Part-time work does not automatically terminate SSDI or SSI, but “part time” is not the legal test. Earnings, work activity, applicable work incentives, and the benefit program determine the result. Report work even when you expect to remain below a threshold. [1]
Rules that determine the answer
SSDI can involve a trial work period, an extended period of eligibility, and substantial-gainful-activity rules. SSI generally adjusts payments using countable earned income and exclusions; section 1619 can preserve Medicaid under specified conditions. Self-employment has additional evaluation rules beyond the amount withdrawn from a business account. [1] [2]
Medical improvement reviews and earnings reviews are related but distinct. Free benefits counseling can help model the actual effect on cash payments and health coverage before the first paycheck, without assuming a permanent loss of every benefit.
What to check before taking the next step
- Before starting, ask which work-incentive stage applies and obtain the current year’s relevant earnings amounts.
- Check the award or decision letter to confirm whether the payment is retirement, SSDI, a dependent benefit, SSI, or a combination. These programs can apply different income and reporting rules.
- Keep pay stubs, hours, subsidies, impairment-related work expenses, and employer accommodations, and give SSA the relevant dates and amounts rather than only an estimate.
- Ask for a written explanation of any change. If you disagree, use the review procedure and deadline on the notice, and retain proof that SSA received your request.
Practical example
A person works ten hours weekly but earns a high hourly wage. Limited hours alone do not establish that the work falls below SSA’s applicable earnings test.
