What Is Certified Payroll and Which Companies Must Use It?

Certified payroll is a weekly, signed wage report that every contractor and subcontractor on a federal or federally assisted construction contract worth more than $2,000 must submit to prove workers received the required prevailing wage. The filing obligation reaches the prime contractor, subcontractors at every tier, and business owners who perform covered work on the jobsite themselves. The $2,000 threshold comes from the Davis-Bacon Act and has not changed since 1931, which means nearly every federal construction contract is covered.¹

What the Report Actually Is

A certified payroll is a weekly statement listing every laborer and mechanic who worked on the covered project, the hours they worked, the classification they worked under, the wage and fringe benefits they received, and the deductions taken from their pay. The Copeland Act (40 U.S.C. § 3145) is the law that requires the weekly statement and makes it subject to the federal false-statements statute, 18 U.S.C. § 1001.²

What makes the payroll “certified” is the Statement of Compliance signed by a responsible company official. That statement certifies the payroll is accurate, that each worker received the full prevailing wage without unauthorized deductions, and that no portion of wages was kicked back to the employer or anyone else.³ It does not need to be notarized. It does need to be true: falsifying it is a federal crime punishable by a fine and up to five years in prison.⁴

The Department of Labor publishes Form WH-347 as a convenience, and most contracting agencies expect either that form or its electronic equivalent. Using WH-347 is technically optional; any format that captures all the required data elements can be used.³ Whichever format is chosen, each worker entry must include name and trade classification, a unique identifier (typically the last four digits of the Social Security Number, with full SSNs kept on file for inspection), daily and weekly hours split between straight time and overtime, the hourly rate and gross pay, the method of satisfying the fringe benefit obligation, itemized deductions, and net wages.⁵

Which Companies Must File

The trigger is a federal or District of Columbia construction contract exceeding $2,000 for construction, alteration, or repair of public buildings or public works, including painting and decorating.¹ Because the threshold is so low, direct federal construction work is effectively always covered.

Coverage does not stop at direct federal contracts. Dozens of “Related Acts” extend the same prevailing-wage and reporting obligations to projects that receive federal assistance, including federal-aid highway construction, public housing, and work financed by federal grants or loans.⁶ If the money on the project is traceable back to a federal source and the work is construction, the certified payroll obligation likely follows.

The obligation flows down the contracting chain. The prime contractor files its own weekly payroll and is responsible for collecting and submitting the payrolls of every subcontractor on the project.⁵ A subcontractor three tiers removed from the prime has the same filing duty as the general contractor holding the federal contract. A sole proprietor who takes a small piece of a covered project as a lower-tier sub is still on the hook.

One boundary worth flagging: purely state- or locally funded construction is not covered by Davis-Bacon. Roughly half the states have their own prevailing wage statutes, sometimes called “Little Davis-Bacon” laws, which impose similar certified payroll requirements but with different contract-value thresholds and sometimes longer retention rules. When a project draws both federal and state funds, both rule sets apply and the stricter one controls.

Which Workers Go on the Report

The report covers every “laborer or mechanic” on the project. That term reaches any worker whose duties are manual or physical, including those who use tools or perform trade work. Apprentices and helpers are included, along with watchpersons and guards on contracts subject to the Contract Work Hours and Safety Standards Act.⁷ Workers whose duties are primarily administrative, executive, or clerical are not covered.

Working forepersons complicate the picture. A foreperson who spends more than 20 percent of the workweek performing hands-on laborer or mechanic duties must be reported on the certified payroll for those hours.⁷ Owners who pick up tools on the site fall under the same rule. Title does not decide it; the work does.

Apprentices can be paid less than the full journeyworker rate only if they are individually registered in a program approved by the Department of Labor’s Office of Apprenticeship or a recognized State Apprenticeship Agency, are paid the percentage of the journeyworker rate specified by that program, and are working within the program’s allowable apprentice-to-journeyworker ratio, checked daily.⁸ On the certified payroll, each apprentice must be marked as “RA” rather than “J,” and current registration paperwork should be on hand. A worker listed as an apprentice without that documentation is treated as underpaid at the journeyworker rate.

Coverage also depends on where the work happens. Davis-Bacon reaches work at the “site of the work,” which includes the primary construction site, any secondary site where a significant portion of the project is built specifically for that contract, and adjacent support facilities like batch plants or tool yards dedicated to the project.⁹ A remote factory producing standard products for the general public is not a covered site, even if those products end up on a Davis-Bacon project.

When and How It Gets Filed

Certified payrolls are due weekly, within seven calendar days after the regular pay date for that payroll period.¹⁰ The recipient is usually a representative of the contracting agency at the jobsite; where there is no on-site representative, submission goes to the agency office. Many agencies now require electronic filing through platforms such as LCPtracker or Elation Systems, and the specific method should be confirmed with the contracting officer before the first payroll comes due.

Reports are numbered sequentially, starting with “1” for the first week of work. When no work is performed in a given week, a report marked “no work performed” still goes in so the numbering stays unbroken.¹¹ The final submission when the contract work wraps up should be marked as such. Gaps in numbering are a common trigger for compliance review.

Certified payroll records and their supporting documentation — time cards, canceled checks, fringe benefit payment receipts — must be kept for at least three years after the prime contract is completed and produced for inspection on request from the Department of Labor’s Wage and Hour Division.¹⁰ Some state prevailing wage laws stretch that to four years or more.

What Happens if a Filer Gets It Wrong

Late or incomplete submissions give the contracting agency authority to suspend progress payments on the entire contract until the violation is corrected, not just the portion tied to the missing payroll.¹² When workers have been underpaid, the agency can withhold accrued payments to cover back wages, interest, and monetary relief. It can do this on its own initiative and must do so when the Department of Labor requests it in writing.

The reach extends further for contractors with more than one federal project. The government can cross-withhold funds from any other federal or federally assisted contract held by the same prime, even if the violations happened on an unrelated job.¹³ The DOL’s claim to withheld funds takes priority over sureties, bankruptcy trustees, and assignees.

Contractors and subcontractors who show a disregard of their obligations to workers can be barred from all federal and federally assisted construction contracts for three years.¹⁴ Debarment is not reserved for outright fraud; a pattern of failing to pay correct rates or repeated payroll reporting failures can trigger it. The ban extends to any firm, corporation, partnership, or association in which the debarred contractor holds a substantial interest.

Signing a false Statement of Compliance is prosecutable under 18 U.S.C. § 1001, carrying a fine and up to five years of imprisonment.⁴ Criminal referrals are rare for first-time paperwork errors. Intentional underpayment schemes involving falsified payrolls do get prosecuted.

Mistakes That Most Often Draw Scrutiny

Most certified payroll problems trace back to sloppy processes rather than intentional fraud. A handful of errors show up over and over:

Listing a worker under a cheaper trade classification than the work actually performed. Auditors compare the classification on the payroll to the scope of work, and mismatches produce back-wage findings quickly.
Paying an apprentice rate to a worker without current registration in an approved program. Without the paperwork, the worker is owed the full journeyworker rate.
Missing the gap between the fringe benefit credit earned through a plan and the fringe rate on the wage determination. Any shortfall must be paid in cash, and contractors routinely leave it on the table.
Skipping “no work performed” submissions. The resulting gap in the sequential numbering is a common audit trigger.
Treating a worker as an independent contractor to keep them off the report. If they performed laborer or mechanic duties on a covered project, they belong on the certified payroll regardless of tax classification. The DOL looks at the economic reality of the relationship, not the label on the contract.

For a company new to federal work, the practical move is to build certified payroll into project setup from day one: verify the wage determination before bidding, assign someone to own the weekly filing, and treat the seven-day deadline as fixed. The contractors who run into serious trouble are almost always the ones who treated payroll reporting as back-office paperwork rather than a core project function.
