If you're receiving SSDI — or applying for it — the term Substantial Gainful Activity (SGA) comes up constantly. For 2025, the SGA threshold is one of the most searched figures in the program, and for good reason: it's the number SSA uses to decide whether your work activity is compatible with receiving benefits.
Here's what SGA actually means, how the 2025 amount works in practice, and why the same dollar figure can have very different implications depending on where someone is in the SSDI process.
Substantial Gainful Activity is SSA's standard for measuring whether a person is working at a level considered significant enough to disqualify them from SSDI benefits. It's not a judgment about effort or intention — it's a monthly earnings threshold applied consistently across the program.
SSA adjusts SGA annually based on changes in the national average wage index. That means the number you read in 2023 may already be outdated.
For 2025, SSA set the SGA threshold at:
| Category | Monthly SGA Amount (2025) |
|---|---|
| Non-blind disability | $1,620/month |
| Statutorily blind (Title II) | $2,700/month |
These figures apply to gross earnings, not take-home pay. SSA looks at what you earn before taxes and deductions, though certain work-related expenses can sometimes be excluded through what SSA calls Impairment-Related Work Expenses (IRWEs).
The higher threshold for statutorily blind individuals reflects a longstanding statutory distinction in the Social Security Act. If your SSDI approval is based on blindness as defined under SSA rules, a different limit applies to you.
SGA isn't a single gatepost. It operates differently depending on where you are in the SSDI process.
When you apply for SSDI, SSA first checks whether you're engaging in SGA at the time of application. If your earnings exceed the threshold, SSA will typically deny the claim at Step 1 of the five-step sequential evaluation — before ever reviewing your medical records.
This is why many people reduce or stop working before or shortly after applying. If you're earning above SGA when SSA processes your claim, your medical evidence may never be fully evaluated.
Once approved, SSDI beneficiaries aren't permanently locked out of working. SSA provides structured work incentives designed to encourage a return to employment without immediately cutting off benefits.
The Trial Work Period (TWP) lets you test your ability to work for up to 9 months (not necessarily consecutive) within a rolling 60-month window. During the TWP, you can earn any amount without losing benefits — SGA doesn't apply yet.
In 2025, a month counts toward your Trial Work Period if you earn more than $1,110/month (this threshold also adjusts annually and is separate from SGA).
Once you've used your 9 Trial Work Period months, SSA begins evaluating your earnings against the SGA threshold. If you earn above $1,620/month (for non-blind recipients in 2025) during what's called the Extended Period of Eligibility (EPE), SSA can suspend or terminate your cash benefits.
The EPE lasts 36 months after the Trial Work Period ends. During this window, benefits can be reinstated quickly in months when your earnings fall below SGA — without filing a new application.
Not every dollar of income runs through the SGA calculation the same way. SSA focuses specifically on wages from work activity and net earnings from self-employment. Passive income — such as investment returns, rental income, or Social Security itself — does not count toward SGA.
For self-employed individuals, SSA may also consider time spent and services performed, not just dollar amounts, when evaluating SGA. The calculation becomes more involved and depends on the nature of the business and the individual's role.
Impairment-Related Work Expenses can reduce countable earnings. If you pay out of pocket for items or services that make it possible for you to work — specialized transportation, certain medical equipment, medications — SSA may deduct those costs before comparing your earnings to the SGA threshold.
Two people earning $1,650/month in 2025 — just above the SGA threshold — can have completely different outcomes:
The number itself is uniform. Its effect depends entirely on your benefit status, the timing, and the specifics of your work situation.
SSA's SGA threshold for 2025 is a defined, publicly available number — and understanding it is straightforward. What isn't straightforward is how it intersects with your particular approval date, your work history since approval, any impairment-related expenses you might claim, and whether you've entered or exited the Trial Work Period.
Those details don't live in a chart. They live in your SSA file, your pay stubs, and the timeline of your own case. The threshold is the same for everyone. What it means for your benefits is anything but.
