You must first have worked in jobs covered by Social Security in order to be eligible to apply for Social Security disability benefits.
In addition to the work requirement, you must also have a medical condition that meets the SSA definition of disability. Basically, the SSA will pay monthly benefits to individuals that are unable to work for over a year because of an accepted disability.
How Much Do I Need To Work To Qualify For Disability?
The number of work credits you need to qualify for disability benefits depends on your age when you become disabled. You need 40 work credits, 20 of which were earned in the last 10 years ending with the year you become disabled.
The Social Security Administration bases work credits on your total yearly wages or self-employment income. You can earn up to four work credits each year.
