The Department will determine which claimed expenses are deductible and their amounts.
For households with a history of three or more months of paying child support, average at least three months' payments (including arrearages), taking into account any change in the legal obligation, and use this average as the household's support deduction.
For households with either no or less than a three-month child support payment history, estimate the anticipated payments (excluding arrearages) and use this estimate as the household's support deduction.
