    shortfall depending on workersshortfall depending on workers' characteristics and specific benefit plan designs. Moreover, underfunding and the possibility of a few plans exhausting their trust fund assets reinforce the findings regarding benefit generosity."70 At the same time, the study acknowledges that Social Security also faces projected funding shortfalls, which can complicate comparisons of benefit generosity. With respect to ensuring Social Security–equivalent protections for all state and local government employees, the CRR researchers note that one option would be to update the safe harbor requirements for defined benefit plans to specify "reasonable" vesting periods and provide full COLAs. Another option would be to bring all state and local government employees into the Social Security system.71 Social Security Benefits for Individuals with Noncovered Earnings

    The current-law Social Security benefit formula may provide unintended overgenerous benefits to individuals who had earnings from jobs not covered under Social Security. Workers with limited Social Security-covered earnings but substantial noncovered earnings usually (1) qualify for a pension based on noncovered earnings (also known as a noncovered pension) and (2) appear to be low earners or dependents (e.g., spouses or widow[er]s) under the Social Security system. (Noncovered earnings are shown as zeros in Social Security-covered earnings records.) Because the Social Security benefit formula is progressive, it can provide likely unintended overgenerous benefits to many workers who have substantial noncovered earnings.

    In the past, the Windfall Elimination Provision (WEP) and the Government Pension Offset (GPO) were two separate provisions that intended to approximately remove these "overgenerous" benefits to beneficiaries who were also entitled to a noncovered pension. That is, the provisions were designed to place Social Security beneficiaries who had some noncovered earnings in approximately the same position they would have been in had all their earnings been covered by the program. Beginning in January 2024, the WEP and GPO reductions are no longer applied to Social Security benefits.72 Approximately two-thirds of WEP and GPO cases involved former state and local government employees.73 Mandatory Social Security coverage for newly hired state and local government employees would eventually eliminate these benefit advantages.

    Social Security Coverage of State and Local Government Employees

    underfunding and the possibility of a few plans exhausting their trust fund assets reinforce the
    findings regarding benefit generosity.”66 At the same time, the study acknowledges that Social
    Security also faces projected funding shortfalls, which can complicate comparisons of benefit
    generosity. With respect to ensuring Social Security–equivalent protections for all state and local
    government employees, the CRR researchers note that one option would be to update the safe
    harbor requirements for defined benefit plans to specify “reasonable” vesting periods and provide
    full COLAs. Another option would be to bring all state and local government employees into the
    Social Security system.67
    Windfall Elimination Provision and Government Pension Offset
    The Social Security program includes two provisions that affect beneficiaries who receive
    pensions from work that was not covered by Social Security: the Windfall Elimination Provision
    (WEP) and the Government Pension Offset (GPO). These provisions were enacted by Congress . These provisions were enacted by Congress
    to address equity issues created by the exclusion of to address equity issues created by the exclusion of workers from Social Security coverage (e.g., some state and local government employeessome state and local government employees

    worker) as well as the benefits paid to his or her eligible family members. The GPO, which was worker) as well as the benefits paid to his or her eligible family members. The GPO, which was

    received as the spouse or surviving spouse of a Social Securityas the spouse or surviving spouse of a Social Security-covered worker.74 The Social Security Fairness Act of 2023 (SSFA, P.L. 118-273), signed into law on January 5, 2025, repealed both provisions for monthly benefits payable after December 2023.

    From 1984 to 2023, the WEP reduced Social Security benefits of certain retired or disabled workers (and their family members) who were also entitled to pension benefits based on earnings from noncovered jobs (including certain foreign pensions). The Social Security benefit formula is intended to help workers who spend their careers in low-paying jobs by providing them with relatively higher benefits in relation to their career-average earnings in covered employment than the benefits for workers with high career-average earnings. However, the formula could not differentiate between those who worked in low-paid jobs throughout their careers and other workers who appeared to have been low paid because they worked many years in jobs not covered by Social Security. The WEP was aimed to remove this windfall that these latter beneficiaries would otherwise have received from Social Security.

    From 1977 to 2023, the GPO adjusted the Social Security spousal or widow(er) benefits of most people who also received federal, state, or local government pensions based on earnings not covered by Social Security. The GPO was intended to replicate the dual entitlement rule for beneficiaries whose entire careers were covered by the program
    covered worker.68
    Windfall Elimination Provision (WEP)
    The WEP affects people who have worked in both covered and noncovered employment. If a
    person is receiving a pension from noncovered employment, his or her Social Security benefits
    are subject to reduction under the WEP if he or she has fewer than 30 years of substantial
    earnings in covered employment.69 Under the WEP, the worker’s Social Security benefits are
    computed using an alternative benefit formula (the “windfall formula”) rather than the regular
    benefit formula. The windfall formula results in a lower initial monthly benefit. The amount of
    the reduction in the initial monthly benefit is limited to one-half the monthly amount of the
    worker’s noncovered pension.
    The regular benefit formula has a progressive structure intended to help workers with long careers
    in covered employment at lower wages. That is, compared to higher earners, lower-wage workers
    receive initial monthly benefits that replace a larger percentage of their career-average earnings.70

    66 Quinby, Aubry, and Munnell, “Do Public Workers Without Social Security Get Comparable Benefits?,” p. 4. CRR
    published another two related studies thereafter. One study found that medium-tenure workers (6 to 20 years of tenure)
    who spent the early part of their career in noncovered government employment were at most risk, representing about
    16% of noncovered public workers (or between 750,000 to 1 million annually). See Jean-Pierre Aubry et al., “What
    Share of Noncovered Public Employees Will Earn Benefits that Fall Short of Social Security?,” CRR, April 2022,
    https://crr.bc.edu/wp-content/uploads/2022/04/wp_2022-4.pdf. The other study using four different datasets found that
    around one-third of noncovered workers fell into the medium-tenure group. See Jean-Pierre Aubry et al., “How Many
    Public Workers Without Social Security Could Fall Short?,” CRR, April 2022, https://crr.bc.edu/wp-content/uploads/
    2022/03/SLP82.pdf.
    67 Quinby, Aubry, and Munnell, “Do Public Workers Without Social Security Get Comparable Benefits?,” p. 5.
    68 The WEP was enacted as part of the Social Security Amendments of 1983 (P.L. 98-21). The GPO was enacted as
    part of the Social Security Amendments of 1977 (P.L. 95-216) and modified as part of the Social Security Amendments
    of 1983 (P.L. 98-21).
    69 The reduction under the WEP is phased out for workers with between 21 and 30 years of substantial earnings in
    covered employment. Workers with 30 or more years of substantial earnings in covered employment are exempt from
    the WEP.

    (sometimes at higher wages) because they also worked in noncovered employment and receive a
    pension based on noncovered work. In December 2023, about 2.1 million Social Security
    beneficiaries (about 3% of all beneficiaries) were affected by the WEP.71
    Government Pension Offset (GPO)
    The GPO affects people who have worked in noncovered government employment and also
    qualify for Social Security benefits as the spouse or surviving spouse of a Social Security–
    covered worker. If a person is receiving a government pension from noncovered employment, his
    or her Social Security spousal or widow(er) benefits are subject to reduction under the GPO. The
    person’s Social Security spousal or widow(er) benefits are reduced by an amount equal to two-
    thirds of his or her noncovered pension (a two-thirds offset). Depending on the relative amounts
    of the two benefits, the Social Security spousal or widow(er) benefits may be reduced to zero. In
    December 2023, 745,679 Social Security beneficiaries (about 1% of all beneficiaries) were
    affected by the GPO.72
    The GPO is intended to replicate the Social Security dual entitlement rule, which affects people
    who have worked in covered employment and also qualify for Social Security benefits as the
    spouse or surviving spouse of a Social Security–covered worker. Under the dual entitlement rule,
    the person’. Under the dual entitlement rule, a person's Social Security spousal or widow(er) s Social Security spousal or widow(er) benefits arebenefit is reduced by the reduced by the full amount of his amount of his

    the two benefits, the Social Security spousal or widow(er) benefits may be reduced to zero.
    Issues Related to the WEP and the GPO
    Approximately two-thirds of WEP and GPO cases involve former state and local government
    employees.73 A person who is applying for benefits, or a person who is already receiving benefits,
    must inform SSA that he or she is receiving a pension from noncovered employment and the
    amount of the pension so that the WEP and the GPO can be applied to the Social Security benefit
    computation. (One or both provisions may apply depending on the circumstances.) SSA must
    generally rely on self-reported data to administer the WEP and the GPO for state and local
    government employees, which can make enforcement of the provisions difficult and can result in
    overpayments.74 In addition, inconsistent reporting by individuals can raise equity issues. If
    individuals do not accurately report their noncovered pension information to SSA, they may
    receive higher Social Security benefits than they are due under current law. A recent study found
    that the number of state and local government employees in jobs not covered by Social Security
    increased from 4.2 million in the 1994-1998 period to 4.7 million in the 2014-2018 period. This
    trend suggests an increase in SSA workloads in the future to administer the WEP and the GPO.75

    In addition, critics point out that these provisions are not well understood by the people who are
    affected by them.76 They further point out that affected individuals considera 100% offset). The GPO reduced certain individuals' Social Security spousal or widow(er) benefits by two-thirds of their noncovered government pensions (i.e., a 67% offset). The GPO was designed to place spouses and widow(er)s who received noncovered government pensions in approximately the same position as spouses and widow(er)s whose entire careers were covered by Social Security. Supporters of the WEP and GPO said that the provisions were reasonable means to prevent overgenerous benefits to certain people due to their noncovered employment. However, critics pointed out that these provisions were not well understood. They argued that many people affected by the provisions were unprepared for smaller Social Security benefits than they had expected in making retirement plans. They further pointed out that affected individuals considered the provisions to be the provisions to be

    To qualify as an alternative to Social Security, the public retirement system must provide a minimum level of benefits. In general, it must provide a retirement benefit that is comparable to Social Security.

    20.

    Data from SSA obtained by CRS in February 2026.

    21.

    As noted in SSA's POMS, "Ultimately, it is within the state's discretion to determine for whom, whether, and when to extend Section 218 coverage, subject to the requirements of the [Social Security] Act" (POMS, Section SL 30001.301, Section 218 Agreements, Paragraph C, https://secure.ssa.gov/apps10/poms.nsf/lnx/1930001301#c).

    22.

    Under Section 210(a) of the Social Security Act (42 U.S.C. §410(a)), certain categories of employees are not subject to mandatory Social Security coverage, including state and local government employees who fall within these categories. For example, services performed by individuals hired to be relieved from unemployment are not subject to mandatory Social Security coverage. For more information, see IRS Publication 963, Federal-State Reference Guide, Revised July 2020, Chapter 5: Social Security and Medicare Coverage, pp. 44-45, https://www.irs.gov/pub/irs-pdf/p963.pdf.

    23.

    Medicare payroll taxes generally apply to all wages (not limited by the taxable maximum) of all state and local government employees hired or re-hired after March 31, 1986, unless specifically excluded under Section 210(p) of the Social Security Act (42 U.S.C. §410(p)). This requirement was mandated by the Consolidated Omnibus Budget Reconciliation Act (COBRA) of 1985 (P.L. 99-272). See IRS Publication 963, pp. 49-50.

    24.

    A traditional defined benefit formula would be: annual benefit = an accrual rate X the number of years of service X the average of the worker's final years of salary. The accrual rate is a percentage factor typically ranging from 2% to 3% in most traditional defined benefit plans.

    27.

    In the Social Security program, the worker's PIA is the benefit payable at full retirement age (FRA), before any applicable adjustments are taken into account.

    28.

    The Social Security FRA is the age at which full (unreduced) Social Security retirement benefits are first payable. The FRA ranges from 65 to 67, depending on the worker's year of birth. Workers born in 1960 or later have an FRA of 67. Retirement benefits are payable as early as age 62, but benefits claimed between age 62 and the FRA are permanently reduced to take into account "early retirement."

    The term state includes the 50 states, the Commonwealth of Puerto Rico, and the U.S. Virgin Islands. It also includes interstate instrumentalities. An interstate instrumentality is an independent legal entity organized by two or more states to carry out one or more governmental functions, such as police power, taxing power, and/or power of eminent domain. For example, the New Jersey–New York Port Authority is an interstate instrumentality. Approximately 60 interstate instrumentalities have Section 218 Agreements with SSA (IRS Publication 963, p. 1).

    38.

    Those who oppose mandatory Social Security coverage for newly hired state and local government employees sometimes argue that it would raise constitutional issues and might be challenged in court. In 1998, the General Accounting Office (now the Government Accountability Office) wrote, "we believe that mandatory coverage is likely to be upheld under current U.S. Supreme Court decisions." See GAO, Social Security: Implications of Extending Mandatory Coverage to State and Local Employees, GAO/HEHS-98-196, August 1998, pp. 19-20, http://www.gao.gov/archive/1998/he98196.pdf. A discussion of any potential legal issues associated with mandatory coverage for newly hired state and local government employees is beyond the scope of this CRS report.

    39.

    Coverage was extended to the U.S. Virgin Islands on an automatic basis. Puerto Rico had to elect coverage. The 1950 amendments permitted coverage to be extended to Puerto Rico provided the governor of Puerto Rico certified to the President of the United States that the legislature of Puerto Rico resolved (via concurrent resolution) to elect the extension. Social Security coverage became effective in Puerto Rico and the U.S. Virgin Islands on January 1, 1951.

The 23 states authorized to hold divided vote referendums are listed in Section 218(d)(6)(C) of the Social Security Act (42 U.S.C. §418(d)(6)(C)). In addition, under Section 218(g)(2) of the Social Security Act (42 U.S.C. §418(g)(2)), all interstate instrumentalities may divide a retirement system based on whether the employees in positions under that system want coverage.

    These workers did not have Social Security coverage based on their state and local government employment. In some cases, they may have Social Security coverage based on other employment, or they may have a family connection to a Social Security–covered worker that makes them potentially eligible for Social Security spousal benefits, for example.

For example, IRS Revenue Procedure 91-40 outlines a set of safe harbor formulas for defined benefit retirement systems. Benefits calculated under one of these formulas are deemed to meet the minimum retirement benefit requirement. In addition, procedures are set out by which an employer may determine whether retirement benefits calculated under other formulas meet the minimum retirement benefit requirement of the regulations with respect to an employee.

    Quinby, Aubry, and Munnell, "Do Public Workers Without Social Security Get Comparable Benefits?," p. 4. CRR published another two related studies thereafter. One study found that medium-tenure workers (6 to 20 years of tenure) who spent the early part of their career in noncovered government employment were at most risk, representing about 16% of noncovered public workers (or between 750,000 to 1 million annually). See Jean-Pierre Aubry et al., "What Share of Noncovered Public Employees Will Earn Benefits that Fall Short of Social Security?," CRR, April 2022, https://crr.bc.edu/wp-content/uploads/2022/04/wp_2022-4.pdf. The other study using four different datasets found that around one-third of noncovered workers fell into the medium-tenure group.

Defined contribution plans do not provide guarantees of lifetime income unless participants purchase an annuity. In any case, these plans do not guarantee a certain level of account assets or monthly annuity payable from the account.
