12. State-Specific Notes

1. Melson Formula: Hawaii uses the Melson Formula, which is a variation of the Income Shares Model. Only Delaware, Hawaii, and Montana use this approach.

2. Net Income Basis: Hawaii calculates based on net income after taxes and social security deductions, not gross income.

3. Self-Support Allowance: The formula ensures each parent retains enough income for basic living needs before child support is calculated, based on the Hawaii federal poverty level.

4. SOLA Percentages: The Standard of Living Adjustment is 10% per child, capped at 30% for three or more children.

5. High Cost of Living: Hawaii's cost of living is significantly higher than the mainland U.S. The guidelines account for this through the PCSN base amounts tied to the Hawaii federal poverty level.

6. Inter-Island Travel: Travel costs for visitation between Hawaiian islands or to/from the mainland may be considered as an extraordinary expense or deviation factor.

7. Military Presence: Hawaii has a significant military population. Military pay (including allowances) is generally included in income, though specific housing allowances may be treated differently.
