The state’s Equal Pay Registration Certificate requirements of the Equal Pay Act will take effect March 24, 2022, according to the Illinois Department of Labor (IDOL). A number of employers have received IDOL notices that they were selected for the first registration deadline: May 25, 2022.

Illinois requires businesses with more than 100 employees to obtain from the IDOL an equal pay registration certificate certifying compliance with the Equal Pay Act. To obtain the certificate, businesses will have to provide workforce compensation data to the IDOL and affirm compliance with several federal and state pay equity statutes.

The IDOL announced that businesses will receive notification of their registration deadline no less than 120 days before their assigned deadline. The assignment of deadlines is ongoing, and the IDOL said that some businesses may not receive their assigned registration deadline for over a year.
