Certified Payroll Reporting: Davis-Bacon and Related Acts

Certified payroll reporting is a federal compliance requirement applicable to contractors and subcontractors performing work on federally funded or federally assisted construction projects. Rooted in the Davis-Bacon Act of 1931 and extended by a family of Related Acts covering specific federal program areas, the requirement mandates that workers receive no less than the prevailing wage for their trade in the locality where work is performed. Weekly submission of Department of Labor Form WH-347 — or an equivalent document — creates an auditable record that wage and fringe benefit obligations have been met on covered contracts.

Definition and scope

The Davis-Bacon Act (40 U.S.C. §§ 3141–3148) applies to federal construction contracts valued at more than $2,000. Certified payroll, as defined under that statute and implementing regulations at 29 CFR Part 5, is a weekly payroll report accompanied by a signed statement of compliance affirming that wages paid are not less than the applicable wage determination for each labor classification.

"Related Acts" is the collective term for roughly 60 federal statutes that incorporate Davis-Bacon prevailing wage standards by reference, including the Federal-Aid Highway Act, the National Housing Act, and the Federal Transit Act. Each of these statutes extends the wage and certified payroll requirement to specific program categories — highway construction, housing projects, and transit infrastructure, respectively — funded through grants, loans, or other federal financial assistance rather than direct federal contracts.

The scope covers all mechanics and laborers working on the physical construction, alteration, or repair of the covered project. It excludes workers performing only supervisory, administrative, or clerical functions, as well as bona fide apprentices enrolled in programs registered with the Department of Labor's Office of Apprenticeship.

For additional context on how prevailing wage obligations interact with broader payroll compliance, the payroll compliance reference section addresses the regulatory framework across multiple wage statutes.

How it works

Certified payroll reporting operates through a weekly cycle tied to the project's pay schedule. Each contractor and subcontractor on a covered project must:

1. Determine applicable wage determinations — The contracting agency obtains wage determinations from the Wage and Hour Division (WHD) of the Department of Labor using the SAM.gov wage determination portal. These determinations specify the basic hourly rate and fringe benefit rate for each covered classification in the county or geographic area where the project is located.
2. Pay covered workers no less than the prevailing rate — Fringe benefits can be satisfied through bona fide plan contributions (health insurance, pension) or paid in cash on top of the basic rate. The interaction between fringe benefit deductions and gross wage calculations is covered under payroll deductions.
3. Complete Form WH-347 weekly — The form captures each worker's name, classification, hours worked each day, hourly rate, gross wages, itemized deductions, and net wages paid for the workweek.
4. Execute the Statement of Compliance — The back of Form WH-347 contains a certification, signed under penalty of law, that the information is correct and complete.
5. Submit to the contracting agency — Completed forms are submitted to the federal agency or its designated representative within 7 days of the regular payment date for the covered workweek.
6. Retain records for 3 years — Under 29 CFR § 5.5(a)(3), payroll records must be preserved for 3 years after the project's completion. Recordkeeping obligations on covered projects align with the broader standards discussed under payroll recordkeeping.

The certified payroll process also requires that contractors make payroll records available for inspection by the WHD or the contracting agency upon request.

Common scenarios

Multi-tier subcontracting — On construction projects of any scale, a general contractor may engage 10 or more subcontractors across trades. Each tier is independently responsible for its own certified payroll submissions. The prime contractor remains liable for ensuring subcontractor compliance and must collect copies of subcontractor certified payrolls for its own files.

Mixed-funding projects — A project partially funded by federal grant and partially by state or local funds is subject to Davis-Bacon on the federally funded portion. Where state prevailing wage laws (commonly called "Little Davis-Bacon" acts) also apply, the higher of the two wage determinations governs each classification. Multi-state payroll considerations become relevant when a contractor operates across state lines on federally funded work.

Classification disputes — Workers performing duties spanning two classifications — for example, an operator who also performs laborer work — must be paid the higher applicable rate for all hours worked in each classification, or the contractor must maintain accurate records demonstrating actual hours in each classification. Misclassification is a primary trigger for WHD investigations.

Employee classification overlap — The use of independent contractors on Davis-Bacon projects warrants careful review. The WHD applies an economic reality test, and workers who qualify as employees under that standard must appear on the certified payroll regardless of how the contractor has labeled the relationship. Employee classification analysis is a prerequisite before assigning any worker to a covered project.

Decision boundaries

When certified payroll is required vs. not required:

Penalties for non-compliance: The Copeland Act (18 U.S.C. § 874; 40 U.S.C. § 3145) prohibits kickbacks from wages and authorizes criminal penalties. Contractors found to have knowingly falsified a certified payroll statement face fines and potential debarment from federal contracting for up to 3 years under 29 CFR § 5.12.

Overtime on covered projects: Davis-Bacon establishes prevailing wage floors but does not independently govern overtime. Overtime obligations on federal contracts arise under the Contract Work Hours and Safety Standards Act, which applies to contracts exceeding $100,000 (40 U.S.C. § 3702) and requires overtime at 1.5 times the basic rate of pay for hours exceeding 40 in a workweek. The interaction with standard overtime rules is addressed under overtime pay rules.

For professionals managing reporting obligations across multiple active projects, the payroll deadlines and calendar reference consolidates key federal submission timelines.
