Group Health Insurance for Small Business in California

A small business in California can offer group health coverage with as few as one eligible employee — and you have more options than the traditional fully-insured plan. Here's how the choices compare and what actually drives the cost.

Short answer: California small employers (generally 1–100 employees) can offer a fully-insured group plan year-round (no minimum-participation lockout during the annual special window), a level-funded plan that can refund unused claims, or skip a group plan entirely and reimburse employees tax-free through an ICHRA. The right fit depends on your headcount, budget, and how much administrative work you want.

Who qualifies

  • Group size — California treats employers with 1 to 100 employees as the small-group market; one common-law W-2 employee (besides the owner/spouse) is generally enough to form a group.
  • Contribution & participation — carriers usually expect the employer to contribute toward premium and a minimum share of eligible employees to enroll, though California's annual open-enrollment window (typically Nov 15–Dec 15) relaxes those rules.
  • ALE line — at 50+ full-time-equivalents you become an Applicable Large Employer and face the ACA employer mandate and 1095-C reporting.

Your main options

  • Fully insured — you pay a fixed premium; the carrier takes the claims risk. Simplest and most predictable; rates are community-rated in CA small group.
  • Level-funded — a fixed monthly amount funds claims plus stop-loss protection; if claims run low, you may get money back. Often a fit for healthier groups of ~10+.
  • ICHRA — instead of a group plan, you reimburse employees tax-free for individual coverage they buy themselves. Budget-controlled and scalable; more on it in the benefits guide and glossary.

What drives the cost

  • Ages & location — CA small-group rates are set by employee age and home ZIP, not health status.
  • Plan design — metal tier (Bronze–Platinum), deductible, network (HMO vs. PPO), and added dental/vision.
  • Employer contribution — how much of premium you cover for employees and dependents.
  • Funding model — level-funded can lower cost for healthy groups but adds variability.

FAQ

How many employees do I need to get group health insurance in California?

Generally one eligible common-law W-2 employee in addition to the owner. California's small-group market covers employers with 1 to 100 employees.

What's the difference between level-funded and fully insured?

Fully insured is a fixed premium with the carrier bearing claims risk. Level-funded is a fixed monthly payment that funds claims plus stop-loss; if claims come in low, the employer can receive a refund — but costs can vary more year to year.

Is an ICHRA a group health plan?

No. An ICHRA reimburses employees tax-free for individual coverage they buy on their own, instead of the employer sponsoring one group plan. It can be a budget-friendly alternative for small businesses.
