But with the recent legislative change under the <strong><a href=\"https:\/\/leyton.com\/us\/insights\/articles\/obbb-tax-reform-what-it-really-means-for-businesses\/\">OBBBA<\/a><\/strong>, the clock is now officially ticking: <strong>projects that begin construction after June 30, 2026 will no longer qualify for 179D at all<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In practical terms, the incentive is entering its final stage, and the window to qualify is rapidly closing.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Updated 2026 Inflation-adjusted 179D Values<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For taxable years beginning in 2026:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Standard (non-PWA) pathway:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Base value:<\/strong> $0.59\/ft\u00b2<\/li>\n<li><strong>Maximum: <\/strong>$1.19\/ft\u00b2<\/li>\n<li><strong>Increment:<\/strong> +$0.02\/ft\u00b2 for every percentage point above 25% energy savings<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>PWA (Prevailing Wage + Apprenticeship) enhanced pathway:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Base value:<\/strong> $2.97\/ft\u00b2<\/li>\n<li><strong>Maximum: <\/strong>$5.94\/ft\u00b2<\/li>\n<li><strong>Increment:<\/strong> +$0.12\/ft\u00b2 for every percentage point above 25% savings<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">These increases reflect the IRS\u2019s annual inflation adjustment to ensure the deduction remains aligned construction cost escalation and the broader economic environment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why These 179D Amounts Increased: Inflation Adjustment Logic<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The annual adjustment is driven by several inflation-linked factors built into the Inflation Reduction Act, including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Annual construction cost escalation<\/li>\n<li>Labor and materials inflation<\/li>\n<li>Market-based valuation of deeper energy savings<\/li>\n<li>Federal wage provisions tied to PWA compliance<\/li>\n<li>Bureau of Labor Statistics published inflation indices<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">These mechanisms ensure that \u00a7179D continues to offer meaningful financial value especially on large commercial, institutional, and multifamily projects.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">\u00a7179D Ends for Projects Beginning Construction After June 30, 2026<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Section 70507 of the OBBBA establishes a firm cutoff: \u00a7179D is terminated for any property that begins construction after June 30, 2026.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What This Means for Eligibility:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Projects that begin construction on or before June 30, 2026 remain fully eligible for \u00a7179D.<\/li>\n<li>Projects beginning July 1, 2026 or later will not qualify, regardless of energy performance, system design, or whether they meet all Prevailing Wage + Apprenticeship (PWA) requirements<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Why This Deadline Is Critical for Your Pipeline:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Starting construction on or before the deadline secures access to the 2026 \u00a7179D deduction values.<\/li>\n<li>Starting construction after the deadline eliminates the incentive entirely<\/li>\n<li>Missing this cut-off could result in the loss of up to $5.94 per square foot in potential tax deductions under the PWA-enhanced pathway.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">For many large developments, this translates to millions in forfeited deductions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">PWA (Prevailing Wage + Apprenticeship) Compliance &amp;
