How Child Support Is Calculated in Alaska

Factors That Affect Child Support in Alaska

Non-custodial parent's adjusted annual net income
Number of children requiring support
Health insurance costs for the children
Work-related child care costs
Custody arrangement (primary vs. shared)
Other child support obligations

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

Alaska Child Support FAQ

How is child support calculated in Alaska?
Alaska uses a modified Percentage of Income model. Child support is calculated as a percentage of the non-custodial parent's adjusted annual net income: 20% for 1 child, 27% for 2 children, and 33% for 3 children. Adjusted net income is gross income minus taxes, Social Security, Medicare, mandatory retirement, and prior child support obligations.
What percentage of income is child support in Alaska?
In Alaska, child support is 20% of adjusted annual net income for 1 child, 27% for 2 children, and 33% for 3 children. These percentages are applied to the non-custodial parent's income after allowable deductions. For more than 3 children, the court uses discretion guided by Alaska Rule of Civil Procedure 90.3.
How does shared custody affect child support in Alaska?
Alaska applies a shared custody adjustment when each parent has physical custody of the children for more than 30% of the year. In shared custody situations, the court calculates each parent's obligation and offsets them, with the higher-earning parent typically paying the difference. This reflects both parents' direct costs during their parenting time.
What deductions are allowed for Alaska child support?
Alaska allows deductions for federal and state income taxes, Social Security taxes, Medicare taxes, mandatory retirement contributions, union dues, child support for prior-born children, and voluntary retirement contributions up to 7.5% of gross income. These deductions are subtracted from gross income to arrive at adjusted annual net income.
How long does child support last in Alaska?
In Alaska, child support generally continues until the child turns 18, or until age 19 if the child is still attending high school. Support may also be ordered for adult children with disabilities. Alaska courts do not typically order support for college expenses unless the parents agree.
