What it means
To receive disability benefits from Social Security, an applicant must have a medical condition that prevents them from doing substantial gainful activity. The term has two parts: the work must be substantial, meaning it involves significant physical or mental effort, and gainful, meaning it is done for pay or profit.
The test is mainly about earnings. If a person's countable monthly earnings are above the current threshold, the agency generally concludes that they are able to engage in such activity, and the claim fails at an early stage.
The threshold differs for people who are blind, and it is adjusted annually in line with average wages. Because it changes, anyone planning around it should check the figure published by the Social Security Administration for the relevant year.
Countable earnings are not always the same as the amount on the payslip. Costs of work that arise directly from the person's impairment, called impairment-related work expenses, can be deducted, and employer subsidies may reduce the value of the work counted.
The rule sits alongside other tests. The agency also asks whether the condition is severe, whether it is expected to last at least twelve months or end in death, and whether the person can do any other work given age, education and experience.
Passing the earnings test does not by itself prove entitlement to benefits. This is relevant to employers, advisers and families, because part-time or trial work can affect a benefit claim.
There are rules, such as a trial work period, that let people test their ability to work without losing benefits at once, and professional advice is wise before taking a job.
In practice
Real-world examples.
Example
A former warehouse worker with a back condition takes a part-time job paying well below the threshold. The agency considers it likely that he is not engaged in substantial gainful activity. He keeps records of his hours and pay in case he is asked to confirm them.
Example
A software tester with a hearing impairment pays for a specialist device so she can work. The cost is deducted as an impairment-related work expense, which lowers her countable earnings.
Example
A financial adviser helping a client with a disability checks the current threshold before the client accepts a new contract. They plan the hours so that earnings stay in line with the benefit rules. The adviser also writes down the steps to report any change in earnings promptly to the agency.
Formula
Calculation
The test compares countable monthly earnings with the threshold:
Countable earnings = Gross monthly earnings - Impairment-related work expenses - Subsidies
Substantial gainful activity applies if Countable earnings are above the threshold
The actual threshold changes every year, so this example uses a hypothetical monthly threshold of $1,600. A person earns $1,900 a month and has $400 of impairment-related work expenses, so countable earnings are $1,900 - $400 = $1,500. Because $1,500 is below the hypothetical $1,600 threshold, this work would not count as substantial gainful activity, whereas earnings of $1,900 with no deductions would.Case study
Seen in the real world.
Dana Whitfield is an illustrative, fictional person with a long-term illness who received disability benefits and wanted to return to work part-time. She was offered a position paying $2,000 a month, while the threshold in this example was $1,600.
Her adviser explained that accepting the job could affect her benefits, but that a trial work period would allow her to test the position for a limited time. The adviser also helped her calculate impairment-related expenses of $300 a month for transport and equipment.
In this illustrative story, her countable earnings of $1,700 still exceeded the threshold, so she decided to start with fewer hours and stay under the limit while her health stabilised. A year later, she moved to full-time work with a clear understanding of how and when her benefits would end. She kept her payslips and expense receipts in case the agency asked to review them.
Watch out
Common mistakes.
- Assuming the threshold is fixed, when it is adjusted each year.
- Using gross pay without considering allowable deductions for work costs caused by the impairment.
- Taking work without telling the agency, which can lead to overpayments that must be repaid.
Questions
People also ask.
Does substantial gainful activity apply to all benefits?
It applies mainly to Social Security disability programmes, and rules differ by programme.
Can unpaid or volunteer work count?
Work can count if it is productive and would normally be paid, although the agency looks at the facts of each case.
Where do I find the current threshold?
The Social Security Administration publishes the amount each year on its website, and a benefits adviser can confirm how it applies to your circumstances.
