Social Security and SSI are separate programs with different funding sources and may be able to access rules

Social Security is an insurance program you pay into through payroll taxes during your working years. When you retire, become disabled, or die, Social Security replaces a portion of your lost income based on your work history. SSI (Supplemental Security Income) is a needs-based program funded by general tax revenue, not payroll taxes. You do not need a work history to receive SSI — instead, you must have low income and limited resources, and meet an SSA medical standard for disability, blindness, or age 65 or older.

The two programs operate under completely different rules about how much money you can have, what counts as income, and how much you receive each month. A person can receive both Social Security and SSI at the same time, but the programs are administered separately and have separate application processes.

Key Takeaways

  • Social Security requires a work history and payroll tax contributions; SSI requires low income and resources regardless of work history.
  • Social Security payments are based on your earnings record; SSI payments are based on your current financial need.
  • SSI has strict limits on how much money and property you can own ($2,000 for individuals, $3,000 for couples as of 2024, though these limits vary); Social Security has no resource limits.
  • You can receive both programs at the same time, but you must meet the rules for each one separately.
  • SSI includes Medicaid in most states; Social Security recipients must pay for Medicare or other coverage.

How work history affects which program you can receive

Social Security requires that you or your spouse have worked and paid Social Security taxes for a certain number of quarters (three-month periods). The exact number depends on your age when you apply for disability or retirement. If you have never worked or do not have enough work credits, you cannot receive Social Security retirement or disability benefits, no matter how old you are or how much you need the money.

SSI has no work history requirement. You can receive SSI if you are disabled, blind, or age 65 or older and meet the income and resource limits, even if you have never worked a day in your life. This is why SSI exists — to provide a safety net for people who do not may have access to for Social Security because they lack sufficient work history.

Income and resource limits: SSI is strict, Social Security is not

SSI has strict monthly income limits and resource limits. As of 2024, the federal SSI payment is $943 per month for an individual and $1,415 for a couple, but your actual payment depends on your other income. If you earn money from work, have other benefits, or receive support from family members, your SSI payment is reduced. You can own no more than $2,000 in countable resources as an individual or $3,000 as a couple — this includes cash, bank accounts, and most investments.

Social Security has no resource limit and no limit on how much other income you can have. You can own a house, a car, investments, and savings without affecting your Social Security payment. The only limit is that if you are under full retirement age and still working, your benefit is reduced by $1 for every $2 you earn above a certain threshold — but this reduction stops once you reach full retirement age.

Because SSI limits are so strict, many people who receive SSI must carefully manage their finances and report changes to the Social Security Administration. Receiving a gift, inheritance, or bonus can push you over the resource limit and stop your SSI temporarily or permanently.

How payments are calculated differently

Social Security calculates your benefit based on your lifetime earnings record. The higher your average earnings during your working years, the higher your benefit. Your benefit amount is set when you start receiving it and increases only with cost-of-living adjustments each year. Two people with the same disability can receive very different Social Security amounts depending on how much they earned.

SSI calculates your benefit based on the federal payment amount minus your other income. Everyone who receives only SSI (with no Social Security) receives the same federal payment amount, adjusted for their state. If you have other income, your SSI payment is reduced dollar-for-dollar, with some exceptions for earned income and certain other sources. This means SSI is designed to bring your total monthly income up to a certain floor, not to replace your lost earnings.

Medicaid and Medicare: different health coverage

SSI recipients in most states are automatically enrolled in Medicaid, which covers doctor visits, hospital care, prescription drugs, and other medical services with little or no cost to you. This is a major benefit of SSI — Medicaid is comprehensive and does not depend on your income or resources once you may have access to for SSI.

Social Security recipients do not automatically receive Medicaid. Instead, you become may be able to access for Medicare at age 65, which is a different program that requires monthly premiums and has deductibles and copays. If you are disabled and receiving Social Security Disability Insurance (SSDI), you become may be able to access for Medicare after you have been receiving SSDI for 24 months. If your income is very low, you may also be able to receive Medicaid, but this depends on your state's rules and is not automatic.

What happens if you work while receiving benefits

If you receive SSI and earn money from work, your SSI payment is reduced. The first $65 per month of earnings is not counted, and then SSI is reduced by $1 for every $2 you earn above that. This means you can work part-time and still receive some SSI, but your total income will be capped near the federal payment limit. You must report all work income to the Social Security Administration.

If you receive Social Security Disability Insurance (SSDI) and work, you can earn up to a certain amount ($1,550 per month in 2024, though this changes yearly) during a nine-month trial work period without losing benefits. After the trial work period, your benefits stop if you are earning above the substantial gainful activity level. Social Security retirement benefits are reduced only if you are under full retirement age and earn above a threshold.

Applying for each program separately

You apply for Social Security and SSI through the Social Security Administration, but they are separate applications with separate decisions. You can apply for both at the same time, and the SSA will evaluate you for each program based on its own rules. If you are denied for one program, you may still be approved for the other.

When you apply, you will need to provide proof of your age, citizenship or legal residency, and medical evidence if you are applying based on disability. For Social Security, you will also need your work history. For SSI, you will need to report your income and resources in detail. The application process is the same whether you apply online, by phone, or in person at a local Social Security office.

Frequently Asked Questions

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

Yes. If you meet the requirements for both programs, you can receive both. Your Social Security payment counts as income toward SSI, so your SSI payment will be reduced, but many people receive a combination of both. The SSA will calculate your total benefit when you apply.

What is the difference between SSDI and SSI?

SSDI (Social Security Disability Insurance) is part of the Social Security program and requires a work history. SSI (Supplemental Security Income) is a separate needs-based program with no work requirement. Both are for disabled people, but SSDI is based on your earnings record and SSI is based on financial need.

If I inherit money, will I lose my SSI?

An inheritance counts as a resource and can push you over the $2,000 limit, which would stop your SSI. However, you have a grace period to spend down the money or set it aside in certain approved accounts. You must report the inheritance to the Social Security Administration right away and ask about your options.

Does Social Security have a resource limit like SSI does?

No. Social Security has no limit on how much money, property, or investments you can own. You can receive Social Security and still have a house, savings, investments, or other assets without affecting your benefit amount.

What happens to my SSI if I get married?

Your SSI payment may change because the resource limit increases to $3,000 for a couple, but your spouse's income and resources count toward that limit. If your spouse works or has other income, it will reduce your SSI payment. You must report the marriage to the Social Security Administration.
