Corporate Transparency Act (CTA): What Compliance Teams Need to Know
A complete guide to the Corporate Transparency Act (CTA) — who must file, what's disclosed, FinCEN BOI access, exemptions, and what it means for KYB and AML compliance professionals.
What is the Corporate Transparency Act?
The Corporate Transparency Act (CTA) was enacted as part of the Anti-Money Laundering Act of 2020 (AMLA 2020) and became effective January 1, 2024. It represents the most significant expansion of US AML/KYB requirements in decades.
The CTA requires most US legal entities — corporations, LLCs, limited partnerships, and similar entities — to file Beneficial Ownership Information (BOI) reports with the Financial Crimes Enforcement Network (FinCEN), a bureau of the US Treasury. The goal is to eliminate anonymous shell company ownership in the US and bring US corporate transparency standards in line with FATF recommendations and European UBO register requirements.
Who Must File Under the CTA?
Reporting companies are US domestic entities (corporations, LLCs, limited partnerships) formed by filing a document with a secretary of state, AND foreign entities registered to do business in the US.
Deadlines:
- Entities formed before January 1, 2024: Had until January 1, 2025 to file initial BOI report
- Entities formed in 2024: Had 90 days from formation to file
- Entities formed after January 1, 2025: Must file within 30 days of formation
- Updates: Any change in beneficial ownership must be reported within 30 days
Note on legal uncertainty: The CTA faced constitutional challenges in 2024, with some federal courts issuing injunctions. Compliance teams should monitor FinCEN guidance for the current status of enforcement.
Who is a Beneficial Owner Under the CTA?
A beneficial owner is any individual who, directly or indirectly:
1. Owns or controls 25% or more of the ownership interests of the reporting company, OR
2. Exercises substantial control over the reporting company
Substantial control includes: serving as a senior officer (president, CEO, COO, CFO, general counsel, or any officer with similar authority); having authority to appoint or remove senior officers or a majority of the board; directing, determining, or having substantial influence over important decisions.
What must be reported: Full legal name, date of birth, current residential address, and a unique identifying number (driver's license, passport, or FinCEN identifier).
Company applicants: For entities formed after January 1, 2024, the individual(s) who directly filed the formation document must also be reported as "company applicants."
Who is Exempt from the CTA?
The CTA contains 23 categories of exempt entities — most are already subject to substantial federal or state regulatory oversight. Key exemptions:
- Large operating companies: 20+ full-time US employees, US physical office, $5M+ in gross receipts/sales from US-source income
- SEC-reporting companies: Registered with the SEC and required to file 10-K/10-Q (most public companies)
- Banks and credit unions regulated by federal banking agencies
- Investment companies registered under the Investment Company Act
- Insurance companies regulated by state insurance commissioners
- Accounting firms licensed by a state board of accountancy
- Tax-exempt entities registered as 501(c) organizations
- Inactive companies: Formed before January 1, 2020, not engaged in business, no foreign owners, no assets, no change in ownership in past 12 months
Most Fortune 500 companies are exempt as SEC-reporting companies or large operating companies. The CTA primarily targets smaller private entities, LLCs, and shell companies.
How Can Compliance Teams Access BOI Data?
The FinCEN BOI database is not publicly accessible. Access is limited to:
- Federal, state, local, and tribal law enforcement with a court order or similar process
- US financial institutions for KYB/CDD purposes — under the Bank Secrecy Act, financial institutions can request BOI to comply with CDD requirements with customer consent
- Federal functional regulators supervising financial institutions
- Foreign law enforcement through a US agency intermediary
- Treasury Department personnel for tax administration and national security
For KYB practitioners: You cannot directly query the FinCEN BOI database. Instead:
1. Request a self-certified UBO declaration from the counterparty
2. Ask them to share their FinCEN BOI filing number as proof of filing
3. Cross-reference against publicly available data — SEC ownership tables, 13D/13G filings, proxy statements
4. Use commercial databases (Dun & Bradstreet, Bureau van Dijk/Orbis, etc.) for enhanced due diligence
CTA vs European UBO Registers: Key Differences
The CTA is often compared to the EU's AML Directive (AMLD) beneficial ownership register requirements, but there are key differences:
| Feature | CTA (USA) | EU AMLD UBO Registers |
|---|---|---|
| Public access | No — law enforcement + FIs only | Yes — publicly accessible (most EU states) |
| Threshold | 25% equity or substantial control | 25% equity (default) |
| Exemptions | 23 categories (large companies exempt) | Fewer exemptions in most EU states |
| Penalties | Up to $500/day civil; criminal | Varies by member state |
| Regulator | FinCEN (Treasury) | National company registries |
The CTA is less transparent than European UBO registers but represents a major step forward from the pre-2024 situation where the US had no federal beneficial ownership disclosure requirement.
