If you're receiving SSDI benefits — or applying for them — one number shapes almost every work-related decision you'll make: the Substantial Gainful Activity (SGA) limit. For 2025, the SGA threshold for non-blind SSDI recipients is $1,620 per month.
That figure isn't arbitrary. It's the line the Social Security Administration (SSA) uses to define whether someone is working "substantially." Cross it, and SSA may determine you're no longer disabled under their definition — regardless of your medical condition.
Substantial Gainful Activity is the SSA's standard for measuring work activity. It applies at two critical points:
The SGA limit is a gross earnings threshold, not a net one. SSA looks at what you earn before taxes, though certain deductions — like impairment-related work expenses — can sometimes reduce the countable amount.
| Category | 2025 Monthly SGA Limit |
|---|---|
| Non-blind SSDI recipients | $1,620/month |
| Blind SSDI recipients | $2,700/month |
The higher threshold for blind individuals reflects a long-standing statutory distinction in the Social Security Act. Both figures adjust annually based on changes in national average wages, so they typically increase each year — though the timing and amount vary.
The SGA test isn't always as simple as comparing your paycheck to $1,620. Several factors shape how SSA actually counts your earnings:
Self-employment income is evaluated differently than wages. SSA may look at the value of your work, not just your profit, and uses specific tests to assess whether self-employment rises to the level of SGA.
Subsidized work — situations where an employer pays you more than your work is worth due to your disability — may be adjusted downward when SSA calculates countable earnings.
Impairment-related work expenses (IRWEs) are out-of-pocket costs related to your disability that allow you to work. Things like medication, adaptive equipment, or specialized transportation may be deducted from gross earnings before the SGA comparison is made.
Unsuccessful work attempts — periods of work lasting less than six months that end due to your disability — may not count against you during the application process.
Each of these adjustments depends heavily on the specifics of your situation, your condition, and how your work is structured.
At the initial application stage, SSA first asks: Are you engaging in SGA? If yes, the claim is typically denied immediately. This is called a Step 1 denial in SSA's five-step sequential evaluation process.
This means two people with identical medical conditions can have very different outcomes at Step 1 — simply based on how much they're earning at the time of application. If you're working part-time and your earnings are consistently below $1,620 gross per month, SSA proceeds to evaluate your medical evidence. If you're above that threshold, the medical review may never happen.
Once approved, SSDI recipients aren't necessarily cut off the moment they earn above SGA. SSA builds in a structured return-to-work safety net:
Trial Work Period (TWP): You can test your ability to work for up to 9 months (within a rolling 60-month window) without affecting your SSDI benefits, regardless of how much you earn. In 2025, any month in which you earn more than $1,110 counts as a trial work month.
Extended Period of Eligibility (EPE): After your TWP ends, you enter a 36-month window during which SSA will review your earnings each month. If your earnings fall below SGA in any month during the EPE, you can receive benefits for that month. If they stay above SGA, your benefits stop — though they can be reinstated without a new application if your earnings drop again during this window.
Cessation and termination are different things. Benefits cease when you exceed SGA after the TWP, but formal termination doesn't happen immediately. Understanding where you are in this timeline matters enormously for what options are available to you.
The $1,620 figure is fixed for 2025. Everything else is shaped by circumstances:
Two people both earning $1,500 per month can be in very different positions depending on these factors. One may be safely below SGA with no adjustments needed. Another may have countable income calculated differently based on their work arrangement. 💡
The 2025 SGA limit of $1,620 per month for non-blind SSDI recipients is a clear, published number — but what it means for any individual depends entirely on where they are in the SSDI process, how their work activity is structured, and what deductions or protections may apply to their specific case. The threshold is the same for everyone. The outcome is not.
