If you were working — or thinking about working — while receiving or applying for SSDI in 2022, one number mattered more than almost any other: the Substantial Gainful Activity (SGA) limit. Understanding what that threshold was, how it was applied, and what it meant for different claimants helps clarify one of the most consequential rules in the entire SSDI program.
Substantial Gainful Activity is the SSA's standard for measuring whether someone is working at a level that disqualifies them from receiving SSDI benefits — or from being found disabled in the first place.
"Substantial" means the work involves significant physical or mental effort. "Gainful" means it's the kind of work done for pay or profit. Together, the SSA uses monthly earnings as a proxy for whether a person is performing SGA.
This isn't a vague judgment call. The SSA applies specific monthly dollar thresholds that adjust annually based on changes in national average wages.
For 2022, the SSA set the SGA limits at:
| Category | Monthly Earnings Limit (2022) |
|---|---|
| Non-blind disability | $1,350/month |
| Statutory blindness | $2,260/month |
These figures applied to gross earnings — what you earned before taxes or deductions — not your take-home pay. If your countable earnings exceeded these amounts, the SSA generally considered you to be engaging in SGA.
The higher threshold for blindness reflects a longstanding statutory distinction in Social Security law, not a medical judgment about severity.
The SGA limit doesn't function the same way throughout the life of a claim. Where you are in the process determines how the threshold is used.
When you first apply for SSDI, the SSA runs your earnings through a five-step sequential evaluation. Step One asks whether you are currently performing SGA. If you are earning above the SGA threshold at the time of your application, the SSA will typically deny your claim at that first step — without ever reviewing your medical records.
This makes the SGA limit a threshold question, not a secondary consideration. Earnings above the limit in 2022 meant $1,350/month or more for most applicants.
Once you're approved and receiving SSDI, the SGA limit continues to apply — but with important work incentives built in.
The Trial Work Period (TWP) allows approved SSDI recipients to test their ability to work for up to nine months (not necessarily consecutive) within a rolling 60-month window. During the trial work period, you can earn any amount without affecting your benefits. In 2022, a trial work month was triggered when earnings exceeded $970/month.
After completing your nine trial work months, you enter the Extended Period of Eligibility (EPE) — a 36-month window during which your benefits can be reinstated in any month your earnings fall below SGA. During this period, the $1,350/month threshold becomes the decisive number again.
If you earn above SGA after the EPE ends, your benefits typically cease and reinstatement requires a new application or expedited reinstatement process.
The SSA doesn't simply look at your paycheck. Certain adjustments can affect how your earnings are counted:
These adjustments mean two people with identical gross earnings could face different SGA determinations depending on their specific work circumstances.
The same $1,350 number played out very differently depending on where someone stood:
The 2022 thresholds — $1,350 for non-blind disability, $2,260 for blindness — were specific to that calendar year. The SSA recalculates SGA limits annually based on the national average wage index. The limit for 2021 was $1,310; it rose in subsequent years. If you're comparing your situation across years, always verify the specific threshold that applied during the relevant period.
The SGA calculation starts with a published number, but what that number actually means for any individual depends on factors the SSA has to evaluate case by case: how your earnings are documented, whether IRWEs apply, what stage of benefits you're in, whether a subsidy arrangement exists with your employer, and how your trial work months have been tracked.
The threshold is public. How it applies to your specific earnings history, work arrangement, and benefit status is something only a full review of your SSA record can resolve.
