How are the taxes determined on my property?
The amount of taxes payable annually on a property is the result of the assessment process and the total mill levies for the taxing authorities that provide public services.
The Montana Department of Revenue establishes the value of all property for tax purposes. The taxing authorities use the assessed value to determine their mill levies. A mill is 1/10th of a penny or $1.00 revenue for each $1,000 of assessed valuation. Information concerning the tax levy can be obtained by contacting the governing boards of the taxing entities.
Information concerning assessments and appraisals can be obtained from the Department of Revenue at 406-444-4000.
