Substantial Gainful Activity

Updated October 19, 2004
Introduction To be eligible for disability benefits, a person must be unable to engage in substantial gainful activity (SGA). A person who is earning more than a certain monthly amount (net of impairment-related work expenses) is ordinarily considered to be engaging in SGA. The amount of monthly earnings considered as SGA depends on the nature of a person's disability. The Social Security Act specifies a higher SGA amount for statutorily blind individuals; Federal regulations specify a lower SGA amount for non-blind individuals. Both SGA amounts increase with increases in the national average wage index.
Amounts for 2005 The monthly SGA amount for statutorily blind individuals for 2005 is $1,380. For non-blind individuals, the monthly SGA amount for 2005 is $830. Shown below are details on how these amounts were determined.
SGA for the Blind
[does not apply to Supplemental Security Income (SSI) benefits]
The monthly SGA amount for statutorily blind individuals for 2005 is such SGA amount for 1994 multiplied by the ratio of the national average wage index for 2003 to that for 1992, or, if larger, such SGA amount for 2004 ($1,350). If the amount so calculated is not a multiple of $10, we round it to the nearest multiple of $10.

Amounts in
formula
1994 monthly SGA amount$930
1992 average wage index$22,935.42
2003 average wage index$34,064.95
Computation$930 times ($34,064.95 divided by $22,935.42) equals $1,381.29, which rounds to $1,380.
Higher amount$1,380 exceeds $1,350, so the amount for 2005 is $1,380

SGA for the Non-Blind Disabled
(applies to Social Security and SSI benefits)
The method used to adjust the SGA for non-blind individuals is similar to that used for blind individuals and was published in the Federal Register (FR 65 82905) on December 29, 2000. The monthly SGA amount for non-blind disabled individuals for 2005 is such SGA amount for 2000 multiplied by the ratio of the national average wage index for 2003 to that for 1998, or, if larger such SGA amount for 2004 ($810). If the amount so calculated is not a multiple of $10, we round it to the nearest multiple of $10.

Calculation details
Amounts in
formula
2000 monthly SGA amount$700
1998 average wage index$28,861.44
2003 average wage index$34,064.95
Computation$700 times ($34,064.95 divided by $28,861.44) equals $826.20, which rounds to $830
Higher amount$830 exceeds $810, so the amount for 2005 is $830

Trial work period After a person becomes eligible for disability benefits, the person may attempt to return to the work force. As an incentive, we provide a trial work period in which a beneficiary may have earnings and still collect benefits.
