Social Security is responsible for two major programs that provide benefits based on disability: 

* Social Security Disability Insurance (SSDI), which is based on prior work under Social Security,

* Supplemental Security Income (SSI). 

Social Security Disability Insurance (SSDI) is financed with Social Security taxes paid by workers, employers, and self-employed persons.  To be eligible for a Social Security benefit, the worker must earn sufficient credits based on taxable work to be "insured" for Social Security purposes. 

Disability benefits are payable to blind or disabled workers, widow(er)s, or adults disabled since childhood, who are otherwise eligible.  The amount of the monthly disability benefit is based on the Social Security earnings record of the insured worker.

What is the difference between Social Security disability and SSI?

This is confusing to a lot of people because both programs are administered by the Social Security Administration. Social Security Disability Insurance (SSDI) is a program that workers, employers and the self-employed pay for with their Social Security taxes. You qualify for these benefits based on your work history and the amount of your benefit is based on your earnings.

Supplemental Security Income (SSI) is a program financed through general tax revenues -- not through Social Security trust funds. SSI disability benefits are paid to people who have a disability and who don't own much or have a lot of income.Investments & retirement savings
