ACA Open Enrollment for 2027 in Florida: The Two Deadlines That Matter, and Why Auto-Renewing Costs You

Data current: August 24, 2026 · Florida · 13 min read

Every year I tell Marketplace clients the same thing in August, and every year about a third of them ignore it until December. This year I am going to be blunter, because the margin for error is genuinely smaller than it has ever been.

For 2027 coverage, two things changed and a third nearly did. The enhanced subsidies that made premiums affordable are gone. One of the carriers Floridians rely on is leaving the state’s Marketplace entirely. And the shorter enrollment window that was supposed to arrive this year did not — a federal court blocked it, so January 15 is still the last day to enroll. That last one is good news, but it does not rescue the habit of letting your plan auto-renew. This is the year that habit gets expensive.

I am Vivian Soto, an independent bilingual insurance agent at VS Healthcare Solutions in Orlando. This is the guide I give my own clients: what actually changed, what your premium is likely to look like, what documents to gather before November 1, and the order to do things in. Nothing here requires you to be an expert. It requires you to start early.

What changed for 2027, in plain terms

Three separate changes landed on the same plan year. It helps to keep them apart in your head, because each one calls for a different response.

The shorter window did not survive. A 2025 federal rule would have closed Open Enrollment on December 15 and removed the January buffer. A federal court blocked large parts of that rule during 2026, and HealthCare.gov now lists the window for 2027 coverage as November 1 through January 15. So two dates matter, not one. Enroll by December 15 and your coverage is in force on January 1. Enroll between December 16 and January 15 and it starts February 1 — which leaves you uninsured for January. If you expect to need care in January, a surgery, a refill or a specialist visit, December 15 is your real deadline. You will still find the December 15 end date on other sites and in older guides, including an earlier version of this one; it was accurate when it was written.

Year-round enrollment for low-income households ended. The monthly Special Enrollment Period that let people at or below 150% of the federal poverty level sign up any time of year is gone. If that is how you or a family member enrolled before, that door is closed. Open Enrollment is now the door.

Life-event verification is on hold. The same 2025 rule would have required your documents to be checked before a Special Enrollment Period turned your coverage on. A court stayed that requirement for federally-run Marketplaces, and Florida is one, so it is not in force for this cycle. The Marketplace can still ask for documents after you enroll, and it can still end a life-event enrollment if you never send them — so send them the same week, not eventually. I wrote the Spanish-language walkthrough of these rule changes in my guide to the new 2027 ACA enrollment rules.

Why auto-renewal is the expensive default this year

If you do nothing, the Marketplace will generally roll you into a plan for 2027 — either your current plan or, if it no longer exists, something it considers comparable. That sounds like a safety net, and in a stable year it mostly is. This is not a stable year.

Auto-renewal carries your plan forward. It does not re-check whether that plan still fits. Three things go stale quietly:

1. Your subsidy is calculated from old income data. Your premium tax credit is based on the income estimate on file. If your income changed in 2026 and you never updated it, you are either paying more than you should all year, or building a bill you will owe back at tax time.
2. Your network may have changed. Carriers adjust their Florida provider networks every year. Auto-renewal will not warn you that your pediatrician or your specialist dropped out.
3. Your drugs may have moved tiers. Same formulary mechanics as any plan year — the medication stays covered, but at a different price.

The honest framing is this: auto-renewal is a decision, not the absence of one. Making it on purpose after twenty minutes of checking is fine. Making it by forgetting is where the money goes.

If you are a Cigna member, you have a hard deadline

On April 30, 2026, Cigna announced it is leaving the individual ACA Marketplace in 2027 across eleven states, Florida among them. About 369,000 members are affected. Those plans end December 31, 2026 — there is no extension and no version of doing nothing that keeps your current plan.

The Marketplace may auto-match you to another insurer so you are not uninsured on January 1. That is a floor, not a recommendation. An automatic match optimizes for continuity of coverage, not continuity of your doctors. If keeping your primary care physician matters to you, you have to choose the plan yourself. I covered the details in what Cigna's exit means for Florida members.

What your premium is actually likely to look like

This is the part people most want a straight answer on, so here are the numbers rather than adjectives.

Florida enrollment has already responded: from about 4.74 million down to roughly 4.47 million. I walked through the full arithmetic in my post on the 2026 subsidy cliff and what Florida families now pay.

Two things are worth saying against the gloom. First, subsidies did not disappear — the enhanced ones did, and the original ACA tax credits remain. Many households still qualify for meaningful help. Second, because every carrier repriced, the plan that was cheapest for you last year very often is not the cheapest this year. That is precisely why re-shopping pays this cycle in a way it did not in quiet years.

The documents to have ready before November 1

Almost every delayed application I deal with comes down to a document nobody could find. With verification now happening before coverage starts, this matters more than it used to. Gather these in October:

• Income documentation for everyone in the household who works — recent pay stubs, and your most recent tax return. If you are self-employed, a profit-and-loss estimate for 2027.
• Social Security numbers and dates of birth for everyone applying.
• Immigration or residency documents for any household member who needs them.
• Your current plan details — member ID card and, if you have it, the letter your carrier sent about 2027.
• Your medication list, with exact names and dosages.
• Your must-keep providers — every doctor and hospital you are not willing to lose.

If you are self-employed, your income estimate is the single highest-leverage number in the whole application, because it sets your subsidy. My guide for self-employed Floridians goes through how to estimate it without over- or under-shooting.

Your six-step plan for the 2027 window

The mistakes I see every November

Shopping on the monthly premium alone. A $40-a-month plan with a $7,000 deductible and a narrow network is not cheaper than a $110 plan that covers your doctor, if you use your insurance at all.

Guessing at income. Underestimate and you owe credits back at tax time; overestimate and you overpay all year. Neither is a rounding error at these premium levels.

Assuming last year's plan is still the good deal. Every carrier repriced for 2027. Loyalty is not rewarded here; it is just not re-checked.

Hearing “January 15” and relaxing. The extra month is real, but it buys a February start, not a January one. People who use it to procrastinate end up paying a full month of medical bills out of pocket. If your application snags on a verification, the days you left yourself are the only thing that saves you.

Frequently asked questions about 2027 ACA enrollment

When is Open Enrollment for 2027 coverage?

November 1, 2026 through January 15, 2027, on HealthCare.gov. Enroll by December 15 and your coverage begins January 1, 2027; enroll between December 16 and January 15 and it begins February 1. A 2025 federal rule would have ended the window on December 15, but a court blocked it, so the January 15 end date stands.

What happens if I miss December 15?

You have not missed Open Enrollment — you have missed January 1. You can still enroll through January 15, and your coverage begins February 1, which leaves you uninsured for the month of January. After January 15 you need a Special Enrollment Period through a life event such as marriage, a birth, a move, or losing job-based coverage.

Will my premium go up for 2027?

Most likely, yes. The enhanced premium tax credits expired December 31, 2025, and benchmark premiums rose roughly 21.7% nationally and about 30% in Florida. How much you personally pay depends on your income, your county and the plan you pick, which is exactly why re-shopping matters this year.

I have a Cigna Marketplace plan. What do I do?

Your plan ends December 31, 2026, because Cigna is leaving Florida's individual Marketplace for 2027. You need to choose a new plan during Open Enrollment. The Marketplace may auto-match you to another insurer, but that match is not built around keeping your doctors, so choose actively.

Do subsidies still exist at all?

Yes. The enhanced subsidies from recent years expired, but the original ACA premium tax credits remain in place. Many Florida households still qualify for substantial help. Do not assume you are ineligible without running the numbers for your actual 2027 income.

Can I still enroll any time if my income is low?

No. The monthly Special Enrollment Period for households at or below 150% of the federal poverty level has ended. If that is how you enrolled previously, Open Enrollment between November 1 and January 15 is now your window.

What if I do nothing at all?

You will usually be auto-renewed into your current plan, or matched to a similar one if yours is discontinued. You keep coverage, but with 2027 pricing, a possibly stale income estimate, and no check on whether your doctors and prescriptions are still covered.

Does working with an agent cost me anything?

No. Independent agents are paid by the carriers, and those commissions are regulated, so your premium is the same whether you enroll on your own or with help. Comparing plans and checking your subsidy costs you nothing.

Why working with a Florida agent matters this year

The work is unglamorous and it is where the savings hide: I take your real income estimate, your actual prescriptions and your must-keep doctors, and run them against every plan available in your county — then compare on annual cost, not monthly premium. Orange, Osceola and Seminole counties do not always offer the same plans or the same networks, so a neighbor's answer is not your answer.

I am licensed in Florida, I work with more than forty carriers, and my services cost you nothing. If the right answer is that your current plan is still the best fit, that is what I will tell you — and you will know it rather than assume it.

If someone in your household is turning 65 this year, the Marketplace question and the Medicare question interact, and the timing is easy to get wrong. My Medicare AEP 2027 prep guide covers that side of the calendar.
