How Child Support Is Calculated in Alaska
Factors That Affect Child Support in Alaska
Technical details and legal basis
Alaska uses the Percentage of Income model (AK Guidelines (Alaska R. Civ. P. 90.3)) to calculate child support. This means child support is based on a set percentage of the non-custodial parent's net income, with the percentage increasing for more children.
Important Notes for Alaska
- • Alaska uses a modified Percentage of Income model based on the non-custodial parent's adjusted annual net income.
- • Adjusted annual income is calculated by deducting federal and state taxes, Social Security, Medicare, mandatory retirement contributions, and prior child support obligations from gross income.
- • For shared custody situations where each parent has the children more than 30% of the time, Alaska applies a formula that accounts for both parents' incomes.
Example Calculation
Scenario: Non-custodial parent earns $5,000/month net income, 2 children.
Step 1: Determine net monthly income: $5,000
Step 2: Apply the guideline percentage for 2 children: 27%
Step 3: Calculate: $5,000 × 27% = $1,350/month
