If you're receiving SSDI — or applying for it — one of the most important numbers to understand is the income limit. Earn too much, and the Social Security Administration may determine you're no longer disabled. But the rules aren't as simple as a single cutoff. Multiple thresholds apply depending on where you are in your SSDI journey, whether you have a visual impairment, and how long you've been receiving benefits.
The SSA doesn't measure disability purely by diagnosis. It also measures what you can do — specifically, whether you're engaged in Substantial Gainful Activity (SGA). SGA is the SSA's term for work that produces income above a defined monthly threshold.
For 2025, the SGA limits are:
| Category | Monthly SGA Limit (2025) |
|---|---|
| Non-blind SSDI recipients | $1,620/month |
| Statutorily blind SSDI recipients | $2,700/month |
These figures adjust annually based on national wage trends, so it's worth confirming current figures directly with the SSA each year.
If you're applying for SSDI and currently earning above the SGA threshold, the SSA will typically deny your claim at the very first step — before even reviewing your medical records. This is why SGA isn't just a rule for existing recipients; it affects the outcome of initial applications too.
At the initial application stage, the SSA checks whether your current earnings exceed SGA. If they do, the claim is generally denied outright. This applies regardless of how serious your medical condition is. A claimant with a severe impairment who earns $1,700/month in 2025 would typically not advance further in the review process.
After approval, the income rules become more nuanced. SSDI includes built-in work incentives designed to let recipients test their ability to work without immediately losing benefits.
Trial Work Period (TWP): For 2025, any month in which you earn more than $1,110 counts as a Trial Work Period month. You're allowed nine of these months within a rolling 60-month window. During the TWP, you keep full SSDI benefits regardless of how much you earn — the SGA limit doesn't apply yet.
Extended Period of Eligibility (EPE): After using all nine Trial Work Period months, a 36-month window begins. During this period, your benefits are suspended in any month you earn above SGA — but not terminated. If your earnings drop below SGA again, benefits can be reinstated without a new application.
Benefit Termination: Only after the EPE ends does consistent earnings above SGA lead to formal termination of SSDI benefits.
This staged structure means the income limit that matters to you depends heavily on where you are in this timeline.
Not all money received counts equally. The SSA focuses primarily on gross wages from work and net earnings from self-employment. Passive income — such as investment returns, rental income, or inherited money — generally does not count toward SGA.
However, certain work-related factors can affect how the SSA calculates your countable earnings:
These deductions don't apply automatically. They require documentation and SSA review.
The income rules described above apply to SSDI, which is funded through work history and payroll taxes. SSI (Supplemental Security Income) operates on an entirely different income formula — one that also counts unearned income and assets.
If you receive both SSDI and SSI simultaneously (known as "concurrent benefits"), both sets of rules apply in parallel, which creates a more complex income picture. Your SSDI payment itself counts as income under SSI calculations, which can reduce or eliminate the SSI portion of your benefit.
Two SSDI recipients earning the same monthly amount can face very different outcomes depending on:
Someone six months into their Trial Work Period faces completely different rules than someone two years past it. Someone who is self-employed faces a different calculation methodology than a salaried employee.
The 2025 SGA threshold of $1,620 is a precise number — but it's only one data point in a larger equation. Whether that limit affects your benefits right now, in six months, or not at all depends on your work history with the SSA, how your earnings are categorized, what expenses qualify for deduction, and how the SSA has documented your case to date.
The threshold is the same for everyone. How it applies is not.
