Oklahoma

Overview

Oklahoma sponsors six state retirement systems: the Teachers’ Retirement System of Oklahoma; the Oklahoma Public Employees’ Retirement System; the Oklahoma Firefighters Pension and Retirement System; the Oklahoma Police Pension and Retirement System; the Oklahoma Law Enforcement Retirement System; and the Wildlife  Conservation Retirement Plan.

OK PERS administers retirement benefits for employees of the state and political subdivisions that have elected to participate, who are not eligible to participate in another system. Each retirement system is responsible for managing its own assets.

Some political subdivisions sponsor their own retirement system, including Oklahoma County, Tulsa County and Oklahoma City and the City of Tulsa.

Plan Design

Most public employees in Oklahoma participate in a traditional defined benefit plan. Exceptions are state employees hired since November 2015 and employees of the Wildlife Conservation Retirement Plan hired since July 2010, who participate in a defined contribution plan as their primary retirement benefit.

According to the US Government Accountability Office, 92 percent of employees of state and local government in Oklahoma participate in Social Security.
