How Does the Montana Property Tax Calculator Work?

Use this Montana property tax calculator to estimate your annual property tax bill. Enter your property's assessed value and our calculator applies Montana's median effective tax rate of 0.78% to generate an estimated bill.

Enter your property's estimated assessed value — the value your county assessor assigns to your property, which is typically lower than market value after exemptions. Our calculator uses the median effective tax rate (actual bills divided by assessed market value), accounting for typical exemptions and providing a more accurate estimate than the statutory rate alone.

Note: your assessed value reflects any exemptions you currently hold. Your actual bill may be higher or lower depending on local levies, special assessments, and individual exemption eligibility.

Montana's median property tax rate is lower than the national median property tax rate of 1.02%, but the median property tax bill is higher than the national median property tax bill of $2,400. The highest median property tax bill is in Missoula at $4,658, while Carter has the lowest at $411. County tax bills are $159 higher.

What Are Effective Property Tax Rates in Montana?

Local government entities set tax rates, which can vary widely across Montana. Each county estimates its required budget to fund public services and divides that by the total assessed value of all taxable property in its jurisdiction. This calculation produces the effective tax rate.

Below, compare any Montana county's effective rate to other counties in the state or the national median of 1.02%.

For instance, Dawson County has the highest effective property tax rate in Montana at 1.46%, while Carter County has the lowest at 0.42%.

Our median effective rate (your actual tax bill divided by the assessor's market value) accounts for all exemptions and deductions, making it more accurate than the general statutory millage rate.

Property Tax Assessment Values Across Montana

Understanding the distinction between "market value" and "assessed value" is crucial when examining property taxes in Montana.

The market value is what a willing buyer would pay to a willing seller in an open and competitive market. Location, property condition, and economic market trends often influence it. Each Montana county assessor estimates the market value for tax purposes.

The assessed value is the market value minus any applicable exemptions or limits determined by local laws and offerings. The tax assessed value is the figure used to calculate your property taxes or the amount multiplied by your tax rate to get your tax bill.

Assessment notices:

In Montana, assessment notices are sent in the spring each year. They'll typically reach your mailbox by the end of March.

Each property owner receives an assessment notice that contains both the market value and assessed value, along with an estimate of your property tax bill. Montana’s median home price is $317,000, and the median property tax bill is $2,559, slightly above the national median property tax bill of $2,400. For example, Gallatin has the highest median home price at $642,000.
