Open Enrollment

Open Enrollment is your one time of the year to verify your personal benefits information, make any changes you wish to your plan elections, enroll in a flexible spending account (FSA) and add or remove dependents.
Enrollment requires using Employee Self-Service (ESS).You may also log in to ESS from a computer outside of the County's network. Required documentation must be scanned and uploaded to ESS in order to complete enrollment for dependents. For assistance with logging into ESS, please contact your agency's Help Desk.
Online Open Enrollment Assistance
If you need assistance with enrollment, schedule an one on one appointment with a member of the Employee Benefits staff. If you need to cancel your appointment, please notify our office through email risk.mgmt@cookcountyil.gov.

REMEMBER: Any changes you make to plan elections during the Open Enrollment period go into effect the start of the new plan years (December 1st for all benefits except FSA, which is January 1st). If you enroll in the health care or dependent care FSA, deductions will begin with the first pay check of the calendar year.
