LIMBER Timber Act of 2026

The LIMBER Timber Act of 2026 creates three new federal tax credits to support the mass timber industry. It provides a 30% investment credit for businesses building mass timber manufacturing plants, a 50% credit for workforce training and hiring expenses in mass timber-related businesses (requiring at least 70% certified sustainable mass timber), and a $5 per square foot credit for constructing buildings with at least 50% of load-bearing components made of mass timber and 70% certified sustainable mass timber. These credits apply to manufacturers, construction contractors, and design firms working with mass timber - defined as engineered wood products like cross-laminated timber - and expire after December 31, 2030. The bill requires all credits to meet specific sustainability sourcing standards to qualify.
