Certified Payroll in New Jersey

If you're a contractor or subcontractor on a New Jersey public works job, you have two obligations that run every week the crew is on site: pay every worker the prevailing rate for their craft and county, and prove it with a certified payroll record. New Jersey adds a step most states don't — you have to be registered as a public works contractor before you can even bid. This guide walks through who's covered, what to file and where, and how the state rules interact with the federal WH-347 when a project has federal money in it.

Who's covered: the New Jersey Prevailing Wage Act

New Jersey's requirements come from the New Jersey Prevailing Wage Act, administered by the New Jersey Department of Labor & Workforce Development (NJDOL). The Act covers construction-type work — building, altering, repairing, demolishing — performed under contract with a public body, once the contract value exceeds the statutory thresholds. The thresholds differ depending on the kind of public body involved and are adjusted over time, so don't assume a small job is exempt: verify the current thresholds with the NJDOL or the awarding public body before you price the work.

When a project is covered, every contractor and subcontractor on it must pay at least the prevailing rate the NJDOL has determined for each worker's craft and county. The classification on your payroll has to match the work actually performed — a worker doing two different crafts in one week is paid, and reported, at each rate for the hours in each craft.

Register before you bid

Under the Public Works Contractor Registration Act, contractors and subcontractors must hold a current NJDOL public works contractor registration before bidding on or performing covered public work. This is a real gate, not paperwork trivia: an unregistered contractor on a covered job faces penalties, and general contractors are expected to use registered subs. If you're new to New Jersey public work, start the registration through the NJDOL website well before bid day, and confirm the registration of every sub you bring on.

The weekly certified payroll record — and where it goes

Contractors and subcontractors on covered projects must keep accurate payroll records and submit certified payroll records to the public body or awarding authority that let the state verify prevailing wages were actually paid. The NJDOL publishes a certified payroll form for this — form MW-562 — which captures, for each worker and each week:

• Name and identifying information, and craft/classification
• Hours worked each day, split into straight time and overtime
• Hourly rate and fringe benefits paid (to plans or in cash)
• Gross pay, itemized deductions, and net pay
• A signed certification that the record is true and that workers were paid the required prevailing rates

Submission timing is tied to when wages are paid — the commonly cited rule is that the certified payroll is due within 10 days of paying the wages it covers. Contracts and awarding bodies can layer their own schedules and formats on top of that, so read your contract and confirm the exact cadence, recipient, and format with the awarding public body before your first payroll is due. Keep copies: the records are what protect you if a question comes up years later.

New Jersey vs. the federal WH-347: when both apply

A lot of New Jersey public work also carries federal money — road and transit projects, housing authority work, water infrastructure with federal grants. Federal funding triggers the Davis-Bacon Act, which brings its own wage determination and its own weekly certified payroll — the federal Form WH-347 (or an equivalent carrying the same data), submitted to the federal funding chain.

The two systems don't cancel each other out; both can apply at once. In practice that means:

• Pay the higher applicable rate. For each classification, compare the NJDOL rate and the federal wage determination rate and pay at least the higher total package.
• File what each side requires. The awarding body may want the state certified payroll while the federal side requires a WH-347. Ask your awarding body whether one submission satisfies both — many will tell you exactly what they accept.
• The data is the same either way. Names, classifications, daily hours, rates, fringes, gross, deductions, net, and a signed Statement of Compliance — the WH-347 dataset covers what New Jersey asks for, which is why one accurate weekly record can feed both filings.

Looking up New Jersey prevailing wage rates

The NJDOL publishes prevailing wage determinations by county and by craft, available through the nj.gov/labor site. Each determination lists the base hourly rate and the fringe benefit amount for a classification; the two together are the package you owe. Rates change as new determinations are issued, so always pull the determination that applies to your specific contract — the rate in effect for your project, not the newest rate you can find or one remembered from a past job. If a classification is ambiguous for the work your crew is doing, get the answer in writing from the NJDOL or the awarding body rather than guessing.

Fringe works the way it does under the federal rules: you can satisfy the fringe amount with contributions to bona-fide benefit plans, with cash in lieu of benefits, or a combination — but the total of cash wage plus benefits has to meet the full package, every hour. On overtime, the published schedules and your contract control the details; on federally funded work the Davis-Bacon rule applies, where the premium is 1.5× the base rate with fringe added at straight time — not 1.5× the whole package.

Common mistakes on NJ certified payroll

• Working unregistered. Bidding or starting work before the public works contractor registration is in hand — or using an unregistered sub.
• Wrong county or stale rates. Paying a rate from a different county or an outdated determination instead of the one tied to your contract.
• Misclassification. Reporting skilled work under a cheaper classification — the top enforcement target.
• Fringe shortfalls. Cash plus benefits coming in under the required package, which turns into back wages across every hour worked.
• Late or missing submissions. Missing the payment-tied deadline, or filing only the state record when the federal side also requires a WH-347.

The stakes are real: prevailing wage and registration violations can bring stop-work orders, civil penalties, and debarment from public work. The weekly report you sign is a legal attestation, so the math underneath it has to be right.

How Certiwage helps

Certiwage takes your crew's hours and the base and fringe rates off your New Jersey wage determination and generates a complete weekly certified payroll — daily hours, straight time and overtime, gross, deductions, and net, with the Statement of Compliance. It applies the correct overtime formula and checks your fringe package against the required rate so a shortfall is caught before you sign, not after an auditor finds it. Because the WH-347 dataset covers what New Jersey asks for, the same weekly record supports both a federal WH-347 filing and your state submission — you submit to the awarding body per your contract. Certiwage is a document-preparation tool, not legal advice, and is not affiliated with the NJDOL or any government agency, so always confirm the form, portal, and timing your awarding body requires. You can compare how neighboring states handle this in our New York guide or see the California DIR eCPR guide.

The quickest way to check whether your numbers hold up is to run one week through the free WH-347 builder — the fringe and overtime math is verified for you, no signup required.
