If you have even one employee in California, yes, you need workers compensation insurance. California requires every employer to carry it from the very first worker under Labor Code section 3700, with no minimum headcount, no payroll minimum, and no exception for part-time, seasonal, temporary, or farm workers. The real questions are how owners are treated and how to buy it, not whether the rule applies to you.
Who this is for: Any California employer, from a brand-new business making its first hire to an established company double-checking the rules for its mix of staff.
The short version
- Coverage is required from employee number one; there is no headcount trigger and no payroll minimum.
- Part-time, seasonal, and temporary workers all count, and so do farm workers, because California has no agricultural exemption.
- Owners are handled by type: sole proprietors, and an officer who is a corporation's sole shareholder, are out unless they opt in, while other officers, partners, and LLC managing members are in by default.
- Going without coverage exposes you to a stop order, a penalty of 1,500 dollars per employee, and criminal charges.
- You buy from private carriers or the State Compensation Insurance Fund, which is also the guaranteed backstop if you are declined.
Who counts as an employee
California defines an employee broadly: almost everyone in your service under any hiring arrangement counts, and coverage attaches at the first one. There is no group of workers you can add without triggering the rule.
| Worker type | Counts toward the mandate? | Notes |
|---|---|---|
| Full-time W-2 employee | Yes | Coverage required from day one |
| Part-time or seasonal worker | Yes | No hours or headcount exception |
| Temporary or on-call worker | Yes | Still an employee for coverage |
| Farm or agricultural worker | Yes | California has no agricultural exemption |
| A genuine independent contractor | No | Only if they pass the state's strict three-part ABC test |
How California treats business owners
Owners are the one place the answer changes with your structure. A sole proprietor with no employees is not an employee of the business and is not required to carry coverage, though they may elect to include themselves. An officer or director who is the sole shareholder of a corporation is treated the same way, out by default and free to elect coverage to insure their own injuries. Other corporate officers and directors, general partners, and LLC managing members are the opposite: California counts them as covered employees by default when they work for pay, and each can be left off only by signing a written waiver, under penalty of perjury, that goes to the insurer. Either way, the moment you have one non-owner employee, the coverage duty is on.
Why the rule is strict here
California backs the mandate with real teeth. An employer found working without coverage can be served a stop order that halts all use of employee labor immediately, hit with a penalty of 1,500 dollars per employee, and charged with a misdemeanor. On top of that, an injured worker at an uninsured business can sue in civil court, where the law presumes the injury was the employer's fault and strips away the usual defenses. Carrying a policy is what turns comp into the worker's exclusive remedy and keeps that lawsuit off the table.
A Fresno example
Illustrative, not a quote. A Fresno bakery owner hires two counter staff and one part-time weekend baker and assumes part-timers might not count until she has more of them. In California they count from the first one, so she needs a policy right away. She puts coverage in place before anyone starts, and when the weekend baker burns a hand on a hot tray, comp pays the medical bills and part of the lost wages. Because she was insured, the injury is handled as a comp claim rather than a lawsuit she would have to defend, and we make sure her bakery payroll is rated on the right kind of work.
Real questions California owners ask
Is workers comp legally required for my California business?
Yes, if you have any employees. California requires coverage from the first worker under Labor Code section 3700. There is no minimum headcount, no payroll minimum, and no part-time or seasonal exception.
How many employees before I need workers comp in California?
One. California attaches the requirement to your very first employee, so there is no number you can stay under. A single part-time or seasonal hire is enough to make coverage mandatory.
Do part-time or seasonal workers count in California?
Yes. Part-time, seasonal, temporary, and on-call workers are all employees for coverage. California does not exempt them, so you cannot avoid the requirement by keeping people part-time.
Do I need workers comp for farm or agricultural workers?
Yes. Unlike many states, California has no agricultural exemption. Farm and ranch employees must be covered on the same first-employee basis as any other industry.
Do I have to cover myself as the owner?
It depends on your structure. A sole proprietor, or an officer who is a corporation's sole shareholder, is out unless they elect in, while other corporate officers, general partners, and LLC managing members are covered by default and must sign a waiver to opt out.
What if my workers are independent contractors?
Labels do not settle it. California uses a strict three-part ABC test, and a worker is presumed an employee unless you can prove all three parts. Misclassified workers who get hurt can leave you exposed.
What happens if I do not carry it?
You can be served a stop order that halts your labor, penalized 1,500 dollars per employee, and charged with a misdemeanor. An injured worker can also sue you, with the law presuming the injury was your fault.
Why California owners choose Morrow
- We shop the right market for you. In California you buy workers' comp on the open market from any licensed private carrier, with the State Compensation Insurance Fund competing alongside them and standing as the insurer of last resort, so we can shop your rate freely and still have a guaranteed fallback for hard-to-place accounts.
- We catch pricing mistakes. Your price depends heavily on the category your work falls into for pricing (the class code). Put people in the wrong category and you overpay for years. We review your payroll and classifications before you buy.
- Proof of coverage, fast. Need a certificate (proof of coverage) for a general contractor or a landlord before Monday? We turn those around the same business day for most carriers.
- We help lower the score that drives your price. Insurers give you a score based on your past claims that raises or lowers your cost (the experience modification rate). We review it each year, flag errors, and connect you with return-to-work and safety resources that bring it down.
- Real people when a claim happens. When someone gets hurt, we stay involved through the life of the claim, not just at renewal.
