Federal Historic Preservation Tax Incentives Program


The Federal Historic Preservation Tax Incentives Program encourages private sector rehabilitation of historic buildings and is one of the nation's most successful and cost-effective community revitalization programs. It generates jobs and creates moderate and low-income housing in historic buildings.

The program is administered by National Park Service and the Internal Revenue Service in partnership with State Historic Preservation Offices. OHP's Architectural Review and Incentives Unit administers the Federal Historic Preservation Tax Incentives Program and provides consultation and architectural review based on conformance with the Secretary of the Interior’s Standards for the Treatment of Historic Properties (Standards).

Internal Revenue Code Changes in the 20% Historic Tax Credit

On December 22, 2017, Public Law No: 115-97 (Pub. L. 115-97) was signed and enacted, amending the Internal Revenue Code subsection 47 to reduce tax rates and modify policies, credits, and deductions for individuals and businesses.  Pub. L. 115-97 (Sec. 13402) modifies the 20% Historic Rehabilitation Tax Credit as well as provides certain transition rules.  These and other changes to the Internal Revenue Code may affect a taxpayer's ability to use the 20% Historic Tax Credit.  Pub. L. 115-97 also repeals the 10% Rehabilitation Tax Credit for non-historic buildings.  The text of Pub. L. 115-97 is available at www.congress.gov

Applicants requesting historic preservation certifications by the National Park Service as well as others interested in the use of these tax credits are strongly advised to consult an accountant, tax attorney, or other professional tax adviser, legal counsel, or the Internal Revenue Service regarding the changes to the Internal Revenue Code related to Pub. L. 115-97.


Tax Credit Application Submittal Guidance

Don't let this happen to you or your client: the return of a tax credit application due to a technical mistake or incomplete form. The information, hyperlinks and checklist provided in  Completing a Successful Tax Credit Project Application will practically guarantee that your tax credit application will not be returned due to common yet preventable errors. Download this guidance today!

Don't let this happen either: The return of an application because the photos and other documentation don't meet the National Park Service criteria.  Download Guidance for NPS Documentation submittals.

Photo Submittals

Due to the uneven quality of photo submittals, OHP can only accept individual, unbound, 4" x 6" or larger color photos on glossy photo stock, properly labeled on the back or photo margin ONLY. Any other format will be returned. Refer to Park Service criteria above for the approved format.

Design-Build Issues

OHP has recently been experiencing lack of Standards compliance due to the use of Design-Build mechanical installations which were not coordinated with tax credit review.

Use of the Design-Build process risks the loss of tax credits due to lack of proper review.  Make the design team aware of character-defining features of the project and the need for review of any impact to those features.

Use the Revised Tax Credit Application Forms

The NPS has revised the Historic Preservation Certification Application forms and instructions. Applicants should begin using the Rev. 2019 applications immediately. Current forms all display "Rev. 2019" in the upper left hand corner of the forms.

Applications submitted on forms other than "Rev. 2019" will be returned to the Applicant for resubmission.

NPS Review Fees Paid Online Through Pay Portal

All Part 2 and Part 3 applications will be billed by TPS and payment will be made through Pay.gov, the US Department of the Treasury’s electronic payment system, by credit card or ACH bank payment. Upon receipt of a Part 2 or Part 3 application, TPS will generate an invoice delivered by email. Invoices for applications without email addresses will be mailed via the United States Postal Service.
