What workers compensation means for a general contractor goes far beyond the textbook definition. You need to know who pays, what triggers your liability, how WC connects to OSHA enforcement, and where the boundaries sit between WC and employer's liability. This Q&A guide answers the 15 questions GCs ask most about workers compensation in construction.

Construction workers file over 163,000 nonfatal injury claims requiring days away from work each year, according to BLS 2023 data. Every one of those claims runs through the WC system. Understanding how the system works protects your projects and your bottom line.

Who Pays for Workers Compensation?

The employer pays 100% of WC premiums. Workers never contribute to WC costs through paycheck deductions. This distinguishes WC from health insurance, where employers and employees often split the cost.

For a construction sub with $1 million in annual payroll and a composite WC rate of $8.50 per $100, the annual WC premium is $85,000. The sub absorbs this cost. If the sub has an EMR of 0.85, the adjusted premium drops to $72,250. If the EMR is 1.25, it climbs to $106,250.

GCs do not pay WC premiums for subcontractor employees. However, if a sub lacks WC coverage, the GC's own carrier may charge the GC for the sub's uninsured payroll during the annual audit.

Who Pays	What They Pay	When
Subcontractor (employer)	WC premiums for their workers	Monthly or quarterly
General contractor	WC premiums for GC employees only	Monthly or quarterly
GC (if sub uninsured)	Sub's payroll added to GC audit	At annual audit
Injured worker	Nothing	Never
Project owner	Nothing (directly)	Never

What Happens If a Sub Does Not Carry WC?

The statutory employer doctrine activates. In 38 states, the GC becomes the legal employer of the sub's workers for WC purposes. Your WC policy pays the injured worker's claim. Your EMR absorbs the loss. Your premiums increase for three years.

The dollar impact depends on the injury severity. A broken arm costs roughly $28,000 in WC benefits. A permanent back injury can exceed $150,000. A fatality may reach $500,000 or more in total benefits.

Beyond the claim cost, you face state penalties. New York fines employers $2,000 per 10-day period of non-compliance. California imposes a penalty equal to twice the premium the sub should have paid, with a minimum of $1,500. Florida issues stop-work orders that halt your entire project.

Can a GC Be Liable for a Sub's Injured Worker?

Yes, through three pathways.

Statutory employer. In 38 states, the GC is the statutory employer of sub employees. If the sub has no WC, the GC's policy responds.

Contractual liability. Your subcontract may include indemnification language requiring you to defend and indemnify the sub for workplace injuries. Poorly drafted indemnification clauses can make you responsible even when the sub carries WC.

Third-party negligence. The injured worker files a WC claim against their employer (the sub) and files a separate negligence lawsuit against you for unsafe site conditions. This dual-track approach is legal in all 50 states. The WC claim pays medical and wage benefits. The negligence suit seeks additional damages for pain and suffering.

What Is the Difference Between WC and Employer's Liability?

They appear on the same policy but serve different purposes.

Workers compensation (Part One) pays statutory benefits to injured workers regardless of fault. The employer does not need to be negligent. The worker does not need to prove the employer did anything wrong. Benefits include medical expenses, lost wages, disability payments, and death benefits. Coverage limits follow state law.

Employer's liability (Part Two) covers lawsuits where the injured worker sues the employer for negligence beyond what WC provides. Three situations trigger employer's liability:

Dual capacity. The employer acts in a second role (such as equipment manufacturer) and the worker sues under that second role.
Third-party over. A worker sues a third party (the GC), who then sues the sub-employer for contribution.
Consequential injury. A spouse sues the employer for loss of consortium caused by the worker's injury.

Feature	Workers Comp (Part One)	Employer's Liability (Part Two)
Trigger	Any work injury or illness	Negligence lawsuit
Fault required	No	Yes
Benefit type	Statutory (medical, wages, disability)	Damages (varies by lawsuit)
Limits	Set by state law	Policy limits ($100K-$1M typical)
Who files	Injured worker (claim)	Injured worker or GC (lawsuit)
Exclusive remedy	Yes (blocks most lawsuits)	No (covers lawsuits not blocked)

How Does WC Interact with OSHA Citations?

OSHA and WC operate on separate tracks, but they intersect in ways that affect GCs.

OSHA investigates safety violations. If a worker falls from a scaffold missing guardrails, OSHA cites the employer for the guardrail violation. The fine is $16,131 per serious violation (2025 rate). A willful violation costs $161,323.

WC pays the injured worker. The same fall generates a WC claim. The worker receives medical treatment and lost wages through WC, regardless of whether OSHA issues a citation.

The intersection for GCs. An OSHA citation on your project creates documentation that the injured worker's attorney uses in a negligence lawsuit against you. The citation is evidence that you (or your sub) failed to maintain safe conditions. This is how a $42,000 WC claim can lead to a $500,000+ negligence verdict.

OSHA can also cite GCs directly under the multi-employer worksite doctrine. If you had the authority to correct the hazard or created the hazard, OSHA cites you even though the injured worker was not your employee.

Does WC Apply to 1099 Workers?

Not by default. True independent contractors carry their own insurance or choose to go uninsured. WC statutes cover employees, not independent contractors.

The problem is classification. States apply economic reality tests or ABC tests to determine whether a worker is truly independent. In California's ABC test, a worker is an employee unless the hiring entity proves three factors:

A: The worker is free from control and direction
B: The worker performs work outside the usual course of the hiring entity's business
C: The worker has an independently established trade or business

Construction workers almost always fail prong B because their work is within the GC's usual course of business. This makes most construction 1099 relationships suspect.

If a state reclassifies a 1099 worker as an employee, the GC owes back WC premiums, payroll taxes, and penalties. California's Assembly Bill 5 increased enforcement, resulting in over 4,300 construction misclassification findings in 2023 alone.

What About Out-of-State Workers?

WC coverage must match the state where the injury occurs. A sub based in Texas whose worker gets hurt on your Georgia project needs WC coverage that meets Georgia requirements.

Three policy provisions address multi-state work:

Item 3A: Lists the states where the sub has employees. Coverage applies to injuries in those states.

Item 3C (Other States): Extends coverage to states not listed in 3A. If the sub's worker travels to an unlisted state, 3C picks up coverage. However, 3C typically excludes monopolistic fund states (OH, ND, WA, WY).

Separate monopolistic state policies: If work occurs in Ohio, North Dakota, Washington, or Wyoming, the sub needs a separate policy from that state's fund.

Verify your sub's WC policy covers every state where your project operates. Request the declarations page and confirm Item 3A and 3C entries.

WC Verification Checklist for GCs

Use this checklist for every subcontractor, every project.

Checkpoint	Action	When
Certificate on file	Collect ACORD 25 or state fund certificate	Before contract signing
Policy dates	Confirm coverage spans project duration	Before mobilization
Class codes	Match codes to scope of work	Before mobilization
EMR check	Request current EMR, review 3-year history	During prequalification
Officer exclusions	Review endorsement pages for excluded owners	Before mobilization
State coverage	Verify coverage for project state(s)	Before mobilization
Waiver of subrogation	Confirm endorsement is attached	Before mobilization
Expiration monitoring	Set alerts for 30, 14, 7 days before expiry	Ongoing
Cancellation tracking	Monitor for mid-term cancellations	Ongoing
Annual audit prep	Compile all sub certificates for your carrier	At audit

Tracking these checkpoints across 20, 50, or 100 active subs demands a system. SubcontractorAudit automates every line item on this checklist and alerts you when any sub falls out of compliance.

Frequently Asked Questions

What is the exclusive remedy rule in workers compensation? The exclusive remedy rule prevents employees from suing their employer for workplace injuries. WC benefits are the employee's sole compensation from their employer. However, employees can still sue third parties (like GCs or equipment manufacturers) for negligence. The exclusive remedy applies only to the direct employer-employee relationship.

How long does a workers compensation claim stay on a contractor's record? WC claims affect the experience modification rate (EMR) for three years after the claim year, with a one-year buffer. A claim from 2024 enters the EMR calculation in 2025 and stays through the 2027 calculation year. The financial impact diminishes each year as the claim moves further into the experience period.

Can a worker receive both WC benefits and sue the GC? Yes. A worker files a WC claim against their employer (the sub) for medical and wage benefits. Separately, the worker sues the GC for negligence if unsafe job site conditions contributed to the injury. The WC claim and the negligence lawsuit proceed on parallel tracks. Many states require the negligence verdict to reimburse the WC carrier for benefits already paid.

What is the penalty for not carrying workers compensation in construction? Penalties range from $1,000 to $50,000 per violation depending on the state. New York treats it as a criminal offense with fines and potential imprisonment. California imposes double the unpaid premium with a $1,500 minimum. Florida issues stop-work orders and fines of $1,000 per day. Most states also hold the employer personally liable for all claim costs.

How does workers compensation differ from general liability insurance? WC covers injuries to the employer's own workers (first-party coverage). General liability covers injuries to third parties like the public, other contractors' workers, or property damage (third-party coverage). Both are required on construction projects but serve different functions. A sub's employee who falls gets WC benefits. A pedestrian injured by falling debris files a general liability claim.

Do all states require workers compensation for construction? Texas is the only state where WC is technically optional for private employers. However, even in Texas, most project owners and GCs contractually require WC from all subs. The remaining 49 states mandate WC coverage for employers meeting minimum thresholds (typically 1 or more employees in construction). Federal projects require WC regardless of state law.
