If you're receiving Social Security Disability Insurance — or thinking about working while on SSDI — one number matters more than almost any other: the Substantial Gainful Activity (SGA) threshold. This is the monthly earnings limit the Social Security Administration uses to decide whether your work activity is significant enough to affect your benefits.
Here's what that limit looks like in 2025, and what it actually means in practice.
For 2025, the SGA threshold is $1,620 per month for non-blind SSDI recipients. For individuals who are statutorily blind, the limit is higher — $2,700 per month in 2025.
These figures adjust each year based on changes in average wages, so they're worth checking annually.
| Category | 2025 Monthly SGA Limit |
|---|---|
| Non-blind disability | $1,620 |
| Statutory blindness | $2,700 |
If your countable earnings exceed the applicable threshold, SSA may determine that you are engaging in substantial gainful activity — which can put your SSDI eligibility at risk.
The SGA limit isn't simply your gross paycheck. SSA calculates countable earnings after subtracting certain work-related expenses, particularly Impairment-Related Work Expenses (IRWEs) — costs you pay out of pocket that are necessary for you to work because of your disability.
Examples of IRWEs might include specialized transportation, certain medications, or assistive equipment required on the job. Subtracting these expenses from your gross earnings can bring your countable income below the SGA line even if your gross pay exceeds it.
This distinction matters. Someone earning $1,800 per month gross might have countable earnings of $1,400 after legitimate IRWEs — keeping them under the 2025 threshold.
The SGA limit doesn't operate the same way at every stage of your SSDI case. 🗓️
Before approval: SSA uses the SGA threshold to evaluate whether you were working at the time you applied or during your alleged disability period. If you're earning above SGA when you apply, SSA will typically deny the claim at the very first step of the five-step sequential evaluation — regardless of your medical condition.
After approval: Once you're receiving SSDI, the SGA limit governs what happens if you return to work. But SSA builds in structured protections before it counts your earnings against you.
SSDI includes a series of work incentive programs designed to encourage beneficiaries to test their ability to work without immediately losing benefits. Understanding these is essential before assuming that any earnings above $1,620 will end your SSDI.
Trial Work Period (TWP) The trial work period allows SSDI recipients to test their ability to work for up to 9 months (not necessarily consecutive) within a rolling 60-month window. During the TWP, you receive full SSDI benefits regardless of how much you earn — as long as you report your work activity to SSA.
In 2025, a month counts as a trial work month if you earn more than $1,110.
Extended Period of Eligibility (EPE) After your trial work period ends, you enter a 36-month extended period of eligibility. During this window, SSA evaluates your earnings each month against the SGA limit. Months when your countable earnings fall below $1,620 are "benefit months" — you receive your full payment. Months above SGA are "cessation months."
This structure gives beneficiaries meaningful flexibility during the transition back to work.
Ticket to Work The Ticket to Work program is a free SSA initiative that connects SSDI recipients with employment support services. Participating in the program can also provide some protection from continuing disability reviews while you're actively working toward employment goals.
The SGA limit is specifically about earned income from work. It does not apply to:
SSDI is not means-tested the way SSI (Supplemental Security Income) is. SSI has strict asset and total income limits that apply broadly. SSDI's income rules focus narrowly on work activity. These two programs are frequently confused, and that confusion can lead people to misread which rules apply to them.
Whatever you earn, SSA requires SSDI recipients to report all work activity promptly. Failing to report wages — even if your countable earnings stay below SGA — can result in overpayments that SSA will eventually seek to recover. Overpayment notices are one of the most common and disruptive problems SSDI recipients face, and most stem from delayed or missing wage reports.
SSA offers several ways to report: by phone, in person at your local field office, through your my Social Security online account, or through the SSA mobile app.
How the SGA limit actually affects you depends on variables that aren't visible in any single number:
Two people earning identical wages in 2025 can have entirely different outcomes depending on where they stand in the trial work period, how their earnings are documented, and whether IRWEs apply.
The $1,620 figure is the starting point. Where it leads for any individual recipient depends on the full picture of their work history, benefit status, and documented expenses — none of which appear in the threshold alone.
