If you run a crew in Pennsylvania, the PA workers' comp requirements turn on a handful of things that trip contractors up constantly: the one-employee mandate, the Act 72 misclassification test that decides who counts as an employee, which owners and officers you can actually exclude, what the state can do to you if you go bare, the Section 302 statutory-employer rule that makes a GC pay for an uninsured sub, how the PCRB prices construction risk, and what a subcontractor's certificate has to say before anyone sets foot on the job.

Pennsylvania requires every employer with one or more employees to carry workers' compensation from that employee's first day — there is no payroll floor, so in construction a single helper triggers the mandate. The Construction Workplace Misclassification Act (Act 72) presumes a construction worker is an employee unless the hiring contractor can prove a written contract, freedom from control, and an independently established business — which is why handing someone a 1099 does not, by itself, get you out of the requirement.
The Pennsylvania Workers' Compensation Act (Act 338 of 1915) is blunt about it: every employer with one or more employees has to carry workers' compensation — or qualify as an approved self-insurer — starting on the employee's first day. No waiting period. No minimum-payroll floor. It applies whether the worker is full-time, part-time, seasonal, or your cousin helping out for the summer. For a contractor, that one line decides everything: put a single helper on a roof and the mandate is already live.
Pennsylvania runs a competitive private market — not a monopolistic state fund — so more than 300 licensed carriers write WC in the Commonwealth and you can buy from any of them through a licensed broker. Sitting behind that market is the State Workers' Insurance Fund (SWIF), the state-run insurer that by statute has to cover virtually every PA business that applies. That makes SWIF the backstop for the trades private carriers tend to run from — roofing, demolition, excavation. Self-insurance is on the menu too, but realistically only for large, well-established employers who can post security with PA L&I.
So the three ways to be compliant are: a private carrier placed through a licensed broker, SWIF, or approved individual or group self-insurance. Acolite places Pennsylvania workers' comp for contractors and quotes the private market alongside SWIF. We're a licensed broker, not an insurer, and every placement is subject to carrier underwriting.
The Construction Workplace Misclassification Act (Act 72 of 2010, effective February 10, 2011) writes a statutory definition of "independent contractor" for workers' comp and unemployment purposes — and it does so for the construction industry specifically. Here's the part that matters: it presumes a construction worker is an employee, and the only way to rebut that is for the hiring party to prove every element of the test below. The burden sits on the contractor, not the worker. That's why a 1099 form, on its own, proves nothing.
To treat a construction worker as an independent contractor under Act 72, you have to satisfy all of the following — miss one and the worker is an employee:
Per current PA Department of Labor & Industry guidance, Act 72 misclassification penalties run up to $1,000 for a first violation and up to $2,500 for each one after that, assessed per misclassified worker — and L&I can drop a stop-work order that freezes the project until you fix it. Intentional violations are graded as a misdemeanor, negligent ones as a summary offense. Because these criteria and dollar figures get updated, treat the amounts as a guide and confirm them against the Act 72 statute and PA L&I before you rely on them.
Pennsylvania's exemptions are narrow, and several are opt-out elections — meaning coverage is the default and you have to file to get out. The construction reality is simple: exemptions cover owners, not the crew. You cannot exempt your way out of covering employees.
Executive officers with an ownership stake can elect to exclude themselves, but it takes two forms filed together — LIBC-509 (Application for Executive Officer Exception) and LIBC-513 (Executive Officer's Declaration) — submitted to the WC carrier, or to the Bureau of Workers' Compensation if there are no other employees. The declaration asks the officer to certify ownership in a Subchapter S corporation, at least 5% ownership in a Subchapter C corporation, or unpaid service in a nonprofit. The trade-off: an excluded officer collects no WC benefits if they get hurt.
LLC members and partners with ownership can usually be excluded under similar elections, depending on the entity and the carrier's endorsement — though a member who's swinging a hammer alongside the crew often wants coverage anyway, because jobsite injuries don't care about the org chart. A sole proprietor with no employees isn't required to cover themselves and generally isn't on a standard policy — but the day they hire one employee, or a worker who flunks the Act 72 test, the mandate attaches. There's also a narrow religious exemption via LIBC-14A. None of this overrides Act 72: a "subcontractor" who fails the independent-contractor test is your employee, no matter what exclusion forms are sitting in a drawer.
Going without required WC in Pennsylvania isn't a paperwork slip — it's a crime, and it's charged per day. Every uninsured day is its own separate offense.
| Violation | Grading | Maximum (per day uninsured) |
|---|---|---|
| Failure to insure | Misdemeanor | Up to $2,500 fine + up to 1 year imprisonment |
| Intentional failure to insure | Felony (third degree) | Up to $15,000 fine + up to 7 years imprisonment |
On top of the criminal side, ignoring a Bureau of Workers' Compensation inquiry can draw civil penalties (commonly cited at up to $200 per day), and corporate officers can be held personally liable — the corporate veil won't save them. But the real exposure is losing the exclusive-remedy shield. An employer that skips required WC can be sued directly in tort by an injured worker with no statutory cap, and the Uninsured Employers Guaranty Fund can pay that worker's benefits and then come after the business and its owners to get it back. The premium you "saved" rarely survives one serious claim. Verify current amounts against PA L&I, since they're periodically updated.
Section 302 of the WC Act is the rule that should make every GC care about a sub's paperwork. A contractor who subcontracts part of its work — and that contractor's insurer — is on the hook to pay workers' compensation to the subcontractor's employees unless the subcontractor secured its own coverage. Translated: if your sub is uninsured and the sub's worker gets hurt on your job, you, the GC, pay the WC benefits as the statutory employer. Your carrier handles the claim, your loss experience eats it, and at audit the uninsured sub's payroll gets bolted onto your premium.
Pennsylvania courts decide statutory-employer status with a five-element test (the McDonald test):
It does cut both ways. A GC that's a statutory employer is secondarily liable for an uninsured sub's WC, but it usually also picks up tort immunity — the exclusive-remedy bar — against suits from that sub's injured workers, plus a right to seek indemnification from the sub that should have carried the coverage. Still, the only practical defense against absorbing a sub's claim and back-premium is to require, collect, and actually verify a current certificate of insurance from every subcontractor. Acolite helps verify subcontractor certificates before work starts.
Pennsylvania isn't an NCCI state. Classification and loss costs come from the Pennsylvania Compensation Rating Bureau (PCRB), which administers roughly 330 classifications for its member carriers. Construction gets carved into granular codes by trade and hazard, and the high-hazard trades carry the steepest rates per $100 of payroll — roofing (steep-roof and torch-down included), structural steel and iron erection, excavation and trenching, and demolition sit at the top, with carpentry, masonry, concrete, and inside electrical and plumbing elevated but lower. Slotting payroll into a cheaper code to shave premium is a form of fraud, and the auditor catches it with back premium attached.
The math is roughly payroll per $100 × rate × experience modifier × credits and debits, estimated at bind from projected payroll and trued up at a year-end audit against what you actually paid and which subs you actually used. Once you clear a premium-size threshold, the PCRB issues an experience modification factor (EMR) built from your actual versus expected losses — under 1.00 credits your premium, over 1.00 debits it. In construction the EMR doubles as a bid qualifier, because plenty of owners and GCs won't let a sub prequalify above a stated mod.
Pennsylvania also runs the Pennsylvania Construction Classification Premium Adjustment Program (PCCPAP) — a construction-only premium credit for employers who pay above the statewide average wage for their class code. It isn't automatic; you apply to the PCRB and document the qualifying wages. For union and higher-wage open-shop contractors it can be a real, legitimate reduction. SWIF can be quoted alongside the voluntary market and is sometimes competitive for smaller operations, but it isn't automatically the cheaper option, and its endorsement choices differ from private carriers (more on that below).
Before you mobilize, Pennsylvania owners and GCs typically want proof of active PA-state-rated WC coverage by certificate — naming the right insured entity, with policy dates that span the full scope of work and a re-check at expiration. A few contract terms come up again and again:
Acolite places Pennsylvania workers' comp for contractors and helps verify subcontractor certificates — EL limits and waiver-of-subrogation wording included — before work starts.
These are the gaps that competitors gloss over and that cause denied claims or rejected certificates.
In construction, Act 72 starts from the assumption that your worker is an employee and makes you prove otherwise — a written contract, freedom from control, and an independently established business, right down to the $50,000 liability-insurance criterion. A 1099 proves none of that. A misclassified worker becomes your employee, and the bill arrives as back WC premium, unemployment assessments, and Act 72 penalties.
Under Section 302, if a sub is uninsured and its worker gets hurt on your job, you're the statutory employer and your WC pays the claim — and that sub's payroll lands on your premium at audit. Collect and verify a current PA WC certificate from every sub before they mobilize, not after.
Excluding an executive officer isn't automatic. It takes LIBC-509 and LIBC-513 filed together (with the carrier, or the Bureau if there are no other employees), and the officer has to clear an ownership threshold. An excluded officer gets no WC benefits if injured — and the exclusion never reaches the working crew.
If your contract demands a waiver of subrogation in favor of the GC or owner and SWIF is your only market, you may not be able to comply — SWIF doesn't issue waiver-of-subrogation endorsements. Check the waiver requirement against your available market before you sign.
Upstream contracts often set the Part B / Employers' Liability limit (frequently $500K/$500K/$500K or $1M). EL answers statutory-employer and action-over exposures, so a policy that satisfies the statutory WC requirement can still come up short of the contract's EL limit.
A policy rated in another state that doesn't list Pennsylvania can leave your PA payroll uncovered and fail a GC's certificate review. Confirm the policy is PA-state-rated for the work you're doing in the Commonwealth.

| Factor | Impact | Detail |
|---|---|---|
| High-hazard construction class codes | Major | PCRB rates trades by hazard. Roofing, structural steel and iron erection, excavation and trenching, and demolition sit at the highest rates per $100 of payroll; carpentry, masonry, concrete, and inside electrical and plumbing run lower but still elevated. |
| Experience modifier (EMR) | Major | Clear a premium-size threshold and the PCRB issues an experience mod from actual versus expected losses. Below 1.00 credits premium, above 1.00 debits it — and many GCs require subs to prequalify below a stated mod, so claims history drives both price and eligibility. |
| Payroll and subcontractor usage | Major | Premium is payroll-based and trued up at a year-end audit. Uninsured subcontractors get added to the GC's payroll on audit, so skipping sub certificates raises the final premium after the fact. |
| PCCPAP wage credit | Moderate | The Pennsylvania Construction Classification Premium Adjustment Program credits construction employers who pay above-average wages for their class code. It isn't automatic — you apply to the PCRB and document the qualifying wages. |
| SWIF vs voluntary market | Moderate | SWIF is the guaranteed market and can be competitive for smaller operations, but it isn't automatically the cheaper option and doesn't issue every endorsement — waiver of subrogation in particular. Quoting the voluntary market alongside SWIF typically matters for both price and contract compliance. |
Yes — at one employee. There's no payroll minimum and no waiting period; coverage is required from the worker's first day, including part-time, seasonal, and family employees.
No — a true sole proprietor with zero employees doesn't have to cover themselves and generally isn't on a standard policy. But the day they hire one employee, or a worker who fails the Act 72 test, coverage becomes mandatory. And since most GCs contractually require a certificate even from one-person subs, plenty of sole proprietors buy a policy anyway just to win the work.
Act 72 (effective February 10, 2011) defines who can be treated as an independent contractor in the construction industry for WC and unemployment purposes. It presumes construction workers are employees unless the hiring party proves a written contract, freedom from control, and an independently established business — six specific sub-criteria, including carrying at least $50,000 in liability insurance. Fail any element and the worker is your employee.
Each uninsured day is its own offense: a misdemeanor carrying up to $2,500 and up to one year imprisonment per day, while an intentional failure is a felony of the third degree carrying up to $15,000 and up to seven years per day. Officers can be personally liable, and the employer loses exclusive-remedy protection, opening the door to direct tort suits and the Uninsured Employers Guaranty Fund. Verify current amounts with PA L&I.
No. In construction, Act 72 presumes employee status and puts the burden on you to prove every element of the independent-contractor test. A 1099 alone proves nothing — misclassification triggers Act 72 penalties, back WC premium, and unemployment assessments.
Under Section 302 of the WC Act, a general contractor is the statutory employer of an uninsured subcontractor's employees — so the GC's WC has to pay benefits if that sub's worker is injured on the job. In exchange, it generally gives the GC tort immunity from those workers, plus a right to recover from the sub.
You do — the GC and the GC's WC carrier, as statutory employer. At audit, the uninsured sub's payroll also gets added to the GC's premium. That's exactly why collecting and verifying valid subcontractor certificates is non-negotiable.
Yes — executive officers with ownership can elect exclusion by filing LIBC-509 and LIBC-513 together, with the carrier or with the Bureau if there are no other employees. An excluded officer collects no WC benefits if injured, and the exclusion covers owners, never the working crew.
From the Pennsylvania Compensation Rating Bureau (PCRB), which administers roughly 330 classifications and loss costs for member carriers. High-hazard construction codes — roofing, steel erection, excavation, demolition — carry the highest rates per $100 of payroll.
The Pennsylvania Construction Classification Premium Adjustment Program credits construction employers who pay above-average wages for their class code. It isn't automatic — you apply to the PCRB and document the qualifying payroll.
Yes, on the private market — Pennsylvania lets an employer waive its subrogation rights (per Bowman v. Sunoco), and a waiver-of-subrogation endorsement is generally available and commonly required by GCs. Just know that SWIF doesn't issue them, which can be a problem for contractors whose only market is SWIF.
Probably, yes — in practice. If any "sub" fails the Act 72 test, they're your employee; if a sub is uninsured, you're their statutory employer. Most GCs end up needing their own policy plus disciplined certificate collection. An "all subs, no policy" posture is high-risk in Pennsylvania construction.
