Supplemental Security Income and Social Security are separate programs with different rules
Supplemental Security Income (SSI) and Social Security are not the same, even though both are run by the Social Security Administration. The key difference: Social Security is based on your work history and the taxes you paid into the system. SSI is a needs-based program for people with low income and few assets, regardless of work history.
This matters because the two programs have completely different may be able to access rules, payment amounts, and what counts against you. Someone might receive Social Security but not SSI, or SSI but not Social Security, or both at the same time. Understanding which one you might receive — or whether you receive both — changes what you need to know about your benefits.
Key Takeaways
- Social Security is earned through work and payroll taxes; SSI is a needs-based program for people with limited income and resources.
- SSI has strict asset limits (currently $2,000 for individuals) and counts income differently than Social Security does.
- You can receive both Social Security and SSI at the same time if you meet the rules for each program.
- SSI includes Medicaid in most states, while Social Security recipients must sign up for Medicare separately.
How Social Security and SSI differ in who can receive them
To receive Social Security retirement, disability, or survivor benefits, you or a family member must have worked and paid Social Security taxes for a certain number of quarters (three-month periods). The amount you receive is based on your earnings record. If you never worked enough quarters, you cannot receive Social Security benefits on your own record, no matter how much you need the money.
SSI has no work requirement. You can receive it if you are 65 or older, blind, or disabled — and if your income and resources fall below the program's limits. A 30-year-old who has never worked can receive SSI if they are disabled and meet the income and resource rules. A 70-year-old who worked their whole life but has very little income and few assets can also receive SSI.
The two programs can overlap. Someone might receive Social Security retirement benefits because they worked, and also receive SSI because their Social Security payment is small and they have few resources. The Social Security Administration calls this "concurrent receipt."
Resource and income limits that explore only to SSI
SSI has strict limits on how much money and property you can own. As of 2024, you can have no more than $2,000 in countable resources if you are single, or $3,000 if you are married. Resources include cash, bank accounts, stocks, and property — but not your home or one vehicle. If your resources exceed the limit, you lose SSI that month.
Social Security has no resource limit. You can own a house, multiple cars, and have $100,000 in the bank and still receive your full Social Security benefit. The only limit is on how much you can earn from work while receiving benefits before age 67, and that limit applies only to earnings, not to savings or investments.
Income rules also differ. SSI counts most income against your benefit, including wages, unemployment, and help from family members. Social Security counts only earned income (wages) before your full retirement age, and even then only above a certain amount. Unearned income like pensions, investments, or gifts does not reduce Social Security benefits at any age.
What happens to your benefits if you work
If you receive SSI and earn money from work, the program deducts most of it from your benefit. SSI allows you to exclude the first $65 per month of earnings and half of anything above that, but the rest reduces your payment dollar-for-dollar. Working can quickly make you ineligible for SSI if your earnings push your income above the program's limit.
If you receive Social Security before your full retirement age and work, your benefit is reduced by $1 for every $2 you earn above an annual limit. In 2024, that limit is $23,400, but it changes each year. Once you reach your full retirement age, there is no earnings limit — you can work and earn as much as you want without losing benefits.
If you receive both Social Security and SSI, working affects both programs, and the rules stack. This is one reason why people on SSI often work very little or not at all — the benefit reduction can make working not worth the effort.
Healthcare coverage tied to each program
SSI recipients in most states are automatically enrolled in Medicaid, the joint federal-state health insurance program for people with low income. This is a major benefit: Medicaid covers doctor visits, hospital stays, prescriptions, and long-term care services. You do not have to do anything to get it — it comes with SSI.
Social Security recipients do not automatically receive Medicaid. At 65, you become may be able to access for Medicare, the federal health insurance program for older adults. You must sign up for Medicare yourself during your enrollment window, or you may face penalties. Medicare is different from Medicaid: it is based on age or disability, not income, and it has different coverage and costs.
If you receive both Social Security and SSI, you get both Medicaid and Medicare. Medicaid becomes your secondary insurance and can help cover costs that Medicare does not pay.
Payment amounts and how they are set
Social Security payment amounts are based on your lifetime earnings. The higher your average earnings during your working years, the higher your benefit. Payments are adjusted each year for inflation using the Cost of Living Adjustment (COLA).
SSI payments are set by federal law and are the same for everyone in the same situation (single or married). As of 2024, the federal SSI payment for a single person is $943 per month, though some states add money on top of this. SSI payments also increase each year with COLA, but the base amount is much lower than most Social Security benefits.
Because SSI is needs-based, your payment is reduced if you have other income. If you receive both Social Security and SSI, your Social Security payment counts as income, and your SSI payment is reduced by most of it. This is why someone receiving both programs often gets a small SSI payment on top of a larger Social Security payment.
How to find out which program you receive
Your Social Security Statement, which you can view online at ssa.gov, shows whether you are receiving Social Security benefits and how much. If you are receiving SSI, you will receive a separate notice about that benefit.
If you are unsure, you can call the Social Security Administration at 1-800-772-1213 (TTY 1-800-325-0778) and ask a representative which programs you are currently receiving. Have your Social Security number ready. You can also visit your local Social Security office in person.
If you are not currently receiving either program but think you might be able to, the Social Security Administration website has information about how each program works and what the current rules are. You can also speak with a representative to learn more about your specific situation.
Frequently Asked Questions
Can I receive both Social Security and SSI at the same time?
Yes. If your Social Security benefit is small and you have few resources, you may receive both. Your Social Security payment counts as income for SSI purposes, so your SSI payment will be reduced, but you can still receive both benefits in the same month.
If I'm on SSI and I inherit money, what happens to my benefits?
An inheritance counts as a resource. If it pushes your total resources above $2,000 (or $3,000 if married), you will lose SSI that month. Some people spend down the inheritance or put it into certain accounts that do not count as resources, but you should speak with a Social Security representative before accepting an inheritance.
Does SSI ever turn into Social Security when I get older?
No. SSI and Social Security are separate programs with separate rules. If you are receiving SSI at 65, you continue to receive SSI unless your circumstances change. You do not automatically switch to Social Security, though you may become may be able to access for Social Security if you have a work history.
What's the difference between SSI and SSDI?
SSDI (Social Security Disability Insurance) is based on work history, like retirement Social Security. SSI is needs-based and has no work requirement. You can receive SSDI without meeting SSI's resource limits, but you can also receive both if you meet the rules for each.
If I'm on SSI, can I own a house?
Yes. Your primary home does not count toward the $2,000 resource limit for SSI. You can own your home and still receive SSI. However, if you own a second property or a rental property, that counts as a resource and may affect your benefits.
