Health insurance isn't required by federal law, but five states and Washington, D.C., mandate coverage. California, Massachusetts, New Jersey, Rhode Island and Washington, D.C., impose financial penalties. Vermont requires coverage reporting but charges no fine.

Exemptions exist when the least expensive ACA plan in your state costs more than 8.5% of your household income after any available subsidies. Religious objectors with documented practice history also qualify. So do people with coverage gaps shorter than 63 days.

If you go uninsured, you'll save on monthly premiums but leaves you paying full price for care. A single emergency room visit averages $2,200 out of pocket, and a hospital stay can cost tens of thousands more.

Do You Have to Have Health Insurance?

Health insurance is not required by federal law. But that simple answer masks two decades of shifting rules, and where you live determines what the mandate actually means for you today. Five states and Washington, D.C., have their own coverage mandates.

From 2014 to 2018, the Affordable Care Act (ACA), the federal law that restructured U.S. health insurance markets, required most Americans to carry health insurance or pay a federal tax penalty.

If only sick people buy insurance, premiums rise for everyone. A broader risk pool of healthy and sick enrollees kept costs lower across the entire market.

Congress ended that federal penalty in 2019. Five states and Washington, D.C., immediately built their own versions of the rule. We applied California's penalty formula to calculate that the income-based calculation overtakes the $950 flat fee at approximately $93,850 in gross income for a single adult. In many income brackets, a subsidized plan costs less per year than the state penalty.

WHAT WAS THE INDIVIDUAL MANDATE

The individual mandate was the ACA's rule requiring most Americans to carry health insurance or pay a penalty on their federal tax return each April. The penalty was the higher of two figures: a flat $695 fee per uninsured adult, or 2.5% of household income above the filing threshold. Whichever produced the larger number applied.

Congress reduced that penalty to $0 starting in 2019. The mandate still exists in federal law. No financial consequence is attached, so it carries no practical weight at the federal level. Five states and Washington, D.C., were free to create their own versions, and all six did.

A separate ACA rule, the employer mandate, still applies. Businesses with 50 or more full-time employees must offer affordable health coverage or pay their own penalties. If your employer provides insurance, that requirement hasn't changed.

States That Require You to Have Health Insurance

California, Massachusetts, New Jersey, Rhode Island, Vermont and Washington, D.C., require residents to have health insurance. Check your state's regulations before filing your taxes. Exemption criteria and coverage standards differ since each jurisdiction sets its own rules. Check your state's specific regulations to avoid penalties.    

Minimum Essential Coverage (MEC) is the legal term for health plans that qualify under state mandates. Most standard plans count: employer-sponsored insurance, ACA Marketplace plans, Medicare, Medicaid and CHIP. Short-term plans and most limited-benefit plans don't qualify as MEC in any mandate state.

California

Minimum Essential Coverage (MEC): Employer plans, Covered California plans, Medicare Parts A & C, student plans, COBRA, Tricare, government programs

Adult: $950 or 2.5% of gross income over filing threshold (whichever is higher); for full details, please visit the Franchise Tax Board website.

Short-term and limited-benefit plans don't qualify. Medicare Part B alone doesn't qualify. Exemptions via state tax return or Covered California website.

Massachusetts

Minimum Creditable Coverage (MCC): Employer plans meeting MCC standards, Health Connector plans, Medicare, MassHealth, COBRA, Tricare

150.1%–200% FPL: $26/month ($312/year); 200.1%–250% and higher amounts apply up to above 500% FPL. Full penalty amounts are on the Mass.gov TIR 26-1 page.

The affordability schedule determines if insurance costs too much. MCC covers preventive care 

and emergency services. Short-term and limited benefit plans don't meet standards.

New Jersey

Minimum Essential Coverage (MEC)

Individual: $695–$4,284; Family of five (≤$200,000 income): $2,443–$4,500. The amount varies with higher income levels, which you can find here.

Penalty caps at average Bronze-tier plan cost. System based on household income and family size per NJ Health Insurance Market Protection Act of 2018.

Rhode Island

Minimum Essential Coverage (MEC)

2.5% of yearly household income OR flat fee ($57.92/adult, $28.96/child per month without coverage), whichever is higher.

Penalty calculated monthly (1/12th annual amount per month without coverage). Total penalty capped at average Bronze-tier plan cost through HealthSource RI.

Vermont

Reporting requirement only

No penalties imposed

Only state with reporting requirement but no financial penalties. Residents over 18 report coverage status on state taxes. 

Washington, D.C.

Health insurance coverage required

$795/adult, $397.50/child; Maximum $2,385/family; 2.5% of family income over federal tax filing threshold (whichever is greater)

Exemptions via tax return or D.C. Health Link. Penalty revenue supports marketplace operations and premium assistance programs.

Health insurance requirements vary by state and change frequently. This information is for educational purposes only and should not be considered legal or tax advice. Always consult your state's official resources, a qualified insurance professional or tax advisor before making coverage decisions that may affect your legal compliance or financial situation.   

In our analysis of the six mandate penalty structures, most scale with household income rather than a fixed flat fee. Higher earners pay more for going uninsured. Lower-income residents often qualify for premium subsidies that cost less monthly than the annual fine divided by 12.   

Vermont is the only mandate state with no financial penalty. It requires residents to report their coverage status on state taxes and going without insurance carries no fine. The reporting requirement applies to all Vermont residents over 18. 

Two states cap their penalties at the average cost of a Bronze-tier plan. In our review of Rhode Island and New Jersey's penalty structures, uninsured residents in those states never pay more in fines than the cheapest ACA coverage would have cost. The penalty becomes a premium paid to the state rather than an insurer.

HEALTH INSURANCE EXEMPTIONS

A Bronze-tier plan is the least expensive ACA coverage tier. You qualify for a hardship exemption when the cheapest Bronze-tier plan in your state's marketplace costs more than 8.5% of your household income after any premium tax credits.

A Massachusetts resident earning $15,000 a year, for example, would qualify if the Bronze-tier plan costs more than $106 monthly. Check your state marketplace to confirm whether this threshold applies to your income.

Members of recognized religious groups and health care sharing ministries qualify with documented practice history. Active-duty military members, incarcerated individuals and tribal members are automatically exempt. A coverage gap shorter than 63 days doesn't trigger penalties in any mandate state.

Which Situations Put You at the Highest Financial Risk Without Coverage?

Three situations account for most uninsured coverage gaps we see in health care cost data. In each one, a single decision in the days after the triggering event determines whether you stay covered or spend months waiting for open enrollment.

  1. 1
    You Left a Job That Provided Health Insurance

    Employer-sponsored coverage ends on your last day of employment. Some employers end it that same day, others cover the rest of the month. Check your HR documentation for the exact date. COBRA lets you continue that same coverage, but you pay the full premium cost your employer previously covered, plus a 2% administrative fee. Compare COBRA against marketplace plans before defaulting to it.

  2. 2
    You're Turning 26 and Aging Off a Parent's Plan

    ACA rules let most young adults stay on a parent's health plan until their 26th birthday. After that, you have a 60-day special enrollment window to get your own coverage. Miss that window and you'll wait until the next open enrollment period, which is from November 1 through January 15 in most states.

  3. 3
    You're Between Jobs and Considering a Coverage Gap

    A coverage gap shorter than 63 days doesn't trigger financial penalties in any mandate state. A gap of 63 days or more leaves you exposed to full medical costs for any illness or injury that occurs during that window. A subsidized marketplace plan through HealthCare.gov is worth the cost.

What Are the Consequences of Going Without Insurance?

Without coverage, you pay the full price for every medical service, with no insurer negotiating rates on your behalf. A single emergency room visit averaged $2,200 in 2023 according to federal health expenditure data, and that's for a non-critical case. 
In our research on health care cost patterns, the bills that hit hardest are rarely from a single event. One emergency room visit often generates separate charges: facility fees, physician fees and any imaging or lab work ordered during the visit, each billed independently.

The financial exposure extends beyond one bill. Routine follow-up care, prescriptions, imaging and specialist visits all carry separate out-of-pocket costs without coverage. A connected series of medical events can easily reach tens of thousands of dollars.

  1. 1
    You Pay Full Price for All Medical Care

    Hospitals bill uninsured patients at the chargemaster rate, the full list price that is often two to four times what an insurer pays for the same service. A doctor visit that costs an insured patient a standard copay can cost several times more without coverage. There are no negotiated rates to fall back on.

  2. 2
    State Fines Add Cost Without Adding Any Coverage

    California, Massachusetts, New Jersey, Rhode Island and Washington, D.C., impose annual tax penalties on residents without coverage. California's penalty is $950 for most residents and rises above $2,000 for those earning over approximately $93,850. That fine doesn't provide any health coverage or reimburse any medical costs.

  3. 3
    Medical Debt Can Outlast the Medical Event

    Medical bills are among the leading causes of personal bankruptcy in the United States, per research published in the American Journal of Public Health. Without insurance, one hospitalization can generate tens of thousands of dollars in debt. That debt can damage your credit score and stay with you financially for years after you've physically recovered.

  4. 4
    Delaying Care Often Increases the Final Cost

    People without coverage often postpone medical visits to avoid bills. A minor condition caught early costs far less to treat than one that worsens over weeks. What starts as an outpatient visit can become a hospitalization that costs many times more.

  5. 5
    You Lose No-Cost Preventive Care

    Insured patients receive preventive screenings, vaccines and wellness checkups at little or no additional cost under most ACA-compliant plans. Without coverage, those visits carry full out-of-pocket fees. Most people avoid them, which raises the risk of catching a serious condition at a stage when treatment is harder and more expensive.   

    Most households in California, Massachusetts, New Jersey, Rhode Island and Washington, D.C., qualify for a subsidized plan that costs less per month than their state's annual penalty divided by 12. Enter your ZIP code to compare plans in your area.

How Much Health Insurance Should I Get?

In our research, the most common coverage mistake is choosing a plan based only on the monthly premium without thinking through what you'd owe if something went wrong. Coverage amount depends on your health use, your savings and who else is on the plan.

  • firstAidKit icon

    You have a chronic condition or take regular prescriptions

    Gold-tier and Platinum-tier plans cost more monthly but come with a lower out-of-pocket cap, the total you'd pay in a year before the insurer covers everything. For daily medications, a plan with built-in drug coverage often costs less overall than a cheaper plan with high drug costs added separately.

  • bankruptcy icon

    You're healthy and rarely need medical care

    A Bronze-tier or Silver-tier plan, with a high deductible (the amount you pay before coverage starts) keeps monthly costs low. Before choosing one, confirm you have $5,000 to $10,000 in savings for unexpected costs. Without that cushion, one accident erases months of premium savings.

  • family icon

    You're covering a family that includes older members

    Older family members need more frequent care than healthy young adults. I recommend checking whether the plan uses per-person deductibles rather than a family aggregate. With an aggregate, one member's high costs can exhaust the shared deductible for everyone before year-end.

  • doctor icon

    Your primary concern is staying with your current doctors

    Confirm your doctors, specialists and preferred hospital are in-network before choosing a plan. Out-of-network care costs two to three times more, and some plans exclude it entirely. The lowest monthly premium won't stay low after you factor in those visits.

HOW TO REDUCE WHAT YOU PAY FOR HEALTH INSURANCE
  • Check whether you qualify for premium tax credits before assuming a marketplace plan is unaffordable. Many people earning between 100% and 400% of the federal poverty level pay far less monthly than the unsubsidized list price. In 2026, that range is $15,960 to $63,840 for a single adult. Enter your income at HealthCare.gov to see your subsidy amount before comparing plans.
  • Use in-network providers for every non-emergency service. Out-of-network care costs two to three times more than in-network rates, and some plans exclude it entirely. A single out-of-network specialist visit can cost more than several months of premiums combined.
  • Match your deductible to your savings. A high-deductible plan saves money monthly only if you can cover the full deductible out of savings without going into debt. The break-even point depends on how often you use care and how large your emergency fund actually is.

Is Health Insurance Required by Law

Health insurance isn't required by federal law. Five states and Washington, D.C., require it and penalize residents who go uninsured. Without coverage, you pay full price for care, and a single hospitalization can generate more debt than a year's worth of premiums would have cost.

Coverage level depends on your health, your savings and your family's needs. If you live in California, Massachusetts, New Jersey, Rhode Island or Washington, D.C., confirm your current plan qualifies as MEC before your next tax filing. Uninsured residents should check HealthCare.gov before open enrollment opens November 1. Save Forms 1095-A, 1095-B and 1095-C with your annual tax records.
