Tier 1 vs. Tier 2 Pensions
On January 1, 2011, the Illinois legislature established two sets of pension eligibility requirements. Members who joined CTPF or a qualified reciprocal system prior to January 1, 2011, are Tier 1. Members who joined CTPF on or after January 1, 2011, are Tier 2.
The pension calculation for both tiers is the same, but the retirement age and method for calculating the final average salary are different. Additionally, the salary used in the calculation of a pension is capped for Tier 2. The Tier 2 salary cap does not limit how much can be earned; it limits the amount for which pension contributions are made.
The chart below summarizes the differences in calculating benefits for Tier 1 and Tier 2 employees.
