Dear Liz: Recently someone wrote to you about plans to receive a state pension and apply for Social Security benefits. You said if the person’s job didn’t pay into Social Security, the Social Security benefit might be reduced because of the state pension. I have a state pension from a job that did not pay into Social Security and was under the impression that I would not be eligible for Social Security benefits. Am I wrong about that?

Answer: If you previously worked at a job that paid into Social Security, you may be able to receive both your state pension and a Social Security retirement benefit. Your Social Security benefit is typically reduced, but never eliminated, because of pensions received from jobs that didn’t pay into the system.

This reduction, known as the windfall elimination provision, does not apply to people who worked for 30 years or more in jobs that paid into Social Security. Its effect is greatest on people who worked less than 20 years in such jobs. Between 20 years and 30 years, the impact declines year by year.

Your state pension also affects — and can eliminate — any spousal or survivor benefits you might have received based on a current or former spouse’s Social Security work record. This separate provision is known as the government pension offset. You can learn about both the windfall elimination provision and government pension offset on the Social Security site, www.ssa.gov.
