Key Takeaways
• Judge Dabney Friedrich ruled IRS can share tax data with DHS for criminal immigration cases, not civil enforcement.
• IRS may only provide information to Homeland Security when tied to active criminal investigations, not for mass deportations.
• Advocacy groups worry limited data-sharing could broaden in future, increasing risks for undocumented immigrants filing taxes.
A recent court decision has sparked strong reactions across the immigration field, marking a key development for both government enforcement strategies and the millions of people living in the United States 🇺🇸 without legal immigration status. Judge Dabney Friedrich decided that the Internal Revenue Service (IRS) is allowed to share certain tax data with the Department of Homeland Security (DHS) if it’s related to criminal investigations. While the Trump administration views this as an important win in its push for tougher immigration action, advocates and legal experts say the ruling leaves important questions about privacy and enforcement.
Let’s unpack exactly what happened, why it matters, and how it could affect people in the country, employers, and the broader immigration discussion.
The Court’s Decision: What Did Judge Dabney Friedrich Rule?
On May 12, 2025, Judge Dabney Friedrich delivered a clear and careful decision in a case brought by immigrant rights organizations. The groups wanted to stop the IRS from giving taxpayer information to the Department of Homeland Security. Their main argument was that such sharing broke privacy protections created by Section 6103 of the Internal Revenue Code. This section is meant to make sure that taxpayer information stays private and can’t be used for just any government purpose.
However, Judge Dabney Friedrich ruled in favor of the government, writing:
“At its core, this case presents a narrow legal issue: Does the Memorandum of Understanding between the IRS and DHS violate the Internal Revenue Code? It does not.”
She explained that the agreement doesn’t break the law because it only allows the IRS to provide information if there’s a linked criminal investigation—not simply for broad or civil immigration cases. This means the IRS cannot just hand over tax data for mass deportations or wide sweeps, but only in cases attached to possible crimes.
The decision is seen as a legal win for the Trump administration, which has pushed to increase immigration enforcement, including using new tools and information-sharing.
How the Data-Sharing Agreement Works
The core of the debate is a Memorandum of Understanding (MOU) between the IRS and the Department of Homeland Security. Here’s how the process actually unfolds:
- Immigration and Customs Enforcement (ICE), which is part of the DHS, submits names and addresses of people it suspects are breaking immigration laws.
- The IRS checks its records. Most undocumented immigrants pay taxes using an Individual Taxpayer Identification Number, or ITIN. When someone applies for an ITIN, they provide their name and address—details that can help match IRS records to ICE requests.
- If there is an ongoing criminal investigation related to that person, the IRS may give updated address information to the DHS.
It’s important to note that IRS records are usually very well protected by law. The rules only allow the IRS to share this information if it’s linked directly to a criminal probe, not for general immigration enforcement or simply because someone is in the country without status.
What Protects Taxpayer Data? Understanding IRS Privacy Rules
Tax data privacy is a core principle for the IRS. The relevant law, Section 6103, makes it clear that taxpayer information is considered confidential and cannot be freely shared with other agencies or departments. Even within the IRS, most employees can’t access this information unless they need it for their work.
Under the current arrangement:
- Only information requests tied to specific criminal investigations are allowed.
- Mass data requests or broad searches are not approved.
- The purpose cannot simply be “to find undocumented immigrants”; it must relate directly to a suspected crime.
This balance tries to protect the privacy of anyone who files taxes, whether they’re a citizen, a legal immigrant, or someone living in the country without documents.
Why Are Tax Records Key for Immigration Enforcement?
Millions of people in the United States 🇺🇸 without lawful status still pay taxes every year, often to show good faith or simply because employers require it. They use the IRS’s Individual Taxpayer Identification Number since they usually don’t have a Social Security Number. When they apply for an ITIN, they report their current name and address to the IRS.
That makes IRS records a useful tool for law enforcement, since those details are hard to find elsewhere. By using updated address information, ICE can more easily locate someone for a criminal investigation.
But the threat to privacy is also clear: if the rules changed and broader sharing was allowed, millions of people who tried to follow tax laws could suddenly face new risks of enforcement.
Limits on How Data Can Be Used
Judge Dabney Friedrich’s decision relies on the fact that serious limits exist on how data can be shared. The IRS can only respond to requests that tie a taxpayer to a criminal case. For example:
- If the DHS is investigating someone for drug trafficking or fraud, and that person is suspected of also breaking immigration laws, ICE can ask the IRS for any recent address connected to the case.
- The IRS can only send details about that person—not about their family members, neighbors, or others who filed taxes nearby.
- The information cannot be used for wide searches or to power general deportation drives.
This framework is meant to stop what some advocates fear: the use of IRS data for sweeping action against whole groups of people, rather than for case-by-case enforcement tied to criminal activity.
Concerns Raised by Advocacy Groups
Immigrant rights groups filed the lawsuit because they fear the government will not limit itself to criminal cases alone. They argue:
- Even limited sharing creates a chilling effect, making people afraid to file taxes.
- The definitions of “criminal investigation” may broaden over time, leading to more requests.
- There is little transparency about how often the IRS grants such requests or how the DHS uses information afterward.
While Judge Dabney Friedrich found that the current arrangements do not harm plaintiffs because only criminally linked data is shared, advocacy groups say that could change. If new agreements or interpretations expand sharing to civil enforcement cases, many more people might be affected. They want more clear protection and independent monitoring.
Political and Legislative Response
The court’s decision has divided political leaders. According to reports, Democrats in Congress have expressed deep concerns that even limited data-sharing opens the door to larger enforcement actions in the future. They have called for more rules and oversight, asking for greater transparency about:
- When and how often tax data is shared with immigration agencies,
- What steps are taken to prevent mistakes, and
- Whether the IRS informs taxpayers when their information is released.
Republican leaders, on the other hand, consider the judge’s decision a step forward in using all available government resources to support immigration laws and public safety.
The issue has also been picked up by the media, which has highlighted both the practical challenges for government agencies and the personal fears for people living in the country without legal status.
Historical Context: Tax Privacy and Immigration Enforcement
Historically, the rules around IRS data have been exceptionally strict to build trust in the tax system. People are more likely to file and pay taxes if they know their data won’t be used against them for non-tax matters. This broad trust is key to how the U.S. tax system works.
There have been rare but important exceptions for law enforcement. The Internal Revenue Code allows the IRS to disclose information if it helps criminal investigations—such as in cases of money laundering or fraud.
The new MOU between the IRS and the Department of Homeland Security fits into these older traditions, but it’s different because immigration law intersects with tax filing in unique ways. Many experts, both for and against the policy, agree that changing how private tax details are handled could have big ripple effects.
How the Ruling Affects Immigrants, Employers, and Agencies
For undocumented immigrants, the ruling may create new fears, even though the current agreement is supposed to be narrow. Some may worry that filing taxes could expose them or their families to investigation, even if they are not under criminal suspicion. As federal agencies grow more capable of using digital records, concerns about privacy can become stronger.
Employers may wonder how this decision will affect hiring and verification processes. Many businesses rely on tax procedures to document payments without directly violating immigration rules. Yet, the fear of future enforcement may change how some businesses hire or report employment taxes.
For the IRS and the Department of Homeland Security, the challenge is to balance privacy with law enforcement needs. They must apply clear rules so that only proper, specific requests are followed, and avoid extending these protocols in ways the law does not permit.
Judge Dabney Friedrich’s Reasoning: The Legal Details
The lawsuit against the IRS and the Department of Homeland Security centered on a narrow legal question: does giving tax data for criminal investigations break privacy laws? Judge Dabney Friedrich found that it does not, as long as the information is only shared for active criminal investigations, as outlined in the agreement between the IRS and DHS.
She made it clear that:
- The Memorandum of Understanding follows the letter of the Internal Revenue Code, specifically Section 6103.
- The agreement does not allow for the release of tax data for civil deportation cases or general enforcement sweeps.
By focusing on these two points, Judge Dabney Friedrich reassured that protections for taxpayer privacy—considered a cornerstone of the U.S. system—are still strong.
The Role of Congress and What Might Change Next
While the judge’s decision answers the question for now, Congress has the power to make further changes. Lawmakers could:
- Set clearer limits or rules on when IRS data can be shared with other agencies,
- Increase public reporting on how often these requests are made, or
- Even ban the sharing of IRS data for immigration investigations completely.
Such steps could ease the worries of those filing taxes with an ITIN while making enforcement priorities clearer and more consistent.

Looking Ahead: Impacts and Open Questions
As reported by VisaVerge.com, the broader impact of this ruling will depend on how policies evolve and whether new laws emerge. Trust between immigrant communities and the IRS may face pressure if people are not sure their tax details will stay private. If more information sharing is approved in the future, it could trigger a drop in tax filings and make it harder for authorities to collect needed revenue.
Yet, supporters of the agreement say that without some cooperation between the IRS and the Department of Homeland Security, authorities may be unable to track criminal suspects who are also violating immigration laws. The key will be continued oversight—making sure data is shared only when truly needed and with strong privacy safeguards in place.
For now, Judge Dabney Friedrich’s decision means the IRS can share data with the Department of Homeland Security, but only under strict, clearly defined circumstances. This ongoing debate will likely shape U.S. immigration and tax law for years to come, affecting millions of people and setting a powerful example for how to balance privacy and enforcement in a complex, changing world.
