It only affects you if you will be eligible for a pension that is based on earnings that were not covered under the Social Security system. In this situation the Government Pension Offset rule may reduce the Social Security benefits you are eligible to receive as a spouse, ex-spouse or as a widow/widower. (Benefits you are eligible to receive based on your own earnings record may be affected by the Windfall Elimination Provision (WEP).)
The Government Pension Offset (GPO) rule most commonly affects teachers, law enforcement workers, postal workers, fire fighters and other government employees who work for an entity that has their own pension system and does not participate in the Social Security system. It can also affect you if you receive a pension based on work done outside of the country.
Normally, particularly for married couples, there are Social Security strategies you can use, such as one spouse claiming a spousal benefit at their full retirement age, then switching over to their own benefit when they reach 70. If the Government Pension Offset or Windfall Elimination Provision affects you and/or your spouse, these strategies have to be carefully evaluated in light of the effects of these rules.
Why is the Government Pension Offset Rule in Place?
The Government Pension Offset page of the Social Security website answers the question as to why your benefits will be reduced, and provides additional details on this provision of Social Security.
How Much Might My Spousal or Widow/Widower Benefits Be Reduced By The Government Pension Offset?
Your Social Security benefits will be reduced by two-thirds of the amount of the qualifying pension. (In some cases you may also receive a pension from an employer where the work was covered under Social Security. That pension does not affect your Social Security benefits.)
If you will receive a pension of $900 that is from years of work that were not covered under Social Security than two-thirds of this amount (or $600) will be deducted from the spousal or widow/widower benefit that you would have otherwise received. If you were also eligible for a $1,600 widow/widower benefit, in this situation your widow/widower benefit would be $1,000 instead of the $1,600.
How Do I Estimate My Benefits if GPO Applies to Me?
There are several online Social Security calculators that will calculate your benefits after the relevant impact of the Government Pension Offset or Windfall Elimination Provision. In order to do this you have to input your earnings history and pension estimates into the software. Several of the software packages are then designed to produce a claiming recommendation for you based on your personal situation.
As you near retirement you can also ask the Social Security office to prepare an estimate for you that includes the effects of provisions like GPO and WEP. Be prepared to have to wait in the Social Security office for quite some time, or spend a substantial amount of time on the phone with them to get the information you need. With about 10,000 people a day turning 62, Social Security offices and representatives are often overwhelmed with work.
