Do you have a federal or local government pension? Don’t let the WEP or GPO surprise you. The Windfall Elimination Provision and Government Pension Offset, often called the WEP and GPO, are two rules that can leave you scratching your head. Not only do many people find these rules confusing, but they are also often completely overlooked, which may result in a big surprise when filing for Social Security benefits. Unfortunately, this is not one of those good surprises.

What are the WEP and GPO?

The WEP reduces a worker’s own Social Security benefit while the GPO reduces spousal and survivor benefits received from another’s work record, such as a spouse.

Who is affected?

The WEP and GPO affect individuals who qualify for a pension from non-covered (did not pay Social Security tax) employment. These are typically your federal and local government workers, such as teachers, police officers, and firefighters. Whether these jobs are non-covered will depend on the state/employer. Overseas employees may also fit under this category.

For the WEP to apply, the individual must have an additional job with covered earnings (did pay Social Security tax) that qualifies them for Social Security benefits. Thus, the WEP applies to those who have a mix of covered and non-covered employment. Specifically, they qualify for Social Security benefits and receive a non-covered pension. The GPO applies when an individual with a non-covered pension receives a spousal or survivor benefit. Are you scratching your head yet?

WEP example:

Dan works as a public school teacher in California, one of 15 states where teachers do not pay Social Security tax. He qualifies for a pension through the California State Teachers’ Retirement System (CalSTRS). To make extra money for his household, Dan works an additional job during the summer, where he does pay Social Security tax. By the end of his career, he has worked enough summers to qualify for a Social Security benefit. The WEP will reduce Dan’s benefit since he has both a non-covered pension from his career as a teacher and qualifies for Social Security benefits from his summer job.

How will the WEP affect my benefit?

Understanding the details of the WEP is quite complicated. To simplify, the WEP tweaks the Social Security benefit formula, resulting in a reduction of the worker’s Primary Insurance Amount (PIA). The PIA is the benefit amount one would receive at full retirement age. The amount reduced depends on the number of years with “substantial earnings” in covered employment. The Social Security Administration provides the WEP Chart as a reference to understand the potential benefit reductions based on the number of years of substantial earnings. The maximum monthly reduction is capped at $480 in 2020. The amount reduced stays constant for the first 20 years of substantial earnings before decreasing incrementally per year until it is completely eliminated upon reaching 30 years of substantial earnings.

This offers an incredible planning opportunity for those who have already accumulated a number of years of substantial earnings. If you are thinking of retiring and have accumulated 20 years of covered work, it could make a lot of sense to work for ten more years to eliminate the WEP completely. Remember, you only need to have substantial earnings, so part-time work would count as long as you make what is deemed “substantial” in that year. For someone subject to the full WEP reduction and assuming a 20-year retirement, it could be worth more than $100,000.

It is important to note that the reduction is limited to one-half of an individual’s non-covered pension. This primarily comes into play when the majority of an individual’s earnings are in covered employment but have a small non-covered pension. For example, if you had a pension of $600 per month and your Social Security benefit was $1,200 per month, your benefit will not be reduced by more than $300 (half of your pension income).

How will the GPO affect my benefit?

This rule is more straightforward to understand than the WEP. The GPO will reduce an individual’s spousal or survivor benefit by two-thirds of their non-covered pension benefit.

GPO example:

Sarah qualified for a pension of $2,100 per month from a government job. Her husband, Drew, worked as an engineer for a large corporation. Drew applied for his Social Security benefit at his full retirement age and receives $2,600 per month. Sarah applies for a spousal benefit once she reaches full retirement age. This benefit would generally be $1,300 (50% of her spouse’s); however, the benefit is reduced by two-thirds of her non-covered pension. In this case, she would not receive anything since two-thirds of her pension ($1,400) is greater than what her spousal benefit would be.

Let’s say Drew passed away unexpectedly. Sarah would normally qualify for a survivor benefit equal to Drew’s entire benefit of $2,600. Because of the GPO, she will only receive $1,200 since the benefit would first be reduced by two-thirds of her pension ($2,600 – $1,400).

Keep in mind the GPO only applies to the individual’s own non-covered work. If a surviving spouse is a beneficiary of a non-covered pension, their Social Security benefits will not be reduced.


These rules are tricky to navigate and important to understand for those affected. What makes it worse is that your Social Security statement will not reflect the reduction in benefits from the WEP and GPO. This means it requires work and effort on your part to figure out! The Social Security Administration has provided an online WEP and GPO calculator to help with this. It will ask for a birthdate, non-covered pension benefit amounts, and other relevant information to calculate your new benefit factoring in the rule. If you have a family member or friend with a non-covered pension, they may be subject to these two rules. Please forward this on to them or anyone else who may find it useful.
