Top 5 Mistakes to Avoid When Enrolling in ACA Coverage in Florida

Top 5 Mistakes to Avoid When Enrolling in ACA Coverage in Florida

Every year, Floridians lose money or go without coverage because of avoidable enrollment errors. Most of them come down to dates, income, and assumptions about automatic renewal. With the 2027 Open Enrollment Period opening November 1, 2026, here are the five mistakes to watch for.

Mistake 1: Letting Your Plan Auto-Renew Without Checking It

If you already have Marketplace coverage, HealthCare.gov will automatically re-enroll you in a plan for next year to help avoid a gap in coverage. That is convenient, but the matched plan may change in price, benefits, or insurer. Log in, update your expected income and household information, and compare plans before you accept the default.

Mistake 2: Missing the Enrollment Deadlines

Deadlines are the most common and most costly error. Per HealthCare.gov, the key dates are:

After January 15, you can generally enroll only if you qualify for a Special Enrollment Period. Note that December 15 is not the end of Open Enrollment; it is the deadline for a January 1 start.

Mistake 3: Estimating Your Income Poorly

Your premium tax credit is based on your expected income for the coverage year. If you underestimate and take advance credits, you may owe money at tax time. Beginning with the 2026 tax year, the caps on repaying excess advance credits were removed under H.R. 1, so you could be required to repay the full excess, according to HealthInsurance.org. The enhanced subsidies that applied from 2021 through 2025 expired at the end of 2025 and, as of early October 2026, have not been reinstated, so staying under 400% of the Federal Poverty Level matters.

Mistake 4: Forgetting to Report Changes During the Year

A raise, a new job, a new household member, or an offer of other coverage can all change what you qualify for. HealthCare.gov advises updating your application as soon as possible. If you do not report a change that lowers your eligibility, you will have to pay back the difference when you file your federal tax return.

Mistake 5: Choosing a Plan Based on Premium Alone

The lowest monthly premium is not always the lowest total cost. Before you pick a plan, look at the following:

• Deductible and out-of-pocket maximum: what you pay before and beyond the plan’s coverage.
• Provider network: confirm your doctors and hospitals are in network.
• Prescription formulary: check that your medications are covered and at what tier.
• Metal level: Bronze, Silver, and Gold plans trade premiums against cost-sharing.

Quick Checklist Before You Click Enroll

• Update your household size and expected income for 2027.
• Confirm your doctors, hospitals, and prescriptions against each plan you are considering.
• Pay your first premium on time, since coverage does not start until it is paid, as noted by HealthCare.gov.
• Save your confirmation and watch for any request to upload documents that verify your income.
