If you live in Arizona and need health insurance, the Affordable Care Act (ACA) Marketplace could save you hundreds of dollars a month on coverage. Arizona uses the federal Marketplace at HealthCare.gov, where seven insurance companies offer plans for 2026. Whether you qualify for subsidies depends on your household income, family size, and a few other factors.
This guide breaks down everything you need to know about Arizona ACA eligibility for 2026, including current income limits, what changed from 2025, and exactly how to sign up.
How ACA Eligibility Works in Arizona
Arizona residents enroll in ACA Marketplace plans through HealthCare.gov. The state does not run its own exchange. To be eligible to purchase a Marketplace plan, you must meet these basic requirements:
- You must live in Arizona
- You must be a U.S. citizen or lawfully present in the country
- You cannot be currently incarcerated
- You cannot be enrolled in Medicare
Meeting these requirements lets you buy a plan on the Marketplace. But the bigger question for most people is whether you qualify for financial help paying for it.
2026 Income Limits for ACA Subsidies in Arizona
Financial assistance through the ACA comes in two forms: premium tax credits (which lower your monthly bill) and cost-sharing reductions (which lower your out-of-pocket costs when you use care). Your eligibility for each depends on where your household income falls relative to the federal poverty level (FPL).
For 2026, premium tax credits are available to Arizona residents with household incomes between 100% and 400% of the FPL. This is a notable change from recent years, because the enhanced subsidies from the Inflation Reduction Act expired at the end of 2025. Those enhanced subsidies had removed the upper income cap entirely, making subsidies available even above 400% FPL. For 2026, the 400% FPL ceiling is back in effect.
2026 ACA Premium Tax Credit Income Limits (100% to 400% FPL)
| Household Size | Minimum Income (100% FPL) | Maximum Income (400% FPL) |
|---|---|---|
| 1 | $15,960 | $63,840 |
| 2 | $21,640 | $86,560 |
| 3 | $27,320 | $109,280 |
| 4 | $33,000 | $132,000 |
| 5 | $38,680 | $154,720 |
| 6 | $44,360 | $177,440 |
If your income falls below 100% FPL, you likely will not qualify for Marketplace subsidies. However, you may qualify for Arizona Medicaid (called AHCCCS), which covers adults with incomes up to 138% FPL.
Cost-Sharing Reduction Income Limits
Cost-sharing reductions (CSRs) are available if your income is at or below 250% of the FPL and you choose a Silver-level plan. CSRs lower your deductibles, copays, and maximum out-of-pocket costs.
| Household Size | CSR Eligible (up to 250% FPL) |
|---|---|
| 1 | $39,900 |
| 2 | $54,100 |
| 3 | $68,300 |
| 4 | $82,500 |
To get CSR benefits, you must select a Silver plan. The reduced cost-sharing is applied automatically when you enroll.
What Changed for 2026: Enhanced Subsidies Expired
The biggest shift for 2026 is the expiration of the enhanced ACA subsidies that were in place from 2021 through 2025. Here is what that means in practical terms:
- Income cap is back. If your household income is above 400% FPL, you no longer qualify for premium tax credits. Under the enhanced rules, there was no upper limit.
- Higher costs for many enrollees. About 90% of Arizona Marketplace enrollees received premium subsidies in 2025, paying an average of approximately $69 per month after subsidies. Without the enhanced credits, many will see higher premiums for 2026.
- Rate increases compound the impact. Arizona insurers approved significant rate increases for 2026, with some carriers raising rates by 30% to 49% before subsidies. For example, Blue Cross Blue Shield of Arizona HMO plans increased by approximately 49%, and UnitedHealthcare of Arizona increased by approximately 44%.
If you had a Marketplace plan in 2025, it is important to check whether you still qualify for assistance and how much your costs may have changed.
Arizona Medicaid (AHCCCS): The Other Path to Coverage
If your income is too low for ACA subsidies (below 100% FPL) or falls within the Medicaid range, Arizona's Medicaid program called AHCCCS (Arizona Health Care Cost Containment System) may cover you instead. Arizona expanded Medicaid, so adults without dependent children can qualify.
AHCCCS Income Limits (138% FPL)
| Household Size | Monthly Income | Annual Income |
|---|---|---|
| 1 | $1,835 | $22,025 |
| 2 | $2,482 | $29,782 |
| 3 | $3,128 | $37,539 |
| 4 | $3,795 | $45,540 |
AHCCCS covers medical, dental, vision, prescription drugs, mental health services, and hospitalization. You can apply online through Health-e-Arizona Plus or by calling 1-855-432-7587.
Children in families with incomes up to 200% FPL may qualify for KidsCare, Arizona's Children's Health Insurance Program (CHIP).
ACA Insurance Companies in Arizona for 2026
Seven insurers offer Marketplace plans in Arizona for 2026. Coverage areas vary by carrier, so not every insurer is available in every county.
- Cigna HealthCare of Arizona
- Blue Cross Blue Shield of Arizona (HMO plans only)
- Imperial Insurance
- Arizona Complete Health (Health Net of Arizona)
- Oscar Health Plan
- UnitedHealthcare of Arizona
- Antidote Health Plan of Arizona
Notable changes: Aetna CVS Health/Banner Health exited the Arizona market at the end of 2025. Blue Cross Blue Shield of Arizona discontinued its PPO plans and now offers only HMO coverage. If you had a plan with either of these options in 2025, you needed to select a new plan during open enrollment.

Step 6: Pay Your First Premium
Your coverage does not start until you pay your first monthly premium. Set up payment directly with your insurance company after enrolling.
Enrollment Periods for Arizona
Open Enrollment for 2026 coverage ran from November 1, 2025 through January 15, 2026. If you missed this window, you cannot enroll in a Marketplace plan unless you qualify for a special enrollment period.
Special Enrollment Periods allow you to sign up outside of open enrollment if you experience a qualifying life event, such as:
- Losing other health coverage (job loss, aging off a parent's plan, losing Medicaid)
- Getting married or divorced
- Having or adopting a child
- Moving to a new area with different plan options
- Changes in household income that affect eligibility
American Indians and Alaska Natives can enroll in Marketplace coverage at any time throughout the year without needing a qualifying life event.
Next Open Enrollment for 2027 coverage will run from November 1, 2026 to December 15, 2026. Note that this is a shorter window than in previous years due to a federal rule change.
Tips to Lower Your Arizona Health Insurance Costs
-
Choose a Silver plan if your income is under 250% FPL. Cost-sharing reductions only apply to Silver plans, and they can significantly reduce what you pay at the doctor or hospital.
-
Report income changes promptly. If your income drops during the year, you may qualify for larger subsidies or even Medicaid. Update your HealthCare.gov application to adjust your assistance.
-
Use in-network providers. Marketplace plans have provider networks. Staying in-network keeps your costs lower and avoids surprise bills.
-
Look into AHCCCS if your income is near the cutoff. If you earn close to 138% FPL, compare Medicaid coverage (which has no premiums and minimal cost-sharing) with a subsidized Marketplace plan.
-
Get free help from a Navigator or broker. Arizona has certified application counselors and Navigators who can help you apply at no cost. Find local help at HealthCare.gov's Find Local Help tool.
Frequently Asked Questions
What is the income limit for ACA subsidies in Arizona for 2026?
For 2026, you need a household income between 100% and 400% of the federal poverty level to qualify for premium tax credits. For an individual, that means between $15,960 and $63,840 per year. For a family of four, the range is $33,000 to $132,000.
Can I still sign up for a Marketplace plan if I missed open enrollment?
Only if you qualify for a special enrollment period through a qualifying life event like losing other coverage, getting married, having a baby, or moving. American Indians and Alaska Natives can enroll year-round. Otherwise, you will need to wait for the next open enrollment starting November 1, 2026.
What if my income is below the ACA minimum?
If your income falls below 100% FPL, you likely qualify for AHCCCS (Arizona Medicaid) instead of Marketplace subsidies. Arizona expanded Medicaid, so most adults with incomes up to 138% FPL can get coverage through AHCCCS. Apply at Health-e-Arizona Plus.
Did ACA premiums go up in Arizona for 2026?
Yes. Arizona saw significant rate increases for 2026, with approved increases ranging from about 18% to 49% depending on the insurer. However, if you qualify for premium tax credits, your subsidies will offset some or all of the increase. The amount you pay depends on your income and the benchmark Silver plan in your area.
What is the difference between AHCCCS and ACA Marketplace coverage?
AHCCCS is Arizona's Medicaid program for low-income residents (up to 138% FPL for adults). It has no monthly premiums and minimal out-of-pocket costs. ACA Marketplace plans are private insurance plans available to people with incomes generally between 100% and 400% FPL, with subsidies to help reduce costs. If you qualify for AHCCCS, you are not eligible for Marketplace subsidies.
Are the enhanced ACA subsidies still available in 2026?
No. The enhanced subsidies from the Inflation Reduction Act expired at the end of 2025. For 2026, subsidies follow the original ACA rules, which means they are available only for incomes between 100% and 400% FPL, and the required premium contribution percentages are higher than they were under the enhanced rules.
