Covering a family in Florida starts with a single ACA marketplace application at healthcare.gov. One household enrollment calculates your subsidy based on total family size and income, then covers every member you include. But families also have options beyond the marketplace — including Florida KidCare for children — that can significantly reduce total household costs when used strategically. This guide covers everything Florida families need to know about enrollment, subsidies, children's coverage, and choosing the right plan.
One Application Covers the Whole Household
The ACA marketplace treats your family as a single unit. At healthcare.gov, you complete one application for yourself, your spouse, and any dependents you claim on your federal tax return. The Advanced Premium Tax Credit (APTC) is calculated on the full household's size and projected annual income, which typically produces a larger subsidy at higher absolute income levels because FPL thresholds scale with family size.
| Household Size | 100% FPL (2026) | 250% FPL | 400% FPL |
|---|---|---|---|
| 2 people | $21,600 | $54,000 | $86,400 |
| 3 people | $27,240 | $68,100 | $108,960 |
| 4 people | $33,240 | $83,100 | $132,960 |
| 5 people | $39,240 | $98,100 | $156,960 |
Florida KidCare: Separate Coverage for Children
Florida KidCare is the state's Children's Health Insurance Program (CHIP), covering children under 19 in households with income up to 200% of the Federal Poverty Level. For a family of four in 2026, that threshold is $66,480. KidCare operates independently from the ACA marketplace — you can enroll year-round, not just during open enrollment.
KidCare premiums are very low: typically $20 to $35 per child per month, and some families pay nothing depending on income. The coverage is comprehensive, including doctor visits, hospitalizations, prescriptions, dental, and vision. Apply at floridakidcare.org.
The Split-Coverage Strategy
For families in the 150 to 200% FPL range, enrolling children on KidCare and adults on a Silver ACA marketplace plan often produces lower total household costs than a single family marketplace plan. Here is why:
- KidCare premiums for two children: approximately $40 to $70/month total
- Adults-only Silver plan with CSR: lower premium than a full family plan, with enhanced benefits
- Combined cost is frequently $100 to $200 less per month than a single family plan
Important: Even though children are enrolled separately on KidCare, you still include them on your healthcare.gov application for household size purposes. This ensures your subsidy calculation reflects the full household. You then decline marketplace coverage for the children and enroll them through KidCare instead.
Silver Plans with CSR: The Right Choice for Most Families
For families with income between 100% and 250% FPL, Silver plans with Cost-Sharing Reductions are almost always the best value. CSR restructures the plan's deductible, copays, and out-of-pocket maximum based on your income tier — without increasing your premium. At 100 to 150% FPL, a family Silver plan with full CSR can carry a combined deductible as low as $300 to $500, compared to Bronze family plan deductibles of $10,000 to $16,000.
This is not a marginal difference. For a family where children see doctors regularly, need prescriptions, or may need emergency care, the CSR benefit transforms a Silver plan from adequate to genuinely protective. Do not choose a Bronze plan solely for its lower premium if your family qualifies for CSR.
Embedded vs. Aggregate Deductibles
When comparing family plans, check whether the deductible is embedded or aggregate. An embedded deductible gives each family member their own individual deductible — once any one person hits it, that person's costs are covered even if the family total has not been met. An aggregate deductible pools all family spending into one total that must be met before anyone's costs are covered.
Aggregate deductibles can be harsh for families where one member generates most of the medical costs early in the year. Most Silver and Gold plans use embedded deductibles. Check the Summary of Benefits and Coverage document for any plan you are considering.
Adding a Newborn or Adopted Child
Having or adopting a baby is a qualifying life event that opens a 60-day Special Enrollment Period. You can add the new child to your existing marketplace plan or switch to a different plan that better fits your larger family. The 60-day clock starts on the date of birth or adoption placement. Update your healthcare.gov application promptly — your household size increase will also recalculate your subsidy, potentially increasing your APTC.
What Happens When a Child Turns 26
Under the ACA, children can stay on a parent's marketplace plan until they turn 26. After that, aging off the plan is a qualifying life event, and the child has 60 days to enroll in their own marketplace coverage. If the child is also losing employer coverage (because the parent's employer plan covered them), both events can trigger an SEP.
