The WH-347 changed. The old form dies September 30, 2026.
The WH-347 is the weekly certified payroll report every contractor and subcontractor files on Davis-Bacon covered work. In January 2025 the Department of Labor released a revised version, and the prior form is accepted only through September 30, 2026. After that, submitting on the old form is a compliance problem on every federal project you touch.
What changed on the revised form
- A dedicated Wage Determination Number field: each report now identifies the wage determination that governs the project.
- Worker classification split into explicit fields, with new columns for Journeyworker, Registered Apprentice, and Worker Entry Number.
- Expanded fringe benefit reporting: Total Fringe Benefit Credit and Payment in Lieu of Fringe Benefits are now separate entries, so cash-in-lieu is visible instead of buried in the rate.
- A more structured Statement of Compliance, with apprenticeship program details.
- The Number of Withholding Exemptions column is gone.
The current form and instructions live on DOL’s WH-347 page. Verify requirements there; this page is a summary, not legal advice.
The new field is a wage determination number. Do you know yours?
The revised form asks, on every weekly report, which wage determination your rates come from. That is exactly the question WagePin answers: look up your county and construction type from the home page and you get the governing determination, its current revision, and the full classification table. Pin your bid date and you get the revision that legally applied when you bid, per the FAR 22.404-6 ten-day rule, which is the one your certified payroll should be consistent with.
Rates on the form have to match rates in force
Most certified payroll findings are not fraud, they are stale rates: a determination was modified mid-project and nobody noticed. WagePin tracks every substantive revision and can email you a classification-level diff the night a change publishes. Watch your determination or your county from its page, and the rate that changed is in your inbox before it is in an auditor’s finding.
Common questions
Is the WH-347 form itself mandatory?
No. The form is optional, but the weekly certified payroll submission and everything on it is required by 29 CFR 5.5 on Davis-Bacon covered contracts. WH-347 is the format agencies expect, and using it means nothing required is missing.
When is the deadline to switch to the revised WH-347?
The prior version of the form is accepted only through September 30, 2026. The revised form is accepted now, so there is no reason to wait for the deadline.
How often is certified payroll due?
Weekly, within seven days after the regular pay date, for every week the contractor or subcontractor performs work on the covered project.
Where do I find the wage determination number the revised form asks for?
It is in your contract or bid documents, and you can confirm it by looking up the project county and construction type on WagePin, which also shows which revision was in force on your bid date.
Do wage determination changes after award affect my certified payroll?
Usually not on a fixed-price contract, where the determination locks at bid opening or award. But option exercises, some annual updates, and new task orders can pull in a newer revision, so watching your determination is cheaper than finding out in an audit.
Before September 30, 2026
- Switch to the revised WH-347 now rather than at the deadline; agencies already accept it.
- Confirm the wage determination number and revision for each active project, and pin them.
- Set a watch on each project’s determination so mid-project modifications reach you the week they publish.
