Key takeaways

• Florida follows the Income shares model for presumptive child support.
• Income is generally measured using net income, then allocated under Fla. Stat. § 61.30.
• Guideline amounts are presumptive, not automatic — courts may deviate when the facts justify it.
• Support generally ends at 18, or 19 if still in high school with a reasonable expectation of graduation before 19; longer support may apply for dependent adult children with disabilities.
• Either parent can seek modification when substantial change in circumstances; a 15% or $50 difference (whichever is greater) between existing and guidelines support creates a presumption for modification..
• Read the companion guide: Florida alimony / alimony.

Statutory framework and guideline model

Florida's child support system is built around Fla. Stat. § 61.30. Under the income shares, Florida combines net monthly incomes, applies the statutory guidelines schedules (including grossed-up gross-to-net computations), and allocates the obligation by income share. Substantial overnight timesharing triggers a gross-up calculation; childcare and health insurance are add-ons.

Federal law requires every state to maintain presumptive guidelines and to review them at least every four years (42 U.S.C. § 667). Guideline schedules and self-support reserves have been periodically updated by the legislature; always use the current § 61.30 chart.

How child support is calculated in Florida

1. Identify each parent's guideline income using net income as defined in Fla. Stat. § 61.30 and the accompanying worksheets or administrative rules.
2. Apply the income shares — whether that means a combined-income schedule, an obligor percentage table, or a Melson-style self-support reserve plus primary obligation.
3. Allocate add-ons such as health insurance premiums, unreimbursed medical expenses, and work-related child care according to Florida practice.
4. Consider parenting time adjustments where the guidelines or case law authorize a credit or shared-custody formula.
5. Test for deviation if a strict guideline result would be unjust or inappropriate on the record.

Online calculators can illustrate ranges, but only the controlling statute, guidelines, and court findings produce an enforceable order.

Deviation from the guidelines

Deviation of more than 5% requires written findings. Common themes include seasonal income, special needs, and total family circumstances under § 61.30(11).

When a court departs from the presumptive amount, Florida practice generally requires findings that explain why the guideline figure is unjust or inappropriate and what amount better serves the child's needs. Those findings matter on appeal and in later modification proceedings.

Modification of child support

Substantial change in circumstances; a 15% or $50 difference (whichever is greater) between existing and guidelines support creates a presumption for modification.

A parent seeking a change typically must show that circumstances after the prior order make the existing award inequitable. Common triggers include job loss, substantial income changes, a new parenting-time schedule, emancipation of a child, or extraordinary medical needs. Retroactivity and temporary relief rules are statute-specific — check Fla. Stat. § 61.30 and local family-division procedures.

Enforcement in Florida

Clerks and the Department of Revenue IV-D program use income deduction orders, intercepts, contempt, and license suspension.

Interstate cases often implicate UIFSA. Income withholding, contempt, license suspension, and tax-refund intercept remain core tools nationwide, but the Florida child support agency and clerk of court procedures control day-to-day collection.

When child support ends

In Florida, Support generally ends at 18, or 19 if still in high school with a reasonable expectation of graduation before 19; longer support may apply for dependent adult children with disabilities. Orders may extend for disability, secondary education, or other statutory grounds where the statute allows. Always read the judgment language — agreed orders sometimes set a different end date or require a notice of emancipation.
