Social Security is a lifeline for more than 69 million Americans each month, according to the Social Security Administration (SSA). It’s designed to supplement your income when you retire or become disabled, but not everyone qualifies. Although most working Americans assume they’ll qualify for benefits sometime in the future, there are several groups of individuals who are surprised to learn they don’t qualify.
As 10,000 Baby Boomers turn 65 each day and retirement is on many minds, it’s important to understand where the coverage gaps are. Suze Orman says, “You cannot build a solid retirement plan on assumptions—Social Security is only guaranteed if you’ve met all the rules.” Know them, or get left behind.”

Some Noncitizens
Not all immigrants qualify for Social Security benefits, even after working and residing in the U.S. for decades. To qualify, a noncitizen must have legal permission to work and earn at least 40 work credits, the equivalent of 10 years of covered work. The Migration Policy Institute puts the number of unauthorized immigrants residing in the U.S. at over 1.2 million, most of whom will never qualify due to their unauthorized status.
Even legal permanent residents will struggle to qualify if they immigrated to the U.S. later in life or worked under-the-table jobs. Immigration policies also fluctuate, with emerging legislation like the Dignity Act of 2024 potentially reshaping future qualification rules.
Short-Term Workers
Workers who don’t work long enough to earn the necessary 40 work credits won’t qualify for retirement benefits. One credit in 2025 will take earnings of $1,810, and you can only get a maximum of four credits in a year. That means people who have on-and-off or part-time employment will take longer to qualify or never qualify at all.
A Pew Research study found that 16% of millennial and Gen Z workers are engaging in gig work without any steady earnings or tax contributions, placing them at high risk of future ineligibility. More freelancing and remote contract work have accelerated this gap, particularly for women who exit the workforce for caregiving.
Retirement planner Jane Bryant Quinn advises, “Track your earnings each year. One missing year could erase decades of planning if it puts you under the credit threshold.”
Certain State and Local Government Employees
Some state and local government employees are not covered under Social Security if their job offers an alternative pension plan. The SSA estimates that over 5 million public sector workers have no Social Security coverage whatsoever. This exception can be confusing, especially in the case of workers switching between the public and private sectors.
Those covered by it may also face reduced benefits due to the Windfall Elimination Provision (WEP), which lowers Social Security benefits for those with pensions from non-covered employment. In 2024, the Public Servants Protection and Fairness Act was introduced to address the impact of WEP, but it remains in Congress.
Railroad Workers
Railroad workers fall under the Railroad Retirement Board (RRB), a unique federal system that replaces Social Security for qualified workers. This system has provided benefits sometimes bigger than Social Security since 1935, but it isn’t the same thing.
Over 500,000 retirees receive RRB benefits today, but younger workers are less likely to know the distinction. Financial analyst Teresa Ghilarducci advises, “Railroad workers should keep an eye on both systems if they switch careers—coordination errors can derail your retirement.”
Some Divorced Spouses
Divorced spouses are eligible for spousal Social Security benefits, but the qualifications are strict. You would need to have been married for 10 consecutive years and be currently unmarried at the time of application. Spousal benefits can amount to 50% of your ex-spouse’s benefit, which is a considerable sum for low-income earners, according to the SSA.
However, many applicants are denied for failing to meet the marriage duration requirement or remarrying too quickly. AARP suggests that divorced spouses get their earnings records early to ascertain eligibility before applying.
Certain Self-Employed Workers
Self-employed individuals must pay both the employer and employee portions of Social Security taxes, totaling 15.3%. Failure to report income or file taxes can result in lost credits, disqualifying individuals from retirement, disability, or survivor benefits. Without tax reporting, the SSA cannot apply credits, even if the work was consistent and income-earning.
The majority of gig workers mistakenly believe platform payments qualify automatically, but Schedule SE reporting is required. With nearly 36% of the U.S. workforce participating in the gig economy, the issue is rapidly growing. Tax attorney Jean Chatzky warns, “If you’re not paying self-employment tax, you’re trading short-term savings for long-term risk.”
Members of Religious Groups
Members of some religious groups, like the Amish or Old Order Mennonites, can apply for exemption from Social Security taxes on religious grounds. These exemptions are not typical and require that the group have a system of mutual aid to care for elderly or disabled members.
This exemption, if granted, is final and irreversible, even if the individual later has a change of heart. The IRS and SSA require signed affidavits to verify religious devotion and provisions for other care. This decision entails waiving not only retirement benefits but also Medicare, disability, and survivor benefits.
The SSA advises that religious members consult with legal counsel before applying because the determination impacts long-term health and fiscal security.
Expatriates in Certain Countries
United States citizens can receive Social Security benefits abroad, but payments are not made in some countries due to sanctions or diplomatic policy. North Korea, Cuba, and parts of Belarus are on this excluded list. As of 2023, the SSA was paying over 700,000 beneficiaries living abroad, but an estimated 8,500 had payments withheld by location.
The Treasury Department prohibits fund transfers to these countries to prevent money laundering and financing of hostile regimes.
Children of Deceased Workers Without Legal Adoption
Kids may be eligible for survivor benefits, but only if the SSA deems them legal dependents of the deceased worker. If a kid wasn’t legally adopted or is step-related without legally adopting, they could be excluded from benefits. This typically affects kinship care situations in which kids are being brought up by grandparents or extended family members informally.
Child welfare organizations warn that informal custody arrangements put many minors at risk if a caregiver dies. Legal experts now recommend guardianship documents or adoption to ensure Social Security access. As family law attorney Elura Nanos explains, “Without a legal paper trail, the SSA won’t budge—even if the child lived with and was dependent on the worker for years.”
Workers in Jobs Not Covered by Social Security
Some jobs, particularly those working for international nonprofits, do not contribute to Social Security. These employees may mistakenly believe they’re paying in when they’re not. The SSA places over 1.7 million American workers in jobs not covered under Social Security, typically due to special tax arrangements or organizational exemptions.
An Inspector General report in 2023 noted the very poor transparency of employment contracts, lacking Social Security tax deductions. Workers in these sectors must often rely on private retirement savings or foreign pension systems that may not match SSA benefits.
The Government Accountability Office now urges stricter employer disclosure on tax withholding practices. Retirement strategist Chris Hogan warns, “Check your paycheck—not all jobs build Social Security credits, and it’s your responsibility to know.”
High-Earning Workers Impacted by the WEP and GPO
The Windfall Elimination Provision (WEP) and Government Pension Offset (GPO) reduce Social Security benefits for employees who have pensions from non-covered employment. While these provisions were designed to prevent “double dipping,” many of those affected feel blindsided.
WEP can reduce benefits by up to $557 a month, but it’s not always a guaranteed cut, and the actual reduction varies based on individual circumstances. Bills like the Social Security Fairness Act propose to repeal these provisions, but the movement has been slow.
People Who File Late Past a Certain Age Without Applying
While delaying Social Security increases monthly payments, failing to file by age 70 forfeits potential payments. The SSA does not retroactively pay benefits before filing, so delaying beyond age 70 results in permanent loss. The Center for Retirement Research at Boston College studied and found that approximately 9% of seniors lost benefits because of misunderstandings about deferral rules.
The SSA recently launched outreach efforts to alert individuals nearing age 70 who haven’t applied, but gaps remain. With the average retirement benefit reaching $1,907 a month in 2025, each lost year can exceed $22,800. Retirement author and expert Emily Guy Birken advises, “Never wait past 70—there’s no benefit and every dollar forfeited is forever.”
Individuals Without a Valid Social Security Number (SSN)
A valid SSN is required to report earnings and determine eligibility for benefits. Workers who use fictitious, stolen, or temporary numbers can earn income, but the SSA cannot credit the wages. The 2024 SSA Wage Reporting Report identified over 6 million earnings reports with unmatched SSNs, uncrediting those earnings.
Undocumented workers and workers utilizing Individual Taxpayer Identification Numbers (ITINs) are disproportionately affected by this issue and might believe they’re contributing to Social Security. Though their taxes may go toward funding the program, they won’t see the benefit without a correct SSN paired with consistent, verified employment.
In a 2023 interview, SSA Commissioner Martin O’Malley stressed the importance of correcting SSN mismatches to avoid long-term eligibility issues.
People Who Take Early Retirement and Die Young
Claiming Social Security early—starting at age 62—reduces monthly benefits permanently. While early access helps most retirees, those who die shortly after claiming may not receive the value they contributed over a lifetime. In 2023, nearly 34% of early retirees died within 10 years of claiming, often before recouping their full contributions.
Survivor benefits may apply, but only for eligible dependents. Those without a surviving spouse or minor children see their benefits vanish with their passing. Economist Teresa Ghilarducci notes, “Early claiming is a gamble. If you’re single or have no dependents, your benefits die with you.”
Persons With Pending Federal Warrants or Incarcerated
SSA suspends benefits for incarceration exceeding 30 consecutive days after conviction. Benefits end for retirement, disability, and survivor programs and do not resume until official release. Additionally, those with outstanding felony warrants may be barred from receiving benefits under the 1996 welfare reform laws.
This includes those unaware of unresolved legal issues from decades prior. Efforts are underway to reform these restrictions, especially for nonviolent offenses, but current laws remain strict. Criminal justice reform advocate Marc Mauer says, “We’re denying seniors benefits they paid for—long after they’ve served time or proven rehabilitation.”
Key Takeaways
Social Security benefits are not guaranteed for everyone, and several groups may be surprised to find themselves ineligible. Noncitizens without proper legal status or enough work credits, short-term or part-time workers, and some state and local government employees with alternative pensions may not qualify.
Self-employed individuals and gig workers often lose out if they fail to report income and pay self-employment taxes. Divorced spouses must meet strict rules—such as being married for at least 10 years—to receive benefits, while members of certain religious groups who opt out for faith-based reasons give up all Social Security coverage permanently.
Other groups affected include U.S. citizens living in sanctioned countries, such as Cuba or North Korea, where payments are restricted. Children not legally adopted, workers in jobs not covered by Social Security (like those in foreign embassies or tribal organizations), and individuals using invalid Social Security numbers can also miss out.
Additionally, government employees impacted by the Windfall Elimination Provision (WEP) or Government Pension Offset (GPO) may receive reduced benefits. People who delay filing past age 70 lose benefits permanently, and those who retire early but die young may never fully benefit from what they paid in.
Finally, individuals who are incarcerated or have unresolved felony warrants face suspended benefits. Knowing these rules is essential for avoiding costly surprises in retirement planning.
