Is Health Insurance Required in California?

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. The federal mandate carries no financial penalty in 2026, so California residents can't rely on federal compliance to avoid state 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. Employer group plans, Covered California marketplace plans and direct-purchase plans that meet the Affordable Care Act's standards all satisfy California's minimum essential coverage requirement. ACA-compliant plans must cover essential health benefits and cannot exclude pre-existing conditions. Short-term plans don't meet these standards.

What Is the California Health Insurance Penalty?

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 $475 per uninsured dependent child under 18 for 2026. 

The income-based method applies 2.5% of household gross income above the state filing threshold, which is the minimum income at which California requires you to file a state return. The 2025 threshold for single filers under age 65 is published at ftb.ca.gov as $22,941. For a single adult earning $80,000, that calculation produces exactly $1,426.48, well above the $950 flat rate.

Single adult (full year)
$950
2.5% of gross income above filing threshold
Dependent child under 18 (full year)

$475

Half the adult flat-rate method (2.5% prorated)
Two adults, two children under 18 (full year)

At least $2,850

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 $950 flat penalty applies only to a full year without coverage. The Franchise Tax Board divides the annual amount by 12 and charges that monthly rate for each uninsured month. A single adult uninsured for two months pays $158. 

For a family of four, the same two uninsured months costs $475. Partial-year penalties are always smaller than the full-year amount, which is why counting your exact uninsured months on Form 3853 matters.

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.

MONEYGEEK EXPERT TIP

The most common Form 3853 mistake I see is filers treating their coverage gap as an all-or-nothing calculation. A single adult uncovered for three months owes $238, not the full $950. Count your uninsured months precisely before filing. The current filing threshold is published at ftb.ca.gov under Individual Shared Responsibility Penalty.

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. Medi-Cal covers low-income adults and families. CHIP, the Children's Health Insurance Program, covers children in households that earn too much for Medi-Cal but can't afford private coverage. Both satisfy the mandate at no premium cost.

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 keep qualifying health coverage every month since 2020. The Franchise Tax Board enforces it through your state tax return each year. It calculates the penalty for each month you lacked coverage or an approved exemption.   

Retroactive enrollment doesn't satisfy the mandate for months already passed. Acting before a gap opens is the only way to avoid the charge.

  1. 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. 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. 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. For 2026, that threshold is $22,025 for a single person and $45,540 for a family of four. Confirm current limits at dhcs.ca.gov.

    Apply through Covered California, your county social services office or BenefitsCal.gov. Coverage starts as early as the month of approval for qualifying households.

  4. 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. 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. Claim exemptions on California Form 3853 filed with your state return, or get advance approval 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. 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.

    People 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.

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, which lets you keep your employer health plan for up to 18 months after leaving a job at your own expense, employer coverage through a new job and Medi-Cal for income-eligible residents are the main options.

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 cheapest Bronze-tier plan in their county (Bronze plans are the lowest-premium option on Covered California, with the highest out-of-pocket costs) costs more than a set share of their household income. Residents in high-cost rating areas, including parts of Northern California and the Central Valley, are more likely to qualify than those in urban metros, where more insurers compete and push Bronze premiums lower.

    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 uninsured for fewer than three consecutive months during the calendar year. This exemption requires no documentation. A resident uninsured in January and February who got a Covered California plan by March 1 owes no penalty for those months. 

    Only one short-gap exemption applies per calendar year. A second coverage gap of any length in the same year incurs the standard monthly penalty with no exemption credit.

    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 incarcerated for part of the year, and those in immigration statuses that bar them from Covered California enrollment, can claim an exemption for those months. Each exemption applies only to the specific months when the qualifying condition was in effect. Find current eligibility details and documentation requirements 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

Most California residents owe either the $950 flat penalty or the 2.5% income-based amount, whichever is higher. These answers address the specific scenarios that change that calculation.
