2025 Tax Information for Montana Property Owners

In 2025, Montana is changing how it calculates property taxes for many types of property, including homes, farms, businesses, and forest land. These changes affect how much property owners will pay and how tax rates are applied based on a property's value and use. This page explains the new rates and who they apply to so you can understand what to expect and how your property is classified.

New Tiered Tax Rates for 2025

Starting in 2025, Montana is implementing a graduated property tax system for residential, multifamily, commercial, and industrial property. You do not need to apply to qualify.

How the new rates work for residential and multifamily properties:

  • 0.76% on the first $400,000 of market value
  • 1.10% on the portion between $400,000 and $1.5 million
  • 2.20% on any portion over $1.5 million

This tiered structure applies to:

  • Single-family homes
  • Townhomes and condominiums
  • Manufactured and mobile homes (including up to 1 acre of land)
  • Vacant and improved residential lots
  • Multi-family residential property

Multifamily commercial property includes all income-generating facilities that provide long-term housing, such as:

  • Apartments
  • Duplexes
  • Senior living facilities
  • Nursing homes

For multifamily rental dwellings with a market value greater than $2 million, the maximum graduated tax rate is 1.89%.

Tax Rates for Non-Residential and Agricultural Properties

For tax year 2025, Class 4 commercial and industrial property (vacant and improved lots) will be taxed using a graduated rate structure:

  • 1.40% on the first $400,000 of assessed value
  • 1.89% on value above $400,000

  • Flat tax rate on land: 14.35%
  • Improvements, including the 1-acre homesite, will be taxed using the 2025 residential tiered rate structure

Parcels of 160 acres or more are automatically classified as agricultural unless used for other purposes. Smaller parcels may qualify if they meet income requirements and are used for agricultural purposes.

  • Tax rate for qualified agricultural land: 2.05%
  • Improvements, including the 1-acre farm site, will be taxed using the 2025 residential tiered rate structure
