Section 179D of the Federal Tax Code Offers a Tax Deduction for Installing Energy Efficiencies in Real Property
Through §179D of the tax code, commercial building owners may be eligible for a federal tax deduction of up to $5 per square foot for improving the energy efficiency of new and existing buildings. This amount—which was increased significantly from the previous amount of $1.80 per square foot by the Inflation Reduction Act of 2022—is available for qualifying energy-efficient improvements to a building’s lighting system, HVAC system, and the building envelope. In addition to building owners, primary designers—including architects, engineers, green building consultants, and contractors—of qualifying energy efficiency measures in buildings owned by government and nonprofit entities may also claim the deduction.
Third-party certification is required to claim the §179D deduction, and Capital Review Group is a leading third-party certifier. Our experience has helped us simplify the certification process and allows us to offer the most competitive fees in this professional specialty.
Energy efficiency projects can generally deliver a positive return on investment when tax incentives are applied. However, capturing all beneficial incentives requires that both engineering and tax strategy are performed in sync. This is where CRG adds exceptional value for our clients.
