Contribution Rates

Recommended employer contribution rates are determined by KRS' independent actuary based on data in the annual actuarial valuation. The Board of Trustees adopts employer contribution rates necessary for the actuarial soundness of KRS as required by Kentucky Revised Statutes 61.565 and 61.702. KERS and SPRS employer rates are subject to approval by the Kentucky General Assembly through the adoption of the biennial Executive Branch Budget. The Board also 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 KRS.

KRS 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 KRS.  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.

The 2020 Regular Session adjourned Sine Die on April 15, establishing contribution rates effective July 1, 2020. Please note that the General Assembly would typically approve a State Executive Branch budget for the two-year period beginning on July 1, 2020 and extending through June 30, 2022 (fiscal years 2021 and 2022).  However, due to the COVID-19 crisis, the legislature only proposed a one-year budget. A budget for fiscal year 2022, establishing contribution rates effective July 1, 2021, will have to be introduced in a later Session.  

Contribution rates for fiscal year 2021 were impacted by Senate Bill 249. Please refer to our legislative updates for comprehensive information about legislation passed during the 2020 Regular Session.
