Property Tax Breaks for Seniors in Montana (2026)

Updated August 12, 2026. Quick answer: Montana has two things worth knowing and they work in opposite ways. The Property Tax Assistance Program cuts the tax rate on the first $418,000 of your home’s market value — but it has no age test, only an income one. The relief that is actually keyed to age is the Elderly Homeowner/Renter Credit: a refundable income-tax credit of up to $1,150 from age 62, which you can claim even if you owe no income tax and are not required to file — and which a renter can claim too.

What Montana offers

• The Elderly Homeowner/Renter Credit — up to $1,150, refundable, from 62 — MCA § 15-30-2338 sets four tests: you reached age 62 during the claim period, lived in Montana at least nine months of it, occupied a Montana dwelling as an owner, renter or lessee for at least six months, and had gross household income under $45,000. § 15-30-2340(7) is the part that matters: the credit is refunded when it exceeds your tax, and “may be claimed even though the claimant has no income taxable under this chapter”. § 15-30-2340(6) caps it at $1,150.
• Renters are in the programme by design — 15% of your rent counts as property tax — § 15-30-2337(11) defines “rent-equivalent tax paid” as 15% of the gross rent, and § 15-30-2340(2) computes the renter’s credit from that figure exactly as a homeowner’s is computed from the tax bill. Montana’s Department of Revenue goes further and states that for someone living in a healthcare, long-term care, personal care or residential care facility, the allowed rent is the actual out-of-pocket rent, excluding board, housekeeping, transport and nursing or memory care — with a worksheet on page 10 of Form 2 for splitting the bill. A parent in assisted living is often eligible and almost never told.
• How the credit is actually computed — the $12,600 that is easy to miss — § 15-30-2337(8) defines “household income” as gross household income minus $12,600. The credit is your property tax billed (or rent-equivalent) less a reduction from the § 15-30-2340(4) schedule, which runs from nothing below $2,000 of household income to 5% of household income at $12,000 and over. Above $35,000 of gross household income the result is then multiplied down — 40% at $35,000–$37,500, 30%, 20%, 10%, and zero at $45,000 or more.
• The Property Tax Assistance Program — $418,000 of value, and nothing about age — MCA § 15-6-305 taxes the qualifying part of a primary residence at the normal rate multiplied by a percentage set by income. The Department of Revenue publishes the same thing the other way round — as a reduction of 30%, 50%, 80% of the normal rate — and applies it to the first $418,000 of market value for tax year 2026. For a single filer, on 2024 federal AGI excluding capital and income losses:

  If your 2024 federal AGI is	Your tax rate is reduced by
  $0 – $14,286	80%
  $14,287 – $19,532	50%
  $19,533 – $29,037	30%

  For married filers and heads of household:

  If your 2024 federal AGI is	Your tax rate is reduced by
  $0 – $19,249	80%
  $19,250 – $29,085	50%
  $29,086 – $38,917	30%

  There is no age requirement in any of it. A 40-year-old on the same income qualifies identically.
• The statute book is out of date on purpose — and by $68,000 — § 15-6-305(2) still reads $350,000 of market value and income bands starting at $13,590. Subsections (3) and (4) are why: the market-value figure is re-indexed after each reappraisal cycle and the income levels are adjusted annually by the PCE inflation factor defined in § 15-6-301, which is measured against the first quarter of 2023. The department’s published tax-year-2026 figure is $418,000 — $68,000 more than the statute, 19.4% higher. Read the statute alone and you will understate your own eligibility.
• Apply once for PTAP, every year for the credit — § 15-6-302(5) requires the PTAP application by April 15 of the first year claimed, after which “the applicant remains eligible … in subsequent years through the annual verification process … without the need to reapply” — the department re-checks your income each year instead. The elderly credit works the other way: § 15-30-2339 puts the claim on the same date as your income-tax return, or April 15 if you do not file one, and allows a revision within three years of that date — so a missed year is often still claimable.

The catch most senior-exemption roundups skip

Nothing here is an exemption, so nothing here shows up on your tax bill as a line. PTAP changes the rate applied to your property; the elderly credit arrives through the income-tax system months later. A Montana senior who looks at the bill for evidence that relief was applied will not find the reassurance a Florida or Texas homeowner gets, and may conclude nothing happened.

The department picks for you — but only among the programmes you applied for. § 15-6-302(11) directs it to award “the property assistance … that provides the greatest benefit to the taxpayer” across §§ 15-6-305, 15-6-311 and 15-6-314. That is a genuine protection against choosing the wrong form. It does nothing for the elderly credit, which lives in a different title and must be claimed separately.

A temporary stay in a nursing home does not end your primary residence. § 15-6-302(10) says so in terms — useful when a rehab stay runs long and someone assumes the exemption is lost.

How to apply

File Form PTAP with the Department of Revenue — online through its portal or on paper to a local field office — by April 15. Claim the Elderly Homeowner/Renter Credit on Montana Form 2 with Schedule 2EC; if you are not otherwise required to file, you file only to claim it, and the department’s TransAction Portal takes it for free. Keep the property tax receipt or rent receipts — § 15-30-2339(2) requires one with the claim. If you rent from a facility, ask for the statement that separates rent from services before you file.

Two things to check before you count on it

• Thresholds move. Age and income limits are reset by legislatures and are frequently indexed. Every figure above carries the year we confirmed it; confirm the current one before you budget around it.
• Your county or town may add its own. Statewide programmes are the floor. Counties and municipalities frequently run additional exemptions, and those are where a lot of real money sits.

Montana Veteran Property Tax Relief: Income-Banded Rate Multipliers

Mont. Code Ann. § 15-6-311 is the primary authority for this state-specific rule.

• Montana makes the residential real property of a qualified veteran or qualified veteran's spouse eligible for a tax-rate reduction rather than a fixed value deduction.
• Property owned by a qualified veteran uses the cited income table's 0%, 20%, 30%, and 50% rate multipliers.
• The qualifying income levels are adjusted annually with the statutory PCE inflation factor, rounded to the nearest dollar, and may not decrease from the prior year's levels.

Before applying, match the rating letter, ownership, occupancy, survivor status, and filing timing in your records to the controlling text; confirm current filing instructions with the administering agency.
