Government Pension Offset (GPO): Complete Guide

Updated April 2026 | 10 min read

What Is the Government Pension Offset?

The Government Pension Offset (GPO) is a federal law that reduces your Social Security spousal or survivor benefits if you receive a government pension from work where you did NOT pay Social Security taxes.

Key Impact: GPO can completely eliminate your spousal or survivor benefit. The reduction is often much more severe than WEP because it applies to benefits based on someone else's work record.

Who Does GPO Affect?

CSRS employees (hired before 1984, no Social Security coverage)
Certain state and local government workers with non-Social Security pensions
Some teachers, police officers, firefighters with separate pension systems

The GPO Formula: 2/3 Offset Rule

GPO reduces your spousal or survivor benefit by two-thirds (2/3) of your government pension amount.

Your SS Benefit = Normal Spousal/Survivor Benefit - (2/3 × Government Pension)

Example Calculations

Example 1: Partial Reduction

Your CSRS pension: $2,400/month
2/3 of pension: $1,600
Normal spousal benefit: $1,000/month
GPO reduction: -$1,000 (capped at benefit amount)
Your actual spousal benefit: $0 (completely offset)

Example 2: No Impact

Your FERS pension: $1,800/month (you paid SS taxes)
GPO does NOT apply to FERS employees!
Your full spousal benefit: $1,000/month (no reduction)

GPO vs WEP: What's the Difference?

Feature	WEP	GPO
Affects	Your OWN retirement/disability benefit	SPOUSAL/SURVIVOR benefits
Reduction Formula	Modifies first bend point (max $557/mo in 2026)	2/3 of government pension
Can Be Eliminated	Yes, with 30+ years of substantial earnings	No years-based phaseout
Typical Impact	Moderate ($200-500/month reduction)	Severe (often eliminates entire benefit)

GPO Exceptions: When It Doesn't Apply

GPO does NOT apply in these situations:

FERS Employees: If you paid Social Security taxes during your federal service, GPO doesn't apply
Last 60 Months Under Social Security: You paid Social Security taxes for at least the last 60 months of covered employment (rules vary)
Age 62 Before July 1983: You turned 62 before July 1983 and were eligible for spousal benefits
Survivor Benefits Before July 1983: You became entitled to survivor benefits before July 1983
Government Employee Pension Based on Both Covered and Non-Covered Work: Complex calculations may apply

Strategies to Minimize GPO Impact

1. Switch to FERS (If Still Employed)

If you're currently under CSRS and still working, consider switching to FERS during open season. After 5 years under FERS, you'll be exempt from GPO.

2. Work in Social Security-Covered Employment

If possible, work at least 60 months (5 years) in a job that pays into Social Security immediately before retiring. This may exempt you from GPO under certain conditions.

3. Claim Your Own Retirement Benefit Instead

If your own Social Security retirement benefit (even with WEP reduction) is higher than the reduced spousal benefit, claim your own benefit instead.

4. Consider Divorced Spouse Benefits

If divorced, you may qualify for divorced spouse benefits on your ex-spouse's record. GPO still applies, but this may provide an alternative claiming strategy.
