Substantial Gainful Activity (SGA)

Substantial gainful activity is the standard Social Security uses to decide whether work activity is inconsistent with a finding of disability. 20 CFR 404.1572 defines it in two parts: substantial work activity "involves doing significant physical or mental activities", and gainful work activity is work "that you do for pay or profit ... whether or not a profit is realized". Both halves must be present. The regulation adds that work may be substantial "even if it is done on a part-time basis or if you do less, get paid less, or have less responsibility than when you worked before", and that ordinary activities such as self-care, household tasks, hobbies, therapy, school attendance and club activities are generally not substantial gainful activity. For 2026 the monthly earnings amount is $1,690 for a claimant who is not blind and $2,830 for one who is statutorily blind.

The dollar amount is a guide applied to earnings, and it does not run in both directions. 20 CFR 404.1574(a)(1) says that "generally, if you worked for substantial earnings, we will find that you are able to do substantial gainful activity", and then adds the sentence that is easy to read past: "however, the fact that your earnings were not substantial will not necessarily show that you are not able to do substantial gainful activity". So the threshold is close to conclusive when it is exceeded and merely indicative when it is not. Saying that earning under the amount proves disability inverts the regulation.

Four adjustments shrink the earnings the agency actually compares. The first is the subsidy: 404.1574(a)(2) says work is subsidized "if the true value of your work, when compared with the same or similar work done by unimpaired persons, is less than the actual amount of earnings paid to you", and the value of the subsidy is subtracted before the comparison. The second is impairment-related work expenses, defined at 404.1576 as the reasonable costs of items and services a person needs because of their impairment in order to work, deductible even where the same item also serves daily living, and deductible only to the extent the person actually pays and is not reimbursed. The third is averaging under 404.1574a, since the comparison is normally made against average monthly earnings rather than a single month. The fourth is the unsuccessful work attempt.

The unsuccessful work attempt has two hard edges. Under 404.1574(c), work of six months or less that the impairment forced the person to stop or cut below the substantial gainful activity level does not show an ability to work. But it must be preceded by "a significant break in the continuity of your work", which the regulation defines as being out of work at least 30 consecutive days, or being forced by the impairment to change to a different type of work or a different employer. And work performed at the substantial gainful activity level for more than six months is never an unsuccessful work attempt, "regardless of why it ended".

After 24 months of benefits, the earnings figure stands alone. 404.1574(b)(3)(iii) says that where a beneficiary has received Social Security disability benefits for at least 24 months, the agency will not consider other information in addition to earnings when evaluating whether work shows substantial gainful activity for a cessation decision. Before that point, the agency may look at comparability with unimpaired workers and the worth of the work, particularly where the beneficiary can influence how much and when they are paid.

Two categories of activity are excluded by regulation. Payments from federal volunteer programs authorized by the Domestic Volunteer Service Act of 1973 or the Small Business Act, which the regulation lists by name including Volunteers in Service to America, the Foster Grandparent Program and the Service Corps of Retired Executives, do not count as earnings, and the volunteer service itself is disregarded. So is service as a member or consultant of a federal advisory committee established under the Federal Advisory Committee Act, unless that service is part of the person's job.

The self-employed are evaluated under a different regulation. 20 CFR 404.1575 says the agency "will not consider your income alone because the amount of income you actually receive may depend on a number of different factors, such as capital investment and profit-sharing agreements", and applies three tests: whether the person renders services significant to the business and receives substantial income from it; whether the work is comparable in hours, skills, energy, duties and responsibilities to that of unimpaired people in the same business; and whether the work is clearly worth the guide amount in terms of its value to the business. Operating a one-person business makes any services significant by definition, and in a multi-person business the test is more than half the management time, or management services for more than 45 hours a month.

Two amounts, two legal sources. The higher amount for statutorily blind claimants is set by a formula in the Social Security Act itself, while the non-blind amount rises under regulation. That is why one can change in a year the other does not, and it is worth knowing before reading anything into a year in which only one moved. The higher blind amount belongs to Title II benefits. Supplemental Security Income treats blindness differently: 20 CFR 416.984 says there is "no requirement that you be unable to work in order for us to find that you are blind", so the earnings question there runs through the income and resource rules instead.

For an employee the sequence is: start with gross earnings, subtract any subsidy, subtract impairment-related work expenses, average the result over the relevant period, and compare that figure to the monthly amount for the year. Work that fails the comparison is examined again for an unsuccessful work attempt. Only then does the agency reach a conclusion about the work.

A hypothetical example, with invented figures. Marcus returns to a warehouse job and is paid $2,100 a month gross. His employer keeps him on with close supervision and simplified tasks, and the true value of his output compared with an unimpaired worker doing the same job is $500 a month less than he is paid, which makes $500 of his pay a subsidy. Because of his impairment he pays $180 a month for specialized transportation he needs in order to get to work, which is an impairment-related work expense. His countable earnings are therefore $2,100 minus $500 minus $180, or $1,420 a month. That $1,420, not the $2,100 on his pay stub, is the figure the agency compares with the substantial gainful activity amount for the year. If Marcus were self-employed rather than an employee, this arithmetic would not be the deciding step, because the agency would first evaluate the significance of his services to his own business under three separate tests, and would reach a dollar comparison only inside one of them and on a differently computed figure.

Pros

• The two-part definition is a real legal test rather than a pure income cutoff, so someone earning above the amount can still explain why the work was not substantial and gainful.
• Subsidies and impairment-related work expenses are subtracted, which recognizes that a paycheck can overstate what a person is actually able to do.
• The unsuccessful work attempt rule means a genuine failed return to work does not count against the claimant.
• After 24 months of benefits, evaluation is on earnings alone, which makes the outcome more predictable for someone attempting work.

Cons

• The comparison is monthly, so a single strong month can raise a question that an annual view would not.
• Earnings below the amount are not proof of disability, and a claimant who treats the figure as a safe harbor can be surprised.
• Subsidies and impairment-related work expenses have to be documented and are easy to lose for want of records.
• The unsuccessful work attempt requires a 30-day break beforehand and is capped at six months, so a longer attempt counts against the claimant no matter why it ended.
• The self-employed face a value-of-services test that is harder to predict than a dollar threshold, and can be found to be working substantially in a year the business made no profit.
