Kansas uses the income-shares model: both parents' incomes are combined and each parent owes their proportional share of the official schedule amount (K.S.A. 20-165; Kansas Supreme Court Administrative Order 2025-RL-121 (2024 Kansas Child Support Guidelines, effective July 1, 2025)). Kansas's official tables have extra dimensions this quick tool can't capture — use the official worksheet linked above for your figure; this page explains what drives it.
How Kansas Calculates Child Support
Kansas uses the Income Shares model: both parents' combined domestic gross income (adjusted for certain deductions) is used to find a single basic child support obligation on the official Schedule of Child Support Obligations, which is then prorated between the parents by their share of combined income. Kansas guidelines are unusual because the schedule is staggered by the child's age — 0-5, 6-11, and 12-18 — not only by combined income and number of children, since the underlying economic data show that older children cost more to support. The current version is the '2024 Kansas Child Support Guidelines,' adopted by the Kansas Supreme Court via Administrative Order 2025-RL-121, effective July 1, 2025. (Because the official tables are age-banded, this page links to the official worksheet rather than reproducing a single lookup table.)
Statutory basis: K.S.A. 20-165; Kansas Supreme Court Administrative Order 2025-RL-121 (2024 Kansas Child Support Guidelines, effective July 1, 2025). Exact figure: official Kansas calculator.
Worked Example
Example (one child, age 8, in the 6-11 age bracket): Parent A earns $3,200/month gross and Parent B earns $1,800/month gross, for $5,000 combined monthly domestic gross income. The official Schedule of Child Support Obligations sets the basic obligation for one child age 6-11 at that combined income level at $904/month. Each parent's share is then prorated by their percentage of combined income (Parent A 64% → $578.56; Parent B 36% → $325.44) before any parenting-time, health-insurance, or child-care worksheet adjustments are applied.
When Courts Deviate From the Guideline
- Long-distance parenting-time travel costs
- Income tax filing considerations
- A child's special needs
- Extending support past the age of majority for a child still in high school
- The overall financial condition of the parties
- An equal (50/50) parenting-time schedule (Equal Parenting Time Adjustment)
Frequently Asked Questions
Is there a cap on how much child support can be ordered in Kansas?
Not a hard statutory cap. The official schedule runs up to $10,900 in combined monthly domestic gross income (at that top row, one child costs $1,464/month at age 0-5, $1,638/month at age 6-11, or $1,743/month at age 12-18). Above $10,900 combined income, the guidelines direct courts to use an 'extended formula' and set the amount at their discretion rather than reading it off a fixed table.
What counts as income under the Kansas child support guidelines?
The guidelines start from each parent's 'Domestic Gross Income' — income from all sources that is regularly or periodically received (wages, bonuses, commissions, self-employment, military pay, etc.), excluding public assistance and child support received for other children. That gross figure is then adjusted (e.g., for support already owed for other children or court-ordered maintenance) before the combined 'child support income' is used to look up the schedule.
How does 50/50 (equal) parenting time change the calculated amount?
Kansas applies an Equal Parenting Time Adjustment: the lower of the two parents' adjusted subtotals is subtracted from the higher adjusted subtotal, and the difference is divided by two — meaning the higher earner pays half the gap between what each parent's household would otherwise owe, rather than the full basic obligation from the schedule.
Until what age does child support run in Kansas — does it cover college?
Under K.S.A. 23-3001, support generally terminates when the child turns 18, but continues through June 30 of the school year in which the child turns 18 if the child is still a bona fide high school student, and can be extended by the court through the school year the child turns 19 under the same condition. Kansas does not automatically require support through college; support past the age of majority only continues if the parents have a written agreement approved by the court.
