Twenty-One States Sue Treasury Over Rule Exempting Most Businesses From Ownership Reporting

A coalition of 21 state attorneys general has filed a federal lawsuit to block a U.S. Department of the Treasury rule that excuses almost all companies from reporting who owns and controls them. The legal action, titled State of Oregon v. Bessent, was submitted on October 27, 2026, in the U.S. District Court in Eugene, Oregon.

The lawsuit challenges an August 2026 regulation issued by the Treasury Department’s Financial Crimes Enforcement Network (FinCEN). According to state officials, the federal rule exempts 99.9% of businesses from federal ownership disclosure requirements and includes plans to delete existing ownership records that could contain evidence of open criminal investigations.

The Corporate Transparency Act and FinCEN’s Exemption

Congress enacted the Corporate Transparency Act with bipartisan support in 2021 to prevent bad actors from using anonymous shell companies to hide illegal activities. The law mandated the creation of a Treasury database containing detailed information on business ownership and control. Law enforcement agencies rely on this database to follow financial tracks, trace stolen assets, and investigate illegal conduct such as money laundering, tax evasion, fraud, and political corruption.

The August 2026 FinCEN rule effectively halted those requirements by carving out exemptions for nearly all commercial entities. FinCEN further indicated that it intended to erase ownership records already stored in the system, which state attorneys general warn could undermine ongoing criminal inquiries across the country.

Legal Claims Raised by State Attorneys General

Led by Oregon Attorney General Dan Rayfield and Illinois Attorney General Kwame Raoul, the 21-state coalition argues that FinCEN and the federal government violated multiple federal laws, including the Corporate Transparency Act and the Administrative Procedure Act. The lawsuit asserts that federal regulators acted arbitrarily, lacked a reasonable justification, and failed to complete mandatory legal procedural steps prior to changing the rule.

In addition, the complaint states that federal officials failed to consult with the Secretary of Homeland Security and the U.S. Attorney General before granting the widespread exemptions, as required by law. Joining Colorado Attorney General Phil Weiser and the coalition leads are attorneys general from Arizona, California, Delaware, the District of Columbia, Maine, Maryland, Massachusetts, Michigan, Minnesota, Nevada, New Jersey, New Mexico, New York, North Carolina, Rhode Island, Virginia, Washington, and Wisconsin.

What the Challenge Means for Businesses and the Public

For ordinary citizens and business owners, the outcome of this lawsuit determines whether company ownership details must be reported to federal authorities. The state attorneys general are asking the federal district court to throw out the August 2026 rule and direct FinCEN to continue gathering and maintaining corporate ownership records for law enforcement use.

Because the litigation is currently pending, business owners should keep track of federal reporting requirements and court rulings. Companies that were previously subject to the Corporate Transparency Act do not need to take immediate new steps, but they should monitor regulatory announcements as the court considers whether to reinstate full reporting obligations.

Navigating federal business disclosure requirements and administrative regulations can be complex. Small-business owners and corporate leaders facing uncertainty about reporting obligations may benefit from consulting a business attorney.
