What is Substantial Gainful Activity (SGA) under Social Security Disability?
If you earn enough income each month, Social Security won’t consider you eligible for disability benefits. How do they decide what is too much income?
By determining whether your earnings constitute “substantial gainful activity,” or SGA.
SGA is the limit Social Security sets on the earnings you can make each month and still receive Social Security Disability—which are meant for people who can’t work.
If you’re earning over the limit, Social Security will likely deny your benefits before even looking at your medical records and health impairments. If you’re already receiving benefits, earning more than the SGA limit will put them at risk.
Social Security is clear that disability benefits are for people with physical or mental impairments so severe that they can no longer work a significant amount. If you can’t work, you shouldn’t be earning much from any job.
Substantial gainful activity is rooted in Social Security’s strict definition of a disability: that you have a medically recognized impairment or a collection of symptoms that will last at least a year and significantly reduce or halt your capacity to work.
- “Substantial” refers to meaningful duties you must perform in a job. This can be physical labor, or it can be mental tasks required to get the job done.
- “Gainful” refers to an activity you do for pay or profit.
- “Activity” is the ability to pursue and perform this labor.
Social Security adjusts its SGA limit every year to account for cost-of-living increases. As of 2026, a non-blind individual could not earn more than $1,690 a month and still be eligible for disability benefits. A legally blind person had a higher limit: $2,830 per month.
If you’re concerned about your earnings and eligibility for disability benefits, you can reach out to a disability attorney for more information about your particular situation.

How Does Social Security Calculate Your SGA?
When Social Security reviews your disability benefits application, they look at your substantial gainful activity first. After all, it’s the quickest way to rule out a claim.
How does Social Security figure out your SGA?
It starts with your pre-tax, gross income.
For wage earners, Social Security will want to see pay stubs from the most recent period when there wasn’t a significant change in your employment or pay. For self-employed applicants, they’ll look at your net earnings and compare your work to individuals who are not disabled and perform the same or similar work.
Social Security calculates a monthly average of your pay to create a base amount for your SGA.
Then it will deduct certain expenses from its calculation of your income for SGA purposes, making it easier to stay under the income limit. These include:
- The cost of medical devices or services that allow you to continue to work
- The cost of special accommodations at your office or worksite
- The value of employer-provided subsidies, such as giving you lighter duties but not reducing your pay
Money you or your employer spend on those items reduces what Social Security considers to be your true income that applies under the SGA standard.
And SGA doesn’t count passive income such as payments from pensions or investments.
The inability to work is the core problem disability benefits address, so Social Security Disability Insurance (SSDI) focuses on income you make from working, not other financial resources.
The picture is a little different for Supplemental Security Income (SSI) disability benefits.
You must be under SGA to qualify for SSI, too, but SSI focuses on overall economic need, not just ability to work. So SSI factors in savings, investments, property or other assets in your ability to get benefits and how much you receive.

What if Your Earnings from Working Go Up after Starting Disability Benefits?
Once you start Social Security Disability benefits, you must be careful to stay below the annual SGA earnings limit, or you might lose benefits.
That doesn’t mean, however, that you can’t work at all.
Simply put, if you earn less than the SGA rate, you can still receive disability benefits.
Social Security requires you to report work activity, regardless of its impact on your SGA eligibility. That reporting may trigger a review of your case.
Social Security also allows you to test whether you can return to work without penalizing you for trying.
Under a “trial work period,” you can work up to nine months in a five-year period and Social Security won’t consider your earnings against your SGA limit.
Likewise, if you want to test if you can maintain a job after your trial work period ends, Social Security will let you receive benefits during months when your earnings fall below the SGA limit.
This is called the “extended period of eligibility,” and it lasts for three years after the trial work period.
However, there are other requirements. A trial work period and extended period of eligibility are only available to SSDI recipients, not those who receive SSI. In addition, you must have a 12-month period of disability prior to becoming eligible.
Whether you’re trying to figure out if you qualify for disability benefits, you’ve been denied by Social Security, or you already receive benefits and are worried about losing them, the Chicago disability attorneys at Nash Disability can help.
