§ How Kansas calculates support
Kansas uses the Income Shares model under K.S.A. 23-3002, with guidelines adopted by the Kansas Supreme Court (most recently updated July 1, 2025). It uses 'domestic gross income' — each parent's gross income minus standardized taxes/FICA, preexisting support, and maintenance — to reach Child Support Income; federal and state taxes are built into the schedule, so parents enter gross income. A residential-time credit applies at 128+ overnights; the schedule varies by child age (0–5, 6–11, 12–18). Deviations require written findings.

✦ How to open or modify a case in Kansas
- Apply through Kansas Child Support Services (DCF) or file in court.
- Establish paternity if unmarried (voluntary acknowledgment or genetic testing at state cost).
- Complete the Kansas Child Support Worksheet (published by the Kansas Courts) with both parents' domestic gross income and expenses.
- The court enters an order; the guideline amount is a rebuttable presumption and deviations need written findings.
- Payments go through the Kansas Payment Center (KPC) via income withholding.
- To modify, file a motion showing a material change; arrears keep accruing until the court changes the order.
◈ Illustrative examples
Scenario: Parent A domestic gross $4,300/mo; Parent B $3,200/mo; combined $7,500/mo; one child age 8 (6–11 bracket); child health insurance $100/mo; no childcare; 52 overnights (below 128 credit).
Walk-through: Parent A = 57% of combined. Look up the basic obligation for $7,500 combined and one child (age 6–11) on the Kansas schedule; add health insurance $100. Parent A's share ≈ 0.57 × (basic obligation + $100).
Takeaway: Kansas runs on gross income with taxes embedded in the schedule; the paying parent owes their income percentage of the obligation plus add-ons.
Scenario: Paying parent has 140 overnights/year (above 128 threshold).
Walk-through: A residential-time (parenting-time) credit reduces the transferred amount.
Takeaway: At 128+ overnights the residential-time credit lowers the cash support.
