If you're receiving SSDI — or applying for it — one of the most practical questions you'll face is how much you're allowed to earn from work. The answer isn't a simple yes or no. It starts with a specific dollar threshold called Substantial Gainful Activity (SGA), and it branches out from there depending on where you are in the SSDI process.
The Social Security Administration uses Substantial Gainful Activity (SGA) as its core earnings benchmark. If you're earning above the SGA level through work, SSA generally considers you capable of supporting yourself — and that affects both your eligibility and your continued benefits.
For 2023, the SGA thresholds are:
| Beneficiary Type | Monthly SGA Limit (2023) |
|---|---|
| Non-blind SSDI recipients | $1,470/month |
| Blind SSDI recipients | $2,460/month |
These figures adjust annually, typically in line with national wage growth. The blind threshold has always been set higher under federal law.
Earning above your applicable SGA limit while receiving SSDI can trigger a review and, potentially, a suspension or termination of benefits. Earning below it generally doesn't put your benefits at risk on its own — though other factors still apply.
Here's something many people miss: SGA matters both when you apply and after you're approved.
At the application stage, SSA uses SGA to determine whether you're even eligible. If you're currently working and earning above $1,470/month (for 2023), your application is likely to be denied at the very first step — before SSA even looks at your medical records. This is called a non-medical denial, and it's one of the most common reasons initial claims are rejected.
After approval, SGA continues to apply. If your earnings exceed the threshold, SSA may find that you're no longer disabled under their definition — which could end your payments.
One important exception to the SGA rule exists for people who are already receiving SSDI benefits: the Trial Work Period (TWP).
During a TWP, you can test your ability to work without immediately losing your benefits, even if your earnings exceed the SGA limit. In 2023, any month in which you earn more than $1,050 counts as a trial work month. You're allowed 9 trial work months within any rolling 60-month window.
Once you've used all 9 trial work months, SSA will review your earnings against the SGA threshold. If you're still earning above SGA after the TWP ends, that's when benefits can stop.
This isn't a loophole — it's a built-in work incentive Congress designed specifically to encourage people to attempt returning to work without the fear of immediately losing benefits.
After the Trial Work Period ends, a 36-month Extended Period of Eligibility (EPE) begins. During these three years, if your earnings drop back below the SGA level in any given month, you can receive SSDI payments for that month without having to file a new application.
This creates a safety net window for people whose work attempts are inconsistent — common among those managing chronic pain, mental health conditions, or episodic disabilities.
Not every dollar you receive is counted the same way. SSA is specifically looking at gross wages from work activity — what you earn, not what you take home after taxes.
A few important nuances:
If you receive Supplemental Security Income (SSI) instead of — or in addition to — SSDI, different income rules apply. SSI has its own earned income exclusions and benefit reduction formulas. The $1,470 SGA figure does not govern SSI eligibility the same way.
People who receive both SSDI and SSI (called dual eligibility) need to understand both sets of rules, which can interact in ways that aren't always intuitive.
The SGA limit is the same for everyone in the same category, but what it means in practice varies considerably:
SSDI recipients are required to report all work activity and earnings to SSA. Failing to report — even unintentionally — can result in an overpayment, which SSA will seek to recover. Overpayments can be significant and can be withheld from future benefit checks.
How and when you report matters. SSA has specific procedures, and keeping documentation of your earnings, pay stubs, and any work expenses is a practical habit worth building from the start.
The 2023 SGA threshold of $1,470 is a fixed number — but what it means for any individual depends on factors that aren't fixed at all: where you are in the application or appeals process, whether you've used any Trial Work Period months, the nature of your employment or self-employment, whether you receive SSI alongside SSDI, and what work expenses might qualify as deductible under SSA's rules.
The program's mechanics are knowable. How those mechanics apply to your specific situation is a different question entirely.
