Our objective was to determine whether the Social Security Administration (SSA) had adequate controls to ensure Old-Age, Survivors and Disability Insurance (OASDI) benefits that had been withheld pending a Supplemental Security Income (SSI) windfall offset determination were paid accurately and timely. ...
Based on our random sample, we estimate that:
35,398 beneficiaries had SSI windfall offset actions that were not processed. As a result, SSA withheld about $306 million in OASDI benefits, of which we estimate approximately $232 million is payable to these beneficiaries.
17,067 beneficiaries had SSI windfall offset actions that were incorrectly processed. As a result, SSA improperly withheld or overpaid about $51.5 million in OASDI benefits for these beneficiaries.
60,051 beneficiaries had SSI windfall offset actions that were correctly processed but not in a timely manner. As a result, these beneficiaries did not promptly receive about $725.9 million in OASDI benefits
