About Property Taxes in Montana
Montana property taxes are administered at the county level. The state Department of Revenue appraises property at market value and applies a class rate to determine the taxable value. Residential property is appraised at market value, and the taxable value equals a percentage of that (the residential class rate is set by the state legislature and has been reduced in recent years to around 1.35% of market value — meaning a $300,000 home has a taxable value of approximately $4,050). Montana has no sales tax, so property taxes are an important revenue source for local governments and schools. Tax bills are mailed in the fall and split into two payments.
Payment & Assessment
Montana property taxes are paid in two equal installments: First half: Due November 30 Second half: Due May 31 of the following year A 2% penalty per month (up to 10%) applies to late payments. Most counties offer online payment through the county treasurer's website. Contact your county treasurer for available payment options.
