No, it is not illegal to go without health insurance in Arizona. The state has never imposed its own coverage requirement, and the federal penalty under the Affordable Care Act was reduced to $0 starting with the 2019 tax year. You will not owe anything on your state or federal return for being uninsured. What you lose is the financial protection insurance provides, and in a serious medical event that gap can cost tens or hundreds of thousands of dollars.
No Penalty, But Real Financial Risk
The federal individual mandate technically still exists in the tax code, but the “applicable dollar amount” for the shared responsibility payment is zero and the income-based percentage is also zero.1Office of the Law Revision Counsel. 26 U.S. Code 5000A – Requirement to Maintain Minimum Essential Coverage The IRS has no mechanism to collect a penalty that does not exist.2HealthCare.gov. Exemptions From the Fee for Not Having Coverage A handful of states created their own mandates after 2019, but Arizona is not among them. There is no state tax penalty, and no pending legislation to create one.
What going uninsured actually costs is the full price of any care you receive. Hospitals and providers negotiate steep discounts with insurance companies that uninsured patients do not automatically get. A minor emergency room visit can easily run $1,000 to $3,000. A broken bone needing surgery can hit $30,000 or more. A heart attack, a cancer diagnosis, or an extended hospital stay can generate bills in the hundreds of thousands. These are the exact scenarios insurance is designed to absorb.
Protections If You’re Uninsured Right Now
Ask for a Good Faith Estimate Before Any Scheduled Care
Since January 2022, the No Surprises Act has required every licensed health care provider and facility to give uninsured or self-pay patients a written estimate of expected charges before scheduled services. If your final bill exceeds the estimate by $400 or more, you can challenge it through a federal patient-provider dispute resolution process.3Centers for Medicare & Medicaid Services. No Surprises Act Overview of Key Consumer Protections Request the estimate in writing. Providers are required to produce one, but you get more reliable numbers when you ask up front.
Apply for Hospital Financial Assistance
Federal tax law requires every nonprofit hospital to maintain a written financial assistance policy that covers at least all emergency and medically necessary care. These policies must spell out who qualifies, how to apply, and how the hospital calculates charges.4Internal Revenue Service. Financial Assistance Policies (FAPs) Income thresholds vary. Some hospitals offer free care up to 200% of the federal poverty level, others extend discounts to 400% or higher. If you are facing a large bill from a nonprofit hospital, ask the billing department for a financial assistance application before you assume you owe the full amount. Most patients never ask.
Know How Medical Debt Hits Your Credit
Since 2023, Equifax, Experian, and TransUnion have voluntarily removed medical debts of $500 or less from credit reports, along with any medical debt that was later repaid. The CFPB finalized a broader rule in early 2025 that would have banned all medical debt from credit reports, but a federal court vacated that rule in July 2025 at the joint request of the agency and the plaintiffs.5Consumer Financial Protection Bureau. CFPB Finalizes Rule to Remove Medical Bills From Credit Reports Unpaid medical debt over $500 can still appear on your credit report and lower your score.

The Health Insurance Marketplace
Arizona uses the federal marketplace at HealthCare.gov rather than running its own exchange. Plans are organized into Bronze, Silver, Gold, and Platinum tiers, with Bronze carrying the lowest premiums and highest out-of-pocket costs and Platinum doing the reverse. Depending on your household income, you may qualify for a premium tax credit that reduces your monthly payment.
People under 30, or anyone over 30 with a hardship or affordability exemption, can also buy a catastrophic plan. Premiums are very low, deductibles are high, and the plan covers at least three primary care visits per year before you hit the deductible.8HealthCare.gov. Catastrophic Health Plans
Employer Coverage
Under the ACA, employers with 50 or more full-time employees must offer health coverage to workers who average at least 30 hours per week.9Internal Revenue Service. Identifying Full-Time Employees If you work 30 or more hours a week for a large employer and have not been offered insurance, raise it with HR.
COBRA After Leaving a Job
If you lose employer coverage because of a job loss or a reduction in hours, federal COBRA rules let you continue that same group plan for up to 18 months. You pay the full premium yourself, including the share your employer used to cover, plus a 2% administrative fee, so the cost is significantly higher than what you paid as an employee. For certain qualifying events such as divorce or the death of a covered employee, dependents may extend COBRA coverage for up to 36 months.10U.S. Department of Labor. FAQs on COBRA Continuation Health Coverage for Workers You have 60 days from receiving the COBRA election notice to decide.
Short-Term Plans
Arizona allows short-term limited-duration insurance with an initial term of up to 12 months and a total duration, including renewals, of up to 36 months.11Arizona Legislature. Arizona Code 20-1384 – Short-Term Limited Duration Insurance These plans typically cost less than marketplace coverage, but they can deny coverage or charge more based on pre-existing conditions, exclude entire categories of care, and impose annual or lifetime caps. They do not count as qualifying coverage under ACA standards. If you are generally healthy and need a bridge between jobs, a short-term plan may fit. If you have an ongoing condition, the gaps can be expensive.
When You Can Enroll
Marketplace plans are not available year-round. Open Enrollment for 2026 coverage runs November 1 through January 15, 2026. Enroll by December 15 for coverage starting January 1. Enroll between December 16 and January 15 for coverage starting February 1.12Centers for Medicare & Medicaid Services. Marketplace 2026 Open Enrollment Fact Sheet
Outside that window, you can sign up only if you experience a qualifying life event that opens a Special Enrollment Period. Common triggers include:
- Losing existing coverage, including job loss, aging off a parent’s plan at 26, or losing Medicaid or CHIP eligibility
- Changes in household, such as marriage, having or adopting a child, or gaining a dependent through a court order
- Moving to a new ZIP code or county where different plans are available, or moving to the U.S. from abroad
- An income drop that makes you newly eligible for marketplace savings, or newly gaining lawful immigration status
- Enrollment errors caused by a technical problem or misinformation from an official enrollment assister
Most Special Enrollment Periods last 60 days from the qualifying event.13Centers for Medicare & Medicaid Services. Understanding Special Enrollment Periods Miss that window and you wait for the next Open Enrollment.
What Changed for Premium Tax Credits in 2026
The enhanced premium tax credits that kept marketplace premiums lower from 2021 through 2025 expired at the end of 2025. Congress was weighing an extension as of early 2026, but until legislation is signed, many enrollees face higher premiums than in prior years. The standard premium tax credit remains available for households earning between 100% and 400% of the federal poverty level.
If you take the credit in advance, applied directly to your monthly premium, you must reconcile it on IRS Form 8962 when you file. Starting with the 2026 tax year, there is no cap on how much excess credit you have to repay if your actual income comes in higher than you estimated. The full overpayment gets added to your tax bill.14Internal Revenue Service. Updates to Questions and Answers About the Premium Tax Credit Report income changes to the marketplace promptly throughout the year to keep advance payments accurate.
