Understanding Social Security Disability Benefits

Disability is something most people don’t like to think about, but the chances that you’ll become disabled are greater than you realize. Studies show that a 20-year-old worker has a 1-in-4 chance of becoming disabled before reaching full retirement age.

Social Security pays disability benefits through two programs:

  1. The Social Security Disability Insurance (SSDI) program.
  2. The Supplemental Security Income (SSI) program.

Social Security Disability Insurance (SSDI)

Social Security pays benefits to people who can’t work because they have a medical condition that’s expected to last at least one year or result in death. Federal law requires this very strict definition of disability. In addition to meeting our definition of disability, individuals must have worked long enough — and recently enough — under Social Security to qualify for SSDI benefits. While some programs give money to people with partial disability or short-term disability, Social Security does not.

SSDI is funded through payroll taxes. Recipients have worked for years and have contributed to the Social Security trust fund in the form of Social Security taxes – received under either the Federal Insurance Contributions Act for employees or the Self-Employment Contributions Act for the self-employed. These taxes translate into Social Security “credits.” Qualified dependents of a disabled work may also receive benefits even though they may not have worked.

The amount needed for a work credit changes from year to year. In 2021, for example, you earn one credit for each $1,470 in wages or self-employment income. When you’ve earned $5,880, you’ve earned your four credits for the year.

Supplemental Security Income (SSI)

SSI provides payments to people with disabilities who have low income and few resources. Although Social Security manages the program, the SSI program is funded by general tax revenues and is not paid for from Social Security taxes. Also, SSI benefits are not based on your work history.

How You Qualify

It’s important to know which benefits you may qualify to receive. Please read our publications, Disability Benefits and Supplemental Security Income (SSI), for more information. You can also see if you meet the requirements for disability benefits on our How You Qualify page. When you apply for either program, we’ll collect medical and other information from you and make a decision about whether or not you qualify for benefits.

You can apply online for retirement, spouse’s, Medicare, or disability benefits.
