How New Jersey works it out

New Jersey uses the income shares model: the parents’ combined weekly net income sets a basic amount from the schedule, and each parent owes their share of it by income.

The guidelines work on weekly net income. Taxes come from the official combined withholding tables (federal, state, Social Security and Medicare), and the parent the children live with mostly claims them as dependents. Monthly amounts are divided by 4.3 to get weekly amounts.

The parent the children don’t live with mostly gets a credit for 37% of the basic amount times their share of overnights. From 28% of overnights (101 a year) the shared parenting worksheet also counts the fixed costs of a second home. If the primary household’s income would fall below twice the poverty guideline, the sole worksheet is used instead.
