To calculate the exact amount of property tax you will owe requires your property's assessed value and the property tax rates based on your property's address. Please note that we can only estimate your property tax based on median property taxes in your area. There are typically multiple rates in a given area, because your state, county, local schools and emergency responders each receive funding partly through these taxes. In our calculator, we take your home value and multiply that by your county's effective property tax rate. This is equal to the median property tax paid as a percentage of the median home value in your county.

Montana Property Taxes
Buying a house in Billings? Missoula? Helena? If so, it’s a good idea to get familiar with the Montana property tax system. Montana has relatively low taxes on residential real estate. The state’s average effective property tax rate is 0.84%, lower than the national average of 1.08%.
In part, rates in Montana are low because the system is structured to reduce the burden on homeowners. The taxable value (the value on which your taxes are based) for an owner-occupied residential property is only a small percentage of the property’s market value. Commercial and business property also receive big exemptions.
If you are buying a house in Montana, it’s also a good idea to familiarize yourself with the details of getting mortgage in the Big Sky State. You can find this information, along with details about rates on our Montana mortgage guide.

How Montana Property Taxes Are Calculated
Property taxes in Montana are based on your total tax rate and the taxable value of your home. Taxable value is based on your home’s market value, but the state of Montana calculates it using a somewhat complicated formula.
First, residential property is reappraised by state assessors once every two years. (Reappraisal occurred every six years prior to 2015.) The goal of the reappraisal is to match the current market value for each property. If the reappraised value is greater than the previous value, the difference is phased in over the course of the two-year reappraisal cycle. That means there is a slight lag between your current market value and the value on which your taxes are based.
Taxes on residential properties are also limited by the fact that Montana only levies taxes on a small percentage of a property’s market value. This rate changes annually and the most recent rate is 1.35%. So for a home with a market value of $100,000, the taxable value is only $1,350. Your total state and local property tax millage rates (described in the next section) apply to that $1,350.
Montana Property Tax Rates
Cities, counties and school districts largely determine tax rates in Montana. The state also collects statewide taxes to support education. Tax rates are expressed in mills, or as millage rates. A mill equals $1 for every $1,000 of taxable value, while a millage rate is a mill expressed as a decimal. For example, 1 mill is equivalent to a millage rate of 0.001.
For example, the statewide taxes are 95 mills for public schools and another 6 mills for higher education.
While your tax bill will reflect a millage rate, a good way of comparing tax rates from one area to the next is through effective tax rates. This is equal to annual property taxes paid as a percentage of home value. The table below shows average effective property tax rates for every county in Montana, along with their median home values and median annual property tax payments.
|County||Median Home Value||Median Annual Property Tax Payment||Average Effective Property Tax Rate|
|Lewis and Clark||$220,600||$2,110||0.96%|

Our study aims to find the places in the United States where people are getting the most value for their property tax dollars. To do this, we looked at property taxes paid, school rankings and the change in property values over a five-year period.
First, we used the number of households, median home value and average property tax rate to calculate a per capita property tax collected for each county.
As a way to measure the quality of schools, we analyzed the math and reading/language arts proficiencies for every school district in the country. We created an average score for each district by looking at the scores for every school in that district, weighting it to account for the number of students in each school. Within each state, we assigned every county a score between 1 and 10 (with 10 being the best) based on the average scores of the districts in each county.
Then, we calculated the change in property tax value in each county over a five-year period. Places where property values rose by the greatest amount indicated where consumers were motivated to buy homes, and a positive return on investment for homeowners in the community.
Finally, we calculated a property tax index, based on the criteria above. Counties with the highest scores were those where property tax dollars are going the furthest.
