Service Information


OPEN ENROLLMENT - Plan Year 2023

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.

If you wish to participate in a FSA for the 2023 plan year, you MUST enroll during Open Enrollment. Payroll deductions will be taken over 26 pay periods. Remember: FSA enrollment does not roll over from year to year.

Open Enrollment is only available October 1st through October 31st, so please be sure to make changes to benefits elections for you and your dependents during this time.

If you miss this window of opportunity, the only changes you will be able to make to your current benefit elections will be in conjunction with a "qualifying life event" like marriage or the birth of a child.

    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.
