What Social Security Benefit Offset (BSO) means for your payments

Benefit Offset is a reduction in your Social Security payment when you receive money from another source at the same time. The most common version is the Government Pension Offset (GPO), which cuts your spousal or survivor benefit if you also get a pension from work you did for a federal, state, or local government where you did not pay Social Security taxes.

The offset does not reduce your own retirement benefit — only benefits you receive based on someone else's work record. If you worked for a government employer and did not pay into Social Security during that job, the GPO can reduce a spousal benefit by up to two-thirds of your government pension amount.

A second, less common offset is the Windfall Elimination Provision (WEP), which reduces your own retirement or disability benefit if you also receive a government pension from work where you did not pay Social Security taxes. This affects your personal benefit, not a spousal one.

Key Takeaways

  • Government Pension Offset (GPO) reduces spousal or survivor benefits by two-thirds of your government pension if you worked for a government employer that did not withhold Social Security taxes.
  • Windfall Elimination Provision (WEP) reduces your own retirement or disability benefit if you have a government pension from non-Social Security-covered work.
  • The offset applies only if your government work was in a position where you did not pay Social Security taxes — most private sector and federal jobs are covered.
  • You can request a detailed benefit calculation from Social Security to see exactly how the offset affects your specific payments.
  • Some states and local governments have changed their pension systems to include Social Security coverage, which can eliminate the offset for future work.

Who the Government Pension Offset affects

The GPO applies to you if you receive a pension from government work and you are also may have access to to a spousal or survivor benefit on someone else's Social Security record. This most often happens when a spouse worked for a government agency (such as a state education department, city police force, or county clerk's office) and did not pay Social Security taxes during that employment.

The offset does not apply to your own retirement benefit based on your own work record. It only reduces benefits you receive because you are married to, divorced from, or a survivor of someone who paid into Social Security.

If you worked for the federal government, check whether your position was covered by the Federal Employees Retirement System (FERS) or the Civil Service Retirement System (CSRS). FERS employees pay Social Security taxes and are not subject to GPO. CSRS employees typically do not pay Social Security taxes and may face the offset if they claim a spousal or survivor benefit.

How the offset amount is calculated

Social Security reduces your spousal or survivor benefit by two-thirds of your government pension. For example, if your government pension is $900 per month, the offset is $600 (two-thirds of $900), and your spousal benefit is reduced by that amount.

If the offset is larger than your spousal benefit, Social Security will reduce your spousal benefit to zero. You will receive only your government pension. The offset does not take money from your pension itself — it only reduces the Social Security payment.

Social Security sends you a detailed benefit calculation statement that shows your full spousal benefit amount, the offset amount, and your net payment. Request this from your local Social Security office or through your online account at ssa.gov if you want to see the exact numbers before you claim.

The Windfall Elimination Provision and your own benefit

The WEP is different from GPO because it affects your own retirement or disability benefit, not a spousal one. It applies if you receive a government pension from work where you did not pay Social Security taxes, and you also have a Social Security benefit based on your own work record.

The WEP uses a different formula than GPO and typically reduces your benefit by 25 to 50 percent, depending on how many years you worked in jobs covered by Social Security. The reduction is capped at half of your government pension amount.

For example, if your government pension is $1,200 and your Social Security retirement benefit would be $800, the WEP might reduce your Social Security to $600. You receive both payments, but the Social Security portion is smaller.

Which government jobs trigger the offset

The offset applies only to government work where you did not pay Social Security taxes. Most federal employees hired after 1983 pay Social Security taxes and are not subject to GPO or WEP. State and local government employees vary widely — some participate in Social Security, and some do not.

Common positions that do not pay Social Security taxes include teachers in some states, police officers and firefighters in certain jurisdictions, and employees of some municipal utilities or special districts. However, this varies by state and by employer. Your government employer's payroll office can tell you whether your position was covered by Social Security.

If you are unsure, ask your former employer or pension administrator whether your position was covered by Social Security. You can also contact Social Security directly with your employer name and job title, and they can confirm coverage status.

What to do if you think the offset applies to you

Contact Social Security before you claim any benefit. Call 1-800-772-1213 or visit your local Social Security office with your government pension statement and any paperwork showing your employment dates and pension amount. Social Security will calculate your benefit with and without the offset so you can see the difference.

If you have not yet claimed, you have time to plan. Some people delay claiming a spousal benefit to allow their own retirement benefit to grow, which can be a better financial choice than claiming early and facing the offset. Others find that claiming only their government pension and skipping the spousal benefit makes more sense.

If you already receive benefits and think the offset was calculated incorrectly, you can request a recalculation. Bring documentation of your government pension amount and your employment dates. Social Security will review the calculation and issue a new payment if an error is found.

Frequently Asked Questions

Can I avoid the offset by waiting to claim?

Waiting to claim your own retirement benefit does not avoid GPO or WEP — the offset applies whenever you claim a spousal or survivor benefit, regardless of your age. However, delaying your own benefit increases its amount, which can offset the reduction from GPO in some cases. Social Security can show you the numbers for different claiming ages.

Does the offset apply to my spouse's benefit?

No. The offset applies only to you if you are the one receiving the government pension. Your spouse's Social Security benefit is not reduced because you have a pension. However, if your spouse also worked for a government employer without Social Security coverage, they would face their own offset.

What if I worked for a government employer but also paid Social Security taxes?

If your government position was covered by Social Security (meaning taxes were withheld from your paycheck), you are not subject to GPO or WEP. Confirm with your employer's payroll or pension office whether your specific position was covered. Many federal employees and some state and local employees are covered and will not face an offset.

Can the offset change after I start receiving benefits?

The offset amount can change if your government pension amount changes. If your pension increases, the offset increases. If your pension decreases, the offset decreases. Social Security recalculates your payment automatically when your pension changes, so notify Social Security if your pension amount is adjusted.

What documents do I need to bring to Social Security?

Bring your government pension statement showing the monthly amount, your employment dates with the government employer, and any paperwork showing the employer name and your job title. If you have a divorce decree and are claiming on an ex-spouse's record, bring that as well. Social Security will tell you if they need additional documents.
