Certified Payroll: What It Is and How To Keep Your Business Compliant

If your business works on federally funded construction projects, certified payroll reporting is a non-negotiable weekly requirement. Missed submissions, inaccurate records, or misclassified workers can result in penalties, back wage liability, or disqualification from future government contracts.

Without a consistent process in place, it’s easy to get bogged down in the complexities of certified payroll reporting. Knowing when certified payroll applies, what should be included, and how to ensure accurate, timely submission can help protect your business from compliance risk.

What Is Certified Payroll Reporting?

Certified payroll is a reporting obligation for contractors and subcontractors working on federally funded public works projects under the Davis-Bacon and Related Acts. It ensures that all workers are paid fairly in accordance with local prevailing wages and benefits for similar work in the area. The report documents wage and payment information for covered workers and provides a paper trail agencies use to verify compliance with prevailing wage rules.

Certified payroll is completely separate from the Certified Payroll Professional (CPP) designation, which is a credential for payroll practitioners.

When Is Certified Payroll Required for Public Works Projects?

The Davis-Bacon and Related Acts require certified payroll reporting when a contractor or subcontractor works on a federally funded public works project with a contract value that exceeds $2,000. This includes construction, alteration, or repair of public buildings and infrastructure such as bridges, railways, schools, government buildings, power lines, and roads. Both the primary contractor and any subcontractors must submit weekly certified payroll reports for the duration of their contract.

States may also require certified payroll for state-funded projects. Requirements vary by jurisdiction, so contractors working on state or municipal projects should verify what applies based on the funding source, project type, and contract terms before work begins.

For example, a general contractor building a new public school for a local district that receives federal funding would need to submit weekly certified payroll reports documenting worker classifications, hours worked, and wages paid.

What Information Does a Certified Payroll Report Include?

A certified payroll report captures pay and workforce data for every covered worker on the project during that reporting week. The specific details required can vary depending on the agency, funding source, or jurisdiction, but most reports follow the structure of Form WH-347. Worker information is typically organized into three main categories:

Worker Details

Each worker on the project must be individually identified and correctly classified. The information in this section ties wages to the right person and the right prevailing wage rate.

• Employee Name and Identifying Information: Form WH-347 requires the last four digits of the employee's Social Security number.
• Job Classification: This determines the applicable prevailing wage rate for that worker.
• Work Status: State both the type of laborer (journeyman, apprentice/trainee, laborer, or foreman) and employee classification (W-2 employee or 1099 contractor).

Pay Details

Understanding certified payroll reporting requirements starts with knowing what pay data must be captured for each worker, including hours worked, applicable wage rates, and deductions.

• Hours Worked: Daily hours and total hours for the week, tracked by project.
• Pay Rates: Prevailing wage rates for both regular hours and overtime.
• Gross Wages: Total wages earned for the reporting period.
• Itemized Deductions: Taxes, benefit contributions, and any other withholdings.
• Net Wages: Total take home wages for the individual.

Compliance Details

Beyond wages, the report must capture fringe benefits, project information, and a signed statement confirming the report is accurate and complete.

• Fringe Benefits Provided: Direct payments or contributions to an approved benefit plan, plus the hourly value of those benefits.
• Project Information: Project name, location, and contract number.
• Contractor or Subcontractor Name and Address: Identifying information for all contractors working on the project.
• Statement of Compliance: A signed verification that the report is accurate and complete.

How To Stay Audit-Ready With Certified Payroll Reporting

Accurate certified payroll reports require a reliable internal process that captures the right job data, employee information, and wages. Accurate recordkeeping also keeps you audit-ready, so you can respond quickly if a contracting agency or the DOL requests documentation.

Here’s a practical example of how to structure a payroll reporting process that documents the information you need before, during, and after your payroll run:

Before Payroll Runs

Getting classifications and pay rates right before payroll runs prevents errors that are much harder to correct after the fact.

• Confirm Job Classifications: Confirm that all workers are classified correctly and that classifications match the prevailing wage determination in the contract.
• Verify Pay Rates: Compare pay rates to the wage schedule and confirm accuracy before the first paycheck goes out. Check prevailing wage details again whenever workers change roles or new subcontractors join the project.
• Document Labor Costs: Include pay rates, fringe benefits, deductions, and reimbursements.
• Track Hours by Project: Certified payroll reports require project-specific time data, so record hours separately for workers splitting time across jobs.

During Payroll Processing

As you process payroll for the week, capture the specific data the certified payroll report will need, including hours, deductions, and fringe benefits for every covered worker.

• Record Weekly Hours: Capture regular and overtime hours for each covered worker for the reporting week.
• Document Deductions and Fringe Benefits: Enter all deductions and fringe benefit contributions. Fringe benefits paid in cash must be documented at the hourly rate, while benefits provided through a plan need supporting plan documentation on file.
• Capture Multi-Jurisdiction Payroll: If an employee works in a different location from where they live or if you employ workers across state lines, you will need to document jobsite locations, prevailing wages, and tax withholdings for each jurisdiction.

After Payroll

Once payroll is processed, complete and submit the certified payroll report by the required deadline, including weeks when no work was performed.

• Complete the Certified Payroll Report: Use Form WH-347 or the agency's required equivalent to document details for every worker on the project.
• Review Details: Confirm accuracy of job classifications, hours, pay rates, fringe benefits, and deductions.
• Sign the Statement of Compliance: The person responsible for paying workers (typically the contractor or subcontractor) must sign a statement of compliance with Davis-Bacon laws.
• Submit the Form: Submit by the deadline specified in the contract through the required channel, such as a federal agency portal, a state system or portal, or a direct submission to the contracting officer.
• File Even for Weeks You Don’t Work: If no work is performed during a given week, you should still file a "no work" report to the appropriate agency in most cases.

Recordkeeping

Submitting the report is only part of the obligation. Maintaining the supporting documentation on file is what keeps you protected during an audit.

• Keep Records on File: Davis-Bacon regulations require contractors to maintain certified payroll records and documentation for a minimum of three years after the project is complete. This includes payroll records, time sheets, wage determinations, benefit plan documentation, and copies of each submitted report. State prevailing wage laws may have different retention periods, so verify requirements based on the jurisdiction and funding source.
• Maintain Supporting Documentation: Keep supporting documentation that backs up the information in each report. During an audit, these records can clear up any questions about classifications or wage rates.

Ownership and Accountability

Certified payroll compliance doesn’t happen by default. Assigning clear internal ownership ensures the process stays on track from week to week, especially on longer projects.

• Assign Responsibility: Assign internal responsibility for each step, including who prepares the report, who reviews it, who signs the Statement of Compliance, and who maintains the filing system.
• Schedule Internal Reviews: On longer projects, schedule periodic internal reviews to check for classification accuracy, hours discrepancies, or missing subcontractor reports before they become compliance issues.

How Paychex Supports Certified Payroll Reporting Workflows

Certified payroll reporting is only as accurate as the payroll data behind it. Wage errors, missing hours, or inconsistent deduction records create reporting problems that are difficult to correct after the fact. Paychex provides the infrastructure that ensures payroll accuracy and supports consistent reporting every week, including:

• Payroll Services: Paychex payroll services support the underlying data that certified payroll reporting depends on, including payroll processing, wage and hours tracking, deduction management, and fringe benefit documentation. For example:
• Time and Attendance: Paychex time and attendance tools help contractors track hours accurately by employee. This is essential for audit compliance, especially when workers are split across multiple jobs or project phases.
• Reporting: Reporting workflows help contractors create consistent reports with confidence, while maintaining accurate records and visibility.

For example, one business owner worked with Paychex to manage complex payroll processing and tax remittance across different counties, towns, prevailing rates, and laws, ensuring accuracy for certified payroll reporting. By handing off payroll processing to Paychex, the business owner reduced payroll to a single seven-minute call each week — saving four hours — and could suspend payroll during the off-season with just one quick call.
