(Reuters) - The U.S. Internal Revenue Service has blocked a key aide to tech billionaire Elon Musk from accessing individual taxpayer returns or other personal information as part of a deal signed between the tax-collecting agency and the Trump administration.

The U.S. IRS has reached a contractual understanding with Gavin Kliger, an aide to Elon Musk, which restricts his access to sensitive taxpayer data. Signed by Treasury and OPM officials, this agreement aims to streamline IRS operations while safeguarding individual taxpayer privacy.

The Trump White House and Treasury Department officials have reached an agreement to limit DOGE's access to IRS data, citing privacy concerns.

Elon Musk’s Department of Government Efficiency is seeking access to the Internal Revenue Service’s highly sensitive taxpayer data system, a source familiar with the move tells CNN.

An IRS draft memo may grant a DOGE adviser broad access to taxpayer data, raising privacy concerns and sparking legal challenges.

The unusual request could put sensitive data about millions of American taxpayers in the hands of Trump political appointees.

The DOGE efforts at the IRS come as the Trump administration is moving to drastically reduce the size of the tax collection agency.
