Contribution Rates


Recommended employer contribution rates are determined by KPPA's independent actuary based on data in the annual actuarial valuation. The County Employees Retirement System (CERS) and the Kentucky Retirement Systems (KRS) Boards of Trustees adopt employer contribution rates necessary for the actuarial soundness of the systems governed by the respective boards as required by state law. The Kentucky Employees Retirement System (KERS) and State Police Retirement System (SPRS) employer rates are subject to​ approval by the Kentucky General Assembly through the adoption of the biennial Executive Branch Budget. The CERS Board sets CERS contribution rates, unless altered by legislation enacted by the General Assembly.

Each employer is required to contribute at the rate set by law. Employer contributions are paid on creditable compensation earned by each employee eligible for membership in the systems operated by KPPA. KERS Nonhazardous employer contributions include an additional amount based on unfunded liability.

KPPA provides information for GASB 68 and GASB 75 reporting, including the pension and insurance components of employer contributions. Learn more on the GASB Overview page.

Employee Contributions

All employees meeting the requirements for membership are required to contribute a percentage of their gross wages, referred to as creditable compensation, to KPPA. The percentage contributed is set by state law based on the member's benefit tier. 

When mandatory employee contributions are deducted from an employee's check, the contributions are tax deferred. This means the contributions are withheld from employees' gross pay before Federal and State Income Tax. Mandatory employee contributions have been exempt from Federal and State Income Tax withholdings since August 1, 1982.  

From January 1, 1987 through December 31, 2016, Federal Social Security withholdings were also exempt. This changed January 1, 2017 under a Memorandum of Agreement between the Commonwealth of Kentucky and the Internal Revenue Service. As of January 1, 2017, the employee contribution is still based on the total gross salary for the pay period, but should be deducted after Federal Social Security is withheld.​

Employer Contributions

The 2021 Regular Session of the Kentucky General Assembly adjourned sine die on March 30, 2021, establishing contribution rates effective July 1, 2021. Due to the COVID-19 crisis, the legislature passed a one-year budget during the 2020 Regular Session rather than the customary two-year budget. Therefore, the General Assembly passed House Bill 192 during the 2021 Session that will cover Fiscal Year 2022.​

The KRS Board of Trustees is required by law to determine the employer contribution rates for KERS and SPRS based on an annual actuarial valuation. The most recent actuarial valuations were performed by the system's actuary, Gabriel Roeder Smith & Company (GRS), for the fiscal year ended June 30, 2021.

At the December 2, 2021 meeting, the KRS Board of Trustees approved the recommended contribution rates for fiscal year 2022-2023 and 2023-2024.

Please keep in mind that the General Assembly establishes the final rates in the biennial executive branch budget bill. Employer contribution rates are subject to change depending on future actions of the General Assembly.

**Pursuant to KRS 61.565, each participating KERS Nonhazardous employer is required to pay off its own portion of the total KERS Nonhazardous unfunded liability over a set period regardless of covered payroll. Each KERS Nonhazardous employer will pay the normal cost contribution rate and pay a dollar amount each month representing their share of the unfunded liability. ​​

​KERS Nonhazardous Actuarial Accrued Liability Contribution Payments

Pursuant to Kentucky Revised Statute (KRS) 61.565, the method of calculating the KERS Nonhazardous employer contribution changed from a percentage of pay to a two-part calculation. Beginning with Fiscal Year 2022, the law requires that each KERS Nonhazardous employer pay its own portion of the total KERS Nonhazardous unfunded pension liability, regardless of covered payroll, and that the employer complete an annual certification of non-contributing service providers.
