How to file certified payroll in Arizona (Davis-Bacon WH-347)

No state prevailing wage — federal funding is the trigger

Unlike California, New York, or Washington, Arizona does not impose its own prevailing-wage requirements on public works, and it bars its political subdivisions from doing so. That means a purely state- or locally funded Arizona project generally has no certified-payroll obligation. The obligation appears when federal dollars flow into the contract under the Davis-Bacon Act (and Related Acts), at which point you owe a weekly WH-347 to the contracting agency.

The WH-347 is the form

On a Davis-Bacon job you report each worker’s name, last four of the SSN, work classification, daily and weekly hours, rate, gross, deductions, and net — plus the Statement of Compliance. PayrollPenguin maps your classifications to the wage determination, handles fringe (paid in cash or to approved plans), and reshapes your weekly hours into the form’s cells. It reformats your numbers; it never invents a wage.

ADOT and other federal-aid road work

Federally funded highway projects through the Arizona Department of Transportation (ADOT) can require certified payroll submitted through a portal such as LCPtracker or AASHTOWare Project Payroll, depending on the project. The underlying form is still the Davis-Bacon WH-347. Check your contract’s labor-compliance terms for the exact submission method per job — it varies by award.

How to file Arizona certified payroll

1. Import your payroll run. Upload your ADP, Gusto, QuickBooks, Paychex, or CSV payroll for the pay period.
2. Pick the federally funded project. Select the Davis-Bacon project and attach its wage determination so classifications map to the right rates.
3. Resolve anomalies. PayrollPenguin flags missing fringe, classification gaps, rates below the wage determination, and zero-hour weeks before you can certify.
4. Certify and export the WH-347. Sign the Statement of Compliance, then download the file-ready WH-347 to submit to the contracting agency (or upload to LCPtracker / AASHTOWare if your ADOT job requires it).

Frequently asked questions

Does Arizona have a state prevailing-wage law?

No. Arizona has no state prevailing-wage law, and the state constitution and statute bar local prevailing-wage mandates. Certified payroll is required only on federally funded work under the Davis-Bacon Act, filed on the federal WH-347. There is no separate Arizona state form or portal.

Which Arizona projects need certified payroll?

Projects that carry federal funding subject to Davis-Bacon (and Related Acts). A purely state- or locally funded Arizona job generally has no certified-payroll obligation. Federal-aid ADOT highway projects may also require submission through LCPtracker or AASHTOWare Project Payroll — check the labor-compliance terms in your contract for each job.

Is PayrollPenguin a compliance guarantee?

No. PayrollPenguin is a reporting and formatting tool — it formats your payroll to the WH-347 specification and flags anomalies for your review. You certify and the contracting agency / DOL reviews.
