Federal Judge Blocks IRS from Sharing Taxpayer Data with ICE

United States District Court District of Columbia

A federal judge has issued a preliminary injunction, temporarily blocking a controversial agreement that would have allowed the U.S. Internal Revenue Service (IRS) to share sensitive taxpayer information with Immigration and Customs Enforcement (ICE). The ruling, delivered by Judge Paul L. Friedman of the U.S. District Court for the District of Columbia, puts a halt to a plan that critics argued would undermine the integrity of the tax system and target immigrant communities.

The case centers on a Memorandum of Understanding (MOU) established in April 2025, which outlined a process for the IRS to provide ICE with data, including names and addresses, of individuals with final orders of removal. The government contended that this data sharing was permissible under a specific exception to federal tax privacy laws, intended to aid in the enforcement of federal criminal statutes. However, advocacy groups filed a lawsuit, arguing the agreement was an unlawful overreach.

In his decision, Judge Friedman stated that the plaintiffs were likely to succeed on their claim that the MOU violates federal law protecting the confidentiality of tax returns. He wrote that the government's interpretation of the legal exception was "unpersuasive," finding that the risk of irreparable harm to the plaintiffs and the public’s trust in the tax system outweighed the government's stated interests. Immigrant advocates had warned that such a policy would create a chilling effect, discouraging millions of immigrants, regardless of their status, from filing taxes for fear their information could be used for deportation.

The preliminary injunction stops the data-sharing agreement from being implemented while the case proceeds. Proponents of the injunction argued that the long-standing separation between tax administration and civil immigration enforcement is crucial for the U.S. tax system. This legal battle highlights the ongoing tensions surrounding immigration policy and the use of federal agency data for enforcement purposes. The decision is seen as a significant, albeit temporary, victory for immigrant rights organizations that challenged the policy.
