Compliance

What is certified payroll in construction?

Certified payroll is the weekly payroll report, signed under a statement of compliance, that contractors and subcontractors submit on federally funded and prevailing wage jobs to prove each worker was paid the required wage and fringe benefits.

Certified payroll is a payroll record with a signature that carries legal weight. On jobs covered by the Davis-Bacon Act and related acts, every contractor and subcontractor must submit payroll information weekly, for each week covered work is performed. Each submission includes a signed Statement of Compliance saying the payroll is accurate and complete and that every laborer and mechanic got at least the required prevailing wage and fringe benefits.

The U.S. Department of Labor publishes WH-347 as the standard form. Using that exact form is optional, but submitting the same information weekly is not. Many state prevailing wage programs have their own certified payroll format and filing portal.

What certified payroll shows

  • Each worker's name and an identifying number, and the work classification from the wage determination.
  • Hours worked each day and total hours for the week, with overtime separated.
  • The rate paid, including cash fringe, and gross wages for the project and for all work that week.
  • Deductions and net pay.
  • How fringe benefits were provided: paid into approved plans, paid in cash, or a mix, as covered in fringe benefits.

How it works on a real job

Say an HVAC sub has four workers on a federally funded clinic. The wage determination lists sheet metal workers at a base rate plus a fringe rate. One worker spends Tuesday doing laborer work at a lower classification. The payroll must show the hours split by classification, and the sub needs time records that support the split. If the split is not documented, the worker is owed the higher rate for all hours.

The sub sends its signed payroll to the GC every week. The prime contractor is responsible for submitting payrolls for all its subcontractors to the federal agency, or, where the agency is not a party to the contract, to the owner or sponsor that keeps the records. Payroll records and certified payrolls must be kept for at least 3 years after all work on the prime contract is complete.

Common certified payroll errors

  1. Classifying workers by job title instead of the actual work performed.
  2. Paying the base rate but not the full fringe amount, in cash or into a plan.
  3. Taking fringe credit for a plan that does not qualify or is not funded as claimed.
  4. Missing weeks, including weeks with zero hours when the project requires a no-work report.
  5. Using apprentices who are not registered in an approved program, or exceeding the apprentice ratio.

Frequently asked questions

Who has to submit certified payroll?

Every contractor and subcontractor with laborers or mechanics on a covered federal or prevailing wage project. The prime contractor collects and submits subcontractor payrolls.

How long must certified payroll records be kept?

Under 29 CFR 5.5, at least 3 years after all work on the prime contract is completed. State programs may set their own periods.

Do state prevailing wage jobs require certified payroll?

Most state programs require it, often on their own form or through an online portal. Check the state agency for the format and deadline.
