Historic Architecture / Rehabilitation Tax Credits


*Starting August 15, 2023, both the National Park Service (NPS) and SHPO will only be accepting electronic submissions for the Federal Historic Rehabilitation Income Tax Credit Program. As part of this change, NPS has issued revised application forms and documentation requirements, available for download from their website. Please review all new documentation guidance and contact the Historic Architecture Specialist with any questions.*

Our office is the statewide facilitator for both the Federal and State Historic Rehabilitation Income Tax Credit Programs. These credits offer income tax credits for the rehabilitation of income-producing properties listed in the National Register of Historic Places. Both programs incentivize the revitalization of income-producing historic real estate and level the playing field when redevelopment exceeds the cost of new construction.

The Federal tax credit uses a three-part application to award successful applicants an income tax credit equal to 20% of their rehab investment. The State of Montana’s income tax credit is equal to 25% of the amount an owner claims under the Federal program. Those wishing to claim the state credit must first be certified for credits under the Federal program.



We offer technical advice to building owners, architects, and engineers concerning:

  • the treatment of historic building materials,
  • use of historically appropriate modern materials,
  • rehabilitation of historic interior finishes and the building envelope, and
  • handicapped accessibility


Some state-owned properties on which we advise include those in Virginia City, Reeder's Alley in Helena, and the Moss Mansion in Billings.


In addition to our statewide advisory role, we review and comment on work proposed for historic properties owned or funded by federal agencies such as the National Park Service, Forest Service, and HUD. These buildings range from the great hotels in Glacier National Park to vernacular architecture in our historic neighborhoods.


Answers to Frequently Asked Questions

The SHPO does not administer a grant for historic home preservation. The only grant programs for homeowners that we are aware of are from HUD and USDA-RD. Homeowners looking for financial assistance should contact these agencies directly with inquiries.

The SHPO administers the Federal Historic Preservation Tax Credit at the state level and is the liaison between applicants and the Federal Government. This tax credit equals 20% of the applicant's rehab investment in their historic income-producing building. The State of Montana offers a state tax credit equal to 5% of the applicant's rehab investment.

Local governments may adopt a property tax abatement program for the rehabilitation of historic buildings. Contact your local government to determine if they offer this program.

Owners of National Register-listed properties may do what they wish with their private property and private funding. If property owners use federal dollars, federal incentive programs, or do work that requires a federal permit, the federal agency must consult with SHPO under Section 106 of the National Historic Preservation Act. State agencies that own historic properties must consult with SHPO under the Montana State Antiquities Act. Local governments might also have design guidelines that property owners are required to follow.

Property owners are encouraged to contact the SHPO with questions about best practices in preservation and historically sensitive rehabilitation. The SHPO recommends and will advise owners to let the building's history and architecture speak for itself and not be the subject of conjectural embellishment. We recommend that owners planning a rehabilitation project review the Secretary of the Interior's Standards for the Treatment of Historic Properties.
