Historic Preservation Tax Credit
Publication revised September 24, 2026. Sourcebook page 111.
Credit amount / calculation
Percentage of qualified rehabilitation expenditures under current IEDA program rules.
Business fit and eligible activity
Certified historic mills and industrial buildings can qualify for an allocated rehabilitation credit. Eligible property rehabilitation or redevelopment; not the cost of wood supplied to someone else's project.
Eligibility and practical use
This is not a general construction credit. It becomes relevant when the real estate itself has the required historic, abandoned, brownfield, or redevelopment status. Advance certification is especially important here.
Illustrative business benefit
Use-of-credit illustration, not an estimated award: assume the agency or completed tax form establishes a $1,000 credit for the qualifying activity described above. If sufficient eligible tax is due, a $1,000 credit available for current use reduces that tax by $1,000. If annual limits allow only $600, that is this year's saving; the other $400 survives only if the carryforward or transfer rules permit. Obtain the actual program calculation before estimating a project benefit. Page
Timing / first action
Seek approval before signing a purchase order, contract, lease or other binding commitment. Confirm the exact point at which a purchase order, contract, lease, or other binding commitment would make the project ineligible.
