Funding trigger
Does IRA clean-energy credits trigger Davis-Bacon prevailing wage?
Effectively yes, to earn the full credit. The IRA does not impose Davis-Bacon directly, but most clean-energy tax credits pay only one-fifth of the base rate unless the project meets prevailing wage and apprenticeship (PWA) requirements.
Short answer
Effectively yes, to earn the full credit. The IRA does not impose Davis-Bacon directly, but most clean-energy tax credits pay only one-fifth of the base rate unless the project meets prevailing wage and apprenticeship (PWA) requirements.
How the requirement attaches
For projects that began construction on or after January 29, 2023, the IRS/Treasury PWA rules require laborers and mechanics to be paid no less than the prevailing wages published by the Department of Labor for the locality, mirroring the Davis-Bacon wage-determination system. Meeting PWA multiplies the base credit (commonly 5x).
Bid-file implication
Price the labor at the DOL prevailing wage for the locality and keep certified payroll — the tax-credit economics usually make PWA compliance mandatory in practice, even on privately owned energy projects.

What happens when both federal and state prevailing wage apply?
When a project is covered by both the federal Davis-Bacon wage determination and a state prevailing wage schedule, the contractor generally must pay the higher of the two total hourly obligations for each classification.
Do I still need certified payroll?
Yes. Covered contractors and subcontractors must submit weekly certified payroll showing the classifications and rates paid.
