If you're receiving SSDI — or thinking about working while on it — the Substantial Gainful Activity (SGA) limit is one of the most important numbers to know. Cross it, and your benefits could stop. Stay under it, and you may be able to earn income while remaining eligible. Here's how SGA works in 2025, what changed, and why the same number doesn't affect every SSDI recipient the same way.
Substantial Gainful Activity is the earnings threshold the Social Security Administration uses to determine whether someone is working at a level that disqualifies them from SSDI. The program is designed for people who can't work because of a disabling condition — so if you're earning above a certain amount, SSA treats that as evidence you can work, regardless of your medical situation.
SGA applies at two key moments:
The SGA threshold adjusts annually based on changes in the national average wage index. For 2025, the amounts are:
| Claimant Category | Monthly SGA Limit (2025) |
|---|---|
| Non-blind SSDI recipients | $1,620/month |
| Blind SSDI recipients | $2,700/month |
The higher limit for blind recipients is set by statute and has historically been more generous than the standard threshold.
These figures represent gross earnings — your pay before taxes or deductions. SSA does allow certain work-related expenses to be deducted in some cases (more on that below), but the starting point is always your gross monthly income from work.
SSA doesn't just look at your paycheck. When evaluating SGA, they consider:
This means two people earning the same gross amount could have very different countable earnings in SSA's eyes.
One important nuance: the SGA limit doesn't apply during your Trial Work Period (TWP). 🔍
After you're approved for SSDI, you're entitled to a nine-month Trial Work Period (the months don't have to be consecutive) during which you can test your ability to work and still receive full benefits — regardless of how much you earn. In 2025, any month in which you earn more than $1,110 counts as a Trial Work Period month.
Once you've used all nine TWP months, you enter the Extended Period of Eligibility (EPE) — a 36-month window during which your benefits are suspended (not terminated) in any month your earnings exceed SGA, and reinstated in months they don't. After the EPE ends, consistently earning above SGA leads to termination.
This structure matters a great deal to someone re-entering the workforce. Where you are in the TWP/EPE timeline shapes how the 2025 SGA threshold actually affects your case.
The same $1,620 threshold operates differently depending on where you are in the SSDI process:
At the application stage: Earning above SGA is a hard stop. SSA evaluates the five-step sequential evaluation, and step one asks whether you're currently doing SGA. If yes, the claim is denied — no medical review happens at all. This catches a lot of applicants off guard.
After approval: The threshold triggers what's called a Continuing Disability Review (CDR) related to work activity. SSA monitors your earnings through employer wage reports and tax records. A spike above SGA — especially after your TWP is used — prompts SSA to evaluate whether your benefits should continue.
During the appeals process: If you're at reconsideration, an ALJ hearing, or the Appeals Council stage, and you begin working above SGA, it complicates your case significantly. It doesn't automatically end an appeal, but it becomes a factor SSA weighs.
The 2025 SGA amount is a fixed number — but how it applies to any individual depends on factors that vary widely:
Someone newly approved with no TWP months used faces a very different SGA calculation than someone who used their trial months two years ago and is now in the EPE. The number is the same. What it means for each person is not.
