Social Security follows a sequential evaluation in making decisions on disability claims. Step one of the sequential evaluation is determining whether an individual is engaging in substantial gainful acitivity(SGA). In 2013, SGA for a non-blind individual, is having more than $1040 per month in earnings. When an individual is actually engaging in SGA , Social Security makes a finding that the individual is not under a disability without consideration of either medical or vocational factors. In other words if you are making more than $1040 per month, Social Security makes a decision that you are not disabled without every looking your medical evidence.
