Okla. Stat. tit. 19 § 954
It shall be the mandatory duty of the board of county commissioners of any county establishing a retirement fund and system to appropriate annually, for the sole use of the retirement fund within its general fund and subject to the approval of the county excise board, a sum which shall be equal to or exceed the contributions made to the retirement fund by the employees. Such appropriation shall not exceed the sum of the current annual salaries of all employees to be covered in the following percentages:
July 1, 2007 - June 30, 2008 | 13 1/2% |
July 1, 2008 - June 30, 2009 | 14 1/2% |
July 1, 2009 - June 30, 2010 | 15 1/2% |
July 1, 2010 - June 30, 2019 | 16 1/2% |
July 1, 2019 - June 30, 2020 and each year thereafter | 18 1/2% |
Beginning July 1, 2019, the total employer and employee contributions shall not exceed eighteen and one-half percent (18.5%) of the monthly compensation of each member. The governing body of the participating employers listed in this section may vary the percentage contribution of the employer and employee, provided the total percentage contributed by the employer and employee equals the total percentage contribution required by this section. Payment of such shall be paid to the fund upon verified claims by the treasurer of the fund approved by the board of trustees and attested by its clerk. For any contribution made on or after July 1, 2021, to June 30, 2022, of less than eighteen and one-half percent (18.5%), an employer may retroactively make a one-time lump sum contribution of an amount equal to the difference between the actual total contribution that was made and the total contribution amount equal to eighteen and one-half percent (18.5%).
