4.14 Contribution Rates

Member and employer contributions are a legal requirement for governmental units participating in IMRF. These contributions are calculated as a percentage of monthly wages. Member contributions are a condition of employment for covered employees and should be deducted at the time wages are paid. Failure to make deductions does not release the employer or member from this liability.

If you are not sure whether an employee is covered by IMRF, refer to:

Every year IMRF provides each employer a Final Rate Notice” (Exhibit 4A) confirming the employer and member IMRF contribution rates for the next year. Rate Notices are available online in the Employer Document Archive of Employer Access.
