- $25,000 threshold: prevailing wage applies to public works projects costing $25,000 or more.
- No splitting: a public body can't carve one project into sub-$25,000 contracts to dodge it.
- Weekly certified payroll: submitted to the public body that awarded the contract — there's no single state portal.
- Keep records 2 years: available to L&I and the awarding body on request.
- Penalties: back wages, civil fines, withheld payments, up to 3-year debarment, and criminal misdemeanor exposure for false filings.
The thing that makes Pennsylvania different
California has eCPR. New Jersey has the Wage Hub. New York has its portal. Pennsylvania has none of that. You submit your weekly certified payroll directly to the public body that awarded the contract — the school district, the township, the authority. That sounds simpler, but it's actually a trap for small subs: every agency wants it a little differently, there's no single confirmation that you filed, and "I gave it to the project office" is a weak defense when L&I comes asking two years later. The lack of a portal means the burden of proof sits entirely on your records.
When it applies: the $25,000 line
The Pennsylvania Prevailing Wage Act covers public works projects with a total cost of $25,000 or more. Below that, prevailing wage generally doesn't attach. Important: a public body can't split a single project into several sub-$25,000 contracts to slip under the line — Labor & Industry treats fragmented contracts for the same unified scope as one contract. So don't assume a string of small change orders or phases keeps you exempt; look at the whole project.
How you file: weekly, to the awarding body
Contractors and subcontractors performing public work must complete and submit weekly certified payrolls to the public body that awarded the contract. Each record has to show, for every worker on the public works project:
- Name and craft or classification (based on the work actually performed).
- Hours worked each day and the weekly total.
- Hourly wage rate, including benefits — base plus fringe meeting the determination.
- Deductions taken from each worker.
And you must keep these records for at least two years, with access provided to Labor & Industry and the awarding public body at reasonable hours.
Penalties can include recovery of back wages, civil fines, and withholding of contract payments — plus debarment up to 3 years from public works.
Debarred contractors land on a public list, so the reputational hit outlasts the bar itself. And falsifying a certified payroll can be prosecuted as a criminal misdemeanor — this is a record you're certifying as true, not a formality.
The classification and fringe trap
As in every prevailing wage state, most Pennsylvania trouble starts with the rate, not the paperwork. You classify each worker by the work actually performed, then pay the prevailing base wage plus the listed fringe for that classification and county. Underpay — or count an hour at the wrong craft — and your own weekly certified payroll becomes the evidence. Because there's no portal sanity-checking your entries, nothing catches the mistake until an audit does.
How to stay clean in Pennsylvania
- Check the $25,000 line on the whole project, not the piece you're doing.
- Submit weekly to the awarding public body — and keep a dated copy of every submission.
- Hold records two years so you can answer L&I or the public body fast.
- Classify by the work performed and pay the correct prevailing base + fringe.
- Treat the certification seriously — a false payroll is a criminal matter, not a clerical one.
No state portal? Keep your own clean record
PrevailComply does the classification and fringe math, generates your federal WH-347 and a Pennsylvania-ready certified payroll, and keeps a dated, exportable trail for every awarding body — so when L&I asks two years later, you have proof. Tell us you're in PA and we'll prioritize it.
The bottom line
Pennsylvania's lack of a portal isn't a break — it shifts the whole burden of proof onto your own records. Submit weekly to the awarding body, keep dated copies for two years, and pay the right rate. Start your federal report with the free WH-347 generator, walk the federal form with the WH-347 step-by-step guide, and see what penalties add up to with the fine calculator. New to public works?

This guide is general information for small subcontractors, not legal advice, and reflects Pennsylvania Department of Labor & Industry guidance on the Prevailing Wage Act as of June 2026. Thresholds, submission practices, and penalties can change and individual awarding bodies set their own submission details — confirm against current PA L&I guidance and your project's documents.
