Whether you are buying your first or fifth property purchase in Montana, how property taxes are assessed and paid is often a source of confusion for buyers.
The basics:
The Dept. of Revenue has a field office in each county responsible for valuing all property except centrally assessed and large industrial properties.
Properties are assessed on a two-year cycle by the state, and do not increase automatically based on the purchase price, which is how many other states assess their taxes.
Property taxes are based on 3 components:
1. The value of the property
2. The tax rate on the property
3. The number of mills applied to the property*
The median property tax in Montana is $1,465.00 per year for a home worth the median value of $176,300.00. Counties in Montana collect an average of 0.83% of a property's assesed fair market value as property tax per year.
