Montana Reduces the Highest Tax Rate for Individuals, Trusts, Estates, and Partnerships for 2022
The Montana legislature recently passed Senate Bill 159, which reduced the highest marginal tax rate for individuals, estates, trusts, and pass-through entities beginning with the 2022 tax year. The highest marginal tax rate will be reduced to 6.75% (from 6.9%) on taxable income over $17,400. Montana has seven marginal tax rates, and the passage of this bill does not affect the six lower marginal tax rates. After the 2022 tax year, the bill is subject to the ARPA Savings Clause, and the rate can revert to 6.9% if the savings clause is triggered.

If enacted, the new apportionment formula would be effective for tax years beginning after June 30, 2021.

The Montana Department of Revenue has announced that Montana Governor Greg Gianforte has extended the filing and payment deadlines for 2020 Montana individual income tax returns to May 17, 2021. The governor explained that it was appropriate to extend the deadline without having taxpayers worry about interest and penalties, and the new May 17, 2021 deadline follows the new federal filing deadline of May 17, 2021 which was announced on March 17, 2021. The Department also noted that quarterly estimated payment deadlines for 2021 income taxes have not changed. ( Governor Gianforte Extends Tax Filing Deadline to May 17, Mont. Dept. Rev., 03/18/2021.)
