IRS Discloses Confidential Immigrant Taxpayer Data to DHS in Error, Court Filing Reveals
WASHINGTON, D.C. — The Internal Revenue Service improperly disclosed confidential taxpayer information of thousands of individuals to the Department of Homeland Security, according to a recent court filing that has reignited concerns over privacy and immigration enforcement. The revelation stems from an agreement finalized last spring between the Treasury Department, the IRS, and DHS to share taxpayer data to assist immigration authorities in identifying individuals living in the country illegally.
The agreement authorized Immigration and Customs Enforcement (ICE) to submit names and addresses of suspected illegal immigrants to the IRS for cross-verification against tax records. IRS Chief Risk and Control Officer Dottie Romo disclosed in a declaration filed Wednesday that the IRS verified approximately 47,000 of the 1.28 million names ICE requested and subsequently shared this sensitive information with immigration officials.
This improper disclosure has led to significant fallout, including the resignation of top IRS officials involved in the arrangement. The data-sharing initiative, intended to bolster immigration enforcement efforts, has faced intense scrutiny from privacy advocates and lawmakers alike. Critics argue that the transfer of confidential tax information to immigration authorities undermines taxpayer trust and raises legal and ethical questions.
The IRS acknowledged the mistake and stated it is collaborating with federal agencies to address the issue and prevent further unauthorized disclosures. This development comes amid ongoing debates over immigration policy and the extent to which government agencies should share personal data.
The Department of Homeland Security, which oversees ICE, has defended the partnership as a tool to enforce immigration laws, but the incident has intensified calls for greater oversight and transparency. The controversy also follows a recent federal judge’s decision to block the IRS from sharing addresses with ICE, highlighting judicial concerns about privacy protections.

The IRS’s data practices are governed by strict confidentiality rules outlined on the IRS Privacy and Disclosure site. Additionally, the American Civil Liberties Union has been vocal in its criticism of such data-sharing agreements, emphasizing the potential for abuse and erosion of civil liberties.
As the government works to resolve the issue, thousands of taxpayers remain unaware that their private information was shared without proper authorization, raising concerns about the future handling of sensitive data in immigration enforcement efforts.
