Energy Efficient Commercial Building Deduction

Decrease your tax liability with the federal tax incentive for energy-efficient buildings.

What is the deduction?

The Internal Revenue Code Section 179D deduction allows the owner of a commercial building to receive a tax deduction for a building that is constructed or renovated in an energy-efficient manner.

It provides an immediate first year tax deduction for specific energy-efficient portions of a new or remodeled commercial building. To claim the deduction, these building components must be tested and certified as attaining specific savings compared to a 2001 energy standard. 

A maximum deduction is allowed if the overall components attain a 50 percent energy savings compared to the standard, limited to $1.80 per square foot. Partial deductions are allowed for any one of the three systems that reach a required percentage of savings, with the deduction for each system capped at $.60 per square foot. Starting in 2021, the amount will be increased in line with inflation.

Do you qualify?

The deduction is available to the owner or lessee of a commercial building for qualified new construction, renovations, or additions. Single-family homes, multifamily structures under four stories, and mobile or modular homes do not qualify.

The deduction applies to structures built since 2006, including:

  • New commercial buildings (office buildings, retail space, restaurants, and manufacturing facilities and warehouses)
  • Retrofitted buildings
  • Leadership in energy and environmental design (LEED) buildings

Building features that qualify for the deduction include:

  • Lighting systems
  • Heating, cooling, ventilation, and hot water systems (HVAC)
  • Building envelope construction (i.e., insulation, doors, and windows) or retrofitting
