Social Security Disability Insurance can provide vital income for people who can no longer work because of a serious medical condition.
But qualifying for SSDI in 2026 is not automatic. The programme is designed for workers who paid into Social Security through payroll taxes and later developed a disability that meets the Social Security Administration’s strict rules.

According to CBS News, applicants generally must clear three major hurdles: they need a qualifying disability, enough work credits, and earnings low enough to show they cannot perform substantial gainful activity.
That makes SSDI different from Supplemental Security Income, which is based more heavily on financial need. SSDI is tied to a person’s work history.
Who qualifies for SSDI in 2026?
The first requirement is medical.
The SSA says a person must have a physical or mental condition that prevents them from doing substantial work. The condition must be expected to last at least 12 months or result in death.
Short-term injuries usually do not qualify. Partial disability also generally does not qualify under Social Security rules.
Applicants must also have enough work credits. In most cases, workers need a sufficient recent work history and a long enough overall record of paying Social Security taxes.
The exact number of credits depends on age. Younger workers may qualify with fewer credits, while older applicants generally need more.
Work and income limits matter
The third major test is whether the applicant can still perform substantial gainful activity.
In 2026, the SSA says earnings above $1,690 per month usually count as substantial gainful activity for non blind applicants. For blind applicants, the 2026 threshold is $2,830 per month.
If someone earns more than those limits through work, their claim may be denied even if they have a serious medical condition.
That does not mean every dollar of income counts the same way. The SSA has different rules for self-employment, work attempts, and certain support programmes.
People already receiving SSDI may also be able to test a return to work through a trial work period. In 2026, any month with earnings over $1,210 before taxes counts toward that trial period.
For new applicants, though, the core test is simple: the disability must be severe, long-lasting, and serious enough to prevent meaningful work.
