How is Substantial Gainful Activity (SGA) defined in relation to work requirements?

The definition of Substantial Gainful Activity (SGA) is primarily focused on the earnings level an individual can achieve while still receiving cash benefits from Social Security Disability Insurance (SSDI) or Supplemental Security Income (SSI). SGA is measured by whether an individual's earnings exceed a specific threshold set by the Social Security Administration, which is adjusted annually.

When individuals earn above this threshold, it generally indicates that they are engaged in substantial work activity, which can affect their eligibility for benefits. Therefore, option B accurately captures this definition, emphasizing that SGA relates to a level of earnings rather than the nature of the work or the hours worked.

Work requirements related to SGA typically do not focus on part-time versus full-time status, physical effort, or the classification of work. As a result, the other options do not convey the specific regulatory focus of SGA as it pertains to earnings levels impacting cash benefits. Understanding SGA is crucial for professionals working within the framework of work incentives and social security programs.
