Your home's market value

About $600,000. Drag to match your assessment (find it on your Montana DOR classification notice, not Zillow).

This is my primary residence (homestead rates)

Homestead means you live there 7+ months a year. You have to enroll with the Montana Department of Revenue to get these rates. They are not automatic. Enrollment for the 2027 tax year is open now and closes March 1, 2027: enroll here. Untick this for second homes and non-qualifying rentals, which pay a flat 1.9%. On a $600,000 home that is the difference between $4,871 and $11,400 of taxable value.

Show me the math

Montana taxes homes on a fraction of market value: taxable value = market value × residential rate. A mill is one dollar of tax per $1,000 of taxable value: annual cost = taxable value ÷ 1000 × mills. A dollar-amount levy converts to mills by dividing by the district's total taxable value: mills = levy ÷ district taxable value × 1000.
