What concerns have been raised about Elon Musk's DOGE Service seeking access to the IRS's Integrated Data Retrieval System?

Elon Musk's DOGE Service is seeking access to the IRS's Integrated Data Retrieval System, which contains detailed financial information about every taxpayer, business, and nonprofit in the country. This system allows users to access sensitive data including personal identification numbers and bank information, and even permits entering and adjusting transaction data and generating notices. The request has sparked alarm within the tax agency because access to this system is extremely limited due to security concerns. The Washington Post reports that taxpayers whose information is wrongfully disclosed are entitled by law to monetary damages, indicating the serious nature of potential privacy breaches. IRS employees are deeply concerned about the security implications of granting such access to an external entity.
