Eligibility for an old-age pension in the USA depends on which federal program you’re asking about. Social Security retirement, the program most Americans rely on, requires 40 work credits (about ten years of covered employment) and a minimum age of 62. Supplemental Security Income (SSI) covers people 65 and older who lack enough work history, provided their income and assets fall below strict limits. Veterans who served during wartime and workers with rail-industry careers have their own programs with separate rules. Legal status and residency matter for all of them.
Social Security Retirement: The Main Pathway
Social Security is an insurance program funded by payroll taxes, not a welfare benefit. You earn eligibility by accumulating work credits over your career, and federal law requires 40 credits to qualify for retirement benefits.1Office of the Law Revision Counsel. 42 USC 414 – Insured Status for Purposes of Old-Age and Survivors Insurance Benefits You can earn up to four credits per year. In 2026, each credit requires $1,890 in wages or self-employment income, so $7,560 in a single year maxes out your credits for that year.2Social Security Administration. Quarter of Coverage
Credits don’t expire. If you left the workforce after eight years and never returned, those 32 credits still count; you’d just need eight more to reach 40. Part-time and seasonal work counts too, as long as you hit the earnings threshold. The Social Security Administration tracks your credits automatically through your tax filings.
When You Can Actually Start Collecting
Having 40 credits doesn’t start payments. You also need to reach a qualifying age and file an application.
- Age 62 is the earliest you can claim. Filing at 62 when your full retirement age is 67 permanently reduces your monthly payment to 70 percent of what you’d get by waiting.3Social Security Administration. Benefits Planner – Born in 1960 or Later
- Full retirement age (FRA) is when you receive your full calculated benefit. For anyone born in 1960 or later, FRA is 67. Those born between 1955 and 1959 have an FRA between 66 and 2 months and 66 and 10 months.4Social Security Administration. Retirement Age and Benefit Reduction
- Age 70 is when benefits stop growing. Each year you delay past FRA adds 8 percent through delayed retirement credits, so someone with an FRA of 67 who waits until 70 gets a 24 percent larger check.5Social Security Administration. Delayed Retirement Credits
You can file up to four months before you want payments to start, and you must be at least 61 years and 9 months old at the time of filing.6Social Security Administration. When To Start Benefitsp>
Qualifying Through a Spouse’s or Ex-Spouse’s Record
You don’t necessarily need your own work history. Spouses, ex-spouses, and surviving spouses can qualify based on someone else’s earnings record, which matters for people who spent years outside the paid workforce.
Spousal Benefits
If your spouse has earned enough credits and filed for benefits, you can receive up to 50 percent of their full retirement age benefit amount. You must be at least 62 or caring for a qualifying child, and you need to have been married for at least one year.7Social Security Administration. What You Could Get From Family Benefits Claiming before your own FRA reduces the amount.
Divorced spouses can collect on an ex-spouse’s record if the marriage lasted at least 10 years, the divorce has been final for at least two years, and the person claiming hasn’t remarried. Your ex doesn’t need to know or consent, and their current spouse’s benefits aren’t affected.8Social Security Administration. Who Can Get Family Benefits
Survivor Benefits
A surviving spouse can receive up to 100 percent of the deceased worker’s benefit at their own full retirement age. Reduced survivor benefits are available as early as age 60, or age 50 if the surviving spouse has a disability.9Social Security Administration. What You Could Get From Survivor Benefits A surviving spouse who remarries after age 60 can still collect.10Social Security Administration. Survivors Benefits
Citizenship, Residency, and Payments Overseas
Federal law restricts public benefits to U.S. citizens and certain categories of lawfully present non-citizens.11Office of the Law Revision Counsel. 8 USC 1611 – Aliens Who Are Not Qualified Aliens Ineligible for Federal Public Benefits Lawful permanent residents generally qualify for Social Security if they’ve accumulated enough work credits through covered U.S. employment. Some non-citizens face a five-year waiting period for certain federal benefit programs.
You also need to reside within the 50 states, the District of Columbia, or a qualifying U.S. territory: Puerto Rico, Guam, the U.S. Virgin Islands, the Northern Mariana Islands, or American Samoa.
U.S. citizens who move overseas can generally keep receiving Social Security payments as long as they’re in a country where the Treasury Department allows payments. Non-citizens face tighter rules: if you leave the U.S. for six or more consecutive months without meeting a specific exception, payments stop until you return and stay for at least a full calendar month. Citizens of countries with bilateral social security agreements often qualify for an exception. Payments cannot be sent to Cuba or North Korea regardless of citizenship, and several former Soviet states have heavy restrictions.12Social Security Administration.

SSI at 65 for People Without Enough Work Credits
Not everyone reaches old age with 40 work credits. Supplemental Security Income exists for exactly this group. Funded by general tax revenue rather than payroll taxes, SSI provides monthly payments to people aged 65 or older (as well as those who are blind or disabled at any age) who have very limited income and assets.13Office of the Law Revision Counsel. 42 USC 1382 – Eligibility for Benefits
Resource and Income Limits
The financial bar is low. In 2026, your countable resources cannot exceed $2,000 as an individual or $3,000 as a couple.14Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet Countable resources include bank accounts, cash, stocks, and property beyond your home. Your primary residence, one vehicle, personal belongings, and household goods are excluded. If your resources climb above the limit, benefits are suspended until you spend down.
Income works differently. Most outside income reduces your SSI payment, though the program allows small exclusions: the first $20 per month of unearned income and the first $65 per month of earned income are disregarded, and half of any remaining earned income is also excluded.15Social Security Administration. Income Exclusions for SSI Program If you’re married and your spouse doesn’t qualify for SSI, a portion of their income is “deemed” to you and counted against the limit.
Payment Amounts
The maximum federal SSI payment in 2026 is $994 per month for an individual and $1,491 per month for a couple.14Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet Most states add a supplement on top of the federal amount, though the supplement varies widely, and a handful of states provide no supplement at all. Any countable income reduces the payment from these maximums.
Veterans Pension
The Veterans Pension pays a tax-free monthly benefit to wartime veterans who are 65 or older or permanently disabled, and who have limited income and net worth. You must have served at least 90 days of active duty, with at least one day during a recognized wartime period.16Office of the Law Revision Counsel. 38 USC 1521 – Veterans of a Period of War For 2026, the net worth limit is $163,699, which includes most assets except your home and personal property.17U.S. Department of Veterans Affairs. Current Pension Rates for Veterans
The VA also applies a three-year look-back when you file. If you transferred assets for less than fair market value during that window to get below the net worth limit, you could face a penalty period of up to five years during which you’re ineligible.17U.S. Department of Veterans Affairs. Current Pension Rates for Veterans
Railroad Retirement
Workers in the rail industry are covered by the Railroad Retirement Board instead of standard Social Security. Benefits are calculated under a two-tier structure that generally pays more than Social Security alone. Tier I mirrors the Social Security formula using combined railroad and Social Security earnings; Tier II acts like an industry pension based on railroad earnings and years of service.18U.S. Railroad Retirement Board. Frequently Asked Questions
You need at least 10 years of railroad service (or 5 years if all of it was after 1995) to qualify for a railroad retirement annuity. Workers with 30 years of service can retire as early as age 60 with no reduction. Those with fewer years face the same age-62 early retirement rules as Social Security, with reduced benefits.19United States Code. 45 USC 231 – Definitions Qualifying military active duty can be credited toward railroad service requirements under certain conditions.
How to Apply
Applications for Social Security retirement benefits can be submitted online at ssa.gov, by phone, or at a local Social Security office. The online application is typically the fastest route. You’ll want the following on hand:
- Social Security card or a record of your number
- Birth certificate (original or agency-certified copy) or other proof of age
- Proof of citizenship or lawful status if you were not born in the U.S.
- Military discharge papers if you served before 1968
- Most recent W-2 or self-employment tax return
The SSA needs original or certified copies of identity and age documents; photocopies and notarized copies won’t be accepted. Don’t delay your application over a missing document, though. The SSA advises filing on time and submitting missing paperwork afterward, because a late application can mean forfeited benefits that cannot be recovered retroactively.20Social Security Administration.
