The child support definition generally includes all gross income from every source. Instead of arguing whether something is gross income, argue whether or not including the income is fair or unfair. The payor has the burden to argue when the percentage is unfair. In the past the court has affirmed including trips paid by the employer as gross income; health insurance premiums, voluntary contributions to retirement plan; loan repayments from closely held businesses over time; and lump sum retirement benefits. However, gross income does not include public assistance including supplemental security income, educational grants and loans, AFDC and other child support.
