Quick answer
At a glance
Certified payroll is the weekly payroll documentation contractors use on many Davis-Bacon, federally assisted, and state public works projects to show worker classifications, hours, rates, fringe benefits, deductions, and required certifications. Contractors should verify the active solicitation, wage determination, DOL WH-347 guidance, 29 CFR requirements, and any state reporting system before bidding.
AI summary
Key takeaways
- DOL Form WH-347 is an optional certified payroll form commonly used for Davis-Bacon and Related Acts work, but agencies may accept equivalent formats when they contain the required information and certification.
- Certified payroll is tied to weekly payroll records, worker classifications, wage determinations, fringe benefits, deductions, and a signed Statement of Compliance.
- State public works programs can add their own electronic reporting systems and instructions.

What Certified Payroll Usually Requires
Certified payroll requirements vary by project, but a review file usually needs:
- Project and contract identifiers.
- Payroll period and sequential payroll number where required.
- Worker names or permitted worker identifiers.
- Work classifications used on the project.
- Daily and weekly hours.
- Base hourly rate and overtime where applicable.
- Fringe benefit treatment.
- Gross wages, deductions, and net wages.
- Apprentices, trainees, helpers, and owner-operators reviewed against the governing rules.
- A signed Statement of Compliance or required certification.
- Subcontractor payroll collection and review workflow.
Do not copy classifications from a prior job without checking the current wage determination and scope.
Bid Setup Checklist
| Area | Bid review question |
|---|---|
| Coverage | Does the solicitation, funding source, or state public works rule require certified payroll? |
| Wage source | Which wage determination or state rate source controls the estimate? |
| Classifications | Which labor classifications match the work actually being performed? |
| Fringes | Are fringe benefits paid in cash, bona fide plans, or another approved structure? |
| Submission | Is WH-347 accepted, or is a specific portal or format required? |
| Certification | Who signs the Statement of Compliance or equivalent certification? |
| Subcontractors | How will lower-tier payrolls be collected, checked, and corrected? |
| Records | How will payroll records, source documents, and corrections be retained? |
This checklist belongs in estimating and bid review, not only in payroll after award.
Common Certified Payroll Mistakes
Avoid these mistakes:
- Treating certified payroll as a back-office task that can wait until after award.
- Pricing labor without the current wage determination.
- Using the wrong classification for mixed work.
- Ignoring fringe benefit treatment when comparing labor cost.
- Forgetting apprentice or trainee documentation.
- Assuming WH-347 is the only accepted format without checking agency instructions.
- Missing state electronic reporting requirements.
- Failing to collect lower-tier subcontractor payrolls in time for prime submission.
- Submitting weekly payroll without a signed Statement of Compliance or equivalent certification.
Each one can create bid, payment, compliance, or audit risk.
Federal vs State Reporting
Federal Davis-Bacon work and state public works reporting can overlap, but they are not always the same workflow. A contractor may need to satisfy federal wage determination and certified payroll requirements while also using a state reporting portal or following agency-specific instructions.
California is a useful example: DIR's public works pages describe certified payroll reporting through its Public Works Website Services for many public works projects. Other states and agencies can use different systems.
For each project, confirm:
- Whether the project is federal, federally assisted, state, local, or mixed funding.
- Whether the owner, agency, or labor compliance program requires a specific portal.
- Whether the prime contractor must review subcontractor payroll before submission.
- Whether the contract adds certified payroll timing or correction rules.
