Health Insurance Requirements for Small Businesses

As a California business owner, you need to know if you’re required to offer health insurance to your employees under the Affordable Care Act and when a penalty could apply.

The information below is for informational purposes only and is based on the IRS Employer Shared Responsibility provisions in section 4980H of the Internal Revenue Code. Visit the IRS website or contact a tax professional for more information.

Am I required to offer health insurance?

Under the Affordable Care Act, you are treated as an applicable large employer if, on average, during the previous calendar year, you had:

  • At least 50 full-time employees, or

  • A combination of full-time and part-time employees that equals 50 or more full-time equivalent employees.

If you are an applicable large employer:

  • You must offer health insurance that is affordable and provides minimum value to your full-time employees and their dependents, or

  • You may owe a penalty payment (also known as the employer shared responsibility or “employer mandate” penalty) to the IRS.

All types of employers — including tax‑exempt organizations and government entities — can be applicable large employers.

Businesses With Under 50 Employees

If you have fewer than 50 full‑time employees, including full-time equivalent employees, you’re not subject to the employer shared responsibility provisions or penalty payments to the penalty or the related IRS reporting requirements. Most businesses fall below this threshold.

Even though you’re not required to offer insurance, you can still:

  • Provide Affordable Care Act‑compliant health benefits to your employees through Covered California for Small Business, which serves employers with 100 or fewer full-time equivalent employees; and

  • Use IRS resources specifically designed for small employers to understand your options and any available tax provisions.

Who counts as a full-time employee?

You’ll need to calculate your exact number of employees to find out if you’re required to offer them health insurance.

Full-Time Employees and Full-Time Equivalent Employees

For employer-mandate purposes:

  • A full-time employee is someone you employ on average at least 30 hours per week.

  • To determine whether you are an applicable large employer, you must count both:

    • Your full-time employees, and

    • Your full-time equivalent employees, which are calculated from the hours of your part‑time employees.

You must total each employee’s hours of service to determine your number of full‑time employees and full-time equivalent employees. The IRS Employer Shared Responsibility page includes examples that walk through these calculations.

Use the Employer Shared Responsibility Provision Estimator to estimate how many full-time equivalent employees you have and whether you may be an applicable large employer.

Seasonal Workers and Seasonal Employees

The Affordable Care Act uses two similar but distinct terms:

  • Seasonal worker: Relevant when you are determining whether you are an applicable large employer. Seasonal workers perform labor or services on a seasonal basis (as defined by the U.S. Department of Labor), such as retail staff hired exclusively for the holiday season. You may apply a reasonable, good‑faith interpretation of this term.

  • Seasonal employee: Relevant when you use the look‑back measurement method to determine if a particular worker is treated as full time.

You should apply these definitions carefully when you calculate your number of full-time equivalent employees and decide whether you are an applicable large employer.

Do I owe a penalty for not offering health insurance?

If you are an applicable large employer, you can either:

  • Offer affordable health insurance that provides minimum value to your full‑time employees and their dependents, or

  • Potentially owe a penalty (employer shared responsibility payment) to the IRS.

You may owe one of two possible penalty payments (but never both at the same time). In general, you could owe a penalty if:

  1. You offer health insurance to all or at least 95 percent of your full‑time employees, but at least one full‑time employee receives financial help (a premium tax credit) to help pay for their insurance through a health insurance marketplace like Covered California — for example, because that employee was not actually offered insurance, or your offer was not affordable or didn’t provide minimum value; or

  2. You don’t offer health insurance, or you offer insurance to fewer than 95 percent of your full‑time employees and their dependents, and at least one full‑time employee receives financial help (a premium tax credit) through a marketplace like Covered California.

You don’t automatically owe a penalty payment just because some or all of your employees buy insurance through Covered California or have Medicare or Medi‑Cal. You only become liable if at least one full‑time employee receives a premium tax credit (financial help) for health insurance through a marketplace like Covered California.

In general, a full‑time employee isn’t eligible for financial help (a premium tax credit) through Covered California if you offer that employee health insurance that is affordable and provides minimum value, even if the employee chooses to decline your offer and enrolls in health insurance through Covered California, Medicare or Medi‑Cal instead.

Dependents, Spouses and What You Must Offer

Who Counts as a Dependent

For employer shared responsibility purposes, a dependent is your employee’s child under age 26, including a child who has been legally adopted or placed for adoption.

Spouses are not considered dependents, and neither are stepchildren or foster children.

What You’re Required to Offer

As an applicable large employer, you must:

  • Offer health insurance that is affordable and provides minimum value to your full‑time employees, and

  • Offer health insurance to their dependents (as defined above).

However, the Affordable Care Act does not require you to pay for dependents’ premiums. Only the offer of dependent coverage is mandated. You may be subject to a penalty if you fail to offer health insurance and a full‑time employee receives a tax subsidy through a health insurance marketplace like Covered California.

How Spouses Affect Penalty Payments

Because a spouse is not a dependent for these rules:

  • You’re not subject to a penalty payment solely because you don’t offer insurance to spouses or because spouses purchase insurance through Covered California or enroll in Medicare or Medi‑Cal.

  • You’re only liable for a penalty payment if at least one full‑time employee (not a spouse) receives a premium tax credit.

If you offer health insurance that is affordable and provides minimum value to a full‑time employee’s spouse, that spouse will not be eligible for a premium tax credit.
