Social Security: The Windfall Elimination Provision (WEP)
Summary
Social Security is a work-based, federal insurance program that provides income support to
workers and their eligible family members in the event of the worker’s retirement, disability, or
death. A worker’s employment or self-employment is considered covered by Social Security if the
services performed in that job result in earnings that are taxable and creditable for program
purposes. Although participation in Social Security is compulsory for most workers, about 6% of
al workers in paid employment or self-employment are not covered by Social Security.
The windfall elimination provision (WEP) is a modified benefit formula that reduces the Social
Security benefits of certain retired or disabled workers who are also entitled to pension benefits
based on earnings from jobs that were not covered by Social Security and thus not subject to the
Social Security payroll tax. Its purpose is to remove an unintended advantage or “windfal ” that
these workers would otherwise receive as a result of the interaction between the regular Social
Security benefit formula and the workers’ relatively short careers in Social Security-covered
employment.
In December 2020, about 1.9 mil ion people (or about 3% of al Social Security beneficiaries)
were affected by the WEP. Those workers mainly include state and local government employees
covered by alternative staff-retirement systems as wel as most permanent civilian federal
employees hired before January 1, 1984, who are covered by the Civil Service Retirement System
(CSRS).
WEP’s supporters argue that the formula is a reasonable means to prevent overgenerous payments
and unintended benefits to people who have earnings not covered by Social Security and receive
pensions from noncovered work. Opponents argue that the provision substantial y reduces a
benefit that workers may have included in their retirement plans, and it reduces benefits
disproportionately for lower-earning households. Others criticize the current WEP formula as an
imprecise way to determine the actual windfal when applied to individual cases.
Recent legislation has general y proposed either to eliminate the provision for al or some affected
beneficiaries, or replace the current-law provision with a new proportional formula based on past
earnings from both covered and noncovered employment.

Social Security: The Windfall Elimination Provision (WEP)
Introduction
Social Security provides insured workers and their eligible family members with a measure of
protection against the loss of income due to the worker’s retirement, disability, or death. The
amount of the monthly benefit payable to workers and their family members is based on the
worker’s career-average earnings from jobs covered by Social Security (i.e., jobs in which the
worker’s earnings were subject to the Social Security payroll tax).1 The Social Security benefit
formula is weighted to replace a greater share of career-average earnings for low-paid workers
than for high-paid workers. This means that low-paid workers receive relatively high benefits in
relation to their payroll tax contributions, although the dollar amount of their benefits is lower
than that provided to high-paid workers.
The benefit formula, however, cannot distinguish between workers who have low career-average
earnings because they worked for many years at low earnings in Social Security-covered
employment and workers who appear to have low career-average earnings because they worked
for many years in jobs not covered by Social Security. (Those years show up as zeros in their
Social Security earnings records, which, when averaged, lower their career earnings from covered
work.) Consequently, workers who split their careers between covered and noncovered
employment—even highly paid ones—may also receive the advantage of the weighted formula.
The windfall elimination provision (WEP) is a modified benefit formula designed to remove the
unintended advantage, or “windfal ,” of the regular benefit formula for certain retired or disabled
workers who spent less than full careers in covered employment and who are also entitled to
pension benefits based on earnings from jobs not covered by Social Security. The reduction in
initial benefits caused by the WEP is designed to place affected workers in approximately the
same position they would have been in had all their earnings been covered by Social Security.
Background on the Social Security Benefit Formula
Workers qualify for Social Security benefits if they worked and paid Social Security payroll taxes
for a sufficient amount of time in covered employment.2 Retired workers need at least 40 earnings
credits (or about 10 years of covered work), whereas disabled workers general y need fewer
earnings credits.3 Initial benefits are based on a worker’s career-average earnings from jobs
covered by Social Security. In computing the initial benefit amount, a worker’s annual taxable
earnings are indexed (i.e., adjusted) to average wage growth in the national economy.4 This is
done to bring earlier years of earnings up to a comparable, current basis. Next, a summarized
measure of a worker’s career-average earnings is found by totaling the highest 35 years of
1 For the purposes of this report, the term payroll tax includes the Social Security self-employment tax.
2 Unless otherwise noted, the term covered employment includes self-employment covered by Social Security.
3 A worker may earn up to four earnings credits per calendar year. In 2021, a worker earns one credit for each $1,470 of
covered earnings, up to a maximum of four credits for covered earnings of $5, 880 or more. Earnings credits are also
called quarters of coverage. See Social Security Administration (SSA), How You Earn Credits, Publication No. 05-
10072, 2021, https://www.ssa.gov/pubs/EN-05-10072.pdf.
4 Years of earnings are indexed up to the second calendar year before the year of earliest eligibility (i.e., the year in
which the worker first attains aged 62, becomes disabled, or dies). Years of earnings after the last indexing year are
counted in nominal (i.e., unadjusted) dollars.

covered earnings and then dividing by 35.5 After that, a monthly average, known as average
indexed monthly earnings (AIME), is found by dividing the annual average by 12.
Once the worker’s AIME has been derived, it is then entered into the Social Security benefit
formula to produce the worker’s initial benefit amount. The benefit formula is progressive,
replacing a greater share of career-average earnings for low-paid workers than for high-paid
workers. The benefit formula applies three factors—90%, 32%, and 15%—to three different
levels, or brackets, of AIME. The result is known as the primary insurance amount (PIA) and is
rounded down to the nearest 10 cents. The PIA is the worker’s basic benefit before any
adjustments are applied.6 The benefit formula applicable to a given worker is based on the
individual’s earliest eligibility year (ELY), that is, the year in which the worker first attains age
62, becomes disabled, or dies.7 For workers whose ELY is 2021, the PIA is determined as follows
in Table 1.

Source: CRS, based on Social Security Administration (SSA), Office of the Chief Actuary (OCACT), “Benefit
Formula Bend Points,” https://www.ssa.gov/oact/cola/bendpoints.html.
The averaging provision in the benefit formula tends to cause workers with short careers in Social
Security-covered employment to have low AIMEs, even if they had high earnings in their
noncovered career. This results in these workers having AIMEs that are similar to those of people
who worked for low earnings in covered employment throughout their careers. This is because
years of zero covered earnings are entered as zeros into the formula that averages the worker’s
earnings history over 35 years. For example, a person with 10 years in Social Security-covered
employment would have an AIME that reflects 25 years of zero earnings, even if that person
worked for 25 years in a high-paying, noncovered career.
Consequently, for a worker whose AIME is low because his or her career was split between
covered and noncovered employment, the benefit formula replaces more of covered earnings at
the 90% rate than if the worker had spent a full 35-year career in covered employment at the same
earnings level. The higher replacement rate8 for workers who have split their careers between
Social Security-covered and noncovered jobs is sometimes referred to as a “windfal .”9
5 T he number of benefit computation years for disabled or deceased workers may be fewer than 35 years.
6 T he worker’s primary insurance amount (PIA) is subsequently adjusted to account for inflation through cost-of-living
adjustments (COLAs). Additional adjustments may be made to the PIA to account for early retirement, delayed
retirement, or certain other factors.
7 Although the factors in the formula are fixed in law, the dollar amounts defining the brackets, also known as bend
points, are adjusted annually for average earnings growth in the national economy. Because the bend points change
each year, the benefit formula for a worker with an earliest eligibility year (ELY) in 2021 is different from the benefit
formula for a worker with an ELY in any other year. For bend point amount for years prior to 20 21, see SSA, Office of
the Chief Actuary (OCACT ), “Benefit Formula Bend Points,” https://www.ssa.gov/oact/cola/bendpoints.html.
8 T he replacement rate is the ratio of the program benefit to a worker’s prior earnings.

How the Windfall Elimination Provision Works
A different Social Security benefit formula, known informal y as the windfall elimination
provision, applies to certain workers who are entitled to Social Security benefits as wel as to
pension benefits from employment not covered by Social Security.10 Under the WEP, the 90%
factor in the first bracket of the formula is reduced to as low as 40%. The effect is to lower the
proportion of earnings in the first bracket that are converted to benefits. Table 2 il ustrates how
the regular benefit formula and the WEP work in 2021 for someone with a 40% factor.

Note: PIA = Primary Insurance Amount. AIME = Average Indexed Monthly Earnings. By law, the PIA is rounded
down to nearest 10 cents.
In this scenario, the monthly benefit is $498.00 lower under the WEP than under the regular
benefit formula ($1,057.60 minus $559.60). Note that the WEP reduction is limited to the first
bracket in the AIME formula (90% vs. 40%), while the 32% and 15% factors for the second and
third brackets are unchanged. As a result, for AIME amounts that exceed the first formula
threshold of $996, the WEP reduction remains a flat $498 per month. For example, if the worker
had an AIME of $4,000 instead of $1,500, the WEP reduction would stil be $498 per month. The
WEP therefore causes a proportional y larger reduction in benefits for workers with lower AIMEs
and monthly benefit amounts.11
A guarantee in the WEP ensures that the WEP reduction cannot exceed half of the noncovered
pension based on the worker’s noncovered work. This guarantee is designed to help protect
workers with low pensions from noncovered work. The WEP does not apply to workers who have
30 or more years of substantial employment covered under Social Security, with an adjusted
reduces Social Security benefits paid to spouses and widow(er)s of insured workers if the spouse or widow(er) also
receives a pension based on government employment not covered by Social Security. See CRS Report RL32453, Social
Security: The Governm ent Pension Offset (GPO).

provision is not specified in statute or in SSA’s regulations.
11 For the worker shown in Table 2, with an AIME of $1,500 and a monthly benefit of $1,057.60 under the regular
benefit formula in 2021, the WEP reduction of $498.00 represents a cut of approximately 47% to the regular formula
monthly benefit amount. By comparison, a worker with an AIME of $4,000 would be e ntitled to a PIA of $1,857.60
under the 2021 regular benefit formula, and the same WEP reduction of $ 498.00 per month would represent a 27%
reduction in this worker’s monthly benefit amount.

Notes: The WEP reduction may be lower than the amount shown because the reduction is limited to one-half
of the worker’s pension from noncovered employment. In addition, because the WEP reduces the initial benefit
amount before it is reduced or increased due to early retirement, delayed retirement credits (DRCs), cost-of-
living adjustments (COLAs), or other factors, the difference between the final benefit with the WEP and the final
benefit without the WEP may be less than or greater than the amounts shown.
a. The maximum dol ar amount of the monthly WEP reduction is based on a worker’s ELY. Because the dol ar
amounts defining the brackets in the benefit formula change each year, the maximum dol ar amount of the
WEP reduction for a worker with an ELY of 2021 is different from the maximum deduction for a worker
with an ELY of any other year. For maximum WEP reduction amounts for workers with ELYs prior to
2021, see SSA, “Windfal Elimination Provision (WEP) Chart,” https://www.ssa.gov/planners/retire/wep-
chart.html.
The WEP applies to benefits payable to retired or disabled workers who meet the criteria above
and to their eligible dependents; however, it does not apply to benefits payable to survivors of
deceased insured workers. Groups of workers likely to be affected by the WEP include certain
state and local government employees who are covered by alternative pension plans through their
employers13 and most permanent civilian federal employees hired before January 1, 1984, who
are covered by the Civil Service Retirement System (CSRS).14 The WEP does not apply to
federal employees performing service on January 1, 1984, to which coverage was
extended on that date by reason of the Social Security Amendments of 1983 (P.L.
98-21);
12 For determining years of coverage after 1978 for individuals with pensions from noncovered employment,
“substantial coverage” is defined as 25% of the “old law” Social Security maximum taxable earnings base for each year
in question. T he old law maximum t axable earnings base refers to the earnings base that would have been in effect had
the Social Security Amendments of 1977 (P.L. 95-216) not been enacted. In 2021, the old-law taxable earnings base is
equal to $106,200; therefore, to earn credit for one year of substantial employment under the WEP, a worker would
have to earn at least $26,550 in Social Security-covered employment. For the thresholds for previous years, see SSA,
OCACT , “Old-Law Base and Year of Coverage,” https://www.ssa.gov/oact/cola/yoc.html.

coverage on December 31, 1983, and who became covered for the first time on
January 1, 1984, under P.L. 98-21;

The Number of People Affected by the WEP
According to the Social Security Administration (SSA), as of December 2020, about 1.9 mil ion
Social Security beneficiaries were affected by the WEP (Table 4). The overwhelming majority of
those affected (about 94%) were retired workers. Approximately 3% of al Social Security
beneficiaries (including disabled workers and dependent beneficiaries) and 4% of al retired-
worker beneficiaries were affected by the WEP in December 2020.18 Of retired workers affected
by the WEP, approximately 56% were men (Table 5).

Legislative History and Rationale
The WEP was enacted in 1983 as part of major amendments (P.L. 98-21) designed to shore up the
financing of the Social Security program. The 40% WEP formula factor was the result of a
compromise between a House bil that would have substituted a 61% factor for the regular 90%
factor and a Senate proposal that would have substituted a 32% factor.19
The purpose of the 1983 provision was to remove an unintended advantage that the regular Social
Security benefit formula provided to certain retired or disabled worker-beneficiaries who were
also entitled to pension benefits based on earnings from jobs not subject to the Social Security
payroll tax. The regular formula was intended to help workers who spent their lifetimes in low-
paying jobs, by providing them with a benefit that replaces a higher proportion of their career-
average earnings than the benefit provided to workers with high career-average earnings.
However, the formula does not differentiate between those who worked in low -paid jobs
throughout their careers and other workers who appear to have been low paid because they
worked many years in jobs not covered by Social Security and few years in covered jobs. Under
the old law, workers who were employed for only a portion of their careers in jobs covered by
Social Security—even highly paid ones—also received the advantage of the weighted formula,
because their few years of covered earnings were averaged over their entire working career to
determine the average covered earnings on which their Social Security benefits were based. The
WEP is intended to place affected workers in approximately the same position they would have
been in had all their earnings been covered by Social Security.

Social Security: The Windfall Elimination Provision (WEP)
Arguments for the WEP
Proponents of the measure say that it is a reasonable means to prevent payment of overgenerous
and unintended benefits to certain workers who otherwise would profit from happenstance (i.e.,
the mechanics of the Social Security benefit formula). Furthermore, they maintain that the
provision rarely causes hardship because by and large the people affected are reasonably wel off
because by definition they also receive pensions from noncovered work. The guarantee provision
ensures that the reduction in Social Security benefits cannot exceed half of the pension from
noncovered work, which protects people with smal pensions from noncovered work. In addition,
the impact of the WEP is reduced for workers who spend 21 to 29 years in Social Security-
covered work and is eliminated for people who spend 30 years or more in Social Security-
covered work.
Arguments Against the WEP
Some opponents believe the provision is unfair because it substantial y reduces a benefit that
workers may have included in their retirement plans. Others criticize how the provision works.
They say the arbitrary 40% factor in the windfal elimination formula is an imprecise way to
determine the actual windfal when applied to individual cases.20
The WEP’s Impact on Low-Income Workers
The impact of the WEP on low-income workers has been the subject of debate. Jeffrey Brown
and Scott Weisbenner (hereinafter “Brown and Weisbenner”) point out two reasons why the WEP
can be regressive.21 First, because the WEP adjustment is confined to the first bracket of career-
average earnings in the benefit formula ($996 in 2021), it causes a proportional y larger reduction
in benefits for workers with lower AIMEs and benefit amounts. Second, a high earner is more
likely than a low earner to cross the “substantial work” threshold for accumulating years of
covered earnings (in 2021 this threshold is $26,550 in Social Security-covered earnings);
therefore, high earners are more likely to benefit from the provision that phases out the WEP for
people with between 21 and 29 years of covered employment.
Brown and Weisbenner found that the WEP does reduce benefits disproportionately for lower-
earning households.22 For some high-income households, applying the WEP to covered earnings
even provides a higher replacement rate than if the WEP were applied proportionately to al
earnings, covered and noncovered. Brown and Weisbenner found that the WEP can also lead to
large changes in Social Security replacement rates based on smal changes in covered earnings,
particularly when a smal increase in covered earnings carries a person over the threshold for an
additional year of substantial covered earnings, leading to an adjustment in the WEP formula
applied to the AIME.

Social Security: The Windfall Elimination Provision (WEP)
Noncovered Pensions for Beneficiaries Affected by
the WEP
The WEP applies to Social Security beneficiaries who are entitled to (i.e., receiving) a pension
based on earnings that were not covered by Social Security. SSA periodical y provides data on
those noncovered pension amounts for Social Security beneficiaries affected by the WEP. Figure
1 shows the distribution of Social Security WEP-affected beneficiaries who first became eligible
for benefits in 2017, by noncovered pension amount and gender. As of December 2020, about
21% of those beneficiaries received a noncovered pension amount less than $1,000 per month,
approximately 52% received a monthly amount between $1,000 and $3,999, and 27% received a
monthly amount of $4,000 or more. Among those WEP-affected beneficiaries, women tended to
have a lower noncovered pension amount than men on average.

Noncovered Pension Amount and Gender, December 2020

Notes: Data reflects beneficiaries for whom noncovered pension amounts are available. The monthly pension
amount represents the noncovered government pension amount at the time of initial filing for Social Security
benefits.
A worker who split his or her career between Social Security-covered and noncovered jobs may
receive both Social Security retired-worker benefits (subject to the WEP) and a noncovered
pension. In December 2020, among al Social Security worker beneficiaries who were affected by
the WEP, about 82% had 20 or fewer YOCs (substantial covered earnings under Social
Security).23 Usual y, the longer the individual worked in noncovered employment, the shorter the
employment in covered jobs (provided that the number of working years a person can work is
relatively stable). In this case, the worker would be likely to receive a relatively larger
noncovered pension amount and a smal er Social Security benefit. In December 2020, among
WEP-affected beneficiaries who first became eligible for Social Security in 2017, about 38% of

them received a monthly noncovered pension amount of $2,000 or more and a monthly Social
Security benefit below $600 after the effect of the WEP (see Figure 2).
However, some workers may work a relatively short career or at relatively low earnings in both
Social Security-covered and noncovered jobs, thus resulting in relatively low combined Social
Security and noncovered pension benefits. In December 2020, among WEP-affected beneficiaries
who became eligible for Social Security in 2017, about 11% of those beneficiaries received less
than $1,000 per month in noncovered pensions and less than $900 per month in Social Security
benefits (for a combined total below $1,900 per month). Another 9% received between $1,000-
1,999 per month in noncovered pensions and less than $600 per month in Social Security (for a
combined total greater than $1,000 and below $2,599 per month). This monthly benefit amount
does not include retirement income received from other sources (such as need-based benefits and
other government transfers, earnings, retirement savings, and asset income).

Recent Legislation on the WEP
Over the years, legislation has been introduced that would repeal or make changes to the WEP.
This section summarizes legislation introduced in the 116th Congress and the 117th Congress to
date.
Legislative Activity on the WEP in the 116th Congress
In the 116th Congress, several proposals were introduced that would have repealed, replaced, or
amended the WEP. None of these proposals was acted upon. These proposals are briefly
described below.
Congressional Research Service
10
Social Security: The Windfall Elimination Provision (WEP)
H.R. 141 (the Social Security Fairness Act of 2019) and its companion bil , S. 521, were
introduced by Representative Rodney Davis on January 3, 2019, and Senator Sherrod Brown on
February 14, 2019, respectively. The legislation would have repealed the WEP and the
government pension offset (GPO), which reduces the Social Security benefits paid to spouses and
widow(er)s of insured workers if the spouse or widow(er) also receives a pension based on
government employment not covered by Social Security.24 The elimination of the WEP and GPO
would have applied to benefits payable for months after December 2019. In 2016 (the most recent
estimate available), SSA’s Office of the Chief Actuary (OCACT) projected that repealing both
the WEP and the GPO would reduce the long-range actuarial balance (i.e., increase the net long-
term cost) of the combined Social Security trust funds by 0.13% of taxable payroll.25 The
OCACT estimated that repealing only the WEP would reduce the long-range actuarial balance of
the combined trust funds by 0.08% of taxable payroll.26
S. 710 (the Social Security Fairness for Firefighters and Police Officers Act) was introduced by
Senator Pat Toomey on March 7, 2019. The bil would have exempted certain firefighters and
police officers with five years of qualified service from the WEP and the GPO.27
Since 2004, legislation has reflected a different approach that would replace the WEP formula
under current law with a new proportional formula for new beneficiaries. Under this approach,
the proportional formula would apply the regular Social Security benefit formula to al past
earnings from covered and noncovered employment. The resulting benefit would then be reduced
by the ratio of career-average earnings from covered employment to career-average earnings from
both covered and noncovered employment (i.e., combined earnings). Based on the estimate from
OCACT, among al current beneficiaries in 2018, about 69% of those affected by the WEP would
receive an increase in Social Security benefits using the proportional formula, and the remaining
31% would receive a lower benefit. In addition, 13.5 mil ion beneficiaries who are not affected by
the current WEP would receive a lower benefit using the proportional formula.28 Most workers
who are not affected by the current WEP but would be affected by the proportional formula are
those with noncovered employment who have 30 or more years of substantial covered earnings,
or those with noncovered employment who are not receiving noncovered pension benefits; both
groups are exempt from the WEP under current law. To protect future beneficiaries from further
benefit reduction compared with the current law, the recent legislation based on the proportional
formula would have general y attempted to hold beneficiaries harmless to a certain degree by
providing the higher benefit of the current-law WEP or the proportional formula. This approach
was reflected in the Equal Treatment of Public Servants Act (H.R. 3934 and S. 3401 in the 116th
Congress and H.R. 5834 in the 117th Congress) and the Public Servants Protection and Fairness

Act (H.R. 4540 in the 116th Congress and H.R. 2337 in the 117th Congress), as described below in
this section and the section “Legislative Activity on the WEP in the 117th Congress.”
H.R. 3934 (the Equal Treatment of Public Servants Act) and its companion bil , S. 3401, were
introduced by Representative Kevin Brady on July 24, 2019, and by Senator Ted Cruz on March
5, 2020, respectively. The legislation would have replaced the WEP with a new proportional
formula for individuals who become eligible for Social Security benefits in 2022 or later.
Individuals becoming eligible between 2022 and 2060 would receive the higher of their benefit
under the current-law WEP or the proportional formula. The proposal would have also provided a
rebate payment starting in 2020 for workers (up to $100 per month) and their dependents (up to
$50 per month) affected by the current WEP. The rebate payments would have increased with
cost-of-living adjustments. In 2019, OCACT estimated that the legislation would increase
program cost by about $23.1 bil ion (mainly from the rebate) over the period 2020 through 2029,
and would have no significant effect on the Social Security trust funds’ long-range (75 years)
actuarial balance.29
H.R. 4540 (the Public Servants Protection and Fairness Act) was introduced by Representative
Richard E. Neal on September 27, 2019. Similar to H.R. 3934, the legislation would have
replaced the WEP with the new proportional formula for individuals who become eligible for
Social Security benefits in 2022 or later. However, unlike H.R. 3934, al individuals who become
eligible in 2022 or later would have received the higher of their benefit under the current-law
WEP or the proportional formula. Also, as under current law, workers with 30 or more years of
substantial earnings and those not receiving noncovered pension benefits would be exempt from
the WEP. The proposal would have provided a rebate payment starting nine months after
enactment for retired-worker and disabled-worker beneficiaries affected by the current WEP (up
to $150 per month), but not for their dependents. The rebate payments would have increased with
cost-of-living adjustments. The proposal’s cost would be covered by transfers from general
revenues. In 2019, OCACT estimated that the legislation would increase program expenditures by
about $34.3 bil ion (mainly from the rebate) between 2020 and 2029, which would be reimbursed
from the General Fund of the U.S. Treasury. In the long run (75 years), the projected program
cost would increase by an amount equal to 0.02% of taxable payroll, and the projected program
income would increase by the same amount with transfers from the General Fund, thus having no
significant effect on the combined trust funds’ actuarial balance.30
In addition, H.R. 5529 (the Social Security Equity Act of 2019) was introduced by Representative
Adam Smith on December 19, 2019. The bil would have changed the current-law WEP formula
such that the WEP benefit reduction for most affected workers would be lower relative to current
law.31
Legislative Activity on the WEP in the 117th Congress
The Social Security Fairness Act was reintroduced by Representative Rodney Davis on January 4,
2021 (H.R. 82), and Senator Sherrod Brown on April 22, 2021 (S. 1302), respectively. The

the 2019 Social Security trustees report.
31 H.R. 5529 would have revised the current WEP formula for the PIA computation to (1) lower from 30 to 25 the
number of years of coverage required for exemption from the WEP; (2) alter the determination of partial exemptions
for those who have more than 20 but less than 25 years of coverage; and (3) reduce the amount of earnings required for
a year of coverage (i.e., lower the “ substantial earnings” threshold for a year of coverage).

legislation would repeal the WEP and the GPO for benefits payable for months after December
2021. (See H.R. 141 in the 116th Congress, described above.) In addition, the bil s titled Social
Security 2100: A Sacred Trust were introduced by Representative John B. Larson (H.R. 5723) and
Senator Richard Blumenthal (S. 3071), respectively, on October 26, 2021. Among other
provisions, the bil s would repeal the WEP and the GPO for benefits payable during 2022 through
2026.
While some bil s would repeal the WEP, others would replace the WEP with a new proportional
formula (as described in the section “Legislative Activity on the WEP in the 116th Congress”).
The Public Servants Protection and Fairness Act (H.R. 2337) was reintroduced by Representative
Richard E. Neal on April 1, 2021, and the Equal Treatment of Public Servants Act (H.R. 5834)
was reintroduced by Representative Kevin Brady on November 3, 2021. In both cases, the
legislation would apply to individuals who become eligible for Social Security benefits in 2023 or
later.
H.R. 2337 (Representative Neal) includes a benefit guarantee provision that would al ow
individuals to receive the higher of their benefit under the current-law WEP or the proportional
formula. The proposal would also provide a rebate payment starting nine months after enactment
for retired-worker and disabled-worker beneficiaries affected by the current WEP (up to $150 per
month); the rebate payments would increase with cost-of-living adjustments. In 2021, OCACT
estimated that the legislation would increase program expenditures by about $30.6 bil ion (mainly
from the rebate) between 2021 and 2030. The change in net cash flow of $29.0 bil ion (net of the
revenue from income taxation on benefits) would be reimbursed from the General Fund of the
U.S. Treasury. In the long run (75 years), the projected program cost would increase by an
amount equal to 0.02% of taxable payroll, and the projected program income would increase by
the same amount with transfers from the General Fund, thus having no significant effect on the
combined trust funds’ actuarial balance.32
H.R. 5834 (Representative Brady) would al ow individuals becoming eligible during the
transitional period between 2023 and 2061 to receive the higher of their benefit under the current-
law WEP or the proportional formula. For those who become eligible in 2062 and later, benefits
would be based solely on the proportional formula. The proposal would also provide a rebate
payment starting nine months after enactment for workers (up to $100 per month) and their
dependents (up to $50 per month) affected by the current WEP. The rebate payments would
increase with cost-of-living adjustments. In 2021, OCACT estimated that the legislation would
increase program costs by about $27.7 bil ion (or $26.3 bil ion net of the revenue from the
income taxation on benefits) over the period 2022 through 2031. According to OCACT’s
estimates, over the 75-year projection period, future savings from the proportional formula would
offset the cost of the monthly rebate payments and the protection provision during the transitional
period, so the bil would have no significant effect on Social Security’s long-term financial
outlook.33
The Wel being for Every Public Servant Act of 2021 (H.R. 4788) was introduced by
Representative Julia Letlow on July 29, 2021. Under the legislation, individuals whose combined
monthly benefits from Social Security and noncovered public pensions are below a wage-indexed

amount of $5,500 would be exempt from the WEP. Beneficiaries whose combined monthly
benefits from Social Security and noncovered public pensions are between $5,500 and $6,333
would be subject to a partial WEP reduction. The legislation would apply to benefits payable for
months after the enactment of this act.
