Montana's New 2026 Property Tax Rules: What Buyers, Sellers, and Second-Home Owners Must Know
Date: Tuesday, August 25, 2026
Category: Montana real estate
Coverage: Primary residences, long-term rentals, second homes, short-term rentals, vacant residential lots
Tax year: 2026
Montana’s 2026 property tax structure separates residential property into two primary categories:
Principal residences and qualifying long-term rentals: Tiered rates from 0.76% to 1.90%
Second homes, vacation homes, and short-term rentals: Flat 1.90% rate
The classification affects ownership costs, investment projections, listing decisions, and the total cost of buying a home in Montana.

2026 Rate Structure
Date: Tuesday, August 25, 2026
Category: Primary residence and long-term rental rates
The reduced rate applies to an enrolled principal residence or qualifying long-term rental. The calculation is incremental. Each portion of market value receives the rate for its bracket.
The 1.90% rate for an enrolled primary residence or long-term rental applies only to the portion of value at or above the highest threshold.
The 2026 statewide median value used for the residential tiers is approximately $378,000. The thresholds correspond to the median value, twice the median value, and four times the median value.
The tiered structure generally applies to the home and up to one acre of homesite land when the property meets the applicable requirements.
Second Homes and Short-Term Rentals
Date: Tuesday, August 25, 2026
Category: Non-principal residences
The flat 1.90% rate applies to the full residential market value of:
Second homes
Vacation homes
Short-term rentals
Airbnb and VRBO properties
Cabins used for short stays
Vacant residential lots
Other non-principal residential property
The flat rate does not use the lower 0.76%, 0.90%, or 1.10% tiers.
For a typical residential property, the home and up to one acre of homesite land are subject to the 1.90% rate when the property is classified as a second home or short-term rental.
Example: $600,000 Property
Date: Tuesday, August 25, 2026
Category: Tax comparison
A $600,000 property produces different rate calculations based on its classification.
Enrolled primary residence or qualifying long-term rental
First $378,000 at 0.76%: $2,872.80
Remaining $222,000 at 0.90%: $1,998.00
Illustrative total under the listed rate structure: $4,870.80
Second home or short-term rental
Full $600,000 at 1.90%: $11,400
The example represents the stated rate calculation before any local factors, exemptions, classification adjustments, or other elements included on a property tax bill.
The same distinction becomes more significant as property value increases. A $1 million primary residence may receive several lower tiers before reaching the 1.90% bracket. A $1 million second home or short-term rental receives the 1.90% rate across the full value.
Requirements for the Tiered Primary Residence Rate
Date: Tuesday, August 25, 2026
Category: Homestead eligibility
A property must meet Montana’s requirements and be enrolled to receive the reduced rate.
A qualifying principal residence generally requires:
Owner occupancy for at least seven months of the year
Current property tax payments
Ownership by an individual, couple, or grantor revocable trust
Properties owned by an LLC, partnership, corporation, or irrevocable trust generally do not qualify for the homestead reduced rate.
A buyer moving to Montana should identify the intended principal residence before closing and review the enrollment process with the Montana Department of Revenue and the county appraisal office.
Automatic qualification may apply in limited circumstances to owners who received the 2025 property tax rebate and continue to own and occupy the home for at least seven months of 2026. A buyer who acquired the property during 2026 should not assume that a prior owner’s status transfers automatically.

Requirements for the Long-Term Rental Rate
Date: Tuesday, August 25, 2026
Category: Rental property eligibility
A rental property can qualify for the tiered residential rate when it meets the long-term rental requirements.
The property must generally be:
Rented for at least 28 days per tenant
Rented for at least seven months of the year
Used as the tenant’s residence
Current on property tax payments
Enrolled through the required process
Long-term rental eligibility differs from short-term rental use. A property rented for weekend stays, weekly stays, or other vacation purposes remains subject to the flat 1.90% rate.
Ownership treatment also differs. Montana allows qualifying long-term rentals owned by an LLC, corporation, or irrevocable trust to receive the reduced rental rate. The eligibility requirements still apply to the property’s use and enrollment.
Multifamily property requires separate review. For 2026:
Long-term rental multifamily property: 1.10% flat rate
Short-term rental units: 1.90% flat rate
Owner-occupied unit: Applicable residential tiered rates
Owners with mixed-use properties should verify how each dwelling unit is classified.
Considerations for Montana Luxury Real Estate
Date: Tuesday, August 25, 2026
Category: High-value residential property
Montana luxury real estate requires a tax analysis based on property use, not only purchase price.
For an enrolled primary residence valued above $1,512,000, only the value above that threshold receives the 1.90% rate. The lower tiers still apply to the portions below the threshold.
For a second home or short-term rental, the entire residential value receives the 1.90% rate. This affects:
Annual ownership projections
Vacation home budgets
Short-term rental financial models
Buyer qualification
Net operating income
Resale positioning
Property management decisions
A buyer considering a high-value property near Whitefish, Kalispell, Lakeside, or another Montana market should model taxes under the intended use.
Agricultural and Forest Land
Date: Tuesday, August 25, 2026
Category: Acreage, farms, ranches, and recreational property
Properties with agricultural or forest classifications require additional analysis.
Non-qualified agricultural land
Land: 14.35% flat rate
Primary residence or long-term rental: Home and one-acre homesite use residential tiered rates
Second home or short-term rental: Home and one-acre homesite use the 1.90% flat rate
Qualified agricultural land
Agricultural land: 2.05% flat rate
Primary residence or long-term rental: Residential tiered rates
Second home or short-term rental: 1.35% flat rate for the residential portion
Forest land
Forest land: 0.37% flat rate
Primary residence or long-term rental: Residential tiered rates for the dwelling and applicable homesite
Second home or short-term rental: 1.90% flat rate for the dwelling and applicable homesite
A property’s land classification does not automatically determine the dwelling’s residential classification. Buyers should review the parcel, homesite, dwelling, ownership structure, and intended use as separate items.
What Buyers Should Verify Before Closing
Date: Tuesday, August 25, 2026
Category: Buying a home in Montana
Before submitting an offer or finalizing a purchase, request:
Current market value
Current property tax bill
Residential classification
Homestead or long-term rental enrollment status
Acreage and homesite classification
Agricultural or forestland status
Short-term rental permits and restrictions
Local zoning requirements
Homeowners association rules
Expected use after closing
The prior owner’s tax status may not match the buyer’s intended use. A primary residence may become a second home. A short-term rental may be converted to a long-term rental. A long-term rental may become owner-occupied.
Each change can affect eligibility, enrollment, and projected tax costs.

Category: Selling Montana property
Sellers should assemble accurate property information before listing:
Current tax bill
Property classification
Enrollment documentation
Rental agreements
Rental history
Short-term rental permits
Agricultural or forestland records
Homesite acreage
Ownership structure
A seller should not advertise a tax classification as a permanent benefit for the next owner. The buyer’s occupancy, rental use, ownership structure, and enrollment status may control future treatment.
Tax information should be presented as a current property record, not as a guarantee of future tax liability.
