If you receive Social Security Disability Insurance — or are applying for it — the term Substantial Gainful Activity (SGA) will come up repeatedly. It's one of the most concrete rules in the SSDI program, and it directly determines whether you can work at all while receiving benefits.
Substantial Gainful Activity is the SSA's term for a level of work activity and earnings significant enough to suggest a person is not, in the program's terms, disabled. The SGA limit is the monthly earnings threshold SSA uses to make that determination.
If your earnings exceed the SGA limit, SSA generally considers you capable of substantial gainful activity — which can affect both your initial eligibility and your continued right to benefits.
For 2025, the SGA limit is $1,620 per month for most SSDI recipients. A separate, higher threshold applies to people who are blind: $2,700 per month in 2025. These figures adjust annually based on changes in national average wages, so it's worth checking the SSA website for the current year's figures before making any decisions.
The SGA threshold isn't just a rule that applies once. It plays a role at multiple points in your SSDI journey.
During the application process: When SSA evaluates a new claim, one of the first things they check is whether you are currently working above SGA. If you are, SSA will typically deny the claim at step one of their five-step sequential evaluation — before even reviewing your medical records. This is why earnings at or above the SGA limit during an application can stop a claim cold.
After approval: Once you're receiving SSDI benefits, the SGA limit governs whether your benefits continue if you return to work. Working above SGA during certain periods can trigger a cessation of benefits.
During the Trial Work Period and Extended Period of Eligibility: These are built-in work incentives that give beneficiaries room to test their ability to work without immediately losing benefits — but SGA is the line that ultimately matters once those periods end.
SSDI includes a Trial Work Period (TWP) that allows beneficiaries to work for up to nine months (not necessarily consecutive) within a rolling 60-month window without the SGA limit affecting their benefits. During this period, you receive full SSDI benefits regardless of how much you earn, as long as you report the work.
The nine TWP months are tracked using a separate, lower earnings trigger — in 2025, any month in which you earn more than $1,110 counts as a trial work month.
After using all nine trial work months, SSA reviews your earnings. If you're working above the SGA limit, your benefits may stop. This is where the SGA threshold becomes the deciding line.
Following the Trial Work Period, there's a 36-month Extended Period of Eligibility (EPE). During this window, you can receive benefits for any month in which your earnings fall below the SGA limit — even if you've already used your trial work months. If your earnings drop below SGA during the EPE, your benefits can be reinstated without filing a new application.
Once the EPE ends, working above SGA typically ends benefits entirely, with no automatic reinstatement option.
Gross earnings aren't always what SSA counts against the SGA limit. Impairment-Related Work Expenses (IRWEs) — costs you pay out of pocket for items or services that allow you to work because of your disability — can be deducted from your gross earnings before SSA applies the SGA test.
Examples might include certain medications, medical devices, or transportation costs directly tied to your disability. What qualifies as an IRWE depends on SSA's specific criteria and your individual situation.
The SGA calculation gets more complex for self-employed individuals. SSA doesn't rely solely on income in those cases — they also look at the nature and amount of work performed and may apply different tests to determine whether activity rises to the level of SGA.
Additionally, non-cash benefits provided by an employer — like free housing or meals — can sometimes factor into the SGA calculation, depending on how SSA evaluates them.
| Rule | 2025 Monthly Threshold |
|---|---|
| SGA limit (non-blind) | $1,620 |
| SGA limit (blind) | $2,700 |
| Trial Work Period trigger | $1,110 |
These amounts adjust annually. Always verify current figures with SSA.
How SGA applies in practice depends on more than the dollar figure. It intersects with:
Two people earning the same monthly amount can end up in very different positions depending on these factors. Someone early in their Trial Work Period faces a different calculation than someone in the Extended Period of Eligibility — or someone who has never been approved and is still in the application process. 💡
The SGA limit is one of the most straightforward rules in SSDI — but applying it to your actual earnings, work history, and benefit status is where things get specific.
