The Illinois Wage Deduction Notice is a document used to inform employees of a wage deduction that will be made from their paycheck. This notice is required by the Illinois Wage Payment and Collection Act and must be provided to the employee prior to the wage deduction taking place. There are two types of Illinois Wage Deduction Notice: (1) Voluntary Deductions and (2) Mandatory Deductions. The Voluntary Deduction Notice must be signed by the employee and employer and must include the amount of the deduction, the purpose of the deduction, and the date the deduction will be taken. The Mandatory Deduction Notice must be signed by the employer and must include the amount of the deduction, the purpose of the deduction, and the date the deduction will be taken. Both notices must be provided to the employee in writing prior to the wage deduction taking place.
