An Illinois Wage Deduction Notice is a document that employers are required to give to employees prior to any deductions from their wages. There are two types of Illinois Wage Deduction Notice: a Wage Deduction Authorization Form and a Wage Deduction Notice. The Wage Deduction Authorization Form allows employers to make deductions from an employee's wages for items such as health insurance premiums, loan repayments, or other deductions that are required by law. The Wage Deduction Notice provides information about the wage deduction, such as the amount, pay period, and how the deductions will be taken from the employee's pay. Both forms are required by the Illinois Department of Labor.
