What Is Supplemental Security Income (SSI)?

Supplemental Security Income (SSI) is a federal program that helps people with disabilities and very low incomes pay for food, clothing and shelter. SSI is often confused with Social Security Disability Insurance (SSDI). One of the main differences between the two programs is that SSDI is available to people with disabilities no matter how much money they earn or have, while SSI places very strict limits on a recipient’s income and assets. However, in most states, an SSI beneficiary who receives even $1 from the program also qualifies for Medicaid health coverage, which can be far more valuable than SSI’s benefit itself.

Because SSI’s income and resource limits are so restrictive, it pays to know the basics about the program before deciding whether it is right for your family member or you.


This first requirement is often the hardest for SSI applicants to meet, in large part because the federal government’s definition of “disabled” is so narrow. In essence, adult SSI applicants who are seeking benefits based on a disability must show that they are almost completely unable to work at any job whatsoever. The applicant must have a physical or mental impairment that makes it impossible for him to engage in any “substantial gainful activity,” and this impairment must be expected to last for longer than one year or to result in death. If an applicant is able to engage in substantial gainful activity, then he will typically not be eligible for SSI. A child applicant must have a physical or mental impairment that results in marked and severe functional limitations and can be expected to last for longer than one year or result in death.


Once an SSI applicant has shown that she is disabled, she must also prove that she has less than $2,000 to her name. If the applicant can use or liquidate an asset to pay for food or shelter, the asset will probably count as a “resource” against this limit. A resource would include any funds held in the applicant’s bank accounts, retirement accounts, or in cash. If the applicant has set up a trust that does not meet specific requirements, the trust funds are also counted against the $2,000 limit. The applicant’s own home will not be considered an available resource, and her car is also exempt. The $2,000 resource limit does not disappear once a person qualifies for SSI. If an SSI beneficiary ends a month with more than $2,000 in her name, she will lose her benefits in the following month.

SSI recipients get only a modest monthly benefit, and this sum is reduced by any income they may have. In 2021, the maximum federal SSI benefit is $794 a month for an individual, although many states add a small supplement to this. In addition, SSI benefits are reduced by $1 for each dollar of unearned income a beneficiary receives (such as interest or dividends), and by $0.50 for each dollar of earned income (such as wages). SSI benefits are also reduced if an adult beneficiary lives in someone else’s home without paying rent, or if he receives free meals. Finally, the income of the people living with the beneficiary can count against the beneficiary. If the beneficiary’s combined income reduces his SSI benefit to zero, he loses SSI, along with any Medicaid benefits that may come with it.


Although SSI’s income and asset rules are highly restrictive, several types of trusts, called “Special Needs” or “Supplemental Needs” trusts, can protect an SSI beneficiary’s assets while allowing her to maintain SSI eligibility. Relatives and friends of the SSI recipient can also set up a trust for the recipient and fund it with their own money. If properly structured, these trusts also will allow an SSI recipient to continue receiving benefits. Unfortunately, a poorly drafted special needs trust can destroy any hopes an applicant has of ever qualifying for SSI.
