What is certified payroll?

Certified payroll is the weekly payroll report a contractor or subcontractor on a Davis-Bacon covered contract submits, with a signed Statement of Compliance, to show each laborer and mechanic was paid at least the prevailing wage and fringe benefits for the work they did. It is due for every week covered work is performed, within 7 days after the regular payday, often on the Department of Labor's optional Form WH-347.

When is certified payroll required?

On federal construction contracts over $2,000 and on many federally assisted projects. The Davis-Bacon Act applies to every contract in excess of $2,000 for construction, alteration or repair, including painting and decorating, of public buildings and public works, and requires the contract to list the minimum wages for each class of worker (40 U.S.C. 3142(a)). Those lists are the wage determination. The weekly payroll requirement in 29 CFR 5.5(a)(3)(ii) covers both Davis-Bacon and Related Acts work, the federal funding statutes that carry the same prevailing wage terms.

Who is covered
Laborers and mechanics employed on the site of the work, paid at least once a week, regardless of any contractual relationship claimed between them and the contractor (40 U.S.C. 3142(c)).
Who is not
Private jobs with no federal contract or federal assistance. State and local prevailing wage programs may still apply; in California, for example, Labor Code 1776 sets payroll record rules for public works.

Who submits certified payroll, to whom, and when?

Every contractor and subcontractor with covered workers, every week covered work happens. Payrolls go to the federal agency if it is a party to the contract; otherwise to the applicant, sponsor, owner or other entity that keeps the records and passes them to the funding agency. The prime contractor is responsible for submitting all subcontractors' certified payrolls (29 CFR 5.5(a)(3)(ii)(A)).

One payroll week, Saturday to Friday, paid the following Wednesday

  1. Saturday to FridayCovered work performed. Hours recorded by worker, day and classification.
  2. Following WednesdayRegular payday. Workers must be paid at least once a week.
  3. Within 7 days after paydayCertified payroll delivered, so by the next Wednesday (29 CFR 3.4(a)).
  4. 3 years after the prime contract's work is completeEarliest date the underlying payroll records may be discarded (29 CFR 5.5(a)(3)(i)).

What goes on Form WH-347?

One row per worker per classification, with daily hours, rates, fringe benefits and pay. The form itself is optional: payrolls may be submitted on Form WH-347 or in any other format, as long as they carry the same information and a Statement of Compliance with identical wording. Never include a full Social Security number or home address on the weekly transmittal; an individually identifying number such as the last four digits is enough (29 CFR 5.5(a)(3)(ii)(B)).

Form WH-347, page 1, and where preparers trip up
ColumnWhat it holdsCommon slip
1A to 1EEntry number, name and an individual identifying number.Full SSN on the form. A worker with two classifications needs two rows with the same entry number.
2J for journeyworker or RA for registered apprentice, with the apprentice's level.Marking someone RA who is not individually registered in a program.
3Classification of the work actually performed, from the wage determination.Using the worker's job title instead of the work done that day.
4Straight time and overtime hours for each day.Counting overtime only on this project. Overtime is hours over 40 in the week, including other jobs.
5Total hours worked on the project that week.Not matching the daily entries in column 4.
6AHourly rate actually paid, straight time and overtime.Including cash paid in lieu of fringe here; it belongs in 6C.
6BTotal fringe benefit credit: hours times the hourly credit from page 2.Crediting a plan contribution that was never annualized.
6CCash paid in lieu of fringe benefits that week.Leaving it blank when fringe was paid in cash.
7A and 7BGross earned on this project, and gross for all work that week.Leaving 7B at the project figure when the worker also worked other jobs that week.
8 and 9Deductions for all work, and net pay.Prorating deductions, or taking deductions outside the 29 CFR 3.5 list without DOL approval.

What does the Statement of Compliance certify?

That the payroll is right and every worker was paid in full. Under 29 CFR 5.5(a)(3)(ii)(C) the signer certifies that:

  • The payroll information and the supporting records are correct and complete.
  • Each worker was paid the full weekly wages earned, without rebate, directly or indirectly.
  • No deductions were made beyond those permitted under 29 CFR part 3.
  • Each worker received at least the applicable wage rates and fringe benefits, or cash equivalents, for the classification of work actually performed.

How do fringe benefits work on certified payroll?

The wage determination sets a basic hourly rate and an hourly fringe amount, and you can meet the fringe part with contributions to bona fide plans, with cash in lieu, or with a mix of both, according to the WH-347 instructions. Plan contributions count as wages paid (29 CFR 5.5(a)(1)(i)). Three rules decide whether the numbers hold up.

  • Annualize plan contributions. The hourly credit for a plan contribution is the total cost divided by all hours worked, on private and covered work, over the period the cost is attributed to (29 CFR 5.25(c)(1)). A defined contribution pension plan with immediate participation and vesting within the first 500 hours is excepted.
  • Overtime is figured on the basic rate. The contractor's fringe benefit contributions or costs may be excluded from the rate overtime is computed on; DOL's own example computes overtime on a $3.00 basic rate even though the worker was paid $3.50 in cash including fringe (29 CFR 5.32).
  • Fringe is owed on every hour worked. Column 6B is hours worked times the hourly credit, so overtime hours carry the full fringe amount at straight time; only the overtime premium is left off it.

Worked example: one electrician's week on a covered job

Made-up wage determination: electrician, basic rate $52.00, fringe $27.00 an hour. The contractor puts $20.00 an hour into health and pension plans (already annualized) and pays the other $7.00 in cash. The electrician works 44 hours on the covered project.

What the week must add up to

Straight time (6A)
40 hours x $52.00 = $2,080.00
Overtime (6A)
4 hours x $78.00 (1.5 x $52.00 basic rate) = $312.00
Fringe credit to plans (6B)
44 hours x $20.00 = $880.00
Cash in lieu of fringe (6C)
44 hours x $7.00 = $308.00
Required minimum
44 x ($52.00 + $27.00) + 4 x 0.5 x $52.00 = $3,476.00 + $104.00 = $3,580.00
Total wages and fringe
$2,080.00 + $312.00 + $880.00 + $308.00 = $3,580.00, which meets the minimum

Two classic errors: paying overtime on the $79.00 package ($118.50 an hour) overpays $54.00 that week; paying fringe on 40 hours instead of 44 underpays $108.00.

Annualizing a health plan contribution

Contractor's annual cost for this worker
$10,400.00
All hours worked in the year, private and covered
2,080
Hours on covered projects
1,040
Wrong: credit spread over covered hours only
$10,400.00 / 1,040 = $10.00 an hour
Allowable hourly credit
$10,400.00 / 2,080 = $5.00 an hour

Claiming $10.00 would leave the worker $5.00 short for every covered hour, 1,040 x $5.00 = $5,200.00 over the year.

What are the most common certified payroll mistakes?

Most errors start before the form: hours written up late, classifications guessed, and fringe credits never checked. Before signing each week, run through this list.

  • Each worker is classified by the work actually performed, with a separate row for each classification.
  • Daily hours come from a record made at the time, not filled in at the end of the week.
  • Overtime counts every hour that week, including other jobs and the shop.
  • Apprentices are individually registered and within the allowed ratio; otherwise they get the full rate for the work performed (29 CFR 5.5(a)(4)(i)).
  • Plan contributions are annualized over all hours, and cash in lieu is in column 6C.
  • Fringe is paid on overtime hours too, and overtime premiums use the basic rate.
  • Deductions are on the 29 CFR 3.5 list or approved by DOL.
  • No full SSNs or home addresses on the weekly transmittal.
  • The Statement of Compliance has an original or valid electronic signature, not a scan.
  • Subcontractor payrolls are collected and submitted by the prime every week.

How ZeroBadge handles this

ZeroBadge aids certified payroll reporting by supplying verified hours by worker, day and jobsite. It does not produce or file certified payroll on its own; final certified payroll reports require review by a qualified person.

Hours come from a company badge each worker wears, split by jobsite, so time on the covered project and time on every other job that week sit in one record. Classifications, rates and fringe stay with your payroll and compliance people. See certified payroll time tracking.

Frequently asked questions

Is certified payroll required on private construction jobs?
Not under Davis-Bacon. It applies to covered federal and federally assisted contracts. A state or local public works program may have its own prevailing wage and payroll rules, so check the contract and the state.
Who is responsible for a subcontractor's certified payroll?
The subcontractor prepares and signs its own, and the prime contractor is responsible for submitting all subcontractors' certified payrolls under 29 CFR 5.5(a)(3)(ii)(A). In practice the prime collects and checks them each week.
Is overtime on certified payroll paid on the fringe rate too?
No. Overtime is computed on the basic hourly rate, and the contractor's fringe benefit costs may be excluded (29 CFR 5.32). The full fringe amount is still owed for each overtime hour, at straight time.
Can certified payroll be signed electronically?
Yes. The DOL's WH-347 instructions accept a legally valid electronic signature that includes a way to verify the signer's identity. A photocopy or scanned signature does not satisfy the requirement.
What happens if certified payroll is wrong?
A false certification may lead to civil or criminal prosecution under 18 U.S.C. 1001 and 31 U.S.C. 3729, and underpaid wages and fringe still have to be paid. Fix an error as soon as you find it and tell the agency or prime contractor what changed. This is general information, not legal advice.
