The trial work threshold is not the same thing as the substantial gainful activity limit of $1,690, and confusing the two is the fastest way to lose a benefit that the rules were designed to protect.
The Social Security Administration (SSA) counts any month in which a beneficiary on Social Security Disability Insurance (SSDI) earns more than $1,210 in 2026 as a trial work month. Nine such months inside a rolling 60-month window exhaust the trial work period, and during every one of those nine months the SSDI payment continues in full, no matter how high the earnings go. The average SSDI disabled-worker benefit was $1,635.27 a month in SSA’s July 2026 data, and about 6.99 million disabled workers are covered by these rules.
What a trial work month is, and what it is not
The trial work period exists so that someone receiving SSDI can test whether they can return to work without gambling their entire benefit on the attempt. The $1,210 figure is only a counter. Crossing it does not reduce the check, does not trigger a review of the medical condition and does not by itself end eligibility. It simply marks the month as used.
Two details decide how long a trial work period actually lasts. The nine months do not have to be consecutive, and the window that holds them rolls: SSA looks back across the previous 60 months to see how many service months have already been counted. For someone working intermittently, the trial work period can therefore stretch across years. For someone who returns to steady full-time work, it can be gone in nine.
$1,210 or $1,690: the distinction that matters
These are two different thresholds doing two different jobs, and readers routinely merge them. Substantial gainful activity (SGA) in 2026 is $1,690 a month for non-blind beneficiaries and $2,830 for blind beneficiaries. It is the level of earnings SSA treats as evidence that a person is no longer disabled for program purposes.
- $1,210 counts a trial work month. Benefits continue regardless.
- $1,690 (or $2,830 if blind) is the SGA level. It matters only after the trial work period is over.
By contrast with the trial work threshold, earnings above SGA carry consequences, but not immediately and not permanently. That is the point of the stage that follows.
The 36 months after the nine
When the ninth service month is used, the extended period of eligibility begins and runs for 36 consecutive months, according to SSA’s fact sheet on the trial work period. Inside that window the arithmetic changes month by month: in any month earnings fall below the SGA level, the benefit is payable; in any month they exceed it, it is not. The entitlement itself is not cancelled, which means a bad month at work does not require a new application.
Benefits stop for good only after the extended period ends, if earnings at that point are above SGA. That is the moment the entitlement terminates.
Expedited reinstatement, the safety net after termination
Even termination is not final. Under expedited reinstatement, someone whose SSDI ended because of work can ask for it back without filing a fresh claim, provided the request comes within 60 months of the earlier termination and the same medical condition prevents substantial work. While SSA reviews the request, up to six months of provisional benefits can be paid.
It is worth remembering one further piece of the structure: at full retirement age, which is 67 for anyone born in 1960 or later, SSDI converts automatically into a retirement benefit of the same dollar amount, and work rules of this kind no longer apply.
The practical takeaway is procedural rather than financial. Every month worked while on SSDI should be reported to SSA with the gross amount, because the agency’s count of service months, not the beneficiary’s, is the one that determines where in the sequence a person stands.
