Payroll taxes are the main source of funding for Social Security Disability benefits. SSD benefits are available to those who have worked for a certain number of years and have made the necessary contributions to the Social Security trust fund through various taxes. However, the Social Security Administration also administers disability benefits through another program-Supplemental Security Income.
SSI is a means-tested program. Payments are provided to disabled individuals who have few resources and low income, regardless of their work history. California residents who are considering applying for benefits must understand the SSA's strict definition of "disability" and meet it by providing the necessary medical and financial documents.
