Child care for work or training and the children's health insurance are part of the primary need, so they are shared by net income; the parent who pays them gets credit.
How Hawaii works it out
Hawaii uses a Melson-type formula. The children's primary need ($455 a child plus child care and health insurance) comes first; a standard of living adjustment then shares part of the parents' remaining income with the children. Each parent's part follows their share of the parents' combined net income.
Gross income from almost all sources counts. Net income comes from the Table of Incomes: gross income minus income taxes and Social Security and Medicare at the rates the guidelines fix, minus a $1,693 self-support reserve, so it is not take-home pay. Spousal support paid is subtracted from gross income and support received is added.
When the parent with fewer overnights has more than 143 a year, the extensive time-sharing worksheet lowers that parent's amount for each extra overnight. With equal time each parent's amount is counted for half the year and the parent who owes more pays half the difference.
