If you receive Social Security Disability Insurance — or are applying for it — one number matters more than almost any other: the Substantial Gainful Activity (SGA) limit. For 2025, that number has been updated, and understanding what it means (and what it doesn't) can help you make informed decisions about working while on SSDI.
Substantial Gainful Activity is the SSA's measure of whether someone is working at a level that, in the agency's view, demonstrates they are not disabled under federal rules. SSDI is designed for people who cannot work at a meaningful level due to a medical condition. SGA is the line that separates "not working substantially" from "working too much to qualify."
SGA applies at two critical points:
SSA adjusts SGA thresholds annually based on changes in the national average wage index. For 2025:
| Category | Monthly SGA Limit (2025) |
|---|---|
| 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 how SSA treats that specific impairment category.
These figures apply to gross earned income — not take-home pay. SSA may make certain deductions (such as for impairment-related work expenses) that can reduce the countable amount, but the starting point is always gross earnings.
When you apply for SSDI, one of the first things SSA checks is whether you're currently working above SGA. This is called a Step 1 evaluation in the five-step sequential evaluation process. If your earnings exceed the SGA limit in the months leading up to or during your application, SSA will deny the claim at Step 1 — before even reviewing your medical records.
This is why many applicants either stop working before applying or reduce their hours significantly. Working below SGA doesn't automatically mean you'll be approved, but working above it generally means you won't be — at least not without additional context.
Once approved for SSDI, you're not permanently barred from working. SSA has several structured work programs designed to ease the transition back to employment without immediately cutting benefits.
The Trial Work Period allows you to test your ability to return to work for up to 9 months (within a rolling 60-month window) without affecting your SSDI payments. During the TWP, SSA doesn't apply the SGA threshold — instead, any month in which you earn more than $1,110 (2025) counts as a trial work month.
After your TWP ends, you enter the Extended Period of Eligibility, which lasts 36 months. During this window, SSA will review your earnings each month. If you earn above SGA, benefits stop for that month. If you drop below SGA, benefits can restart — without filing a new application.
Once the EPE ends, earning above SGA triggers a formal cessation of benefits. Restarting at that point requires a new application, though Expedited Reinstatement rules may apply if your condition hasn't changed.
The SGA threshold is a fixed number, but how it interacts with your situation depends on several factors:
Someone earning $1,400/month with no IRWEs falls below the 2025 SGA limit and would likely not trigger a cessation review. Someone earning $1,700/month with documented IRWEs of $200/month would have countable earnings of $1,500 — also below the threshold. Someone earning $2,000/month with no deductions is over the limit, and continued SSDI payment would depend entirely on where they are in the TWP or EPE timeline.
None of those outcomes is automatic. SSA reviews the full picture, including documentation you provide.
The 2025 SGA limit of $1,620 (non-blind) and $2,700 (blind) tells you where the line is. Whether your specific earnings, work type, deductible expenses, and position in the SSDI timeline put you above or below that line — and what consequences follow — is a calculation that depends entirely on details SSA would need to evaluate for your case specifically.
