Commercial Buildings Tax Deduction Calculations Made Easier with New Tools

January 14, 2025 By Building Potential staff

The U.S. Department of Energy (DOE) has launched the 179D Portal, which hosts two free tools to estimate potential federal tax deductions for installing eligible energy-efficient technologies in commercial buildings.

Energy-efficient technologies can increase building performance and save on utility bills. Now, the new 179D Portal can estimate how building upgrades can qualify building owners and designers for a tax deduction, to further impact the bottom line, with tax deductions ranging from $0.58 to $5.81 per square foot.

To be eligible for a tax deduction, at least 25% savings must be achieved through interior lighting; heating, ventilation, or air conditioning; water heating; and/or building envelope system improvements as part of a new construction or building retrofit project.
