Workers’ compensation, which can provide cash and medical care to employees injured on the job, and benefits to survivors in cases of a work-related death, began with a federal program in 1908. It gave benefits to civilian workers whose jobs were hazardous and became the first kind of social insurance established across the United States.

By 1916, the rest of the federal workforce was covered. States meanwhile were enacting their workers’ compensation laws. All but six states and the District of Columbia had them by 1921.

Today, programs exist in all 50 states, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands.

The details of each program vary by state. Four states—Ohio, North Dakota, Washington and Wyoming—require insurance be obtained through a state-administered fund rather than through a private insurer. Another option is to self-insure for approved businesses. Most states require some businesses to provide coverage and can levy substantial fines for failing to comply. South Dakota and Texas leave the choice to businesses, although Texas makes an exception for construction companies with a government contract.

Simply Business reviewed rules, statistics, and other information about workers’ compensation insurance—including the comprehensive breakdown by the National Federation of Independent Business—to offer a breakdown of what workers’ comp requirements in each state. Rules are subject to updates periodically, so it’s important to stay up-to-date based on your trade and location.
