Requirements for Social Security Disability Insurance are the same from state to state. They are no different in South Carolina than they are anywhere else in the country, and there is no minimum age. However, the requirements do change slightly based on your age.The basic requirement: In order to qualify for disability , you have to have a history of earned income. You typically earn one credit for every quarter you earn a set amount. In 2013, you have to make at least $1,160 in a quarter to get a credit for that quarter. The amount of income required per quarter changes as average incomes increase. How it works when you're young: The younger you are, the less earned income you have to prove in order to qualify for disability.
- South Carolina disability applicants age 24 or younger must have earned at least six credits in the three years ending when their disability started. That means they will need to have worked at least half of the three years before they became disabled.
- Applicants aged 24 to 31 can qualify if they have worked at least half the time since they turned 21. That means if you are 25, you will need credit for at least two years of work - 8 credits - for the four years between 21 and 25. If you are 30, you will need credit for at least four and a half years of work - 9 credits.
