Historic Property Preservation Credit
Publication revised September 24, 2026. Sourcebook page 170.
Credit amount / calculation
25% of the federal rehabilitation credit attributable to qualifying Montana property.
Business fit and eligible activity
A qualifying historic industrial rehabilitation can generate a state credit. Eligible property rehabilitation or redevelopment; not the cost of wood supplied to someone else's project.
Illustrative business benefit
If the qualifying federal rehabilitation credit is $400,000, the Montana calculation is $400,000 x 25% = $100,000, subject to the state tax-liability limit. It is not 25% of the entire construction budget.
Timing / first action
Tax-year claim: document the eligible expense, hire or placed-in-service date and meet any separate certification deadline. Establish that the property and rehabilitation are eligible before demolition, construction, or irreversible design work begins.
