How Does Working Affect SSDI Through Substantial Gainful Activity?
Verified against SSA POMS as of September 16, 2026
The short answer
Substantial Gainful Activity (SGA) refers to work that is both significant and gainful. According to 20 CFR 404.1510 and 416.910, SGA involves doing significant duties for pay or profit. SSDI eligibility can be influenced by engaging in SGA, with specific guidelines for employees and self-employed individuals found in sections 20 CFR 404.1574, 404.1575, and related sections.
Definition of Substantial Gainful Activity
Substantial Gainful Activity (SGA) is defined as work that involves significant physical or mental activities and is done for pay or profit. This definition is consistent in 20 CFR 404.1510 and 416.910, where both sections describe SGA as significant and productive work, intended for profit (§ 404.1510, § 416.910).
20 CFR 404.1510 View source ›Understanding SGA for Employees
For employees, SGA is primarily evaluated based on earnings. According to 20 CFR 404.1574 and 416.974, earnings exceeding certain thresholds can indicate SGA. Employee earnings are assessed after removing any subsidies or costs related to impairments, ensuring that only earnings directly tied to productivity are considered (§ 404.1574, § 416.974).
20 CFR 404.1574 View source ›Criteria for Self-Employed Individuals
For self-employed individuals, SGA is evaluated through a series of tests that consider the significance of the individual's contributions to the business and the income derived from it. 20 CFR 404.1575 outlines three tests: significant services and substantial income, comparability to unimpaired individuals, and the overall worth of the work relative to community pay scales (§ 404.1575).
20 CFR 404.1575 View source ›Special Conditions Affecting SGA
Work done under special conditions, such as sheltered environments or with special accommodations, may not constitute SGA even if earning levels indicate otherwise. Situations include receiving significant assistance or working under altered circumstances due to impairment (§ 404.1573, § 416.973).
20 CFR 404.1573 View source ›Unsuccessful Work Attempts
An unsuccessful work attempt is defined as work lasting six months or less that ends due to impairment-related reasons. This is not considered SGA if specific conditions are met, as described in 20 CFR 404.1574(c) and 416.974(c), which include stopping work or reducing work due to impairment (§ 404.1574, § 416.974).
