This guide explains how certified payroll works in California, what information must be reported, and how contractors can avoid common penalties.
What Is Certified Payroll?
Certified payroll is a weekly payroll report submitted by contractors and subcontractors on public works projects. It certifies that workers are paid the correct prevailing wage, classified properly, and compensated according to California labor laws.
These reports are submitted to the California Department of Industrial Relations (DIR) through approved systems and become part of the project’s official compliance record.
