Section 823 of the Bipartisan Budget Act of 2015 (BBA) instructs Social Security to conduct a new five-year demonstration project, the POD, to test a benefit offset. In general, benefits are offset on a monthly basis $1 for every $2 earned above the greater of the Trial Work Period (TWP) amount or itemized impairment-related work expenses, and the TWP and Extended Period of Eligibility do not apply. The new rules apply to all volunteers that are randomly assigned to the two treatment groups, and these volunteers receive POD-specific benefits counseling. One treatment group has their benefits terminated if they are in full offset for 12 consecutive months, while the other only has benefits suspended. For participants whose benefits terminate, Medicare coverage will continue for 93 months. All volunteers provide written informed consent to participate and may withdraw from the project at any time. We are conducting the project in parts or all of the following states: Alabama, California, Connecticut, Maryland, Michigan, Nebraska, Texas, and Vermont. Recruitment began in January 2018 and ended in December 2018. Participation in the project, which is voluntary, will end June 2021.
