New York Income Withholding For Support (Non-IV-D b) is a process in which an employer is legally obligated to withhold money from the wages of an employee to be used towards child support payments. Non-IV-D b stands for Non-Interstate/Intergovernmental income withholding. This type of income withholding is used when the child support order does not involve two states or the federal government. There are two types of New York Income Withholding For Support (Non-IV-D b): 1. New York State Income Withholding for Support (Non-IV-D b): This type of income withholding is used when the child support order was issued in New York State. 2. New York Out-of-State Income Withholding for Support (Non-IV-D b): This type of income withholding is used when the child support order was issued by a state other than New York.
