To obtain a refund of your contributions after your resignation from service, you must complete a refund application. A copy of your department approved Resignation/Termination Letter, Driver’s License or State I.D. and Social Security Card will be required. Processing of your application will generally take six to eight weeks (after your resignation date), provided all of the necessary paperwork has been received. To request that a refund application be sent to you, please call 312-236-4700. Please note: If you are age 55 or over with 10 years of service, or if you are age 60 or over with any number of years of service, you qualify for a monthly annuity. If your annuity is $800.00 or more per month, you will not be eligible for a refund, but will instead receive a monthly annuity.
