In California, failing to carry required workers compensation is illegal and carries some of the toughest penalties in the country. If you have employees and no coverage, the state can immediately halt your business, assess penalties measured per employee, and pursue criminal charges, and an injured worker can sue you directly. This is not a paperwork violation; it is treated as a serious offense.
Who this is for: California employers weighing the risk of going without coverage, and owners who have let a policy lapse and want to understand their real exposure.
The short version
- Being uninsured with employees is a misdemeanor in California, not a minor infraction.
- The state can serve a stop order that halts all use of employee labor immediately.
- Civil penalties run 1,500 dollars per employee, and more if you were uninsured for over a week or a claim arose.
- An injured worker can sue you, and the law presumes the injury was your fault while removing your defenses.
- For licensed contractors, letting coverage lapse suspends the state contractor license automatically.
The stop order comes first
When the state finds an employer working without required coverage, the Director of Industrial Relations can serve a stop order that prohibits the use of employee labor right away, effective the moment it is served. You cannot keep operating with staff until you secure coverage, and your affected employees are entitled to pay for the time lost, up to 10 days, while you comply. Ignoring the stop order is itself a separate misdemeanor, punishable by jail and a fine. In practice, a stop order can shut a job site or a storefront down on the spot.
The penalties that stack
| Consequence | What it is | Rough amount |
|---|---|---|
| Stop order | Halts all use of employee labor until you get coverage | Immediate; workers get up to 10 days of lost-time pay |
| Per-employee penalty | Assessed when the stop order is served | 1,500 dollars per employee |
| Uninsured-period penalty | If you were uninsured over a week in the prior year | The greater of twice the premium owed or 1,500 dollars per employee |
| Claim penalty | If a covered injury happened while you were uninsured | An extra 10,000 dollars per employee (2,000 if the claim is not compensable) |
| Criminal charge | Misdemeanor for failing to secure coverage | The greater of 10,000 dollars or double the premium, or jail up to a year |
The lawsuit and the personal exposure
Beyond the fines, going uninsured strips away your legal protection. An injured employee at an uninsured business can file for benefits, which a state fund may pay and then pursue you to recover, or sue you in civil court. In that lawsuit the law presumes the injury was caused by your negligence, and you cannot argue the worker was careless, knew the risk, or was hurt by a co-worker. Sole proprietors and partners can be personally liable, so a judgment can reach personal assets. The aggregate civil penalties are capped at 100,000 dollars, but that cap leaves out the added penalty for being uninsured more than a week, so the real civil exposure can run higher still, and a single serious injury lawsuit can cost far more than years of premium.
A Stockton example
Illustrative, not a quote. A Stockton roofing company lets its workers comp lapse to save money over a slow winter. A roofer falls and is seriously hurt while the policy is down. The company is served a stop order that halts its crews, assessed 1,500 dollars per employee plus an added 10,000 dollars for the injured worker, and faces a civil claim it cannot defend with the usual arguments, while its contractor license is suspended for the lapse. The combined cost dwarfs the premium it skipped. After the claim, the owner reinstates coverage, and we place a policy and rate the roofing payroll correctly.
Real questions California owners ask
Is it illegal to not have workers comp in California?
Yes, if you have employees. Failing to carry required coverage is a misdemeanor in California, not a minor violation. The state can halt your business, penalize you per employee, and pursue criminal charges.
What is the penalty for not having workers comp in California?
The state can serve a stop order and assess 1,500 dollars per employee, with more if you were uninsured over a week or a claim arose. Criminal fines run to the greater of 10,000 dollars or double the premium.
What is a stop order?
It is an order that prohibits you from using employee labor until you secure coverage, effective immediately when served. Affected workers are owed pay for lost time up to 10 days, and ignoring it is a separate crime.
Can I be sued if a worker is hurt and I have no coverage?
Yes. An injured worker can sue you in civil court, where the law presumes the injury was your fault and removes the defenses that the worker was careless, knew the risk, or was hurt by a co-worker.
Can the penalties reach my personal assets?
They can. Sole proprietors and partners can be personally liable, so a judgment or penalty can reach personal assets. A state fund that pays an uninsured claim can also pursue you to recover it.
Does a lapse affect my contractor license?
Yes. For a licensed contractor, failing to maintain required workers comp suspends the state contractor license automatically, which can stop you from working until coverage and the license are restored.
Is going without coverage cheaper than carrying it?
Only until something goes wrong. Skipping premium saves money short term, but one stop order, the stacked per-employee penalties, and a single injury lawsuit can cost far more than years of coverage.
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.
