Workers compensation insurance pays for an employee's medical treatment, lost wages, and rehabilitation costs when they suffer a work-related injury or illness — and protects the employer from being sued for those injuries in most states. Nearly every state requires it the moment you hire your first W-2 employee. Who this is for: any business owner with employees, from a single-location contractor to a multi-state manufacturer.
TL;DR — Key Takeaways
- Legally required in 49 states the moment you hire employees (Texas is the main opt-out state for private employers; monopolistic-state-fund states like Wyoming, Ohio, North Dakota, and Washington still require coverage but only through the state fund; rules vary — [verify state]).
- Covers four core costs: medical bills, lost wage replacement (typically 66⅔% of the worker's average weekly wage), permanent disability benefits, and death/survivor benefits.
- Does not cover employer negligence lawsuits above the exclusive-remedy limit — that gap is filled by Employers Liability (Part B of a standard workers comp policy).
- Premium is primarily driven by payroll, job classification (NCCI class codes), and your Experience Modification Rate (EMR/e-mod), not your revenue or assets.
- COIs and waivers of subrogation can be issued same-day through Morrow for most carriers.
What Does Workers Compensation Insurance Cover?
A standard workers compensation policy in the United States is divided into two parts:
Part A — Workers Compensation (statutory benefits): Pays benefits defined by each state's workers compensation statute — no per-occurrence dollar limit. The insurer pays whatever the law requires.
| Benefit Type | What It Pays | Typical Limit / Formula |
|---|---|---|
| Medical expenses | All reasonable, necessary treatment for the work injury | Unlimited (state fee schedule may cap unit costs) |
| Temporary total disability (TTD) | Lost wages while completely unable to work | ~66⅔% of average weekly wage; state max caps apply |
| Temporary partial disability (TPD) | Wage difference during light-duty return to work | Varies by state |
| Permanent partial disability (PPD) | Lump sum or weekly benefit for lasting impairment | Rated by impairment schedule or loss-of-earning-capacity |
| Permanent total disability (PTD) | Ongoing wage replacement for catastrophic injury | Life-time benefit in many states |
| Death / survivor benefits | Burial costs + weekly survivor payments | Burial: typically $5,000–$15,000; survivor: % of wage |
| Vocational rehabilitation | Retraining costs if worker can't return to prior job | State-mandated; no hard dollar cap in most states |
Part B — Employers Liability: Covers lawsuits by employees (or their families) that fall outside the exclusive-remedy bar — for example, "dual capacity" suits, third-party-over actions, or claims by spouses for loss of consortium. Standard limits are $100,000 per occurrence / $100,000 per employee (disease) / $500,000 policy aggregate, though these are routinely increased to $1M/$1M/$1M for contractors and companies with upstream contract requirements.
What Workers Comp Does NOT Cover
- Injuries to independent contractors (1099s) — a frequent audit issue
- Intentional self-inflicted injuries
- Injuries while committing a crime or under the influence (state law varies on how this is handled)
- EPLI (employment discrimination, harassment) claims — that requires a separate Employment Practices Liability policy
How Much Does Workers Compensation Insurance Cost?
Premium is calculated on a payroll basis, not revenue. The core formula:
Premium = (Payroll ÷ 100) × Class Code Rate × Experience Mod (EMR)
Class code rate is set by the NCCI (National Council on Compensation Insurance) in most states, or by an independent state rating bureau (e.g., California's WCIRB, New York's NYCIRB). Rates are expressed per $100 of payroll.
| Industry / Trade | NCCI Class Code (example) | Approximate Rate per $100 Payroll | Annual Premium — $500K Payroll |
|---|---|---|---|
| Clerical / office workers | 8810 | $0.15–$0.40 | $750–$2,000 |
| Retail store | 8017 | $1.00–$2.00 | $5,000–$10,000 |
| Restaurant / food service | 9082 | $2.00–$4.00 | $10,000–$20,000 |
| General contractor (residential) | 5651 | $8.00–$14.00 | $40,000–$70,000 |
| Roofing | 5551 | $20.00–$35.00+ | $100,000–$175,000+ |
| Electrical (commercial) | 5190 | $4.00–$8.00 | $20,000–$40,000 |
| Plumbing | 5183 | $5.00–$9.00 | $25,000–$45,000 |
| Trucking (long-haul) | 7229 | $8.00–$15.00 | $40,000–$75,000 |
| Nursing / home health aide | 8835 | $7.00–$13.00 | $35,000–$65,000 |
Rates shown are illustrative ranges based on NCCI loss-cost filings and common surcharges; actual rates vary by state, carrier, and individual risk. [Morrow to confirm] final rates for your account.
The Experience Modification Rate (EMR)
Your EMR compares your actual loss history to the expected losses for businesses of your type and size. An EMR of 1.00 is industry average. An EMR of 0.80 means a 20% premium credit; an EMR of 1.30 means a 30% surcharge. A clean loss history is the single most powerful lever to reduce workers comp cost over time.
Premium Audit
Workers comp policies are almost universally audited at expiration. The carrier reconciles estimated payroll against actual payroll, and you receive a return premium or additional premium invoice. Misclassifying employees in lower-rated codes is a common audit finding — and misclassification is a compliance violation, not just a billing error.
Is Workers Compensation Insurance Required for Your Business?
| State Type | Rule |
|---|---|
| Mandatory states (most states) | Required as soon as you have 1 W-2 employee |
| Threshold states | Required at 2, 3, or 5 employees depending on state [verify state] |
| Texas | Coverage is optional for private employers (but required for public contractors) |
| Federal employees | Covered under FECA (Federal Employees' Compensation Act), not a private policy |
| Sole proprietors / partners | Generally excluded but can elect to be covered; many contracts require it |
Penalties for non-compliance include state fines, stop-work orders, personal liability for all injury costs, and criminal charges in several states.
How to Get Workers Compensation Insurance in 5 Steps
- Gather your payroll data by job function. Break down estimated annual payroll by employee type (clerical, field, drivers, etc.). Misclassifying roles is the top audit surprise.
- Identify your NCCI class codes. Your broker will assign codes, but understanding them helps you flag misclassifications early.
- Pull your loss run reports. Request 5 years of loss history from your current or prior carrier. Underwriters require this for any account above a minimum premium threshold (often $5,000–$10,000).
- Submit to multiple carriers. An independent broker like Morrow can market your account simultaneously to multiple admitted and E&S carriers, including monoline workers comp specialists.
- Review the policy declarations and Part B limits. Confirm employers liability limits meet your upstream contract requirements before binding.
Real-World Example: Roofing Contractor in Florida
This is an illustrative scenario, not a guarantee of outcomes.
The business: A residential roofing company in Tampa, FL with 12 employees and $1.2M in annual payroll. Owner has a clean 3-year loss history and an EMR of 0.87.
The incident: A laborer falls from a second-story roofline, suffering a broken femur, torn ACL, and a six-month recovery. Total claim: $94,000 in medical bills and $31,000 in TTD wage replacement.
What workers comp paid: - Medical treatment (surgery, PT, follow-up): $94,000 — paid in full under Part A (no deductible in Florida for medical) - TTD at 66⅔% of his $1,100/week wage = $733/week × 26 weeks = $19,058 - Permanent impairment rating of 7% to the lower extremity → PPD lump-sum settlement: ~$12,000
Total claim cost to carrier: ~$125,000. The employer paid $0 out of pocket on the claim (no deductible policy). Had the employer been uninsured, Florida statutes would have made the business owner personally liable for all costs plus state penalties.
The employee's attorney filed a third-party suit against the scaffolding manufacturer. The carrier's subrogation unit recovered $38,000, reducing the carrier's net loss — which directly benefits the employer's future EMR calculation.
Frequently Asked Questions
Does workers compensation cover independent contractors?
Generally no. Workers comp covers W-2 employees. Independent contractors (1099 workers) are typically excluded — but classification is often disputed. If a state labor agency or the IRS reclassifies a 1099 worker as an employee (applying the ABC test or common-law test), your workers comp policy may not cover them retroactively, and you could face back-premium liability. When in doubt, have your broker review contractor relationships before policy inception.
What is an experience modification rate (EMR) and how does it affect my premium?
Your EMR (also called e-mod) is a multiplier calculated by the NCCI or your state's rating bureau based on your actual claims history compared to businesses of similar size and type. A 1.00 is average. An EMR below 1.00 saves you money; above 1.00, you pay a surcharge. Most general contractors are contractually required to maintain an EMR below 1.0 or 1.25. Improving safety practices, returning injured workers to modified duty quickly, and managing claims aggressively all drive the EMR down over a 3-year rolling window.
Can I get workers comp if I've had large claims in the past?
Yes, but you may be placed in the state's assigned risk pool (residual market) or with a specialty carrier at higher rates. Admitted carriers typically want 3–5 years of loss runs and may decline accounts with frequency problems (multiple small claims) even if the total paid losses are modest. Morrow works with specialty market carriers who underwrite difficult-to-place accounts.
What's the difference between workers comp and general liability for employee injuries?
Workers compensation covers your employees' on-the-job injuries — it's a no-fault system. General liability insurance covers third-party bodily injury (customers, visitors, bystanders), not your own workers. If a customer trips and falls in your store, that's a GL claim. If your employee trips and falls in your store, that's a workers comp claim.
Does workers comp cover occupational diseases, not just accidents?
Yes. Part A covers occupational diseases — illnesses arising from conditions peculiar to the work, such as asbestosis, hearing loss from industrial noise, repetitive stress injuries (carpal tunnel), and chemical exposure illnesses. Latency periods and statute-of-limitation rules vary significantly by state.
What is a waiver of subrogation on a workers comp policy?
A waiver of subrogation (WOS) prevents your workers comp carrier from seeking reimbursement from a third party — such as a general contractor — after paying a claim involving that third party's negligence. General contractors routinely require subcontractors to carry a blanket WOS endorsement. There is typically a small additional premium charge, and the WOS must be in place before an injury occurs to be effective.
How quickly do I need to report a workplace injury?
Most states require the employer to file a First Report of Injury (FROI) within 5–10 days of the injury, and some require immediate notification of fatalities. Your policy also has prompt-reporting obligations — late reporting can jeopardize coverage and increase claim costs. Establish an internal reporting procedure before you need it.
Does a small business with only one employee need workers comp?
In most states, yes — one W-2 employee triggers the coverage requirement. Sole proprietors, partners, and LLC members are often excluded by default but may elect coverage. Many upstream contracts (e.g., from a GC to a subcontractor) require workers comp regardless of employee count. [verify state] for the threshold applicable to your state and industry.
