Every year, millions of Americans go without health insurance, and one of the most common questions they ask is whether they are breaking the law. The short answer: no. Going uninsured is not a crime anywhere in the United States, and in 45 states there is no financial penalty of any kind.
The longer answer depends on where you live. A handful of states run their own “individual mandates” with real tax penalties that can reach thousands of dollars a year. This guide covers the federal rule, the state-by-state penalties for 2026, the exemptions that let you off the hook, and what going uninsured actually costs in practice.
What the Individual Mandate Is
The Affordable Care Act’s individual mandate, formally the individual shared responsibility provision, requires taxpayers to do one of three things, per the IRS: maintain qualifying health coverage (called minimum essential coverage), qualify for an exemption, or make a shared responsibility payment with their tax return.
It was never a criminal statute. Nobody has ever been arrested for lacking health insurance. The enforcement mechanism was always a payment collected through the tax system, which is why the whole question comes down to tax law.
The Federal Penalty Has Been $0 Since 2019
Under the Tax Cuts and Jobs Act, the federal shared responsibility payment was reduced to zero for months beginning after December 31, 2018, according to the IRS. The mandate still technically exists in federal law, but the penalty for ignoring it is $0, and federal tax forms no longer even ask about health coverage for penalty purposes.
Practically, that means that at the federal level, being uninsured in 2026 has no legal or tax consequence whatsoever.
States With Their Own Penalties in 2026
After the federal penalty zeroed out, a few states created their own mandates, mostly starting in 2019 and 2020. Per healthinsurance.org, the jurisdictions with active penalties are California, Massachusetts, New Jersey, Rhode Island, and Washington, D.C. Here is how they compare (amounts are annual unless noted, and states adjust them over time):
| Jurisdiction | Penalty basis | Typical 2026 amounts | Cap |
|---|---|---|---|
| California | Greater of 2.5% of income or flat amount | About $950/adult, $475/child; family of four minimum roughly $2,850 | Tied to average bronze plan cost |
| Massachusetts | Income- and age-based monthly schedule | Up to about $182/month (about $2,184/year max) | Based on half the cost of the lowest-priced available plan |
| New Jersey | Greater of 2.5% of income or flat amount | Minimum $695 for a single adult, up to $4,908 max | Statewide average bronze plan premium |
| Rhode Island | Greater of 2.5% of income or flat amount | $695/adult, $347.50/child | Average bronze plan premium |
| Washington, D.C. | Greater of 2.5% of income or flat amount | Sources list $695-$795/adult, $347.50-$397.50/child; family cap around $2,085-$2,385 | Average bronze plan premium |
Sources differ slightly on some 2026 figures because states adjust flat amounts for inflation at different times; the ranges above reflect the spread across the eMedicare 2026 state guide and IndexBox’s 2026 summary. Your state tax agency’s calculator gives the exact number for your household.
California
California’s penalty, collected by the Franchise Tax Board, is the greater of 2.5% of gross income above the filing threshold or a flat per-person amount (about $950 per adult and $475 per child). IndexBox’s 2026 figures put the minimum for a married couple at $1,900 and a family of four at $2,850. California uses the revenue to fund extra state premium subsidies.
Massachusetts
Massachusetts has had its mandate since 2006, predating the ACA, and it applies to adults only. Penalties scale with income and age rather than using one flat amount; for 2026 they run up to roughly $182 per month, or about $2,184 for a full uninsured year, per the eMedicare guide. Massachusetts also ties penalties to what coverage actually costs, so lower-income residents pay much less or nothing.
New Jersey
New Jersey’s Shared Responsibility Payment mirrors the old federal structure. Per the NJ Treasury, a single taxpayer owes a minimum of $695 and a maximum of $4,908, and a family of five can owe from roughly $2,443 up to $24,540 at the highest income tiers. The payment is capped at the statewide average annual bronze plan premium and is prorated by month.
Rhode Island
Per HealthSource RI, the penalty is the greater of 2.5% of household income above the filing threshold or $695 per adult and $347.50 per child, capped at the average bronze plan premium. The fee accrues at 1/12 of the annual amount per uninsured month, and a gap of one or two consecutive months triggers no penalty at all.
Washington, D.C.
D.C.’s penalty follows the familiar formula: the greater of 2.5% of income or a flat per-person amount. Healthinsurance.org lists the base amounts at $695 per adult and $347.50 per child, while IndexBox reports the inflation-adjusted 2026 figures at $795 and $397.50 with a family cap of $2,385. D.C. offers an online exemptions tool through DC Health Link.
Vermont: A Mandate With No Teeth
Vermont enacted an individual mandate effective 2020 but never attached a penalty. Per HealthCareInsider, the state instead uses tax-return coverage information for outreach, contacting uninsured residents about enrollment help. You must report your coverage status, but going uninsured costs you nothing.
Exemptions: How to Avoid a State Penalty Legally
Every mandate state offers exemptions, and they cover more people than you might expect. Using Rhode Island’s list as a representative example (most states are similar), exemptions include:
- Unaffordability. If the cheapest available plan would cost more than a set share of your income (8.05% in Rhode Island’s case), you are exempt.
- Short coverage gaps. A gap of less than three consecutive months is typically penalty-free.
- Financial hardship, such as eviction, bankruptcy, or large medical debt.
- Low income below the state tax filing threshold, which exempts you automatically.
- Religious conscience objections and membership in a recognized health care sharing ministry.
- Incarceration, living abroad, or membership in a federally recognized tribe.
You claim exemptions either on your state tax return or through the state exchange, depending on the type. If you are uninsured in a mandate state, check the exemption list before assuming you owe; if premiums genuinely strain your budget, there is a fair chance you qualify for the affordability exemption.
What Going Uninsured Actually Costs
Here is the honest framing: in most of the country, the law is the least of your worries. The real financial exposure of being uninsured is not a $695 tax penalty, it is the medical bills themselves. A single emergency room visit commonly costs more than an entire year of state penalties, and a hospitalization can reach five or six figures.
That risk cuts both ways in the penalty math. In mandate states, people sometimes discover that a subsidized bronze plan costs little more per month than the penalty they would owe anyway, which makes insurance the obvious buy. Run your subsidy numbers before defaulting to the penalty; our uninsured starter playbook walks through checking Medicaid, marketplace subsidies, and the alternatives in order, and the self-pay vs. insurance breakdown covers the catastrophic-risk tradeoff honestly. If a conventional plan is out of reach, catastrophic coverage can satisfy mandates for those who qualify.
If you do go uninsured for a stretch, be deliberate about it. Learn to look up hospital cash prices before you get care, use free and sliding-scale clinics for routine needs, and if a big bill lands, negotiate it and apply for charity care before paying anything.
The Bottom Line
It is not illegal to go without health insurance in 2026, and there is no federal penalty. Unless you live in California, Massachusetts, New Jersey, Rhode Island, or Washington, D.C., there is no state penalty either. In those five jurisdictions, expect roughly $700 to $1,000 per adult per year at minimum (more for higher earners), unless an exemption applies, and check the affordability exemption first.
Wherever you live, treat the mandate question as separate from the coverage question. The penalty is small and avoidable; unmanaged medical bills are neither. If you are uninsured right now, start with the complete uninsured playbook.
