Arizona residents enrolling in a 2026 ACA Marketplace plan face a different cost picture than the previous four years. The enhanced premium tax credits from the Inflation Reduction Act expired at the end of 2025, which means subsidy eligibility now caps at 400% of the Federal Poverty Level (FPL), and monthly premiums are higher than they were under the enhanced rules. Despite that shift, roughly 83% of Arizona Marketplace enrollees still qualified for subsidies in 2026, and cost-sharing reductions remain available for lower-income Silver plan buyers. This guide covers every major piece: Arizona's plan options, income limits, subsidy amounts, and step-by-step enrollment through Healthcare.gov.
What Changed for Arizona ACA Plans in 2026
The biggest 2026 change is the end of enhanced Inflation Reduction Act subsidies. From 2021 through 2025, those enhanced credits allowed people above 400% FPL to qualify for help, and kept required premium contributions unusually low across all income levels. Starting January 1, 2026, the rules reverted to the original ACA structure:
- Subsidies only available for incomes between 100% and 400% FPL
- Required premium contribution percentages are higher at every income level
- No more "no cap" subsidy eligibility above 400% FPL
On top of that policy change, Arizona insurers filed steep rate increases for 2026. Blue Cross Blue Shield of Arizona HMO plans raised rates roughly 49%, and UnitedHealthcare of Arizona increased rates roughly 44% before subsidies. Arizona saw a 15.6% enrollment drop for 2026, one of the steepest declines in the country, according to KFF.
Arizona ACA Subsidy Income Limits for 2026
Arizona uses the federal Healthcare.gov exchange, so ACA subsidy eligibility follows national rules. For 2026 coverage, subsidies rely on the 2025 Federal Poverty Level figures published by ASPE at HHS.
Premium tax credits (PTCs) are available when your household income falls between 100% and 400% FPL. Cost-sharing reductions (CSRs) apply for incomes at or below 250% FPL when you choose a Silver plan.
2026 Arizona ACA Subsidy Eligibility by Household Size
| Household Size | 100% FPL (Minimum) | 250% FPL (CSR Cutoff) | 400% FPL (PTC Cutoff) |
|---|
| 1 | $15,650 | $39,125 | $62,600 |
| 2 | $21,150 | $52,875 | $84,600 |
| 3 | $26,650 | $66,625 | $106,600 |
| 4 | $32,150 | $80,375 | $128,600 |
| 5 | $37,650 | $94,125 | $150,600 |
| 6 | $43,150 | $107,875 | $172,600 |
| 7 | $48,650 | $121,625 | $194,600 |
| 8 | $54,150 | $135,375 | $216,600 |
| Each additional | +$5,500 | +$13,750 | +$22,000 |
Table: Arizona ACA Income Limits, 2026 (based on 2025 FPL guidelines used for 2026 coverage year)
If your 2026 household income falls below the 100% FPL threshold shown above, you likely will not qualify for Marketplace subsidies. In Arizona, adults up to 138% FPL qualify for AHCCCS (Arizona's Medicaid program) instead. You can use the eligibility screener at CoveredUSA to find out which program fits your income and household size.
Plan Metal Tiers Available in Arizona
Arizona residents can choose from four metal tiers through Healthcare.gov. Each tier represents a different split between monthly premiums and out-of-pocket costs when you use care.
| Metal Tier | Insurer Pays | You Pay | Best For |
|---|
| Bronze | 60% | 40% | Healthy people who rarely use care |
| Silver | 70% | 30% | Most people, especially those under 250% FPL |
| Gold | 80% | 20% | People with regular healthcare needs |
| Platinum | 90% | 10% | People with high expected costs |
Silver is almost always the best choice if your income falls at or below 250% FPL because cost-sharing reductions are only available on Silver plans. A Silver plan with CSR can effectively perform like a Gold or Platinum plan at a Bronze price point for qualifying incomes.
Major insurers offering 2026 Arizona Marketplace plans include Blue Cross Blue Shield of Arizona, UnitedHealthcare, Ambetter (Centene), Oscar Health, and Cigna. Plan availability varies by county, so use Healthcare.gov to see exactly what is available in your ZIP code.
AHCCCS: Arizona Medicaid Below the Subsidy Floor
If your income falls below 100% FPL or 138% FPL, you may qualify for AHCCCS (Arizona's Medicaid program) rather than a Marketplace plan. Arizona expanded Medicaid under the ACA, so adults without dependent children can qualify.
AHCCCS 2026 income limits (at 138% FPL):
| Household Size | AHCCCS Income Limit (138% FPL) |
|---|
| 1 | $21,597 |
| 2 | $29,187 |
| 3 | $36,777 |
| 4 | $44,367 |
| 5 | $51,957 |
| 6 | $59,547 |
Table: Arizona AHCCCS Income Limits, 2026
If you qualify for AHCCCS, you generally pay $0 in monthly premiums. Apply through healthearizonaplus.gov or call 1-855-432-7587. You can also check eligibility at CoveredUSA's ACA income limits page.
KidsCare: Coverage for Arizona Children
Children in Arizona families with incomes above the AHCCCS limit but at or below 200% FPL may qualify for KidsCare, Arizona's Children's Health Insurance Program (CHIP). KidsCare covers routine checkups, immunizations, dental, vision, and hospital care at low or no cost.
Apply through AHCCCS at healthearizonaplus.gov.
How to Enroll in Arizona ACA Marketplace Plans
Arizona uses the federal Healthcare.gov exchange, not a state-run exchange. Open enrollment for 2026 coverage ran November 1, 2025 through January 15, 2026. If you missed open enrollment, you can still enroll during a Special Enrollment Period (SEP) if you experience a qualifying life event.
Open Enrollment Timeline
- Open enrollment start: November 1, 2025
- Deadline for January 1 coverage: December 15, 2025
- Final deadline: January 15, 2026
Qualifying Life Events for Special Enrollment
You have 60 days from a qualifying event to enroll. Common qualifying events in Arizona:
- Loss of job-based or other health coverage
- Marriage or divorce
- Birth or adoption of a child
- Moving to a new coverage area
- Gaining citizenship or lawful immigration status
- Losing eligibility for AHCCCS or KidsCare
- Changes in household income that affect subsidy eligibility
Step-by-Step Application Process
- Gather documents: proof of income (W-2s, pay stubs, tax return), Social Security numbers for all household members, immigration documents if applicable, and current insurance information if you have it.
- Create an account at Healthcare.gov or log in to an existing account.
- Complete the application with your household size, income, and current coverage status. Arizona's marketplace is federal, so you apply directly through Healthcare.gov, not a separate state portal.
- Review your eligibility results. The system will tell you if you qualify for AHCCCS, KidsCare, premium tax credits, or cost-sharing reductions.
- Compare plans in your county. Filter by metal tier, monthly premium, deductible, and your preferred doctors or prescriptions.
- Enroll in the plan that fits your budget and health needs. Coverage typically starts the first of the month following enrollment (or January 1 if you enroll before December 15).
- Pay your first premium. Coverage does not activate until your first payment is received by the insurer.
Documents Needed
- Social Security numbers for all household members
- Pay stubs, W-2s, or most recent federal tax return
- Employer and income information for everyone in the household
- Policy numbers for any current health insurance
- Immigration documents if applicable
Common Reasons Applications Get Denied or Delayed
- Income reported does not match IRS records (resolve by submitting documentation)
- Household size does not match tax filing records
- Immigration status cannot be verified
- Missing Social Security numbers for household members
- Application not submitted before deadline
Understanding Premium Tax Credits in Arizona
A premium tax credit reduces the monthly cost of your Marketplace plan. The credit amount is calculated based on the difference between the benchmark plan cost (second-lowest-cost Silver plan in your county) and the maximum amount you are expected to contribute based on your income as a percentage of FPL.
For 2026, the ACA contribution scale is:
| Income (% FPL) | Maximum Premium Contribution |
|---|
| 100% to 133% | 2.0% of income |
| 133% to 150% | 3.0% to 4.0% of income |
| 150% to 200% | 4.0% to 6.0% of income |
| 200% to 250% | 6.0% to 8.5% of income |
| 250% to 300% | 8.5% of income |
| 300% to 400% | 8.5% to 10.0% of income |
Table: 2026 ACA Premium Contribution Scale (original ACA rules, enhanced credits expired)
You can take the credit monthly (applied directly to your premium) or claim it as a lump sum when you file taxes. Most people take it monthly to lower their immediate out-of-pocket costs.
If your income changes during the year, report it at Healthcare.gov promptly. Under-reporting can result in repaying excess credits when you file taxes.
How Much Will You Pay in 2026?
Because Arizona's 2026 rates increased substantially, actual premiums depend on your age, county, and plan. That said, subsidies still offset a large portion of costs for qualifying Arizonans. Here are rough 2026 benchmark estimates for a single adult:
- An individual earning $20,000 per year (about 133% FPL) would expect to pay roughly 2% to 4% of income annually in premiums, or around $33 to $67 per month.
- An individual earning $35,000 per year (about 232% FPL) would pay up to 6% to 8.5% of income, or roughly $175 to $248 per month.
- An individual earning $60,000 per year (near the 400% FPL cap) would pay up to 10% of income, or roughly $500 per month.
These are estimates. Use the KFF subsidy calculator for a precise figure based on your ZIP code, age, and income.

Frequently Asked Questions
Does Arizona have its own ACA marketplace in 2026?
No. Arizona uses the federal exchange at Healthcare.gov. Residents apply through Healthcare.gov and select from Arizona-specific plans available in their county. Arizona does not operate a state-run marketplace.
When is the next open enrollment period for Arizona ACA plans?
The next open enrollment period for 2027 coverage will begin November 1, 2026 and run through January 15, 2027. If you missed the 2026 open enrollment that closed January 15, 2026, you need a qualifying life event to enroll through a Special Enrollment Period.
Can I still get subsidies if I make over $60,000 as a single person in Arizona?
Under 2026 rules, premium tax credits are only available up to 400% FPL, which is approximately $62,600 for a single adult. If your income exceeds that, you would pay full price for a Marketplace plan. This is a significant change from 2021 to 2025, when the enhanced subsidies had no income cap.
What is the cheapest ACA plan available in Arizona for 2026?
Bronze plans carry the lowest monthly premiums in Arizona but the highest out-of-pocket costs when you use care. If your income is between 100% and 250% FPL and you choose a Silver plan, cost-sharing reductions can make a Silver plan more valuable than a Bronze plan despite a slightly higher premium. The exact cheapest plan depends on your county and age.
What if I miss open enrollment and do not have a qualifying event?
If you miss Arizona's ACA open enrollment and do not have a qualifying life event, you cannot enroll in a Marketplace plan until the next open enrollment period. Short-term health plans are available but do not meet ACA standards and do not qualify for subsidies. You may still qualify for AHCCCS year-round if your income falls at or below 138% FPL.
How do I report an income change to Healthcare.gov?
Log in to your Healthcare.gov account and go to your application. Select "Report a life change" and update your projected annual income. The system will recalculate your subsidy amount. If your income dropped, your subsidy may increase immediately. If it rose above 400% FPL, your subsidy will stop. Failing to report income changes can result in a large repayment when you file your federal tax return.
Is AHCCCS the same as Arizona Medicaid?
Yes. AHCCCS (pronounced "access") is Arizona's Medicaid program, administered by the Arizona Health Care Cost Containment System. It covers adults up to 138% FPL, children up to 200% FPL through KidsCare, and pregnant individuals up to 156% FPL. Arizona expanded Medicaid under the ACA, so adults without dependent children can qualify. Apply at healthearizonaplus.gov or call 1-855-432-7587.
Where can I get free help applying for Arizona ACA marketplace coverage?
Licensed agents and navigators can help you compare plans and apply at no cost to you. Brokers are paid by insurance companies, not by you. You can also get help from the Arizona SHIP (State Health Insurance Assistance Program) at 1-800-432-4040 or azship.org for Medicare-related questions. For ACA and Medicaid, contact the AHCCCS information line at 1-855-432-7587 or use the screener at CoveredUSA.
