Federal Historic Preservation Tax Incentives Program


The Federal Historic Preservation Tax Incentives Program provides a federal income tax credit for the sensitive rehabilitation of historic buildings. It ensures that character-defining features of buildings are retained and helps revitalize surrounding neighborhoods.

Eligibility Requirements

The federal tax credit program provides either a 20% historic tax credit or a 10% non-historic income tax credit, based on the qualified rehabilitation expenditures and dependent upon the type of building as described below. For both tax credit amounts, the buildings must be used for income-producing purposes and the rehabilitation must be “substantial" (see below).

1) For the 20% historic rehabilitation tax credit, the building must be listed on the National Register of Historic Places individually or as a contributing resource in a listed historic district, or it must be evaluated as meeting the qualifications set for National Register listing by the U.S. Secretary of Interior. In these cases, the property must be listed within 30 months after claiming the credit on IRS forms.

To qualify for the 20% tax credit for historic buildings, the rehabilitation must be approved as meeting The Secretary of the Interior's Standards for Rehabilitation and Guidelines for Rehabilitating Historic Buildings. This ensures that the work is consistent with the historic character of the building and, if applicable, the surrounding historic district.

Contact Elizabeth (Beth) Foster Hill, Tax Incentive Programs Manager/National Register Coordinator, at (515) 281-4137 or Beth.Foster@iowa.gov to find out your building’s National Register status or for information about how to nominate a property to the National Register of Historic Places.

2) For the 10% rehabilitation tax credit, the building must have been first used or occupied prior to 1936, the building cannot be used for residential purposes, and it cannot be listed on the National Register of Historic Places individually or as a contributing resource in a National Register-listed historic district. The State Historic Preservation Office does not review projects applying for the 10% credit. For more information go to the IRS website.

For both tax credits, there should be "substantial rehabilitation" of the building within a 24-month period. This means that the amount invested into the rehabilitation must exceed the "adjusted basis" or depreciated value of the building. In some instances, the substantial rehabilitation for 20% tax credits may extend up to 60 months and across several phases.
