Montana Tax Facts

MT Income Tax:

Individual income is taxed across seven tax brackets at seven graduated tax rates.

1% for the first $2,800 of taxable income
2% for taxable incomes between $2,800 and $5,000
3% for taxable incomes between $5,000 and $7,600
4% for taxable incomes between $7,600 and $10,300
5% for taxable incomes between $10,300 and $13,300
6% for taxable incomes between $13,300 and $17,100
6.9% on taxable incomes $17,101 and above

MT Sales Tax:

Though Montana does not have a sales tax at the state nor local level, some communities have resort and local option taxes as their funding source. The purpose for these taxes is to allow places with high numbers of visitors, but relatively few residents, to collect local infrastructure costs without overburdening local citizens. The maximum rate of the resort tax is 3%. At least 5% of collected revenue must offset property taxes.

MT Personal Property Tax:

The Property Assessment Division of the Montana Department of Revenue is responsible for administering the state's property tax laws. This includes the assessment and valuation of personal and real property throughout the state.

Though household goods are exempt from personal property taxes, farm machinery, automobiles, business equipment, heavy equipment, and trucks are not. The Department of Revenue also collects a per capita fee on livestock.

The amount of property tax owed is not mainly determined by the value of the property. The property of the value is multiplied by a tax rate, which is set by the Montana Legislature, to determine its taxable value. The taxable value is then multiplied by the mill levy established by various taxing jurisdictions, such as county governments, city governments, and school districts.

If Montana property owners meet certain qualifications, they can have their property taxes reduced.

Odd Tax Fact:

Montana's Medical Marijuana Act greatly affects state income taxes.

Qualifying patients are not entitled to a deduction on their tax return for the cost of growing or purchasing marijuana, even if they own a valid medical marijuana card that allow them to grow or possess the drug for medical purposes.

The only drugs that are allowed as an itemized deduction for medical expenses are those that a physician prescribes (insulin being the exception). Federal law prohibits a physician from prescribing marijuana, even in states where medical marijuana is legal. Therefore, under the MT Medical Marijuana Act, physicians do not prescribe the drug, but only certify the qualifying patient for it.
