Social Security Questions? Ask a Social Security Expert
When you work for an employer who doesn’t withhold Social Security taxes from your salary, such as a government agency like you, any pension you get from that work can reduce your Social Security benefits.
SSA bases your Social Security benefit on your average monthly earnings adjusted for average wage growth.
A federal worker first hired after December 31, 1983 is not effected by the adjustment.
A pension based on earnings not covered by Social Security can affect the amount of your Social Security benefit this is called Windfall Elimination Provision.
Your federal pension is not effected but your SSA benefits may be.
