The court uses a standard guideline to calculate what the noncustodial parent will pay, based on the noncustodial parent's adjusted gross income and on the number of children involved. The court first determines the noncustodial parent's gross income, and then makes certain deductions (including Medicare, Social Security, and New York City or Yonkers tax) to establish the noncustodial parent's adjusted gross income. The court then multiplies the adjusted gross income by the standard guideline percentage for the number of children. These percentages are as follows:
•17% for one child
•25% for two children
•29% for three children
•31% for four children
•at least 35% for five or more children.
Then the noncustodial parent's share of child care, medical, and educational expenses is added to the income percentage amount. The combined amount, percentage of income plus share of expenses, is the basic child support amount.
For incomes over $130,000, the court determines whether or not to use the percentage guidelines and may consider other factors in setting the full child support payment.
