SSI and Social Security are separate programs with different rules

Supplemental Security Income (SSI) and Social Security are not the same thing. They are two distinct federal programs run by the Social Security Administration, but they have different funding sources, different income limits, and different rules about who can receive them.

Social Security is an insurance program funded by payroll taxes. You earn credits by working and paying into the system, and you receive benefits based on your work history. SSI is a needs-based program funded by general tax revenue. You do not need a work history to receive it — instead, you must have very low income and resources, and meet one of three conditions: you are 65 or older, blind, or disabled.

The confusion is understandable because the Social Security Administration runs both programs, and some people receive both at the same time. But the way you get them, how much you receive, and what counts against you are fundamentally different.

Key Takeaways

  • Social Security is based on your work history and payroll tax contributions; SSI is based on financial need and age, blindness, or disability status.
  • Social Security has no income or resource limits; SSI has strict limits ($2,000 in resources for individuals, $3,000 for couples, though these figures can change).
  • Social Security benefits are the same nationwide; SSI payments vary by state because states can add money to the federal base amount.
  • You can receive both Social Security and SSI at the same time if your Social Security payment is low enough to fall within SSI income limits.

How Social Security and SSI funding works differently

Social Security comes from a dedicated payroll tax — 6.2 percent from employees and 6.2 percent from employers, plus self-employment tax if you work for yourself. This money goes into a trust fund, and your benefits are calculated based on how much you paid in over your working years. The more you earned and the longer you worked, the higher your benefit.

SSI comes from the general U.S. Treasury, not from payroll taxes. The federal government sets a base payment amount each year (in 2024, the federal base is $943 per month for an individual, though this changes annually). States can choose to add their own money on top of the federal amount. Because of this, SSI payments range from the federal minimum to higher amounts depending on which state you live in.

This difference matters because it determines who can get each benefit. You cannot receive Social Security unless you have worked enough to earn 40 credits — roughly 10 years of work history. You can receive SSI without ever having worked, as long as you meet the other requirements.

Income and resource limits: the biggest practical difference

Social Security has no income limit and no resource limit. If you receive a Social Security benefit, you can earn as much money as you want from other sources, own as much property as you want, and have as much in savings as you want. Your benefit amount does not change based on your other income or assets.

SSI has strict limits on both. To receive SSI, your countable resources cannot exceed $2,000 for an individual or $3,000 for a couple (these limits are set by federal law and do not change annually, though Congress can raise them). Your countable income cannot exceed the SSI payment amount for your state. If you earn money from work, SSI counts most of it against your benefit — though there are some exclusions for the first $65 per month of earned income plus half of anything above that.

This means if you receive SSI and you get a job, your SSI payment will likely go down or stop. If you receive Social Security and you get a job, your Social Security payment stays the same. This is a critical difference if you are thinking about working while receiving benefits.

Work incentives and how they apply to each program

Social Security has a Substantial Gainful Activity (SGA) limit if you are receiving disability benefits. In 2024, SGA is $1,550 per month (or $2,590 for blind beneficiaries). If you earn more than this amount, Social Security may determine that you are no longer disabled and stop your benefits. However, there are work incentive programs like Impairment Related Work Expenses (IRWE) and Plans to Achieve Self-Support (PASS) that can help you keep working without losing benefits.

SSI also has work incentives, but they work differently because SSI is means-tested. The first $65 of monthly earned income is excluded, and then half of the remaining income is excluded. This means you can earn some money and still receive a reduced SSI payment. SSI also has a Plan to Achieve Self-Support (PASS) program that lets you set aside income and resources for a work goal without it counting against your SSI limit.

If you receive both Social Security and SSI, you need to understand how work affects each one separately, because the rules are not the same.

What happens if you receive both Social Security and SSI

You can receive both programs at the same time. This typically happens when your Social Security benefit is very low — for example, if you worked part-time for many years, or if you are a widow or widower receiving a reduced benefit based on your spouse's work history.

When you receive both, Social Security pays first. SSI then looks at your total countable income (including your Social Security payment) and pays you an amount that brings you up to the SSI payment level for your state. This is called deemed income — SSI counts your Social Security as income and reduces your SSI payment accordingly.

For example, if the federal SSI payment is $943 per month and you receive a Social Security benefit of $600 per month, SSI would pay you $343 per month (assuming no other income and you live in a state that does not add to the federal amount). The two payments together equal the SSI limit.

State variations in SSI payments

Social Security benefits are identical nationwide. A person in California receives the same amount as a person in Maine if they have the same work history and age.

SSI payments vary significantly by state. Some states add substantial amounts to the federal base, while others add very little or nothing. For example, California, New York, and Massachusetts have state supplements that can add $100 to $200 or more per month to the federal SSI amount. Other states provide no state supplement at all.

If you move from one state to another while receiving SSI, your payment amount will change. This is important to know if you are planning to relocate. You should contact your local Social Security office before moving to find out what your SSI payment will be in the new state.

How to tell which program you are receiving

Your Social Security statement or payment notice will tell you which program you are on. Social Security benefits are labeled as retirement, survivor, or disability benefits. SSI is labeled as Supplemental Security Income.

If you are unsure, you can call the Social Security Administration at 1-800-772-1213 (TTY 1-800-325-0778) and ask. You can also create an account at ssa.gov and view your benefit information online. Your local Social Security office can also provide a written statement showing which program you receive and how much your monthly payment is.

Frequently Asked Questions

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

Yes. This happens when your Social Security benefit is low enough that you still fall within SSI income limits. Social Security pays first, and SSI pays you an additional amount to bring your total up to the SSI payment level for your state. You must meet SSI's other requirements: you must be 65 or older, blind, or disabled, and your countable resources cannot exceed $2,000.

If I work, which program will my earnings affect?

Both, if you receive both. Earnings count as income for both Social Security disability benefits (if you earn above the SGA limit) and SSI (where most earnings reduce your payment). If you receive only Social Security retirement benefits, work does not affect your payment. If you receive only SSI, work will reduce your SSI payment but not affect any other Social Security you might be may have access to to.

Why is my SSI payment different from my friend's if we both live on the same income?

SSI payments vary by state. Your friend may live in a state that adds a supplement to the federal SSI amount, or you may. Even if you both receive the federal base amount, your friend might have different countable income or resources, which would change their payment. Call Social Security to confirm what your state's SSI payment amount is.

Does Social Security count my SSI payment as income?

No. Social Security and SSI are separate programs, and Social Security does not count SSI payments as income. However, SSI counts Social Security as income and reduces your SSI payment by the amount you receive in Social Security.

What if I inherit money while receiving SSI?

Inherited money counts as a resource for SSI purposes. If your countable resources exceed $2,000, you will lose SSI until your resources drop back below the limit. Some inherited items may be excluded — for example, a home you live in does not count. You should contact your local Social Security office immediately if you inherit money or property to find out how it affects your SSI.
