Florida child support is calculated using the Income Shares Model under Fla. Stat. § 61.30, which combines both parents' net monthly incomes and allocates child-rearing costs proportionally based on each parent's share of total income. For one child with combined parental income of $6,000 per month, the guideline amount is $1,121; for two children at the same income level, the amount increases to $1,737. Florida judges have limited discretion and can typically deviate only 5% from guideline calculations without specific justification.

How Florida Calculates Child Support Using the Income Shares Model
Florida determines child support obligations by combining both parents' net monthly incomes and applying a statutory schedule that reflects what intact families typically spend on children at each income level. The calculation under Fla. Stat. § 61.30 ensures children receive the same proportion of parental income they would have received if the family had remained together, with each parent contributing based on their percentage of combined earnings.
Step 1: Calculate Each Parent's Net Monthly Income
Net income is gross income minus allowable deductions. Under Fla. Stat. § 61.30(3), allowable deductions include federal, state, and local income taxes (adjusted for actual filing status), FICA or self-employment tax, court-ordered spousal support from a previous marriage, and mandatory union dues or retirement contributions. Gross income encompasses all sources including wages, bonuses, commissions, business income, disability benefits, workers' compensation, unemployment benefits, pensions, social security, and rental income.
Step 2: Determine Combined Net Income
Add both parents' net monthly incomes together to obtain the combined net income figure. This combined amount is then matched against Florida's child support guidelines chart, which specifies the presumptive monthly child support obligation based on combined income and number of children. For example, combined net income of $3,000 per month yields a guideline amount of $644 for one child and $1,001 for two children.
Step 3: Calculate Each Parent's Proportional Share
Divide each parent's net income by the combined net income to determine their percentage share of the child support obligation. If Parent A earns $4,000 net monthly and Parent B earns $2,000 net monthly (combined $6,000), Parent A is responsible for 67% of the total obligation while Parent B covers 33%. The parent with fewer overnights typically pays their share to the parent with primary physical custody.

The following table shows Florida's statutory guideline amounts for combined net monthly income levels under Fla. Stat. § 61.30(6). These figures represent the total monthly child support obligation before allocation between parents.
| Combined Monthly Net Income | 1 Child | 2 Children | 3 Children | 4 Children |
|---|---|---|---|---|
| $1,500 | $329 | $511 | $594 | $667 |
| $3,000 | $644 | $1,001 | $1,163 | $1,298 |
| $4,500 | $884 | $1,371 | $1,604 | $1,791 |
| $6,000 | $1,121 | $1,737 | $2,055 | $2,307 |
| $8,000 | $1,386 | $2,136 | $2,545 | $2,872 |
| $10,000 | $1,617 | $2,495 | $2,994 | $3,393 |
Time-Sharing Adjustments: How Overnight Custody Affects Child Support
Florida applies a time-sharing adjustment to child support calculations when each parent has substantial overnight custody, defined as 73 or more overnights per year (20% of annual overnights). This adjustment recognizes that parents with significant parenting time incur direct child-rearing expenses during their custody periods, and the formula accounts for this overlap in financial responsibility.
How the Adjustment Works
When the time-sharing threshold is met, Florida uses a more complex formula that factors in both parents' overnights. The paying parent's obligation decreases as their overnight percentage increases because they directly cover more of the child's daily expenses (food, utilities, activities) during their parenting time. A parent with 182 overnights (50% time-sharing) will have a significantly lower support obligation than a parent with only 73 overnights (20% time-sharing), assuming identical incomes.
Standard vs. Extended Time-Sharing Calculations
Under standard time-sharing (one parent has fewer than 73 overnights), Florida uses the basic guideline amount without adjustment. Under extended time-sharing (both parents have 73+ overnights), the formula applies an adjustment multiplier that reduces the total obligation and reallocates shares based on actual parenting time. Courts now calculate child support according to the actual parenting pattern as currently exercised by both parents.
Additional Costs Added to Florida Child Support: Healthcare and Childcare
Florida requires that certain expenses be added to the basic child support obligation and divided proportionally between parents based on their income shares. These add-on expenses under Fla. Stat. § 61.30(7) include health insurance premiums, uncovered medical expenses, and work-related childcare costs.
Health Insurance Costs
Health, dental, and prescription insurance premiums for the children are added to the basic support obligation and allocated between parents proportionally. If Parent A pays $300 monthly for the children's health insurance and has 67% of combined income, Parent B would reimburse Parent A for 33% of that cost ($99 monthly) in addition to their base support payment. Any noncovered medical, dental, and prescription medication expenses are also divided proportionally unless the court orders a different arrangement.
Childcare Expenses
Work-related childcare costs incurred due to employment, job search, or education leading to employment are added to the basic obligation after a 25% reduction. This 25% reduction accounts for federal childcare tax credits that parents may claim. For example, if monthly daycare costs $1,000, the amount added to the child support calculation is $750 (reduced by 25%). Childcare costs cannot exceed the amount required to provide quality care from a licensed source.
When Florida Courts Impute Income to Unemployed or Underemployed Parents
Florida courts impute income to parents who are voluntarily unemployed or underemployed under Fla. Stat. § 61.30(2)(b), meaning the court assigns an income level for child support calculations even when a parent claims little or no actual earnings. This prevents parents from artificially reducing support obligations by choosing not to work or by taking lower-paying jobs than their qualifications warrant.
Voluntary Unemployment Standard
The court must first determine that unemployment or underemployment is voluntary rather than involuntary due to physical or mental incapacity or circumstances beyond the parent's control. Voluntary unemployment occurs when a person deliberately terminates employment without good cause or acts in a way that results in termination. A parent who resigns and chooses not to pursue other employment is considered voluntarily unemployed.
Calculating Imputed Income Amount
Florida courts determine imputed income based on the parent's recent work history, occupational qualifications, and prevailing earnings in the community. The court cannot use income records more than 5 years old and cannot impute income at a level the parent has never earned unless they recently obtained a degree, license, or certification qualifying them for higher earnings. When no earnings history exists, courts may impute income based on a 40-hour workweek at Florida's minimum wage ($13.00 per hour in 2026, or approximately $2,253 monthly gross).
Incarceration Exception
Except for parents incarcerated due to willful nonpayment of child support or offenses against the child or custodial parent, incarceration cannot be treated as voluntary unemployment when establishing or modifying support orders. This exception recognizes that incarcerated individuals cannot work through their own choice.
How to Modify Child Support in Florida
Florida allows child support modification when a substantial change in circumstances would result in a significant change to the support amount. Under Fla. Stat. § 61.30(1)(a), the standard for "substantial change" depends on how recently the order was established or last modified, with different percentage thresholds applying based on the age of the existing order.
Modification Thresholds by Order Age
For orders issued, reviewed, or modified within the past 3 years, a substantial change means the recalculation would change the support amount by at least 15% but not less than $50. For orders more than 3 years old, the threshold drops to at least 10% but not less than $25. The change must also be permanent (typically lasting more than one year) and involuntary rather than self-created.
| Order Age | Required Change | Minimum Dollar Amount |
|---|---|---|
| Less than 3 years | 15% or more | $50 minimum |
| More than 3 years | 10% or more | $25 minimum |
Common Grounds for Modification
Florida courts grant modifications for job loss or significant income changes, increased cost of living, changes in parenting time arrangements, and changes in the children's medical or educational needs. Changes in health insurance costs or childcare expenses can also qualify as substantial changes. The parent seeking modification bears the burden of proving the change meets statutory requirements by a preponderance of the evidence (more likely than not).
Filing for Modification
Either parent can request the Florida Department of Revenue Child Support Program to review their order at no cost, or file a petition directly in circuit court. The petition must include a current financial affidavit and specify the changed circumstances. If both parents agree to a modification, they can submit a stipulated agreement for court approval, which simplifies the process significantly.
When Child Support Ends in Florida
Under Fla. Stat. § 61.13, Florida child support terminates when the child turns 18 years old. If the child is still in high school at age 18 and is reasonably expected to graduate before turning 19, support continues until high school graduation or age 19, whichever occurs first. The maximum age for child support in Florida is 19 years under any circumstance.
Exceptions to Standard Termination
Child support may end before age 18 if the child becomes emancipated through marriage, military enlistment (minimum age 17 with parental consent), or achieving financial independence through other means. A child must be at least 16 years old to petition for emancipation in Florida. Support may continue indefinitely for children with mental or physical incapacities that render them dependent, provided the incapacity began before the child reached age 18.
No Automatic College Support
Unlike some states, Florida law does not require parents to pay child support for adult children attending college. Courts cannot order parents to pay college expenses unless the parents previously agreed to such support in a written agreement. However, parents are free to voluntarily agree to continue support through college, and courts will enforce such agreements if properly documented.
Back Support (Arrears) Never Expires
Unpaid child support (arrears) remains enforceable indefinitely regardless of the child's age. Florida has no statute of limitations for collecting child support arrears, so a parent who owes back support from years ago can still face enforcement actions including wage garnishment, license suspension, and contempt proceedings until the full amount is paid.
Florida Child Support Enforcement: Consequences of Nonpayment
Florida employs aggressive enforcement measures against parents who fail to pay court-ordered child support. The Florida Department of Revenue and circuit courts have numerous tools available under Fla. Stat. § 61.13016 to compel compliance, with consequences ranging from wage garnishment to incarceration for willful nonpayment.
Enforcement Timeline
Enforcement actions begin quickly in Florida. When payment remains unpaid for 15 days, the Clerk's Office may issue a Notice of Delinquency. If the delinquency is not resolved within 20 days of the notice, the court enters a formal judgment against the non-paying parent, which can attach to property and damage credit.
Enforcement Methods Available
Florida's enforcement arsenal includes:
- Wage garnishment (up to 65% of disposable income for arrears)
- Income deduction orders (automatic paycheck withholding)
- Driver's license suspension (can begin after just 15 days of delinquency)
- Professional and recreational license suspension
- Bank account seizure and levies
- Property liens preventing sale or refinancing
- State and federal tax refund interception
- Passport denial for arrears exceeding $2,500
- Credit bureau reporting
- Contempt of court (fines and incarceration)
Contempt and Incarceration
Parents can be held in civil contempt for willful nonpayment, which may result in jail time. For contempt to apply, the court must find that the parent has the ability to pay but is willfully refusing to do so. This protects parents who genuinely cannot afford their obligations while targeting those who choose not to pay despite having means. Child support obligations survive bankruptcy and cannot be discharged.
How to File for Child Support in Florida
Parents can establish child support through the Florida Department of Revenue Child Support Program or by filing directly in circuit court. The DOR provides services at no cost for parents seeking to establish, enforce, or modify support orders. Filing directly in court provides more control but requires paying filing fees and potentially attorney costs.
Filing Fees and Costs
Florida circuit court filing fees for dissolution of marriage (which includes child support) range from $408 to $418 depending on the county. The State Disbursement Unit charges a 4% depository fee on all payments ($1.00 minimum, $5.25 maximum per payment), unless the case is enforced through the Department of Revenue. Fee waivers are available for parents who demonstrate financial hardship using Form 12.902(a).
Required Documents
Every petition for child support must include a financial affidavit showing income, allowable deductions, and net income calculated under Fla. Stat. § 61.30. Parents must also complete the Child Support Guidelines Worksheet (Form 12.902(e)), which walks through the calculation step by step. If seeking an amount different from the guidelines, a Motion to Deviate (Form 12.943) explaining the reasons must also be filed.
Frequently Asked Questions About Florida Child Support
How much is child support for one child in Florida?
Child support for one child in Florida depends on combined parental net income under Fla. Stat. § 61.30. At combined net income of $3,000 monthly, the guideline amount is $644; at $6,000 combined, it rises to $1,121; and at $10,000 combined, it reaches $1,617. The paying parent's share depends on their percentage of combined income and overnight parenting time.
What is the average child support payment in Florida?
Florida does not publish statewide average child support figures because amounts vary significantly based on each family's income, number of children, and custody arrangement. Using guideline amounts, families with combined net income of $6,000 monthly would have obligations of $1,121 for one child, $1,737 for two children, or $2,055 for three children before time-sharing adjustments.
Does child support include health insurance in Florida?
Yes, health insurance premiums for children are added to the basic child support obligation and divided proportionally between parents under Fla. Stat. § 61.30(7). Uncovered medical, dental, and prescription expenses are also allocated proportionally unless the court orders a different arrangement, such as splitting costs 50/50 regardless of income.
How does 50/50 custody affect child support in Florida?
Equal 50/50 custody (182 overnights each) triggers Florida's time-sharing adjustment, reducing but not eliminating child support obligations. Even with equal time, the higher-earning parent typically pays some support to ensure children maintain a consistent standard of living in both homes. The adjustment recognizes that both parents incur direct expenses during their parenting time.
Can child support be reduced if income decreases?
Yes, Florida allows child support modification when income substantially decreases involuntarily. For orders less than 3 years old, the recalculation must show at least a 15% change (minimum $50); for older orders, at least a 10% change (minimum $25). The income decrease must be permanent and involuntary, not self-created through voluntary job changes.
What happens if a parent quits their job to avoid child support?
Florida courts impute income to parents who are voluntarily unemployed or underemployed under Fla. Stat. § 61.30(2)(b). The court assigns an income level based on the parent's work history, qualifications, and community earning levels, then calculates support using that imputed amount. Quitting a job to reduce support obligations typically fails.
At what age does child support end in Florida?
Child support terminates at age 18 in Florida under Fla. Stat. § 61.13. If the child is still in high school at 18 and expected to graduate before turning 19, support continues until graduation or age 19, whichever comes first. Support may continue indefinitely for children with mental or physical disabilities that began before age 18.
Does Florida require parents to pay for college?
No, Florida law does not require parents to pay child support for adult children in college. Courts cannot order college expense payments unless parents previously agreed in writing to provide such support. Voluntary agreements to pay through college are enforceable, but without a written agreement, support terminates at age 18 or high school graduation (up to age 19).
Can back child support be forgiven in Florida?
No, Florida does not forgive child support arrears, and unpaid support remains enforceable indefinitely with no statute of limitations. Arrears cannot be discharged in bankruptcy. Parents who owe back support face continued enforcement through wage garnishment, license suspension, tax intercepts, and potential contempt charges until the full amount is paid.
How long does it take to get a child support order in Florida?
Establishing child support through the Department of Revenue typically takes 30-90 days from application to order entry. Court-filed cases vary based on court calendars and whether the case is contested. Uncontested matters where both parents agree may resolve in 4-6 weeks, while contested cases requiring hearings may take 3-6 months or longer depending on complexity.
