Florida child support: how the guidelines calculate the number

How the Florida Child Support Guidelines Worksheet works, what counts as income, and when courts deviate.

Florida divorce guide

Quick answer

Florida child support is calculated under Florida Statute 61.30 using an income-shares model. Both parents' net monthly incomes are combined, applied to the statutory guideline schedule, and split by income share — then adjusted for overnights with each parent, health insurance, and work-related childcare.

How the guidelines model works

Florida uses an income-shares approach: the law estimates what the parents would have spent on the child if they remained together, then divides that obligation between them in proportion to each parent's share of combined net income. The exact dollar amounts are taken from the statutory schedule in Florida Statute 61.30.

What counts as income

Florida defines gross income broadly. Common categories include the following.

  • Wages, salary, bonuses, commissions, and tips
  • Self-employment net income
  • Disability and workers' compensation benefits
  • Pension and retirement benefits
  • Rental income (net of expenses)
  • Imputed income when a parent is voluntarily unemployed or underemployed

Adjustments to gross income

Florida law allows specific deductions to arrive at net income for the worksheet — including federal and state income taxes, FICA, mandatory union dues, mandatory retirement payments, health insurance premiums (except those covering the child), and court-ordered support for other children actually paid.

Overnights and shared parenting

When a parent has the child for 20% or more of the overnights in a year (73+ nights), Florida applies the gross-up method, which generally reduces the support obligation of the higher-earning parent. The closer the schedule moves toward 50/50, the more the calculation reflects shared expenses.

Health insurance and childcare

Premiums paid for the child's health insurance and work-related childcare costs are added on top of the basic obligation and divided between the parents in proportion to their shares of combined net income. These line items appear on the Guidelines Worksheet.

Frequently asked questions

Can parents agree to a child support amount different from the guideline?
Florida courts will deviate from the guideline amount only when supported by written findings. Parents can request a deviation in their settlement agreement, but the judge must determine the deviation serves the child's best interest.
Is child support taxable income?
Under federal tax law, child support is neither deductible by the paying parent nor taxable to the receiving parent. Florida law does not change this treatment.
How long does child support continue in Florida?
Florida child support generally continues until the child turns 18, or until age 19 if the child is still in high school with a reasonable expectation of graduation. Support for a dependent adult child with disabilities may continue longer under Florida Statute 61.1255.
Can support be modified later?
Yes. Florida allows modification when there is a substantial change in circumstances — typically a 15% or $50 monthly change in the guideline amount (whichever is greater) lasting at least six months.
