Reviewed October 17, 2026. Equipment, commercial real estate and rental housing have different rules. Confirm the property’s classification and your eligibility before including savings in a business plan.
Qualifying business equipment: first $1 million exempt
Montana exempts the first $1 million of statewide aggregate market value of Class 8 property. This can include equipment, furniture and fixtures. It is a property-tax exemption, not a $1 million income-tax deduction or cash credit. Values across Montana locations are combined; related entities may be aggregated when a parent owns at least 50%.
Example: $600,000 of qualifying equipment may fall entirely within the exemption. Land and buildings do not become exempt with it. Use assessed market value rather than assuming the purchase price or accounting book value controls.
Official equipment exemption and valuation rules →Reporting can still be required
The Department’s 2026 notice requires reporting for equipment with statewide aggregate market value of $1 million or more as of January 1. Below-threshold businesses may still need to report after acquisitions, because of related entities, or when the Department requests it. Confirm treatment at exactly $1 million.
The published reporting deadline is February 15. Late reporting can trigger a penalty. Keep an asset list and confirm your requirement with Revenue, even if you expect no equipment tax.
Official 2026 reporting notice →Commercial buildings and land: separate assessment
For 2026, Revenue lists commercial and industrial property rates of 1.50% below the published $2,274,000 threshold and 1.90% at or above it. Ask the assessor how the classification and threshold apply to the parcel.
These assessment rates are not the final annual property-tax bill as a percentage of the property’s value. Local levies and other applicable charges affect the bill. Get the parcel’s assessment and county tax estimate before buying.
Official 2026 property classifications and rates →Rental housing: use and eligibility matter
Qualifying long-term rentals receive different treatment from short-term rentals. Revenue describes qualifying rentals as rented for at least 28 days at a time for at least seven months of the year. Its published 2026 application window ended March 1, 2026. Check current eligibility and any available correction process directly.
A Montana LLC alone does not establish eligibility, change a property’s use or remove taxes in another state. Before transferring title, ask a Montana CPA or attorney about tax treatment, financing, insurance and ownership consequences.
Official rental-property guidance →Before claiming a benefit
Record the parcel or equipment location, ownership, actual use, property class, assessed value, related ownership and filing deadlines. Request confirmation from Montana Revenue or the county assessor and review it with your tax professional.
