If you own a home in Montana and live there at least seven months of the year, you may qualify for the state’s reduced homestead property tax rate. Your property taxes need to be current, and the home must be owned by an individual, a couple, or a qualifying revocable trust. The state applies the reduced rates in brackets, so each rate applies to just a portion of the home’s market value.
Own a long-term rental? It may qualify for a reduced rate, too. The property has to serve as a tenant’s residence and be rented for at least 28 days at a time and at least seven months out of the year. The property taxes need to be current. If you live in one unit and rent out another on the same property, you’ll need to enroll the rental separately.
Enrollment for the 2027 tax year is open through March 1, 2027. If you’re unsure whether your property is already enrolled, you can look it up online before you apply. And if you qualified for the homestead rate in 2026 but didn’t receive it, you may be eligible for a refund.
