Exemption filing

For tax year 2026, Montana homestead and long-term-rental reduced-rate enrollment closed March 20, 2026. The 2027 application period is May 4, 2026–March 1, 2027; qualifying principal residences require at least seven months of occupancy and current taxes.

Senior relief

Montana Elderly Homeowner/Renter Credit: age 62 or older by December 31, Montana resident at least nine months, owned/rented/leased a Montana home at least six months, and total household income under $45,000; refundable credit up to $1,150. Montana also offers the income-based Property Tax Assistance Program and Disabled Veteran Assistance. Official information: https://revenue.mt.gov/property/property-tax-help/montana-elderly-homeowner-renter-credit.

Valuation limits

No county-specific annual assessed-value cap was verified. Montana DOR administers the 2025–2026 reappraisal cycle and local treasurers apply locally adopted mill levies and special assessments. The Montana homestead reduced tax rate is a rate reduction, not a county assessed-value cap.

For a valuation appeal, use the appeal date in the tax and filing section above. Keep your notice, supporting evidence, and proof of submission.
