Historic Homes Rehabilitation Tax Credit


The Historic Homes Rehabilitation Tax Credit (HHTC) program is designed to encourage new homeownership and to assist existing homeowners in maintaining or rehabilitating their historic property.

The HHTC program provides a 30% tax credit voucher, up to $30,000 per dwelling unit on eligible rehabilitation expenditures that meet the $15,000 minimum expenditure level and can be directly attributed to the long-term preservation of the historic building fabric.

            Example: A one-family home can apply for $100,000 in eligible rehabilitation expenditures and receive the maximum $30,000 tax credit voucher if the projects meet the Standards for Rehabilitation.

Quick answers:

  • A tax credit reservation is issued when the part 2 application is approved. The reservation is the amount of money set aside while the owner completes the project—it is calculated based on 30% of the total anticipated project costs. The applicant has 5 years to complete the work before the reservation amount expires. SHPO adds a 10% contingency
  • By statute there is no provision for increasing the amount of a tax credit reservation if the work comes in higher in cost than anticipated.
  • The reservation turns into the voucher when the part 3 application is approved. The final voucher amount may vary from the reservation amount. At the end of the project, the applicant will earn the lesser of either the tax credit reservation, or 30% of the project’s final qualified rehabilitation expenditures.
  • A tax credit voucher is not the same as funds issued to the homeowner. The tax credit voucher can only be used or claimed by a Connecticut C-Corporation to off-set their state income tax. An applicant must sell the voucher to a CT C-Corporation to receive funds. 
  • A homeowner can find a CT C-corporation on their own or engage with a tax credit broker. There is no guarantee every CT C-Corporation will purchase the historic tax credit vouchers, or purchase them dollar-for-dollar. The CT C-Corporation's payment timeline is not determined by SHPO.
