Frequently asked — California workers' comp

Do I need workers' comp if I have only one employee in California?

Yes — California requires workers' comp coverage starting with one employee.

Are 1099 contractors covered under my California workers' comp policy?

Generally no — true independent contractors are not employees and not covered. However, California (like most states) applies an "ABC test" or similar to determine if a 1099 worker is actually a misclassified employee. If they're misclassified, you may owe back premium and penalties. Many general contractors require their 1099 subs to carry their own workers' comp.

Can I get pay-as-you-go workers' comp in California?

Yes — most major carriers offer pay-as-you-go workers' comp in California, with premium based on actual payroll each pay period instead of a large upfront deposit.

What if I'm being audited by my California workers' comp carrier?
