Open enrollment is the annual window during which Florida residents can enroll in ACA marketplace health insurance, switch plans, or update coverage without needing a qualifying life event. Miss it, and your options for getting insured are limited until the next open enrollment period — or unless a qualifying event such as a job loss or move triggers a Special Enrollment Period.
This guide covers the exact 2026–2027 open enrollment dates, the critical deadlines within that window, how enrollment works on healthcare.gov, and what you need to have ready before you start.
| Action | Deadline | Coverage Start Date |
|---|---|---|
| Enroll for January 1 coverage | December 15, 2026 | January 1, 2027 |
| Enroll for February 1 coverage | January 15, 2027 | February 1, 2027 |
| Open enrollment window closes | January 15, 2027 | — |
The window opens November 1, 2026. You have 76 days to shop and enroll. But there is an important split within that window: December 15 is the last day to enroll with a January 1 effective date. If you complete your enrollment on December 16 or later, your coverage will not start until February 1 — leaving you without ACA insurance for the entire month of January.
Florida is one of the majority of states that relies on the federally-facilitated marketplace rather than operating its own state exchange. Every aspect of Florida ACA enrollment — creating an account, submitting an application, entering your household information and income, comparing plans, selecting a plan, and confirming enrollment — happens at healthcare.gov.
There is no separate Florida health insurance exchange, Florida marketplace portal, or state government enrollment site for ACA plans. If you see a third-party site claiming to be the Florida marketplace, be cautious — the official federal site is healthcare.gov, and enrollment through that site is required to receive premium subsidies (APTC).
One benefit of the federal marketplace for Florida residents: the same account you created in previous years still exists. You do not need to start from scratch — log in with your existing credentials and update your information for the new plan year.
Having the right information ready before logging into healthcare.gov will make the enrollment process significantly faster and reduce the chance of errors that delay your application.
Step 1 — Create or log into your account. Visit healthcare.gov and create an account if you don't have one. Returning users log in with their existing username and password. Your previous application information may pre-populate, but review everything carefully for the new plan year.
Step 2 — Complete or update your application. The application collects your household size, income estimate, employment status, and citizenship/immigration status for everyone in your household. Accuracy here matters: underestimating income could result in owing money back at tax time; overestimating means you'll receive a smaller-than-necessary subsidy throughout the year.
Step 3 — Review your eligibility results. Healthcare.gov will calculate your estimated APTC (premium tax credit) and let you know if any household members are eligible for Medicaid or CHIP instead of marketplace coverage. Florida Medicaid eligibility for children and pregnant women may redirect some family members to Medicaid automatically.
Step 4 — Compare plans. You will see all ACA-compliant plans available in your Florida county, organized by tier (Bronze, Silver, Gold, Platinum, Catastrophic). The site shows your estimated after-subsidy monthly premium. Pay close attention to deductibles, copays, and out-of-pocket maximums — not just premiums. For incomes between 100% and 250% FPL, Silver plans with Cost-Sharing Reductions may offer dramatically better value than they appear at first glance.
Step 5 — Select your plan. Once you choose a plan, confirm your selection. Healthcare.gov will send you a confirmation and provide information about contacting your new carrier.
Step 6 — Pay your first premium. This step is critical and happens outside healthcare.gov. Your new carrier will send a bill (or make one available in your online account with the carrier). You must pay the first month's premium before your coverage activates. A completed application with a plan selection does not mean you are insured until that first payment is made and processed.
After completing enrollment and paying your first premium, you should receive a welcome packet from your insurance carrier, typically within 7–14 days. This packet includes your member ID number, which you can use to access care even before your physical insurance card arrives.
Insurance cards typically arrive within 2–3 weeks after enrollment. If you need care before your card arrives, contact your carrier directly to get your member ID and confirm your effective date. Most carriers also have online portals or apps where your insurance card is available digitally within days of payment.
Important: if you receive premium tax credits (APTC) and your income, household size, or other circumstances change during the year, report those changes to healthcare.gov promptly. Changes can affect your subsidy amount and, if not reported, can result in a larger-than-expected balance due when you file your taxes.

When is open enrollment for health insurance in Florida in 2026?
Florida's ACA open enrollment for 2027 plan year coverage runs November 1, 2026 through January 15, 2027. Enroll by December 15, 2026 for coverage starting January 1, 2027. Enroll by January 15, 2027 for coverage starting February 1, 2027.
Does Florida have its own health insurance exchange?
No. Florida uses the federal marketplace at healthcare.gov. There is no separate state exchange or Florida-specific portal. All ACA plan shopping, enrollment, and subsidy applications happen at healthcare.gov.
What happens if I miss open enrollment in Florida?
If you miss the January 15, 2027 deadline without a qualifying life event, you cannot enroll in a marketplace plan until the next open enrollment period (November 2027). You may be able to purchase a short-term health plan as a stopgap, but these plans are not ACA-compliant and do not qualify for subsidies. If you experience a qualifying life event — such as losing job-based coverage, moving, getting married, or having a child — you can enroll through a Special Enrollment Period.
Do I have to re-enroll in my ACA plan every year during open enrollment?
Technically no — your plan will auto-renew if you take no action. However, auto-renewal is almost never the optimal choice. Premiums, plan structures, carrier networks, and subsidy amounts all change year to year. Taking 20 minutes to compare plans during open enrollment can save hundreds or even thousands of dollars annually.
A licensed Florida health insurance agent can compare every plan available in your county, calculate your exact subsidy, and help you enroll — at no cost to you. Agents are paid by carriers, not by you.
