If you're receiving Social Security Disability Insurance — or thinking about applying — one of the most practical questions you'll face is how much you can earn from work without putting your benefits at risk. The SSA has a specific answer to that, and it's built around a concept called Substantial Gainful Activity, or SGA.
SGA is the earnings threshold the Social Security Administration uses to determine whether someone is working "substantially." If your monthly earnings from work exceed the SGA limit, the SSA may consider you capable of supporting yourself — and that can affect both your eligibility to receive benefits and your continued right to them.
For 2023, the SGA thresholds were:
| Category | Monthly Earnings Limit (2023) |
|---|---|
| Non-blind disability recipients | $1,470/month |
| Statutorily blind recipients | $2,460/month |
These figures adjust each year based on changes in national average wages, so the thresholds for 2024 and beyond will differ. The blind category has always carried a higher limit, which reflects a specific statutory distinction written into the Social Security Act.
The SGA limit isn't just a number to stay under — it functions differently depending on where you are in your SSDI journey.
Before approval: If you're applying and you're currently working above the SGA threshold, the SSA will typically deny your claim at the very first step of the five-step evaluation process. The agency doesn't need to evaluate your medical condition if your earnings already demonstrate you can engage in substantial work.
After approval: Once you're receiving SSDI, the rules shift slightly. The SSA builds in protections designed to encourage beneficiaries to try returning to work without immediately losing benefits. That's where the Trial Work Period (TWP) and the Extended Period of Eligibility (EPE) come in.
The Trial Work Period allows approved SSDI recipients to test their ability to work for up to nine months (not necessarily consecutive) within a rolling 60-month window — without losing benefits, regardless of how much they earn during those months.
In 2023, a month counted as a TWP month if your earnings exceeded $1,050. Once you've used all nine TWP months, the SSA reviews whether you've been earning above SGA.
After your TWP ends, you enter a 36-month Extended Period of Eligibility. During this window, any month your earnings fall below SGA, you can receive your full SSDI benefit. Any month you earn above SGA, benefits are suspended — but not permanently terminated right away. This gives recipients a meaningful safety net if work attempts don't go as planned.
Not every dollar that comes in is treated the same way. The SSA generally looks at gross wages from employment or net earnings from self-employment when calculating SGA. However, certain deductions can reduce the countable amount:
The distinction between what counts and what can be excluded matters significantly — and it's one reason two people with the same paycheck can face very different SGA determinations.
The 2023 earnings limit doesn't apply the same way across all claimants and recipients. Several variables shape how these rules play out: 🔍
Applicants still waiting for a decision face strict SGA scrutiny. Any earnings above the monthly limit during the application period can be grounds for denial before the medical review even begins.
Newly approved recipients who want to re-enter the workforce have the most flexibility, particularly if they haven't yet used their Trial Work Period months.
Long-term recipients who completed their TWP years ago are in a different position — they're operating inside the Extended Period of Eligibility or may have already exhausted it, which changes how the SSA treats any work activity.
Self-employed individuals face an especially complex calculation. The SSA doesn't just look at income — it can also consider the time, energy, and skill you put into a business, even if you're not drawing a high salary from it.
Recipients with a blindness designation operate under the higher $2,460 threshold and a distinct set of evaluation rules under the Social Security Act.
The 2023 SGA limit of $1,470 per month is a fixed, public figure. What it means for any particular person — whether earnings push them over the threshold, whether deductions bring them back under it, whether the Trial Work Period still applies, or whether benefits would be suspended versus terminated — depends entirely on the specifics of their work activity, benefit history, and how the SSA has documented their case.
Two recipients earning the same gross wages in the same month can land in very different places. The threshold is where the program's logic starts. Your own situation is where the actual answer lives.
