Appeals Court Upholds Block on IRS-ICE Data Sharing

A federal appeals court on Tuesday reaffirmed a lower court’s decision to block the Internal Revenue Service from providing Immigration and Customs Enforcement (ICE) with the last known addresses of millions of taxpayers. The U.S. Court of Appeals for the D.C. Circuit, in a unanimous opinion from a three‑judge panel, held that ICE’s broad request for personal data exceeded the authority granted to the agency and violated privacy protections. The ruling follows a 2023 district court judgment that deemed the request “unreasonable and overly broad,” and the appeals court agreed that the data sharing would have an undue chilling effect on taxpayers’ willingness to comply with tax filings.

The panel emphasized that the IRS is bound by strict confidentiality rules and that the requested information would be used for enforcement purposes that are not directly tied to tax compliance. The court noted that the request covered “millions of addresses,” many of which belonged to individuals with no known tax‑related connection to ICE’s investigations. In its analysis, the court cited statutory limits on the IRS’s data‑sharing authority and the lack of a clear statutory or regulatory basis for ICE to obtain such personal information. The decision underscores the judiciary’s willingness to scrutinize interagency data requests that raise significant privacy concerns.

The ruling is expected to limit future attempts by ICE to obtain taxpayer data through the IRS, although the agency may seek alternative legal avenues or narrower requests. The case highlights the ongoing tension between immigration enforcement objectives and taxpayer privacy rights, and it may prompt a reassessment of data‑sharing protocols between federal agencies. The decision remains in effect pending any further appeals, and it signals a judicial preference for protecting individual privacy in the face of expansive enforcement requests.
