Montana property tax mill levies by county

What the figures are

This page reproduces the Department of Revenue's mill levies for each county by part, in mills (dollars per $1,000 of taxable value), with the tax dollars they raised. The state, county and county-wide school levies apply across the whole county; the local school, miscellaneous and fire district, and city figures are averages across the districts in the county. The table prints no total rate, so this page gives none and does not add the parts. Period: tax year 2024 (bills November 2024 and May 2025), from the Department of Revenue's 2022-2024 biennial report, the latest published (the 2024-2026 report, which would carry tax year 2025, was not yet listed on October 26, 2026).

State assessed mills. State assessed mills include: 6 mills for the university system, 33 mills for elementary equalization and BASE program support, 22 mills for high school equalization and Base program support, 40 mills for state equalization aid to public schools, and 1.5 mills to support vocational-technical education. (Table 6.13, footnote 1)

City average mills. Total taxes from mill levies of all cities/towns within a county divided by total taxable value of the cities/towns. (Table 6.13, footnote 2)

• Mills apply to taxable value, not market value, so they cannot be read as a percentage of what a property is worth.
• Most counties show 101 state mills; Cascade, Lewis & Clark, Missoula, Silver Bow and Yellowstone show 102.5, which matches the footnote's 1.5 vocational-technical mills.
• The table's statewide row prints total taxes and fees of $2,588,468,287, but its own components, and the 56 county totals, add up to $2,593,035,431, $4,567,144 more. This page uses the sum of the county totals and does not repeat the printed statewide figure as a total.

Statewide: the 56 county totals add up to $2,593,035,431 of taxes and fees; the table's printed statewide total is $2,588,468,287, which does not match its own parts.

Montana's table prints no total rate and its mills apply to taxable value, not market value, so no example bill is computed.

How to appeal an assessment in Montana

1. Request an informal review from the Department of Revenue on Form AB-26: within 30 days from the date on the classification and appraisal notice.
2. Or appeal directly to the County Tax Appeal Board through the county clerk and recorder: within 30 days of the notice date.
3. Further appeal to the Montana Tax Appeal Board; its decisions are final unless taken to district court: the Department's page gives no deadline for this step.

The Department's page also cites MCA 15-1-402 for paying disputed taxes under protest. Sources: Montana Department of Revenue, Property Informal Review and Formal Appeal Process, read October 26, 2026. The official notice and the body hearing the appeal govern the dates; this is not legal advice.

Checks: the table was read twice, independently, and both reads agreed on every column compared for all 56 counties; for every county the component revenues plus SIDs and fees equal its printed Total of All Taxes & Fees within $2 (rounding); every county shows 101 or 102.5 state mills, as the footnote explains; no county's county levy lies outside three interquartile ranges of the others and no two neighbouring rows repeat the same figures.
