your return, the Department of Revenue will contact you by mail with instructions on what to fix.
  • Refunds sent by direct deposit usually arrive within one business day of the date shown in the tool; mailed refunds take 7 to 10 business days after the mailing date.

What to do if the tool says there is a problem

If Where's My Refund shows that your return has an error or is missing information, the Department of Revenue will send you a letter explaining what needs to be fixed. Read the letter carefully — it will tell you exactly what documents or information they need and where to send them. Do not ignore the letter, because your refund will not be processed until the problem is resolved.

Common problems include a mismatch between the name or Social Security number on your return and what the Department of Revenue has on file, missing or illegible information on the form itself, or a discrepancy between what you reported and what your employer or bank reported to the state. If you are unsure what the letter is asking for, you can call the Department of Revenue's tax information line at 406-444-6900 during business hours.

How long refunds take after approval

Once the Department of Revenue approves your refund, the time it takes to reach you depends on how you chose to receive it. If you asked for direct deposit to your bank account, the money should arrive within one business day of the approval date shown in Where's My Refund. If you chose to receive a paper check by mail, allow 7 to 10 business days after the mailing date for the check to arrive, depending on where you live in Montana and mail delivery speed.

If your refund was approved more than 10 business days ago and you have not received it, check Where's My Refund again to confirm the status. If the tool still shows it was sent but you have not received it, contact the Department of Revenue to report the missing refund.

What to do if you cannot find your return in the system

If Where's My Refund does not show any record of your return, it may not have been received yet. If you mailed a paper return, allow at least two weeks from the date you mailed it before checking. If you filed electronically, the Department of Revenue should have received it within 24 hours.

If two weeks have passed since you mailed your return or 24 hours since you filed electronically and the tool still shows nothing, your return may have been lost in the mail or there may be a filing error. Contact the Department of Revenue at 406-444-6900 to confirm whether they received your return. Have your Social Security number, filing status, and the date you filed ready when you call.

Refunds and tax credits you may not know about

Montana offers several tax credits that reduce the amount of tax you owe and can result in a refund even if no tax was taken from your paycheck. The Montana Earned Income Tax Credit is available to working people with lower incomes and can be worth several hundred dollars. The Property Tax Reduction Credit helps renters and homeowners with property tax or rent burden, and the Dependent and Disabled Dependent Credit provides money back for dependents.

These credits are only added to your refund if you report them on your tax return. If you did not claim them when you filed, you may be able to file an amended return to add them. An amended return takes longer to process than an original return — usually 30 to 45 days — but can result in a larger refund. You can file an amended return up to three years after the original filing important date.

Direct deposit versus mailed checks

Choosing direct deposit when you file your return gets your refund to you faster and more reliably than a mailed check. Direct deposit refunds usually arrive within one business day of approval. Mailed checks take 7 to 10 business days and can be delayed by mail delivery problems, address changes, or checks that are lost or damaged in transit.

If you filed by mail and did not request direct deposit, your refund will be sent by check. If you want to switch to direct deposit for future years, you can request it when you file next year's return. Some tax preparation services also offer a refund advance — they give you the money when ready and collect it from your refund when it arrives — but this service usually costs a fee.

Frequently Asked Questions

How do I know if my refund was lost in the mail?

Check Where's My Refund to see the date your check was mailed. If more than 10 business days have passed since that date and you have not received it, contact the Department of Revenue at 406-444-6900. They can issue a replacement check or arrange direct deposit of the refund amount to your bank account instead.

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

No. Calling does not speed up processing. The Department of Revenue processes returns in the order they are received, and the Where's My Refund tool shows you the same information their staff would tell you. Calling is useful only if the tool shows a problem with your return or if your refund has been missing for longer than expected.

What if I filed my Montana return but I also filed a federal return?

Montana and federal refunds are processed separately and on different timelines. Your Montana refund status appears only in Where's My Refund. Your federal refund status appears in the IRS's Where's My Refund tool on the IRS website. One refund being delayed does not affect the other.

Do I need to do anything if Where's My Refund shows my refund was sent?

No. Once the tool shows your refund was sent, it will arrive on its own. If you chose direct deposit, watch for it to appear in your bank account. If you chose a mailed check, watch your mail. You do not need to contact the Department of Revenue unless the refund does not arrive within the expected timeframe.

Can I change my refund to direct deposit if I already filed?

No. Once you file your return, you cannot change how the refund is sent. If you filed by mail and requested a check, your refund will come by check. You can request direct deposit when you file next year's return, or you can deposit a mailed check into your bank account yourself.
