The Illinois Order/Notice to Withhold Income for Child Support (TWO) is a form issued by the Illinois Department of Healthcare and Family Services (HFS) to employers, banks, and other income withholding sources. It is a legal document that instructs the withholding source to take a specified amount of money from the non-custodial parent’s income and send it to HFS to be used for child support payments. All Twos are issued in accordance with the Illinois Income Withholding for Support Act and the Uniform Interstate Family Support Act. There are two types of Twos: an original order and a modification order. An original order is issued when a new child support obligation is established or an existing obligation is modified. A modification order is issued when an existing TWO has been updated or amended. Both orders must be served on the employer or other withholding source within 14 days of the date of issuance. The employer is then required to begin withholding from the non-custodial parent’s income within 10 days of service of the order. The TWO is an important tool used by the HFS to ensure that child support payments are made on time and in full. It is important that employers, banks, and other income withholding sources comply with the TWO to ensure that the children receive the support they are entitled to.
