Updates on Litigation over the IRS-ICE

Information-Sharing Agreement



March 26, 2026

On February 24, 2026, the U.S. Court ofAppeals for the D.C. Circuit (D.C. Circuit) affirmed the denial of
a preliminary injunction that would have placed restrictions on information sharing pursuant to an
agreement between the Internal Revenue Service (IRS) and Immigration and Customs Enforcement
(ICE). The agreement at issue establishes procedures between the two agencies to share information for
the enforcement of criminal immigration laws. A previous Legal Sidebar discussed the background of the
information-sharing agreement, the legal questions at issue in the case (Centro de Trabajadores Unidos v.
Bessent), and the parties' arguments before the appeals court. While the decision from the D.C. Circuit
was pending in Centro, the U.S. District Courts for the District of Columbia and the District of
Massachusetts each granted injunctions against information sharing pursuant to the agreement.
This Legal Sidebar discusses the reasoning of the D.C. Circuit's decision in Centro and legal questions
that remain. It discusses the two separate cases in the U.S. District Courts and the injunctions granted in
them. It focuses on the D.C. Circuit's and the district courts' decisions about the permissibility of the
disclosures under the Internal Revenue Code (I.R.C.). Finally, it discusses congressional reactions to the
court cases and subsequent developments related to the information-sharing agreement, including the
IRS's admission that it had disclosed information based on incomplete and insufficient address
information.


D.C. Circuit's Decision in Centro

The D.C. Circuit affirmed the district court's denial of a preliminary injunction to restrain IRS
information sharing. As a threshold matter, the court found sufficient associational standing by at least
one of the organizational plaintiffs to allow the case to proceed. Turning to the preliminary injunction
factors, the court held that the plaintiff organizations are unlikely to succeed on the merits. The court
found that the information-sharing agreement is not a reviewable final agency action under the
Administrative Procedure Act (APA) because it merely clarifies existing statutory duties and does not
create binding legal duties. On the substantive arguments regarding whether disclosures contemplated by
the agreement violated the law, the court held that the I.R.C. likely permits the disclosure of tax return
information as contemplated by the information-sharing agreement between IRS and ICE.
