What are Significant Beneficial Ownerships, and How to Identify Them

“In 2012, HSBC paid a $1.92 billion settlement to US authorities after prosecutors found that shell companies, none of whose actual controllers had ever been properly verified, were used to move hundreds of millions of dollars for drug cartels and sanctioned states.” 

The compliance failure was not a data error. It was a structural one: the bank could detect the entities it was doing business with, but not the natural persons who actually controlled them.

That gap between a registered entity and its real-world owner is exactly what significant beneficial ownership (SBO) structures exist to close.

What Significant Beneficial Ownership Actually Means?

An SBO is a person who directly or indirectly holds a meaningful stake in or controls a legal entity. The term “significant” is important because it sets a regulatory standard, rather than simply explaining something.

The requirement to report information comes up when someone exceeds the established limit. The majority of jurisdictions do not require reporting when someone remains below the established limit.

Ownership and control are two different things. On one hand, ownership is measured in terms of percentage of shares, voting rights, or economic interest.

On the other hand, regulators examine the question of control with regard to day-to-day management, appointment/removal of directors, and entitlement to profits. 

An individual can be a significant beneficial owner without owning even one share of stock if they have effective control through a seat on the board, a contract, or a trust arrangement where they are the ultimate beneficiary.

The difference between ownership and control arises from the fact that most corporate fraud and financial crimes occur in the control dimension.

The Wirecard collapse illustrated this clearly: the structures that concealed the flow of €1.9 billion relied not on outright fake ownership but on a network of affiliated entities, nominee arrangements, and service agreements that kept the actual decision-makers one layer removed from any registry record.

Jurisdictional Divergence in SBO Thresholds

There isn’t one universal definitional threshold for “significant ownership” on a global scale to date. Therefore, compliance officers conducting cross-jurisdictional business must understand where the lines have been drawn in each jurisdiction.

• United States

“The FinCEN Customer Due Diligence Rule (31 CFR 1010.230) sets the threshold at 25% ownership for covered financial institutions verifying legal entity customers. In March 2025, FinCEN issued an interim final rule that revised the scope of the Corporate Transparency Act.” 

The domestic US entities are now exempt from beneficial ownership information reporting under the revised rule, while foreign entities registered to do business in the US must report non-US beneficial owners.

• European Union

“Under the Fifth Anti-Money Laundering Directive (5AMLD), Article 30, member states must maintain central registers of beneficial ownership. The threshold is generally 25% plus one share or 25% of voting rights, though member states can lower this for higher-risk sectors.” 

The EU’s forthcoming Anti-Money Laundering Regulation (AMLR), set for phased application from 2027, will replace the current patchwork of national implementations with a directly applicable harmonized standard.

• Singapore

Singapore has strengthened its register of controllers requirements under the Companies Act following the Monetary Authority’s July 2025 fine of S$27.45 million against nine financial institutions for failing to comply with beneficial ownership regulations.

In practice, when a company’s compliance team is onboarding a client across three jurisdictions, they’re likely facing three distinct compliance thresholds as the client onboards in each jurisdiction, differing disclosure timelines, and differing registries in each jurisdiction.

If there isn’t an automated jurisdictional mapping system, then the team’s workload will become unmanageable.

Now, the following section addresses the key challenges in identifying SBOs

Comprehensive Breakdown of Challenges of SBO Identification in KYB

The regulatory framework is clear enough. The operational challenge is where it fails.

Layered Corporate Structures

The UK regulations classify a natural person who owns 30 percent of a UK operating company that has three intermediate holding companies located in different countries as a major beneficial owner of the company. 

There is a way to identify them based on going through all the layers of how they operate. All the different layers operate under their own jurisdictions and apply their own regulations on record access, language requirements, and data standards.

Nominee Arrangements

Nominee arrangements are frequently used to separate the registered owner from the beneficial owner. A nominee director appears in the registry; the actual controller operates through a side agreement that never surfaces in any public filing. 

Thus, determining these needs goes beyond the registry record to documentation that nominees themselves are often unwilling to disclose.

Inconsistent Registry Standards

Even where beneficial ownership data is publicly available, the quality of data varies alot. For instance, registries in the MENA region have historically provided limited UBO data. 

While registries in the CIS countries often reflect formal ownership structures that do not correspond to effective control. 

Self-Declaration Reliance

Many SBO regimes, including India’s BEN-1 framework, rely on individuals declaring their own significant ownership. 

Where an individual has an interest in concealing ownership, sanctions exposure, PEP status, or involvement in adverse media, the self-declaration mechanism is where the disclosure gap arises.

Static Data

A beneficial ownership register entry from two years ago may be accurate as filed, but completely wrong today. Corporate restructuring, share transfers, trust updates, and trust deed updates do not necessarily require a re-filing.

Thus, all these challenges may create disruption in the verification process. However, strong platforms like The KYB can cater to it well.

How The KYB Traces Significant Beneficial Ownership

The KYB’s UBO Identification capability is designed to cater to the specific critical failures of technology. It pulls data directly from official government registries and corporate records, and not from aggregated or re-licensed databases in more than 250 countries and states. 

This matters for one practical reason: the data is legally authoritative. 

When a regulator or auditor asks how a beneficial owner was detected, the response “sourced from the official registry” carries a different weight than “sourced from a third-party data aggregator.”

The platform automatically traverses multi-layer ownership structures. Where a company’s registered shareholder is itself a legal entity, The KYB maps the next layer, and the layer after that, until it reaches the natural persons who meet the applicable beneficial ownership threshold. 

Moreover, corporate structure mapping is returned visually, giving compliance officers a clear view of the complete ownership graph rather than a flat list of registered shareholders.

For ongoing SBO monitoring, The KYB’s Perpetual KYB solution tracks verified business entities continuously. Changes in directors, ownership structure, and legal status trigger alerts, meaning a beneficial ownership profile that was accurate at onboarding remains legitimate throughout the relationship. 

For ongoing SBO monitoring, The KYB offers a Perpetual KYB solution, which tracks verified entities. Any changes to directors, structure, and status will raise an alert, ensuring that a beneficial ownership profile, which was correct at the time of onboarding, remains correct over time.

This closes the static data gap that periodic manual reviews cannot address.

The KYB’s business due diligence module facilitates a more thorough inquiry for high-risk counterparties, those with complicated offshore structures, high-risk jurisdictions, or PEP-linked ownership. It also involves affiliated-entity networks, source-of-funds indicators, and ownership evidence. 

This is especially important in multinational collaborations, high-value business transactions, and correspondent banking arrangements. It is because there is a lengthy chain of beneficial ownership and a significant degree of opaqueness in the relevant jurisdictions.

Frequently Asked Questions

• What is a Significant Beneficial Owner (SBO)?

A significant beneficial owner is a natural person who, directly or indirectly, holds a meaningful percentage of ownership or control in a legal entity, above the applicable regulatory threshold in the relevant jurisdiction.

• How Does SBO Differ from UBO?

The terms are often used interchangeably, but “significant beneficial owner” typically refers to ownership exceeding a defined threshold, while “ultimate beneficial owner” refers to the natural person at the top of any ownership chain, regardless of percentage held. In practice, SBO compliance frameworks focus on both.
