D.C. District Court Sides With CHC Legal Arguments in Restricting IRS-ICE Data Sharing Over Privacy Concerns

CHC Leadership’s Amicus Brief Assisted D.C. District Court in Blocking IRS Disclosure of Taxpayer Information to ICE

This week, the U.S. District Court for the District of Columbia sided with concerns raised by Congressional Hispanic Caucus (CHC) and advocates, moving to restrict the unprecedented data sharing and temporarily blocking the IRS from disclosing taxpayer information to Immigration and Customs Enforcement (ICE) without providing the court and plaintiffs with 24-hour notice.

The CHC leadership filed an amicus brief last week in Center for Taxpayer Rights v. Internal Revenue Service, opposing a new Memorandum of Understanding (MOU) that allows the IRS to share sensitive taxpayer information, including home addresses, with ICE.

CHC leadership stressed that Congress has been clear: taxpayer confidentiality is the law. The IRS-ICE MOU abandons decades of precedent, undermines trust in the tax system, and risks chilling voluntary compliance. Such fear-driven deterrence could ultimately weaken federal revenue by discouraging immigrant families from filing taxes with Social Security Numbers (SSNs) or Individual Taxpayer Identification Numbers (ITINs).
