11. State-Specific Notes

1. Percentage of Income Model: Alaska uses a Percentage of Income model focused primarily on the noncustodial parent's income, unlike Income Shares states that combine both parents' incomes.

2. Income Cap: The standard calculation applies to the first $138,000 of adjusted annual income. Income above this threshold requires separate evidence and court determination.

3. Permanent Fund Dividend: The Alaska Permanent Fund Dividend is included in gross income for child support calculation purposes.

4. Shared Custody Threshold: Shared custody provisions apply when each parent has physical custody for at least 30% of overnights annually (approximately 110 nights).

5. Military Allowances: Non-housing military allowances (BAS, COLA, hazard pay) are included in gross income. BAH is generally excluded.

6. Legislative Changes: The Alaska Legislature has considered revisions to Rule 90.3 (see SB 46). Practitioners should verify current rule status.
