Open enrollment is the one time each year when almost anyone can sign up for a health plan, switch plans, or update their coverage, no questions asked. For 2027 coverage, that window runs November 1, 2026 through January 15, 2027 on the federal marketplace, which Florida uses. Miss it and you may be locked out until the following year unless a major life event opens a special window. This guide walks you through the key dates, what a Special Enrollment Period is, and a simple checklist so you walk in prepared instead of scrambling at the deadline.
Open enrollment is a set window each year when you can enroll in a health insurance plan or change the one you have without needing a qualifying reason. Outside of this window, the marketplace is generally closed to new sign ups unless you experience a life event. The window applies to individual and family plans bought through the ACA marketplace or directly; employer group plans run their own annual enrollment period set by the employer.
For states that use the federal marketplace, HealthCare.gov (which Florida uses), open enrollment for 2027 coverage runs on this schedule:
A quick note on why this matters: a rule finalized in 2025 would have shortened this window to end December 15, with no January extension. A federal judge vacated that rule in June 2026, and on August 4, 2026, CMS confirmed that open enrollment on HealthCare.gov will run the traditional November 1 to January 15 schedule for 2027 coverage. HHS has appealed, with oral arguments expected in late October 2026, so it is worth double checking dates closer to enrollment in case anything changes. A handful of state based exchanges set their own dates, so always confirm the current schedule for your state before you rely on it. Employer group plans have their own dates, which your HR department or broker will announce.
Quick tip: Enroll by December 15 if you want coverage to start January 1. You can still enroll through January 15 for a February 1 start, but earlier is better: it gives you time to confirm your doctors are in network and avoids the last minute rush when help is hardest to reach.
Also worth knowing: Subsidy amounts changed for 2026 and carry into the 2027 plan year, the enhanced premium tax credits that lowered costs since 2021 have expired. See why premiums went up this year before you re-shop your plan.
If you miss open enrollment, a Special Enrollment Period, or SEP, may still let you sign up. An SEP is usually a 60 day window that opens after a qualifying life event, including:
In addition, households with income below a certain level can often enroll year round. If you are not sure whether you qualify, it is worth a quick call, because many people assume they are locked out when they actually are not.
Walk in ready with these five things and enrollment takes minutes instead of hours:
The biggest errors people make during open enrollment are auto renewing without checking whether their plan or subsidy changed, underestimating income and owing money at tax time, choosing the lowest premium without checking the deductible and network, or waiting past December 15 and accidentally pushing their coverage start to February instead of January. A few minutes of review, or a free call with a broker, prevents all four.

For 2027 coverage, open enrollment on the federal marketplace (HealthCare.gov, which Florida uses) runs November 1, 2026 through January 15, 2027. Enroll by December 15 for a January 1 coverage start, or enroll by January 15 for a February 1 start. Some state exchanges differ, so confirm your state's dates before the window closes.
You generally cannot buy a marketplace plan until the next window unless you qualify for a Special Enrollment Period triggered by a life event, or your income qualifies you for year round enrollment.
It is a window, usually 60 days, that opens after a qualifying life event such as job loss, marriage, a move, or a new baby, letting you enroll or change plans outside the normal window.
No. Enrolling is free, and working with a licensed broker like Jade Benefits costs you nothing, since brokers are paid by the carrier, not by you.
