Social Security: The Government Pension Offset (GPO)

Summary
Social Security spousal benefits were established in the 1930s to help support wives who are
financially dependent on their husbands. It has since become more common for both spouses in a
couple to work, leading to more cases in which both members of a couple are entitled to Social
Security or other government pensions based on their own work records. Social Security does not
provide both a full retired-worker and a full spousal benefit to the same individual.
Two provisions are designed to reduce the Social Security spousal benefits of individuals who are
not financially dependent on their spouses because they receive benefits based on their own work
records. These are
• the dual entitlement rule, which applies to spouses who qualify for both
(1) Social Security spousal benefits based on their spouses’ work histories in
Social Security–covered employment and (2) their own Social Security retired-
or disabled-worker benefits, based on their own work histories in Social
Security–covered employment; and
• the Government Pension Offset (GPO), which applies to spouses who qualify for
both (1) Social Security spousal benefits based on their spouses’ work histories in
Social Security–covered employment and (2) their own retirement or disability
government pensions, based on their own work in government employment that
was not covered by Social Security.
The dual entitlement rule requires that 100% of a Social Security retirement or disability benefit
as a covered worker is subtracted from any Social Security spousal or widow(er)’s benefit an
individual is eligible to receive. The GPO reduces Social Security spousal or widow(er)’s benefits
by two-thirds of the retirement or disability pension from noncovered government employment.
The GPO does not reduce the benefits of the spouse who was covered by Social Security. In
December 2023, 745,679 Social Security beneficiaries (about 1% of all beneficiaries) had spousal
or widow(er)’s benefits reduced by the GPO.
Opponents contend that the GPO is imprecise and can be unfair. Defenders argue it is the best
method currently available for preserving the spousal benefit’s original intent of supporting
financially dependent spouses and for eliminating an unfair advantage for spouses working in
non–Social Security–covered employment compared with spouses working in Social Security–
covered jobs (who are subject to the dual entitlement rule).

Social Security: The Government Pension Offset (GPO)

Background
In general, Social Security spousal and survivor benefits are paid to the spouses of retired,
disabled, or deceased workers covered by Social Security. The basic spousal benefit equals 50%
of a retired or disabled worker’s benefit and the basic survivor benefit equals 100% of a deceased
worker’s benefit.
Spousal and widow(er)’s benefits, which Congress created in 1939 and 1950,1 are intended for
individuals who are financially dependent on a working spouse. For this reason, but also because
of the costs, Social Security does not provide both full worker and full spousal (or survivor)
benefits to the same individual. For persons who qualify for both a Social Security worker benefit
(retirement or disability) based on their own work history and a Social Security spousal (or
survivor) benefit based on a spouse’s work history, the dual entitlement rule effectively caps total
benefits at the higher of the worker’s own benefit or the spousal (or survivor) benefit. The dual
entitlement rule has been in law since 1939, when Congress created benefits for eligible wives
and widows. The Government Pension Offset (GPO) is analogous in purpose to the dual
entitlement provision and applies to individuals who qualify for both a retirement or disability
pension based on their own non–Social Security–covered government work and a Social Security
spousal or survivor benefit based on a spouse’s work in Social Security–covered employment.2
The GPO was originally established in 1977. It replaced an earlier dependency test for spousal
and survivor benefits that had been in law since 1950. The dual entitlement rule and the GPO
share the same intent—to reduce the Social Security spousal and survivor benefits of individuals
who are not financially dependent on their spouses because they receive their own retired-worker
or disabled-worker Social Security benefits, or their own non–Social Security pension benefits.
Social Security Covered and Noncovered Work
A worker is covered by Social Security if he or she works in covered employment and pays into
Social Security through the Federal Insurance Contributions Act (FICA) taxes or Self-
Employment Contributions Act taxes, or both, on wages and/or self-employment income. To be
eligible for a Social Security retired-worker benefit, a worker generally needs 40 earnings credits
(10 years of Social Security–covered employment).3 Disabled workers are generally required to
have worked fewer years, depending on the age at which the worker became disabled.4
Approximately 94% of workers are covered by Social Security in 2024.5 The majority of
noncovered positions are held by government employees: most federal employees hired before

1 Wife’s and widow’s benefits were created in 1939, while husband’s and widower’s benefits were enacted in 1950. As
a result of the Supreme Court’s decision in Obergefell v. Hodges, the Social Security Administration is now able to
recognize same-sex marriages and certain nonmarital legal relationships in all states, territories, and the District of
Columbia. See CRS Report R41479, Social Security: Revisiting Benefits for Spouses and Survivors.
2 The Government Pension Offset (GPO) is often confused with the Windfall Elimination Provision (WEP), which
reduces Social Security benefits that a person receives as a worker if he or she also has a government pension based on
work that was not covered by Social Security. For additional information on the Windfall Elimination Provision (WEP),
please refer to CRS Report 98-35, Social Security: The Windfall Elimination Provision (WEP).
3 A worker may earn up to four earnings credits per calendar year. In 2024, a worker earns one credit for each $1,730 of
covered earnings, up to a maximum of four credits for covered earnings of $6,920 or more. Earnings credits are also
called quarters of coverage.

1984 and some state and local government employees.6 Nationwide, approximately 72% of state
and local government employees were covered by Social Security in 2019.7 However, coverage
varied from state to state. For example, approximately 95% of state and local employees in New
York were covered by Social Security, whereas less than 3% of state and local employees in Ohio,
and about 3% in Massachusetts, were covered.8
The Dual Entitlement Rule and the GPO
The GPO is intended to approximate Social Security’s dual entitlement rule. Both provisions are
intended to reduce the Social Security benefits of spouses or widow(er)s who are not financially
dependent on their spouses because they receive retirement or disability benefits based on their
own work records.
Dual Entitlement Rule
Without the dual entitlement rule, a couple with two earners covered by Social Security would
receive two full primary benefits as well as two full spousal or widow(er)’s benefits. The Social
Security dual entitlement rule requires that a beneficiary effectively receive the higher of the
Social Security worker’s benefit or the spousal or widow(er)’s benefit, but not both. The total
benefit received by a worker consists of his or her own worker benefit plus the excess of the
spousal or widow(er)’s benefit (if any) over his or her own benefit—not the sum of the two
benefits. So, in cases where the spousal or widow(er)’s benefit is higher than the worker’s own
benefit, the worker receives his or her own worker benefit plus the reduced spousal or
widow(er)’s benefit, which is the difference between the spousal or widow(er)’s benefit and the
worker’s own benefit (100% reduction). In cases where the worker’s own benefit is higher than
the spousal or widow(er)’s benefit, the worker receives only his or her own benefit (i.e., the
spousal or widow[er]’s benefit is reduced to zero).
Table 1 demonstrates how the Social Security dual entitlement rule is applied to spouses.

Coverage of Workers from their State and Local Government Employment in 2019.”
8 See CRS Report R46961, Social Security Coverage of State and Local Government Employees. The disparity in
coverage among states occurs because, while Social Security originally did not cover any state and local government
workers, over time the law has changed. Most state and local government employees became covered by Social
Security through voluntary agreements between the SSA and individual states, known as Section 218 Agreements
because they are authorized by §218 of the Social Security Act. Beginning in July 1991, state and local employees who
were not members of a public retirement system or covered by a Section 218 agreement were mandatorily covered by
Social Security.

Social Security: The Government Pension Offset (GPO)

In this example, both John and Mary have worked enough years in Social Security–covered
positions (i.e., paid into Social Security) to qualify for Social Security retirement benefits. John
has earned a monthly Social Security worker benefit of $2,000. His wife Mary has earned a
monthly Social Security worker benefit of $900. Both John and Mary are also eligible for spousal
benefits based on the other’s earnings: John is eligible for a $450 monthly spousal benefit, and
Mary is eligible for a $1,000 monthly spousal benefit. Under the dual entitlement rule, John will
not be paid a spousal benefit because his $2,000 worker benefit based on his own earnings is
higher than and more than offsets the potential $450 spousal benefit. Mary’s worker benefit of
$900 must be subtracted from her potential $1,000 spousal benefit, and only the difference of
$100 is paid as a spousal benefit. In total, Mary will receive $1,000 monthly—$900 as a Social
Security worker benefit and $100 as a Social Security spousal benefit. The Social Security
benefits received by the couple would total $3,000 per month.
If John were to predecease Mary, Mary would then be entitled to a monthly widow’s benefit of up
to 100% of John’s monthly amount.9 Mary would continue to collect her own benefit of $900
monthly, and that amount would offset the potential $2,000 monthly widow’s benefit based on
John’s work history. Thus, Mary would receive a Social Security worker benefit of $900 and a
Social Security widow’s benefit of $1,100 (or $2,000-$900), for a total monthly benefit of $2,000.
Because most workers are in Social Security–covered employment, the dual entitlement scenario
is more common than the GPO among two-earner couples. In 2022, approximately 7.5 million
out of 48.6 million Social Security retired-worker beneficiaries, or about 15%, were dually
entitled.10
Government Pension Offset Formula
The Social Security spousal or widow(er)’s benefit of a person who also receives a pension from
government employment (federal, state, or local) that was based on work not covered by Social
Security is reduced by a provision known as the Government Pension Offset (GPO).11 The GPO
reduction to Social Security spousal and widow(er)’s benefits equals two-thirds of the pension
from noncovered government employment. If the pension from noncovered work is sufficiently
large in comparison to a person’s Social Security spousal or widow(er)’s benefit, the GPO may
eliminate the entire Social Security spousal or widow(er)’s benefit.
In December 2023, 745,679 Social Security beneficiaries (about 1% of all beneficiaries) had
spousal or widow(er)’s benefits reduced fully or partially by the GPO (this figure does not include
persons who were eligible for spousal or widow(er)’s benefits but were deterred from filing for
them because of the GPO).12 The GPO does not affect the amount of the Social Security benefit a

9 Technically, a widow(er)’s benefit is equal to up to 100% of the worker’s Primary Insurance Amount (PIA). The
worker’s PIA is the benefit payable to the worker at full retirement age before any applicable reductions. The
terminology used here is intended for ease of reference. For more information, see CRS Report R42035, Social Security
Primer.
10 SSA, Annual Statistical Supplement 2023, Table 5.G1 and Table 5.A1. The term dually entitled applies only to those
who receive spousal or widow(er)’s benefits. If an individual’s own worker benefit is greater than his or her spousal or
widow(er)’s benefit, that person receives the higher worker benefit and is not considered dually entitled. Administrative
data do not provide the number of people in this latter category.
11 A pension in this setting is referred to as a periodic or lump-sum payment received from an employer’s retirement or
disability plan based upon the individual’s noncovered earnings while in the service of a federal, state, or local
government. The payment can be from either a defined benefit or defined contribution plan—for example, 401(k),
403(b), or 457. For more information, see SSA, Program Operations Manual System (POMS), “GN 02608.100

worker may receive based on his or her own work in Social Security–covered employment, but it
does limit the amount that can be paid to his or her spouse or widow(er) who has worked in non–
Social Security–covered employment.
Table 2 provides an example of how the GPO is applied, assuming that John worked in Social
Security–covered employment while Mary spent her full career in state or local government
employment that was not covered by Social Security.

Note: Dashes means not applicable.
In this example, John worked enough years in Social Security–covered employment to qualify for
a monthly Social Security retired-worker benefit of $2,000. His wife, Mary, is not eligible for a
Social Security retired-worker benefit because she worked in a non–Social Security–covered
government position and did not contribute to Social Security. Instead, Mary is eligible for a $900
government pension based on her work in a non–Social Security–covered position. Mary is also
eligible for a Social Security spousal benefit of up to $1,000 based on John’s work history. Under
the GPO, Mary’s potential Social Security spousal benefit is reduced by an amount equal to two-
thirds of her non–Social Security–covered government pension (or a reduction of $600), and the
difference of $400 ($1,000-$600) is paid to her as a Social Security spousal benefit. In total, Mary
will receive retirement benefits of $1,300 per month: $900 from her noncovered pension and
$400 from her Social Security spousal benefit.13
If John predeceased Mary, then two-thirds of her $900 noncovered pension ($600) would be used
to partially offset the $2,000 Social Security benefit she would be eligible for as a widow based
on John’s work history. She would receive a $1,400 monthly widow’s benefit from Social
Security (in addition to her $900 monthly noncovered pension benefit).
Table 3 highlights the differences between the dual entitlement rule and the GPO.

13 In this example, John is not eligible for a Social Security spousal benefit because Mary’s employment was not
covered by Social Security.

Rationale and Legislative History
Spouses’ Financial Dependence
The policy rationale for Social Security spousal benefits has been, since the creation of spousal
benefits in the 1930s, to support spouses who are financially dependent on the working spouse.
The dual entitlement rule has operated since 1939 as a gauge of financial dependence.
Parity Between Spouses Subject to the Dual Entitlement Rule and
the GPO
The GPO is intended to place spouses and widow(er)s whose government employment was not
covered by Social Security in approximately the same position as spouses whose jobs were
covered by Social Security. Before the GPO was enacted in 1977, workers who received pensions
from a government job not covered by Social Security could also receive full Social Security
spousal or widow(er)’s benefits even though they were not financially dependent on their spouses.
The scenarios below demonstrate why the law was changed.
Table 4 shows how the spousal benefit of the same individual, Mary, would vary under three
scenarios: (1) as a dually entitled recipient of Social Security retirement and spousal benefits;
(2) as the recipient of a noncovered government pension and Social Security spousal benefits
before the GPO was enacted; and (3) as the recipient of a noncovered government pension and
Social Security spousal benefits after the GPO was enacted. In all three examples, it is assumed
that Mary is potentially eligible for a Social Security spousal benefit of $1,000 per month,
computed as 50% of her husband’s monthly Social Security benefit of $2,000.
As a dually entitled retiree, under the first scenario, Mary’s $1,000 Social Security spousal benefit
is reduced by her own Social Security retired-worker benefit of $900, leaving her with a net
spousal benefit of $100 and a total (combined) Social Security benefit of $1,000. Under the
Congressional Research Service

Social Security: The Government Pension Offset (GPO)

second scenario (where Mary receives a noncovered government pension instead of a Social
Security retirement benefit), before the GPO takes effect, Mary’s Social Security spousal benefits
are not reduced at all and she receives a full Social Security spousal benefit of $1,000, plus the
noncovered pension of $900, for total monthly pension benefits of $1,900. Under the third
scenario (after the GPO was enacted in 1977), Mary’s Social Security spousal benefit is reduced
by two-thirds of her $900 noncovered government pension, leaving her with a net Social Security
spousal benefit of $400 ($1,000-$900*2/3) and a total monthly pension benefit of $1,300 ($900
from the noncovered pension + $400 from the Social Security spousal benefit).
Note that the reduction to Social Security spousal benefits is smaller under the GPO than it is
under the dual entitlement rule: Mary receives monthly Social Security spousal benefits of $100
under the dual entitlement rule, compared with $400 under the GPO. Her total monthly retirement
benefits are $1,000 under the dual entitlement rule, compared with $1,300 under the GPO. For
those under the dual entitlement rule, the Social Security spousal benefit is reduced by one dollar
for every dollar of Social Security retirement benefits based on their own work histories in Social
Security–covered employment. For those under the GPO, however, the Social Security spousal
benefit is reduced by approximately 67 cents for every dollar of a pension from noncovered
government employment.

Why a Two-Thirds Reduction?
The GPO was originally established in 1977 (P.L. 95-216) and replaced an earlier dependency test
for spousal benefits that had been in law since 1950.14 The 1977 law provided that 100% of the
noncovered government pension be subtracted from the Social Security spousal or widow(er)’s
benefit. If the original legislation had been left intact, individuals affected by the dual entitlement
rule and the GPO would have been treated identically because, in both cases, the Social Security
spousal or widow(er)’s benefit would have been reduced by 100% of the pension from
noncovered employment.
The GPO’s two-thirds offset rule was established by the Social Security Amendments of 1983
(P.L. 98-21), which made a number of amendments to Social Security. One section of the House
version of this law proposed that the amount used in calculating the offset be one-third of the
noncovered government pension. The Senate version contained no such provision and would
therefore have left standing the 100% offset that existed at the time. The conferees adopted the
House bill except that the offset was fixed at two-thirds of the noncovered government pension.15
Who Is Affected by the GPO?
In 2019, approximately 6.5 million state and local government workers (28% of all state and local
government workers) were in non–Social Security–covered positions.16 A government worker
who does not pay into Social Security may potentially be affected by the GPO if he or she is
entitled to a Social Security spousal or widow(er)’s benefit based on a spouse’s or ex-spouse’s
work in Social Security–covered employment.
Generally, federal government employees hired before 1984 are covered by the Civil Service
Retirement System (CSRS) and are not covered by Social Security; therefore, they may be
subject to the GPO.17 Most federal workers first hired into federal service after 1983 are covered
by the Federal Employees’ Retirement System (FERS), which includes Social Security coverage.
Thus, although FERS retirees are not subject to the GPO, they, like all covered workers, may be
subject to the Social Security dual entitlement rule.
As of December 2023, 745,679 Social Security beneficiaries, or about 1% of all beneficiaries, had
spousal or widow(er)’s benefits reduced by the GPO (not counting those who were potentially
eligible for spousal or widow(er)’s benefits but were deterred from filing for them because of
their expectation that the GPO would eliminate the spousal or widow(er)’s benefit). Of these
persons subject to the GPO, 51% were spouses and 49% were widows and widowers. About 83%
of all affected persons were women.18 Table 5 provides a breakdown of the affected beneficiaries
by state and type of benefit.

14 The dual entitlement rule has been in law since 1939, when spousal benefits were introduced.
15 Effectively, the GPO offset formula assumes that two-thirds of the government pension is roughly equivalent to the
Social Security retirement (or disability) benefit the spouse would have earned as a worker if his or her job had been
covered by Social Security.

Government Employment in 2019.”

System (FERS) must work for five years under FERS to be exempt from the GPO.

Notes: Includes persons entitled to spousal/widow(er)’s benefits only and those dually entitled to
spousal/widow(er)’s and worker benefits.
a. Individual received no Social Security spousal or widow(er)’s benefit because the reduction in the Social
Security spousal or widow(er)’s benefit (a reduction equal to two-thirds of the pension from noncovered
government employment) was greater than the Social Security benefit itself. Either the noncovered pension
was large, or the potential Social Security benefit was small (or both).
b. Individual received partial Social Security spousal or widow(er)’s benefits because the reduction in the Social
Security benefit (a reduction equal to two-thirds of the pension from noncovered government employment)
was less than the Social Security benefit itself.
In December 2023, the average noncovered government pension amount for persons affected by
the GPO was $2,759 per month ($2,522 per month for women and $3,882 per month for men).19
The average pre-offset Social Security spousal benefit at that time was $1,110 per month ($1,190

per month for women and $729 per month for men).20 The average reduction caused by the GPO
was $843 per month ($873 per month for women and $699 per month for men).21 The average
Social Security spousal benefit component after applying the GPO was $267 per month ($317 per
month for women and $30 per month for men).22 Among beneficiaries who were affected by the
GPO in December 2023, 68% had their potential Social Security spousal or widow(er)’s benefit
fully offset by the GPO reduction; that is, their potential Social Security spousal or widow(er)’s
benefit was reduced to zero.23 Among those whose Social Security spousal or widow(er)’s benefit
was partially offset by the GPO reduction, on average, the reduced Social Security benefit
comprised about 43% of the total payment received (noncovered government pension plus
reduced Social Security benefit).24
In comparison to the 734,601 beneficiaries affected by the GPO in December 2022,25 the dual
entitlement rule affected approximately 7.5 million retired-worker beneficiaries. About 7.2
million (96%) of all affected beneficiaries were women.26 Wives made up 41% of all dually
entitled retired workers, and widows made up 55%. Among dually entitled workers, the average
Social Security total benefit (retired worker plus spouse or widow(er)’s benefit) received was
$1,644.27 Of this amount, $939 was the retired-worker component of the benefit. The spousal or
widow(er)’s benefit component was $706 (after reduction for dual entitlement).28 On average,
among dually entitled retired workers, therefore, the spousal or widow(er)’s benefit comprised
about 43% of the total Social Security benefit received.
Issues
Opponents argue that the GPO is not well understood and that it harms lower-wage workers. The
GPO’s defenders maintain that it helps ensure that only financially dependent spouses receive the
Social Security spousal or widow(er)’s benefit, while curtailing what otherwise would be an
unfair advantage for government workers who are not covered by Social Security.

Awareness of the GPO and Retirement Preparedness
The GPO’s critics say that it is not well understood and that many affected by it are unprepared
for a smaller Social Security benefit than they had assumed in making retirement plans. The
provision’s supporters say it has been law for more than 40 years (it was enacted in 1977);
therefore, people have had ample time to adjust their retirement plans. P.L. 108-203, passed in
2004, included a provision that sought to ensure that SSA and government employers notify
potentially affected individuals about the effect of the GPO and the Windfall Elimination
Provision (WEP).29
Section 1143 of the Social Security Act (as amended) requires SSA to provide Social Security
number holders with annual statements that contain certain information from their Social Security
records.30 The annual statement is now referred to as the Social Security Statement or, more
simply, as the Statement. In accordance with the law, the Statement advises the individual that
participation in a retirement plan or receipt of a pension based on earnings for which he or she did
not pay Social Security payroll taxes could result in lower Social Security benefits. The Statement
provides a link to related information about the WEP and the GPO on SSA’s website. Under
current policy, annual Statements are available online for any individual who creates a “my Social
Security Account” on SSA’s web portal. SSA sends an email each year to “my Social Security
Account” holders reminding them to check their annual Statements online. SSA automatically
mails paper Statements annually to any individual who (1) is aged 60 or older, (2) has not yet
claimed benefits, and (3) has not created a “my Social Security Account.” A Statement is mailed
three months before an individual’s birthday. Individuals can also request a mailed paper
Statement at any time.31
GPO Reduction Smaller Than Dual Entitlement Reduction
The reduction to Social Security spousal or widow(er)’s benefits is smaller under the GPO than it
is under the dual entitlement rule. Those under dual entitlement face a 100% offset to spousal or
widow(er)’s benefits for every dollar received from a Social Security retired-worker benefit,
whereas those under the GPO face an offset to spousal and widow(er)’s benefits equal to two-
thirds of a non–Social Security–covered pension. In the example shown in Table 4, in which
comparable spouses each receive a $900 retirement benefit based on their own work histories,
applying the dual entitlement provision’s 100% offset results in a $100 monthly Social Security
spousal benefit for Mary. Comparatively, Mary qualifies for a $400 monthly Social Security
spousal benefit under the GPO’s two-thirds offset.
Parity Among Social Security–Covered Workers and
Noncovered Workers
The majority of state and local government workers, and federal employees hired since 1984, are
covered by Social Security. Some argue that eliminating the GPO would be unfair to government
employees in Social Security–covered positions, who would continue to be subject to the dual
entitlement provision. As discussed above, for those under dual entitlement, the Social Security

29 The WEP reduces Social Security benefits that a person receives as a worker if he or she also has a government
pension based on work that was not covered by Social Security.

Social Security: The Government Pension Offset (GPO)

spousal or widow(er)’s benefit is reduced by one dollar for every dollar of Social Security
retirement benefits based on their own work history in Social Security–covered employment. For
those under the GPO, however, the Social Security spousal or widow(er)’s benefit is reduced by
approximately 67 cents for every dollar of a pension from noncovered government employment.
Impact on Low-Wage Workers
There is disagreement about the original intention of the GPO, which was enacted in 1977. Some
argue that the original purpose was to prevent higher-paid workers from reaping overly generous
spousal or widow(er)’s benefits. Others contest this, saying that the GPO was never targeted to a
particular income group.
The GPO’s opponents argue that the provision hurts lower- and middle-wage workers, such as
teachers, and in some circumstances throws these workers into poverty. Opponents also say that
the GPO is especially disadvantageous for surviving spouses.
Evidence of the GPO’s effect on low earners comes from SSA data on the program.32 While 68%
of those affected by the GPO in December 2023 had their benefits fully offset, about 14% of
those with noncovered pensions of less than $1,000 per month had their benefits fully offset,
compared with 52% of those with monthly noncovered pensions between $1,000 and $1,999,
83% of those between $2,000 and $2,999, and nearly 100% of individuals with noncovered
pensions over $3,000 per month.33 Among the group of individuals whose benefits were
completely eliminated by the GPO, about 4% of this group had a noncovered pension amount
lower than $1,000 per month.34 And among the beneficiaries who received some Social Security
spousal or widow(er)’s benefit after GPO reduction (partially offset), about 56% of them had a
noncovered government pension amount less than $1,000 per month, and almost 100% of them
had a noncovered government pension amount less than $3,000 per month.35 Thus, if the
noncovered pension amount is a reflection of the approximate earnings levels of individuals
affected by the GPO, a greater percentage of those with lower earnings receive at least a partial
Social Security benefit relative to the overall GPO-affected population.

32 How an individual would be affected by the GPO versus the dual entitlement rule is determined by several key
variables, including the relative earnings level of the individual, the timing of the worker’s noncovered employment
during his or her career, and the number of years in noncovered employment. The primary difference between
outcomes among high and low earners is driven by the fact that a worker’s Social Security benefit (the basis for the
dual entitlement offset, which reduces the spousal benefit by 100% of this amount) is progressive, while pensions from
noncovered government employment (the basis for the GPO reduction, which reduces spousal benefits by two-thirds of
this amount) generally provide a pension that is the same fixed percentage of earnings regardless of the earnings level.
As earnings rise, if the earnings are from noncovered employment then the pension from this employment rises
proportionately; if the earnings are from covered employment, then the Social Security benefit, which is progressive,
rises less than proportionately. Hence for high earners, the GPO offset to spousal benefits, which is two-thirds of
noncovered pensions and which rises proportionately as income rises, becomes more significant than the dual-
entitlement offset to spousal benefits, which involves a 100% offset to the Social Security benefit and which rises more
slowly as income rises. In general, any combination of variables (such as earnings level, timing of noncovered
employment, or number of years in noncovered employment) that increases the size of the noncovered government
pension more than it increases the size of the Social Security benefit (assuming the same earnings were covered by
Social Security) would make the dual entitlement rule more advantageous to an individual than the GPO.

Regarding concerns about pushing those affected by the GPO into poverty, in 2001, the poverty
rate among those affected by the GPO was approximately 6.0%, whereas the poverty rate for
those affected by the dual entitlement rule was approximately 8.9%.36 The poverty rate for all
Social Security beneficiaries aged 65 and older was about 8.5%. For comparison purposes, the
poverty rate for the general population at that time was approximately 11.3%.
Imprecision of the Two-Thirds Offset to Noncovered
Government Pensions
Opponents point out that whatever the rationale for the GPO, reducing everyone’s spousal or
widow(er)’s benefit by two-thirds of their government pension is an imprecise way to estimate
what the spousal benefit would have been if the government job had been covered by Social
Security. If two-thirds of the government pension were in fact a good proxy for Social Security
retirement benefits, there would be no significant difference in outcomes between the dual
entitlement rule and the GPO. As noted above (see the previous section, “Impact on Low-Wage
Workers”), however, there is great variation in outcomes. The GPO may lead to a smaller offset
relative to the dual entitlement rule for low earners than for high earners.
Ideally, opponents argue, the way to compute the offset is to replicate the dual entitlement rule.
Under the dual entitlement rule, the reduction to the spousal or widow(er)’s benefit is Social
Security worker’s benefit, that is, applying Social Security benefit formula to the spouse’s all
Social Security–covered earnings. To mimic that approach, in cases that the spouse’s entire career
was not covered by Social Security, the GPO reduction would be an amount equivalent to
applying the Social Security benefit formula to all those noncovered earnings.37 All covered and
noncovered earnings have been reported to SSA on Form W-2 since 1978.38 Although some initial
records were incomplete or duplicative, sufficient earnings records over a worker’s entire
working life are now available to SSA. This data’s availability means that the offset based on both
spouses’ covered and noncovered earnings is now an option for Congress to consider.39
Applying the GPO to Government Versus Private Pensions
Some question why the GPO does not apply to the spousal or widow(er)’s benefits received by
private-sector workers’ spouses, who may receive private, employer-sponsored pensions (defined

36 Poverty rates were calculated by David Weaver, SSA’s Office of Retirement Policy, using the March 2001 Current
Population Survey (CPS). Poverty status is taken directly from the CPS and is thus subject to errors in the reporting of
income. The sample for the GPO and dually entitled poverty rates only includes persons for whom SSA administrative
records could be matched. The sample size for the GPO poverty rate is relatively small (130 cases). Poverty rates for
the Social Security beneficiary population aged 65 and over and for the general population do not require matched data
and are based completely on CPS data. Updated data for this comparison are not available.
37 In cases that the spouse’s career is split between covered and noncovered jobs, the GPO reduction would be the
Social Security benefit based on total earnings subtracting the Social Security benefit based on covered earnings—that
is, the part of Social Security benefits based on total earnings that are attributable to noncovered earnings. In this
situation, the person might be entitled to both Social Security worker’s benefits and spousal or widow(er)’s benefits
(i.e., dully entitled), and the person might be affected by both the Windfall Elimination Provision (WEP) and the GPO.
The person’s Social Security worker’s benefit might be reduced by the WEP, and the person’s Social Security spousal
or widow(er)’s benefit might be reduced by both Social Security worker’s benefit (affected by the WEP) and the GPO
reduction. For more information, see CRS Report R45845, Social Security: Beneficiaries Affected by Both the Windfall
Elimination Provision (WEP) and the Government Pension Offset (GPO).

benefit or defined contribution) in addition to Social Security benefits. Generally, the private-
sector employment on which the private pension is based would be covered by Social Security.
Therefore, the dual entitlement rule (which the GPO is meant to replicate) would instead reduce
any Social Security spousal or widow(er)’s benefits for which a beneficiary might be eligible. As
noted earlier, in many cases the dual entitlement rule would produce a larger reduction in spousal
or widow(er)’s benefits than does the GPO.
Cost of Eliminating the GPO
Some argue that weakening or eliminating the GPO would be costly at a time when neither Social
Security nor the federal budget is in sound financial condition. In 2022, the Congressional Budget
Office (CBO) projected that eliminating the GPO would have cost $107 billion over the period
FY2022-FY2032.40 Such a move could also lead to demands for repeal of the dual entitlement
rule to ensure parallel treatment for those working in Social Security–covered employment. In
2003, SSA estimated that eliminating the dual entitlement rule would cost approximately $500
billion over a five-year period.41
Last Legislative Change: The GPO Last-Day Rule
A burgeoning controversy arose in the 108th Congress with the revelation that a growing number
of state and local government workers had been making use of a little-known provision of the law
that allowed them to escape the application of the GPO if they switched jobs at the very end of
their government careers. That provision granted an exception to the GPO if, on the last day of
one’s government service, he or she worked in a Social Security–covered position. On August 15,
2002, the Government Accountability Office (GAO) released a report that found that, as of June
2002, 4,819 individuals in Texas and Georgia had switched to Social Security–covered positions
to avoid having the GPO applied to their Social Security spousal benefits. The GAO projected
that the cost to the program for these cases could be about $450 million.42
On February 11, 2004, the House of Representatives agreed to Senate amendments and passed
H.R. 743, the Social Security Protection Act of 2003, which became P.L. 108-203.43 As discussed
below, P.L. 108-203 eliminated the last-day exception clause by requiring those workers
switching from noncovered positions to Social Security–covered positions to work in the covered

40 CBO also estimated that, accounting for the interaction among Social Security provisions and other federal programs,
eliminating the WEP and the GPO would have cost $183 billion over the period FY2022-FY2032. See CBO, Cost
Estimate: H.R. 82, Social Security Fairness Act of 2021, September 20, 2022, https://www.cbo.gov/publication/58488.
SSA’s Office of the Chief Actuary projected that repealing the WEP and the GPO would have increased program costs
by $146 billion over the period including 2022-2031. The estimates also show that the bill would have reduced the
long-range actuarial balance (i.e., increase the net long-term cost) of the combined Social Security trust funds by 0.12%
of taxable payroll. See letter from Stephen C. Goss, Chief Actuary, SSA, to the Hon. Rodney Davis and the Hon.
Abigail Spanberger, U.S. House of Representatives, July 20, 2022, https://www.ssa.gov/OACT/solvency/
DavisSpanberger_20220720.pdf. The projection was based on the intermediate assumptions of the 2022 Social Security
trustees report. Taxable payroll is the total amount of earnings in the economy that is subject to Social Security payroll
and self-employment taxes (with some adjustments).
