Property Tax Rates Across Montana
Local government entities set tax rates, which can vary widely within a state. Why? Because annually, each county estimates its required budget to provide services and divides that by the total value of all taxable property within its jurisdiction. This calculation results in the property tax rate. While there are votes and laws involved in setting tax rates and budgets, in a nutshell, this is the annual process. Below, you can compare a Montana county’s effective property tax rate to other counties in Montana or the U.S. median property tax rate. For instance, Blaine County has the highest effective property tax rate in Montana, at 1.39%, while Carter County has the lowest, at 0.41%.
Our median effective property tax rate (tax bill ÷ assessor's market value) accounts for exemptions and deductions, making it more accurate than the general median tax rate, which is the midpoint of statutory rates before adjustments.

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 May. 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. By providing insights into how assessed and market values are determined, this section helps property owners navigate their tax responsibilities and understand the valuation processes affecting their property taxes in Montana. For example, Gallatin County has the highest median home price at $644,700.
