State Historic Preservation Income Tax Credits

Rehabilitation of residence for tax creditsColorado offers a state income tax credit to property owners for preservation and rehabilitation work on designated historic properties. The credit is 20% of the qualified rehabilitation costs up to a maximum $50,000 credit per qualified property.   

Denver Landmark preservation staff processes state income tax credit applications for historic properties within the City and County of Denver. Owners are advised to obtain appropriate tax advice to ensure that all requirements are met. 

How to Apply

In order to qualify for the state historic preservation income tax credit, there are eligibility requirements related to the historic property, the taxpayer, and the project type and costs. 

Eligible Properties

To participate in the program, a property must be historically designated by one of the following: 

  • National Register of Historic Places 
  • Colorado State Register
  • City and County of Denver  - designated as an individual landmark, or  a "contributing" property (historic property)  in a Denver historic district.  
    Use the Find Landmarks / Districts tool to the right to determine the landmark status of your property.  If you are unsure if your property is a "contributing" property in a historic district, contact Landmark Preservation staff.

Eligible Taxpayers:

  • Property owners or tenants with leases of five (5) or more years
  • Residential or commercial property owners

Eligible Project Types and Costs:

  • Projects must involve physical preservation, restoration or rehabilitation of historic buildings.   A project can include multiple work items.

    Eligible costs include but are not limited to carpentry, plaster, painting, ceilings, fixtures, door and window repairs, fire sprinklers, roofing, exterior repairs, attic insulation, and tuckpointing of brick.

    Ineligible costs include the following:
  • Soft costs, such as architectural and engineering fees, acquisition costs, building permit and inspection fees, insurance, temporary power, etc.
  • Routine or periodic maintenance, such as routine painting 
  • Repairs to outbuildings less than 50 years old
  • New construction, as well as repairs to additions that were built after a property received historic designation
  • Interior furnishings
  • Grading, paving, landscaping work
  • Other costs may be ineligible.  Coordinate with Landmark Preservation staff to determine if work items are eligible.

  • Projects must preserve the historic character of the property and  meet the Secretary of the Interior's Standards for Rehabilitation. Denver Landmark Preservation and the Denver Landmark Preservation Commission will review your application to ensure that these standards are met.
  • Rehabilitation costs must be over $5,000.  You can reach the $5,000 minimum through one work  item or multiple smaller work items.
  • If the project is either a Denver landmark or located in a locally-designated historic district, all exterior work items must receive a Certificate of Appropriateness.  See design review to learn how to obtain a Certificate of Appropriateness.
  • Projects should not be underway at time of application.

    While the tax credit rules technically allow applicants to apply for the program if work has started within 24 months prior to project application, application submittal does not guarantee project approval.  Applicants who submit an application after beginning work run the risk of project disapproval if program requirements are not met.

Applicants should review the program requirements, complete the Part I application form (PDF) and receive Part I approval from Landmark Preservation prior to beginning work.

Since 2011, the availability of the Colorado Historic Preservation Tax Credit in any given year has been contingent upon whether the state anticipates a revenue surplus for that year. In years when the tax credit is unavailable, property owners can claim the tax credit in the first year that it becomes available again.  

2013 Update
The Colorado Department of Revenue reactivated the 20 percent historic preservation income tax credit for 2013.  Historic property owners who complete qualified rehabilitation work in 2013 are eligible to claim a 20 percent tax credit for project costs on 2013 state income tax returns (filed in 2014). Projects must be completed in 2013, as verified by Denver Landmark Preservation, once part I (preliminary) and part II (completion) tax credit applications are filed and approved.  

Property owners who completed tax credit rehabilitation projects in 2011 and 2012, but were ineligible to claim the credits for those tax years due to insufficient state revenue growth, can also claim the tax credit on their 2013 state income tax returns (filed in calendar year 2014).  

How to Apply
The property owner is responsible for requesting tax credits by submitting Form 104CR or Form 112CR to the Colorado Department of Revenue. An approval certificate provided by Denver Landmark Preservation must be attached to your Colorado income tax return.

Please note: if a property owner obtains tax credits and then sells the property within five years of project completion, the state will require that a portion of the credit be recaptured.

Applicants are advised to obtain the necessary tax and legal advice to ensure that they qualify for the state income tax credit.
