California employers face health insurance requirements at both the federal and state level. The federal Affordable Care Act (ACA) requires employers with 50 or more full-time equivalent employees to offer affordable health coverage or face significant penalties. California adds its own individual mandate, requiring residents to maintain coverage or pay a state tax penalty.
This guide explains what California employers are required to provide, the 2026 penalty amounts, and how to set up a benefits program that keeps you compliant and helps you attract and retain employees.
Key Takeaways
- The ACA employer mandate applies to businesses with 50 or more full-time equivalent employees. These “applicable large employers” (ALEs) must offer affordable, minimum-value health coverage.
- 2026 penalties: $3,340 per full-time employee (minus 30) if you fail to offer coverage, or $5,010 per subsidized employee if your coverage is unaffordable or below minimum value.
- California has its own individual mandate requiring residents to have health insurance or pay a state penalty on their tax return.
- Employers with fewer than 50 FTEs are not required to offer health insurance, but many do to compete for talent.
- Small employers (1-50 employees) may qualify for SHOP marketplace plans or the Small Business Health Care Tax Credit.

The ACA Employer Mandate
The Affordable Care Act’s employer shared responsibility provision, often called the “employer mandate” or “pay or play” rule, requires applicable large employers (ALEs) to offer minimum essential coverage to at least 95% of their full-time employees (and their dependents up to age 26).
An ALE is any employer that averaged 50 or more full-time equivalent employees during the prior calendar year. Full-time means an average of 30 or more hours per week.
If you are an ALE, the coverage you offer must meet two standards:
- Minimum value: The plan must cover at least 60% of the total allowed cost of benefits. Most standard group health plans meet this threshold.
- Affordability: The employee’s required contribution for self-only coverage cannot exceed a percentage of their household income (see the affordability section below).
If your coverage fails either test and a full-time employee receives a premium tax credit through Covered California, you owe a penalty.
2026 Penalty Amounts
The IRS adjusts ACA penalty amounts annually for inflation. For plan years beginning in 2026, the penalties are (per IRS Revenue Procedure 2025-26):
| Penalty | Trigger | 2026 Amount | How It Is Calculated |
|---|---|---|---|
| Penalty A (4980H(a)) | Failure to offer minimum essential coverage to at least 95% of full-time employees, and at least one FTE receives a Covered California subsidy | $3,340 per year ($278.33/month) | Number of full-time employees minus 30, multiplied by $3,340 |
| Penalty B (4980H(b)) | Coverage offered does not meet minimum value or affordability standards, and a full-time employee receives a Covered California subsidy | $5,010 per year ($417.50/month) | Number of FTEs who receive subsidized coverage, multiplied by $5,010 |
What these numbers mean in practice
Consider a California employer with 200 full-time employees.
- Penalty A scenario: The employer offers no health coverage, and one or more employees get subsidized Covered California plans. Penalty: (200 – 30) x $3,340 = $567,800 for the year.
- Penalty B scenario: The employer offers coverage that is technically unaffordable, and 10 employees receive Covered California subsidies. Penalty: 10 x $5,010 = $50,100 for the year.
These penalties are not tax-deductible, making them even more expensive on an after-tax basis.
How to Determine If You Are an ALE
Count all employees who averaged 30 or more hours per week during the prior calendar year. Then add the hours of part-time employees and divide by 120 (or 130 for monthly measurement) to get a full-time equivalent count.
| Employee Type | How They Count |
|---|---|
| Full-time (30+ hours/week) | Each counts as 1 FTE |
| Part-time (under 30 hours/week) | Total monthly hours / 120 = FTEs |
| Seasonal workers | Counted unless they worked fewer than 120 days and adding them pushes you over 50 |
| Common ownership / controlled groups | Employees across all commonly owned entities are aggregated |
Affordability Requirements
Even if you offer health insurance, it must be “affordable” under the ACA. The employee’s required contribution for the lowest-cost self-only plan cannot exceed a set percentage of their income.
Because employers don’t always know each employee’s household income, the IRS provides three safe harbors you can use to demonstrate affordability:
- W-2 safe harbor: The employee’s contribution does not exceed the affordability percentage of their W-2 Box 1 wages.
- Rate of pay safe harbor: The contribution does not exceed the affordability percentage of their hourly rate x 130 hours per month.
- Federal poverty line safe harbor: The contribution does not exceed the affordability percentage of the federal poverty line for a single individual.
You only need to satisfy one safe harbor. The federal poverty line safe harbor is the simplest because it uses a single, published number rather than individual employee data.
California Individual Mandate
In addition to the federal employer mandate, California has its own individual mandate (SB 78, effective January 2020). This requires California residents to maintain qualifying health coverage for themselves and their dependents, or pay a state tax penalty.
The state penalty is the greater of a flat dollar amount per adult and child, or a percentage of household income. For most working adults, the penalty is several hundred dollars per year.
As an employer, the individual mandate reinforces the value of offering group coverage. Employees who do not have coverage through work must buy it on their own through Covered California or face the state penalty. Offering group health insurance removes that burden and makes your company more attractive to job seekers.
Options for Small Employers
If you have fewer than 50 FTEs, you are not required to offer health insurance under the ACA. But many California small employers choose to offer it because it helps with hiring, retention, and employee satisfaction.
Group health plans
Small group plans (2-50 employees in California) are available through insurance carriers and the Covered California for Small Business (SHOP) marketplace. Carriers cannot deny coverage or charge more based on employees’ health conditions in the small group market.
Small Business Health Care Tax Credit
Employers with fewer than 25 FTEs and average annual wages below a set threshold may qualify for a federal tax credit of up to 50% of the employer’s premium contribution. The credit is available for two consecutive years and requires purchasing coverage through SHOP.
Health Reimbursement Arrangements (HRAs)
Small employers that don’t want to manage a traditional group plan can offer an Individual Coverage HRA (ICHRA) or a Qualified Small Employer HRA (QSEHRA). These arrangements let you reimburse employees tax-free for individual health insurance premiums and, in some cases, medical expenses. Employees buy their own coverage, and you contribute a defined amount.
Setting Up a Group Health Plan
If you decide to offer group health insurance, here’s the process.
1. Determine your contribution strategy
Decide how much of the premium you will pay and how much employees will contribute. Most California employers cover at least 50% of the employee-only premium. Some cover a percentage of dependent coverage as well.
2. Choose a plan structure
Common options include HMO, PPO, EPO, and high-deductible health plans with HSA. HMOs are popular in California because of strong provider networks and lower premiums. PPOs offer more flexibility but cost more. Many employers offer a choice of two or three plans so employees can pick the one that fits their needs and budget.
3. Work with a broker
An independent benefits broker compares plans and premiums across multiple carriers, handles the application and enrollment process, and serves as your ongoing resource for compliance questions, plan changes, and renewals. Broker services are typically paid by the carrier through commissions, so there is no direct cost to you.
4. Manage enrollment and compliance
New employees must be offered coverage within their eligibility period (typically 60 to 90 days from hire). You must provide Summary of Benefits and Coverage (SBC) documents, maintain records for ACA reporting (Forms 1094-C and 1095-C for ALEs), and notify employees about their marketplace rights.
Frequently Asked Questions
Do California employers have to offer health insurance?
Only if you have 50 or more full-time equivalent employees. The ACA employer mandate requires ALEs to offer affordable, minimum-value coverage. Employers with fewer than 50 FTEs are not required to offer coverage but may choose to do so.
What is the penalty for not offering health insurance in California in 2026?
For ALEs that fail to offer minimum essential coverage, the Penalty A amount is $3,340 per full-time employee (minus 30) per year. If coverage is offered but is unaffordable or below minimum value, Penalty B is $5,010 per subsidized employee per year. These amounts are not tax-deductible.
Do I have to cover part-time employees?
The ACA mandate applies only to full-time employees (30+ hours per week). You are not required to offer health coverage to part-time workers. However, part-time hours count toward your FTE calculation for determining ALE status.
Can I offer different plans to different employee groups?
Yes, as long as the distinction is based on legitimate job classifications (salaried vs. hourly, different locations, different job categories) and not designed to discriminate. The plans offered to each group must still meet minimum value and affordability standards for full-time employees in that group.
What is the California individual mandate penalty?
California residents who do not maintain qualifying health coverage pay a penalty on their state tax return. The penalty is the greater of a flat dollar amount per person or a percentage of household income. This applies to employees who decline your coverage and do not have coverage elsewhere.
Is there a tax credit for small employers who offer health insurance?
Yes. The Small Business Health Care Tax Credit is available to employers with fewer than 25 FTEs and average annual wages below the threshold. The credit can be up to 50% of the employer’s premium contribution for up to two years, but you must purchase coverage through the SHOP marketplace to qualify.
