Frequently Asked Questions

Common questions about Kentucky child support

How is child support calculated in Kentucky?

Kentucky uses the income shares model under KRS 403.212. Both parents' monthly adjusted gross incomes are combined and looked up in the statutory Child Support Guidelines Table (effective July 1, 2025), which gives a basic support obligation based on combined income and number of children. Work-related childcare and the child's health insurance are added, then the total is divided in proportion to each parent's share of the combined income. The paying parent's share is the support amount, reduced by any shared parenting time credit under KRS 403.2122.

What counts as gross income in Kentucky child support?

Gross income in Kentucky includes income from all sources including wages, salaries, commissions, bonuses, self-employment income, dividends, severance pay, pensions, interest, trust income, annuities, Social Security benefits, unemployment benefits, disability insurance, and workers' compensation. Under KRS 403.212, Kentucky courts may impute income to a parent who is voluntarily unemployed or underemployed.

How does parenting time affect Kentucky child support?

Under KRS 403.2122, a paying parent who has the child for at least 88 days per year (a 'day' is more than 12 consecutive hours of care) can receive a shared parenting time credit. The credit is a percentage of the total support obligation set by a statutory chart that rises with the number of days: 15% at 88-115 days, 20.5% at 116-129, 25% at 130-142, 30.5% at 143-152, 36% at 153-162, 42% at 163-172, 48.5% at 173-181, and 50% at roughly equal (182-182.5) parenting. The credit is subtracted from the paying parent's monthly obligation. The self-support reserve and the shared parenting credit are not applied together, and courts retain discretion.

Can Kentucky child support be modified?

Yes, either parent can petition to modify child support when there has been a material change in circumstances. Kentucky allows modification if the current order differs from the recalculated guideline amount by 15% or more, which is generally treated as a material change. Common reasons include significant income changes, changes in parenting time, changes in childcare or medical costs, or a child aging out of the order.

How long does child support last in Kentucky?

In Kentucky, child support generally continues until the child turns 18. If the child is still a full-time high school student at 18, support continues until graduation or age 19, whichever comes first. Support may continue past 18 for a child with a severe mental or physical disability. Kentucky courts generally cannot order parents to pay for college as part of child support.

Are childcare and health insurance included in the calculation?

Yes. Under Kentucky's guidelines, work-related childcare costs and the cost of health insurance for the child are added to the basic child support obligation before it is divided between the parents. Each parent's share of these additional costs is proportional to their share of the combined gross income.

Is this calculator accurate for my situation?

This calculator provides an estimate based on the Kentucky child support guidelines. Actual court-ordered support may differ because judges may deviate from the guidelines based on factors including the child's extraordinary needs, extraordinary expenses, the financial resources of each parent, and other relevant circumstances. Consult a Kentucky family law attorney for an accurate assessment.
