Social Security Administration (online SSA board) http://www.ssa.gov/dibplan/dwork2.htm WHAT CAN CAUSE BENEFITS TO STOP? Two things can cause us to decide that you are no longer disabled and to stop your benefits. * Your disability benefits will stop if you work at a level we consider "substantial." In 2011, average earnings of $1,000 or more per month ($1,640 or more per month if you are blind) are usually considered substantial. * Your disability benefits also will stop if we decide that your medical condition has improved to the point that you are no longer disabled. You are responsible for promptly reporting any improvement in your condition, if you return to work, and certain other events as long as you are receiving disability benefits. The booklet we send you when your application is approved explains what you need to report to us.
