If you're receiving SSDI — or applying for it — one of the most practical questions you'll face is how much income you're allowed to earn. Work too much, and you risk losing your benefits. But the rules aren't as simple as a single cutoff number. Understanding how income limits interact with your benefit status, your work history, and where you are in the SSDI process makes a real difference.
SSDI is designed for people who cannot engage in Substantial Gainful Activity (SGA) due to a qualifying disability. SGA is the SSA's benchmark for whether your work activity is significant enough to suggest you're not disabled under their definition.
In 2025, the monthly SGA threshold is:
| Category | Monthly SGA Limit (2025) |
|---|---|
| Non-blind disability | $1,620/month |
| Statutory blindness | $2,700/month |
These figures adjust annually based on changes in average wages. If your countable earnings consistently exceed the SGA limit, the SSA may determine you're no longer disabled — regardless of your medical condition.
Countable earnings are generally your gross wages minus certain impairment-related work expenses (IRWEs), which the SSA allows you to deduct before applying the SGA test.
Where you are in the SSDI process shapes how income limits apply to you.
If you're still waiting on an initial decision or going through reconsideration or an ALJ hearing, the SSA will look at whether your earnings exceed SGA at any point during the period you're claiming disability. Earning above the SGA threshold during your alleged onset period can create serious problems for your claim — it signals to the SSA that you may be capable of substantial work.
Once you're approved and receiving SSDI, the rules become more nuanced. The SSA encourages beneficiaries to attempt returning to work through its Trial Work Period (TWP).
During the TWP, you can test your ability to work for up to 9 months (not necessarily consecutive) within a rolling 60-month window without losing your benefits — regardless of how much you earn. In 2025, any month in which you earn more than $1,110 counts as a trial work month.
After completing your 9 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 the SGA threshold.
| Phase | What It Means |
|---|---|
| Trial Work Period | Up to 9 months of unlimited earnings without losing benefits |
| Extended Period of Eligibility | 36-month safety net after TWP ends |
| Post-EPE | Benefits stop if earnings exceed SGA; reinstatement requires new application or Expedited Reinstatement |
Not all income triggers the SGA test in the same way. The SSA focuses primarily on earned income — wages from work or net self-employment profit. Passive income such as investments, rental income, or Social Security benefits themselves does not count toward SGA.
Key deductions that can reduce your countable earnings:
It's worth clarifying a common source of confusion. SSDI and SSI (Supplemental Security Income) are two separate programs with different income rules.
If you receive both programs simultaneously (dual eligibility), both sets of rules apply — and the interaction between them requires careful tracking.
The SGA thresholds are the floor of the analysis, not the ceiling of the conversation. Several variables determine how income rules actually play out for any given person:
Two SSDI recipients earning $1,500/month can face completely different outcomes. One — still in their Trial Work Period — keeps full benefits without interruption. Another — post-EPE, earning the same amount but above SGA — could face benefit termination. A third, with documented IRWEs that reduce countable earnings below $1,620, may not trigger SGA at all. 💡
The dollar thresholds in 2025 are publicly available and apply the same way on paper. But the calculation that follows — what counts, what gets deducted, what phase of benefits you're in — is built from details that only apply to you.
That's the part the SGA table can't answer.
