How often is Form WH-347 due, and when?

It is a weekly report. Contractors generally submit the certified payroll within seven days after the end of each regular pay period for every week covered work is performed. Weeks with no covered work still require a "no work" report. Confirm the exact timing in your contract clauses.

Where do I submit the completed form — does AttachKit file it for me?

No. AttachKit only fills the PDF on your device; it never submits anything. You file the signed payroll with the federal agency that is a party to the contract, or with the prime contractor, sponsor, or owner who forwards it to that agency, as your contract directs.

What is the difference between WH-347 and WH-348?

WH-348 is the standalone Statement of Compliance — the signed certification that appears as page 2 of WH-347. WH-347 combines the weekly payroll grid and that certification in one form. Using WH-347 itself is optional, but submitting the weekly certified payroll data is required under the Davis-Bacon regulations.

What are the most common WH-347 mistakes?

Frequent errors include misclassifying workers against the applicable wage determination, mixing up the fringe-benefit columns (paid into a plan vs. paid in cash in lieu of benefits), leaving apprentice or deduction details undocumented, and forgetting to sign the Statement of Compliance. Review these before you print — AttachKit fills fields but does not check compliance.

Fill Form WH-347 certified payroll online — free

Form WH-347 is the U.S. Department of Labor's weekly certified payroll report for laborers and mechanics on federal and federally-assisted construction contracts covered by the Davis-Bacon and Related Acts. Contractors and subcontractors use it to document each worker's classification, hours, pay rate, gross wages, deductions, and fringe benefits, and to sign the Statement of Compliance on page 2 certifying the payroll is correct and that prevailing wages were paid. It is issued by the DOL Wage and Hour Division (OMB No. 1235-0008) and is submitted to the federal contracting agency — or to the prime contractor, sponsor, or owner who forwards it to that agency. Bring the official blank DOL PDF (we link it below); AttachKit auto-fills the repeating header fields — contractor name and address, project name and location, and the payroll number — from your saved profile, on your device. AttachKit does not submit the form to the DOL or any agency, and does not give legal or wage-compliance advice; you print, sign, and file it yourself.

Your PDF never leaves your browser — open DevTools → Network and watch: the file is never uploaded.

Who needs it: Prime contractors and subcontractors performing construction work on federal or federally-funded projects covered by the Davis-Bacon Act must file a certified payroll every week the project runs. Because it repeats weekly — including a "no work" report for weeks with no covered labor — payroll and compliance staff fill it constantly for the life of a contract.
