What Are Historic Commercial Tax Credits?

Historic Commercial Tax Credits incentivize the preservation and productive reuse of certified historic buildings by offsetting federal income tax liability tied to rehabilitation costs. The incentive is designed to preserve architectural heritage while encouraging private investment in older commercial structures.These credits apply only to income-producing properties and require strict adherence to federal preservation standards.

Federal Historic Tax Credit Overview

The Federal Historic Tax Credit (HTC) is governed by the Internal Revenue Code and administered jointly by the IRS and the National Park Service (NPS).Key characteristics:Applies to certified historic structuresLimited to income-producing commercial properties
  • Based on qualified rehabilitation expenditures (QREs)
  • Claimed after project completion and certification
The credit is not automatic. Eligibility, project scope, and execution must align precisely with regulatory requirements.

How Commercial Properties Qualify

To qualify, a project must satisfy all of the following:Building Requirements
  • Listed individually on the National Register of Historic Places, or
  • Located in a registered historic district and certified as contributing
Use Requirements
  • Property must be used for income-producing purposes
  • Residential owner-occupied properties are excluded
  • Mixed-use buildings may qualify for the commercial portion only
Rehabilitation Standards
  • Work must comply with the Secretary of the Interior’s Standards for Rehabilitation
  • Alterations must preserve historic character, materials, and architectural features
Failure in any one area can disqualify the entire credit.

Qualified Rehabilitation Expenditures (QREs)

QREs form the financial base of the credit calculation. Not all costs qualify.Commonly Eligible Costs
  • Structural systems and building envelope work
  • Electrical, plumbing, and HVAC upgrades
  • Interior finishes tied to historic preservation
  • Architectural and engineering fees related to rehabilitation
Commonly Excluded Costs
  • Acquisition price of the building
  • New construction or building additions
  • Landscaping and site work
  • Furniture, fixtures, and equipment
  • Financing and leasing costs
Precise cost classification is essential. Mischaracterized expenses are a frequent audit trigger.

Project Timing and Certification Process

Historic tax credits follow a multi-phase approval structure:Phase 1 – Historic SignificanceConfirms the building’s historic status.Phase 2 – Rehabilitation PlanReviews proposed work for compliance with preservation standards.Phase 3 – Project CompletionCertifies that completed work matches the approved plan.Timing matters. Credits are tied to project completion and placed-in-service dates, not when costs are incurred.

Interaction With State Historic Tax Credits

Many states offer separate historic tax credit programs that can complement the federal credit.Important considerations:
  • State rules often differ from federal standards
  • Credits may be refundable, transferable, or capped
  • Coordination is required to avoid compliance conflicts
Sum It Credits evaluates federal and state programs together, not in isolation, to prevent downstream issues.

Common Misconceptions and Disqualifiers

Misconceptions
  • “Any old building qualifies”
  • “Cosmetic updates are enough”
  • “Credits can be estimated early without risk”
Disqualifiers
  • Starting work before approvals
  • Non-compliant design changes mid-project
  • Improper cost segregation
  • Failure to maintain income-producing use
Historic credits are unforgiving. Errors are often irreversible.
