The State Historic Preservation Tax Credit Program provides a state income tax credit for the sensitive, substantial rehabilitation of historic buildings. It ensures character-defining features and spaces of buildings are retained and helps revitalize surrounding neighborhoods. The program provides an income tax credit of up to 25% of qualified rehabilitation expenditures (QREs).

Review Process

The State Historic Preservation Office of Iowa (SHPO) has a 90-day review period from the date a complete application for each Part is received. However, the 90-day period is not binding. For incomplete applications, the review will be placed on hold until all information is provided. At the time all requested information is received, the 90-day review period will restart. The application may be denied if any requested information is not provided. Parts 2 and 3 reviews will not start until payment of the review fee has been received.

Additionally, if the completed rehabilitation work does not meet The Secretary of the Interior’s Standards for Rehabilitation as determined by the State Historic Preservation Office, or if the applicant does not otherwise comply with the terms of the agreement, law, or regulations, tax credits will not be awarded. Awarded credits may also be subject to recapture as described in Iowa Code.
