How Kansas Child Support Is Calculated

Kansas uses the Income Shares Model to determine child support obligations. Kansas uses the Income Shares model with both parents' gross monthly incomes. Kansas has published support tables. Support ends at age 18 or high school graduation. For children in technical or vocational programs, support may continue through the program.

Kansas applies an adjustment when the non-custodial parent has 35% or more of parenting time. Kansas also adjusts for multiple families — if the obligor has children from other relationships, their income available for support is reduced.

Kansas courts use the Income Shares Model worksheets for official calculations. Kansas provides Child Support Guidelines and worksheets but does not have an official public calculator. Contact the Kansas Department for Children and Families (DCF) or a family law attorney for calculations.

Worked Example: Kansas Child Support

Alex earns $5,500/month gross income. Jordan earns $3,200/month. They have 2 children in Kansas. Alex has primary custody; Jordan has standard visitation (every other weekend, approximately 73 overnights/year).

Combined monthly income: $5,500 + $3,200 = $8,700
Basic support (2 children, ~25% of combined): $8,700 × 25% = $2,175/month
Jordan's income share: $3,200 / $8,700 = 36.8%
Jordan's proportional share: $2,175 × 36.8% = $800/month
Health insurance add-on (paid by Alex, Jordan's share): +$74/month
Childcare add-on (Jordan's proportional share of $600): +$221/month
Custody adjustment (73 nights — no adjustment): $0
ESTIMATED SUPPORT: ~$1,095/month

This example uses approximate calculations. Actual Kansas child support requires the official Income Shares Model worksheet or software and should be verified with a licensed family law attorney or the court.

Key Factors That Affect Kansas Child Support

  • Both Parents' Income

    Kansas's Income Shares Model combines both parents' incomes to determine the total family resources available for the children. A higher combined income results in higher support — reflecting the idea that children should benefit from the family's overall financial resources regardless of which parent they primarily reside with.

  • Custody and Parenting Time

    Kansas adjusts child support based on the amount of parenting time each parent has. More overnight time with the paying parent generally reduces the support obligation — reflecting that the paying parent directly absorbs the children's costs during their parenting time. Kansas applies an adjustment when the non-custodial parent has 35% or more of parenting time.

  • Health Insurance and Childcare

    Health insurance premiums for the children and work-related childcare costs are added to the basic child support obligation in Kansas. The cost is typically split proportionally based on each parent's share of combined income. These add-ons can significantly increase the total support obligation, particularly in cases with high childcare or health insurance costs.

Frequently Asked Questions

How is child support calculated in Kansas?

Kansas uses the Income Shares Model to calculate child support. Kansas uses the Income Shares model with both parents' gross monthly incomes. The guideline amount is the starting point, but courts may deviate based on special circumstances such as a child's extraordinary medical needs, travel costs for visitation, or significantly different financial situations from the guideline assumptions. Always confirm your specific calculation with a Kansas family law attorney.

What income is used to calculate child support in Kansas?

Kansas uses both parents' gross monthly income as the starting point for child support calculations, combining them into a total family income figure. Courts may also impute income to a parent who is voluntarily underemployed or unemployed without good cause — meaning they may be held to what they could earn rather than what they actually earn.

Does 50/50 custody mean no child support in Kansas?

No. In Kansas, shared custody reduces but does not eliminate child support in most cases. When both parents share custody equally, Kansas typically uses an offset method where each parent's guideline support is calculated and the higher earner pays the difference. The goal is to ensure the children maintain a similar standard of living in both households. If incomes are nearly equal, the resulting payment may be very small, but it rarely drops to zero unless incomes are identical.

How long does child support last in Kansas?

In Kansas, child support generally continues until the child reaches the age of majority (typically age 18), graduates from high school, or is otherwise emancipated — whichever occurs later up to the state maximum. Courts may also continue support for adult disabled children who cannot support themselves. Support does not automatically end — the paying parent must file for termination when the child ages out or becomes emancipated.

Can Kansas child support be modified?

Yes. Kansas child support can be modified when there is a substantial change in circumstances. Most states, including Kansas, require that the new calculated amount differ from the existing order by at least 15% — or that three years have passed since the order was entered, triggering an automatic review. Changes that typically qualify include significant income changes for either parent, a change in custody arrangement, a child's new medical needs, or loss of health insurance coverage. Modifications require filing a motion with the family court — the original order remains in effect until a new order is entered.
