What Does Certified Payroll Mean for Contractors?

Certified payroll is a weekly report that contractors and subcontractors on federally funded construction projects file to prove every worker on the job was paid at least the prevailing wage for their trade. It is required on federal contracts over $2,000 under the Davis-Bacon Act, and on state, local, or private projects that receive federal grants, loans, or loan guarantees through what are called “Related Acts.”¹ The Copeland Anti-Kickback Act is the specific law that requires the weekly filing and prohibits pressuring workers to return any part of their wages.² Many states impose parallel obligations on their own public works.

The word “certified” matters. Each report is submitted under a signed Statement of Compliance, and knowingly submitting false information is a federal crime.

Who Files, and How Often

Every prime contractor and every tier of subcontractor on a covered project files certified payroll. There is no separate size threshold once the contract clears the $2,000 Davis-Bacon trigger. A solo electrical subcontractor filing for themselves has the same obligation as a general with 200 workers on site.

The report covers all laborers and mechanics working at the job site, including tradespeople, equipment operators, and site guards. Reports are due weekly, covering the preceding payroll period, and must run continuously from the first week of on-site work until the project is finished.³ The prime contractor is responsible for making sure every subcontractor’s reports actually get submitted, which is why most generals build submission deadlines into their subcontract agreements.

Missed weeks are not something you clean up quietly later. Contracting agencies track submission gaps, and a pattern of late filings can prompt an investigation even when the underlying wages were correct.

What Goes on the Report

The standard form is WH-347, “Payroll (For Contractors).” Using that specific form is optional, but any alternative format must carry identical information.⁴ For each worker on site during the reporting period, the report must show:

Full name and an individual identifier, typically the last four digits of the Social Security number. Full Social Security numbers must not be included.
Work classification matching a trade listed in the contract’s wage determination (for example, “Carpenter” or “Electrician”).
Hours worked each day and the weekly total, with straight time and overtime broken out separately.
Hourly cash rate and fringe benefit rate listed separately, so an auditor can confirm the combined total meets the prevailing wage.
Gross wages before deductions.
Every deduction itemized, including federal and state taxes, FICA, and any voluntary withholdings the worker authorized.
Net pay actually received.

The detail is not busywork. A reviewer traces the wage determination rate through the hourly breakdown, across the hours worked, to gross pay, and then confirms the deductions are legitimate. Any inconsistency in that chain gets flagged.

The Statement of Compliance

Each weekly payroll must be accompanied by a signed Statement of Compliance, which appears on the second page of Form WH-347.³ The signer attests that the payroll data is accurate, that every worker was paid at least the prevailing wage, and that no one was forced to return any portion of their pay.

The signature must come from someone with actual knowledge of the payroll facts, whether a company officer, the payroll manager, or another authorized employee who supervises wage payments. Handwritten and legally valid electronic signatures are both acceptable.³

Do not treat that signature as a formality. Knowingly submitting false information on a certified payroll report is a federal crime under 18 U.S.C. § 1001, carrying up to five years in prison.⁵ Even where a misstatement was unintentional, the contractor is still liable for any resulting wage underpayments.

How Prevailing Wages Work

The prevailing wage is not a single number. It is a basic hourly cash rate plus a separate fringe benefit rate, both specific to the worker’s trade and to the geographic area of the project. The Department of Labor sets these rates through wage surveys and publishes them in a “wage determination” that is incorporated into the contract before bidding. Rates vary sharply by trade and location; a carpenter’s rate in a major metro will not resemble the rate in a rural county nearby.

The fringe portion gives contractors some flexibility. You can satisfy it by contributing to bona fide benefit plans like health insurance or retirement accounts, by paying the fringe amount to the worker as additional cash wages, or through some combination. Whichever route you pick, the certified payroll must show the math clearly enough for an auditor to confirm total compensation meets or exceeds the wage determination rate.⁴

Overtime is required at time-and-a-half for any hours beyond 40 in a workweek under the Contract Work Hours and Safety Standards Act.⁶

Classification Is Where Contractors Get Hurt

Every worker must be assigned a classification matching a trade listed in the contract’s wage determination. When a worker performs duties spanning two classifications, they are paid the higher rate for the hours spent on the higher-paid work.

Misclassification, whether accidental or deliberate, is the compliance failure that costs contractors the most money. If the DOL believes workers were misclassified, it can assume every worker in that trade spent all their time on the higher-paying tasks unless the contractor’s own records prove otherwise. The burden of proof sits on you.

When a project needs a type of work that is not in the original wage determination, you cannot invent a classification and pick a rate. You submit a Standard Form 1444, “Request for Authorization of Additional Classification and Rate,” to the contracting officer.⁷ The request describes the classification title, the duties, and the proposed wage and fringe rate. If the parties agree, the contracting officer recommends approval to the DOL’s Wage and Hour Division. If they cannot agree, the Wage and Hour Division decides. Paying workers under an unapproved classification creates back-wage exposure if the DOL later sets a higher rate.

Apprentice Rules

Apprentices can be paid below the full journeyworker rate on Davis-Bacon projects, but only under strict conditions. The apprentice must be individually registered in a program approved by the DOL’s Office of Apprenticeship or a recognized State Apprenticeship Agency.⁸ A worker in their first 90 days of probationary employment may also qualify if the appropriate agency has certified their eligibility. Without proper registration, anyone labeled “apprentice” must be paid the full journeyworker rate for their classification.

There is also a ratio cap between apprentices and journeyworkers on site. The allowable ratio is the one from the apprentice’s registered program or the ratio applicable to the project’s locality, whichever is lower, and compliance is measured daily rather than weekly.⁸ Exceed the ratio on a given day and every apprentice beyond the allowed number gets the full prevailing wage for that day’s work. Contractors working outside the area where their apprenticeship program is registered must follow the local program’s ratios and rates.

Posting and Recordkeeping

Contractors must post the applicable wage determination and the Davis-Bacon poster (WH-1321) in a prominent, accessible spot on the job site where workers can see them.¹ The posting exists so workers can verify their own paychecks against the published rates.

All payroll records, both the certified submissions and the underlying regular payroll records, must be preserved for at least three years after all work on the prime contract is completed.⁹ The clock starts from completion of the entire prime contract, not from when your subcontract wraps up. On multi-year projects that means holding records for a long stretch. Electronic storage and submission are acceptable.

What Non-Compliance Costs

The enforcement structure has real teeth, and consequences scale with the severity and intent of the violation.

Back wages. The contracting agency can withhold funds from the contractor’s payments to cover any prevailing wage shortfalls owed to workers. The prime contractor is liable for wage deficiencies of its subcontractors, not just its own employees.
Overtime liquidated damages. Violating the 40-hour overtime rule under the Contract Work Hours and Safety Standards Act triggers liquidated damages of $33 per affected worker for each calendar day the violation occurred.¹⁰
Contract termination. The government can terminate for cause when a contractor fails to meet Davis-Bacon requirements, leaving the contractor liable for any additional costs the government incurs to complete the work.¹
Debarment. For willful or repeated violations, the contractor, its responsible officers, and any affiliated companies face debarment from all federal and federally assisted contracts for three years. Debarred names are published on SAM.gov.¹¹
Criminal prosecution. Falsifying certified payroll reports can result in up to five years of imprisonment under federal false-statement laws.⁵

What Changed in the 2023 Rule Update

The DOL finalized a major update to its Davis-Bacon regulations that took effect in late 2023 and into 2024.¹² Several changes affect certified payroll directly.

The definition of “site of the work” was expanded to more clearly cover secondary sites where significant portions of a building or structure are constructed, even when that work happens off the primary job site. Contractors who fabricate major components at a separate facility may now need to pay prevailing wages for that work and report it on certified payroll.

The updated rules also formally recognize electronic signatures and electronic submission of certified payroll reports. Recordkeeping requirements now include maintaining worker phone numbers and email addresses alongside traditional payroll data, and the rule distinguishes more explicitly between the regular payroll records contractors keep internally and the certified payroll documents they submit each week.
