If you're receiving SSDI benefits — or applying for them — the term Substantial Gainful Activity (SGA) will shape nearly every work-related decision you make. For 2025, the SSA has updated these thresholds, and understanding exactly what they mean (and what they don't) is essential before you earn a single dollar from work.
Substantial Gainful Activity is the SSA's standard for measuring whether someone is working at a level that, by definition, disqualifies them from receiving SSDI benefits. The SSA uses two criteria to define "substantial" and "gainful": the work involves significant physical or mental activity, and it's performed for pay or profit.
SGA isn't just a technicality. It's the first filter the SSA applies when reviewing a new SSDI application and a continuous monitoring tool for people already receiving benefits. Exceed it, and the SSA may determine you're not disabled under their rules — regardless of your medical condition.
The SSA adjusts SGA limits annually based on changes in the national average wage index. For 2025, the thresholds are:
| Category | Monthly SGA Limit (2025) |
|---|---|
| Non-blind disability | $1,620/month |
| Blind disability (statutory blindness) | $2,700/month |
These figures represent gross earnings, not take-home pay. The SSA looks at what you earn before taxes and deductions — with some important exceptions discussed below.
The blind threshold is higher because Congress established a separate, more generous standard for individuals meeting the SSA's definition of statutory blindness.
When you apply for SSDI, the SSA looks at whether you are currently engaging in SGA. If your earnings in the month you apply — or in recent months — exceed the SGA threshold, your application can be denied at Step 1 of the five-step sequential evaluation, before your medical records are even reviewed.
This makes SGA one of the fastest disqualifying factors in the SSDI process.
Once approved, SSDI recipients don't lose benefits the moment they start working. The SSA provides structured work incentives to encourage a return to employment without immediate risk.
The Trial Work Period (TWP) allows you to test your ability to work for up to 9 months (within a rolling 60-month window) without it affecting your benefits — regardless of how much you earn during those months. In 2025, any month in which you earn more than $1,110 counts as a trial work month.
After using all 9 trial work months, the SSA evaluates whether you're performing SGA. If you are, your Extended Period of Eligibility (EPE) begins — a 36-month window during which your benefits can be reinstated in any month your earnings fall below SGA, without a new application.
The SSA periodically reviews all SSDI cases. During a Continuing Disability Review (CDR), evidence of SGA-level earnings can trigger scrutiny of your case — even if the earnings are recent and temporary.
Not every dollar you earn counts toward the SGA calculation. The SSA allows Impairment-Related Work Expenses (IRWEs) to be deducted from gross earnings before making the SGA comparison. These are costs directly related to your disability that you must pay in order to work — such as specialized transportation, certain medications, or assistive equipment.
This deduction can make a meaningful difference for people whose work-related costs are significant. The key word is "impairment-related" — general living expenses don't qualify.
The SSA may also consider subsidies (situations where an employer pays you more than the actual value of your work, such as in a supported employment arrangement) when determining the real countable value of your earnings.
The published threshold is straightforward. How it applies to any individual is not. Several variables affect the outcome:
Crossing the SGA line doesn't always mean an immediate benefit termination — the sequence matters. 💡
Each of these outcomes depends on where you are in the benefit timeline.
The 2025 SGA limits — $1,620 for most recipients, $2,700 for the statutorily blind — are fixed numbers set by the SSA. But whether your earnings actually exceed SGA in a way that affects your benefits depends on the type of work you do, how you're paid, what expenses can be deducted, and exactly where you stand in the SSDI benefit lifecycle. The threshold tells you where the line is. Your earnings history, work arrangement, and benefit status determine which side of it you're on.
