Social Security Offset

In Detail

A Social Security offset is a plan feature that reduces pension benefits by some portion of the participant's Social Security benefit. The rationale is that the pension and Social Security together should provide a target retirement income, so the pension payment decreases as Social Security provides more. For example, a plan might target 70% income replacement, providing whatever amount is needed above Social Security to reach that target. Offset plans were more common in past decades and have become controversial because they can significantly reduce pension benefits, particularly for lower-paid workers who receive a higher percentage of their salary from Social Security.

Some plans use an "integrated" or "permitted disparity" approach rather than a direct offset, providing higher benefit accrual rates on earnings above the Social Security taxable wage base. It is important for participants in offset plans to understand that their pension benefit alone may be less than expected, and that the offset typically applies at retirement regardless of whether the participant actually claims Social Security at that time. Government employees in some states do not participate in Social Security at all, which means offset provisions are irrelevant, but they may face the Windfall Elimination Provision (WEP) if they also have Social Security credits from other employment.
