Florida Child Support Laws: Guidelines and Calculations

How Florida Determines Child Support

Florida calculates child support using the Income Shares Model. This approach estimates what both parents would have collectively spent on their children if the family remained in one household. The court then divides that amount between the parents based on each parent\u2019s share of combined net income.

The governing statute is Fla. Stat. \u00a7 61.30, which sets out the guidelines schedule, allowable deductions, and deviation factors. Additional provisions for support obligations and health insurance appear in Fla. Stat. \u00a7 61.13.

Step-by-Step Calculation Process

Florida courts follow a structured process to arrive at a child support amount:

1. Determine each parent\u2019s gross income from all sources.
2. Subtract allowable deductions to arrive at each parent\u2019s net income.
3. Combine both parents\u2019 net incomes.
4. Look up the minimum child support need on the guidelines schedule based on combined income and number of children.
5. Calculate each parent\u2019s percentage share of combined income.
6. Multiply the minimum support need by each parent\u2019s percentage.
7. Adjust for childcare costs, health insurance premiums, and time-sharing arrangements.

The result is the presumptive child support amount. Courts can deviate from this amount, but they need specific reasons to do so.

What Counts as Gross Income

Under Fla. Stat. \u00a7 61.30(2), gross income includes nearly every source of money a parent receives:

• Salary, wages, bonuses, commissions, and tips
• Business income (gross receipts minus ordinary and necessary business expenses)
• Disability and workers\u2019 compensation benefits
• Unemployment compensation
• Pension, retirement, and Social Security benefits
• Spousal support received from a previous marriage
• Interest, dividends, and rental income
• Royalties, trusts, and estate income
• Reimbursed expenses or in-kind benefits that reduce personal living expenses

Public assistance benefits (such as Temporary Assistance for Needy Families) are excluded from gross income calculations.

Imputed Income

If a parent is voluntarily unemployed or underemployed, the court may impute income based on that parent\u2019s earning capacity. Under current law, there is a rebuttable presumption that a voluntarily unemployed or underemployed parent earns the median income of year-round, full-time workers as reported by the U.S. Census Bureau.

The court considers the parent\u2019s recent work history, qualifications, and local job availability when imputing income. Importantly, incarceration cannot be treated as voluntary unemployment under Florida law.

Allowable Deductions

To calculate net income, parents subtract the following from gross income:

• Federal, state, and local income taxes (based on filing status and allowable dependents)
• Federal Insurance Contributions Act (FICA) and self-employment taxes
• Mandatory union dues and mandatory retirement contributions
• Health insurance premiums (excluding the portion covering the child)
• Court-ordered support payments for other children that are actually being paid
• Court-ordered spousal support from a previous marriage that is actually being paid

Voluntary deductions, such as elective 401(k) contributions beyond mandatory amounts, are generally not subtracted.

The Guidelines Schedule

Florida\u2019s guidelines schedule in Fla. Stat. \u00a7 61.30(6) provides the minimum child support need based on combined monthly net income and the number of children. Below are selected examples from the schedule:

Combined Monthly Net Income	1 Child	2 Children	3 Children
$1,000	$235	$365	$397
$2,500	$547	$847	$1,061
$5,000	$1,000	$1,551	$1,939
$7,500	$1,225	$1,900	$2,378
$10,000	$1,437	$2,228	$2,795

For combined monthly net incomes above $10,000, the court applies the $10,000 schedule amount plus a percentage of the income exceeding $10,000. Those percentages are:

• 1 child: 5% of excess income
• 2 children: 7.5% of excess income
• 3 children: 9.5% of excess income
• 4 children: 11% of excess income
• 5 children: 12% of excess income
• 6 children: 12.5% of excess income

There is no statutory maximum. The guidelines scale upward based on actual combined income.

Time-Sharing Adjustments

Florida law adjusts the child support calculation when a parent exercises at least 20% of overnights with the child. That threshold equals approximately 73 nights per year.

The adjustment formula under Fla. Stat. \u00a7 61.30(11)(b) works as follows:

1. Calculate each parent\u2019s base support obligation (before adding childcare and health insurance costs).
2. Multiply each parent\u2019s obligation by 1.5.
3. Determine each parent\u2019s percentage of overnight stays.
4. Multiply each parent\u2019s adjusted obligation by the other parent\u2019s percentage of overnights.
5. Subtract the smaller amount from the larger. The difference is the support transfer amount.
6. Add each parent\u2019s share of childcare and health insurance costs.

This adjustment recognizes that parents incur direct expenses (food, utilities, transportation) when children are in their care. Parents with substantial time-sharing typically pay less in support than the basic calculation alone would produce.

Health Insurance Requirements

Every Florida child support order must include a provision for health insurance coverage for the child, per Fla. Stat. \u00a7 61.13(1)(b). Health insurance is presumed reasonable in cost if the incremental cost of adding the child does not exceed 5% of the responsible parent\u2019s gross income.

If health insurance costs exceed that 5% threshold, the court may still order coverage but must make a written finding explaining why the deviation is appropriate. The parent providing coverage receives a credit in the child support calculation for the child\u2019s share of the premium.

Noncovered medical, dental, and prescription expenses are divided between the parents in proportion to their respective shares of combined net income.

When Courts Can Deviate from the Guidelines

Florida courts can adjust child support by up to 5% from the guidelines amount without a written explanation, as long as they consider all relevant factors. For deviations greater than 5%, the court must issue a written finding explaining why the guidelines amount would be unjust or inappropriate.

Deviation factors under Fla. Stat. \u00a7 61.30(11)(a) include:

• Extraordinary medical, psychological, educational, or dental expenses
• Independent income of the child
• The obligee parent\u2019s low income and ability to maintain the basic necessities of the home
• Whether seasonal variations in a parent\u2019s income affect the support amount
• The age of the child, taking into account greater needs of older children
• Special needs such as costs for a child with a disability
• Total available assets of each parent and the child
• The impact of IRS dependency exemptions and tax credits
• Whether either parent will actually exercise the court-ordered time-sharing schedule

The court weighs these factors on a case-by-case basis.

Modifying a Child Support Order

Florida allows modification of an existing child support order when there is a substantial change in circumstances. The difference between the current order and a new guidelines calculation must meet one of these thresholds:

• At least 15% of the current order, OR
• At least $50, whichever is greater

Common Grounds for Modification

• A significant increase or decrease in either parent\u2019s income
• Changes in childcare or health insurance expenses
• Termination or modification of alimony
• Changes in the time-sharing arrangement
• A child\u2019s changed needs (medical condition, educational requirements)
• A parent\u2019s failure to exercise the court-ordered time-sharing schedule (when not caused by the other parent)

When a parent fails to exercise their time-sharing as ordered, the court may modify support retroactive to when the failure began.

How to File for Modification

To petition for a modification, a parent files a Supplemental Petition for Modification at the circuit court clerk\u2019s office in the county where the current order was entered. The Florida Courts website provides the required child support guidelines worksheet and related forms.

Modifications generally take effect from the date the petition is filed, not from the date circumstances changed. Filing promptly after a qualifying change matters.

Retroactive Child Support

In initial child support determinations (such as paternity actions or first-time petitions), the court can award support retroactive to when the parents stopped living together. However, the retroactive period cannot exceed 24 months before the filing date.

The court applies the guidelines schedule in effect at the time of the hearing and considers any voluntary payments the obligor already made during the retroactive period.

Establishing Paternity for Child Support

Before a court can order child support from an unmarried father, paternity must be legally established. Florida law under Chapter 742 provides several paths:

• Voluntary Acknowledgment: Both parents sign a notarized acknowledgment of paternity at the hospital or later.
• Administrative Order: The Florida Department of Revenue can establish paternity through genetic testing as part of the child support enforcement process.
• Court Action: Either parent (or the child) can file a paternity action in circuit court. The court can order genetic testing, and test results showing a probability of paternity of 95% or greater create a rebuttable presumption of paternity.

Once paternity is established, the court can order temporary child support even while the case is still pending, provided there is clear and convincing evidence of parentage.

Enforcement of Child Support Orders

Florida provides extensive enforcement tools through both the Florida Department of Revenue, Child Support Program and the courts.

Administrative Enforcement

The Department of Revenue can pursue the following remedies without going to court:

• Income withholding: Wages garnished directly from the employer
• Tax refund interception: Federal and state refunds seized when $500 or more is owed
• Lottery winnings seizure: Amounts over $600 intercepted
• Bank account levy: Funds seized when $600 or more is owed
• Property liens: Placed on real estate and vehicles
• Passport denial: Reported to the U.S. State Department when $2,500 or more is owed
• Credit reporting: Delinquencies reported to credit bureaus

License Suspension

Under Fla. Stat. \u00a7 409.2564, the Department of Revenue can initiate suspension of a delinquent parent\u2019s driver\u2019s license, professional license, business license, and recreational licenses. The parent receives a notice and has 30 days to begin paying, enter a payment agreement, or contest the action.

Court Enforcement (Contempt)

A custodial parent or the Department of Revenue can file a motion for civil contempt. If the court finds the parent willfully failed to pay despite having the ability to do so, penalties include:

• Incarceration for up to one year per violation
• Purge conditions (the parent can be released upon making a specified payment)
• Attorney\u2019s fees and court costs

Criminal Penalties

Under Fla. Stat. \u00a7 827.06, willful failure to provide support is a first-degree misdemeanor, punishable by up to one year in jail and a $1,000 fine.

The charge escalates to a third-degree felony if the parent has four or more prior violations or owes more than $5,000 in arrears accumulated over more than one year. A third-degree felony carries up to five years in prison and a $5,000 fine. Upon conviction, the court orders restitution equal to the total unpaid support.

There is no statute of limitations on collecting child support arrears in Florida.

When Does Child Support End in Florida?

Florida child support typically terminates when the child:

• Turns 18, OR
• Turns 19 if still enrolled in high school, performing in good faith, and reasonably expected to graduate before age 19, OR
• Becomes legally emancipated, OR
• Marries, OR
• Joins the armed forces

Support may continue indefinitely for a child who is mentally or physically incapacitated and dependent on the parent.

Emancipation in Florida

A minor in Florida can petition for emancipation under Fla. Stat. \u00a7 743.015. Requirements include:

• The minor is at least 16 years old
• The minor is financially self-sufficient or has a plan for self-support
• The court determines emancipation serves the minor\u2019s best interest

Once a child is legally emancipated, the parent\u2019s child support obligation ends.

Termination Date in the Order

Florida law requires that every child support order specify the exact month, day, and year that support terminates or is reduced (for example, when one child in a multi-child order ages out). Parents do not need to file a separate motion to stop payments on the termination date if the order already includes it.

Applying for Child Support Services

Parents who need help establishing, collecting, or enforcing child support can contact the Florida Department of Revenue, Child Support Program. Services include:

• Locating an absent parent
• Establishing paternity through genetic testing
• Obtaining an initial child support order
• Enforcing an existing order
• Modifying an existing order when circumstances change

These services are available regardless of income level. The program serves both custodial and noncustodial parents.
