Kansas Child Support Guidelines
Kansas uses the Kansas Child Support Guidelines (Kansas Supreme Court Administrative Order) to determine child support obligations. Under the Income Shares model, both parents' incomes are combined to estimate what the family would have spent on the child if the household were intact. The obligation is then divided proportionally based on each parent's contribution to combined gross income.
Kansas has several distinctive features in its child support system. Kansas uses "Domestic Gross Income" — a broader definition that includes in-kind benefits like employer-provided housing. The state provides its own Excel-based calculator that judges and attorneys commonly use. Kansas includes a Long Distance Parenting Time adjustment for travel costs when parents live far apart.
Kansas bases calculations on gross income — meaning income before taxes and deductions. This includes wages, salaries, commissions, bonuses, self-employment income, and other sources. The self-support reserve in Kansas is $1,225/month, ensuring the paying parent retains enough income to cover basic living expenses.
How Kansas Calculates Child Support
Kansas follows a 6-step process under the Kansas Child Support Guidelines (Kansas Supreme Court Administrative Order):
- 1
Determine each parent's Domestic Gross Income (including in-kind benefits)
- 2
Subtract maintenance paid, child support for prior children, and employer-paid health insurance
- 3
Combine adjusted incomes and find the basic obligation from the Kansas schedule
- 4
Prorate based on each parent's income share
- 5
Apply shared residency adjustment if the non-custodial parent has 128+ overnights
- 6
Add child care and health insurance costs proportionally

Custody Time Adjustments in Kansas
Kansas recognizes "Shared Residency" when the non-custodial parent has the children for at least 128 overnights per year (approximately 35% of the time). When this threshold is met, the standard child support formula is adjusted to reflect the increased direct expenses borne by both parents.
Under Kansas' Income Shares approach, the shared parenting adjustment typically calculates each parent's obligation based on their income share, then applies a credit or cross-calculation that accounts for the time each parent directly supports the child. The more overnights the non-custodial parent has, the greater the reduction in their payment — but the adjustment is not dollar-for-dollar because fixed costs like housing don't decrease when the child is away.
Below 128 overnights, Kansas generally treats the arrangement as a sole custody situation with standard visitation, and no custody time adjustment is applied to the child support calculation.

How to Reduce Child Support Costs in Kansas
While child support is determined by Kansas' guidelines, there are legitimate ways to ensure your obligation is calculated fairly.
Increase Parenting Time
In Kansas, more overnights with your children can reduce your support obligation. Document actual time spent and request a formal custody modification if needed.
Ensure Accurate Income Reporting
Both parents' incomes must be reported accurately. Verify that bonuses, overtime, and variable income are averaged correctly over the appropriate period.
Claim All Allowable Deductions
Kansas allows deductions for items like mandatory retirement contributions, union dues, and health insurance premiums. Make sure all qualifying deductions are included.
Request a Modification When Eligible
If your income has decreased by 15-25% or more, you may qualify for a modification. File promptly — changes are typically not retroactive before the filing date.
Account for Other Children
If you have other children you're legally obligated to support, this can be factored into the calculation as a deduction in most states.
Review Healthcare & Childcare Costs
Ensure shared expenses like health insurance and childcare are divided proportionally. If costs have changed, update the court.
