In this video attorney Francis Jackson of the law firm of Jackson & MacNichol conducts a live Q & A session on Social Security Disability Training and answers the question: How many earning quarters are necessary before a person is eligible for Social Security Disability and is each quarter one-quarter of a year? Normally it is 20 out of the last 40. It used to be that they looked at your earnings literally by quarters in 3 month periods, but now you can earn an entire year’s quarters in the first month if you earn enough. It is a question of earnings. They keep adjusting it every year, currently it is $4,000. So if you are a highly paid executive and you earn more than 12 months this month you have earned your quarters for the year, but you can never get more than 4 per year.
