Recommended employer contribution rates are determined by the annual actuarial valuation and presented to the Board of Trustees for approval. Actual employer contribution rates are set by the General Assembly in the biennial budget. Each employer is required to contribute at the rate set by law. Please note that employer contribution rates are subject to change depending on future actions of the General Assembly. Employer contributions are paid on creditable compensation earned by each employee eligible for membership in KRS. 

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.

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

Please keep in mind that the General Assembly establishes the final KERS and SPRS rates in the biennial executive branch budget bill.  Fiscal Year 2021 employer contribution rates are subject to change depending on future actions of the General Assembly.
