How substantial gainful activity can trigger a rejection of your SSDI claim

After a lifetime of driving delivery trucks all day, the unthinkable happens. You injured yourself while on duty, causing you to develop a disabling condition. But even with the pain, you think of getting part-time work to provide food for your family.

Unfortunately, under federal Social Security rules, pushing through the pain to earn a little extra cash can accidentally destroy your chance at receiving Social Security Disability Insurance (SSDI) benefits.

The technical rule about securing part-time jobs

When applying for SSDI benefits, part of the assessment includes reviewing your substantial gainful activity (SGA). Under federal law, this refers to work that involves significant physical or mental duties you perform to receive payment. Earning more than the current SGA limits can make the government think that you are healthy enough to work a regular job.

In 2026, the non-blind SGA limit is $1,690 per month and $2,830 for statutory blind individuals. If your monthly gross earnings pass either of these by even a few dollars, the SSA will issue a technical denial. They will not evaluate how badly your back or neck hurts, or how hard it is to provide for your kids.

Seek legal feedback on your application before filing

The rules of the Social Security Administration (SSA) about SSDI eligibility can be overwhelming to navigate alone. While online guides exist to help you, you might miss technical errors that can derail your application.

You do not have to carry this heavy logistical burden all by yourself. Speaking with an experienced disability attorney can help you structure your path safely.
