In the fast-paced world of commercial real estate and construction, the Section 179D tax deduction is a powerful tool for encouraging energy-efficient buildings. It offers significant tax savings for newly constructed buildings or upgrades to interior lighting, HVAC, and building envelope systems. But with the One Big Beautiful Bill Act (OBBBA) introducing changes effective as of July 4, 2025, and confusion around deadlines, forms, and compliance causing hesitation—especially among architects, contractors, and design professionals—it's easy to get tripped up by misinformation. You've likely heard colleagues venting about hurdles associated with securing allocation letters or questioning if retrofits even count.

Section 179D: A New Chapter Begins

On December 20, 2019 President Trump signed into law H.R. 1865 the Further Consolidated Appropriations Act, a $1.4 trillion federal spending bill. Included in this bill are numerous tax extenders, including an extension of the 179D Deduction. The extension of 179D means that building owner and designers of government owned buildings, placed in service through the end of 2020 can now claim benefits under 179D worth up to $1.80 per square foot. Taxpayers also have the ability to amend returns to claim missed tax incentives from previous years.

Seeking to rewrite the script on what has been a year devoid of many signature legislative achievements, Washington Republicans are on the verge of passing the most substantial piece of tax legislation in three decades. Last week, in a show of legislative and political nimbleness that eluded Republicans during the Obamacare repeal debate, the Senate passed its version of tax reform – setting up the massive tax package for enactment before the end of 2017.
