Understanding your state's requirements, how premiums are calculated, and ways to control costs can save your business thousands of dollars while ensuring proper protection for your workforce.

What Is Workers Compensation Insurance?

Workers compensation insurance provides coverage for employees who suffer work-related injuries or illnesses. It covers medical expenses, lost wages, rehabilitation costs, and death benefits, while protecting employers from lawsuits related to workplace injuries.

This no-fault insurance system ensures injured workers receive timely medical care and compensation without having to prove employer negligence, while employers gain protection from potentially devastating lawsuits.

How to Purchase Workers Compensation Insurance

1. Private Insurance Carriers

Most states allow businesses to purchase coverage from private insurance companies. This is often the most flexible option, allowing you to shop for competitive rates and bundle with other business insurance.

Some states operate competitive state funds that offer workers compensation insurance alongside private carriers. States with monopolistic state funds (North Dakota, Ohio, Washington, Wyoming) require you to purchase through the state program.

3. Self-Insurance

Large companies with strong financial resources may qualify for self-insurance programs, assuming the financial risk of workers compensation claims directly.

PEOs can provide workers compensation coverage as part of their co-employment arrangement, often securing better rates through their larger employee pool.

Frequently Asked Questions

Do I need workers comp if I only have part-time employees?

Yes, in most states, part-time employees count toward the employee threshold for workers compensation requirements. The number of hours worked typically doesn't matter—if you have the required number of employees, coverage is mandatory.

Can employees waive workers compensation coverage?

Generally, no. Workers compensation is a statutory requirement that employees cannot waive. However, certain corporate officers and LLC members may be able to exclude themselves from coverage in some states.

What happens if an employee is injured and I don't have coverage?

You become personally liable for all medical costs and lost wages. The employee can also sue you directly for damages, and you'll face state penalties including fines and possible criminal charges. The financial impact can be devastating to a business.

How are remote workers covered?

Remote workers are generally covered for injuries that occur while performing work duties, even at home. However, proving work-relatedness can be more challenging. Clear policies about work hours and workspace requirements are essential.

Can I get workers comp with previous claims?

Yes, but your premiums will likely be higher due to an increased experience modifier. Some carriers specialize in high-risk coverage. Implementing strong safety programs can help offset the impact of past claims over time.

Conclusion

Workers compensation insurance is not just a legal requirement—it's a crucial protection for your business and employees. Understanding your state's specific requirements, how premiums are calculated, and implementing strategies to control costs can help you maintain compliance while managing expenses.
