If you're receiving SSDI benefits — or thinking about applying — one question comes up constantly: how much can I earn each month without losing my benefits? The answer hinges on a specific SSA threshold called Substantial Gainful Activity (SGA), and understanding how it works is essential before you accept any paycheck.
SSDI is not a needs-based program like SSI. It doesn't count your savings or your spouse's income. But it does care — intensely — about whether you're working and how much you're earning from that work.
The SSA uses the SGA threshold to decide two things:
SGA is a monthly gross earnings figure. If you earn above it from work, the SSA may determine you are not disabled under their definition — regardless of your medical condition.
For 2025, the SGA limit is $1,620/month for non-blind individuals and $2,700/month for those who are statutorily blind. These figures adjust annually, typically each January, based on changes to the national average wage index. The 2026 figures have not been officially confirmed as of this writing — always verify the current thresholds directly at SSA.gov, since they change year to year.
The SGA limit doesn't work the same way at every stage. Your relationship to this number shifts depending on whether you're applying, in your trial work period, or past it.
The SSA evaluates your current earnings as part of the five-step disability determination process. If you're earning above SGA in the month you apply — or during the review period — your claim is typically denied at Step 1, before the SSA even looks at your medical records.
This is a hard stop. The medical evidence, your work history, your age, and your RFC (Residual Functional Capacity) are all irrelevant if the SSA decides you're engaging in SGA.
Once you're receiving benefits, the SGA rules work differently. The SSA builds in structured protections called work incentives that allow you to test your ability to return to work without immediately losing benefits.
The Trial Work Period (TWP) gives you nine months (not necessarily consecutive) during a rolling 60-month window to work at any income level without affecting your benefits. In 2025, any month in which you earn more than $1,110 counts as a trial work month. That figure also adjusts annually.
After you've used all 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. If you earn above SGA during the EPE, your benefits stop for that month. If you drop below SGA, they resume.
Once the EPE ends, earning above SGA means your benefits terminate and you'd need to reapply or request Expedited Reinstatement if your earnings drop again within five years.
🔍 Not all money you receive is treated the same way under the SGA calculation.
The SSA focuses specifically on countable earned income from work — wages, self-employment earnings, and certain in-kind compensation. Several deductions can reduce your countable earnings below SGA even if your gross paycheck appears to exceed the limit:
Self-employment is evaluated differently than wage employment. The SSA applies a more complex analysis to determine what you actually contributed to the business, which can significantly change how your earnings are counted.
| Situation | How SGA Applies |
|---|---|
| Applying for SSDI, earning above SGA | Likely denied at Step 1 without medical review |
| Approved, in Trial Work Period | Can earn any amount; benefits continue |
| Approved, past TWP, earning above SGA | Benefits suspended for that month |
| Has significant IRWEs | Countable income may fall below SGA even with higher gross pay |
| Self-employed | Earnings evaluated by services rendered, not gross profit alone |
| Statutorily blind | Higher SGA threshold applies ($2,700 in 2025) |
The SGA threshold is the same for everyone in the same category — but how it applies to your situation depends on a web of individual factors:
A person with high out-of-pocket medication costs required to maintain employment may have countable income well below SGA even if their paycheck appears to exceed the threshold. Someone who just crossed the nine-month mark in their trial work period faces an entirely different calculation than someone who used their TWP years ago.
The SGA number is public and consistent. What it means for your benefits — and whether you're approaching a risk point — is something only your full employment and benefit history can answer.
