Workers' Comp Requirements by State: Do You Need Coverage?
Workers' compensation insurance is required in almost every U.S. state for businesses with employees. The minimum employee threshold, penalties for non-compliance, and rating bureau vary by state. Here's what you need to know for all 23 states where we're licensed.
The Short Answer: Yes, You Probably Need It
Workers' compensation insurance is mandatory in 49 out of 50 states for businesses that employ workers. Texas is the only state where coverage is fully elective for private employers. If you have employees in any other state, you are legally required to carry workers' comp — and the consequences of non-compliance are severe, including daily fines, stop-work orders, and criminal prosecution.
The key variable is the minimum employee threshold — the number of employees that triggers the requirement. Some states require coverage the moment you hire your first employee, while others don't require it until you reach 3 or 5 employees. Construction businesses face stricter thresholds in many states, often requiring coverage with just one employee regardless of the general threshold.

Understanding Employee Thresholds
The minimum employee threshold determines when your obligation to carry workers' comp begins. There are three common patterns across our licensed states:
1 employee states: California, District of Columbia, Hawaii, Idaho, Massachusetts, Nevada, New Hampshire, Oregon, and Utah require coverage as soon as you hire your first employee. There is no grace period and no exemption for small employers.
3-4 employee states: Arkansas, Georgia, Florida (4 for non-construction), and New Mexico set the threshold slightly higher. However, Florida and several other states drop to 1 employee for construction businesses specifically.
5 employee states: Missouri and Tennessee don't require coverage until you reach 5 employees for most industries, but both states require coverage with just 1 employee for construction and mining operations.
All-employer states: Arizona, Colorado, Illinois, Kansas, New York, Oklahoma, and Pennsylvania require coverage for all employers regardless of size, with no minimum employee threshold.
The Texas Exception
Texas is the only state in the country where private employers can legally choose not to carry workers' compensation insurance. Employers who opt out are called "non-subscribers." However, opting out comes with significant legal risk — non-subscribers lose the protection of the exclusive remedy doctrine, meaning injured employees can sue directly for damages. They also cannot use common legal defenses like contributory negligence or assumption of risk. For this reason, many Texas employers carry coverage voluntarily, and we recommend getting a quote to understand your options.
Construction Gets Special Treatment
Several states impose stricter requirements for construction businesses. Florida, Missouri, and Tennessee all have lower employee thresholds specifically for construction contractors. California's CSLB now requires workers' comp class codes on contractor license renewals. If you're in construction, assume you need coverage — the thresholds are lowest, the penalties are steepest, and general contractors universally require certificates of insurance from every subcontractor on a job site.
Penalties Are Not Worth the Risk
Operating without required workers' comp coverage exposes your business to severe consequences. Across our 23 licensed states, penalties include daily fines ranging from $50 to $1,000 per day, stop-work orders that shut down your business entirely, criminal charges including misdemeanor and felony prosecution, and personal liability for all employee injury costs including medical bills, lost wages, and potential lawsuits. In California, fines can reach $100,000. In New York, intentional non-compliance is a felony. The cost of a workers' comp policy is almost always a fraction of the cost of a single penalty or uninsured claim.
NCCI vs. Independent Rating Bureaus
Most states use class codes and advisory rates developed by NCCI (National Council on Compensation Insurance). However, some states have independent rating systems. California uses WCIRB (Workers' Compensation Insurance Rating Bureau), which has its own class code structure — including the 2024 food service reclassification that created 6 new restaurant codes. New York, Pennsylvania, Massachusetts, and Texas each have their own independent bureaus with state-specific variations. We handle the classification correctly for every state, so you don't need to worry about which system applies.

Do all states require workers' compensation insurance? +
Almost all states require workers' compensation insurance for businesses with employees. Texas is the only state where coverage is elective for private employers.

What happens if I don't have workers' comp insurance? +
Penalties for operating without required workers' compensation insurance vary by state and can include daily fines ranging from $50 to $1,000 per day, stop-work orders that shut down your business, criminal charges including misdemeanor or felony prosecution, and personal liability for all employee injury costs. In states like California, fines can reach $100,000.
How many employees before I need workers' comp? +
The minimum employee threshold varies by state. States like California, Idaho, Oregon, and Nevada require coverage with just one employee. Other states like Arkansas, Georgia, and New Mexico set the threshold at 3 employees. Missouri and Tennessee require coverage at 5 employees for most industries but just 1 for construction.
Is workers' comp required in Texas? +
No. Texas is the only state where workers' compensation insurance is elective for private employers. However, employers who opt out lose important legal protections — employees can sue directly for workplace injuries, and the employer cannot use common defenses like contributory negligence.
What is the difference between NCCI and independent rating states? +
NCCI (National Council on Compensation Insurance) develops workers' comp class codes and advisory rates used in most states. Independent rating states like New York, Pennsylvania, Massachusetts, and Texas have their own state-specific rating bureaus. California uses WCIRB. The class codes and rates can differ between systems, which is why correct state-specific classification matters.
