California Business Insurance Requirements: What You Actually Need
Most California business owners start with the same question: what insurance does a business need in California? The short answer is that state law requires far less than most people expect. There are two major exceptions. The first is workers' compensation, once you have employees. The second is auto liability, if you drive vehicles for the business. Beyond those, your requirements depend on your trade, your licensing board, and the contracts you sign.
This guide covers the california business insurance requirements that apply to most owners, in the order the law generally applies them. This is informational content, not legal or tax advice. Insurance rules and licensing requirements change, and the right answer for your business depends on facts this guide cannot know. Talk to a licensed insurance broker, an attorney, or a CPA before you rely on any of it.
Keep in mind that California has no general state business license. The Secretary of State issues none, and the CDTFA seller's permit is not a business license. Your basic setup is to register your entity with the California Secretary of State, Business Programs Division, register with the CDTFA if you sell taxable goods, register with the EDD if you have employees, and then add the licenses and permits for your activity. Most cities also charge a local business tax or registration certificate. 445 of 483 cities report revenue from one, and there is no common formula, so the answer depends on your city.
The Coverage the Law Requires
Only a few coverages are mandated by California law. Here they are in the order most owners encounter them:
- Workers' compensation, if you have employees.
- Payroll programs (Unemployment Insurance, Employment Training Tax and State Disability Insurance), which are payroll obligations rather than policies you buy.
- Auto liability, if you operate vehicles for the business.
- A contractor's bond, if you hold a contractor's license.
- Professional liability, but only where your licensing board or the rules of your profession require it.
1. Workers' Compensation
Under Labor Code 3700, every employer in California except the state must secure payment of workers' compensation. You can do that in one of two ways: buy a policy from an authorized insurer, or obtain a certificate of consent to self-insure from the Director of Industrial Relations. Self-insurance is uncommon for small businesses, so most owners will buy a policy.
If you have no employees, you are generally not required to cover yourself. If you do have employees, some owners can opt out, but the rules are narrow:
- A corporate officer or director who owns at least 10% of the stock may sign a written waiver, provided they are covered by health insurance (Labor Code 3352(a)(16)). If a parent, grandparent, sibling, spouse or child owns at least 10% of the stock, the threshold drops to 1%.
- A general partner, or an LLC's managing member, may waive coverage by written waiver (Labor Code 3352(a)(17)).
- Working members of an LLC who are paid wages regardless of profits are treated as employees under Labor Code 3351(f), unless they use the managing member waiver.
Once you have coverage, you must post a notice naming your insurance carrier (Labor Code 3550). Make sure your policy covers every employee and that you keep records of any waivers you sign.
What happens if you go without coverage
The penalties are serious. Failing to secure compensation is a misdemeanor if the employer knew or should have known it was required. Under Labor Code 3700.5, the penalty can be up to one year in county jail, a fine of up to double the premium that would have been due but not less than $10,000, or both. A second offense carries a fine of triple the premium, not less than $50,000. The state can also issue a stop order that bars you from using employee labor until you comply (Labor Code 3710.1), along with a penalty of $1,500 per employee (Labor Code 3722).
If you hold a contractor's license, the consequences are faster. Under Business and Professions Code 7125.2, your license is automatically suspended if required workers' compensation lapses. Civil penalties under Business and Professions Code 7125.4 start at $10,000 for a sole owner and $20,000 for other entities.
2. Payroll Programs: UI, ETT and SDI
Three payroll programs come with hiring, and they are often confused with insurance. Employers pay Unemployment Insurance and Employment Training Tax. New employers pay 3.4% UI on the first $7,000 of each employee's wages, plus ETT at 0.1%. State Disability Insurance is different: it is withheld from employee wages at 1.3% in 2026, applied to all wages with no cap. You do not buy SDI and you do not provide it. It is a withholding from your workers' pay.
Register with the EDD before you pay your first employee, and check the EDD website for your filing schedule and new-hire reporting duties.
3. Auto Liability
California requires minimum auto liability coverage of $30,000 for injury or death to one person, $60,000 for injury or death to more than one person in a single accident, and $15,000 for property damage. These are the state minimums, and they are higher than many owners assume, so a personal policy that meets the old minimums may not be enough.
The DMV also accepts other proof of financial responsibility: a $75,000 cash deposit, a DMV self-insurance certificate, or a $75,000 surety bond. Most owners buy a policy from an insurer.
Commercial vehicles and some contracts may require higher limits. Check with your insurer and your customer before you assume the state minimum will satisfy them. Also ask your insurer directly whether your personal auto policy covers business use. Many personal policies exclude it or limit it, which can leave you exposed after an accident on a work errand.
4. The Contractor's Bond
A licensed contractor must keep a $25,000 contractor's bond on file under Business and Professions Code 7071.6. The contractor license threshold is $1,000, so projects priced at $1,000 or more generally require a license. Confirm with the Contractors State License Board how the threshold applies to a specific job.
A bond is not liability insurance. It exists to protect the public when a licensed contractor fails to meet license obligations. It does not pay your own losses, your injuries, or your defense costs. If a claim is paid on the bond, you are generally required to repay the surety. You still need general liability and workers' compensation coverage as well.
5. Professional Liability
Professional liability requirements depend on your licensing board, so check with your board before you assume anything. Many professions have no mandatory malpractice requirement, while others do.
Attorneys are a common source of confusion. California does not require attorneys to carry malpractice insurance, and the State Bar does not require $1 million in coverage. Instead, Rule of Professional Conduct 1.4.2 requires a lawyer without coverage to tell the client in writing when the matter will likely take more than four hours. A lawyer must also notify clients within 30 days if coverage lapses.
For other licensed professions, look up your board through the Department of Consumer Affairs and read its requirements directly.
Coverage Most Businesses Buy but California Does Not Require
Several important coverages are optional under state law but still matter in practice:
- General liability: California does not require it for most businesses, but landlords, lenders and customers often do. Get it in writing before you sign a lease or a service contract.
- Commercial property: Covers your building, equipment and inventory. Standard commercial property policies typically exclude earthquake damage, so ask a broker about separate earthquake coverage.
- Cyber, employment practices and business interruption: Useful depending on how you handle customer data, how you hire and fire, and how dependent you are on daily revenue.
If you cannot get coverage in the standard market, the California FAIR Plan (property) and the State Compensation Insurance Fund (workers' compensation) act as insurers of last resort. Check your eligibility with each one.
A Practical Checklist
- Register your entity with the Secretary of State through bizfile Online.
- If you will have employees, buy workers' compensation before the first day of work and post the carrier notice.
- Register with the EDD and set up UI, ETT and SDI withholding.
- Confirm your auto limits meet at least $30,000 / $60,000 / $15,000 and check that your policy covers business use.
- If you are licensed, confirm your $25,000 contractor's bond is on file and that your workers' compensation is current.
- Ask your licensing board whether it requires professional liability coverage.
- Check your city and county for a local business tax or registration certificate.
- Ask your landlord, lenders and major customers what coverage they require in writing.
When to Get Professional Help
A licensed insurance broker can tell you what your contracts and your property actually need, and can shop several carriers. An attorney should review any workers' compensation waiver, any unusual contract indemnity clause, and any question about who in your ownership structure must be covered. A CPA should confirm your payroll and franchise tax setup, including the $800 minimum annual franchise tax that applies to LLCs and the LLC fee once California-source income reaches certain levels. For free or low-cost guidance on your business plan and registrations, the California Small Business Development Center network offers advising across the state.
