Factors That Affect Child Support in Arizona
Important Notes for Arizona
- Arizona uses the Income Shares model, combining both parents' adjusted gross incomes to determine the total child support obligation.
- Adjusted gross income is calculated by subtracting court-ordered support for other children, spousal maintenance paid, and certain mandatory deductions from gross income.
- Arizona provides a parenting time adjustment when the non-custodial parent has the children for more than 100 overnights per year (approximately 28% of the time).
- The court may deviate from guidelines based on the best interests of the child, including educational expenses, extraordinary medical costs, or special needs.
Example Child Support Calculation in Arizona
Scenario: Parent A earns $5,000/month, Parent B earns $3,000/month, 2 children.
Step 1: Combined monthly income: $5,000 + $3,000 = $8,000
Step 2: Parent A's income share: $5,000 / $8,000 = 62.5%
Step 3: Look up basic obligation from the guidelines schedule for $8,000 combined income and 2 children.
Step 4: Multiply the basic obligation by Parent A's share (62.5%) to determine their payment.
Note: Additional adjustments for health insurance, child care, and parenting time may apply.
