SSI and Social Security are separate programs with different rules

Supplemental Security Income (SSI) and Social Security are two different federal programs that sometimes confuse people because they share similar names and are both run by the Social Security Administration. The key difference: Social Security is an insurance program you pay into through payroll taxes during your working years. SSI is a needs-based program for people with low income and limited resources, regardless of work history.

You can receive one, both, or neither — it depends on your age, disability status, income, and how much you have saved. Understanding which program you might receive, or whether you may have access to for both, matters because the payment amounts, rules about working, and what counts as income are completely different between them.

Key Takeaways

  • Social Security requires a work history and payroll tax contributions; SSI does not and is based on financial need instead.
  • Social Security pays based on your earnings record; SSI pays a federal base amount (which varies by state) to people with very low income and resources.
  • SSI has strict resource limits (currently $2,000 for an individual); Social Security has no resource limit.
  • You can receive both programs at the same time if you meet the requirements for each, though your SSI payment may be reduced by your Social Security amount.
  • Work incentives differ: Social Security has a trial work period and earnings test; SSI has a plan to achieve self-support (PASS) and different work rules.

How you build may be able to access for each program

To receive Social Security retirement, survivor, or disability benefits, you must have worked and paid Social Security taxes for a certain number of quarters (three-month periods). The exact number depends on your age and the type of benefit. For retirement, you generally need 40 quarters of work history — about 10 years of employment. For disability, the requirement is lower and depends on your age when you become disabled.

SSI has no work history requirement. You can receive SSI if you are 65 or older, blind, or disabled (including children with disabilities), and your income and resources fall below the program's limits. Your past employment does not matter. What matters is your current financial situation.

Income and resource limits: the biggest practical difference

SSI has strict limits on how much money you can have. As of 2024, you can own no more than $2,000 in countable resources if you are an individual, or $3,000 if you are married and both spouses receive SSI. Resources include savings, checking accounts, stocks, and some vehicles. Your home and one vehicle are usually not counted.

Social Security has no resource limit. You can have a million dollars in the bank and still receive your full Social Security payment. However, Social Security does have an earnings test: if you are under full retirement age and working, your benefits are reduced by $1 for every $2 you earn above a certain amount (the limit changes yearly).

Income rules also differ. SSI counts most income — wages, self-employment, pensions, and other benefits — toward your monthly limit. Social Security counts only earned income (wages and self-employment) in the earnings test; unearned income like pensions or investment returns does not reduce your benefit.

Payment amounts and how they are calculated

Social Security payments are based on your earnings record — how much you earned during your working years. Higher lifetime earnings mean a higher monthly payment. The average Social Security retirement benefit in 2024 is around $1,900 per month, but payments range widely depending on your work history and the age you start receiving benefits.

SSI payments are based on a federal base rate, not your earnings history. The federal base rate for 2024 is $943 per month for an individual (the amount varies slightly by state because some states add their own supplement). This is the same for everyone who receives SSI, regardless of whether you worked or how much you earned.

If you receive both Social Security and SSI, your SSI payment is reduced by the amount of your Social Security benefit. For example, if you receive $600 in Social Security and the SSI base rate is $943, your SSI payment would be $343 per month.

Work incentives and how they affect your benefits

Social Security has an earnings test and a trial work period. If you are under full retirement age, your benefits are reduced if you earn above a certain amount. Once you reach full retirement age, there is no earnings limit — you can work and earn as much as you want without losing benefits. The trial work period allows you to test your ability to work for nine months without losing benefits, even if your earnings are high.

SSI has different work rules. You can work and keep more of your earnings because SSI excludes the first $65 per month of earnings plus half of the remainder. There is also a Plan to Achieve Self-Support (PASS), which lets you set aside income and resources for a specific work goal without losing SSI. A PASS might allow you to save money for education, equipment, or business startup costs while continuing to receive SSI.

How to find out which program you might receive

If you have a work history and are at least 62 years old, you likely may have access to for Social Security retirement. If you are disabled or blind and have limited income and resources, you may may have access to for SSI. If both apply to you, you can receive both — though your SSI payment will be reduced by your Social Security amount.

The Social Security Administration handles applications for both programs. You can start the process online at ssa.gov, by phone at 1-800-772-1213, or in person at your local Social Security office. When you apply, bring documents showing your age, citizenship or immigration status, and income and resource information. If you are applying for disability, you will also need medical records.

The agency will tell you which program you may have access to for based on your specific situation. Processing times vary, but decisions typically take several months.

What happens if you receive one program and circumstances change

If you are receiving Social Security and your income or resources change, your benefit amount usually stays the same — Social Security does not have resource limits and only counts earned income in the earnings test. However, if you start working significantly more, your benefit may be reduced during the earnings test years (before full retirement age).

If you are receiving SSI and your income or resources increase, your SSI payment will be reduced or stopped. SSI is means-tested, meaning the program monitors your financial situation continuously. If you receive a lump sum (inheritance, tax refund, settlement), it counts toward your resource limit immediately. You must report changes in income or resources to SSI within 10 days to avoid overpayments.

Frequently Asked Questions

Can I receive both SSI and Social Security at the same time?

Yes. If you meet the requirements for both programs, you can receive both. Your SSI payment will be reduced by your Social Security amount. For example, if your Social Security is $800 and the SSI base rate is $943, you would receive $143 in SSI plus your $800 in Social Security, totaling $943.

What counts as a resource for SSI purposes?

Resources include savings accounts, checking accounts, stocks, bonds, and most vehicles beyond one. Your primary home and one vehicle do not count. Life insurance policies, retirement accounts (in some cases), and certain items of personal property also do not count. The limit is $2,000 for an individual.

If I work, will I lose my Social Security or SSI?

It depends on which program and how much you earn. Social Security has an earnings test only if you are under full retirement age; once you reach full retirement age, work does not affect your benefit. SSI allows you to work and excludes the first $65 per month of earnings plus half of what you earn above that, so you can work without immediately losing benefits.

How long does it take to get approved for SSI or Social Security?

Social Security retirement applications typically take two to four weeks if you have all documents ready. Disability applications take longer — usually two to three months for an initial decision, though many are denied and require an appeal. SSI applications follow the same timeline as disability applications.

Do I have to be a U.S. citizen to receive SSI or Social Security?

Social Security requires you to have a valid Social Security number and work history, but not necessarily citizenship. SSI requires you to be a U.S. citizen or a may have access to immigrant (certain visa holders, refugees, and asylees). Undocumented immigrants cannot receive SSI, though they may be able to receive Social Security if they have a valid work history.
