No, Arizona does not require you to have health insurance, and there is no penalty if you go without it. The state has never passed its own coverage mandate, and the federal penalty under the Affordable Care Act has been set at $0 since 2019. You will not owe anything on your state or federal tax return for being uninsured in Arizona.
No State Mandate and No Federal Penalty
Arizona has never enacted a state-level health insurance requirement. Some states created their own mandates after Congress zeroed out the federal penalty, but Arizona did not. The state does require insurers that sell individual health plans to offer coverage to anyone who applies, regardless of health status or pre-existing conditions, but that obligation runs against the insurer, not you.1Arizona Legislature. Arizona Code 20-1379 – Guaranteed Availability of Individual Health Insurance Coverage
At the federal level, the Affordable Care Act’s individual mandate technically remains on the books under 26 U.S.C. § 5000A. The Tax Cuts and Jobs Act of 2017 set the penalty amount to $0 for every year after 2018. The statute now defines the “applicable dollar amount” as $0, and the percentage-of-income calculation also yields zero.2Office of the Law Revision Counsel. 26 U.S. Code 5000A – Requirement to Maintain Minimum Essential Coverage In practical terms, your federal return asks nothing about coverage and assesses no fee for lacking it.
What Being Uninsured Actually Costs You
No penalty does not mean no risk. The real cost shows up when something goes wrong. Without insurance, you pay the provider’s full charge rather than the discounted rate insurers negotiate in advance, and those full charges can run several times higher for the same procedure. A single emergency room visit can easily produce a five-figure bill.
Medical debt remains the leading cause of personal bankruptcy filings in the United States, and research has found that roughly two-thirds of filers cite medical expenses or illness-related income loss as a contributing factor. Uninsured people are also more likely to delay or skip care, which lets conditions that could have been treated cheaply turn into expensive emergencies.
If you’re weighing whether to stay uninsured, compare the premium of even a bare-bones plan against the exposure of paying full-price for whatever happens next. The cheapest insurance is almost always less than one bad night in a hospital.
Coverage Options If You Want Insurance
Arizona residents have several routes to coverage. Which one fits depends mostly on your income and your age.
AHCCCS and KidsCare
The Arizona Health Care Cost Containment System, known as AHCCCS, is the state’s Medicaid program.3Arizona Health Care Cost Containment System. Arizona Health Care Cost Containment System Arizona expanded Medicaid under the ACA, so adults ages 19 to 64 can qualify with income up to 133% of the federal poverty level — $1,769 per month for a single person as of February 2026. Higher thresholds apply to children, pregnant women, and parents.4Arizona Health Care Cost Containment System. FPL and Income Eligibility Chart Enrollment is open year-round, and you apply through the Health-e-Arizona Plus portal.
Families who earn too much for AHCCCS but still want help covering their kids should look at KidsCare, Arizona’s Children’s Health Insurance Program. KidsCare covers children in households with income up to 225% of the federal poverty level.5Arizona Health Care Cost Containment System. KidsCare (CHIP) State Plan Amendments
The Health Insurance Marketplace
Arizona uses the federal Marketplace at HealthCare.gov rather than running its own exchange. You can compare private plans across four tiers — Bronze, Silver, Gold, and Platinum — and find out whether you qualify for premium tax credits or cost-sharing reductions.
Open Enrollment for 2026 plans ran from November 1, 2025, through January 15, 2026. Enroll by December 15 and coverage started January 1; enroll later and it started February 1.6HealthCare.gov. When Can You Get Health Insurance? Outside that window, you need a Special Enrollment Period, which is triggered by qualifying life events like losing other coverage, getting married, having a baby, moving to a new ZIP code, or a drop in household income. You generally have 60 days from the event to pick a plan.7HealthCare.gov. Getting Health Coverage Outside Open Enrollment
Catastrophic Plans
Catastrophic plans are ACA-compliant but carry high deductibles. They cover three primary care visits and certain preventive services before the deductible kicks in. To buy one, you normally must be under 30 or qualify for a hardship or affordability exemption.8HealthCare.gov. Catastrophic Health Plans Starting with the 2026 plan year, CMS is expanding access so that people who are ineligible for premium tax credits because of their income — including those above 400% FPL — can qualify for a hardship exemption and buy catastrophic coverage.9Centers for Medicare & Medicaid Services.

Short-Term Plans
Arizona allows short-term limited-duration health insurance with an initial period of up to 364 days and total duration up to 36 months. These plans are typically cheaper, but the gaps can be enormous. They are not required to cover any minimum set of benefits, can exclude pre-existing conditions, and may impose annual or lifetime dollar limits on what they pay. Every short-term policy in Arizona must display a prominent notice that the plan does not comply with ACA requirements.10Arizona Department of Insurance and Financial Institutions. Short-Term Limited-Duration Health Insurance Plans A short-term plan also does not count as qualifying coverage, so if it expires mid-year you cannot use its expiration to trigger a Special Enrollment Period on the Marketplace.
What Changes in 2026
The enhanced premium tax credits introduced during the pandemic and extended through the Inflation Reduction Act expired at the end of 2025. Congress did not renew them in the FY2025 budget reconciliation law.11United States Congress. Enhanced Premium Tax Credit and 2026 Exchange Premiums
For 2026 plan years, the income cap for premium tax credit eligibility returns to 400% of the federal poverty level. A single person earning more than roughly $63,840, or a family of four earning more than about $132,000, no longer qualifies for any premium subsidy.12Internal Revenue Service. Eligibility for the Premium Tax Credit From 2021 through 2025 there was no upper income cap at all; anyone spending more than a set percentage of income on a benchmark plan could get help. That safety net is gone.
To qualify for premium tax credits in 2026, your household income must fall between 100% and 400% of the federal poverty level — $15,960 to $63,840 for a single person, $33,000 to $132,000 for a family of four.13HealthCare.gov. Federal Poverty Level (FPL) You must also be enrolled in a Marketplace plan and not eligible for affordable employer coverage or a government program like Medicare or Medicaid.12Internal Revenue Service. Eligibility for the Premium Tax Credit If your income falls below 100% FPL, you likely qualify for AHCCCS instead.
Separately, cost-sharing reductions still lower deductibles and copays on Silver-tier Marketplace plans for households between 100% and 250% of the federal poverty level. The help is more generous at lower incomes. You must enroll in a Silver plan to receive them.
A Note on Employer Coverage
Arizona itself does not require employers to offer health insurance. The requirement comes from the ACA’s employer shared responsibility provision, which applies to businesses that averaged 50 or more full-time equivalent employees during the prior year. Smaller employers have no coverage obligation. If your employer does offer a plan, check whether the employee share of the premium for self-only coverage stays within 9.96% of your household income for 2026; an employer plan that costs more than that, or that fails the minimum value test, may actually make you eligible for premium tax credits on the Marketplace.
