Understanding Your County Property Taxes

CLOSED: This discussion has concluded.
  • Assessed value is estimated by the Montana Department of Revenue. Every two years, the Montana Department of Revenue completes an appraisal of all properties in Montana’s 56 counties. This appraisal sets what the state uses as the market value of your home or property for the calculation of the taxable value.
  • Taxable value is based on laws the Montana Legislature passes. The Montana Department of Revenue calculates each property’s taxable value based on exemptions and limitations in laws enacted by the Montana Legislature. The taxable value for your property is listed on your appraisal notice from the Montana Department of Revenue. All residential homes are taxed at 1.35% of the property’s assessed value.
  • County mill rate is set by Missoula County voters and the county commissioners. Missoula County voters have approved spending measures for County services such as weed management, search and rescue teams and parks and trails. All these items are reflected in the number of mills the County will levy. After over 100 hours of presentations and deliberations, Missoula County commissioners finalize the County budget and the mills required to support other necessary County services.
  • Calculate your taxes by taking your taxable value and multiplying it with the County’s FY23 mill rate, then divide that by 1,000. This calculation will only represent services provided by Missoula County. Based on the location of your property, taxpayers will also pay property taxes to local school districts, special districts and City of Missoula taxes. A total tax bill calculation, listed on your tax bill, includes all taxing jurisdictions and amounts each district assesses. Learn more at https://svc.mt.gov/dor/property.
