Many business owners assume workers’ compensation only applies to large companies or physically demanding industries like construction. In California, that assumption can be costly. The law is broader and stricter than most employers expect.
Do I need workers’ compensation insurance in California?
Yes. California requires virtually all employers with at least one employee, full-time, part-time, or seasonal, to carry workers’ compensation insurance. There is no exception based on business size. Some narrow exceptions exist, such as sole proprietors with no employees, and certain corporate officers who may elect to exclude themselves under specific ownership conditions. Outside of those limited cases, coverage is mandatory from the moment you hire your first employee.
What does workers’ compensation insurance typically cover?
Depending on the policy and the circumstances of the claim, workers’ compensation may help cover:
• Medical treatment related to a job injury or illness
• Temporary disability payments while an employee recovers
• Permanent disability benefits, if applicable
• Supplemental job displacement benefits in qualifying situations
• Death benefits for dependents in the case of a fatal workplace incident
What happens if an employer doesn’t have coverage?
California takes this requirement seriously. The Department of Industrial Relations can issue a stop order, which legally prohibits a business from operating until coverage is obtained. Beyond fines, an employer without coverage can become personally responsible for an injured employee’s medical bills and lost wages, costs that would otherwise have been covered by insurance. In certain cases, criminal penalties may also apply.
How are workers’ compensation rates determined?
Several factors typically influence premiums, including your industry classification code, total payroll, and claims history, often reflected in what’s called an Experience Modification Rate, or X-Mod. A business with a strong safety record may see lower rates over time, while frequent claims can increase costs.
Are business owners and officers covered under workers’ compensation?
This depends on business structure. Corporate officers may be able to elect exclusion from coverage if they meet certain ownership requirements. Sole proprietors and partners are generally not required to carry coverage for themselves, though many choose to opt in for their own protection. LLC members face similar considerations, and the right approach depends on how the business is structured.
What about independent contractors?
Worker classification has become an increasingly important issue in California, particularly following AB5. If a worker is functioning like an employee regardless of their title, misclassifying them as an independent contractor can create liability, including potential workers’ compensation exposure, even if no formal payroll relationship exists.
How can employers manage workers’ compensation costs?
A few practical steps can help over time:
• Maintaining accurate payroll records and job classifications
• Investing in workplace safety programs to reduce claims
• Reviewing coverage periodically as the business grows or changes
• Working with an agent to ensure class codes reflect actual job duties, not outdated classifications
Frequently Asked Questions
Does a part-time employee require workers’ compensation coverage?

Can a small business with one employee skip workers’ compensation insurance?

Does workers’ compensation cover remote employees?
In many cases, yes. If the injury or illness is job-related, even employees working remotely may be covered, though specifics depend on the policy and circumstances.
