Death benefits payable to the beneficiaries of deceased IMRF participating (active) members consist of a refund of member contributions including interest, plus a supplemental amount equal to one year’s earnings. The cost of the supplemental portion is borne entirely by the employer . The average death benefit contribution rate for 2025 is 0.12% of participating payroll.
Employer contributions for death purposes are placed in a Death Benefit Reserve for all IMRF employers. However, the assessment to individual employers is on an individual basis, much like a group life insurance premium. The rates are calculated separately for each employer based on the average age of their employees.
