In the U.S., Social Security Disability Insurance (SSDI) is a federal insurance program that is payroll funded, that is, the program is funded by a tax withheld from employees’ paychecks. It is sometimes also called Disability Insurance Benefits (DIB) or “Title II.” If an individual is unable to work due to a disability, Social Security Disability will provide income until that individual is able to return to work, or, in the case that the disability is permanent, SSDI guarantees income. There are fixed and stringent requirements in order to qualify for Social Security Disability and it is essential that all paperwork submitted is accurate and complete.
