Illinois law requires private businesses with 100 or more employees in the State of Illinois to submit an application to obtain an Equal Pay Registration Certificate (EPRC) by providing certain pay, demographic, and other data to the Illinois Department of Labor (IDOL) by March 24, 2024, and to recertify every two years after the first submission. The law also requires such employers to submit certain information with their application, including: a statement certifying that the business is in compliance with the Equal Pay Act of 2003 and other State and federal laws related to equal pay.
Employers can access the online portal that businesses must use to submit their contact information and required data to IDOL, a training guide for use of the portal, a compliance statement template, and other certification information and resources here. Additionally, the Illinois Department of Labor provides a helpful FAQ.
