Federal appeals court greenlights IRS sharing taxpayer data with ICE for immigration enforcement

A three-judge panel on the U.S. Court of Appeals for the D.C. Circuit handed the Trump administration a significant legal win Tuesday, declining to block the IRS from sharing certain taxpayer data with Immigration and Customs Enforcement. The ruling rejected a preliminary injunction sought by Centro de Trabajadores Unidos and other nonprofit groups that had sued the federal government to shut down the data-sharing arrangement.

Judge Harry T. Edwards wrote that the plaintiffs "are unlikely to succeed on the merits of their claim," finding that the information being shared is not covered by the IRS privacy statute the groups invoked. In short: the legal challenge didn't have the goods, as ABC News reports.

Attorney General Pam Bondi called the decision a "crucial victory" for the administration.

"Deporting illegal aliens makes the American people safer."

She's right. And the ruling clears a path for one of the more creative tools in the administration's immigration enforcement arsenal to keep operating.

How the agreement works

The data-sharing agreement was signed last April by Treasury Secretary Scott Bessent and Homeland Security Secretary Kristi Noem. Under its terms, ICE can submit names and addresses of illegal immigrants inside the United States to the IRS for cross-verification against tax records. The goal is straightforward: use existing federal data to locate people who are in the country illegally.

The numbers tell an interesting story about the program's scope and its limits. Of the 1.28 million names ICE submitted to the IRS, the agency was only able to verify roughly 47,000. For less than 5% of those verified individuals, the IRS provided ICE with additional address information.

That's a narrow funnel, not a dragnet. The program cross-references existing records. It doesn't create new surveillance. It doesn't target legal residents or citizens. It identifies people who are already known to be in the country illegally and checks whether the IRS has useful location data on them.

The left's real objection

The nonprofit plaintiffs framed this as a privacy issue. But the court found the shared information isn't even covered by the relevant IRS privacy statute. That's a fatal flaw in the legal argument, and the judges saw through it.

The deeper objection from the left isn't really about privacy. It's about enforcement itself. For years, a quiet consensus existed in Washington that certain federal databases would remain siloed, that the IRS would never talk to ICE, that illegal immigrants could file taxes using Individual Taxpayer Identification Numbers and remain invisible to immigration authorities. The implicit promise was: give us your tax revenue, and we won't ask questions.

That arrangement served a particular political purpose. It allowed politicians to collect tax revenue from illegal immigrants while simultaneously claiming the immigration system was too broken to enforce. Revenue without accountability. The data-sharing agreement breaks that unspoken deal, and that's what really animates the opposition.

The erroneous sharing problem

Earlier this month, court filings revealed the IRS had erroneously shared the taxpayer information of thousands of people with the Department of Homeland Security as part of the agreement. This is a legitimate concern worth taking seriously. Government agencies handling sensitive data need to get it right, and errors affecting thousands of records demand correction.

But the existence of implementation errors is not an argument for scrapping the program. It's an argument for fixing the errors. Every large-scale federal data operation produces mistakes. The question is whether the underlying authority is lawful and the purpose is legitimate. The court answered both questions in the administration's favor.

It's also worth noting that the acting IRS commissioner resigned last year over the deal. That tells you something about the institutional resistance this administration faces even within its own agencies. Career officials who spent years maintaining the firewall between tax data and immigration enforcement weren't going to surrender that territory quietly.

Enforcement as policy, not cruelty

The left treats every new enforcement mechanism as inherently suspect. Each tool is framed as an escalation, a threat, an assault on vulnerable communities. What this framing conveniently ignores is that enforcement is what makes law meaningful. A statute without enforcement is a suggestion.

The administration has argued that the data-sharing agreement helps carry out the president's agenda to secure U.S. borders. It fits within a larger nationwide immigration crackdown that has included deportations and workplace raids. Each of these measures reinforces the same principle: immigration law exists, and the federal government intends to apply it.

Consider the alternative the plaintiffs were asking for. They wanted a federal court to order the IRS to refuse cooperation with a sister federal agency engaged in lawful enforcement activity. They wanted one arm of the government to actively obstruct another. The court declined to impose that kind of institutional sabotage.

What comes next

The ruling doesn't end the litigation. It denies a preliminary injunction, which means the program continues while the case proceeds. But the court's finding that plaintiffs are unlikely to succeed on the merits is a strong signal. It suggests the legal foundation beneath this challenge is weak and getting weaker.

For the administration, the decision validates a model that could extend beyond immigration. The principle that federal agencies can share data to support lawful enforcement objectives is a powerful one. If the IRS can cross-reference records with ICE, similar cooperation between other agencies becomes harder to challenge.

For the open-borders coalition, this is a problem that won't be solved in court. The legal arguments failed because the law doesn't say what they wish it said. The privacy statute doesn't cover what they claimed it covered. The judges read the text and ruled accordingly.

The federal government has 1.28 million names on a list. It now has the legal green light to keep checking them against tax records. The era of the firewall is over.
