Income Tax Deadline Extended for Montana
Governor Greg Gianforte extended the payment and filing deadlines for Montana individual income taxpayers’ 2020 tax returns to May 17, 2021.
“Last year brought real, serious challenges to Montanans, and it’s only appropriate to extend the deadline so Montana taxpayers have some extra time to file, without having to worry about interest or penalties,” Governor Gianforte said.
The May 17 deadline is in keeping with the new federal filing deadline.
The Department of Revenue advises that the American Rescue Plan Act excludes the first $10,200 of unemployment benefits from federal taxes for those making less than $150,000. Those who have already filed their federal and Montana tax returns do not have to amend their returns. But those who received unemployment benefits in 2020 and have not yet filed should follow the revised instructions for their Montana return at MTRevenue.gov.
