Montana homeowners have a deadline staring them down, and ignoring it could mean paying more than necessary in 2026. March 1 stands as the date that matters. That deadline connects directly to the new reduced property tax rate available to qualifying homeowners for the 2026 tax year. Anyone who owns and occupies a primary residence in Montana needs to understand what the state requires, how the reduced rate works, and what action must happen before that calendar page turns.
Montana lawmakers approved changes that create a lower tax rate for certain owner-occupied homes, and the Montana Department of Revenue now requires homeowners to claim that status properly. The savings will not land automatically for everyone. Eligibility depends on how the property is classified and whether the homeowner files the required application or verification by March 1.
