If you receive Social Security Disability Insurance — or are applying for it — there's one number that carries more weight than almost any other: the Substantial Gainful Activity (SGA) limit. In 2025, that number determines whether SSA considers you disabled enough to receive benefits at all, and whether working while on SSDI puts your payments at risk.
Substantial Gainful Activity is the SSA's measure of whether someone is working at a level that's considered significant enough to disqualify them from SSDI. The agency doesn't simply ask whether you're working — it asks whether you're earning above a specific monthly threshold.
If you earn more than the SGA limit, SSA generally concludes you are capable of engaging in substantial work, which can affect both your initial eligibility and your ongoing benefit status.
SGA applies at two distinct moments:
SSA adjusts the SGA threshold annually based on changes in the national average wage index. These figures adjust each year, so it's worth confirming the current amounts directly with SSA.
| Category | 2025 Monthly SGA Limit |
|---|---|
| Non-blind disability | $1,620/month |
| Statutory blindness | $2,700/month |
The higher limit for statutory blindness reflects a separate rule written into the Social Security Act. If you receive SSDI based on a visual impairment that meets SSA's definition of statutory blindness, the higher threshold applies to you.
These are gross earnings figures — meaning SSA looks at what you earn before taxes, not what you take home.
Not every dollar you receive counts as SGA earnings. SSA evaluates countable earned income, which means wages from work activity or net earnings from self-employment. Some items are excluded or can be deducted:
Self-employment is evaluated differently than wage employment. SSA may look at the value of your work to the business, the time you spend, and comparable wages in similar roles — not just what the business pays you.
Once you're approved for SSDI, you don't immediately lose benefits the moment you exceed the SGA limit. SSA has a Trial Work Period (TWP) that allows you to test your ability to return to work without immediately losing benefits.
During the TWP — which consists of 9 months (not necessarily consecutive) within a rolling 60-month window — you can earn any amount and still receive full SSDI payments, regardless of whether your earnings exceed SGA. In 2025, a month counts as a TWP service month if you earn more than $1,110 (this threshold also adjusts annually).
After you've used all 9 TWP months, the Extended Period of Eligibility (EPE) begins. During the 36-month EPE, SSA will reinstate your benefits in any month your earnings fall below the SGA limit — without requiring a new application.
The SGA limit affects people very differently depending on where they are in the SSDI process:
Applicants currently working: Earning above $1,620/month (for non-blind claimants) at the time of application is a significant obstacle. SSA may stop the review before even looking at medical records.
Approved beneficiaries returning to part-time work: Someone working limited hours in a low-wage or accommodated role may stay comfortably below SGA while still generating income — particularly if they can deduct IRWEs.
Self-employed beneficiaries: The SGA calculation is more complex. SSA uses three separate tests to evaluate self-employment income, and the outcome depends heavily on how much the individual contributes to the business and what comparable work would pay.
Claimants with fluctuating income: Monthly earnings that vary — rising above SGA in some months, falling below in others — create a nuanced picture. SSA generally evaluates earnings month by month, not as an annual average.
Beneficiaries using Ticket to Work: Participants assigned to an Employment Network may receive additional protections during work activity, including suspension of continuing disability reviews while the ticket is in use.
The 2025 SGA limit of $1,620 for non-blind recipients and $2,700 for those meeting statutory blindness criteria are clear, published thresholds. What's less clear is how your specific earnings, deductions, work arrangements, benefit history, and disability category interact with those numbers. Whether your income is countable, whether you've entered the trial work period, and how SSA would evaluate your particular work activity all depend on facts that vary from one person to the next.
The threshold is the same for everyone. What it means for your benefits is not.
