Key Takeaways

The California health insurance penalty applies to every resident who files a state return and lacks qualifying coverage in 2026.

The Franchise Tax Board charges $950 per adult or 2.5% of gross income in 2026, whichever is higher.

Covered California plans, employer coverage, Medi-Cal and Tricare qualify. Short-term plans and Medicare Part B alone do not count.

California offers exemptions for affordability hardship, short coverage gaps and other qualifying circumstances, claimed on Form 3853.

What Is the California Health Insurance Penalty?

The California health insurance penalty is $950 per adult or 2.5% of gross income, whichever is higher. The Franchise Tax Board charges it when a resident files their state return without qualifying coverage for any month in 2026.

California reinstated its individual health insurance mandate on January 1, 2020, and the Franchise Tax Board enforces it through the state tax return. The California requirement is separate from the federal individual mandate, which has carried no penalty since 2019. California residents who go uninsured for any month in 2026 owe a penalty calculated on their state return. Residents comparing coverage options can find health insurance options in California.

A resident owes the full $950 per adult only when uninsured for all 12 months with no qualifying exemption. A single adult uninsured for two months pays $158, two months at the $79 monthly rate. A family of four uninsured for those same two months pays $475.

Who Has to Pay the California Health Insurance Penalty?

Every California resident required to file a state tax return must keep minimum essential coverage for each calendar month or owe the Franchise Tax Board penalty. The requirement covers the filer, their spouse and all dependents listed on the state return. Residents whose income falls below the state filing threshold owe no penalty. See how California's requirement differs from the other states.


California resident who files a state return with qualifying coverage active for all 12 months.	No penalty applies. The Franchise Tax Board treats full-year coverage as full compliance regardless of plan type, as long as it meets minimum essential coverage standards.
California resident who files a state return and was uninsured for one or more months in 2026.	Penalty is owed for each uninsured month. The Franchise Tax Board prorates the annual amount by dividing by 12 and multiplying by the number of uninsured months.
Dependent child listed on a California return with qualifying coverage for every month of the year.	No penalty applies for that dependent. Coverage must be active for each calendar month claimed, not just at year-end.
Dependent child listed on a California return with no qualifying coverage for one or more months.	$475 is added to the household penalty for each uninsured dependent child per year. A family of four without coverage owes at least $2,850 annually.
Resident with household income below California's state filing threshold for 2026.	Automatically exempt. Residents below the filing threshold owe no penalty and don't need to file Form 3853 solely for that reason.
Resident enrolled only in a short-term health plan or a non-ACA-compliant product for any month in 2026.	Short-term plans don't meet California's minimum essential coverage definition. The full prorated penalty applies for every month the resident held only a non-qualifying product.
Resident with Medicare Part B only, without Medicare Part A or a Medicare Advantage plan.	Medicare Part B alone doesn't satisfy the mandate. The penalty applies for each month the enrollee lacked Part A or a Medicare Advantage plan.
Resident with an approved Form 3853 exemption covering specific uninsured months.	Penalty is waived for the exact months the exemption covers. Months not covered by the approved exemption remain subject to the prorated penalty.
Resident not required to file a California state tax return for 2026.	No penalty obligation exists without a filing requirement. Residents in this situation don't need to report coverage or file Form 3853.

MONEYGEEK EXPERT TIP

The month-by-month calculation matters more than most people expect. A resident who had coverage for nine months and lacked it for three owes $237, three months at the $79 monthly rate. MoneyGeek recommends calculating your exact uninsured months before filing Form 3853 to avoid overpaying. Current thresholds are at ftb.ca.gov.

What Coverage Counts to Avoid the California Penalty?

Minimum essential coverage (MEC) is any qualifying health plan that satisfies California's individual mandate. Qualifying types include employer group plans, Covered California Marketplace plans and government programs such as Medi-Cal and Tricare. Not every health product on the market meets the standard.


Employer-sponsored group health plans	✓ Qualifies. Any ACA-compliant group plan an employer offers qualifies, regardless of the insurer's home state.
Covered California Marketplace plans (Bronze, Silver, Gold, Platinum)	✓ Qualifies. All four tiers purchased through Covered California or a participating insurer such as Kaiser Permanente or Anthem Blue Cross qualify.
Medicare Part A (hospital insurance)	✓ Qualifies. Medicare Part A satisfies the mandate on its own. Enrollees who also have Medicare Advantage (Part C) are covered by that plan instead.
Medicare Advantage (Part C)	✓ Qualifies. Any Medicare Advantage plan satisfies the mandate for every month it's active.
Medi-Cal and CHIP	✓ Qualifies. Both programs satisfy the mandate for every enrolled member, with no premium requirement for eligible households.
COBRA continuation coverage	✓ Qualifies while premiums are paid and the plan stays active. A lapsed COBRA creates a gap subject to the penalty.
Tricare	✓ Qualifies for active-duty service members, veterans and eligible dependents.
Student health plans (ACA-compliant only)	✓ Qualifies if the university-issued plan meets ACA standards. Non-ACA-compliant student plans don't qualify.
Federal Employee Health Benefits (FEHB) plans	✓ Qualifies for enrolled federal employees and their enrolled dependents.
Short-term health plans	✗ Does not qualify. These plans aren't ACA-compliant and don't cover pre-existing conditions or essential health benefits.
Limited-benefit, fixed indemnity or accident-only plans	✗ Does not qualify. These pay a fixed dollar amount per event and don't meet the MEC definition.
Medicare Part B alone	✗ Does not qualify. Part B without Part A or Medicare Advantage doesn't satisfy the mandate.
Health care sharing ministry memberships	✗ Does not qualify. These aren't insurance and aren't recognized as MEC by the Franchise Tax Board.
Standalone dental or vision plans	✗ Does not qualify. These cover specific services only and don't count as minimum essential coverage.
Critical illness or hospital indemnity policies	✗ Does not qualify. These supplement but don't replace primary ACA-compliant coverage.

Coverage types reflect California's minimum essential coverage standards per the Franchise Tax Board. Short-term and non-ACA-compliant plans don't satisfy California's mandate. Verify current MEC definitions at ftb.ca.gov.

How Do You Avoid the California Health Insurance Penalty?

California's individual mandate has required residents to maintain qualifying health coverage every month since 2020. The Franchise Tax Board enforces it each year through your state tax return, calculating the penalty for each month without coverage or an approved exemption. Acting before a coverage gap starts is the only way to avoid it. Retroactive enrollment doesn't satisfy the mandate for months already passed.

1
Enroll Through Covered California Before December 31
Covered California's open enrollment opens November 1 and closes January 31. A plan selected by December 31 takes effect January 1 with no coverage gap for the new year.
2
Join Your Employer Health Plan During Open Enrollment
Employer group health plans qualify as minimum essential coverage under California's mandate regardless of the insurer, as long as the plan is ACA-compliant. Most employer open enrollment windows open in October or November for January 1 coverage. Employees who decline employer coverage without enrolling in an alternative qualifying plan remain subject to the Franchise Tax Board penalty for each month without coverage.
3
Apply for Medi-Cal if Your Income Is Eligible
Medi-Cal, California's Medicaid program, covers residents with household incomes up to 138% of the federal poverty level at no premium cost. Unlike Covered California's annual enrollment window, Medi-Cal enrollment stays open year-round. Applications are accepted through Covered California, the county social services office or BenefitsCal.gov. Coverage can start as early as the month of approval for qualifying households.
4
Use a Special Enrollment Period After a Life Event
Losing job-based coverage, getting married or having a child all open a 60-day special enrollment period through Covered California. Moving to a new coverage area within California, such as a different county where different plans are available, also triggers this window. Qualifying life events that open this window also include adoption, a change in immigration status and release from incarceration, per Covered California.
5
File for an Exemption on Your State Tax Return
California residents who qualify for a health insurance exemption owe no penalty for the months the exemption covers. Exemptions are claimed on California Form 3853 filed with the state return, or approved in advance through the Covered California website. The Franchise Tax Board adjusts the penalty calculation retroactively to apply approved exemptions to the specific months they cover.
6
Report Your Coverage Status on California Form 3853
Every California tax filer reports their health coverage status for the year on Form 3853, filed with the state return. Filers who had qualifying coverage for all 12 months check the full-year coverage box and owe no penalty. Those who were uninsured for any month report those months on Form 3853, apply any exemptions and calculate any remaining penalty on the same form before submitting to the Franchise Tax Board. Retroactive enrollment doesn't satisfy the mandate for months already passed.

MISSED COVERED CALIFORNIA OPEN ENROLLMENT?

Covered California's enrollment window closes January 31. After that date, you can't enroll until November unless a qualifying life event opens a special enrollment period. COBRA, employer coverage and Medi-Cal (year-round for income-eligible residents) are the main options. A full overview of alternatives is at COBRA alternatives.

What Exemptions Let You Skip the California Penalty?

California residents who qualify for an exemption owe no penalty for the months the exemption covers. Residents can claim exemptions directly on California Form 3853 with the state tax return. Some exemption types can also be approved in advance through the Covered California website. The Franchise Tax Board recognizes five exemption categories: affordability, hardship, short coverage gaps, religious beliefs and incarceration. A resident can qualify for more than one type in a single calendar year.

Affordability Exemption

A California resident qualifies for the affordability exemption when the lowest-cost Bronze plan available in their rating area exceeds a set percentage of household income. MoneyGeek found that residents in high-cost rating areas such as parts of Northern California or the Central Valley are more likely to qualify for this exemption than residents in urban metros, where more insurers participate and drive Bronze premiums lower.

The short-gap exemption requires no documentation. If you went without coverage in January and February and got a Covered California plan starting March 1, your penalty is $0.

Residents must use Covered California's exemption tool to confirm affordability before claiming the exemption on Form 3853.

Short Coverage Gap Exemption

California grants a short-gap exemption for residents who went uninsured for fewer than three consecutive months during the calendar year. A resident uninsured in January and February who got a qualifying Covered California plan starting March 1 owes no penalty for those two months. Only one short-gap exemption applies per calendar year. A second uninsured gap of any length in the same year is penalized at the standard monthly rate with no exemption available.

Hardship and Religious Exemptions

California grants hardship exemptions for documented circumstances including domestic violence, eviction, natural disaster, death of a close family member or bankruptcy. A religious conscience exemption is available to members of religious sects whose beliefs oppose health insurance as a matter of doctrine. Both types require documentation submitted through the Covered California exemption portal or attached to Form 3853.

Incarceration and Immigration Exemptions

Residents who were incarcerated for part of the year and residents in certain immigration statuses that make them ineligible for Covered California enrollment can claim an exemption for those months. Each exemption applies only to the calendar months when the qualifying condition was in effect, not the full year. Current exemption eligibility details and documentation requirements are published at ftb.ca.gov.

Bottom Line

California's health insurance penalty is $950 per uninsured adult in 2026, or 2.5% of gross income if that amount is higher. Enrolling in a Covered California plan, employer coverage or Medi-Cal before December 31 removes the penalty entirely. Missing open enrollment doesn't mean you're stuck. A special enrollment period or qualifying exemption can still eliminate the charge.

Avoiding California Health Insurance Penalty: FAQ

These answers cover the California health insurance penalty for 2026, including how much you owe, what coverage qualifies and how to claim an exemption.

How much is the California health insurance penalty in 2026?

The 2026 California health insurance penalty is $950 per uninsured adult or 2.5% of household gross income above the state filing threshold, whichever is higher. Each uninsured dependent child adds $475. A family of four owes at least $2,850 annually, per the Franchise Tax Board.

What happens if I was uninsured for only part of 2026?

The Franchise Tax Board prorates the penalty by month. A resident uninsured for three months owes 25% of the annual flat penalty, not the full-year total. One short coverage gap of fewer than three consecutive months qualifies for an exemption claimed on Form 3853.

Does the California penalty apply if I have out-of-state coverage?

Out-of-state coverage qualifies as minimum essential coverage under California's mandate as long as the plan is ACA-compliant. Employer-sponsored group plans offered by out-of-state employers satisfy the requirement for enrolled California residents. Short-term or non-ACA-compliant out-of-state plans don't qualify.

What if no plan in 2026 is affordable for my household?

California's affordability exemption applies when the lowest-cost Bronze plan in your rating area exceeds a set share of household income. Apply through the Covered California exemption tool or claim it on Form 3853 with your state return. Residents below California's filing threshold owe no penalty regardless of coverage.

Does catastrophic coverage count toward the California mandate?

Catastrophic health plans purchased through Covered California qualify as minimum essential coverage under the state mandate. Eligibility is limited to adults under 30 and those who qualify for a hardship or affordability exemption, per Covered California. Catastrophic plans sold outside Covered California that aren't ACA-compliant don't satisfy the requirement.

Will the Franchise Tax Board notify me if I owe a penalty?

The penalty is self-reported on Form 3853 filed with your California state return. The Franchise Tax Board sends notices when a reported penalty goes unpaid or when reported coverage information doesn't match insurer records. Unpaid penalties are collected from future state refunds.

Does my spouse's employer plan satisfy the mandate for me?

A spouse's employer plan qualifies as minimum essential coverage for all dependents actually enrolled on the plan. Eligibility alone doesn't satisfy the requirement. A spouse who is eligible for but not enrolled in their partner's employer plan remains subject to the Franchise Tax Board penalty for each uncovered month.
