Is Health Insurance Required in California?

Key Takeaways

Health insurance is required in California under a state individual mandate active since January 1, 2020.

The 2026 California penalty is $950 per uninsured adult or 2.5% of household income, whichever is higher.

Each uninsured dependent child under 18 adds $450 to the penalty, while a family of four owes at least $2,800.

Exemptions are available for unaffordability, coverage gaps under three consecutive months and qualifying hardships.

Does California Require Health Insurance?

California requires every resident to have minimum essential coverage for each month of the year or pay a penalty to the California Franchise Tax Board. The state individual mandate took effect January 1, 2020, after the federal individual mandate penalty dropped to zero in 2019. California's requirement operates independently of federal law as the federal mandate carries no financial penalty in 2026, so California residents can't rely on that to avoid state-level consequences. Everyone who files a California state income tax return must report their coverage status.

California's mandate covers the enrollee's spouse or domestic partner and all dependents claimed on the California return. And coverage must be active for each calendar month as eligibility without enrollment doesn't satisfy the requirement. Most health insurance options from employers, Covered California or direct-purchase sources satisfy California's minimum essential coverage standard as long as the plan is ACA-compliant.

What Is the California Health Insurance Penalty in 2026?

The California Franchise Tax Board calculates the penalty using two methods and charges whichever produces the higher amount. The flat method applies $950 per uninsured adult and $450 per uninsured dependent child under 18 for 2026. The income-based method applies 2.5% of household gross income above the state filing threshold. For a single adult earning $80,000, the income-based calculation would exceed the flat penalty and determine the actual amount owed.

Who Is Uninsured	Annual Flat Penalty	Income-Based Penalty (2.5% rule)
Single adult (full year)	$950	2.5% of gross income above filing threshold
Dependent child under 18 (full year)	$450	Half the adult flat-rate method (2.5% prorated)
Two adults, two children under 18 (full year)	At least $2,800	2.5% of total household income above threshold
Single adult (three months uninsured)	$238 (25% of $950)	25% of full-year income-based amount

The California penalty accrues month by month, not as a single annual charge. A resident uninsured for six months owes half the annual flat penalty when the flat method produces the higher amount. The Franchise Tax Board fine is only part of the financial exposure. Going without health insurance leaves a resident fully responsible for the $10,600 individual out-of-pocket maximum that ACA plans cap for in-network services.

What Counts as Qualifying Coverage Under California's Mandate?

California uses the federal definition of minimum essential coverage (MEC) to determine which plans satisfy the mandate. Employer-sponsored group plans, plans purchased through the health insurance Marketplace, Medicare Parts A and C, and Medi-Cal all qualify. But coverage must be active for each month as being eligible for but not enrolled in a plan leaves the resident subject to the California Franchise Tax Board penalty. Short-term health plans, dental-only plans and vision-only plans don't meet the MEC standard.

Employer-Sponsored Coverage:

Employer group health plans satisfy the California mandate for enrolled employees and their enrolled dependents. Eligibility alone doesn't count. Employees whose employer offers coverage but who haven't enrolled are subject to the Franchise Tax Board penalty for each month without active coverage.

Covered California Marketplace Plans:

ACA-compliant plans purchased through Covered California or directly from a participating insurer satisfy the state mandate. California residents with household incomes between 100% and 400% of the federal poverty level qualify for a premium tax credit that reduces their monthly Covered California payment, sometimes to under $50 per month.

Silver-tier plan enrollees who qualify for cost-sharing reductions can cut their annual deductible below the standard Silver-tier level. That's one reason premiums and real-world costs among California health insurance plans differ more than the metal tier alone suggests.

Medi-Cal (California Medicaid):

Most Medi-Cal coverage satisfies California's minimum essential coverage standard. California expanded Medi-Cal to adults with household incomes up to 138% of the federal poverty level.

Medi-Cal enrollment is open year-round with no annual open enrollment window. Residents may apply through coveredca.com or their county social services office.

Medicare Parts A and C:

Original Medicare (Part A) and Medicare Advantage (Part C) both satisfy the California mandate for enrolled residents. Medicare Part B alone doesn't qualify. California residents enrolled in a qualifying Medicare plan don't owe the Franchise Tax Board penalty for covered months.

Plans That Don't Qualify:

Short-term health plans, fixed-indemnity products, health care sharing ministry memberships and dental- or vision-only plans don't meet California's minimum essential coverage standard. Enrollees in these plans who lack qualifying coverage elsewhere owe the California Franchise Tax Board penalty for each non-compliant month.

This MEC standard applies specifically to California's state individual mandate. Coverage requirements for other purposes, such as employer reporting obligations or subsidy eligibility, may differ.

Who Is Exempt from California's Health Insurance Requirement?

Not every uninsured California resident owes the penalty. The California Franchise Tax Board recognizes exemptions claimed on Form 3853 when filing a state income tax return. Some exemptions are applied automatically based on information already on the return; others require documentation submitted through Covered California before the end of the plan year. Qualifying for an exemption eliminates the penalty for each month the exemption applies, including months where coverage was unavailable or unaffordable.

Unaffordability of Coverage:

Residents for whom the lowest-cost Bronze plan or an employer plan costs more than a defined share of household income may qualify for an unaffordability exemption on Form 3853. The California Franchise Tax Board's penalty estimator at ftb.ca.gov calculates whether premiums meet the threshold. Residents near the borderline often pay less per month for affordable health insurance than the prorated penalty they would otherwise owe.

Short Coverage Gap:

A single continuous gap in coverage of fewer than three consecutive months qualifies for an automatic exemption. Residents who experience a brief lapse between jobs or during a transition period can claim this exemption without additional documentation.

The exemption applies only once per tax year; multiple gaps don't each qualify separately.

Qualifying Hardship Circumstances:

Homelessness, recent eviction or foreclosure, bankruptcy, domestic violence, illness or death of a close family member and other qualifying circumstances each support a separate hardship exemption. Covered California grants hardship exemptions when those circumstances made keeping coverage unreasonably difficult. Apply for a Covered California exemption before year-end when possible. Some hardship exemptions require prior approval.

Membership in Exempt Groups:

Members of federally recognized Indian tribes, people not lawfully present in the United States, incarcerated individuals and members of certain qualifying religious groups are exempt from California's mandate. Residents in these categories claim the applicable exemption on Form 3853 at state income tax filing.

SHORT-TERM PLANS DO NOT SATISFY CALIFORNIA'S MANDATE

Short-term health insurance is not minimum essential coverage under California's individual mandate. Residents enrolled in a short-term plan and no other qualifying coverage owe the California Franchise Tax Board penalty for each month the short-term plan was their only coverage. Confirming which types of health insurance satisfy the mandate is the first step before purchasing any non-Marketplace product.

How to Get Health Insurance in California Before the Penalty Applies

California residents have four main paths to getting health insurance: Medi-Cal, Covered California, an employer plan or a direct-purchase ACA-compliant plan. The right option depends on income, employment status and household size. Coverage gaps count month by month on the Franchise Tax Board return, so confirming enrollment before year-end is the only way to avoid a partial-year penalty.

1
Check Whether You Qualify for Medi-Cal First
Adults with household incomes up to 138% of the federal poverty level qualify for Medi-Cal at no cost. Medi-Cal enrollment is open year-round, so there's no missed-window risk. Apply at coveredca.com or through your county social services office. Most applications are processed within 45 days.
2
Estimate Your Premium Tax Credit Before Choosing a Plan
California residents with household incomes between 100% and 400% of the federal poverty level qualify for a federal premium tax credit that lowers the monthly cost of a Covered California plan. In 2026, many income-eligible enrollees pay well under $100 per month after the credit. The average cost of health insurance for a 40-year-old in California on a Silver plan without subsidies is between $586 to $822 per month and the premium tax credit reduces that figure further for most income-eligible households.
3
Enroll Through Covered California During Open Enrollment
Covered California's annual open enrollment period runs November 1 through January 31. Plans purchased during open enrollment take effect January 1 if enrolled by December 15, or February 1 for enrollments between December 16 and January 31. Outside open enrollment, a qualifying life event is required to trigger a special enrollment period.
4
Enroll in Your Employer Plan if One Is Offered
Enrolling in an employer group health plan during your company's open enrollment period satisfies California's mandate. Confirm the plan meets the ACA minimum value standard, which requires it to cover at least 60% of expected in-network costs. Employees who miss their employer's enrollment window may still qualify for health insurance after open enrollment through a qualifying life event or Medi-Cal.

Bottom Line

California's state mandate has carried a real financial penalty since 2020. A resident uninsured for the full year owes at least $950 and a higher-income household can owe several thousand dollars. For most California residents, keeping coverage costs less annually than the Franchise Tax Board fine, particularly after subsidies reduce Marketplace premiums.

California's Health Insurance Requirement: FAQ

We've answered the most common questions about the penalty calculation, exemptions, coverage options and how California's mandate differs from federal law:

Does California's health insurance mandate work the same as the federal individual mandate?

California's state mandate is separate from the federal health insurance mandate and carries its own financial penalty, while the federal penalty has been set to zero since 2019. California, Massachusetts, New Jersey, Rhode Island, Vermont and Washington, D.C. are the only jurisdictions that enforce active state-level requirements with financial consequences in 2026.

Can I avoid the California penalty if I couldn't afford health insurance this year?

California residents qualify for an unaffordability exemption on Form 3853 when the lowest-cost Bronze Marketplace plan or an available employer plan costs more than the household income threshold, as calculated by the California Franchise Tax Board's estimator at ftb.ca.gov. Low-income residents who qualify for Medi-Cal are exempt because Medi-Cal enrollment is open year-round at no cost.

What if I had health insurance for only part of the year?

The California penalty is prorated by month, so a resident uninsured for three months owes 25% of the annual flat penalty, not the full-year amount. A single continuous gap of fewer than three consecutive months qualifies for an automatic short coverage gap exemption claimed on Form 3853. Multiple separate gaps in the same tax year don't each qualify independently.

Does the California mandate apply to children on a parent's employer plan?

Dependent children enrolled on a parent's employer group plan are covered under the parent's minimum essential coverage for each enrolled month. Children eligible for a parent's plan but not actually enrolled remain subject to the California Franchise Tax Board penalty unless another qualifying coverage source covers them.

What happens if I don't file Form 3853 but I'm actually exempt?

Failing to file Form 3853 when an exemption applies means the California Franchise Tax Board calculates the penalty based on the coverage information reported on the state return. Filing Form 3853 with the correct exemption code is the only way to formally claim the exemption and eliminate the penalty.

Are there low-cost coverage options in California that satisfy the mandate?

Medi-Cal covers California residents with household incomes up to 138% of the federal poverty level at no cost and satisfies the state mandate for each enrolled month. Residents above that threshold can find affordable Covered California plans at well under $100 per month after a premium tax credit, with some Bronze-tier options at $0 for lower-income households.
