CSRS and Social Security


Q. I am a federal employee with 42 years of CSRS service. Will I be afforded the opportunity to receive Social Security benefits when I reach the age of 65?

A. You would only be entitled to a Social Security benefit if you had worked outside the government and earned at least 40 Social Security credits. However, because you worked under CSRS – a retirement system where Social Security taxes weren’t deducted from your wages – you’d be subject to the windfall elimination provision of law. The WEP would reduce that benefit unless you had at least 30 years of substantial earnings under Social Security.

  1. I,m retired on CSRS Disability, I,m 68 and wanting to collect SS,,, I have more than 40 quarters… I went on CSRS in 1993….When I apply for SS will I be subject to the special eroll ment penalty under medicare. I,ve had the VA medical insurance this whole time….I understand I will automatically receive part A , but will I be penalized for part B for not signing up at 65….Also, what about WEP AS mentioned I retired from CSRS in 1993 on disability and have work under SS thruout the 70,s 80,s till 1993

    • Yes, you will be penalized for not having enrolled in Medicare Part B during the initial enrollment period, which runs from 3 months before someone turns 65 and ends three moths after that month. As you noted, you are automatically eligible for Medicare Part A at no expense to yourself. As for the windfall elimination provision, your Social Security benefit will be reduced – but not eliminated – if you have fewer than 30 years of substantial earnings under Social Security. The “substantial earnings” criterion is higher than that required to earn a year of Social Security credit. For example, in 2020, you’d only have to earn $5,640 to received 4 Social Security credits; however, for those earnings to be considered substantial, you’d have to earn $25,575 during the year.

  2. I am a retired CSRS employee. I have worked in the private sector and have 30 quarters towards Social Security.If I work and earn the remaining 10 quarters now that I have retired will I be subject to the WEP ?

  3. I am a CSRS employee, I have been for 42 years this coming February 2021. My question is: If my husband passes away before I do, and when I retire, will I be able to draw anything from his retirement?

    • You would be entitled to any survivor annuity based on your husband’s employment history. However, any spousal Social Security benefit to which you’d otherwise be entitled would be subject to the government pension offset provision of law. The GPO would reduce or eliminate than benefit.
