The Rule: One Employee Means Coverage
California requires every employer with one or more employees to carry workers compensation insurance. The requirement attaches when the employment relationship starts, not when payroll is first run — someone working their first training shift is already an employee. Part-time status doesn’t matter. Family members on payroll generally count. Paying in cash doesn’t change anything except how much harder the audit conversation gets.
What doesn’t trigger the requirement: a business with no employees at all. A sole proprietor working alone, or partners with no staff, aren’t required to cover themselves — they’re outside the system by default and can opt in for their own coverage if they want it. The requirement begins when the first person who isn’t an owner starts working for you. And be careful with the “they’re a contractor, not an employee” assumption — California applies a strict test, and misclassifying your first hire as a 1099 contractor is one of the most expensive shortcuts a new employer can take. Our 1099 vs employee guide covers where that line actually sits.
What Operating Without Coverage Costs
Skipping coverage isn’t a paperwork violation — it’s one of the more heavily enforced obligations in California employment law. An uninsured employer faces stop orders that shut the business down until coverage is in place, fines, potential misdemeanor exposure, and — the part that actually ends businesses — personal liability for the full cost of any workplace injury, uncapped. If an uninsured worker is hurt, the state’s Uninsured Employers Benefits Trust Fund can pay the injured worker and then pursue the employer for reimbursement. Penalty amounts and enforcement mechanics change over time; the current figures are less important than the structure, which is uniformly bad for the employer. The full picture is in our penalties guide.
For licensed contractors there’s an additional layer: workers comp status is tied to your contractor license, and letting coverage lapse with employees on the books puts the license itself at risk.
What Your First Policy Will Cost
Premium is payroll-driven: the rate for your class code per $100 of payroll, times your payroll. With one employee the payroll is small, so the premium is usually modest — but the rate difference between occupations is enormous:
| First hire | Class code | Rate | Payroll | Approx. base premium |
|---|---|---|---|---|
| Office admin | 8810 — Clerical | $0.15/100 | $45,000 | ~$68* |
| Retail associate | 8017 — Retail store | $2.02/100 | $36,000 | ~$727* |
| Restaurant worker | 9079 — Restaurant | $3.42/100 | $32,000 | ~$1,094 |
| Janitorial worker | 9015 — Janitorial | $4.22/100 | $34,000 | ~$1,435 |
| Carpenter | 5403 — Carpentry | $8.14/100 | $50,000 | ~$4,070 |
*One thing every first-time buyer should expect: minimum premiums. Carriers set a floor on what any policy costs regardless of how small the payroll is, so the tiny arithmetic results in the table’s first rows get lifted to the carrier’s minimum. The exact floor varies by carrier and class; for very small clerical and retail risks it’s common for the minimum — not the rate math — to set the price. New businesses also start life without an experience mod, which is neutral: no claims history means no credit and no debit until you’ve been in the system long enough to qualify for one.

What a Quote Actually Requires
First-policy applications are short. A broker can typically quote with:
- What the employee will do — this drives the class code, which drives everything else. Describe duties honestly; the code is assigned by actual work performed, not job title.
- Estimated annual payroll — a good-faith estimate is fine. The policy trues up at the annual audit, so estimate realistically rather than lowballing: underestimating just converts into a surprise bill later.
- Your FEIN and entity details — legal name, entity type, address.
- Start date — coverage should be effective on or before the first day of work, and binding a standard first policy usually takes days, not weeks. Don’t schedule the hire first and shop coverage second.
- Owner status decisions — whether owners are excluded or included, which changes the premium base. See the exclusion guide.
New ventures without claims history sometimes find the open market thin for tougher class codes — that’s what the state fund is for, and it’s a normal starting point rather than a failure. Our state fund vs open market guide explains how businesses start there and graduate out.
After You Bind: The Obligations That Come With the Policy
Buying the policy is most of the job, but not all of it. California employers also take on a set of workplace obligations: posting the required workers comp notice where employees can see it, giving new hires the required coverage information at hire, providing a claim form promptly when an injury is reported, and maintaining an Injury & Illness Prevention Program — which is required of California employers generally, not just large ones. None of these are burdensome for a small shop, but they’re checked when something goes wrong, and the first 24 hours after an injury go far better when the paperwork was in place beforehand.
Two habits worth building from day one: report payroll accurately as you grow (adding employee #2 and #3 mid-term is a simple policy change, not a new application), and keep certificates and class-code assignments current at each renewal. Growth is exactly when pay-as-you-go billing starts to make sense — premium tracks actual payroll instead of a stale annual estimate.
The Mistakes First-Time Employers Make
- Calling the hire a contractor to skip coverage. The test is about control and the nature of the work, not what the parties agree to call it. Misclassification gets unwound at audit or — far worse — after an injury.
- Waiting until after the start date. Coverage isn’t retroactive. An injury on day one with no policy in force is the full uninsured-employer scenario.
- Lowballing the payroll estimate. The audit trues it up anyway; the underestimate just becomes debt.
- Wrong class code. Assigning your field employee a clerical code saves money right up until the audit reclassifies them retroactively.
- Forgetting the policy exists. Renewals, audits, and mod eligibility all arrive on schedule. A broker who works your renewal is the difference between a policy that quietly gets expensive and one that stays priced correctly.
