How is Child Support Calculated in Kansas?

Kansas calculates support based on the idea that your children should receive the same proportion of parental income as if you were still together. Governed by the Kansas Child Support Guidelines, the court combines both your and the other parent's gross incomes to determine a total support obligation, which is then divided between you based on your percentage share of the combined income.

Understanding the Kansas Parenting Time Adjustment

In Kansas, parenting time directly impacts the final child support amount through a tiered credit system. Under the Kansas Child Support Guidelines, a parent with at least 128 overnights per year (35% of the time) receives a specific percentage reduction in their support obligation. For parents who have equal or nearly equal parenting time, the court uses a different formula called the Shared Expense Formula to adjust support.

Frequently Asked Questions About KS Child Support


At what age does child support end in KS?

Child support in Kansas generally ends when a child turns 18 years old, but it can extend until June 30 of the school year in which the child turns 19 if they are still attending high school. This rule is established by Kansas Statute K.S.A. § 23-3001. Support may terminate earlier if the child becomes emancipated.

How is child support calculated if one parent is unemployed in KS?

If a Kansas parent is unemployed or underemployed without a good reason, a court will typically impute income to them based on their earning capacity. The Kansas Child Support Guidelines authorize the court to base this imputed income on factors like past earnings, education, and job opportunities in the community.

How do I modify a child support order in KS?

You can request to modify a child support order in Kansas if there has been a material change in circumstances, which is presumed if the new calculation results in at least a 10% change in the support amount. Kansas Statute K.S.A. § 23-3005 outlines this standard, requiring the change to be substantial and continuous.

Does KS child support cover college expenses?

No, Kansas law does not require a parent to pay for college expenses as part of a child support order. Child support obligations terminate at the age of majority, and any contribution to post-secondary education costs must be voluntarily agreed upon by the parents in a separate written agreement.

How does KS handle health insurance and childcare costs?

Health insurance premiums and reasonable work-related childcare costs are added to the basic child support obligation and are divided between the parents in proportion to their incomes. The Kansas Child Support Guidelines treat these as necessary expenses required for the care of the child, ensuring both parents contribute fairly.
