If you're receiving SSDI — or applying for it — understanding how much you can earn from work is one of the most practical things you can know. The Social Security Administration doesn't expect every SSDI recipient to never work again. But it does draw a clear line between work that's considered minor and work that suggests you're no longer disabled. That line has a name: Substantial Gainful Activity, or SGA.
The SGA threshold is the monthly earnings amount the SSA uses to evaluate whether your work activity is significant enough to affect your disability status. If you earn above this amount, the SSA may determine that you are capable of substantial work — which can affect both your application and your ongoing benefits.
For 2025, the SGA limit is $1,620 per month for non-blind recipients. For individuals who are statutorily blind, the limit is higher — $2,700 per month in 2025. These figures adjust annually based on changes in average wages, so the numbers you see in older articles may already be outdated.
It's worth repeating: these are gross earnings thresholds, not take-home pay. The SSA looks at what you earn before taxes and most deductions.
The SGA limit doesn't work the same way throughout your SSDI journey. Where you are in the process matters significantly.
If you're applying for SSDI and currently working, the SSA will check your earnings against the SGA threshold right away. Earning above $1,620/month in 2025 while applying will typically result in a denial at the initial review stage — before your medical records are even fully evaluated. The SSA treats SGA as a threshold question: if you're earning above it, the process generally stops there.
Once you're receiving SSDI benefits, the rules become more nuanced. The SSA recognizes that some people want to test their ability to return to work, and it has built-in protections to support that.
The Trial Work Period (TWP) allows approved SSDI recipients to test working without immediately losing benefits. In 2025, any month in which you earn more than $1,110 counts as a trial work month. You can use up to 9 trial work months (not necessarily consecutive) within a rolling 60-month window. During this period, you generally continue receiving your full SSDI payment regardless of earnings.
The Extended Period of Eligibility (EPE) follows the TWP. It covers the 36 months after your trial work period ends. During the EPE, you receive benefits in any month your earnings fall below SGA ($1,620 in 2025) and benefits are suspended in months your earnings exceed it. You don't need to reapply if your earnings drop again.
| Stage | Earnings Threshold (2025) | What Happens |
|---|---|---|
| Application | $1,620/month (SGA) | Earning above this typically triggers denial |
| Trial Work Period | $1,110/month (TWP trigger) | Benefits continue; months count toward 9-month TWP |
| Extended Period of Eligibility | $1,620/month (SGA) | Benefits paid in low-earning months, suspended above SGA |
| After EPE Ends | $1,620/month (SGA) | Exceeding SGA may require new application to restart benefits |
Not every dollar you receive is counted the same way. The SSA applies something called Impairment-Related Work Expenses (IRWEs) — costs directly tied to your disability that allow you to work (medications, specialized equipment, certain transportation) can sometimes be deducted from your gross earnings before the SGA comparison is made.
Self-employment income is evaluated differently than wages. The SSA looks at net earnings, business expenses, and the nature of your involvement in the business — not just a paycheck stub.
What does not count: Investment income, rental income, Social Security payments themselves, and most passive income sources are not counted toward the SGA limit. The earnings limit is specifically about income from work activity.
The SGA threshold is a fixed number, but how it applies to your situation depends on several factors:
Someone newly applying who picks up part-time work earning $900/month faces a different situation than an established SSDI recipient in month six of a trial work period earning $2,000/month. A self-employed person managing their own business hours faces a different calculation than a salaried employee. Someone who became blind before age 55 has access to a different SGA threshold entirely.
Two people earning the same gross amount can land in very different places depending on their IRWEs, their TWP status, the nature of their work, and what the SSA determines counts as "countable" earnings.
The 2025 SGA limit of $1,620 per month is a concrete number — a genuine starting point. But whether that number triggers a denial, a benefit suspension, or has no effect at all depends entirely on the details of your individual situation: when you were approved, how many trial work months you've used, how your income is structured, and whether any deductions apply.
The rules are consistent. How they interact with any one person's circumstances is not.
