If you're receiving SSDI — or applying for it — understanding the program's income limits is one of the most practical things you can do. These limits don't just affect whether you qualify. They shape what happens when you try to return to work, take on part-time hours, or earn money from any source while your benefits are active.
SSDI is built around one central income test: Substantial Gainful Activity, or SGA. The SSA uses SGA to determine whether you're working at a level that suggests you aren't disabled under the program's definition.
In 2025, the SGA threshold is:
| Category | Monthly Earnings Limit |
|---|---|
| Non-blind disability | $1,620/month |
| Statutorily blind | $2,700/month |
These figures adjust annually based on national wage trends — what applies in 2025 may shift in 2026.
If your countable earned income exceeds the SGA limit, the SSA can find that you're not disabled, which affects both initial applications and ongoing eligibility for people already receiving benefits.
SGA applies to earned income — wages from a job or net earnings from self-employment. It does not apply to:
The SSA also allows certain deductions before applying the SGA test. Impairment-related work expenses (IRWEs) — costs you pay out of pocket because of your disability that allow you to work — can be subtracted from your gross earnings before the SGA calculation. This matters: someone earning $1,800/month but paying $250/month in disability-related transportation or equipment costs may fall below the SGA threshold after deductions.
Already receiving SSDI and considering a return to work? The program includes built-in protections.
The Trial Work Period (TWP) allows you to 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.
Once you've used all 9 trial work months, the SSA evaluates whether your earnings exceed SGA. If they do, your benefits can stop — but not immediately.
After the Trial Work Period ends, you enter a 36-month Extended Period of Eligibility (EPE). During this window, you can receive benefits for any month your earnings fall below the SGA threshold. If you earn above SGA, benefits stop for that month — but they can be reinstated without a new application if your earnings drop again.
This structure gives recipients a longer runway than most people realize. It's not a single cliff — it's a graduated transition.
If your earnings consistently exceed SGA after your Trial Work Period, the SSA will issue a cessation determination — a formal finding that your disability is no longer the reason you can't work. Benefits stop, typically after a grace period of three benefit months.
At that point, you can appeal. If your disability worsens and you need to reapply within five years, you may be eligible for Expedited Reinstatement (EXR), which allows faster restoration of benefits without a full new application.
SSDI and SSI are separate programs with different income rules. This distinction trips people up constantly.
| Feature | SSDI | SSI |
|---|---|---|
| Income test | SGA (earned income) | Countable income from all sources |
| Asset limits | None | $2,000 individual / $3,000 couple |
| Benefit basis | Work history / credits | Financial need |
| Unearned income impact | Generally no effect | Reduces monthly benefit dollar-for-dollar (with exclusions) |
If you receive both SSDI and SSI (called dual eligibility), both sets of rules apply simultaneously. Your SSDI payment counts as unearned income for SSI purposes, which is why many dual recipients receive a reduced SSI supplement rather than the full SSI benefit.
The SGA number is the same for everyone at a given threshold — but how it applies to any specific person depends on variables the SSA evaluates case by case:
The 2025 SGA limit is a public number. What it means for your specific case — how the SSA will treat your particular earnings history, your impairment-related expenses, your trial work month count, or the interaction between your SSDI and any other income — is where the rule stops being simple.
Someone earning $1,650/month with $200 in IRWEs sits in a different position than someone earning the same gross amount with no deductible expenses. Someone in month six of their Trial Work Period operates under entirely different rules than someone whose EPE expired two years ago.
The framework is knowable. Where you stand inside it is the piece only your specific record can answer.
