There are many components that go into the calculation of a child support obligation. Calculating a parent's income for purposes of determining a child support obligation is not as simple as one may think. Pursuant to the Pennsylvania support law, "income" is defined very broadly. The definition, includes, but is not limited to, wages, salaries, bonuses, fees, commissions, interest, rents, royalties, dividends, pensions and all forms of retirement. Also included in "income" is "Social Security disability benefits, Social Security retirement benefits, temporary and permanent disability benefits, workers' compensation and unemployment compensation."
