Ultimate Beneficial Owners
Ultimate beneficial owners are the natural persons who ultimately own or control a company or other legal entity, directly or through a chain of companies, trusts or nominees. Anti-money-laundering rules require banks, payment firms and other regulated businesses to identify and verify them, usually starting from a 25% ownership or voting test, before serving the entity.
- Also known as
- UBO, Ultimate beneficial owner, Beneficial owner, Person with significant control, PSC
- Used at
- onboarding and periodic review of business customers by regulated firms; counterparty checks in lending, investment and M&A; filings with national company registers
- Binding
- yes — the UK's Money Laundering Regulations 2017 (more than 25% of shares or votes, or control) and the Companies House register of people with significant control, in place since 6 April 2016; the EU anti-money-laundering directives (25% plus one share as an indication of ownership), succeeded by the EU AML Regulation from 2027; in the US, FinCEN's customer due diligence rule (anyone with 25% or more of the equity, plus one individual with significant responsibility to control or manage the company)
- Fallback
- in the UK, where every possible means has been exhausted and no owner found, a firm may treat the senior person managing the company as its beneficial owner, and must record what it tried
- Registers are a start, not proof
- UK firms may not rely solely on register data, and since March 2025 FinCEN no longer requires US companies to report their beneficial owners at all
- Trusts
- the beneficial owners include the settlor, the trustees, the beneficiaries (or the class of them) and anyone else who controls the trust
- Sanctions link
- under UK sanctions an entity owned more than 50% or controlled by a designated person is caught by the freeze even if it is not itself listed
How ultimate beneficial owners work in practice
Finding the UBO means climbing the ownership chain until only people are left. A UK company applying for a business account is 70% owned by a Luxembourg holding company and 30% by its founder, who is a UBO. The holding company is owned by two funds and a family trust; the firm must look through each layer to see whether anyone reaches the threshold indirectly or controls the company through board appointment rights or a veto, and for the trust it must identify the settlor, trustees and beneficiaries. Indirect stakes can be counted by multiplying holdings down the chain or by following majority control at each level, the method the UK's PSC rules use; careful firms run both. If nobody qualifies, the senior managing official is recorded, with the steps taken.
Thresholds are floors, not safe harbours. Four relatives with 24% each who act together, a nominee holding shares for someone else, or a shareholder agreement giving one investor control of the board can each amount to ownership or control. Complex cross-border structures and politically exposed owners call for enhanced due diligence; every UBO is screened against sanctions and PEP lists.
In a transaction the question runs both ways. A buyer of a regulated fintech tests the UBO work in its customer files, and the target's own ownership changes at completion: new register filings, refreshed KYC with its banks and partners and, for an FCA-authorised firm, payment and e-money institutions included, the regulator's prior approval of the new controller.
Example
A payment institution onboards a UK online marketplace. The registry shows two shareholders: a Cyprus holding company with 60% and a Delaware LLC with 40%. The Cyprus company is owned 50/50 by two individuals, so on a look-through basis each holds 30% of the marketplace — both UBOs. The LLC's members hold 40%, 35% and 25% of it, indirect stakes of 16%, 14% and 10%, all below the threshold. But the shareholder agreement lets the LLC appoint two of the marketplace's three directors, and the LLC's managing member decides who: control, so a third UBO. All three are verified and screened; one is the brother of a serving minister, the file moves to enhanced due diligence, and onboarding takes nine days instead of one.
Common mistakes
- Stopping at the first corporate shareholder instead of tracing ownership to people. - Reading 25% as the only test and missing control through board rights, vetoes or agreements. - Accepting a register extract as verification. - Naming the senior manager as UBO without recording why no owner could be found. - Screening the company but not its owners, although a sanctioned owner with more than 50% freezes the company too. - Letting the file go stale after a funding round, a secondary sale or an acquisition changes who owns the customer.
