An equal parenting schedule does not necessarily produce zero child support. Income differences and the allocation of child-related expenses can still require a transfer between households. A reliable calculation begins with accurate financial information and an accurate overnight calendar.
Start with statutory net income
Florida uses the parents’ combined monthly net income and the number of children to determine a basic guideline obligation. Statutory net income subtracts permitted deductions, not every deduction appearing on a paycheck. Qualifying employment-, job-search-, or education-related childcare and child health-insurance costs are addressed under the guidelines, with appropriate credit for direct payments. Uncovered medical, dental, and prescription expenses are included unless separately allocated on a percentage basis. Avoid counting the same expense twice. Fla. Stat. §§ 61.30(2)–(10), 61.13(1)(b) (2026).
Collect recent pay statements, tax returns, insurance premium information, and childcare invoices. Identify bonuses, commissions, self-employment receipts, and changes in working hours. For a business owner, a tax return alone may not explain the cash available for support; business records should allow the parties to examine revenue, expenses, and personal expenditures paid through the business.
How substantial time-sharing changes the calculation
When each parent exercises at least 20% of annual overnights—73 in a 365-day year—the statutory adjustment multiplies basic apportioned support by 1.5, applies the other parent's overnight percentage, and offsets the resulting amounts. Childcare and health-insurance adjustments follow. Fla. Stat. § 61.30(11)(b) (2026).
Equal overnights do not necessarily eliminate a support payment. Where incomes differ, the substantial-time-sharing formula can still produce a transfer between households before childcare, insurance, and other permitted adjustments. A worksheet is only as reliable as the evidence supporting its income, deduction, expense, and overnight entries.
Count holidays, summer weeks, and school breaks carefully. Review the calendar against the schedule actually being exercised. Using an aspirational schedule can distort the calculation and create a later dispute.
When can the court deviate
A variation exceeding 5% requires written findings explaining why guideline support would be unjust or inappropriate. Statutory considerations include extraordinary medical or educational expenses, special needs, seasonal income, and other relevant circumstances. Fla. Stat. § 61.30(1)(a), (11)(a) (2026).
A request to deviate should connect a documented expense or circumstance to a specific proposed amount. Gather invoices and explain whether an expense is ongoing, reimbursable, or already reflected elsewhere. The opposing parent should check for duplicated costs and unsupported assumptions.
Income imputation, earlier support, and termination
Voluntary unemployment or underemployment may support imputation, but the statutory findings and evidence requirements matter; incarceration is not treated as voluntary unemployment. In an initial support determination, the court may award retroactive support within the statutory limit of 24 months before filing and must consider qualifying payments already made. Orders also need appropriate termination and step-down provisions; support does not always end at age 18 in every circumstance. Fla. Stat. §§ 61.30(2)(b)–(c), (17), 61.13(1)(a) (2026).
Review the support order and any worksheet with current financial records and an accurate overnight calendar. Different schedules for different children, fluctuating income, or unusually high or low income may require additional analysis. Do not change payments solely because an informal calculation produces a different result.
What to bring to a consultation
- Orders and worksheets
- income and tax records
- business records where applicable
- actual overnight calendars
- insurance cost breakdowns
- childcare bills
- uncovered healthcare expenses
- and payment history
When to act promptly
Act promptly on served papers or agency notices. A new calculation does not itself modify an existing support order.
