The benefit payable to you at retirement is based in part on service credit accrued for the compensable period of time you were an active participant in the system. You also may be able to purchase retirement service credit for previous VCERA retirement system membership, other applicable County service, and eligible public service. Actively employed members and separated vested members may purchase eligible service. Service may not be purchased by separated non-vested or retired members. In instances of disability retirements, purchased service credit may not increase your final retirement benefit; you may contact VCERA for more information regarding this. Only Safety members may purchase service after they have refunded their VCERA retirement accounts (under G.C. 31831.3).
