179D Tax Deduction
Maximize Your 179D Tax Deduction
What is the 179D Tax Deduction?
The 179D tax deduction, also known as the Energy Efficient Commercial Buildings Deduction, incentivizes both commercial building owners and designers of public buildings to implement energy-efficient technologies. This incentive has been in effect since 2006 and was made permanent in 2020. With enhancements from the Inflation Reduction Act, the deduction now offers even greater financial benefits.
This deduction targets improvements in HVAC systems, lighting, and building envelopes, encouraging both commercial building owners and designers of public buildings to adopt sustainable practices. Eligible projects, including those involving government-owned buildings, non-profits, Indian tribal governments, or Alaska Native organizations, can receive deductions up to $5 per square foot. To qualify for the full deduction, projects must meet specific prevailing wage and apprenticeship requirements.
By taking advantage of the 179D deduction, eligible businesses can significantly reduce tax liabilities while contributing to a more sustainable future. Our expert team is here to guide you through the process and help maximize your benefits.
