Important Notes for Kansas

  • Kansas uses the Income Shares model, combining both parents' gross incomes to determine the total child support obligation.
  • The Kansas guidelines convert gross income to a "domestic gross income" figure that accounts for maintenance paid or received and other adjustments.
  • Kansas provides a detailed worksheet (Child Support Worksheet) that accounts for parenting time, child care, health insurance, and other factors.
  • The court may deviate from guidelines based on the overall financial condition of the parties and the best interests of the child.

Example Calculation

Scenario: Parent A earns $5,000/month, Parent B earns $3,000/month, 2 children.

Step 1: Combined income: $8,000

Step 2: Parent A's share: $5,000 / $8,000 = 62.5%

Step 3: Look up basic obligation for $8,000 combined and 2 children.

Step 4: Multiply by Parent A's share (62.5%).

Adjustments for health insurance, child care, and parenting time may apply.

Kansas Child Support FAQ

How is child support calculated in Kansas?
Kansas uses the Income Shares model under Kansas Administrative Regulations 29-5-300. Both parents' gross incomes are combined, and the basic child support obligation is determined from the guidelines schedule. Each parent pays their proportional share based on their percentage of the combined income. The Kansas Child Support Worksheet accounts for health insurance, child care, and parenting time adjustments.
What is domestic gross income in Kansas?
Domestic gross income in Kansas is gross income from all sources adjusted for maintenance (alimony) paid to or received from the other parent, court-ordered support for children from other relationships, and FICA taxes. This adjusted figure is used to calculate each parent's share of the child support obligation.
How does shared parenting time affect Kansas child support?
Kansas uses a parenting time adjustment when the non-custodial parent has the children for a significant portion of overnights. The adjustment reduces the child support obligation to reflect the direct costs the non-custodial parent incurs during extended parenting time, typically when they have the children more than 35% of the time.
How long does child support last in Kansas?
In Kansas, child support continues until the child turns 18. If the child is still attending high school as a senior at age 18, support continues until the end of the school year in which the child turns 18. Child support may also continue for a disabled adult child who is unable to support themselves.
Can Kansas child support orders be modified?
Yes, either parent can petition for a modification of child support in Kansas. A modification may be granted if there has been a material change in circumstances, such as a substantial change in income, a change in parenting time, or a change in the child's needs. Kansas recommends reviewing orders every three years.
