What the WEP and GPO do to your Social Security payment

The Windfall Elimination Provision (WEP) and Government Pension Offset (GPO) are two separate rules that can lower your Social Security benefit if you also receive a pension from work that was not covered by Social Security. The WEP affects your own retirement or disability benefit. The GPO affects spousal and survivor benefits you may receive based on someone else's Social Security record.

Both rules exist because Congress wanted to prevent people from receiving a full Social Security benefit plus a full government pension when they had not paid Social Security taxes on the job that earned the pension. If you worked for a federal, state, or local government agency that did not withhold Social Security taxes — common for teachers, police officers, firefighters, and some civil service workers — you may hit one or both of these limits.

The reduction is not optional and does not depend on your income level. If you meet the conditions, the rule applies automatically when you claim benefits. You cannot avoid it by claiming early or late, and you cannot negotiate around it.

Key Takeaways

  • The WEP reduces your own Social Security retirement or disability benefit by up to 50 percent of your government pension, with a current maximum reduction of around $1,000 per month (the exact amount changes yearly).
  • The GPO reduces spousal or survivor benefits you receive based on someone else's record by two-thirds of your government pension, which often wipes out the entire spousal or survivor benefit.
  • You are subject to WEP or GPO only if you receive a pension from government work that did not withhold Social Security taxes.
  • The reduction applies to your benefit amount before any cost-of-living adjustments, so your benefit shrinks each year as your pension grows.
  • Some government pensions are covered by Social Security, and workers in those jobs are not affected by WEP or GPO.

How the Windfall Elimination Provision works

The WEP changes the formula Social Security uses to calculate your retirement or disability benefit. Normally, Social Security replaces a higher percentage of your lower earnings and a lower percentage of your higher earnings — this is called the bend point formula. The WEP flattens that formula, so you get a smaller percentage across the board.

The reduction is capped at 50 percent of your government pension amount. So if your government pension is $2,000 per month, the WEP can reduce your Social Security benefit by up to $1,000 per month. However, there is also a dollar cap on the reduction itself. That cap changes each year with inflation; in recent years it has been around $1,000 to $1,100 per month, but you should check the current year's amount on the Social Security website.

The WEP applies only to benefits you earned yourself — your own retirement benefit or your own disability benefit. It does not affect benefits paid to your spouse or children based on your record. It also does not explore if you were born before January 2, 1924, or if you have 30 or more years of substantial earnings under Social Security (the earnings threshold changes yearly).

How the Government Pension Offset works

The GPO is stricter than the WEP. It reduces spousal benefits, widow or widower benefits, and ex-spouse benefits by two-thirds of your government pension. If your government pension is $1,500 per month, the GPO reduces your spousal or survivor benefit by $1,000 per month.

Because spousal benefits are typically 32 to 50 percent of the worker's benefit, and survivor benefits vary, the GPO often eliminates the entire spousal or survivor benefit. For example, if you are may have access to to a $600 spousal benefit and your government pension is $1,200 per month, the GPO reduces your benefit by $800 (two-thirds of $1,200), leaving you with nothing.

The GPO applies to benefits you receive as a spouse, ex-spouse, widow, or widower — not to your own retirement benefit. If you are also may have access to to your own Social Security benefit, the WEP may reduce that separately. You can receive your own benefit and have the GPO reduce your spousal or survivor benefit at the same time.

Which government pensions trigger WEP or GPO

Not all government pensions trigger these rules. You are subject to WEP or GPO only if your government pension came from work where you did not pay Social Security taxes. This is called non-covered government employment.

Common non-covered jobs include teachers in many states, police officers and firefighters in some states, federal employees hired before 1984, and some state and local civil service workers. However, many government employees do pay Social Security taxes — for example, federal employees hired after 1983 pay into Social Security, and some states have brought their teachers and public employees into the Social Security system.

The only way to know whether your government pension is covered or non-covered is to check with the agency that paid it or to contact Social Security directly. Social Security can look up your work history and tell you whether WEP or GPO will explore to your benefits.

What happens when you claim benefits

Social Security does not ask you whether you have a government pension when you file for benefits. However, when you report your pension to Social Security — or when Social Security learns about it through other records — the agency recalculates your benefit and applies WEP or GPO automatically.

If you have already been receiving benefits and then start receiving a government pension, Social Security will adjust your benefit downward. If you claim Social Security first and then start receiving a government pension later, the reduction takes effect the month after you report the pension or the month Social Security becomes aware of it.

You will see the reduction on your benefit statement. Social Security will send you a notice explaining the reduction and which rule applies. If you disagree with the calculation, you can request that Social Security review it, though the rules themselves cannot be appealed — they are federal law.

Strategies if WEP or GPO affects you

If you have not yet claimed Social Security, delaying your claim does not reduce the WEP or GPO amount. The reduction is based on your pension, not on when you claim. However, delaying does increase your own Social Security benefit rate, which means the WEP reduction (capped at 50 percent of your pension) takes a smaller bite out of a larger benefit.

If you are affected by the GPO and have a choice between claiming a spousal benefit or your own retirement benefit, compare the two. Sometimes your own benefit, even after WEP, is larger than a spousal benefit after GPO. Social Security can show you both amounts before you decide.

Some people in non-covered government employment have the option to switch into a covered system or to buy back Social Security coverage for their government work. Rules vary widely by employer and state. If you are still working in government, ask your pension administrator whether coverage options exist for you.

Frequently Asked Questions

Can I avoid WEP or GPO by not reporting my government pension?

No. Social Security obtains pension information from other government agencies and from your tax returns. Failing to report it does not prevent the reduction — it only delays when Social Security discovers it and applies the rule. Once discovered, the reduction is applied retroactively, and you may owe back payments.

Does WEP or GPO explore if my government pension is very small?

Yes. There is no minimum pension threshold. Even a small government pension triggers the rule. However, the reduction itself is capped — the WEP cannot reduce your benefit by more than 50 percent of your pension (up to the yearly dollar cap), and the GPO cannot reduce your benefit by more than two-thirds of your pension.

What if I worked for both a covered and non-covered government employer?

Social Security looks at your entire work history. If you have substantial earnings (30 or more years) under Social Security from covered employment, you may be exempt from WEP. For GPO, the rule applies if you receive any pension from non-covered government work, regardless of whether you also have covered employment.

Can my spouse or children be affected by my WEP or GPO?

The WEP affects only your own benefit, not family members' benefits based on your record. The GPO affects only benefits you receive as a spouse or survivor, not benefits paid to your own family members based on your record. Your spouse or children may receive their full family benefits even if your benefit is reduced.

Does the reduction change if my pension increases?

Yes. Both WEP and GPO are recalculated each year based on your current pension amount. If your pension increases, the reduction increases (up to the caps). If your pension decreases, the reduction decreases. This is one reason the reduction can grow larger than your Social Security benefit over time.
