Yes, for all income withholdings, the upper limit on what may be withheld is based on the Federal Consumer Credit Protection Act (CCPA). The federal withholding limits for child support and alimony are based on the disposable earnings of the employee.
The Federal CCPA limit is 50 percent of the disposable earnings if the employee supports a second family and 60 percent if the employee does not support a second family. These limits increase to 55 percent and 65 percent respectively if the employee owes arrearages that are 12 weeks or more past due.
