Big changes are coming to Montana property taxes, and they could save you a bundle—or cost you more if you're not paying attention. Starting Monday, Montana property owners can apply for a new 'homestead' tax exemption that could significantly lower their tax bills beginning in 2026. But here's the twist: many eligible homeowners are already enrolled automatically, leaving others scrambling to figure out if they need to act. Here’s what you need to know to avoid missing out.
The Montana Department of Revenue (DOR) kicked off applications on December 1 for this game-changing exemption, which applies to primary residences and long-term rentals. Here’s the catch: while property tax rates will drop for those who qualify, they’ll rise for those who don’t. And this is the part most people miss: if you claimed the state tax rebate on your primary residence earlier this year, you’re likely already enrolled. DOR sent letters to rebate recipients confirming they don’t need to apply—unless they’ve sold their property or changed their primary address. Still unsure? You can check your enrollment status on the DOR website here.
According to DOR estimates, about 220,000 to 225,000 primary residences are automatically enrolled, but another 10,000 owners will still need to apply. But here’s where it gets controversial: all long-term rental owners must apply directly, even though DOR expects only 50,000 to 60,000 applications for roughly 115,000 units. Why the gap? Some landlords might not realize they’re eligible, while others could be hesitant to navigate the process. If you’re in this category, don’t delay—the March 1 deadline for the 2026 tax year is closer than it seems.
Applying is straightforward: DOR offers both online and printable forms on its website here. But here’s a thought-provoking question: Is this exemption truly fair? While it benefits homeowners and long-term renters, it shifts the tax burden onto non-exempt properties. What do you think? Does this policy strike the right balance, or does it unfairly penalize certain property owners? Let us know in the comments—this is a conversation worth having.
