Florida's 2026 ACA Open Enrollment: The Big Picture

Florida is the undisputed leader in ACA Marketplace enrollment. With more than 4.7 million residents enrolled in marketplace plans, Florida accounts for a larger share of national ACA enrollment than any other state. That scale matters because it means Florida's insurance market is highly competitive — more carriers, more plan choices, and more pressure on premiums than residents in smaller states typically see.

The 2026 Open Enrollment Period ran from November 1, 2025 through January 15, 2026. This guide covers the key dates and deadlines, the major changes that affected Florida enrollees this cycle, and how to make the most of your coverage options — including what to do if you missed the window.

One major development in the 2026 cycle: Aetna exited Florida's individual ACA marketplace at the end of 2025. Former Aetna members had a dedicated window — November 1 through December 15 — to select a replacement plan. If you were an Aetna policyholder and didn't act, you may have been auto-enrolled in a replacement plan that isn't the best fit for your needs. Review your 2026 coverage and compare alternatives if you haven't already.

2026 Open Enrollment Key Dates and Deadlines

These dates apply to all Florida residents shopping through HealthCare.gov. Florida does not have its own state-based marketplace — all enrollment goes through the federal platform. This means Florida residents follow the federal calendar exactly, with no state-specific extensions.

Why the December 15 Deadline Matters Most

The most important date in the Open Enrollment calendar is December 15. Enrolling by that date guarantees January 1 coverage — meaning no gap between your old plan ending December 31 and new coverage beginning. Enrolling after December 15 (up through January 15) gives you coverage starting February 1, leaving a potential 31-day gap if your prior coverage ended December 31. For anyone with ongoing prescriptions, regular doctor visits, or a planned procedure, that gap can be costly.

What Changed for 2026 Florida ACA Enrollees

1. Premium Increases Averaged 25%+

Florida ACA premiums increased an average of more than 25% for 2026. The primary driver was the expiration of the enhanced premium tax credits that had been in place since 2021. These enhanced credits had extended subsidy eligibility to households above 400% of the Federal Poverty Level — a change that significantly reduced net premiums for middle-income Floridians. With those enhanced credits reduced or eliminated for some income brackets, many enrollees saw their monthly premiums rise substantially.

The impact wasn't uniform. Households below 250% FPL — particularly those qualifying for Cost-Sharing Reductions on Silver plans — continued to see good value. But households earning between $55,000 and $100,000 (for a single adult) felt the premium spike most acutely.

2. Aetna's Exit from the Florida Market

Aetna's departure left hundreds of thousands of Florida ACA enrollees needing to find new coverage. The major carriers remaining in Florida's 2026 marketplace include Florida Blue (BCBS of Florida), Ambetter from Sunshine Health, Oscar Health, Molina Healthcare, UnitedHealthcare, Humana, and Cigna. Plan availability varies by county and zip code — working with a licensed agent ensures you see every option available in your specific area.

3. Shift Toward Bronze Plans

Nationally, the share of ACA enrollees selecting Bronze plans increased from 30% in 2025 to 40% in 2026 — a direct response to rising premiums. Many households sought the lowest monthly premium to manage cost increases, accepting higher deductibles in exchange. This shift was pronounced in Florida, where premium increases were above the national average.

4. Income Thresholds for Premium Tax Credits

For 2026, premium tax credit eligibility runs from 100% to 400% of the Federal Poverty Level. Key income thresholds for 2026:

• Single adult: 100% FPL = approximately $15,060 | 400% FPL = approximately $60,240
• Household of 2: 100% FPL = approximately $20,440 | 400% FPL = approximately $81,760
• Household of 4: 100% FPL = approximately $31,200 | 400% FPL = approximately $124,800

Households earning above 400% FPL lost the enhanced credit eligibility that existed under prior law, making full-price premiums a reality for many middle-income Floridians unless they qualified under other provisions.

How to Enroll in an ACA Plan in Florida: Step-by-Step

Enrolling in a Florida ACA plan during Open Enrollment is straightforward when you're prepared. Here is the process:

• Step 1 — Gather your information. Social Security number, estimated annual household income for the coverage year, names and birthdates of all household members to be covered, and any current insurance information.
• Step 2 — Compare your options. A licensed Florida agent can pull every plan available in your zip code, calculate your exact subsidy, and compare premiums, deductibles, networks, and formularies side by side. This service is free — agents are paid by the carrier.
• Step 3 — Confirm your network. Verify that your preferred doctors, specialists, and hospitals are in-network under any plan you're considering. Network differences between carriers can be significant in Florida.
• Step 4 — Complete enrollment. Your agent can enroll you through HealthCare.gov on your behalf. You'll receive a confirmation from both the marketplace and your chosen carrier.
• Step 5 — Pay your first premium. Coverage does not activate until the carrier receives your first payment. Your agent will walk you through this step.

If You Missed Open Enrollment

Missing the January 15 deadline doesn't necessarily leave you without options. A Special Enrollment Period (SEP) applies if you experience a qualifying life event within the calendar year — including job loss, marriage, divorce, having a baby, moving to a new state, or losing Medicaid eligibility. SEPs give you 60 days from the qualifying event to enroll. See our complete Florida SEP guide for the full list of qualifying events.

Florida ACA Carriers Available in 2026

Following Aetna's exit, Florida's 2026 ACA marketplace carriers include:

• Florida Blue (BCBS of Florida) — Largest carrier in Florida; broad statewide network; generally strong provider access
• Ambetter from Sunshine Health — Competitive premiums; good option for young adults and families seeking lower monthly costs
• Oscar Health — Technology-forward carrier; popular in South Florida and major metro markets
• Molina Healthcare — Strong Silver plan options; focuses on cost-sharing reduction eligible households
• UnitedHealthcare — Broad network; available in select Florida counties
• Cigna — Available in select markets; competitive Gold-tier options

Not every carrier is available in every Florida county. A licensed agent can show you exactly which plans are available at your zip code. You can also explore plan options at FloridaPlanFinder.com.

Common Open Enrollment Mistakes Florida Residents Make

• Waiting until January to enroll. Enrolling after December 15 means February 1 coverage, not January 1 — leaving a gap in coverage that can create out-of-pocket exposure.
• Auto-renewing without comparing. Plan details, premiums, deductibles, and networks change every year. Auto-renewal is convenient but rarely optimal — always compare before defaulting to your current plan.
• Underestimating income. If you underestimate your income to claim a larger subsidy and then earn more, you'll owe the difference at tax time. Use a realistic income estimate.
• Skipping Silver just to save on premiums. Silver plans with CSR can have deductibles far lower than Bronze — for lower-income households, the total cost of care on Silver often beats Bronze despite higher premiums.
• Not verifying your network. Especially after a carrier change (like the Aetna transition), confirm that your doctors accept the new plan before enrolling.
