Vesting (Pension)
The point at which a government employee has earned the right to receive a pension benefit, even if they leave before retirement. Typically requires 5-10 years of service.
How It Works
Vesting is the point at which an employee's rights to employer-funded pension benefits become non-forfeitable. Before vesting, an employee who leaves typically receives only a refund of their own contributions plus minimal interest, forfeiting the entire employer match. After vesting, the employee is entitled to a deferred pension benefit payable at retirement age, calculated on years of service and final salary at departure. Vesting periods for public DB plans typically range from 5 to 10 years: CalPERS vests at 5 years, Illinois Municipal Retirement Fund at 8 years (for Tier 2 hired after 2011), Massachusetts State Retirement at 10 years. For DC plans under IRC Section 401(a), vesting schedules can range from immediate to 5-year graded vesting. The vesting cliff creates a strong retention incentive: employees approaching their vesting date face a large financial penalty for leaving, contributing to the "golden handcuffs" effect documented by economist Maria Fitzpatrick. Several pension reforms have lengthened vesting periods for new employees as a cost-saving measure. Illinois Tier 2 (post-2011) employees face a 10-year vesting period and reduced benefits compared to Tier 1. Rhode Island's 2011 Employee Retirement Income Security Act extended vesting and moved employees to hybrid plans. Longer vesting periods generate actuarial savings for the plan because some employees will leave before vesting, forfeiting employer-funded benefits, but they also complicate hiring for public employers competing with private-sector firms that offer immediate 401(k) vesting. The National Association of State Retirement Administrators (NASRA) publishes annual surveys of vesting rules across all major public plans. Vesting policy feeds indirectly into the 20% pension funding factor of the CitySpend Fiscal Health Score through its effect on long-term liability accumulation.
