If you’re applying for Social Security Disability Insurance (SSDI) or Supplemental Security Income (SSI), one of the most confusing questions is whether working will hurt your case. The short answer is: it can, but not always in the same way, and not for every person.
A lot depends on how much you earn, how long the work lasts, what duties you actually perform, whether you receive accommodations, and where your case is in the process. Social Security looks at more than a paycheck. It also looks at whether the work suggests an ability to perform substantial gainful activity, often shortened to SGA. The agency’s current 2026 SGA amount for most disabled workers is $1,690 per month, and $2,830 per month for blind SSDI claimants; the blind SGA amount does not apply the same way in initial SSI eligibility cases for blindness, which is one reason SSI and SSDI often get mixed together online (SSA SGA overview).
In this post you’ll learn what working can mean during a pending disability claim, how SSDI and SSI differ, why short work attempts are sometimes treated differently, and what details often matter most when an attorney reviews the file. If you want a deeper breakdown of the work rules themselves, our guide on when work activity starts affecting disability claims gives more context on SGA, failed work attempts, and appeal risk.

At the center of both SSDI and SSI disability claims is a basic legal issue: whether a person can perform work at a level Social Security considers substantial. Under Social Security’s rules, a person generally is not found disabled if they are currently engaging in SGA when filing or while the claim is being evaluated (SSA Handbook).
That is where the tension comes from. Many people try to work because they are under financial pressure, trying to keep insurance, testing whether they can function again, or holding onto a job with help from coworkers, family, or special accommodations. None of that is unusual. In fact, Social Security reported that more than 1.8 million people applied for disability benefits in fiscal year 2023, which helps show how often disability claims and employment questions overlap in real life (SSA blog).
But even limited work can become evidence in several different ways:
In general terms, the issue is rarely just “Did you work?” The more important question is often “What did the work actually show?”
Social Security often focuses on paid work or work done for profit. If you are earning wages, working self-employment hours, or doing duties that resemble competitive employment, the agency may examine the activity closely (SSA publication).
