At the time of retirement on annuity, a deputy sheriff  who is a member of the County Police Department, who chooses to retire  under provisions of this Article other than Section 9-128.1, may receive a  refund of the difference between the contributions made as a deputy sheriff  who is a member of the County Police Department and the contributions that  would have been made for such service not as a deputy sheriff who is a  member of the County Police Department, including interest earned.Such deductions beginning on the effective date and prior to July 1,  1947 shall be made and continued for a future entrant while he is in the  service until he attains age 65, and beginning on the effective date and  prior to July 1, 1953 for a present employee while he is in the service  until the amount so deducted from his salary or paid by him according to  law to any county pension  fund in force on the effective date, with interest on both such amounts  at 4% per annum, equals the sum that would have been to his credit from  sums deducted from his salary if deductions at the rate herein stated  had been made during his entire service until he attained age 65, with  interest at 4% per annum for the period subsequent to his attainment of  age 65. Such deductions beginning July 1, 1947 for future entrants and  beginning July 1, 1953 for present employees shall be made and continued  while such future entrant or present employee is in the service.(b) Concurrently with each employee contribution, the county shall  contribute beginning on the effective date and prior to July 1, 1947, 5  3/4%, and beginning on July 1, 1947 and prior to July 1, 1953, 7%; and  beginning on July 1, 1953, 6% of each payment of such salary until the  employee attains age 65.(c) Each present employee contribution made prior to the date the  age and service annuity for such employee is fixed, each future entrant  contribution, and each corresponding county contribution shall be  allocated to the account of and credited to the employee for whose  benefit it is made.
