This is one of the most financially stressful questions in the entire process, because the waiting is long and bills don’t pause. The short answer: limited work is possible, but the rules are strict, the limits are hard lines rather than guidelines, and working near the line is one of the most common ways otherwise strong claims get sunk.
The substantial gainful activity (SGA) limit
SSDI’s core test is whether you can engage in substantial gainful activity. Social Security defines this primarily through a monthly earnings threshold that adjusts annually (with a higher threshold for blind applicants). Earn above the SGA level in a month, and Social Security will generally find you not disabled for that period regardless of your diagnosis, that’s how central this number is.
Because the threshold changes yearly, check the current figure on ssa.gov or ask us directly rather than relying on any fixed number you find in an article.
Why working below the limit still carries risk
Staying under the dollar limit keeps you technically eligible, but the work itself becomes evidence. An examiner or judge looks at what you’re doing, not just what you’re paid: if you’re working 20 hours a week doing tasks similar to your old job, the natural question becomes whether you could do more. Part-time work that involves the same abilities your claim says you’ve lost is the specific pattern that damages cases.
Work that fits poorly-paid, heavily accommodated, or sporadic patterns, a few hours here and there, special employer accommodations, frequent absences due to your condition, reads very differently than steady part-time work, and documenting those accommodations and limitations matters if you do work at all.
Unsuccessful work attempts
Social Security recognizes that people try to work and fail because of their conditions. A short-lived work attempt that ended due to your disability can be classified as an unsuccessful work attempt rather than evidence against you, but the documentation of why it ended matters enormously. If you tried to go back and couldn’t, get that reason in writing wherever possible, doctor’s notes, employer records, anything contemporaneous.
The mistakes that actually sink claims
Earning over SGA “just for one month” to cover an emergency. Working under the table, which creates both a benefits problem and a much bigger legal one. Social media showing activity inconsistent with claimed limitations. And not reporting work activity at all, which reads as concealment even when the work itself would have been permissible.
After approval: different rules
Once approved, SSDI has separate work-incentive programs, including a trial work period allowing you to test working without immediately losing benefits. Those post-approval rules are more forgiving than the application-stage rules, which is worth knowing so you don’t assume the strictness is permanent.
How this interacts with the rest of your claim
Work history and earnings records feed directly into the evaluation covered in our guide on what conditions qualify for SSDI, and if a denial happens, work activity is one of the first things addressed on appeal, covered in our denial and appeals guide. If the financial pressure driving the work question is severe, our guide on SSDI vs. SSI covers whether needs-based SSI may be available in the meantime, and our timeline guide helps you plan for how long the road realistically is.

Frequently Asked Questions
Can I work part time while applying for SSDI? Limited work under the substantial gainful activity threshold is technically permitted, but work resembling your previous job or suggesting greater capacity than claimed can damage the case even under the limit.
What is substantial gainful activity? The earnings level Social Security uses to define disqualifying work, set as a monthly dollar threshold that adjusts each year.
What if I tried to work and my condition forced me to stop? That can be treated as an unsuccessful work attempt rather than evidence against you, especially with documentation showing the condition caused the stop.
Do I have to report small amounts of work? Yes. Unreported work reads as concealment and creates worse problems than the work itself would have.
