Some considerations that affect a payor’s income as discussed in the Giglio v. Giglio decision are:
1) whether the payor is intentionally underemployed;
2) whether non-salary amounts that the payor receives under a contract be included as income;
3) bonuses and commissions paid through third party payments that should be included in payor’s income; and,
4) personal expenses that the payor has expensed through work be included as income.
