Property Tax Exemptions You're Probably Not Claiming in Montana

Montana doesn't reduce your home's taxable value the way most states' exemptions do. It runs at least four separate relief programs, and most of them work by cutting the tax rate applied to your property instead, or in one case, by putting money back through your state income tax return rather than your property tax bill at all.

The broadest one, open to any owner-occupant

The Homestead Reduced Rate lowers the tax rate on a home you occupy as your principal residence for at least seven months of the year, compared to the standard rate for residential property generally. It isn't restricted to seniors, veterans, or any income bracket; any qualifying owner-occupant can get it. This one appears to need attention each year rather than a single filing that lasts indefinitely, so confirm your enrollment status and deadline with the Department of Revenue rather than assuming last year's enrollment automatically carries forward.

The general income-based program for everyone else

Separate from the veteran-specific program below, Montana runs the Property Tax Assistance Program (PTAP) for lower-income homeowners generally. It works on the same rate-reduction principle as the veteran program, but with a smaller benefit, lower income limits, and a cap on the value of the primary residence it applies to. Confirm current income limits and benefit levels directly with the Department of Revenue, since specific figures weren't consistently published in the sources checked for this article.

The one for 100% disabled veterans, reformed in 2023

Veterans with a 100% VA service-connected disability rating, and their unmarried surviving spouses, can apply for the Montana Disabled Veteran (MDV) Assistance Program, which reduces the tax rate on the first $350,000 of their home's market value, a threshold raised from $200,000 by a 2023 reform. The size of the reduction, 100%, 80%, 70%, or 50% of the normal rate, depends on income and marital status. For 2026, the income ceiling (based on 2024 federal adjusted gross income) is $62,598 if single, $72,229 if married or head of household, and $54,573 for an unmarried surviving spouse. You'll need a letter from the VA confirming your disability status, and if you're a surviving spouse, documentation that your spouse died on active duty, from a service-connected condition, or held a 100% rating at death. Apply by April 15; eligibility is reviewed based on income and occupancy each year, so a change in income is worth reporting rather than assuming coverage continues unchanged.

The one that isn't filed with the property tax office at all

The Elderly Homeowner/Renter Credit works completely differently from everything above. It's a refundable credit calculated using your income, rent, and property tax figures together, and you claim it through your Montana state income tax return, not a separate property tax application. It's easy to overlook specifically because it doesn't feel like a property tax program when you're filing your taxes.

What to actually check

Confirm your Homestead Reduced Rate enrollment is current for the tax year, since it appears to need renewed attention annually rather than a one-time filing. If you're a 100% disabled veteran, apply for MDV by April 15 and use the current $350,000 threshold and 2026 income limits, not older figures. And don't forget to look for the Elderly Homeowner/Renter Credit when you file your state income taxes; it's the one benefit on this list that has nothing to do with your property tax bill directly.
