Social Security Disability Insurance, or SSDI, is a Federal program that provides aid to people who are unable to achieve gainful employment as a result of a permanent disability. SSDI is financed by the Social Security tax. Therefore, any person that qualifies as disabled according to the definition provided by Social Security Administration (SSA), and who has paid Social Security taxes long enough to achieve sufficient work credits, can qualify for SSDI.
If you have worked approximately 5 full years out of the last 10 years, and you have become unable to work, then Social Security Disability Insurance Benefits may be available. This insurance benefit is available only to those who have paid in, and your ability to qualify is not affected by your household income or net worth.
