The Government Pension Offset (GPO) was repealed by the Social Security Fairness Act (signed January 2025), effective for benefits payable for January 2024 and later. No offset applies — you receive your full spousal or survivor benefit.

How It Works

For workers with a government pension, the Government Pension Offset can quietly shrink the spousal or survivor Social Security benefits they were counting on. This tool estimates that reduction, which matters for retirement planning because it can reshape your expected income, particularly given the 2026 maximum GPO reduction. The offset can claim up to two-thirds of your government pension, trimming your Social Security spousal or survivor benefit dollar-for-dollar.

Mechanically, the GPO subtracts two-thirds of the monthly government pension you earned without paying Social Security taxes from your spousal or survivor benefit. That step comes before other deductions, including the Windfall Elimination Provision (WEP), which works on your own earned Social Security benefits instead. The formula reads: Reduced Social Security Benefit = Unadjusted Social Security Benefit - (2/3 * Monthly Government Pension).

Two misreadings are worth heading off. The GPO does not touch every government pension, only those tied to work where you paid no Social Security taxes. And while it can drive a spousal or survivor benefit all the way to zero, it cannot reduce the Social Security benefit you earned through your own covered work. Because the rules run deep and exceptions exist, confirm how they apply to your own record with the Social Security Administration.

Example: Maria's GPO Calculation

  1. 1 Maria receives a monthly government pension of $1,500 from a job where she did not pay Social Security taxes. She is also eligible for a spousal Social Security benefit of $1,000 per month based on her husband's earnings record.
  2. 2 The GPO reduction is calculated as two-thirds of her government pension: (2/3) * $1,500 = $1,000.
  3. 3 Maria's spousal Social Security benefit will be reduced by $1,000. Therefore, her adjusted spousal Social Security benefit will be $1,000 - $1,000 = $0 per month.
  4. 4 In this scenario, Maria's government pension completely offsets her spousal Social Security benefit. This example highlights how significantly the GPO can impact expected benefits, making accurate planning essential for those affected.

Frequently Asked Questions

What is the Government Pension Offset?
The GPO reduces Social Security spousal or survivor benefits for anyone who receives a government pension from work not covered by Social Security. The reduction is two-thirds of your government pension amount. It can completely eliminate the spousal or survivor benefit.
How much does GPO reduce my benefits?
The GPO offset is exactly two-thirds of your government pension. If your government pension is $3,000/month, the GPO offset is $2,000. If your spousal SS benefit would be $1,500, the GPO completely eliminates it ($1,500 - $2,000 = $0). You cannot receive a negative amount.
Is there any way to avoid GPO?
GPO does not apply if you paid Social Security taxes during your last 60 months of government employment. Some government employees who switched to FERS (which covers Social Security) in their final 5 years may avoid GPO. Legislative proposals to repeal GPO are periodically introduced but have not passed.
