Montana Dept. Of Revenue: If You Move, Let Us Know
April 21, 2021 | View PDF
The Montana Department of Revenue has an important message to Montana taxpayers who move after filing their income tax return: Keep your mailing address current with the department.
This is especially true for anyone filing a Montana income tax return for the first time. The department sends refunds to first-time filers only by paper check – not by direct deposit – due to our security measures to combat fraud.
Taxpayers who haven’t filed a Montana return since 2018 will also receive any refund by paper check.
This means your refund will be delayed if the department has an incorrect address.
Also, the department may try to contact you by mail if there are questions about your filing or if we need more information from you.
You can download a change-of-address form at MTRevenue.gov or request one from our Call Center at 406- 444-6900.
In 2020, more than 4,800 state income tax refund checks were returned to the department because of incorrect addresses. Affected taxpayers included college students, seasonal workers, part-time Montana residents, and others who moved after filing.
The Department of Revenue also reminds taxpayers:
• Electronic filing is the safest and fastest way to file your return and get your refund as quickly as possible.
• It could take up to 90 days to process refunds for some taxpayers due to security measures taken against identity theft and fraud. Taxpayers can check the status of their refund at MTRevenue.gov.
• For those who worked remotely in Montana during any part of 2020, income earned while working in the state is taxable in Montana.
Montana and federal 2020 individual income tax returns are due May 17.
