To get health insurance in Arizona, you take one of two routes depending on your household income: apply to AHCCCS, the state’s Medicaid program, if you qualify as lower-income, or buy a private plan through HealthCare.gov if you don’t. AHCCCS accepts applications year-round. Marketplace plans are sold during open enrollment from November 1 through January 15, with a 60-day window outside that period if you have a qualifying life event.1DIFI. 2026 Health Insurance Marketplace Open Enrollment
Which Program Fits Your Income
Your income decides where you apply. AHCCCS covers most adults with household income at or below 133% of the federal poverty level (effectively 138% after a built-in disregard). In 2026 that’s roughly $1,769 a month for a single person and about $3,658 a month for a family of four.2AHCCCS. 615 Income Standards If you qualify, coverage is free or very low cost.3AHCCCS. State Plan Under Title XIX of the Social Security Act – State Arizona
Children can qualify even if the parents don’t. KidsCare, Arizona’s CHIP program, covers kids in households with income up to 225% of the federal poverty level, with small monthly premiums tied to income.4AHCCCS. KidsCare – Arizona’s Children’s Health Insurance Program (CHIP) It’s worth checking KidsCare separately for the children in your household even if the adults are shopping on the marketplace.
If your income is too high for AHCCCS, you’ll buy a plan through HealthCare.gov, the federal marketplace Arizona uses. Both paths require you to live in Arizona and be lawfully present in the United States. The state verifies residency through data matching with the Arizona Department of Transportation or documents like a lease or utility bill. Lawful presence is confirmed through records such as a U.S. passport, naturalization certificate, or permanent resident card.5eCFR. 45 CFR 155.305 – Eligibility Standards If the marketplace can’t verify your immigration status automatically, you’ll have at least 90 days to upload copies before your application is terminated.6HealthCare.gov. When the Marketplace Needs Documents to Confirm Information From Your Application
When You Can Sign Up
For plan year 2026, open enrollment in Arizona runs November 1, 2025 through January 15, 2026.1DIFI. 2026 Health Insurance Marketplace Open Enrollment Sign up by December 15 and coverage starts January 1; sign up between December 16 and January 15 and coverage starts February 1.7HealthCare.gov. When Can You Get Health Insurance?
Outside that window, you can only buy a marketplace plan if a qualifying life event happened in the past 60 days.8eCFR. 45 CFR 155.420 – Special Enrollment Periods The common triggers:
- Moving to Arizona from another state or to a new county within Arizona
- Getting married
- Having or adopting a child (coverage can be backdated to the date of birth or placement)
- Losing other coverage through a job change, divorce, or aging off a parent’s plan
Keep documentation of the event, such as a marriage certificate or termination-of-coverage letter. One trap: if you drop COBRA voluntarily, that doesn’t qualify. Running out the clock on COBRA (the full 18 or 36 months) does.
AHCCCS and KidsCare have no enrollment window. You can apply any day of the year, and federal rules require the state to process most Medicaid applications within 45 days.10eCFR. 42 CFR 435.912 – Timely Determination and Redetermination of Eligibility
What to Gather Before You Apply
Both AHCCCS and the marketplace use the same core information, so pulling these together once covers either path:
- Social Security numbers for everyone in your household, plus proof of citizenship or lawful presence
- Recent W-2s, pay stubs, or your most recent tax return; self-employed applicants should estimate net self-employment income for the coming year
- Name, address, and phone number for each working household member’s employer, plus details on any employer-sponsored coverage offered to you
- Your tax filing status and who you claim as dependents
Eligibility is based on your modified adjusted gross income, which includes wages, investment income, and additions like untaxed foreign income and tax-exempt interest.11Internal Revenue Service. Modified Adjusted Gross Income You’re estimating what you expect to earn during the coverage year, not just what you earned last year.12HealthCare.gov. What’s Included as Income Getting that estimate close matters: underestimate and you owe money back at tax time; overestimate and you leave savings on the table all year.
How to Apply
AHCCCS and KidsCare
The main application portal is Health-e-Arizona Plus (HEAplus), which also handles nutrition assistance and cash assistance in the same form.13Arizona Department of Economic Security. Health-e-Arizona Plus Application for Benefits You can also print a paper application and mail it to AHCCCS at 150 N. 18th Ave., Phoenix, AZ 85007, or get in-person help from one of more than 150 community partner organizations around the state.14AHCCCS. Apply for AHCCCS Health Insurance/KidsCare
Marketplace Plans
Apply on HealthCare.gov, by phone at 1-800-318-2596, or through a certified application counselor or licensed insurance broker. Navigators and certified counselors give free help and can’t charge you. Licensed brokers are also free to you because the insurer pays them, though they may focus on carriers they represent.
After you submit, you’ll get an eligibility notice. For AHCCCS, it tells you whether you’re approved for Medicaid or KidsCare. For the marketplace, it lists the plans you can buy and the subsidy you qualify for. If you applied through HealthCare.gov but your income turns out to be low enough for AHCCCS, your application is forwarded to the state automatically.
Subsidies That Lower What You Pay
Marketplace shoppers can get two separate forms of help.
Premium tax credits reduce your monthly bill. They’re available between 100% and 400% of the federal poverty level, which in 2026 means a single person earning between $15,960 and $63,840, or a family of four between $33,000 and $132,000.15ASPE – HHS.gov. 2026 Poverty Guidelines: 48 Contiguous States Enhanced premium tax credits were extended in early 2026, which may let households above 400% FPL also receive credits that cap premiums at a percentage of income. The amount is calculated automatically from the income you report.16HealthCare.gov. Federal Poverty Level (FPL)
Cost-sharing reductions lower your deductibles, copays, and out-of-pocket maximum. They apply only to Silver plans. For households between 100% and 150% of the poverty level, a Silver plan with cost-sharing reductions can cover up to 94% of costs instead of the standard 70%.17HealthCare.gov. Health Plan Categories: Bronze, Silver, Gold and Platinum That’s why Silver is usually the smarter pick for lower-income shoppers, even when Bronze premiums look cheaper.
If your employer offers coverage, you generally can’t get a premium tax credit unless the employer plan is unaffordable. For 2026, employer coverage counts as unaffordable when your share of the employee-only premium is more than 9.96% of household income. Above that threshold, you can turn down the employer plan and buy a subsidized marketplace plan instead.18Internal Revenue Service. Revenue Procedure 2025-25
Picking a Plan
Marketplace plans are sorted by metal tier based on how costs split between you and the insurer:
- Bronze plans cover about 60% of costs. Lowest premiums, highest out-of-pocket costs when you use care.
- Silver plans cover about 70%. The only tier eligible for cost-sharing reductions.
- Gold plans cover about 80%. Higher premiums, more predictable costs when care is needed.
- Platinum plans cover about 90%. Highest premiums, lowest cost at the point of care.
No marketplace plan can charge more than $10,600 out of pocket for an individual or $21,200 for a family in 2026.19HealthCare.gov. Out-of-Pocket Maximum/Limit For 2026, eight insurance companies offer individual marketplace plans in Arizona, including Blue Cross Blue Shield of Arizona, UnitedHealthcare, Cigna, and Oscar, though not every insurer operates in every county.20DIFI. Individual Health Insurance by County Plan Year 2026
A Catastrophic tier exists for people under 30 or those with a hardship exemption. For 2026 the hardship exemption extends to people who are ineligible for premium tax credits or cost-sharing reductions based on projected household income.21U.S. Department of Health and Human Services. HHS Expands Access to Affordable Health Insurance Premiums are very low; deductibles are high.
If you want to pair your plan with a tax-advantaged savings account, look for a high-deductible health plan that qualifies for a health savings account. In 2026, HSA contribution limits are $4,400 for self-only coverage and $8,750 for family coverage, and HSA money rolls over year to year.22Internal Revenue Service. IRS Notice 2026-05 – HSA and HDHP Limits
After You Enroll
Picking a plan doesn’t start your coverage. You have to make the first premium payment, often called a binder payment, no later than 30 calendar days from your coverage effective date. Miss it and the insurer cancels your enrollment.23Centers for Medicare & Medicaid Services. Health Coverage Effectuation Job Aid
Once coverage is active, missing a premium works differently depending on whether you receive premium tax credits. If you do, federal rules give you a three-month grace period. Your insurer must keep paying claims in month one, but during months two and three providers may hold claims. If you don’t catch up by the end of month three, the plan terminates retroactively to the end of month one.24HealthCare.gov. Premium Payments, Grace Periods, and Losing Coverage Without tax credits, the grace period may be shorter depending on the insurer.
If you already have a marketplace plan and do nothing during open enrollment, the marketplace will auto-enroll you for the next year.25HealthCare.gov. Automatic Re-Enrollment Keeps You Covered That prevents a gap, but it isn’t a reason to skip open enrollment. Premiums change each year, your subsidy can shift, and if your insurer stops offering your plan you may be moved to a different plan from a different company. To cancel auto-renewal, you must do so by December 15.
If You’re Denied or Get a Smaller Subsidy Than Expected
You have 90 days from the date on your eligibility notice to appeal a marketplace decision. File online through your HealthCare.gov account or mail a letter with your name, address, and the reason you disagree.26HealthCare.gov. How to Appeal a Marketplace Decision Send copies of supporting documents, not originals.27Centers for Medicare & Medicaid Services.
