Open Enrollment

Annual Open Enrollment allows you to review and change your benefit options to ensure that you are choosing the best combination of benefits for you and your family.

Open Enrollment for the 2026 plan year took place in October 2025. Changes made to your benefits for the 2026 plan year during Open Enrollment became effective January 1, 2026.

The 2027 plan year Open Enrollment will be “passive,” meaning the benefits you currently have will continue into 2027 if you do not make any changes, except for voluntary contributions to your Flexible Spending Accounts (FSAs). FSA's must be reelected annually during Open Enrollment if you wish to participate in the new plan year.

If you wish to make changes to your benefit selections, or you wish to participate in an FSA for the 2027 plan year, you must complete and submit enrollment selections through PeopleSoft Self Service during the Open Enrollment period. Be on the lookout for an email from CountyBenefits@stancounty.com
