Government Pensions and SSDI Work Credits

Under Sections 210 and 218 of the Social Security Act, some state, county, and municipal employees participate in public pension plans while working in positions that are not covered by Social Security. If you work as a public school teacher, civil servant, police officer, or firefighter in a non-covered position, those earnings do not accumulate Social Security work credits toward SSDI disability insured status.

Public employees may assume that steady government service will protect them if a career-ending illness or injury occurs. However, Social Security Disability Insurance (SSDI) is an earned benefit tied to work covered by Social Security taxes. When public employees discover they do not qualify for federal disability payments, it may be because their state or local position was excluded from Social Security coverage.

Covered vs. Non-Covered Public Employment

In the private sector, most employment is covered under 20 CFR 404.1004. In 2026, employers and workers generally each pay a 6.2 percent Social Security tax under the Federal Insurance Contributions Act (FICA), which helps fund retirement, survivor, and disability benefits.

Public employment follows a different historical framework. When Congress created the Social Security program in 1935, state and local government employees generally were excluded from coverage. In 1950, Congress added Section 218 to the Social Security Act, allowing states to enter agreements with the Social Security Administration to extend coverage to eligible groups of public employees.

Many government employers obtained Social Security coverage through Section 218 agreements or other provisions of federal law. Other public employees remain in positions covered by independent retirement systems but not by Social Security. When wages from a position are excluded from Social Security taxation, those wages generally are classified as non-covered earnings and do not generate Social Security work credits.

Which Public Workers Are Typically in Non-Covered Systems?

Non-covered employment is concentrated in particular states, professions, and government agencies. Some public school teachers, police officers, firefighters, and other state or local employees work in positions excluded from Social Security coverage. Coverage can differ among employee groups and employers within the same state.

Public retirement systems that may include employees in non-covered positions include:

• The California State Teachers' Retirement System (CalSTRS).
• The Teacher Retirement System of Texas (TRS).
• The State Teachers Retirement System of Ohio (STRS Ohio).
• Certain state police, highway patrol, and municipal firefighter pension funds.
• Certain local county and municipal civil service retirement systems.
• The Civil Service Retirement System (CSRS) for eligible federal employees generally hired before January 1, 1984.

Membership in one of these systems does not by itself establish whether a particular job is covered by Social Security. Workers should verify their coverage through their payroll records, Social Security Statement, employer, and retirement-system administrator. Disability or retirement benefits associated with the public position generally are administered under the applicable government pension plan rather than the SSDI program.

How Non-Covered Employment Affects Work Credits

Social Security work credits, called quarters of coverage under 20 CFR 404.140, help determine insured status. In 2026, a worker earns one credit for each $1,890 in covered earnings, up to four credits after earning $7,560 during the year. In 2025, one credit required $1,810 in covered earnings, with four credits earned after $7,240.

Wages excluded from Social Security coverage do not earn Social Security work credits. A public school teacher who works for 25 consecutive years entirely in a non-covered position would receive no Social Security credits from those wages.

The worker may still have credits from other covered employment. However, payment of income taxes, regular attendance, or years of service in a non-covered position does not add covered earnings to the worker's Social Security record. Whether the person is insured for Title II disability benefits depends on their age, covered work history, and the date SSA determines the disability began.

The Problem of Split Careers and the 20/40 Rule

Many government workers had earlier careers in the private sector before entering public service. Past FICA contributions may provide Social Security credits, but disability insured status can expire when a worker stops performing covered work.

For many claimants age 31 or older, 20 CFR 404.130 requires at least 20 quarters of coverage during the 40-quarter period ending with the quarter disability began. Different rules can apply to younger workers and in certain other circumstances.

Consider an individual who worked for twelve years in private corporate accounting and then became a public school teacher in a non-covered position. As quarters without covered earnings enter the applicable measurement period, older covered quarters eventually fall outside it.

After enough time in non-covered employment, the teacher may reach a Date Last Insured (DLI). If SSA determines that the teacher's disability began after that date, the prior private-sector credits ordinarily will not establish current disability insured status. If the evidence establishes that disability began on or before the DLI, the worker may still qualify even if the application was filed later.

Medicare Qualified Government Employment (MQGE)

Many state and local government employees whose jobs are excluded from Social Security are nevertheless covered by Medicare. Federal law generally requires Medicare coverage for state and local government employees hired or rehired after March 31, 1986, unless an exception applies. In 2026, employees and employers generally each pay a 1.45 percent Medicare tax on covered wages, with an additional employee Medicare tax potentially applying above the statutory earnings threshold.

Work covered for Medicare but not for Social Security cash benefits is commonly called Medicare Qualified Government Employment (MQGE). SSA maintains separate rules for determining whether Medicare-covered government work can establish disability-based Medicare eligibility.

MQGE does not ordinarily earn credits toward monthly SSDI cash benefits. It may, however, help a qualifying disabled worker establish eligibility for Medicare based on disability. Medicare coverage is subject to SSA's entitlement and waiting-period rules, including any applicable exceptions, so workers should request an individualized determination from SSA.

Pension Reductions: WEP and GPO

Federal law previously included two provisions that could reduce Social Security benefits for people receiving pensions based on work not covered by Social Security.

The Windfall Elimination Provision (WEP) modified the benefit-computation formula described in 20 CFR 404.213 for certain workers receiving pensions based on non-covered employment. The Government Pension Offset (GPO) could reduce Social Security spouse or survivor benefits for certain recipients of non-covered government pensions.

The Social Security Fairness Act, enacted on January 5, 2025, repealed WEP and GPO for Social Security benefits payable for January 2024 and later. As of 2026, SSA no longer applies those provisions to current benefit payments. A government pension can still affect other programs, including means-tested SSI eligibility, and workers should obtain a current estimate from SSA rather than relying on benefit calculations prepared before the repeal.

Alternative Disability Programs for Public Workers

Public employees who lack SSDI insured status may have other options. The availability and terms of those options depend on the worker's pension system, employer, insurance coverage, income, and resources.

Public employees facing disabling health conditions should investigate several administrative avenues:

First, ask the state or municipal pension system whether disability-retirement or disability-allowance benefits are available. Programs administered by systems such as CalPERS, STRS plans, or county retirement associations have their own service, filing, and medical requirements. Some focus on whether the worker can perform their usual government job, while others apply broader standards.

Second, if household income and countable resources are limited, the worker may explore Supplemental Security Income (SSI) under Title XVI. SSI does not require Social Security work credits, but it has financial and other eligibility requirements. Pension payments and other income may reduce or eliminate SSI eligibility.

Third, review the Social Security earnings record and available medical evidence to determine whether the condition became disabling while the worker was still insured through earlier covered employment. An SSDI claim may remain possible if the evidence establishes disability on or before the Date Last Insured.

Sibling Site Boundaries and Final Steps

Understanding the division between public pension systems and federal disability insurance is important when planning for disability. Filing procedures, appeals from insured-status determinations, and representation in Social Security proceedings are governed by separate administrative rules.

Public employees should obtain an official Social Security Statement through SSA.gov, verify that their covered earnings are recorded correctly, and request information about disability benefits from their public pension administrator. SSA forms and online services are available without charge through SSA.gov.

Frequently Asked Questions

Why don't all public school teachers earn Social Security work credits?
Under Section 218 of the Social Security Act, state and local governments may extend Social Security coverage to eligible employee groups through agreements with SSA. Some teachers instead work in positions excluded from Social Security coverage, so those wages do not earn Social Security work credits.

Can a government employee qualify for SSDI from an earlier private sector job?
Possibly. The worker generally must establish that disability began while they still met SSA's disability insured-status requirements. For many claimants age 31 or older, 20 CFR 404.130 requires at least 20 quarters of coverage during the 40-quarter period ending with the quarter disability began.

What is Medicare Qualified Government Employment (MQGE)?
MQGE generally refers to state or local government employment covered for Medicare but not for Social Security cash benefits. Medicare taxes paid on that work may help establish eligibility for Medicare based on disability, but the work does not ordinarily earn credits toward monthly SSDI cash benefits.
