Corporate transparency act: from 33 million companies to legal limbo

Corporate transparency act: from 33 million companies to legal limbo

Rule Changes

Courts, Congress, and two administrations battle over who must disclose business ownership

December 16th, 2025: Eleventh Circuit Unanimously Upholds CTA

Overview

Updated May 19

Congress passed the Corporate Transparency Act in 2021 to crack down on shell companies used for money laundering and terrorist financing, requiring 33 million U.S. businesses to report their true owners to FinCEN. Courts in Alabama and Texas declared it likely unconstitutional.

The Supreme Court stepped in. Within hours, a second Texas judge issued a nationwide injunction. Now the law exists in regulatory purgatory.

The Eleventh Circuit upheld it as constitutional in December 2025. In March, the Trump Treasury Department exempted all domestic companies—shrinking the pool from 33 million to roughly 12,000 foreign entities. What began as the biggest anti-money laundering reform in decades has become a case study in judicial ping-pong and administrative reversal.

  1. FinCEN Exempts All Domestic Companies

    Regulatory

    Interim final rule redefines "reporting company" to mean only foreign entities registered in U.S., exempting all 33 million domestic companies and shrinking scope to 12,000 businesses.

  2. Trump Treasury Announces Enforcement Suspension

    Policy

    Department of Treasury announces it will suspend CTA enforcement against U.S. citizens and domestic reporting companies, signaling major policy reversal.

  3. FinCEN Begins Accepting Reports

    Implementation

    Beneficial ownership information registry opens. Existing companies have until January 1, 2025 to file; new companies created in 2024 have 90 days from formation.

  4. FinCEN Publishes Reporting Rule

    Regulatory

    Treasury's Financial Crimes Enforcement Network issues regulations requiring 33 million reporting companies to disclose beneficial ownership information, with implementation beginning January 2024.

  5. Corporate Transparency Act Becomes Law

    Legislative

    Congress overrides Trump veto of National Defense Authorization Act, enacting the Anti-Money Laundering Act of 2020 containing the CTA. Law targets anonymous shell companies used for money laundering and terrorist financing.

Scenarios

1

Congress Repeals CTA Entirely, Shell Companies Return

Possible

Discussed by: Rep. Warren Davidson (R-OH) with 68 House co-sponsors; Senators Rand Paul and Tommy Tuberville introduced companion bill

The Repealing Big Brother Overreach Act gains momentum as Republicans control Congress and the White House. The law is repealed as government overreach, with supporters arguing state incorporation laws are sufficient. Anti-money laundering advocates warn the U.S. reopens the door to illicit finance, becoming the go-to jurisdiction for anonymous shell companies. Financial institutions absorb the full burden of beneficial ownership verification under Bank Secrecy Act requirements without the FinCEN database to cross-check claims.

2

Trump Exemption Becomes Permanent, Foreign-Only Regime Survives

Likely

Discussed by: Legal analysts at Simpson Thacher, Stinson, and other major law firms tracking the March 2025 interim rule

The March 2025 interim final rule exempting domestic companies becomes permanent after the public comment period. The CTA exists on paper as constitutional law following the Eleventh Circuit decision, but enforcement focuses exclusively on approximately 12,000 foreign entities registered in the U.S. This satisfies political opponents who see it as targeting foreigners rather than American small businesses, while gutting the law's original anti-money laundering purpose since most shell company abuse involves U.S.-formed entities. Appeals in Texas Top Cop Shop become moot as administrative action achieves what courts couldn't.

3

Future Administration Revives Full Enforcement Against 33 Million Companies

Possible

Discussed by: Transparency International, FACT Coalition, and anti-corruption advocates; implied risk in legal firm advisories

A future administration reverses the Trump Treasury's March 2025 exemption through new rulemaking, reinstating the original reporting requirements for all 33 million domestic companies. The Eleventh Circuit's constitutional blessing provides legal foundation. The Supreme Court's Texas Top Cop Shop stay signals the high court wouldn't block enforcement. Businesses face regulatory whiplash for a second time, with companies that never filed suddenly scrambling to meet new deadlines. This scenario creates the compliance chaos and uncertainty that defined the CTA's first four years.

4

Fifth Circuit or Supreme Court Declares CTA Unconstitutional

Unlikely

Discussed by: Constitutional scholars and defense lawyers in ongoing litigation; dissenting opinions in lower court rulings

The Fifth Circuit reverses course in Texas Top Cop Shop appeal or another challenge reaches the Supreme Court on different grounds than the procedural stay. A majority finds the CTA exceeds Congress's Commerce Clause authority or violates the Tenth Amendment by commandeering traditional state corporate registration functions. The nationwide injunction becomes permanent. FinCEN shuts down the beneficial ownership database. The law dies not through repeal but judicial nullification, with the Eleventh Circuit's contrary ruling creating a circuit split that the Supreme Court resolves against the government.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

1970-present

Bank Secrecy Act Creates Financial Institution Reporting Regime

Congress passed the Bank Secrecy Act in 1970, requiring financial institutions to report cash transactions over $10,000 and file suspicious activity reports to help detect money laundering. Banks became responsible for customer due diligence, including verifying beneficial ownership of business accounts. The law survived constitutional challenges and created FinCEN as the enforcement agency. Over five decades, reporting requirements expanded to cover more transaction types and lower thresholds.

Then

Banks absorbed significant compliance costs, passing customer information to law enforcement on a massive scale.

Now

The BSA became accepted infrastructure for anti-money laundering efforts, with financial institutions accepting their role as government reporting agents.

Why this matters now

The CTA attempted to shift beneficial ownership reporting from financial institutions to the companies themselves, but after Trump's exemption of domestic companies, banks remain the primary gatekeepers under BSA requirements—returning to the pre-CTA status quo.

2012-2021

Affordable Care Act Individual Mandate Litigation

The Supreme Court rejected constitutional challenges to the ACA three times over nine years. First, Chief Justice Roberts upheld the individual mandate as a tax in 2012. Then the Court preserved subsidies in King v. Burwell in 2015. Finally, in 2021, the Court dismissed a third challenge on standing grounds. Justice Alito called it the Court's "epic Affordable Care Act trilogy," each time pulling off an "improbable rescue" of the law when it faced serious threats.

Then

The ACA survived repeated attempts to dismantle it through litigation despite initial constitutional doubts.

Now

The law became entrenched despite ongoing political opposition, with courts increasingly reluctant to second-guess major legislation.

Why this matters now

Like the ACA, the CTA faces a pattern of repeated legal challenges and Supreme Court interventions, with the law surviving on narrow procedural or technical grounds even as its practical enforcement changes dramatically.

2017-2025

Trump-Biden Regulatory Whiplash

The Trump administration rolled back over 100 environmental rules, while Biden reversed 62 of Trump's 219 executive orders in his first 100 days. Federal courts upheld Trump-era environmental rules in only 20 percent of challenges, versus the historical 70 percent rate. The Biden administration used litigation abeyances, Congressional Review Act repeals, and delayed implementation to reverse Trump policies. The second Trump administration immediately began reversing Biden's late-term regulations on emissions, overtime pay, and healthcare.

Then

Businesses faced compliance uncertainty as rules changed with each administration, making long-term planning impossible.

Now

Regulatory stability eroded as partisan rule-making and swift reversals became normalized across administrations.

Why this matters now

The CTA's trajectory from Biden enforcement to Trump exemption mirrors the broader pattern of regulatory flip-flopping between administrations, leaving businesses in perpetual uncertainty about compliance obligations.
