Ultimate Beneficial Owner (UBO)

Identifying the Ultimate Beneficial Owner is a core requirement of any Know Your Business (KYB) and Anti-Money Laundering programme. Criminals frequently hide behind layered corporate structures — holding companies, trusts, nominee shareholders, and offshore entities — to obscure who really benefits from an account or transaction. UBO identification cuts through those layers to reach the human being at the end of the ownership chain.

Most regulatory frameworks, including the EU Anti-Money Laundering Directives and FATF Recommendation 24, set a beneficial ownership threshold of 25%, though firms applying a risk-based approach may set lower thresholds for higher-risk customers. Where no individual meets the ownership test, the senior managing official is typically recorded as the beneficial owner.

What does UBO mean?

A UBO is the real person behind a company. The legal owner is whoever appears on the share register — often another company, a trust or a nominee. The beneficial owner is the individual who ultimately benefits from, owns or controls that company, however many layers sit in between. A UBO is always a natural person, never a company.

A company can have several UBOs, or none who meet the ownership threshold — in which case the person who exercises control by other means, or failing that the senior managing official, is recorded instead.

How to identify a UBO: a worked example

The structure. PQR Corporation is wholly owned by LMN Corporation. LMN Corporation is owned 50% by Mr Santos and 50% by Ms Garcia.

The calculation. Indirect ownership is found by multiplying the percentages down the chain. Mr Santos owns 50% of LMN, which owns 100% of PQR, so he indirectly owns 50% × 100% = 50% of PQR. The same applies to Ms Garcia.

The answer. Both Mr Santos and Ms Garcia are UBOs of PQR Corporation — each holds 50%, well above the common 25% threshold. LMN Corporation is not a UBO because a UBO must be a natural person.

A second example. If Ms Tan owns 60% of HoldCo, and HoldCo owns 40% of TargetCo, Ms Tan's indirect stake in TargetCo is 60% × 40% = 24% — just under a 25% threshold. She may still be a UBO if she controls TargetCo by other means, and a firm applying a lower threshold for a higher-risk customer would record her regardless. Because she controls HoldCo, rules that attribute a controlled company’s whole stake, such as the UK PSC regime and the EU AML Regulation’s rule for mixed chains, would treat her as a beneficial owner of TargetCo.

Which document shows the UBO?

The key document is an ownership structure chart (organisational chart): a diagram showing every legal entity and natural person in the ownership chain and their percentage holdings. It is what lets you trace ownership through intermediate companies to the people at the end. The chart should be supported by registry extracts or share registers for each entity, and by identity documents for each UBO — collecting the chart is not the same as verifying it.
