Proposed Legislation to Extend the §179D Energy Efficient Commercial Building Deduction


This week, the “Tax Extender Act of 2017” was filed in Senate, which extended several expired tax deductions including §179D Energy Efficient Commercial Building Deduction (§179D Deduction).


The §179D Deduction is a Federal tax incentive promoting energy efficient buildings for both new and existing structures. Further, architects, engineers, contractors, environmental consultants or energy services providers may also be eligible for the incentive on public projects. This incentive is often referred to as the EPAct Deduction after the Energy Policy Act of 2005 that created it, or as the §179D Deduction, which relates to its tax code section. Commercial building owners can take a Federal tax deduction of up to $1.80 per square foot of the building’s floor area if they install certain property (e.g., efficient lights or HVAC systems, added wall or roof insulation, etc.) that reduces energy and power costs. The §179D Deduction is allowed for both new construction and renovations completed between 2006 through 2016.


The proposed legislation extends the §179D Deduction beyond 2016 and allows taxpayers to take it for projects completed in 2017 and 2018.


A recent study published by a leading regional economic modeling and policy analysis firm published a report on of the economic effects of extending the §179D Deduction and the results were astounding. The analysis shows that in addition to advancing the goal of energy independence, the §179D Deduction is an engine of economic and employment growth.


Out of all the buildings that qualify, very few taxpayers are taking the steps necessary to claim this valuable incentive. While currently expired, the §179D Deduction often provides current benefit on projects from 2016 and prior. ICS can provide a free analysis to determine if this incentive is feasible, and if so, provide the necessary third-party certifications and other assistance to benefit from it. For a free consultation, please contact an ICS Tax representative.
