Understanding Certified Payroll Requirements for Construction Contractors

Certified payroll requirements ensure contractors working on government-funded construction projects submit weekly wage reports using Form WH-347 that verify workers receive prevailing wages on public works projects.

Federal construction projects offer lucrative opportunities, but they come with strict compliance requirements under prevailing wage laws. Understanding certified payroll requirements and maintaining accurate certified payroll records helps contractors protect their business from penalties, payment delays and complications with future federal work.

This guide breaks down exactly which companies must file, which workers are covered and how to stay compliant.

When Certified Payroll Is Required

Certified payroll requirements apply to any federally funded construction project under the Davis-Bacon Act. Contractors must file weekly reports within seven days after the regular payment date for each payroll period, even during weeks when no work occurs.

The requirement applies to projects funded entirely or partially by federal dollars. Even if federal money covers only 20% of project costs, that’s enough to trigger full Davis-Bacon compliance for everyone on the job.

Federal Requirements

Federal projects over $2,000 require certified payroll using Form WH-347. Records must be kept for three years after project completion.

Each project is assigned a wage determination by the Department of Labor that specifies the prevailing wage rates and fringe benefits for different worker classifications in the project’s geographic location. Contractors must use the correct wage determination to ensure compliance with wage requirements.

The requirement starts when work begins and continues through completion, including temporary shutdowns that require ‘no work’ reports.

State Requirements

State thresholds and requirements vary significantly.

For example, California requires prevailing wages at $1,000 and mandates online submission through the Department of Industrial Relations system. However, Illinois and New York have no threshold — all public work requires prevailing wages. Wyoming’s threshold is $100,000.

Contractors working across state lines must track different requirements for each jurisdiction.

Which Contractors Must File Certified Payroll

Every construction company performing work on covered federal projects must submit certified payroll reports using Form WH-347. 

These reports are usually handled by the general contractor and head subcontractor of the construction companies.

General contractors own the compliance chain and must ensure every subcontractor company submits their reports on time.

It should be noted that these reports cover only their own laborers and mechanics who perform covered work on-site — not every employee on the company payroll.

Which Workers Must Be Reported

Contractors must report all laborers and mechanics performing construction work on-site. Covered workers include carpenters, electricians, plumbers, masons, painters, roofers, ironworkers, laborers, operators and truck drivers who spend significant time on-site.

Form WH-347 requires contractors to document each worker’s job classification based on the actual work performed, along with hours worked and wages paid for each classification. Proper job classification is critical because prevailing wage rates vary by classification and location.

Workers Who Don’t Need to Be Reported

Administrative, executive and clerical workers are not covered by Davis-Bacon prevailing wage requirements. Exempt roles typically include project managers, estimators, office staff, bookkeepers and superintendents who don’t perform manual work.

Coverage depends on actual duties performed, not job titles.

A superintendent who occasionally uses tools must be reported for those hours at the prevailing wage. Material suppliers delivering products without installation don’t need to be reported, but drivers who stay on-site helping unload for several hours must be included.

Apprentice and Subcontractor Rules

Contractors can pay apprentices at reduced percentages of the prevailing wage base hourly rate when they’re registered in Department of Labor-approved apprenticeship programs.

This means apprentices receive a percentage of the journeyman prevailing wage for their craft (such as 60% for a second-year apprentice) while still receiving full prevailing wage fringe benefits.

The Department of Labor maintains approved programs through the Office of Apprenticeship. Each approved program specifies wage schedule percentages for different apprenticeship levels.

Registration must be active, current and match the craft on payroll reports. Simply calling workers “apprentices” without proper DOL program registration isn’t sufficient. These workers must be paid the full journeyman prevailing wage.

Subcontractor Compliance

Subcontractors face identical certified payroll obligations as prime contractors. They submit weekly reports through the general contractor, who is responsible for ensuring compliance.

Prime contractors face strict liability for subcontractor violations under Davis-Bacon regulations. This means general contractors are financially responsible for wage violations by any subcontractor in the chain, even if the prime contractor didn’t know about the violations.

The Department of Labor’s 2023 Final Rule strengthened this liability by explicitly stating that prime contractors and upper-tier subcontractors are responsible for back wages when lower-tier subs violate prevailing wage requirements.

The rule also expanded potential debarment to prime contractors who fail to take responsibility for ensuring subcontractor compliance. This creates significant oversight obligations that require thorough monitoring of every contractor in the chain.

How Construction Payroll Services Help With Compliance

Managing certified payroll manually creates significant compliance risks for contractors working on federal projects.

Weekly reporting deadlines, complex prevailing wage calculations, worker classification requirements and subcontractor oversight all demand specialized expertise and consistent attention.

Construction payroll services designed for Davis-Bacon compliance automate the most error-prone aspects of certified payroll reporting.

These platforms typically handle Form WH-347 preparation, track current prevailing wage rates by classification and location, calculate fringe benefit obligations and maintain the required three-year documentation.
