Do You Get Penalized for Not Having Health Insurance?

Federal Individual Mandate: Zero Dollar Penalty Since 2019

From 2014 through 2018, the Affordable Care Act required most Americans to carry minimum essential coverage or pay a tax penalty calculated as the greater of a flat dollar amount per person or a percentage of household income. The Tax Cuts and Jobs Act of 2017 reduced that payment to $0 effective January 1, 2019.

When you file your federal return today, the IRS no longer asks you to report months of coverage or pay a shared responsibility payment. According to the IRS ACA filing guidance, the federal penalty for lacking coverage is zero for 2019 and all later tax years. Healthcare.gov confirms the same: there is no federal fee for going without health insurance after 2018.

That federal change does not erase state-level rules. If you live in a jurisdiction with its own individual mandate, your state tax return is where penalties are calculated and collected — not on your federal 1040. For the legal distinction between penalties and criminal liability, see our companion article on whether it is illegal to not have insurance.

Do You Get Penalized for Not Having Health Insurance at the State Level?

After the federal penalty dropped to zero, California, Massachusetts, New Jersey, Rhode Island, Vermont, and the District of Columbia kept or adopted their own coverage requirements. Each jurisdiction defines qualifying coverage, exemption categories, and penalty formulas differently. If you were uninsured for any month and live in one of these areas, you must address coverage on your state return or risk an additional tax bill.

States enforce mandates through their tax agencies — the California Franchise Tax Board (FTB), Massachusetts Department of Revenue, New Jersey Division of Taxation, and comparable agencies in Rhode Island, Vermont, and D.C. None of these programs involve arrest or incarceration. The consequence is a line-item addition to your state tax liability when you file.

Residents of all other states face no state-level health insurance penalty as of 2026, though uninsured patients still face full medical costs without an out-of-pocket maximum.

State Individual Mandate Penalty Comparison (2026)

The table below compares how each mandate jurisdiction structures its penalty, which form you file, and where to verify current amounts. Figures reflect tax year 2025 returns filed in 2026; always confirm updated numbers on official state sites before submitting.

Penalties are calculated monthly in most mandate states — you owe only for months without qualifying coverage or a valid exemption, not necessarily the full annual amount. California's FTB publishes an online Penalty Estimator that walks through household size, income, and uncovered months. Massachusetts uses a tiered schedule tied to income brackets rather than a single flat rate.

Which Plan Types Satisfy Minimum Essential Coverage?

Minimum essential coverage is the federal standard that mandate states adopt. Here is how common plan types are treated:

• Employer-sponsored coverage: Group health plans from your employer satisfy the mandate if they provide minimum essential coverage. Your Form 1095-C documents months of employer coverage for state filing purposes.
• ACA marketplace plans: Plans purchased through Healthcare.gov or your state exchange (Covered California, Health Connector in Massachusetts, Get Covered NJ, etc.) qualify. Form 1095-A from the marketplace lists covered months.
• Medicare: Medicare Part A, Part B, Medicare Advantage (Part C), and Part D all count. Original Medicare enrollees can verify eligibility through SSA.gov and MyMedicare.gov.
• Medicaid and CHIP: Full-benefit Medicaid and Children's Health Insurance Program coverage satisfy the mandate in every state that imposes one. Limited-benefit Medicaid programs may not qualify — check your state's definition.
• COBRA continuation: If your COBRA plan provides minimum essential coverage, those months count. COBRA is often the fastest way to close a gap after job loss before marketplace enrollment.

Partial-year coverage is handled month by month. If you had employer coverage January through June and marketplace coverage July through December, you report twelve covered months and owe no penalty. Gaps of even one month without coverage or an exemption can trigger a partial penalty in California, Massachusetts, and other mandate states.

How to Report Coverage and Claim Exemptions on State Tax Returns

Federal returns no longer include a health coverage checkbox, but state returns in mandate jurisdictions do. The process varies:

1. Gather Form 1095-A, 1095-B, or 1095-C. These document who was covered and for which months. Marketplace enrollees receive 1095-A; employers send 1095-C; insurers and government programs issue 1095-B.
2. Complete your state mandate form. California residents file Form FTB 3853 with their state return. Massachusetts filers attach Schedule HC. New Jersey taxpayers complete the Health Insurance Mandate worksheet with Form NJ-1040.
3. Apply for exemptions before filing if needed. Hardship, religious conscience, income below the filing threshold, and short coverage gaps may qualify. California processes some exemptions through Covered California; Massachusetts routes applications through the Health Connector.
4. Enroll through a Special Enrollment Period if you lost coverage mid-year. Job loss, marriage, and other qualifying events open 60-day enrollment windows on Healthcare.gov or your state exchange — reducing uncovered months before you file.
5. Retain proof of coverage and exemption approvals. State tax agencies can audit mandate compliance for up to several years. Keep 1095 forms, enrollment confirmations, and exemption letters with your tax records.

If you had coverage for every month of the tax year, most mandate states let you check a full-year coverage box and skip detailed month-by-month reporting. Partial-year situations require line-by-line month documentation — this is where filing errors most often produce unexpected penalty bills.

Weak vs. Strong Tax Filing Language (Before & After)

State tax reviewers process thousands of returns during filing season. Specific form references and 1095 line codes allow auditors to verify your claim without sending a notice.

When This Won't Work: Coverage That Does Not Satisfy the Mandate

Patients often assume any health plan they pay for satisfies state mandate requirements. That assumption is wrong for several common products:

• Short-term health insurance: These plans typically last less than 12 months and exclude pre-existing conditions, maternity, and mental health. Under ACA rules, they are not minimum essential coverage. California, Massachusetts, New Jersey, and other mandate states will assess penalties even if you held a short-term policy all year.
• Health care sharing ministries: Monthly sharing contributions are not insurance premiums, and these arrangements are not regulated as health plans. They generally do not satisfy individual mandate requirements in any mandate state.
• Fixed-indemnity and accident-only plans: Supplemental policies that pay fixed cash amounts per event — not comprehensive medical coverage — do not count.
• Some limited-benefit Medicaid programs: Emergency-only or family planning-only Medicaid may not meet minimum essential coverage standards. Verify with your state Medicaid office before relying on it for mandate compliance.
• Foreign travel insurance: Policies covering medical care abroad during travel do not substitute for domestic minimum essential coverage.

Employer, Marketplace, Medicare, and Medicaid: Penalty Rules by Plan

Employer plans: If your employer offered affordable minimum essential coverage and you declined it, you may owe a state penalty for uninsured months — declining employer coverage does not automatically grant an exemption. Your employer's Form 1095-C, Part III, Line 14 codes document which months you were offered and enrolled in coverage.

Marketplace plans: Enroll through Healthcare.gov or your state exchange during open enrollment (November 1 – January 15 in most states) or during a Special Enrollment Period. Premium tax credits reduce costs for households earning 100–400% of the federal poverty level. Form 1095-A is your proof of covered months for state filing.

Medicare: Enrollment in Medicare Part A (premium-free for most people at 65) satisfies the mandate. If you delayed Part B enrollment without a qualifying reason, you may face Medicare late-enrollment penalties separate from ACA mandate penalties — these are different programs administered through SSA.gov and CMS.

Medicaid: Full-benefit Medicaid eliminates mandate penalties for covered months. Apply through your state Medicaid portal or Healthcare.gov. Medicaid enrollment is available year-round for eligible applicants — there is no limited open enrollment window.

Five Mistakes That Lead to Unexpected State Penalties

1. Ignoring state mandate forms because the federal penalty is $0. Your federal 1040 and state return are separate filings. Skipping Form FTB 3853, Schedule HC, or the NJ mandate worksheet triggers automatic penalty assessments in mandate states.
2. Buying short-term coverage to avoid penalties. Short-term plans do not satisfy minimum essential coverage. Verify plan type before purchase — especially policies marketed as low-cost alternatives to marketplace coverage.
3. Not enrolling during a Special Enrollment Period after job loss. COBRA and marketplace SEPs close coverage gaps. Each uninsured month between employer coverage ending and new coverage starting adds to your state penalty calculation.
4. Failing to apply for exemptions before the filing deadline. Hardship and affordability exemptions require documentation. Submit applications through Covered California, the Massachusetts Health Connector, or your state's designated portal — not as an afterthought on your tax return.
5. Discarding Form 1095-A, 1095-B, or 1095-C. These forms are the primary evidence of covered months. Without them, reconstructing coverage history for a state audit is difficult and may result in penalties for months you were actually insured.
