What Is Beneficial Ownership? UBO Requirements for Crypto Compliance
Clear definition of beneficial ownership covering identification requirements, ownership thresholds, verification procedures, and regulatory frameworks for digital asset firms.
What Is Beneficial Ownership?
Beneficial ownership identifies the natural person(s) who ultimately own or control a legal entity, regardless of whether that ownership is held directly or through chains of intermediary entities.
Regulatory Foundation and FATF Standards
Beneficial ownership transparency is a cornerstone of the global AML/CFT framework. FATF Recommendations 24 and 25 require countries to ensure that adequate, accurate, and up-to-date information on the beneficial ownership of legal persons (Recommendation 24) and legal arrangements such as trusts (Recommendation 25) is available to competent authorities. FATF’s March 2022 revision of Recommendation 24 significantly strengthened requirements, mandating a multi-pronged approach to beneficial ownership transparency that includes beneficial ownership registries, obligations on financial institutions to identify beneficial owners during customer due diligence, and obligations on the legal entities themselves to obtain and maintain beneficial ownership information.
In the United States, FinCEN’s Customer Due Diligence (CDD) Rule (31 CFR 1010.230), effective May 2018, requires covered financial institutions to identify and verify the beneficial owners of legal entity customers at account opening. The rule defines beneficial owners using two prongs: the ownership prong (each individual who owns 25% or more of the equity interests of the entity) and the control prong (one individual with significant responsibility for managing the entity, such as the CEO, CFO, or managing partner). The Corporate Transparency Act (CTA), enacted in January 2021 with reporting requirements phased in from January 2024, created a separate obligation for companies themselves to report beneficial ownership information directly to FinCEN’s Beneficial Ownership Information (BOI) database. The CTA uses a lower threshold of 25% and captures a broader range of reporting companies, though it includes 23 exemptions for entities already subject to substantial regulatory oversight.
The EU’s Anti-Money Laundering Directives have progressively tightened beneficial ownership requirements. The 4th AML Directive (4AMLD) required member states to establish central beneficial ownership registries. The 5th AML Directive (5AMLD) mandated public access to those registries, though the Court of Justice of the EU (CJEU) struck down the public access provision in its November 2022 ruling in joined cases C-37/20 and C-601/20, finding it incompatible with the right to privacy under the EU Charter of Fundamental Rights. Access is now limited to competent authorities, FIUs, obliged entities conducting CDD, and persons with a legitimate interest. The EU’s forthcoming AML Regulation (AMLR), expected to apply from 2027, will set a harmonized 25% ownership threshold and require member states to maintain interconnected beneficial ownership registries accessible through the European Central Platform.
How Beneficial Ownership Verification Works in Practice
When a digital asset business onboards an entity customer, such as a corporate treasury seeking to hold crypto assets, a trading firm, or a DAO with a legal wrapper, the compliance team must conduct beneficial ownership identification as part of the KYC verification process. The process begins with collecting the entity’s formation documents (certificate of incorporation, articles of association, partnership agreement, or trust deed), shareholder register or equivalent ownership documentation, and organizational chart showing the complete ownership chain from the entity up to the ultimate natural person beneficial owners.
For a straightforward structure, a company with three individual shareholders holding 40%, 35%, and 25% respectively, all three individuals are beneficial owners under the 25% threshold and must be identified and verified. Verification typically requires government-issued photo identification, proof of address, and screening against sanctions lists and PEP databases for each beneficial owner. The complexity escalates rapidly with layered structures. Consider a company owned 60% by another company, which is in turn owned 50% by a trust, whose beneficiaries include a family office with four individual beneficiaries. The compliance team must trace through each layer, calculating effective ownership percentages at each level, until reaching the natural persons. If no natural person meets the 25% threshold after look-through, the senior managing official of the legal entity customer is identified as the beneficial owner under the control prong.
For crypto-native entities, additional challenges arise. DAOs structured through foundation entities in jurisdictions like the Cayman Islands or Switzerland may have diffuse governance token holders with no single individual meeting the ownership threshold. The compliance team must identify the individuals who exercise control over the DAO’s operations, treasury, or smart contract upgrade keys. Multi-signature wallet arrangements where key holders control entity funds may create beneficial ownership obligations for those key holders.
Jurisdiction Comparison
United States. FinCEN’s CDD Rule applies a 25% ownership threshold (ownership prong) plus a single control person (control prong). The Corporate Transparency Act requires reporting companies to file beneficial ownership reports with FinCEN, with updates required within 30 days of any change. Willful failure to report carries civil penalties of up to $500 per day and criminal penalties of up to $10,000 and/or two years’ imprisonment. As of early 2026, FinCEN has received over 9 million BOI reports.
European Union. The 4AMLD/5AMLD framework requires obliged entities (including CASPs under MiCA) to identify beneficial owners using a 25% ownership threshold. Member states maintain beneficial ownership registries, though access rules vary following the CJEU ruling. CASPs conducting CDD on entity customers must verify beneficial ownership information against the relevant member state registry and document any discrepancies. The upcoming AMLR will require CASPs to report discrepancies between their CDD findings and registry information to the relevant national authority. See our MiCA compliance guide for CASP-specific CDD obligations.
United Kingdom. Companies House maintains the Persons with Significant Control (PSC) register under the Small Business, Enterprise and Employment Act 2015. The PSC threshold is 25% of shares or voting rights, or the right to appoint or remove the majority of the board. The Economic Crime (Transparency and Enforcement) Act 2022 extended registration requirements to overseas entities owning UK real property and introduced an identity verification requirement for directors and PSCs, being implemented in phases through 2026. FCA-registered crypto firms must verify beneficial ownership as part of CDD under the MLRs 2017.
Singapore. The Companies Act requires Singapore-incorporated companies to maintain registers of registrable controllers (beneficial owners holding 25% or more of shares or voting power, or with the right to appoint or remove directors). Information is filed with the Accounting and Corporate Regulatory Authority (ACRA) and is not publicly accessible but is available to law enforcement and regulatory authorities. DPT service providers licensed by MAS must identify and verify beneficial owners under MAS Notice PSN02.
Common Compliance Challenges
The most persistent challenge is verifying beneficial ownership in complex, multi-layered structures, particularly those spanning multiple jurisdictions with different disclosure standards. Nominee arrangements, where a nominee shareholder holds shares on behalf of an undisclosed principal, are specifically designed to obscure beneficial ownership and require enhanced due diligence measures, including declarations from nominees identifying the persons on whose behalf they act. Bearer shares, though increasingly prohibited or immobilized (the EU, UK, and many other jurisdictions have effectively eliminated them), may still exist in structures established in certain offshore jurisdictions.
Maintaining accurate beneficial ownership information over time is a second major challenge. Ownership structures change through share transfers, capital raises, mergers, and reorganizations. FinCEN’s CDD Rule requires institutions to update beneficial ownership information when they become aware of changes, but does not prescribe a specific periodic refresh cycle. Best practice for digital asset businesses is to refresh beneficial ownership verification at least annually for all entity customers and upon any trigger event (significant change in transaction patterns, negative media, or change in the entity’s directors or officers). Integrating beneficial ownership verification with ongoing transaction monitoring and suspicious activity reporting processes ensures that changes in ownership that affect risk assessment are captured and acted upon.
