If an employee gets hurt on the job, who pays the medical bills and lost wages? In nearly every state, the answer is your workers’ compensation insurance. This coverage is legally required for most employers, and operating without it can trigger fines, lawsuits, and even criminal charges. Here is what workers’ compensation insurance is, what the requirements look like in 2026, and how to get covered.

What Workers’ Compensation Insurance Is
Workers’ compensation is a no-fault insurance system: when an employee is injured or becomes ill because of their job, the policy pays for medical treatment and a portion of lost wages regardless of who caused the accident. In exchange, employees generally give up the right to sue the employer for the injury — a trade-off known as the “exclusive remedy” rule that protects businesses from large negligence lawsuits.
The system dates back more than a century and is administered state by state, so the rules differ across the country. But the core bargain is the same everywhere: fast, predictable benefits for injured workers and predictable, limited liability for employers. For a small business, one serious injury without coverage could be financially devastating, which is why the mandate exists.
What It Covers (and What It Does Not)
A standard policy covers medical expenses for work-related injuries and illnesses, a percentage of lost wages while the employee recovers (typically around two-thirds of average weekly wages, subject to state caps), rehabilitation costs, and death benefits paid to dependents in fatal cases. It also covers the employer’s legal defense if a claim is disputed.
It does not cover injuries that happen off the job, injuries caused by intoxication or intentional self-harm, or claims by independent contractors — which is one more reason correct 1099 vs. W-2 worker classification matters. Commuting injuries are generally excluded, though the rules get nuanced for employees who travel as part of their duties.
Who Must Carry It: State Requirements
Almost every state requires employers to carry workers’ compensation insurance, but the trigger varies. Many states require coverage from the very first employee; others set thresholds like three or five employees. Texas is the notable exception — coverage is generally optional there, though employers who opt out lose important legal protections.
Common exemptions include sole proprietors and partners with no employees (though they can often opt in), some agricultural and domestic workers, and in certain states, corporate officers who formally elect out. Construction businesses face stricter rules in many states, sometimes requiring coverage even for owners. Because requirements are state-specific, check your state’s workers’ compensation board — the USA.gov state agency directory links to each state’s labor and insurance programs.
How Much It Costs
How Much It Costs
Premiums are based on your payroll, your industry’s risk classification, and your claims history. Insurers assign class codes to job duties — a clerical worker costs far less to insure than a roofer — and multiply the rate per $100 of payroll by your total payroll in each class. Your experience modification factor then adjusts the premium up or down based on your actual claims versus expected claims for your industry.
As a rough sense, low-risk office businesses often pay well under 1 percent of payroll, while high-risk trades can pay several percent or more. A clean safety record, documented safety training, and a return-to-work program can lower your modifier over time. Pay-as-you-go billing, where premiums are calculated from actual payroll each cycle instead of estimated annual payroll, helps cash flow and avoids a surprise audit bill at year-end.
How to Buy a Policy
Start with a licensed insurance agent or broker who works with small businesses in your state. Get quotes from multiple carriers, because rates for the same class codes can differ significantly. You will need your FEIN, a description of job duties, payroll estimates by class, and your claims history. Some states operate a state fund or assigned-risk pool for businesses that cannot find private coverage.
Review the policy’s class codes carefully — misclassification is a common and expensive error, and insurers audit payroll annually to correct it. If your business changes (new services, new roles), tell your insurer promptly so the codes and payroll estimates stay accurate.
What Happens When a Claim Is Filed
When an injury occurs, provide first aid, then document the incident and report it to your insurer promptly — most states set strict reporting deadlines, sometimes as short as a few days. The insurer investigates, authorizes treatment, and pays benefits according to the state’s schedule. You should cooperate fully and keep the employee informed throughout.
Having a written injury-reporting procedure and a designated contact person prevents delays. Return-to-work programs that offer light duty during recovery reduce both the human and financial cost of claims, and they feed directly into a better experience modifier at renewal. Pair this with a solid new-hire onboarding process so safety training happens before anyone’s first shift.
