What are the main privacy concerns regarding Elon Musk's DOGE group accessing IRS records?

The primary concern is that this non-governmental entity would have access to highly sensitive personal data, including Social Security numbers and banking information that Americans provide when filing taxes. Privacy advocates worry about what DOGE might do with this information or the potential security risks if the entity were hacked. While third-party auditing of government systems is standard practice, the unprecedented nature of someone like Elon Musk accessing these records has raised significant alarm. Several groups are now suing to block DOGE from accessing these private IRS records due to data security implications.
