Is meeting the Prevailing Wage and Apprenticeship requirements essential for securing the maximum §179D tax deduction? Yes, meeting the Prevailing Wage and Apprenticeship requirements is central to unlocking the top-tier §179D deduction amounts (the $2.50 to $5 per square foot range) for projects placed in service after 2022, per recent IRS guidance under the Inflation Reduction Act. Establishing these labor compliance measures at the onset of construction is essential, as the deduction amount scales significantly based on meeting these enhanced labor standards.
The Prevailing Wage requirement ensures that every laborer and mechanic on the project—including subcontractors—is paid at least the local prevailing wage rate. The Apprenticeship rules, applicable to commercial projects only, require a rising percentage (at least 15% starting in 2024) of total labor hours to be performed by qualified apprentices under a registered program. Consistent documentation, maintained from day one, is crucial for proving compliance in case of an audit.
