IRS-ICE Data Sharing Ruling: A federal appeals court in Washington allowed the Internal Revenue Service to keep sending taxpayer names and addresses to Immigration and Customs Enforcement, even as a separate court in Massachusetts is still blocking Homeland Security from acting on that same data. The result is a legal split that leaves millions of ITIN holders, visa workers, and green card holders unsure whether the tax return they file this year could end up in an enforcement file. For a policy built on the promise that tax records stay private, that uncertainty is the story.
The dispute traces back to an April 2025 memorandum of understanding between the Treasury Department and the Department of Homeland Security, signed by Treasury Secretary Scott Bessent and Homeland Security Secretary Kristi Noem. Under that agreement, ICE can ask the IRS to confirm the last known address of a person already facing a final removal order or a criminal investigation. Courts have since found parts of that process unlawful, ICE admitted it received addresses based on incomplete requests affecting roughly 1.28 million people, and the fight is now expected to move toward the Supreme Court. We will be updating this article monthly as new rulings come in, so bookmark this page if immigration status or tax filing affects you or your family.
What the IRS ICE Data Sharing Agreement Actually Says
The memorandum of understanding lets ICE submit a name, date of birth, and address to the IRS under Section 6103 of the tax code, which normally keeps tax records confidential except in narrow situations tied to criminal investigations. The government argues that requests limited to people with a final deportation order fall within that exception. Immigrant rights groups argue the real purpose is civil immigration enforcement, not criminal prosecution, and that handing over address data for immigration enforcement stretches the law far beyond what Congress intended when it wrote the taxpayer privacy statute decades ago.
Court filings show ICE originally sought data on close to seven million taxpayers, though the number actually processed through the agreement is far smaller. As of the most recent court filings, the IRS confirmed it disclosed information tied to about 47,000 individuals before a judge stepped in.

Why Green Card Holders Should Still Pay Attention
Lawful permanent residents are not the primary target of the memorandum, which is aimed at people with final removal orders or open criminal investigations. Still, immigration lawyers point to real reasons green card holders should not tune this story out.
Shared last names, shared addresses in multi-family housing, and outdated IRS records have already caused documented misidentification problems. Judge Talwani specifically flagged the risk that people living at the same address as someone under investigation could be swept up by mistake. A green card holder who has ever shared a household with a relative facing immigration proceedings is not automatically shielded from confusion in the data matching process.
There is also a naturalization angle. Immigration officers reviewing an application for citizenship or a green card renewal can request tax filing history, and any gap in filed returns or unresolved back taxes tends to draw scrutiny regardless of the ICE agreement. Filing accurately and on time remains the safest path for anyone with a pending immigration case.
Impact on ITIN Holders and Undocumented Taxpayers
Individual Taxpayer Identification Number holders, most of whom are immigrants without a Social Security number, are the group most directly affected by the IRS ICE data sharing agreement. The IRS created the ITIN program decades ago specifically so that people could pay taxes regardless of immigration status, and it built trust in that system by keeping the data confidential.
That trust has visibly cracked. Community tax preparers and legal aid groups report that filings among undocumented taxpayers dropped noticeably this filing season as fear spread that a tax return could become a roadmap for ICE. Research groups including the Yale Budget Lab estimate that reduced compliance tied to the agreement could cost the federal government tens of billions of dollars in lost revenue in a single fiscal year, since undocumented workers have historically paid tens of billions annually in federal taxes without being eligible for most of the benefits those taxes fund.
Tax attorneys generally still advise ITIN holders to file. Failing to file creates its own paper trail and can complicate a future adjustment of status case, while the current court injunctions mean ICE cannot lawfully act on data obtained through the agreement in the jurisdictions where those orders apply.

What Immigration Attorneys Are Telling Clients Right Now
Legal aid organizations are giving fairly consistent guidance while the litigation plays out.
File your taxes on time using either a Social Security number or an ITIN, since an incomplete filing history can create separate immigration complications later.
Keep your address on file with USCIS and the IRS accurate and consistent, since mismatched records are part of what has caused misidentification concerns in court filings.
Talk to an immigration attorney before making any change to how or whether you file, particularly if you have a pending case, a prior removal order, or a shared address with someone who does.
Save copies of tax filings, notices, and any correspondence, since attorneys expect further litigation and possible legislative responses to Section 6103 in the coming months.
The Path to the Supreme Court
With one federal appeals panel siding with the government and a district court in Massachusetts still blocking DHS from using the data, legal analysts widely expect the conflict to eventually reach the Supreme Court. Congress could also step in directly, since lawmakers have discussed amending Section 6103 to close or clarify the exact language the courts are currently fighting over. Until either happens, the practical result is a patchwork: the rules protecting your data may depend on which federal circuit you live in.

FAQs
Is the IRS currently sharing taxpayer data with ICE?
Yes, in the jurisdictions covered by the D.C. Circuit Court ruling, the IRS can currently share limited name and address information with ICE for people who already have a final removal order or an open criminal case. In Massachusetts and any area covered by that district court’s injunction, ICE and DHS remain blocked from using data obtained through the agreement.
Does this affect green card holders directly?
Not in most cases, since the agreement is aimed at people with final deportation orders or criminal investigations. However, shared addresses, common surnames, and IRS data errors have already caused documented misidentification concerns, so green card holders with a family member in removal proceedings should be cautious and speak with an attorney.
Should undocumented immigrants stop filing taxes because of this ruling?
Most immigration and tax attorneys still recommend filing. Unfiled returns can create separate problems for a future immigration case, and the injunctions currently in place limit what ICE can lawfully do with any data it receives.
What information can ICE actually request from the IRS?
Under the memorandum of understanding, ICE can request a taxpayer’s name, address, and date of birth tied to a specific enforcement case. It does not give ICE open access to full tax returns or income details.
Will this case go to the Supreme Court?
Legal experts widely expect it will, given the conflicting rulings from the D.C. Circuit and the Massachusetts district court. No date has been set, and the case could also be affected if Congress amends the underlying tax privacy law.
How can I find out if my own information was shared?
There is currently no public individual lookup tool. Immigration attorneys and organizations like the Center for Taxpayer Rights are tracking the litigation and can advise individuals who believe they may be affected.
Conclusion
The IRS ICE data sharing agreement remains one of the most closely watched immigration and tax policy disputes of 2026. With courts split on whether the arrangement is lawful, ITIN holders, green card holders, and anyone with a pending immigration matter are left navigating real uncertainty during an active tax season. The safest approach for most people is to keep filing accurately, keep address records consistent across agencies, and get individualized legal advice rather than relying on rumors.
