Why Workers Comp Requirements Vary by State
Unlike most areas of federal law, workers compensation is almost entirely regulated at the state level. This means the rules — who must be covered, what benefits injured workers receive, and where you buy the insurance — differ significantly from one state to the next.
Most states require workers comp the moment you hire your first employee. But some states set the threshold at 3, 4, or even 5 employees before coverage becomes mandatory. And four states — North Dakota, Ohio, Washington, and Wyoming — run monopolistic state funds, meaning private insurance carriers cannot sell workers comp policies there at all.
Understanding your state's requirements is not optional. Operating without required workers comp can result in immediate stop-work orders, fines of $1,000 to $100,000+, and personal liability for every injured worker's medical bills and lost wages.
Understanding Employee Thresholds
A workers comp threshold is the number of employees that triggers mandatory coverage. Here is how to think about it:
Most states — the moment you hire your first W-2 employee, you are required to have workers comp coverage.
Some states (Georgia, Arkansas, South Carolina) set thresholds at 3-4 employees, giving very small businesses a brief grace period.
Alabama, Mississippi, and Missouri require coverage at 5 employees (for most non-construction businesses).
Important: Construction and trades almost always have stricter requirements than other industries — many states require coverage at employee #1 for contractors, regardless of the general state threshold. Florida, for example, requires 4 employees for most businesses but just 1 for construction.

Monopolistic Fund States: What You Need to Know
In four states, the government has a monopoly on workers compensation insurance. You cannot buy a workers comp policy from a private carrier in these states — you must go through the state fund:
North Dakota
State Fund: ND Workforce Safety & Insurance (WSI)
All ND employers must register with WSI before hiring.
Ohio
State Fund: Ohio Bureau of Workers Compensation (BWC)
Large employers may self-insure; most use BWC.
Washington
State Fund: WA Department of Labor & Industries (L&I)
Some large employers may qualify for self-insurance.
Wyoming
State Fund: WY Department of Workforce Services (DWS)
Register with DWS before starting operations.
Operating in a Monopolistic State?
You still need general liability insurance, commercial auto, and other coverages from a private carrier — only workers comp goes through the state fund. Use ERGO NEXT (powered by NEXT Insurance) for all your other commercial coverages.
Penalties for Operating Without Workers Comp
The risks of operating without required workers compensation are severe and immediate. States do not send warning letters — they can act the same day a complaint is filed.
Stop-Work Orders
Most states can issue immediate stop-work orders that shut your business down until you obtain coverage and pay fines. In California, NY, and FL this is enforced aggressively.
Financial Penalties
Fines range from $1,000 per day in some states to $100,000+ for extended non-compliance. New York charges a $2,000 fine for every 10-day period without coverage.
Personal Liability
In many states, if an employee is injured and you lacked required coverage, you are personally liable for their entire medical bills, lost wages, and potentially a lawsuit with no cap on damages.
Criminal Charges
Willful non-compliance is a crime in many states — a misdemeanor or felony depending on the state and severity. Business owners can face jail time.
How Much Does Workers Comp Cost?
Workers comp premiums are calculated per $100 of payroll using industry class codes. The riskier the work, the higher the rate. Here are typical ranges as of 2026:
| Industry / Job Type | Rate per $100 Payroll | Est. Annual Cost (1 Employee, $50k payroll) |
|---|---|---|
| Clerical / Office Work | $0.20–$0.50 | $100–$250 |
| Retail / Store Work | $1.00–$2.50 | $500–$1,250 |
| Landscaping | $5.00–$8.00 | $2,500–$4,000 |
| Cleaning Services | $3.00–$6.00 | $1,500–$3,000 |
| General Construction | $6.00–$12.00 | $3,000–$6,000 |
| Electrical Contractors | $4.00–$8.00 | $2,000–$4,000 |
| Roofing | $15.00–$25.00 | $7,500–$12,500 |
| Trucking / Delivery | $6.00–$12.00 | $3,000–$6,000 |
