Who needs workers’ comp in California?
California requires nearly all employers with one or more employees to carry workers’ compensation insurance—even for part-time and seasonal staff. Out-of-state employers with employees working in California must comply with California law. Certain licensed contractors may have additional requirements.
Sole proprietors generally are excluded unless they elect coverage. Eligible corporate officers/directors and certain LLC members/managers may be able to exclude themselves if they meet SB 189 ownership/position tests and file the required waiver with the insurer. Carrier underwriting rules also apply.
Independent contractor status is governed by California’s AB 5 “ABC test” and related exemptions—using a 1099 form does not control status. If a worker is deemed an employee, you may be liable for benefits if uninsured. Prime contractors can face exposure for uninsured subcontractors. Always collect COIs and verify endorsements.
What does California workers’ comp cover?
- Medical care for work-related injuries/illnesses
- Wage replacement during lost time (subject to state limits)
- Temporary and permanent disability benefits
- Supplemental job displacement vouchers (when eligible)
- Death benefits for eligible dependents
Doctor choice in California depends on your setup: an approved MPN allows you to direct care within the network; employees may predesignate a personal physician before injury; without an MPN, employers generally control care for the first 30 days, then the worker may change providers. Network rules and utilization review apply—your adjuster will confirm what’s required.
Unique to California: MPNs and predesignation
With a properly noticed Medical Provider Network (MPN), employers can direct medical care within the network. Employees who validly predesignate a personal physician prior to injury may treat with that doctor from day one. California also requires prompt medical authorization while a claim is pending—carriers must authorize up to a statutory amount for reasonable care until a compensability decision is made.
What does it cost in California?
Premium depends on:
- Payroll by WCIRB classification
- Claims history and loss trends
- Experience Modification (if eligible)
- Credits/debits, safety programs, and carrier filings
Effective rates vary widely by industry and loss profile. California is rated by the WCIRB, which sets classifications and experience rating rules. For accurate pricing, get a quote with current payroll and class details.

California Workers’ Comp FAQs
Is workers’ compensation insurance required in California?
Yes. Most employers with one or more employees must carry workers’ compensation insurance, including for part-time and seasonal staff. Out-of-state employers with employees working in California must comply with California law.
Who can be included or excluded?
Sole proprietors are generally excluded by default but can elect coverage. Eligible corporate officers/directors and certain LLC members/managers may opt out if they meet SB 189 ownership/position tests and file the required waiver with the insurer. Underwriting rules apply—ask us for the correct forms.
Who chooses the doctor?
If you have an approved MPN and provided proper notices, you can direct care within the MPN. An employee who predesignated a personal physician before injury can treat with that doctor. Without an MPN, the employer generally controls medical treatment for the first 30 days; afterward, the worker may change providers.
How are 1099 contractors treated under AB 5?
California uses the AB 5 “ABC test,” which presumes a worker is an employee unless the hiring entity proves all three parts of the test (with some statutory exemptions). Misclassification can create workers’ comp liability. Always collect COIs from subs and verify endorsements.
How much does it cost?
Pricing is driven by WCIRB class codes, payroll, claims history, and your Experience Mod (when eligible), plus carrier credits/debits. We shop multiple A-rated carriers—and SCIF when helpful—to find competitive California rates.
Does California use NCCI and Experience Mods?
California uses the WCIRB for classifications and Experience Mod calculations (not NCCI). Getting the class codes and payroll split right is critical to your premium.
What is the waiting period and TD rate?
California has a 3-day waiting period before temporary disability (TD) wage benefits begin. If disability lasts more than 14 days or includes inpatient hospitalization, TD may be retroactive to day one. TD is generally two-thirds of the employee’s average weekly wage, subject to state minimums and maximums that change annually. Check the DIR for current caps.
What posting and notice requirements apply?
Post the “Notice to Employees—Injuries Caused by Work” in a conspicuous place, give the workers’ comp pamphlet to new hires, provide the DWC-1 claim form within one business day of injury notice, and issue MPN notices if you direct care. Keep carrier/TPA contacts accessible.
What if I’m declined—are assigned risk options available?
Yes. The State Compensation Insurance Fund (SCIF) is California’s market of last resort and often a good option for new ventures or higher-risk classes. We’ll compare SCIF with standard-market quotes.
How do premium audits work?
Most policies are audited annually. Be prepared with payroll reports and quarterly filings, job duty descriptions by class code, overtime details (for crediting where applicable), subcontractor COIs, and owner/officer inclusion or exclusion documents. Missing records can lead to estimated audits and additional premium.
Multi-state employees — how should I set up my policy?
California typically needs to be listed in Item 3.A with a CA-admitted carrier (often via a separate CA policy). We configure multi-state programs so coverage follows your people and satisfies WCIRB rules.
What is a “ghost policy” in California?
A minimal policy used to obtain a COI when there’s little or no payroll. Suitability depends on your contracts and carrier/California rules—some carriers won’t allow owner exclusions without employees. Ask us for compliant options.
Can I get a Waiver of Subrogation or Primary & Noncontributory wording?
Often, yes—subject to carrier approval and job requirements. Request early so we can confirm availability, pricing, and any restrictions (blanket vs. scheduled waiver).
What are the penalties for not carrying coverage?
The state can issue stop-work orders and significant penalties. The Uninsured Employers Benefits Trust Fund (UEBTF) may pay benefits and seek reimbursement from the employer. Don’t risk operating uninsured.
Where can I get official information?
