The Historic Tax Credit Program
The federal Historic Tax Credit (HTC) — authorized under Section 47 of the Internal Revenue Code — provides a 20% tax credit against qualified rehabilitation expenditures (QREs) incurred in the certified rehabilitation of a certified historic structure. The credit is intended to incentivize the preservation and adaptive reuse of historically significant buildings by making rehabilitation financially competitive with new construction.
The federal program is administered jointly by the National Park Service (NPS), which reviews historic significance and rehabilitation work for consistency with the Secretary of the Interior's Standards for Rehabilitation, and the IRS, which administers federal tax eligibility and credit-claiming rules. Illinois separately offers a state historic-preservation credit, subject to state allocation, certification, cap, utilization, and sunset requirements.
Historic tax credits are distinct from Low-Income Housing Tax Credits in program structure, investor requirements, and transaction mechanics — but HTC and LIHTC are frequently combined on rehabilitation projects that involve both historic structures and affordable housing, and the interaction between the two programs requires careful structuring.
