Child support in Kentucky is calculated using an income shares model: both parents’ gross incomes are combined, a total support obligation is pulled from the state guidelines table, and each parent pays their proportional share. The parent without primary custody usually pays their share directly to the other parent, and the amount can be revisited when either parent’s circumstances change by at least 15 percent.
How the Amount Is Calculated
The formula starts with each parent’s monthly gross income. Those figures are added together to produce the combined adjusted parental gross income. The court then looks up the total obligation on Kentucky’s guidelines table, which scales with income and the number of children. Each parent’s share of that obligation matches their percentage of the combined income.
A quick example. If parents together earn $6,000 a month and one earns $4,000, that parent is responsible for roughly two-thirds of the table amount. The other parent covers the remaining third, typically through day-to-day spending on the child.
The guidelines table stops at $15,000 in combined monthly income. Above that, the court has discretion to set a higher amount based on the child’s actual needs, the parents’ finances, and the standard of living the child is used to.1Justia. McCarty v. Faried A judge cannot simply extend the table mathematically; the order has to explain why the specific figure reflects what the child actually needs.
What Counts as Income
Kentucky reads gross income broadly. It covers wages, salaries, commissions, bonuses, retirement and pension distributions, Social Security benefits, workers’ compensation, unemployment insurance, disability benefits, dividends, interest, trust income, capital gains, alimony received, and prizes. Supplemental Security Income and means-tested public assistance such as food stamps are excluded.2Justia. Kentucky Revised Statutes 403.212 – Child Support Guidelines
Self-employment income gets extra scrutiny. The court looks at gross receipts minus ordinary and necessary business expenses, using straight-line depreciation only. Personal expenses run through a business do not count as legitimate deductions, so the number used for child support often looks different from what appears on a tax return.2Justia. Kentucky Revised Statutes 403.212 – Child Support Guidelines
Fringe benefits and in-kind compensation count when they meaningfully reduce a parent’s out-of-pocket costs. A company car, free housing, reimbursed meals, and paid club memberships all qualify. Minor perks do not.
Imputed Income for Voluntary Unemployment
When a parent is voluntarily unemployed or underemployed, the court can calculate support on what that parent could earn rather than what they actually bring in. The judge looks at work history, qualifications, and the wages typical for the person’s field and area. There is no requirement to prove the parent is dodging support on purpose; being voluntarily underemployed is enough.2Justia. Kentucky Revised Statutes 403.212 – Child Support Guidelines
Income cannot be imputed to a parent who is incarcerated, physically or mentally incapacitated, or caring for a child age three or younger for whom both parents share legal responsibility.2Justia. Kentucky Revised Statutes 403.212 – Child Support Guidelines The incarceration exception matters because it prevents a jailed parent from piling up unpayable debt on earnings they cannot generate.
Health Insurance, Medical Costs, and Childcare
Every child support order in Kentucky must address health insurance. If a parent can obtain coverage through an employer or another source at a reasonable cost, the court will order it. Reasonable cost means no more than 5 percent of that parent’s gross income, measured against the cost of adding the child to an existing policy, the difference between single and family coverage, or the cost of a new policy for the child. Both parents can agree, or the court can find good cause, to allow coverage that exceeds 5 percent.3Kentucky Legislative Research Commission. Chapter 82 HB 489 – Health Care Coverage in Child Support
Premium costs are folded into the overall calculation and split by each parent’s share of income. If neither parent has affordable employer-sponsored coverage available, the court may order contributions toward a private policy or the Kentucky Children’s Health Insurance Program.
Uninsured medical expenses — copays, deductibles, and treatments not covered by insurance — are divided between the parents in proportion to income, on top of the base support amount. A parent who consistently refuses to pay their share can be held in contempt.
Work-related or school-related childcare gets the same treatment. When the custodial parent needs childcare to work or attend school, those costs are added to the calculation and split proportionally. A parent who thinks the chosen provider is overpriced or unnecessary has to present evidence to that effect.
Shared Custody and Other Deviations
The standard calculation assumes one parent has primary physical custody. When physical custody is closer to equal, the court can deviate from the guidelines to reflect the reality that both households are spending directly on the child. Kentucky’s Court of Appeals recognized this in Downey v. Rogers, noting that fixed expenses like housing continue regardless of where the children sleep on any given night.4Justia. Downey v. Rogers
Courts can also deviate when the guideline amount would produce an unjust result. Common grounds include one parent covering private school tuition or extracurricular costs directly, or a parent supporting children from another relationship. Any deviation requires specific written findings explaining why the standard number does not serve the child’s best interests.
Low-Income Floor
The guidelines include a self-support reserve of $915 per month, the minimum a parent needs for basic living expenses. When the paying parent’s income sits near or below that line, the court reduces the obligation to avoid pushing them into poverty. Even so, the minimum monthly support amount is $60.5Kentucky Legislative Research Commission. Kentucky Revised Statutes 403.212 – Child Support Guidelines
When Support Ends
Child support obligations end when the child is emancipated, which usually happens at age 18. There is one important exception: if the child is still a high school student at 18, support continues through the end of the school year in which the child turns 19.6Kentucky Legislative Research Commission. Kentucky Revised Statutes 403.213 – Criteria for Modification of Orders for Child Support Marriage also emancipates a child and ends the obligation. Parents can agree in writing to extend support past these default endpoints, but without such an agreement, it stops automatically.
Kentucky does not generally require parents to pay for college or support an adult child who is still in school after high school. Support for a disabled adult child who cannot earn a living may continue under other legal theories, and families in that position should consult an attorney because the rules are less settled.
Modifying an Order
Either parent can ask the court to change the order when circumstances shift. The change must be both material and continuing, so short-term fluctuations usually will not qualify. If running the current numbers through the guidelines produces a result at least 15 percent higher or lower than the existing order, that creates a rebuttable presumption of a material change. A difference under 15 percent is presumed not to qualify, though a parent can try to overcome that presumption with additional evidence.6Kentucky Legislative Research Commission. Kentucky Revised Statutes 403.213 – Criteria for Modification of Orders for Child Support
To start, the parent seeking the change files a motion with the family court that issued the original order, along with pay stubs, tax returns, or medical bills documenting the change. If both parents agree on a new amount, they can submit a written agreement for court approval. If they disagree, the court holds a hearing.
File quickly. A modification takes effect on the date the motion is filed, not the date circumstances actually changed, and it cannot be applied backward to payments already due.6Kentucky Legislative Research Commission. Kentucky Revised Statutes 403.213 – Criteria for Modification of Orders for Child Support A parent who loses a job in January but waits until June to file owes the full original amount for those five months.
Incarceration
Kentucky law treats incarceration as not being voluntary unemployment, so a jailed parent’s income cannot be imputed.2Justia. Kentucky Revised Statutes 403.212 – Child Support Guidelines Federal rules reinforce this and prohibit states from blocking a modification request based on incarceration. When the state learns a noncustodial parent will be incarcerated for more than 180 days, it must either open a review or notify both parents of their right to request one within 15 business days.7Administration for Children and Families. Flexibility, Efficiency, and Modernization in Child Support Enforcement Programs – Modification for Incarcerated Parents Without a modification, the original amount continues to accrue as debt.
Enforcement
Child support enforcement in Kentucky is handled by the Department of Child Support Services under the Office of the Attorney General.8Kentucky Child Support. Home – Kentucky Child Support The agency has several tools.
Income Withholding
The most common method is income withholding: the employer deducts support directly from the paying parent’s paycheck, and the deduction reaches wages, commissions, bonuses, and retirement benefits. Most new orders include automatic withholding, so the deduction begins without waiting for a missed payment.
Tax Refund Intercepts, Liens, and Credit Reporting
Kentucky can intercept both federal and state tax refunds to recover overdue support.9Justia. Kentucky Revised Statutes 205.769 – Federal and State Income Tax Refund Offsets For federal intercepts, the standard thresholds are $150 in arrears for families receiving public assistance and $500 for those who are not. Delinquent parents can also be reported to credit bureaus, and the state can place liens on real estate, vehicles, and bank accounts, blocking sale or transfer until the debt is cleared.
License Suspension
When arrears equal or exceed six months of cumulative nonpayment, the Transportation Cabinet can deny or suspend the parent’s driver’s license. The suspension lasts until the arrears are eliminated or the parent is paying under a court or administrative order.10Kentucky Legislative Research Commission. Kentucky Revised Statutes 186.570 – Denial or Suspension of License
Contempt and Criminal Charges
A parent who refuses to pay despite having the ability can be held in contempt of court, which carries potential jail time. Kentucky also criminalizes nonsupport under KRS 530.050, with escalating minimum jail sentences for repeat offenses. A criminal nonsupport charge is separate from civil contempt and produces a criminal record.
Interstate Cases
When parents live in different states, Kentucky follows the Uniform Interstate Family Support Act, codified at KRS 407.5101 through 407.5902. Only one valid support order exists at a time, and UIFSA sets which state has authority to modify it. A Kentucky court can exercise jurisdiction over an out-of-state parent if that parent previously lived in Kentucky, if the child was conceived in Kentucky, or if the parent has other significant connections to the state.
A custodial parent in Kentucky can request help from the Department of Child Support Services or file directly with the other state’s enforcement agency. If Kentucky lacks jurisdiction over the noncustodial parent, the case transfers to the state where that parent lives.
Federal law also reaches the worst interstate cases. Under 18 U.S.C. § 228, a parent who willfully fails to pay support for a child in another state can face federal charges if the debt has gone unpaid for more than a year or exceeds $5,000. A first offense carries up to six months in prison. If the debt has been unpaid for more than two years or exceeds $10,000, or if the parent has a prior conviction, the maximum rises to two years. Courts must also order restitution equal to the full amount unpaid.11Office of the Law Revision Counsel. 18 USC 228 – Failure to Pay Legal Child Support Obligations
Taxes
Child support payments are not tax-deductible for the paying parent and not taxable income for the receiving parent.12Internal Revenue Service. Tax Information for Non-Custodial Parents This differs from alimony, where the tax treatment depends on when the divorce was finalized. The one tax issue that regularly comes up is which parent claims the child as a dependent, and that is controlled by the custody arrangement and any agreement between the parents, not by the support order.
