SSI Program

The SSI Program stands for Supplemental Security Income and is administered by the Social Security Administration [i]. It pays cash to low-income Americans in two categories: those over 65 and those under 65 who are disabled or blind. The definition of disabled includes both physical and mental disabilities. Participants in the Program receive cash every month.  

Graph of participation in the SSI Program from 2000 through 2023.

In 2023, the maximum benefits for an individual living alone and with no Countable Income equaled $914 monthly ($10,968 annually). For a couple, the maximum was $1,371 per month ($16,452 annually). Countable Income lowers the benefits generally fifty cents per dollar of income from wages or self-employment and dollar for dollar from other benefit programs such as social security.  

Individuals with wages or self-employment income less than $22,956 annually and couples at $33,924 per year are eligible for the SSI Program [ii]. In addition to disability, age, and income eligibility standards, applicants are limited to a “Resource” value of $2,000 for individuals or $3,000 for a couple. Resource value includes cash savings and investments but excludes a home and car.  

In December 2022, the SSI Program had 7.6 million [iii] participants; 84% qualified based on a disability, 15% based on age, and 1% because they were blind. The Program spent $62.0 billion in fiscal year 2023 and $63.3 billion in fiscal year 2022 [iv].    

SSI Participants Over the Years

The chart above shows the number of SSI Program participants since 2000 [iii].  

Participation in the Program by elderly Americans is a small portion of SSI as Social Security continues to protect most retirees in the country.   Retired individuals in the SSI Program do not get a sizeable old-age pension. Neither they nor a spouse worked enough years to generate a Social Security pension larger than the SSI benefit.  Participation by blind individuals has remained consistent between 64,000 and 73,000 over the years. Participation by disabled individuals has increased by 21% since 2000 compared to the population growth of 18% for the same period.   

Entire Welfare System

SSI is one of thirteen welfare programs. The Welfare Programs Page explains how it fits into the entire system.

SSI Improper Payments and Fraud 

The Office of Management and Budget estimates a 9.2% Improper Payment rate related to the SSI Program, totaling $5.7 billion.  See more information on the Welfare Fraud Page.   

History of SSI

The following history of SSI was adapted from Wikipedia, SSI [v], and the Annual Statistical Supplement To The Social Security Bulletin, History of Provisions [i].

President Richard Nixon signed the Social Security Amendments of 1972, which created the SSI Program. At that time, each state had similar programs under the Aid to the Blind, Aid to the Permanently and Totally Disabled, and Aid to the Elderly. The Nixon Administration thought these programs should be federalized and run by the Social Security Administration. Thus, SSI was created to eliminate the differences between the states, including different disability standards and income and resource requirements.  The benefit payment made in cash to qualified participants was $130, and $195 for an individual and couple.  They have been increased by inflation each year since and are the basis for today’s cash benefit.  

The definitions of blind and elderly still generally exist today, but the definition of disabled has changed over the years. The act described disabled as “any person unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment expected to result in death or that has lasted or can be expected to last for a continuous period of at least 12 months.”

In 1994, the definition of disabled was amended for cases where drug addiction or alcoholism (DA&A) is a contributing factor material to the finding of disability.  Such cases were limited to a total of 36 benefit months, and treatment requirements were implemented.  This was changed in 1996, whereby an individual is not considered disabled if DA&A is a contributing factor material to a finding of disability. Payments to disabled SSI recipients who have a DA&A condition (whereby DA&A was not a material contributing factor toward disability) and are incapable of managing their benefits must be made to a representative payee.  Preference must be given to community-based nonprofit social service agencies and federal, state, or local government agencies in representative payee selection. When serving as payees for individuals receiving payments based on DA&A, these agencies may retain the lesser of 10 percent of the monthly benefit or $51 (indexed to the Consumer Price Index  – CPI) as compensation for their services. 

While the act has been relatively stable over the years in its approach and benefit payments, numerous amendments have been made related to legal aliens, how they are paid, and the interface with Medicaid and its benefits.

SSI Expenditures Over The Years

The chart below shows SSI Program expenditures adjusted over the years for inflation’s impacts, stated in 2022 dollars [vi].  The increase or decrease in expense from year to year is related to growth or decline in recipients as the benefit level has remained constant once adjusted for inflation.
