No State Has More Riding on ACA Subsidies Than Florida, and They Are Already Gone

Florida has more people enrolled in Affordable Care Act marketplace coverage than any other state, with more than 4.7 million residents holding plans purchased through the exchange. That distinction has turned the expiration of enhanced federal premium subsidies at the end of 2025 into a Florida story more than a national one, with analyses projecting that average premium costs for subsidized Florida enrollees rise by well over 100 percent.

What expired and when

The enhanced premium tax credits originated as a pandemic-era measure in 2021, expanding both the size of subsidies for people already eligible and the income range over which subsidies were available. Congress extended them once, moving the expiration to the start of 2026, and they lapsed on December 31, 2025.

Two distinct changes took effect. For lower-income enrollees, the enhanced credits had reduced or eliminated premiums entirely for benchmark plans; their expiration restores premium obligations that had been zeroed out. For households above four times the federal poverty level, the enhanced credits had removed the eligibility cliff entirely; their expiration restores it, meaning those households lose subsidies outright rather than seeing them reduced.

Nationally, KFF analysis found that the more than 20 million subsidized marketplace enrollees are seeing premium costs rise by an average of 114 percent in 2026. An analysis from the Center for American Progress projected that Floridians receiving enhanced subsidies would face average increases around 132 percent, or roughly 521 dollars annually.

Why Florida is the epicenter

Florida's marketplace enrollment is disproportionate to its population for structural reasons. The state did not expand Medicaid under the ACA, which leaves adults with incomes between the Medicaid eligibility threshold and the poverty line in a coverage gap and pushes many low-income working adults toward marketplace plans that in expansion states would be covered by Medicaid.

The state's employment composition compounds it. Florida's economy is weighted toward tourism, hospitality, agriculture, construction, and small business, sectors where employer-sponsored coverage is less common than in manufacturing or professional services. Self-employment and gig work are also prevalent, and those workers buy individual coverage.

Florida also has a large population of adults aged 55 to 64, too young for Medicare and often retired early or working reduced hours. That group faces the highest premiums in the age-rated individual market and was among the largest beneficiaries of the enhanced subsidy structure that removed the income cliff.

What carriers filed

Insurers writing individual policies in Florida had proposed substantial rate increases for 2026 plans independent of the subsidy question. Fourteen carriers filed double-digit increases, with Blue Cross and Blue Shield of Florida proposing an overall rate change near 27 percent.

Those filings compound with the subsidy expiration. Gross premiums rise, and the subsidy that offset a portion of them shrinks or disappears. An enrollee experiences both changes simultaneously in what they actually pay.

The Florida Office of Insurance Regulation posted the filing information for illustrative purposes but did not separately publicize its availability ahead of the open enrollment period, which drew criticism from consumer advocates who argued enrollees needed advance warning to plan.

The coverage loss projection

Analysis conducted by the Urban Institute and the Commonwealth Fund projected that higher premiums from expiring subsidies would lead roughly 4.8 million Americans to drop coverage. Given Florida's share of national marketplace enrollment, a substantial portion of that figure falls in this state.

Coverage loss does not distribute evenly. The people most likely to drop coverage are those who are relatively healthy and who face the largest percentage increases, which is exactly the adverse selection dynamic that drives up costs for the people who remain. Insurers price subsequent years anticipating a sicker risk pool.

Uncompensated care is where the cost reappears. Uninsured Floridians who need care still receive it through emergency departments, and hospitals absorb those costs and distribute them across paying patients and negotiated commercial rates. Florida's hospital systems, including the large nonprofit networks that operate across the state, carry that burden.

What enrollees can do

Households that saw their premiums jump have options worth evaluating even if none is fully satisfying. Comparing plans across metal tiers is the first step, since the relationship between the benchmark silver plan and the subsidy calculation means bronze and gold plans can produce counterintuitive net costs.

Enrollees whose income estimate changes during the year should update it through the marketplace, since subsidy amounts are calculated on projected income and reconciled at tax filing. Under-reporting income to obtain a larger advance credit produces a tax bill later.

Special enrollment periods allow mid-year plan changes after qualifying life events including job loss, marriage, birth, and moving. Outside those windows, the annual open enrollment period beginning November 1 is the opportunity to change coverage for the following year.

The state and federal policy picture

Restoring the enhanced subsidies requires congressional action, and the issue has been a recurring subject in budget negotiations. Florida's congressional delegation includes members on both sides of the question, and the state's outsized marketplace enrollment gives its representatives a direct constituent interest.

Medicaid expansion remains the state-level policy lever that would address the coverage gap most directly. Florida is among the states that have not expanded, and expansion would move a substantial population out of the marketplace and into Medicaid, changing the arithmetic for both programs.

Separately, Florida's administration of federal benefit programs has drawn scrutiny this week on a different front, with seven Democratic members of the congressional delegation questioning a state plan to procure an artificial intelligence vendor to analyze food assistance eligibility on an accelerated timeline.

How the subsidy formula actually works

Marketplace subsidies are calculated against a benchmark, specifically the second-lowest-cost silver plan available in an enrollee's rating area. The subsidy equals the difference between that benchmark premium and a defined percentage of household income, with the percentage rising as income rises.

That structure produces effects people find counterintuitive. Because the subsidy is pegged to the silver benchmark but can be applied to any metal tier, an enrollee can sometimes obtain a bronze plan for very little or a gold plan for less than silver, depending on how the local premium structure is shaped.

It also means that when benchmark premiums rise, subsidies rise with them for people who remain eligible, partially insulating them from carrier rate increases. The people fully exposed to rate increases are those above the eligibility threshold, who pay the full premium.

The enhanced subsidies changed two parameters: they lowered the percentage of income enrollees were expected to contribute at every level, and they removed the hard cutoff at four times the federal poverty level. Their expiration restored both, which is why the effects fall so differently across income bands.

The rural and small business dimension

Rural Florida counties face a distinct version of this problem. Marketplace competition is thinner outside metropolitan areas, and in counties with fewer participating carriers, benchmark premiums are higher and plan choice is more limited.

Provider networks compound it. A narrow network plan is workable in a metropolitan area with multiple hospital systems and abundant specialists. In a rural county with one hospital, a network that excludes it leaves enrollees traveling substantial distances for covered care.

Small businesses are the other affected group. Florida's economy includes a very large number of small employers, and firms below the threshold that triggers coverage requirements often do not offer insurance, leaving employees in the individual market. Rising individual market costs become a recruitment and retention problem for those employers.

Some small businesses have responded by exploring level-funded and self-insured arrangements, which operate under different regulatory rules than fully insured small group plans. Those options carry risk that a small employer may not be well positioned to absorb.

What people do when coverage becomes unaffordable

Households facing an unaffordable premium have a limited set of realistic options, and the choices they make have consequences that show up in the health system later. Dropping to a bronze plan with a high deductible preserves catastrophic protection while making routine care effectively out of pocket.

Some enrollees turn to products that sit outside ACA regulation, including short-term limited duration plans and health care sharing ministries. Those arrangements are generally cheaper and generally provide substantially less protection, frequently excluding pre-existing conditions or capping benefits in ways ACA plans cannot.

Others go without coverage entirely and manage acute needs through emergency departments and urgent care. That pattern defers rather than eliminates cost, and it shifts care from lower-cost preventive settings to the most expensive point in the system.

The clinical consequence appears over years rather than months. Chronic conditions including diabetes, hypertension, and cardiovascular disease are manageable with consistent care and expensive when they are not, and coverage interruptions in a population with those conditions produce measurable downstream costs.

What's next

Open enrollment for 2027 coverage begins November 1. Between now and then, whether Congress acts on the subsidy question is the single variable that would most change the picture for Florida enrollees.

Enrollment data for 2026 will show how many Floridians actually dropped coverage rather than how many were projected to. Those figures become available through the Centers for Medicare and Medicaid Services and will be the clearest measure of the expiration's effect.

Florida residents seeking help with marketplace enrollment can work with navigators and certified application counselors, who provide free assistance and are available through community organizations across the state. That assistance is particularly valuable given how much the plan comparison math changed this year.

Floridians who dropped coverage this year and later experience a qualifying life event can re-enroll through a special enrollment period rather than waiting for November, which is worth knowing for anyone whose circumstances change mid-year.
