Retirement Benefits: These benefits are available to workers who have paid into the Social Security system through payroll taxes during their working years. Individuals can start receiving reduced retirement benefits as early as age 62, but full benefits are available at the full retirement age, which varies depending on the year of birth. Delaying benefits beyond full retirement age can increase the monthly benefit amount.

Disability Benefits: Social Security Disability Insurance (SSDI) provides benefits to individuals who are unable to work due to a qualifying disability. To be eligible, individuals must have a sufficient work history and meet specific medical criteria.

Survivor Benefits: These benefits are paid to the surviving spouses, children, or dependents of deceased workers who paid into the Social Security system. The amount of the benefit depends on the deceased worker's earnings record.

Supplemental Security Income (SSI): Although administered by the Social Security Administration, SSI is a separate program funded by general tax revenues (not Social Security taxes). It provides financial assistance to elderly, blind, or disabled individuals with limited income and resources.
