Montana State Taxes Explained

Montana Sales Tax

Montana has no state sales tax, although local taxes apply in some resort areas, such as Big Sky, Red Lodge, and Yellowstone.

Montana Income Taxes

Montana’s higher income tax brackets kick in at a relatively low threshold, which can mean a heavier tax burden on many residents. But there will be only two tax rates beginning in 2024: 4.7% for up to $20,500 of taxable income for single filers ($41,000 for married couples filing jointly) and 6.5% for all others.

Montana Property Taxes

Montana’s effective property tax rate is 0.84%. Homeowners pay $1,928 on the average $230,600 home value. Properties are assessed at 100% market value. Local governments may impose additional taxes.

Montana’s Property Tax Assistance Program (PTAP) reduces the property tax rate for citizens on a fixed or limited income. The PTAP benefit applies to the first $200,000 of the primary residence market value. Reductions from 30% to 80% are determined by marriage status and income range. For disabled veterans and surviving spouses, property tax reductions range from 50% to 100%, depending on income level and marital status via the Montana Disabled Veterans (MDV) Assistance Program.

Homeowners and renters age 62 or older can apply for an income tax credit if they’ve lived in Montana for nine months, rented, owned or leased a home in Montana for six months, and have a total household income of less than $45,000.

Visit Montana’s tax relief page for information about all available property tax assistance.

Montana Retirement Taxes

Montana taxes all pension, Social Security, and military retirement income.

Some Montana retirees are entitled to a partial exemption from a retirement plan income, including from 401(k) plans and IRAs. Taxpayers must have a federal adjusted gross income of $40,980 or less ($43,300 or less for joint filers). Married spouses can each claim the exemption. Interest income is partially exempt from Montana tax for taxpayers age 65 or older. The exemption is up to $800 for single filers and $1,600 for joint filers.

Retired military income is taxed at the federal amount.
