2026 Vendor Change: FSA, HSA, Parking & Transit Accounts

The Flexible Spending Account (FSA) and Health Savings Account (HSA) vendor will change effective January 1, 2026. This web page will be continuously updated with information about the transition.

Summary

Total Administrative Services Corporation (TASC) is the new third-party administrator for the FSA, HSA, and Parking & Transit Accounts effective January 1, 2026. This change was approved by the Group Insurance Board (GIB) early 2025. Below is a list of the affected accounts.

  • Health Care Flexible Spending Account (FSA)
  • Limited Purpose Health Care FSA
  • Dependent Day Care Account
  • Health Savings Account (HSA)
  • Parking & Transit Accounts

Optum will no longer be the third-party administrator after December 31, 2025. However, health care FSA claims incurred for the 2025 plan year must be substantiated with Optum by March 31, 2026. To avoid the payroll withholding process, participants should resolve their unsubstantiated claims with Optum by December 31, 2025.
