How is Substantial Gainful Activity (SGA) determined?
Substantial gainful activity can be measured in two ways: Total actual monthly wages (dollars) any work that generates gross (before taxes) earned income that is equal to or greater than $940 (SGA) as of 2008 ($1,570 for blind beneficiaries). Substantial gainful activity can be the dollar value the Social Security Administration places on work activity even if wages are not paid. If SSA places the value of work to be $940 or more the work is considered Substantial Gainful Activity as of 2008 ($1,570 for blind beneficiaries).
