Court: IRS Sharing 1.28M Immigrant Tax Records With ICE Was Illegal

What the IRS Actually Did

Here's the sequence of events. ICE wanted the last known addresses of 1.28 million people it suspected of being undocumented immigrants. The IRS, which holds that information because people filed taxes, handed over roughly 47,289 taxpayer records in 2025 under a newly adopted data-sharing policy designed to support the administration's mass deportation agenda. Then a lower court blocked the policy. The IRS had already made the handoff.

The U.S. Court of Appeals for the District of Columbia Circuit upheld that injunction on Tuesday, finding the IRS violated a federal tax-confidentiality law that has been on the books since Watergate. Yes, Watergate. The law exists specifically because Congress decided, after watching Richard Nixon weaponize government agencies against his enemies, that tax records should not be a free buffet for federal law enforcement. The IRS apparently needed a reminder.

The Part That Should Make Everyone Uncomfortable

The court's ruling, written by U.S. Circuit Judge Cornelia Pillard, identified several ways the IRS procedure violated federal law. The most damning one is almost cartoonishly bad. According to Fox News, when ICE submitted requests for information on 1.28 million taxpayers, it listed the same single person as the point of contact for every single request. Every one. All 1.28 million.

Judge Pillard called the IRS's failure to catch this "most egregious." The law requires ICE to identify a federal employee "personally and directly engaged" in a qualifying investigation of a specific taxpayer. What ICE did instead was essentially clone-stamp one name across more than a million forms and hand it back. The IRS accepted it. This is the system that was processing your neighbors' private financial information.

Pillard wrote that the procedure "automates the review of millions of records without any individual review or any other means of ensuring compliance with the legal prerequisites to releasing each individual taxpayer's information." In plain English: nobody was actually checking anything. They just ran it through a machine and called it law enforcement.

The Administration's Argument, Such As It Was

The Trump administration appealed the lower court's injunction, arguing the ruling hindered federal law enforcement. That's the whole argument. It makes things harder, therefore it should not apply.

Judge Pillard had a tidy response to that. "But that's a gripe with Congress, not the court," she wrote. Which is a polite judicial way of saying: you don't get to ignore a law because following it is inconvenient. Congress wrote the tax-confidentiality statute. Congress can change it. Until then, it means what it says.

Who This Law Was Actually Protecting

The three-judge panel also ruled that the data-sharing procedure violated privacy rights, including those of noncitizens. The court found that by creating a separate automated pathway specifically for ICE to request noncitizens' tax information, the IRS stripped those taxpayers of protections the law guarantees to everyone who files a return, regardless of immigration status.

That matters because these 47,000-plus people filed taxes. They participated in the tax system, which the federal government has long encouraged undocumented immigrants to do, precisely because it generates revenue and, implicitly, promised a degree of confidentiality in return. The Trump administration's move turned that implicit arrangement into a trap. File your taxes, provide your address, receive a deportation officer. A Department of Homeland Security spokesperson told Reuters the agency disagrees with the ruling and will keep using "every lawful tool available" to locate people for removal. The court just ruled this particular tool was not lawful. So.

Where This Goes From Here

The injunction stands. The IRS cannot share taxpayer addresses with ICE under the current procedure. Whether the administration tries to redesign the data-exchange process to actually comply with the law, appeals to the Supreme Court, or simply waits for a friendlier political moment is an open question.

What is not an open question is that 47,289 records were already shared before any court could stop it. Those addresses are already sitting somewhere in ICE's systems. The court can block future disclosures. It cannot un-ring a bell.
