A number of different people can take advantage of the Section 179D deduction for an energy-efficient building — and of Concord’s unmatched expertise on the subject.


Because the governmental entities are not subject to taxation, the government owner of a building cannot claim the Section 179D deduction.

However, it can allocate all or part of the tax deduction to a designer who creates the technical specifications that create energy-efficiency in the qualifying property and its subsystems. (The eligible subsystems are HVAC/hot water, building envelope, and lighting.)

This is accomplished by means of an Allocation Letter — a document Concord can prepare for you to have signed by the government owner. Concord can also serve as a liaison between you and your client in securing these signatures through our dedicated government relations staff.

Most firms operating in the A/E/C industry have the opportunity to qualify as a designer for the Section 179D deduction.  For more specific information on how your firm can capitalize on this opportunity, click the link below.

Design/Build Firms


Most improvements to commercial property take a long time to recover — as long as 39 years through the standard system of capitalization and depreciation deductions.

But Section 179D allows an owner to earn an accelerated deduction of as much as $1.80 per square foot by significantly improving the energy-efficiency of new construction or retrofits. (In exchange for the immediate deduction, the owner must reduce their basis in the property by the amount of the deduction.)
