State Attorneys General Sue to Challenge FinCEN’s Beneficial Ownership Reporting Rule
On October 27, 2026, the attorneys general of 20 states and the District of Columbia (the States) filed a lawsuit in the U.S. District Court for the District of Oregon challenging the U.S. Department of the Treasury Financial Crimes Enforcement Network’s (FinCEN) final rule eliminating beneficial ownership information (BOI) reporting requirements for U.S. companies and U.S. persons under the Corporate Transparency Act (CTA). The complaint asks the court to vacate FinCEN’s August 2026 final rule (the Final Rule) and the March 2025 interim final rule that preceded it (the IFR), and to halt FinCEN’s planned deletion of BOI previously reported by U.S. companies. The States argue that FinCEN effectively rewrote the CTA through rulemaking.
The lawsuit does not change existing reporting obligations. Unless a court orders otherwise, U.S. companies and their beneficial owners are not required to file BOI reports, while foreign reporting companies remain subject to the narrower requirements of the Final Rule. It is unclear whether FinCEN has already begun deleting previously reported BOI or whether the court will intervene to prevent its deletion. If the States prevail, BOI reporting requirements for domestic companies could potentially be reinstated.
Background: The CTA, the Reporting Rule, and the Final Rule
Congress enacted the CTA in 2021 to combat the misuse of anonymous shell companies by requiring entities to disclose their beneficial owners to a nonpublic FinCEN database. The statute defines “reporting company” to include two categories: domestic entities created by a filing with a secretary of state or similar office, and foreign entities registered to do business in the United States. It provides for 23 exemptions and permits the Secretary of the Treasury to add others only if reporting neither serve the public interest nor would be useful to law enforcement. FinCEN’s 2022 implementing rule (the Reporting Rule) took effect on January 1, 2024, and estimated that approximately 32.6 million entities would be required to report.
As discussed in our prior Updates, small businesses challenged the CTA on constitutional grounds, and in late 2024 and early 2025, federal courts alternately halted and reinstated enforcement, prompting FinCEN to suspend and then extend reporting deadlines. FinCEN then reversed course after the change in administrations. The IFR, published on March 26, 2025, exempted domestic reporting companies and U.S. person beneficial owners, and the Final Rule, issued on August 11, 2026, extended those exemptions and made them permanent. Under the Final Rule, only foreign entities registered to do business in the United States must report, and only for their non-U.S. person beneficial owners. FinCEN also announced that it would delete previously reported information about U.S. persons from its database.
The States’ Challenge
The complaint argues that the Final Rule and the IFR impermissibly rewrite the CTA by exempting nearly every entity Congress required to report. The Final Rule estimates that only 28,000 existing foreign reporting companies and 1,800 new ones will report in future years. The Reporting Rule, by contrast, estimated 32.6 million existing entities plus about 5 million new entities each year. The States argue that the CTA’s residual exemption authority allows the Secretary to exempt additional classes of entities, not to remove one of the two categories Congress expressly required to report. The States raise a similar objection to the exemption for U.S. persons, which FinCEN based on the Bank Secrecy Act’s general exemption authority rather than the CTA. They also allege that both rules are arbitrary and capricious, in part because FinCEN relied on burdens to small businesses that Congress had already weighed.
If the court vacates both the Final Rule and the IFR, the Reporting Rule’s domestic reporting obligations could return. The complaint does not address when those obligations would apply. As in 2024 and 2025, FinCEN would likely need to announce new filing deadlines. Until a court rules otherwise, however, the Final Rule remains in effect.
FinCEN’s BOI “Data Purge”
The complaint also asks the court to stay FinCEN’s plan to delete previously reported BOI, which the States characterize as the “Data Purge.” The Final Rule states that FinCEN intends to delete the reported information of newly exempt companies, and that FinCEN does not anticipate deleting information reported after February 10, 2027, which the States read to mean that the deletion will occur by that date. The States argue that the CTA requires FinCEN to retain reported information for at least five (5) years after a reporting company ceases to exist, and that a company does not cease to exist simply because FinCEN has exempted it. They also argue that BOI reports are federal records that may be destroyed only under schedules approved by the Archivist of the United States, and that no such approval exists. Finally, because the deletion plan first appeared in the Final Rule, the States contend that it was adopted without the required opportunity for public comment.
It is unclear whether FinCEN has begun deleting data or when the court will act on the stay request. The outcome will determine whether information that millions of companies have already submitted remains available to authorized agencies, and the States say they intend to use that information in fraud investigations, consumer protection matters, and tax enforcement.
Key Takeaways
- BOI obligations are unchanged pending a court order. The Final Rule remains in effect. U.S. companies and their beneficial owners do not need to file, update, or correct BOI reports, and foreign reporting companies should continue to comply with the Final Rule’s requirements for their non-U.S. person beneficial owners.
- The status of previously reported data is uncertain. Companies that filed BOI reports in 2024 or early 2025 should not assume that their information has been or will be removed from FinCEN’s database, particularly if the court stays the deletion.
- CTA reporting requirements could potentially return. Vacatur of the Final Rule and IFR could again subject U.S. companies to BOI reporting. Companies should be aware of the litigation and any resulting FinCEN guidance.
