2.4.4 Child Support Income
The child support income of both parents is used to calculate their child support assessment.
A parent's share of the parents' combined child support income indicates the share of the costs of the child they are responsible to meet. This is an 'income shares' approach and treats both parents' incomes in the same way. This section explains how a parent's child support income is calculated and includes information about the rules that apply when income information is not available and when a taxable income is amended.
