Combined service annuity requirements modified.

This bill modifies the rules for receiving a combined retirement annuity in Minnesota by updating the eligibility requirements and calculation methods for employees with service in multiple state retirement plans. To qualify, individuals must have at least half a year of service in each plan, a total service record meeting the longest vesting requirement among them, and must retire within a one-year window after starting benefits in any of those plans. The legislation establishes new formulas for combining service credits, caps accrual rates for specific plans, and clarifies how early retirement benefits apply to teachers and other public employees. These changes are effective immediately upon the bill's final passage and apply only to those whose public service ended on or after May 1, 1975.
