SGA stands for "substantial gainful activity" and is a term used by the Social Security Administration (SSA) in the United States to describe a level of work activity and earnings. It is used to determine eligibility for Supplemental Security Income (SSI) or Social Security Disability Insurance (SSDI) benefits. To be eligible for disability benefits, a person must be unable to engage in substantial gainful activity (SGA) . The SSA sets a monthly threshold for SGA, and if a persons income exceeds that amount, they may not be eligible for disability payments. For 2023, the monthly SGA amount for statutorily blind individuals is $2,460, and for non-blind individuals, the monthly SGA amount is $1,470. The SSA evaluates SGA based on monthly income, but various other factors may also be considered.
