Montana property tax calculator
Homeowners in Montana pay a median of $2,693 each year. That amount equals 0.72% of $375,800, the median home value.
This provides an estimate rather than a bill. Your county assessor, or appraisal district in some states, determines your value; local taxing units establish the rates. Check with your county before making a payment or filing a protest.

Other Montana property tax rules to know
- You can still request an informal review until June 1, 2026, even if you miss the 30-day window. A valuation change made after the deadline applies only to tax year 2026.
- The reduced rate can apply to landlords' long-term rentals, including properties held by an LLC, corporation, or irrevocable trust. Such property does not qualify for the homestead rate.
- Any right to an interest-bearing refund after a successful valuation dispute requires a written protest filed with the county treasurer and payment under protest by the deadline.
- The Montana Tax Appeal Board can review a County Tax Appeal Board's decision that you dispute. File your appeal within 30 days after receiving the decision.
