The short version: Montana moved from one flat residential rate to a tiered system, cut the rate on primary homes and long-term rentals, and raised it on second homes and short-term rentals. The two bills were HB 231 and SB 542, and they phase in over two tax years.
Before 2025, every home in the state was taxed on 1.35% of its appraised value. For the 2025 bills you got in November, that became a three-step ladder based on dollar value.
| 2025 tax year, all homes | Rate |
|---|
| First $400,000 of value | 0.76% |
| $400,001 to $1.5 million | 1.10% |
| Above $1.5 million | 2.20% |
Starting with the 2026 bills, the ladder is tied to the statewide median home value (set at $395,400) and it splits by how the home is used. A "homestead" is your primary residence, or a rental leased for at least seven months a year on leases of 28 days or more.
| 2026 and after, homestead | Rate |
|---|
| Up to $395,400 | 0.76% |
| $395,401 to $790,800 | 0.90% |
| $790,801 to $1,581,600 | 1.10% |
| Above $1,581,600 | 1.90% |
| Second homes and short-term rentals, any value | 1.90% |
| Homes on agricultural land, non-homestead | 1.35% |
Rates are the share of appraised value that's taxable; the local mills then apply to that. Commercial property went to 1.5% up to about $2.1 million and 1.9% above.
What that means in practice, by the state's own estimates: owner-occupied homes down roughly 18% from 2024, long-term rentals down about 22%, and non-homestead homes up about 68%. Your actual bill depends on your mills, so Bozeman, Big Sky and Ennis all land differently.
Three things to do. First, if you own and occupy your home, make sure you're enrolled for the homestead rate at homestead.mt.gov. Owners who got the 2025 rebate were enrolled automatically; everyone else, and every landlord, has to apply, and the deadline for the 2026 bills was March 1, 2026. Late applicants may still be able to appeal for a refund. Second, if you own a second home or a short-term rental here, budget for the 1.9% rate and talk to me before you decide whether to convert it to a long-term rental, sell, or hold. Third, if you think your appraised value is above market, you can appeal it with the Department of Revenue, and I'll pull the comparables for you.
Agricultural land kept its 2024 treatment, and the bill to tighten the $1,500 income threshold for ag status failed. The 2027 session will almost certainly revisit all of this, which is the main reason I write the Legislative Watch.
