National Treasury Employees Union Sues IRS to Protect Workers and Tax System

The National Treasury Employees Union joined a federal lawsuit against the IRS between August 6 and 9, challenging an Immunity Order that shields President Donald Trump and his family from federal tax audits. The union says the arrangement puts career employees in conflict with their duty to apply tax laws evenly.

The filing adds the union as a plaintiff in Floyd v. Department of Justice. It challenges an agreement included in the settlement of a $10 billion lawsuit Trump filed against the IRS.

NTEU National President Doreen Greenwald described the dispute as a test of equal treatment under the tax system.

"The integrity of our tax system depends on one fundamental principle: every taxpayer is subject to the same laws and the same standards. When political actors direct employees to treat certain taxpayers differently, it undermines public confidence in our tax system and places dedicated civil servants in an impossible position."

Greenwald made the statement August 6. The union argues that the order conflicts with the Internal Revenue Code’s prohibition on presidential interference in audits and violates the U.S. Constitution’s Emoluments Clause.

The case reaches the courts as IRS employees face separate disputes with the agency over their workplace rights. The workers are litigating the February 27 termination of their collective bargaining agreement and the removal of union materials from IRS workplaces.

The lawsuit follows a year of conflict over taxpayer data

A federal judge found in February 2026 that the IRS violated federal law approximately 42,695 times by sharing confidential taxpayer addresses with Department of Homeland Security and Immigration and Customs Enforcement officials. The disclosures occurred under a data-sharing agreement involving Treasury Secretary Scott Bessent and former DHS Secretary Kristi Noem.

The finding intensified concerns about whether tax information could be used for purposes beyond tax administration. The union’s new challenge focuses on a different question: whether political officials can direct IRS employees to treat selected taxpayers differently.

The case also unfolds alongside more forceful immigration-enforcement directives. DHS Secretary Markwayne Mullin issued a warning July 15.

"Illegal aliens will be arrested and deported wherever they are. If you are here illegally, LEAVE NOW."

The statement added pressure to an already tense environment for federal employees whose work connects tax administration, immigration enforcement and government data systems.

IRS employees say the order creates a legal conflict

The union’s position centers on the work performed by career IRS employees. Advocacy groups argue that immunity for the president’s family undermines equal treatment and could encourage taxpayers to disregard their obligations.

Employees, meanwhile, face what the union characterizes as an impossible choice. They could follow political instructions to ignore particular tax filings, or follow their legal oath to administer tax laws impartially.

The challenge therefore seeks to protect both workers and the administration of the tax code. Its constitutional claim invokes the Emoluments Clause, while its statutory claim relies on restrictions in the Internal Revenue Code.

The agreement’s connection to Trump’s lawsuit gives the dispute a financial dimension as well. The tax-audit protection formed part of a settlement connected to his $10 billion claim against the agency.

DOJ rescinded a proposed $1.8 billion fund

The litigation follows another administration decision involving claims of political targeting. Acting Attorney General Todd Blanche rescinded a proposed $1.8 billion Anti-Weaponization Fund August 2.

The fund had been intended to compensate people who alleged that the government targeted them for political reasons. Blanche’s formal rescission order said the program never began distributing money.

"This Order establishes, beyond any doubt, that there is no Fund. no funds were transferred; no process for receiving claims was established; no claims were paid."

The rescission removes one avenue for compensation claims while the union pursues its challenge to the tax-audit agreement in federal court. Together, the disputes place questions about political retaliation, agency independence and employee obligations before the administration and the courts.

NTEU’s case also gives IRS employees a direct role in the challenge. Rather than leaving the dispute solely to taxpayers or advocacy groups, the union argues that the order changes the conditions under which its members must perform their jobs.

The February collective-bargaining dispute remains separate from the audit case. It still shapes the union’s broader conflict with the agency, including the removal of union materials from workplaces.

The government’s approach to agency oversight has shifted across departments during the same period. On August 5, U.S. Citizenship and Immigration Services issued a policy update that tightened evidence standards for immigration benefit requests and said it was aimed at restoring integrity to the immigration system. That policy is outside the tax lawsuit, but it reflects the administration’s wider emphasis on agency enforcement and system integrity.

The lawsuit’s immediate claims remain tied to IRS audits, federal tax law and the settlement agreement. The court will have to consider the union’s challenge to the order and its claims under the Internal Revenue Code and the Constitution.

The union joined the case during the August 6–9 window. Its legal challenge now places the treatment of the president and his family, the duties of IRS employees and the reach of presidential authority in the same proceeding.
