Montana State Income Tax 2024 - 2025

Montana has a progressive state income tax system, with rates of 1% to 6.75% on taxable income.

The state of Montana requires employers to withhold and remit state income tax on wages paid to employees. This is in addition to the federal withholding taxes that must be deducted. In order to make payments, Montana employers must register with the Department of Revenue and the Department of Labor and Industry. The Department of Revenue collects personal and business taxes, such as individual income tax, corporate income tax, mineral royalty withholding, and alcoholic beverage tax. It also administers the cigarette excise tax and oversees property assessment and appraisal. The state is one of the few that does not levy a local sales tax. Individuals who work in Montana are subject to a state income tax rate that varies by bracket. The rate ranges from 1% to 6.75%, depending on the taxable income.

When you file a Montana state return, the department requires that you pay any taxes owed by the original due date of your return (April 15th for calendar year filers). If you do not pay the tax by the due date, the department may levy (seize) your wages or bank accounts. If you are having trouble paying your taxes, contact a local tax pro for help.
