Montana senior property tax guide
Last updated: 24 September 2026
Montana does not use one simple senior property tax exemption. Older homeowners may need to check several programs, while renters age 62 or older have a separate refundable credit. The right route depends on income, age, ownership, occupancy, and deadlines.
Bottom Line
If you own and live in your Montana home on a limited income, check the Property Tax Assistance Program first. If you are 62 or older, also check the senior homeowner/renter credit. Every homeowner should verify whether the home has the Homestead Reduced Rate, because the 2027 enrollment period is open through March 1, 2027.
The 2026 PTAP and Montana Disabled Veterans deadline was April 15. Late applications are considered for the following tax year.
Start Here
- Check your homestead status. If this is your main home, confirm that the property is enrolled for the reduced rate.
- Match the program to your situation. PTAP is for qualifying lower-income homeowners. The senior credit can help qualifying owners and renters age 62 or older.
- Keep the county bill separate from the relief application. Your county treasurer collects the tax. Do not let a pending credit or review make you miss a county payment deadline.
If you are unsure what type of relief you are looking at, the GFS guide to property tax relief terms explains exemptions, credits, rebates, freezes, and deferrals.
| Your situation | Best first route | Important timing |
|---|---|---|
| Lower-income homeowner | PTAP | 2026 deadline passed; late applications move to the following year |
| Age 62+ homeowner or renter | Elderly Homeowner/Renter Credit | Use the tax-year rules for the year you claim |
| Principal residence | Homestead Reduced Rate | 2027 enrollment closes March 1, 2027 |
| 100% disabled veteran | MDV assistance | 2026 deadline passed; late applications move to the following year |
| Family land with very high land value | Land Value program | Ask DOR for the next filing window |
What Has Changed
- 2027 homestead enrollment is open. Montana says the application period runs from May 4, 2026, through March 1, 2027.
- The 2026 homestead rates are now in effect. The state uses four market-value brackets for enrolled principal residences. These rates help determine taxable value; local mill levies and special assessments still affect the final bill.
- The main 2026 PTAP and MDV deadline has passed. Both programs use an April 15 deadline. Montana says late applications are considered for the following year.
- The 2025–2026 late appraisal-review window has closed. The special June 1, 2026, late date for Form AB-26 is past. If you have a new notice or decision, use the deadline printed on that notice and contact the Department of Revenue promptly.
Main Montana Programs to Check
Montana property tax relief combines rate reductions with a refundable income tax credit. A senior may fit more than one route. Use the GFS Property Tax Relief Finder to organize what to check, and the state-by-state tax guide if you are comparing Montana with another state. Montana agencies make the official eligibility decisions.
| Program | Who it may help | Key 2026 fact |
|---|---|---|
| PTAP | Lower-income homeowners | 30%, 50%, or 80% rate reduction on the first $418,000 of market value |
| Senior credit | Owners or renters age 62+ | Refundable credit up to $1,150 for the 2025 claim year |
| Homestead rate | Principal-residence owners | Tiered reduced rates for enrolled homes |
| MDV assistance | Qualifying 100% disabled veterans or certain surviving spouses | 50%, 70%, 80%, or 100% rate reduction based on income |
Property Tax Assistance Program (PTAP)
What it does: PTAP reduces the property tax rate on part of a qualifying homeowner’s primary residence. It is not a cash grant. For Tax Year 2026, the benefit applies to the first $418,000 of the home’s market value.
Who may qualify: You must own the home, mobile home, or manufactured home, or be buying it under contract. You must use it as your primary residence for at least seven months of the year. For Tax Year 2026, Montana uses 2024 Federal Adjusted Gross Income, excluding capital and income losses. The limit is less than $29,037 for a single applicant and less than $38,917 for a married applicant or head of household. A spouse’s income is included even if the spouse is not an owner.
How much can it reduce? The state uses three income bands. The reduction is 80%, 50%, or 30% of the normal property tax rate on the eligible value. The official PTAP income table shows the exact bands.
How to apply: The 2026 filing deadline was April 15. Montana says an application filed after the deadline is considered for the following year. Do not guess that the 2026 income limits will be the 2027 limits; the state updates income ranges for inflation.
Reality check: PTAP lowers the tax rate on eligible value. It does not erase county special assessments or guarantee that the total bill will fall by the same percentage as the PTAP reduction.
Elderly Homeowner/Renter Credit
What it does: The Montana Elderly Homeowner/Renter Credit is a refundable income tax credit of up to $1,150. It can help homeowners and renters, including people who otherwise do not have to file a Montana income tax return.
Who may qualify: For the year being claimed, you must be age 62 or older by December 31, live in Montana for at least nine months, occupy a Montana home as an owner, renter, or lessee for at least six months, and have total household income under $45,000.
How the amount is figured: The formula uses household income, qualifying property tax, and qualifying rent. The 2025 Schedule 2EC uses 15% of qualifying rent in its calculation before other adjustments and the $1,150 maximum.
Care facilities: If you live in assisted living, personal care, long-term care, or another residential care setting, only the actual out-of-pocket rent portion can count. Meals, housekeeping, transportation, nursing care, assisted living care, and memory care are not treated as rent. The state explains this on its credit guidance page.
If you missed the regular return: Montana’s 2025 income-tax instructions allow an amended return when a taxpayer is claiming a Montana credit not previously claimed. If you have not claimed the 2025 senior credit, ask the Department of Revenue or a qualified tax preparer which filing route applies to you. For broader state tax questions, GFS’s Montana senior tax guide covers other tax issues for older adults in the state.
Homestead Reduced Rate
What it does: This is a reduced property tax classification for a principal residence. It is not limited to seniors. To qualify as a homestead, the owner generally must live in the home for at least seven months of the year and be current on property taxes.
2026 rate structure: Montana’s 2026 tax information lists a tiered rate: 0.76% on the first $378,000 of market value, 0.90% on the portion from $378,001 through $756,000, 1.10% on the portion from $756,001 through $1,511,999, and 1.90% on the portion at $1,512,000 or more. These percentages are part of the taxable-value calculation. Local mill levies and special assessments still affect what you actually owe.
2027 enrollment: The homestead program page says enrollment for Tax Year 2027 runs from May 4, 2026, through March 1, 2027.
If you received the 2025 rebate: The state says you generally did not need to re-enroll for the 2026 reduced rate if you received the 2025 property tax rebate, still own the same home, and live there as your principal residence for at least seven months in 2026. Verify rather than assume, especially after a move, sale, transfer, or ownership change.
If you bought a home after the 2026 deadline: Montana’s homestead FAQ says a qualifying buyer of a home that was not already enrolled may be taxed at the standard 1.90% rate for 2026 but may request a refund of the difference between January 1 and May 31, 2027, after paying 2026 property taxes in full. The home must meet the principal-residence rules. The new owner also needs to enroll for 2027 by March 1, 2027.
Do not confuse programs: A Montana homestead declaration used for creditor protection is different from the Homestead Reduced Rate used for property taxes.
Other Property Tax Programs That May Matter
Land Value Property Tax Assistance
The Land Value program is narrow but important for some longtime Montana families. The Department of Revenue says the land’s appraised value must be at least 150% greater than the value of the home and other buildings. The home must be on five acres or less, be the primary residence for at least seven months, and the land generally must have been owned by the applicant or a family member within three degrees of kinship for at least 30 consecutive years.
The public page still shows deadlines tied to the 2025–2026 valuation cycle. Those dates are past, so ask the Department of Revenue for the next filing window. Gather documents that show the ownership chain.
Montana Disabled Veterans Assistance
The MDV program may reduce the property tax rate for a veteran with a 100% service-connected disability, or for certain unmarried surviving spouses. For Tax Year 2026, the top Federal Adjusted Gross Income limits are $62,598 for a single applicant, $72,229 for a married applicant or head of household, and $54,573 for an unmarried surviving spouse. The reduction can be 50%, 70%, 80%, or 100%, depending on income.
The 2026 application deadline was April 15. Late applications are considered for the following year. Older veterans can also use the GFS guide to Montana veteran benefits for other state and federal help.
Property Tax Bills, Deadlines, and Appeals
Montana’s Department of Revenue values and classifies property, but county treasurers collect residential property tax. The state’s residential property page says the first real-property payment is due by 5 p.m. on November 30 or within 30 days after the tax notice is postmarked, whichever is later. The second payment is due by 5 p.m. on May 31. If a due date falls on a weekend or holiday, it moves to the next business day.
If you are short on money: Call the county treasurer before the due date. Ask for the exact amount due, how the county treats the deadline, and whether any local payment option is available. Do not assume a state credit or appeal stops delinquency.
If the property value looks wrong
For the 2025–2026 valuation cycle, the appraisal review page required Form AB-26 within 30 days of the classification and appraisal notice. A special late window ran through June 1, 2026, for Tax Year 2026 adjustments. That late window is now closed.
If you receive a new notice or a decision from an informal review, do not use an old deadline from this article. Follow the date on the notice. Direct appeals to a County Tax Appeal Board generally must be filed within 30 days of the appraisal notice, or within 30 days after a Department of Revenue informal-review decision. If you are already appealing and want to preserve a refund claim, ask the county treasurer about the rules for paying disputed property tax under protest.
How to Start Without Wasting Time
- Pull the current tax bill and notices. Do not work from last year’s bill if a new one is available.
- Find your property record. Write down the geocode, ownership, market value, and classification.
- Verify homestead enrollment. A move or ownership change can change whether the reduced rate carries forward.
- Check PTAP or MDV for next year. Filing after April 15 can still place the application into the following year’s process.
- Check the senior credit separately. A renter may qualify even though PTAP is only for qualifying homeowners.
- Save proof. Keep confirmation numbers, mailed copies, tax bills, rent receipts, and notes from calls.
Documents to gather
- Current property tax bill or rent records
- Property address and geocode
- Federal tax return and income records for the applicable year
- Social Security or other nontaxable income statements when requested
- Department of Revenue letters and appraisal notices
- VA disability letter for MDV
- Facility rent breakdown for care settings
- Deeds or ownership records for the Land Value program
If housing costs are the larger problem, see GFS’s Montana housing assistance guide. If the home needs repairs that are making it hard to stay safely housed, see Montana home repair help. If care costs are also affecting the household budget, the Montana home care guide explains ways to pay for care at home.
Who Handles What
| Question | Best office | What to ask |
|---|---|---|
| PTAP, MDV, homestead status | Montana Department of Revenue | Eligibility, application, status, needed documents |
| Market value or classification | DOR field office | Property record, appraisal, review rights |
| Amount due or delinquency | County treasurer | Payoff, due date, payment method, local options |
| Senior credit | DOR income tax | Schedule 2EC, rent proof, amended filing |
| Title or ownership problem | Legal assistance | Trust, deed, estate, transfer, or probate issue |
Reality Checks
- A rate reduction is not the same as a bill reduction. Mill levies and special assessments still matter.
- PTAP uses an older income year. Tax Year 2026 uses 2024 Federal Adjusted Gross Income.
- The senior credit uses household income. It is not based only on the older person’s taxable income.
- Rent rules can be strict. Some tax-exempt housing does not qualify, except for rent paid to a county or municipal housing authority.
- Expired deadlines matter. Do not publish or rely on the old June 1, 2026, appraisal-review date as if it were still open.
Common mistakes to avoid
- Assuming Montana has one senior exemption that covers everyone.
- Using the old PTAP $350,000 benefit cap instead of the verified 2026 $418,000 figure.
- Assuming the 2026 PTAP income limits are automatically the 2027 limits.
- Counting assisted-living services as rent for the senior credit.
- Confusing a homestead declaration with the Homestead Reduced Rate.
- Waiting for an appeal or credit while the county bill becomes delinquent.
Denied, Delayed, or Overwhelmed
Ask for the reason in writing. A denial may involve income, occupancy, ownership, missing documents, or a filing date. Homestead denials have an informal review route. Valuation disputes use the review or County Tax Appeal Board process tied to the notice.
For a senior-credit problem, ask whether a corrected or amended return is the right fix. For deed, trust, probate, or inherited-property problems, legal help may be more useful.
If the tax bill is only one part of a larger money problem, the Montana senior benefits guide can help you check food, utilities, health, housing, and other assistance. For lower-cost recreation, see GFS’s Montana recreation discounts guide. For tax filing or IRS-related questions, use GFS’s tax help guide.

Resumen en Español

Si tiene 62 años o más, el crédito para propietarios e inquilinos mayores puede ofrecer hasta $1,150. También revise la Homestead Reduced Rate. La inscripción para 2027 está abierta hasta el 1 de marzo de 2027. Para ayuda, llame al Departamento de Ingresos de Montana al 406-444-6900 o a su tesorero del condado.

Frequently Asked Questions
Does Montana have a senior property tax freeze?
Montana’s current Department of Revenue property-tax help page does not list a broad statewide age-based property tax freeze. The main statewide routes include PTAP, the Elderly Homeowner/Renter Credit, the Homestead Reduced Rate, disabled-veteran assistance, and the Land Value program.
What are the 2026 PTAP income limits?
For Tax Year 2026, 2024 Federal Adjusted Gross Income, excluding capital and income losses, must be less than $29,037 for a single applicant and less than $38,917 for a married applicant or head of household. PTAP applies to the first $418,000 of the primary residence’s market value.
Can Montana renters age 62+ qualify?
Yes. The Elderly Homeowner/Renter Credit can help qualifying renters age 62 or older. For the year claimed, the person must meet the age, nine-month Montana residency, six-month home occupancy, and household-income rules. Some tax-exempt housing does not qualify.
When is 2027 homestead enrollment due?
Montana says the 2027 Homestead Reduced Rate enrollment period runs from May 4, 2026, through March 1, 2027. A new owner, a person who moved, or someone who did not receive the 2025 rebate should not assume enrollment carried over.
What if I bought a home after the 2026 deadline?
If the home was not already enrolled, Montana says a qualifying new owner may be taxed at the standard 1.90% rate for 2026 but may request a refund of the difference between January 1 and May 31, 2027, after paying the 2026 property taxes in full. The owner must also enroll for 2027 by March 1, 2027.
What if my appraised value seems too high?
For the 2025–2026 valuation cycle, Form AB-26 was normally due within 30 days of the appraisal notice, and the special late window ended June 1, 2026. If you have a new notice or a Department of Revenue decision, follow the deadline on that document and contact the local DOR field office promptly.
