Certified Payroll in Construction: A Complete Guide

Certified payroll is a weekly payroll report that contractors and subcontractors must submit on federally funded construction projects to prove they’re paying workers the prevailing wage rates set by the U.S. Department of Labor (DOL). Required under the Davis-Bacon Act for projects exceeding $2,000, these reports use Form WH-347 and include each worker’s name, classification, hours, wage rate, and deductions. 

Missing or late submissions can trigger contract fund withholding, project debarment for up to three years, and payment freezes that cascade from the prime contractor through every subcontractor on the job. On a $15M public school project with eight subs, one late report from one electrical contractor can hold the entire billing cycle. For contractors managing prevailing wage compliance across multiple projects, platforms like Built track compliance documents, including certified payroll, and enforce collection before payments release.

What Is Certified Payroll?

Certified payroll is a federally mandated report that proves construction workers on public projects are being paid the correct prevailing wage. The report is filed weekly on Form WH-347, a standardized template published by the DOL. It covers every worker on a covered project, documenting their classification, hours, pay rate, deductions, and net wages.

The requirement traces back to the Davis-Bacon Act of 1931, which Congress passed to prevent contractors from undercutting local wages on federal construction projects. The law applies to all federal contracts exceeding $2,000 for construction, alteration, or repair of public buildings and works. Related acts, including the Copeland Anti-Kickback Act, added criminal penalties for falsifying these reports or making unauthorized deductions from worker pay.

One important distinction

Certified payroll refers to the reporting obligation. It isn’t the same as the Certified Payroll Professional (CPP) credential, which is an HR certification from the American Payroll Association. The two share a name but serve different purposes. When construction professionals talk about certified payroll, they mean the weekly compliance report filed on prevailing wage projects.

Every prime contractor on a covered project is responsible for collecting certified payroll reports from every subcontractor working on that project. The reports are part of a compliance chain tied directly to whether the project gets paid.

When Is Certified Payroll Required?

The federal threshold is straightforward. Any construction contract exceeding $2,000 for work on public buildings or public works funded in whole or in part by federal money triggers the Davis-Bacon Act. Once triggered, certified payroll reports must be filed weekly for the duration of the project.

Filing doesn’t stop when work pauses

Contractors must file weekly certified payroll reports even during weeks when no work is performed on the project. A “no work” report is still required. Missing a week creates a gap in the compliance record, and that gap can hold up the entire payment chain.

Who files

The prime contractor carries the legal responsibility. That doesn’t mean the prime does all the reporting. Every subcontractor on the project files their own certified payroll for their workers. However, the prime must collect, review, and submit all reports as part of the overall compliance package. If a sub doesn’t file, the prime is the one who answers for it.

Covered workers

Certified payroll applies to laborers and mechanics who perform work on the physical site of the project. This includes apprentices and trainees. It doesn’t apply to salaried executive, administrative, or professional employees under the Fair Labor Standards Act exemptions.

The scale problem is real

Picture a $15M public school project with eight subs across five trades. Each sub has different worker classifications and wage rates. Every week, every sub must file. The electrical contractor has journeymen and apprentices at different rates. The concrete crew has operators and laborers. The HVAC sub brought in workers from two different locals with different fringe benefit calculations.

One missing report from one sub, and the prime contractor can’t submit a complete compliance package. The draw gets held. The billing cycle stalls.

The Bipartisan Infrastructure Law expanded the number of federally funded projects significantly, which means more projects now fall under Davis-Bacon requirements. GCs bidding on infrastructure work, transportation projects, and public facility construction should assume certified payroll applies until confirmed otherwise.

What Information Goes on a Certified Payroll Report?

Form WH-347 collects nine categories of information for each worker on a covered project. The form is structured to make prevailing wage verification possible at a glance, but completing it correctly requires attention to classification details and fringe benefit calculations.

Every certified payroll report must include the following:

1. Full name and identifying number: Each worker’s name and the last four digits of their Social Security number (or an alternative identifying number assigned by the contractor).
2. Work classification: The specific trade classification for each worker (electrician, carpenter, laborer, operator, etc.) as defined in the applicable wage determination.
3. Hours worked daily: Straight time and overtime hours broken out by day for the reporting week.
4. Total hours: Combined straight time and overtime hours for the week.
5. Rate of pay: The hourly base rate plus fringe benefit rate. The combined rate must meet or exceed the prevailing wage for that classification.
6. Gross amount earned: Total wages before deductions.
7. All deductions and total deductions: Federal and state taxes, FICA, union dues, and any other authorized deductions. Unauthorized deductions violate the Copeland Anti-Kickback Act.
8. Net wages paid: Take-home pay after all deductions.
9. Statement of compliance: A signed certification by the contractor or authorized agent confirming the report is accurate and all workers were paid the applicable prevailing wage.

The DOL provides Form WH-347 as an optional but widely used template. Some agencies and states require their own versions, but the data fields are consistent.

Prevailing wage rate determinations

Wage rates aren’t universal. The DOL publishes two types of determinations. General wage determinations are area-based and apply to a geographic region. Project wage determinations are specific to a single project and expire 180 days after issuance under 29 CFR 1.6(a)(3)(i) if not incorporated into a contract during that period. Contractors must use the correct determination for their project, and they need to verify it hasn’t been superseded before filing.

Fringe benefits add complexity

The prevailing wage includes a base hourly rate plus a fringe benefit component. Contractors can pay fringe benefits as cash, contribute to bona fide benefit plans, or use a combination of both. The calculation method must be documented on the certified payroll report. Getting this wrong is one of the most common errors the DOL finds during audits.

How Certified Payroll Affects the Payment Chain

Most contractors think of certified payroll as a compliance form. It’s actually a payment gatekeeper.

Your compliance system protects your payment cycle. When a sub doesn’t file certified payroll on time, the prime contractor can’t submit a complete compliance package to the project owner or agency. Without a complete package, the draw gets held. The owner can’t release funds. Every sub downstream waits, including the ones who filed their reports on time and did everything right.

The dollar impact

70% of contractors regularly face delayed payments. Subs inflate bids an average of 8% to protect against slow payment cycles. When compliance documents are missing, billing cycles get delayed two to four weeks. On a prevailing wage project, those numbers translate directly into cash flow pressure on every contractor in the chain.

A real scenario

On a prevailing wage project with 12 subs, one missing certified payroll report from a framing crew can freeze the entire billing cycle for the month. The GC can’t submit the compliance package. The owner holds the draw. The mechanical contractor who filed on time, the electrician who filed on time, the site work crew who filed on time, all of them wait, not because they didn’t comply but because one sub didn’t.

The sub-tier perspective

This is where certified payroll compliance becomes a relationship issue, not just a regulatory one. A sub who does their work, files their report, and waits 30 extra days to get paid because another sub didn’t file has every reason to question whether they want to bid the next project with that GC.

The best subs have options. They’ll take work from GCs who pay on time. A GC who can’t manage certified payroll collection across their subs is risking their trade partner relationships, which means risking their ability to staff the next project.

Certified payroll is about keeping the documents required with a payment application complete so that money keeps moving.

Penalties for Certified Payroll Violations

The consequences for certified payroll violations go beyond paperwork. They hit the project, the contractor’s reputation, and in some cases, the contractor’s freedom.

Contract fund withholding

The contracting agency can withhold funds from progress payments to cover back wages owed to underpaid workers. The withholding continues until the contractor can demonstrate full payment at the correct prevailing wage rate.

Contract termination

The government can terminate a contract for cause if a contractor fails to comply with Davis-Bacon requirements. The contractor then becomes liable for any additional costs the government incurs to complete the project with a replacement contractor.

Debarment

Contractors and subcontractors found in violation can be debarred from all federal contracts for up to three years. Debarment applies to the company and its responsible officers. For a firm that depends on public work, three years without federal contracts can be existential.

Criminal penalties

The Copeland Anti-Kickback Act makes it a federal crime to falsify certified payroll reports. Penalties include fines up to $5,000 and imprisonment. Requiring workers to kick back a portion of their wages is a separate criminal offense under the same statute.

State-level enforcement

Many states have their own prevailing wage enforcement mechanisms with independent penalty structures. In California, penalties for failing to provide certified payroll records can reach $100 per worker per calendar day under Labor Code Section 1776. Other states impose stop-work orders, license suspensions, or additional withholding requirements.

The DOL Wage and Hour Division actively investigates and enforces Davis-Bacon compliance. The consequences cascade through the project in the form of frozen payments, delayed schedules, and damaged contractor relationships.

State Prevailing Wage Laws and Certified Payroll

Federal certified payroll requirements are just the baseline. Many states have enacted their own prevailing wage laws, often called “Little Davis-Bacon” acts, that impose additional or different requirements on state-funded and municipally funded construction projects.

Key differences from federal requirements

State laws often set lower contract thresholds than the federal $2,000 minimum. Some states apply prevailing wage requirements to all public construction regardless of dollar amount. The project scope is broader too. While the federal Davis-Bacon Act covers only federally funded projects, state laws typically cover projects funded by state, county, and municipal dollars.

Wage determination methods also vary. Some states use DOL data as a starting point. Others conduct independent wage surveys or rely on collective bargaining agreement rates.

States with notable certified payroll programs

California has one of the most stringent programs in the country. Labor Code Section 1776 requires contractors to maintain certified payroll records and submit them to the Department of Industrial Relations (DIR) electronically. The state enforces penalties at the rate described above and requires electronic filing through the DIR’s online system.

New York’s Labor Law Article 8 covers public works projects and requires certified payroll submissions with different classification structures than the federal system. Massachusetts, New Jersey, and Illinois each have their own prevailing wage acts with distinct filing timelines, wage determination processes, and penalty structures.

The multi-state challenge

GCs working across state lines face a compliance patchwork. A contractor with prevailing wage projects in California, New York, and Illinois is managing three different filing systems, three different wage determination sources, and three different penalty frameworks simultaneously.

The certified payroll report itself might look similar across jurisdictions, but the rules governing when it’s required, how it’s filed, and what happens when it’s wrong vary significantly.

Certified payroll requirements vary by state. Some states have their own prevailing wage laws with different thresholds and filing requirements. Consult legal counsel for project-specific guidance.

How Built Helps Contractors Stay Compliant

Managing certified payroll across multiple projects with dozens of subs is an operational burden that scales with every new contract. Built’s construction payment management platform addresses this by making compliance a prerequisite for payment, not an afterthought.

Automated document collection

Built tracks every required compliance document per project, including certified payroll reports, lien waivers, insurance certificates, and safety documentation. Its status dashboards show which subs have submitted and which haven’t, across every active project, in one view. Expiration reminders go out automatically so the GC’s team isn’t chasing documents manually.

Compliance enforced before payment releases

The payment clock doesn’t start until the compliance checklist is complete. If a sub hasn’t submitted their certified payroll report, the system flags it before the GC submits the pay application. The compliance gap gets caught at the source, not after the draw is already in review.

What contractors say

Waltz Construction saw immediate results: “Before implementing Built, we were spending 1-2 hours tracking down compliance documentation and cutting checks.” Rod Heisler Construction reported a similar shift: “Not only has Built freed up a lot of my time, it’s also getting us paid a lot quicker from our clients.”

For GCs managing prevailing wage compliance on multiple projects, the choice is between a system that enforces compliance before payments move and a process that discovers gaps after the billing cycle is already delayed.

Certified Payroll FAQs

What is certified payroll in construction?

Certified payroll is a weekly report that contractors and subcontractors file on federally funded construction projects to verify that workers are being paid the prevailing wage. The report uses Form WH-347 and documents each worker’s name, trade classification, hours worked, pay rate, deductions, and net wages. It includes a signed statement of compliance certifying accuracy. The requirement comes from the Davis-Bacon Act, which applies to federal construction contracts exceeding $2,000.

When is certified payroll required?

Certified payroll is required on any construction project funded in whole or in part by the federal government where the contract exceeds $2,000. Many states also require certified payroll on state-funded and municipally funded projects under their own prevailing wage laws, often at lower thresholds. Reports must be filed weekly, even during weeks when no work is performed on the project.

Who is responsible for filing certified payroll?

Each contractor and subcontractor files certified payroll for their own workers. However, the prime contractor carries the overall legal responsibility. The prime must collect, review, and maintain certified payroll reports from every sub working on the project. If a sub fails to file, the prime contractor is accountable for the compliance gap.

What happens if you don’t submit certified payroll on time?

Late or missing certified payroll reports can trigger contract fund withholding, where the agency holds progress payments until the contractor demonstrates compliance. Repeated or willful violations can lead to contract termination, debarment from federal contracts for up to three years, and criminal penalties under the Copeland Anti-Kickback Act. On the project level, a missing report can freeze the entire billing cycle for all contractors.

What is the difference between prevailing wage and certified payroll?

Prevailing wage is the hourly pay rate (base plus fringe benefits) that the DOL determines workers must earn on covered construction projects. Certified payroll is the reporting mechanism that proves those wages were actually paid. The prevailing wage sets the standard. The certified payroll report is the weekly documentation proving the contractor met that standard.
