Social Security Disability Insurance

Social Security Disability Insurance (SSDI) is an integral part of Social Security. It provides benefits to people who cannot work due to a medical condition that is expected to last at least one year or result in death. These benefits, like Social Security retirement benefits, are funded by a portion of the payroll taxes paid by workers and employers.

In 2024, SSDI provided vital income support to more than 8.3 million workers with disabilities and their families. This represents 12.3 percent of those receiving Social Security benefits. SSDI benefits are particularly significant to older workers. They are more likely than younger workers to have chronic illnesses and other disabling conditions.
