Contribution Rates

Each employer is required to contribute at the rate determined by the Board of Trustees to be necessary for the actuarial soundness of KRS as required by law.  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 exempt from Federal and State Income Tax withholding.  Mandatory employee contributions have been exempt from Federal and State Income Tax withholdings since August 1, 1982.  These contributions are tax deferred, which means the contributions are withheld from employees’ gross pay before Federal and State Income Tax. 

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, employee contributions are deducted after Federal Social Security is withheld.
