If you’re a California contractor who is required to carry workers’ comp, a lapse suspends your license automatically on the day coverage ends, and work done after that counts as unlicensed. Any California employer without coverage can also get a stop order that bars using employees, penalties assessed per employee, and possible misdemeanor charges. If someone is hurt during the gap and you don’t pay the award, a state fund pays the worker and the state can then sue you to recover it, and the worker can sue you directly with the law presuming you were negligent. Most of this is avoidable if you act on the cancellation notice before its date and get proof of coverage back to CSLB.
Your contractor license is suspended the day coverage lapses
For a CSLB licensee who is required to carry workers’ comp, Business and Professions Code 7125.2 makes the suspension automatic, by operation of law. It takes effect on the date the coverage lapses, or on the date coverage was first required if that came earlier. The registrar then sends a notice with the reason, the effective date and the steps to reinstate.
CSLB doesn’t wait for you to tell it. Under B&P 7125, every workers’ comp insurer, including State Fund, reports each contractor’s policy to the registrar with the dates coverage starts and lapses and any cancellation date. CSLB says any work performed while the license is suspended is considered unlicensed, and you may not contract for work with a suspended license.
The cancellation notice gives you a short window
Once a California workers’ comp policy is in force, the insurer can cancel it only for the reasons listed in Insurance Code 676.8. Nonpayment of premium, failing to report payroll or allow an audit, a material misrepresentation, or failing to cooperate on a claim takes 10 days’ written notice to you. Material noncompliance with safety orders or the insurer’s written loss control recommendations, a material change in ownership, or a change in operations that materially increases the hazard takes 30 days.
If you remedy the condition to the insurer’s satisfaction within that notice period, Insurance Code 676.8 says the insurer can’t cancel the policy. Payroll audits are on the list; here is how a premium audit works.
Stop orders and state penalties
The Labor Code applies to every California employer without required coverage, licensed or not. Under section 3710.1, the state issues and serves a stop order barring the use of employee labor until you get coverage; DIR says the Division of Labor Standards Enforcement issues them. It takes effect on service, and you must pay idled employees for lost time, up to 10 days. You can request a hearing within 20 days. Ignoring a stop order is a separate misdemeanor under section 3710.2: up to 60 days in county jail, a fine up to $10,000, or both.
Under section 3722, a penalty assessment order is issued and served along with the stop order: $1,500 per employee employed at that time. If you were uninsured for more than a week in the preceding calendar year, it becomes the greater of twice the premium you would have paid for the uninsured period or $1,500 per employee employed during it. If an injured worker files a claim and the Workers’ Compensation Appeals Board finds you were uninsured, you are assessed $10,000 per employee employed on the date of injury if the claim is compensable, or $2,000 per employee if it isn’t. Section 3722 penalties are capped at $100,000, except the penalty for being uninsured more than a week.
If someone gets hurt during the gap
The worker still gets benefits. When an illegally uninsured employer doesn’t pay a WCAB award within 10 days of notice, the Uninsured Employers Benefits Trust Fund pays it (Labor Code 3716). The state can then come after you: section 3717 lets the director sue to recover the award plus interest, costs, attorney fees and investigation and litigation expenses, and when the employer is a corporation, its parent and shareholders holding at least 15 percent can be held jointly and severally liable.
The worker can also sue you in civil court as if the workers’ comp system didn’t apply (section 3706). In that suit, section 3708 presumes the injury came from your negligence and puts the burden on you to rebut it. You can’t argue the worker was partly at fault, assumed the risk, or was hurt by a co-worker’s negligence.
Going without required coverage when you knew, or with your experience should have known, that you needed it is a misdemeanor under section 3700.5: up to a year in county jail, a fine of up to double the premium that should have been paid but not less than $10,000, or both. A second conviction carries up to a year in jail and a fine of triple the premium, not less than $50,000.
What to do the day the notice arrives
- Read the reason and the date. If it is nonpayment or a missing payroll report, fixing it to the insurer’s satisfaction before the cancellation date keeps the policy from being cancelled.
- Call me or your carrier the same day. If the policy is saved, the insurer sends CSLB a reinstatement notice to rescind the cancellation. If the policy expired, it sends a renewal notice.
- If it can’t be saved, put a new policy in place before the old one ends. Under B&P 7125.1, CSLB accepts a new certificate as of its effective date if it arrives within 90 days of that date, and reinstates the license, if otherwise eligible, retroactively to that date. Any days between the lapse and the new policy’s start are still a gap.
- Hold off on contracting and on using employees until coverage is back. CSLB lifts the suspension once acceptable proof of coverage is received and processed at its headquarters.
If you truly have no employees, an exemption may be the right filing instead; see who is exempt from workers’ comp in California. C-8, C-20, C-22, C-39 and C-61/D-49 tree service licensees can’t file an exemption. The current version of B&P 7125 is set to be repealed on January 1, 2028; read what changes for contractors in 2028 or check whether it applies to you.

Common questions
Is my contractor license suspended right away?
Yes. Under B&P 7125.2 the suspension is automatic by operation of law and takes effect on the date your workers’ comp coverage lapses.
Is reinstatement retroactive?
To the new certificate’s effective date, if CSLB receives it within 90 days of that date (B&P 7125.1). Days between the lapse and that effective date are still a gap, and if the certificate arrives later, CSLB must still accept it as of that date if you show, on a form CSLB accepts, that the delay was due to circumstances beyond your control.
How much notice does my insurer have to give before cancelling?
Ten days for nonpayment, failing to report payroll or allow an audit, misrepresentation, or not cooperating on a claim. Thirty days for safety noncompliance, a material change in ownership, or a change in operations that materially increases the hazard, under Insurance Code 676.8.
Can an injured worker sue me if I had no coverage?
Yes. Labor Code 3706 allows a civil suit, and section 3708 presumes you were negligent and takes away defenses like the worker’s own fault. The worker can also file a workers’ comp claim, which a state fund may pay if you don’t, and the state can then sue you to recover it.
Is going without workers’ comp a crime in California?
Yes. Failing to secure coverage when you knew, or should have known, that you had to is a misdemeanor under Labor Code 3700.5, punishable by up to a year in county jail, a fine of at least $10,000, or both. Ignoring a stop order is a separate misdemeanor under section 3710.2.
