_{Guidance on Qualified Rehabilitation Expenditures from the IRS}

The National Park Service Technical Service Bureau shared guidance from the IRS regarding Qualified Rehabilitation Expenditures. View a pdf of the new guidance here.

The guidance has incorporated detailed information on costs associated with flood adaptation which can be used in conjunction with the Guidelines of Flood Adaptation for Rehabilitating Historic Buildings (TPS 2021). It classifies QRE from non-QRE, and identifies those that may be QRE, depending on the situation.

Additionally, you’ll find information on costs related to renewable energy sources including solar panels, wind turbines, and geothermal systems.
