For more than a decade, the 179D Energy Efficient Commercial Buildings Deduction<\/a><\/strong> has been a meaningful federal incentive for architecture and engineering firms working on tax-exempt projects such as K-12 schools, municipal buildings, state and city facilities, higher education campuses, healthcare systems, and other nonprofit-owned properties. But the 179D opportunity phases out under current rules, and the window is narrowing.<\/p>\n

Under current rules, projects must have substantial construction begin before June 30 of this year to qualify. After that date, new projects will no longer be eligible under the existing framework. <\/p>\n

There is still time to act.<\/strong> <\/p>\n

Projects completed within the past three tax years may still qualify if 179D was not previously claimed. Projects that begin substantial construction before the deadline can also generate deductions. For firms that have not recently reviewed their portfolio, this is a critical window to determine whether value remains on the table. <\/p>\n

However, 179D has largely been a project-based incentive. As it phases out, leadership should evaluate longer-term federal strategies that apply across the broader firm. <\/p>\n

One of the most relevant is the Research and Development Tax Credit. <\/p>\n

\"\"<\/figure>\n

The R&D Credit in the Current Legislative Environment <\/h2>\n

Recent changes under the One Big Beautiful Bill<\/a><\/strong> have reshaped the landscape around capitalization of research expenses. With the repeal of mandatory amortization and the restoration of immediate expensing for domestic research costs, the R&D Credit has regained its full economic impact. <\/p>\n

For architecture and engineering firms, this is particularly significant. <\/p>\n

Many firms have historically overlooked the R&D Credit<\/a><\/strong> because they did not view their work as traditional research. In practice, firms that routinely engage in technical design and performance-driven problem solving typically generate qualifying activity. <\/p>\n

The credit applies annually and is claimed directly by the firm. A portion of qualified wages paid to engineers, designers, and technical staff can be recaptured through the credit, creating a recurring federal benefit tied directly to the firm\u2019s core operations. <\/p>\n

Unlike 179D, the R&D Credit is not dependent on public-sector allocations or construction start dates. It is embedded in the tax code as an ongoing incentive. <\/p>\n

As 179D phases out, the R&D Credit represents a more durable and repeatable strategy. <\/p>\n

\"\"<\/figure>\n

A Strategic Transition <\/h2>\n

The transition away from 179D should not be viewed simply as the loss of a deduction. It is an opportunity to reassess federal tax strategy more broadly. <\/p>\n

Architecture and engineering firms should consider:<\/strong> <\/p>\n
