How Child Support Is Calculated in Iowa
Factors That Affect Child Support in Iowa
Technical details and legal basis
Iowa uses the Income Shares model (Iowa Code § 598.21B) to calculate child support. This model combines both parents' incomes to determine the total obligation, then divides it proportionally based on each parent's share.
Important Notes for Iowa
- • Iowa uses the Income Shares model, combining both parents' net incomes to determine the total child support obligation.
- • Net income is calculated by deducting federal and state taxes, Social Security, Medicare, mandatory retirement contributions, and union dues from gross income.
- • The Iowa schedule divides into three areas: Area A (low-income, NCP income only), Area B (transition), and Area C (combined incomes).
- • The court may deviate from guidelines when a child has extraordinary medical, educational, or special needs.
- • Iowa allows a credit for qualified additional dependent children from other relationships.
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.
