SSI and Social Security are not the same, though the names sound similar and both are federal programs

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 earnings record.

SSI (Supplemental Security Income) is a needs-based program for people with low income and few assets, regardless of work history. You do not need to have worked to receive SSI. The program serves three groups: people aged 65 and older, people who are blind, and people with disabilities.

The confusion happens because both programs are run by the Social Security Administration, both use the word "security," and both can help people who cannot work. But they operate on completely different rules, pay different amounts, and serve different populations.

Key Takeaways

  • Social Security requires a work history and payroll tax contributions; SSI does not and is based on financial need instead.
  • Social Security payments are typically higher and do not have asset limits; SSI has strict limits on how much money and property you can own.
  • You can receive both Social Security and SSI at the same time, though SSI payments will be reduced by the amount you get from Social Security.
  • Social Security is available to workers, retirees, disabled workers, and surviving family members; SSI is only for people with low income and few resources.
  • The application process, waiting periods, and medical review standards differ between the two programs.

How Social Security and SSI differ in who can receive them

Social Security is tied to your work record. To receive retirement benefits, you generally need 40 work credits (roughly 10 years of work). To receive disability benefits through Social Security (called SSDI), you need fewer credits depending on your age, but you still need some work history. Surviving spouses and children of a deceased worker can also receive Social Security benefits based on that worker's record.

SSI has no work requirement at all. Instead, it looks at your current financial situation. To receive SSI, you must have limited income (the monthly limit varies by state but is typically around $900 to $1,000 for an individual) and limited resources (usually $2,000 or less in countable assets for an individual, $3,000 for a couple). Your home and one vehicle are not counted as resources.

This means a person who never worked can receive SSI if they are disabled, blind, or over 65 and have low income. A person who worked for 30 years but has substantial savings may not may have access to for SSI, even if they are disabled.

Payment amounts and how they are calculated

Social Security payments are based on your lifetime earnings. The higher your average earnings during your working years, the higher your benefit. The Social Security Administration calculates this using a formula that accounts for inflation and your 35 highest-earning years. Payments typically range from around $1,000 to $3,800 per month, though amounts vary widely.

SSI payments are set by federal law and do not vary based on work history. The federal benefit rate for 2024 is $943 per month for an individual (rates change each year). Some states add money on top of the federal amount, so your total SSI payment may be higher depending on where you live. Unlike Social Security, your SSI payment does not increase based on your past earnings.

If you receive both Social Security and SSI, your SSI payment is reduced dollar-for-dollar by the amount you receive from Social Security. For example, if you get $600 in Social Security and the federal SSI rate is $943, you would receive $343 in SSI.

Asset and income limits that apply only to SSI

Social Security has no asset limit. You can own a house, multiple vehicles, investment accounts, and savings without affecting your Social Security payments. Your income from other sources also does not reduce your Social Security benefit (though if you work before full retirement age, your benefit may be temporarily reduced).

SSI has strict limits. You can own no more than $2,000 in countable resources as an individual (or $3,000 as a couple). Countable resources include bank accounts, stocks, bonds, and cash. Your home does not count, and one vehicle does not count, but a second vehicle, vacation property, or a boat would count toward your limit.

SSI also has income limits. In 2024, the limit is roughly $1,000 per month for an individual, though some income is not counted (such as the first $65 of earned income per month, plus half of remaining earnings). If your income exceeds the limit, you lose SSI, even if you are disabled.

Medical review and how disability is determined

Both programs require medical evidence if you are applying based on disability, but the standards and review processes differ. Social Security Disability Insurance (SSDI) and SSI both use the same medical criteria to determine if you have a severe impairment that prevents substantial work. However, the frequency of medical reviews and the process for continuing benefits can differ.

For SSI, the Social Security Administration conducts continuing disability reviews (CDRs) to make sure you still meet the medical criteria. The timing depends on your condition: people with conditions expected to improve are reviewed more often, while people with permanent conditions are reviewed less frequently. If your income or resources change, you must report it, or you may lose benefits.

For Social Security Disability, reviews also happen, but the schedule is typically less frequent than for SSI. Once you reach full retirement age, your disability benefit automatically converts to a retirement benefit, and medical reviews stop.

How to apply for each program

You apply for Social Security retirement or disability benefits through the Social Security Administration. You can apply online at ssa.gov, by phone at 1-800-772-1213, or in person at your local Social Security office. The application process typically takes several weeks to several months. If you are denied, you can appeal.

SSI applications also go through the Social Security Administration using the same channels. However, SSI applications often take longer because the agency must verify your income and resources in detail. You will need to provide documents showing your bank statements, rent or mortgage payments, and any other income sources.

You can apply for both programs at the same time if you think you might may have access to for both. Some people receive Social Security based on their own work record and also receive a small SSI payment to bring their total income above the poverty line.

What happens to your benefits if your situation changes

If you receive Social Security and your income or resources change, your benefit usually does not change. Social Security is not affected by how much money you have in the bank or whether you work part-time (though earnings before full retirement age can reduce your benefit temporarily).

If you receive SSI and your situation changes, you must report it to Social Security. If your income increases, your SSI payment decreases or stops. If you receive an inheritance or gift, it counts toward your resource limit. If you move to a different state, your SSI payment may change because some states add money to the federal rate. Failure to report changes can result in overpayments that you may have to repay.

Both programs have work incentives that allow you to work and still receive some benefits, but the rules are different. If you are considering working while receiving either benefit, contact Social Security before you start to understand how your earnings will affect your payments.

Frequently Asked Questions

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

Yes. If your Social Security payment is low, you may also receive SSI. Your SSI payment will be reduced by the amount you receive from Social Security. For example, if Social Security pays you $600 and the federal SSI rate is $943, you would get $343 in SSI, for a total of $943.

I worked for 20 years but stopped. Can I get SSI?

Yes, if you meet the other requirements. SSI does not require any work history. You need to be 65 or older, blind, or disabled, and you must have low income and few resources. Your past work does not help or hurt your SSI case.

What if I inherit money while receiving SSI?

An inheritance counts as a resource and will affect your SSI. If the inheritance pushes your total resources above $2,000, you will lose SSI until you spend the money down. Some inheritances may be excluded under certain rules, so contact Social Security before accepting an inheritance.

Does working part-time reduce my Social Security benefit?

If you have reached full retirement age, no. If you have not reached full retirement age and you work, your Social Security benefit is reduced by $1 for every $2 you earn above an annual limit (the limit changes yearly). Once you reach full retirement age, you can earn any amount without reduction.

How long does it take to get approved for SSI?

SSI applications typically take two to four months, though some take longer if Social Security needs more medical evidence or documentation of your income and resources. If you are denied, you can appeal, and the appeal process can take several more months.
