Every child support calculation starts in the same place: figuring out what each parent earns. At first glance, this seems like it would be simple, but “income” for child support purposes is defined much more broadly than a single paycheck. Bonuses, benefits, rental income, and even income a parent isn’t currently earning but could be earning can all factor into the number.
Because Eaton Family Law handles cases in both Florida and Tennessee, this is a question that comes up constantly, and honestly, the two states agree on far more than they disagree on. Below is a breakdown of what typically counts, what usually doesn’t, and where the two states part ways.
What “Income” Means for Child Support Purposes
Both Florida and Tennessee use an income shares model, which means the entire calculation depends on an accurate income figure for both parents, and courts are not limited to a W-2 or a pay stub. The definition of income is intentionally broad so that a parent can’t shield money from the calculation simply because it doesn’t come from a traditional job.
Types of Income That Generally Count
In both states, the following are typically included when calculating income for child support:
- Wages, salaries, commissions, bonuses, and overtime
- Self-employment or business income, calculated as gross receipts minus ordinary and necessary business expenses
- Disability, workers’ compensation, and unemployment or reemployment benefits
- Pension, retirement, and annuity payments
- Social Security benefits
- Alimony or spousal support received from a different case
- Interest, dividends, and capital gains
- Rental income
- Royalties, trust income, and estate income
What Usually Doesn’t Count
Means-tested public assistance benefits are generally excluded from income in both states. This includes benefits like Temporary Assistance for Needy Families (TANF), Supplemental Security Income (SSI), and food assistance programs. Child support received for other children is also generally excluded, since that money already belongs to a different child’s support obligation, not the parent’s personal income.
What Happens If a Parent Isn’t Working, or Isn’t Working Enough?
Both Florida and Tennessee allow a court to impute income to a parent who is voluntarily unemployed or underemployed. This means if the court finds the parent is deliberately working less, or not at all, to reduce their support obligation, the court can calculate support based on what a parent is capable of earning rather than what they’re currently reporting. Courts generally look at the parent’s recent work history, education, job skills, and the realistic job market in their area before assigning an imputed income figure. This does not apply to a parent who is genuinely unable to work due to a documented disability or other circumstances outside their control.
Florida’s Net Income Approach vs. Tennessee’s Gross Income Approach
This is the biggest structural difference between the two states. Florida calculates support based on net income, or gross income minus taxes, mandatory retirement contributions, health insurance premiums, and certain other court-ordered obligations. Tennessee calculates support based on gross income, adjusted with credits for other children and existing support orders, but without subtracting taxes first.
In practice, this means the same paycheck can run through two different formulas depending on which state has jurisdiction over the case, which is one reason a Florida calculation and a Tennessee calculation can land on different numbers even when the raw income looks the same.
Why Getting the Income Number Right Matters So Much
Because both states build their entire formula on top of the income figures, a mistake at this stage carries through the whole calculation. Missing a source of income, failing to account for imputed income, or misclassifying a self-employed parent’s business expenses can meaningfully change the final support number in either direction. This is usually the first thing worth double-checking, whether you’re setting up a new order or reviewing one that already exists.
Frequently Asked Questions
Does overtime count as income for child support?
Yes, in both Florida and Tennessee, overtime pay is included in gross income calculations, along with bonuses and commissions.
Is a new spouse’s income counted?
No. A parent’s new spouse’s income is not counted as that parent’s income for child support purposes in either state, though it can sometimes come up in other financial contexts.
What if a parent is self-employed and their income varies month to month?
Courts typically look at business records over a representative period, often the past year or more, to establish an average monthly income figure instead of relying on a single month.
Can a court use last year’s tax return to determine income?
Tax returns are a common starting point, but courts in both states can also look at current pay stubs, business records, and other documentation, especially if a parent’s income has changed since the last filing.
What if a parent is intentionally hiding income?
Both states allow discovery tools, such as requests for financial records and depositions, to uncover unreported or hidden income, and a court can impute income if it finds a parent is not being truthful about their earnings.
Next Step
Because the income calculation is the foundation of every child support case, getting it right from the start can save significant time and conflict later. Catherine Eaton helps parents in both Florida and Tennessee build accurate financial pictures and resolve support questions collaboratively whenever possible.
