Montana Homestead Exemption: Rules & Savings

The Homestead Reduced Rate is graduated. Each portion of the property’s market value is assigned the rate for that bracket. A $900,000 home is not taxed entirely at 1.10%.

For tax year 2026, ordinary Class 4 residential property that does not qualify for a Homestead Reduced Rate or qualifying Long-Term Rental Reduced Rate is generally taxed at a flat 1.90% of market value.

Montana first applies the applicable classification tax rate to market value to determine taxable value. Local and statewide mill levies are then applied to that taxable value.

Seven months do not have to be one uninterrupted block

Montana DOR says the seven months generally do not need to be consecutive. Ordinary short absences such as vacations, medical stays or military deployment do not necessarily defeat qualification if the dwelling remains your principal residence.

A mobile or manufactured home used as the owner’s principal residence can qualify for the Homestead Reduced Rate, including when the home is assessed separately from the land.

The Homestead Reduced Rate applies only to the portion used as the qualifying principal residence. Other dwellings on the same geocode do not automatically inherit the Homestead rate.

The statutory principal-residence definition generally excludes separate contiguous or adjacent parcels. However, Montana DOR’s current FAQ recognizes circumstances where an adjacent parcel can be treated as integral to the homestead.

1. 1

   Confirm the dwelling is your principal residence

   Plan to own and occupy the property for at least seven months of the tax year.

2. 2

   Check your ownership structure

   Individual ownership, contract-for-deed interests and qualifying revocable grantor trusts can qualify. LLC and most other entity ownership do not.

3. 3

   Find the property’s 17-digit geocode

   Use Montana Cadastral or Property.MT.gov. Copy the geocode exactly from the property record.

4. 4

   Check existing Homestead enrollment

   Before filing a duplicate application, use DOR’s enrollment verification tool.

5. 5

   Gather owner information

   The application requires owner identification information, including Social Security information used by DOR to administer the program.

6. 6

   Enter the physical property address

   Use the actual principal-residence property rather than a mailing address that belongs to another property.

7. 7

   Make the principal-residence declaration

   You must attest under penalty of law that the ownership, occupancy and eligibility information is correct.

8. 8

   Submit before the current year’s deadline

   The ordinary statutory deadline is March 1. The 2027 enrollment period is currently open and closes March 1, 2027.

9. 9

   Save the application confirmation

   Keep the online confirmation, mailed copy and any supporting correspondence.

10. 10

    Verify approval

    Use DOR’s enrollment verification tool or your approval notice rather than assuming submission equals approval.

The geocode is a 17-digit property identifier used by Montana property systems. It is one of the most important details to have before starting a Homestead application.

For tax year 2026, an owner who received the qualifying 2025 property-tax rebate for the same residence can automatically receive the Homestead Reduced Rate if ownership has not changed and the home continues to be used as the qualifying principal residence.

Montana Code §15-6-407 creates a refund procedure for a homeowner who was eligible for the Homestead Reduced Rate but failed to claim it.

A home located on agricultural or forest property can still receive residential Homestead treatment. The residence and homesite are separated from the special valuation of the underlying farm or forest property.

1. 1

   Read the denial notice

   Identify whether the issue involves ownership, seven-month occupancy, another claimed principal residence, unpaid taxes, an entity-owned property or missing information.

2. 2

   Request DOR informal review within 30 days

   MCA §15-6-418 gives the owner 30 days after the denial notification to object using DOR’s written or electronic review process.

3. 3

   Explain extenuating circumstances where applicable

   The statute allows DOR to consider extraordinary, unusual or infrequent circumstances that are material and not expected to recur.

4. 4

   Review DOR’s determination

   The department must explain whether it accepts or denies the application after review.

5. 5

   Appeal further if necessary

   An aggrieved owner can appeal first to the county tax appeal board and then to the Montana Tax Appeal Board under the statutory process.

The Homestead Reduced Rate application is not simply an informal declaration. Montana law authorizes DOR to correct improperly granted reduced rates and imposes substantial consequences for a false or fraudulent application.

PTAP is separate from the Homestead Reduced Rate. It helps qualifying owners with fixed or limited income by reducing the applicable property-tax rate on the first $418,000 of the primary residence’s market value.

Applicants must own or be under contract to purchase the home and occupy it as their primary residence for at least seven months. A spouse’s income is included regardless of whether the spouse owns the property.

The Montana Disabled Veteran Assistance Program can provide a much larger property-tax rate reduction to a qualifying veteran who is rated or paid at the 100% disabled rate for a service-connected disability, or to certain unmarried surviving spouses.

An unmarried surviving spouse has a separate 2026 maximum FAGI of $54,573 and must meet the VA/death and unmarried-surviving-spouse requirements.

Montana now also has a Disabled First Responder Assistance Program for qualifying firefighters, law-enforcement officers, volunteer emergency care providers and qualifying unmarried surviving spouses.

Montana Title 70, Chapter 32 provides a traditional homestead exemption protecting a qualifying residence from execution or forced sale, subject to statutory exceptions.

If a claimant owns only an undivided fractional interest in the real property, MCA §70-32-104 limits that claimant’s exemption proportionately to the claimant’s interest.

What property can constitute the creditor homestead?

Montana law describes the homestead as the dwelling house or mobile home, its appurtenances and the land on which it sits, where the claimant resides.

How to establish it

1. 1

   Prepare a declaration of homestead

   The declaration must state that the person making it resides on the premises and claims the premises as a homestead.

2. 2

   Include the property description

   The statutory declaration requires a description of the premises.

3. 3

   Execute and acknowledge it properly

   MCA §70-32-105 requires the declaration to be executed and acknowledged in the same manner as a grant of real property.

4. 4

   Record it with the correct county

   MCA §70-32-107 requires recording in the office of the county Clerk and Recorder where the land is situated.

Claims that can still reach the homestead

• qualifying construction or vendor’s liens;
• mortgages properly secured by the premises;
• certain mortgages executed and recorded before the declaration; and
• other claims or procedures specifically permitted by Montana law.
