What is the 179D Tax Deduction and how does it work?

179D is a federal incentive intended to stimulate the U.S. economy by rewarding architecture, engineering, and design-build contractor businesses with up to $5.65 per square foot for their work on government-owned buildings. The deduction is allowed for both new construction and past projects going back to 2019.

Who Can Claim 179D?

Architects, engineers, and design-build contractors that work on new or renovated government-owned buildings and structures, for example:

K-12 Schools
Military Bases
City Parks
Tribal Lands
