To encourage employment for individuals with disabilities, the Social Security Administration (SSA) offers special provisions that limit the impact of work on Social Security Disability Insurance (SSDI) or Supplemental Security Income (SSI) benefits. These provisions are called work incentives and include the Plan to Achieve Self-Support (PASS), Impairment-Related Work Expenses (IRWE), and Blind Work Expenses (BWE).
