A holding company, a parent company and a subsidiary are three names for one relationship: a company that controls another.
Company law defines only two of them, and none of the three hides the founder at the top of the chain.
The short answer
| Term | What it means | Where it comes from |
|---|---|---|
| Holding company | The company that controls another | Company law in the UK, Hong Kong and Singapore |
| Subsidiary | The company that is controlled | The same sections |
| Parent company | The same controlling company | Accounting rules and everyday use |
| Wholly owned subsidiary | A subsidiary with no outside member | UK Companies Act 2006, section 1159(2) |
Hold on to three things:
- The legal test is control. "More than 50% of the shares" is only one way to meet it.
- "Holding" versus "parent" is a business habit, not two legal categories.
- A company placed between you and your subsidiary does not remove you from the registers.
What the law defines: holding company and subsidiary
In the United Kingdom, section 1159 of the Companies Act 2006 says a company is a "subsidiary" of another, its "holding company", if that other company:
- "holds a majority of the voting rights in it"
- "is a member of it and has the right to appoint or remove a majority of its board of directors"
- "is a member of it and controls alone, pursuant to an agreement with other members, a majority of the voting rights in it"
Hong Kong's Companies Ordinance sets its own three tests in section 13. Section 15 defines the subsidiary as the mirror image.
Singapore's Companies Act 1967 sets two tests in section 5(1). Sections 5A and 5B cover the "ultimate holding company" and the "wholly owned subsidiary"; we read their headings only.
| Test | United Kingdom, s. 1159 | Hong Kong, s. 13 | Singapore, s. 5 |
|---|---|---|---|
| Voting rights | Holds a majority | Controls more than half | Controls more than half of the voting power |
| Board | Is a member and can appoint or remove a majority | Controls the composition of the board | Controls the composition of the board |
| Agreement with other members | Is a member and controls a majority of the votes | Not a separate test | Not a separate test |
| Issued share capital | Not a separate test | Holds more than half | Not a separate test |
Two details matter to a founder:
- Votes, not shares. The UK test counts voting rights. Hong Kong adds issued share capital as a route of its own. On our reading of the two texts, Singapore does not.
- Board control is defined. In Hong Kong and Singapore it means the power to appoint or remove all the directors, or a majority, without anyone else's consent.
All three laws follow the chain down.
- Company A is the holding company of B.
- B is the holding company of C.
- C is therefore a subsidiary of A as well.
Where "parent company" comes from
"Parent" appears in none of these tests. It lives in the accounting rules.
Section 1162 of the UK Act uses a second pair for accounts: "parent undertaking" and "subsidiary undertaking". The Hong Kong ordinance refers to the same two notions and defines them in its Schedule 1.
The UK accounting test is wider than section 1159. An undertaking is a parent if it:
- holds a majority of the voting rights
- is a member and can appoint or remove a majority of the board
- has the right to exercise a dominant influence under the articles or a control contract
- is a member and controls a majority of the voting rights by agreement
- has the power to exercise, or actually exercises, dominant influence or control
- is managed on a unified basis with the other undertaking
Three tests.
- Majority of the voting rights
- Member, with the right to appoint or remove a majority of the board
- Member, controlling a majority of the votes by agreement
Six tests: the same three, plus:
- Dominant influence under the articles or a control contract
- Dominant influence or control, held or actually exercised
- Management on a unified basis
So one company can be a holding company under one section and a parent undertaking under another. "Parent company", the everyday form, has no definition in the sections we read.
3 questions
Which jurisdiction fits you?Answer three questions and get the three jurisdictions that match your situation.
Holding company vs parent company: a habit, not a category
Provider guides such as UpCounsel and SmartAsset draw this line:
- a holding company owns shares and does not trade
- a parent company owns shares and runs a business of its own
None of the statutes above draws it. In UK and Hong Kong company law, "holding company" is simply the legal name of the controlling company, whether it trades or not.
Two consequences:
- A trading company with one subsidiary is a holding company in law.
- A form asking for your "parent company" and one asking for your "holding company" ask the same question: who controls this entity?
Wholly owned subsidiary: more than "100%"
Guides say "100%". UK law puts it differently.
"A company is a 'wholly-owned subsidiary' of another company if it has no members except that other and that other's wholly-owned subsidiaries or persons acting on behalf of that other or its wholly-owned subsidiaries."
Read it in three steps:
- The test looks at who the members are, not at a percentage.
- Shares held by another wholly owned subsidiary of the same holding company do not break it.
- Shares held by a person acting on behalf of the holding company do not break it either.
In section 1159, "company" includes any body corporate, so the holding company of a UK company can be a foreign one.
These definitions speak of companies and bodies corporate, so a founder who owns the shares personally is a shareholder, not a holding company.
Subsidiary vs branch: two different questions
A branch is not a company, so it is neither a subsidiary nor a holding company.
Our Singapore guide sets the two side by side:
| Feature | Subsidiary | Branch |
|---|---|---|
| Legal status | Separate Singapore company | Extension of the foreign parent |
| Parent's liability | Ring-fenced | Parent fully liable |
| Tax treatment | Singapore resident | Taxed as a non-resident |
The full comparison is in subsidiary, branch or representative office in Singapore.
For other countries, keep the one principle our guides state: a branch is not a separate legal person.
A foreign company owns 100% of yours: four cases
You own a company abroad, and that company owns all the shares of a new one.
- 1You, the founderAn individual: a shareholder, never a holding company under the definitions read. Controller registers look for you above 25%, in Hong Kong directly or indirectly.
- 2Your foreign companyHolding company in company law, parent undertaking in the accounts. It meets the subsidiary test: a majority of the voting rights, or control of the board.
- 3The new local company, owned 100%Subsidiary, and wholly owned if it has no other member.
| Jurisdiction | Is the new company a subsidiary in law? | What the corporate owner changes |
|---|---|---|
| United Kingdom | Yes, under section 1159 | Wholly owned if there is no other member |
| Hong Kong | Yes, under sections 13 and 15 | The corporate shareholder goes on the controllers register |
| Singapore | Yes, under section 5 | The company cannot be an Exempt Private Company |
| United States (Delaware LLC) | No general definition read | Nothing in the state filing; a federal form applies |
United Kingdom. For a UK company owned from abroad, the definition applies whatever the holding company's country.
Singapore. Our company types guide lists what follows from a corporate shareholder:
- An Exempt Private Company has at most 20 shareholders, all individuals. One corporate shareholder removes that label.
- The resident director requirement stays, whoever owns the shares.
United States. The Delaware provisions we read do not use "parent" and "subsidiary" as categories.
- A Delaware LLC can be owned by a company, including a foreign one.
- Its certificate of formation names no member, so the owner does not appear in the state filing.
- Form 5472 is due from a US corporation that is 25% foreign-owned, and from a foreign-owned disregarded entity.
What the chain changes in the controller registers
Two thresholds are easy to confuse.
| Question | Threshold |
|---|---|
| Is company B a subsidiary of company A? | A majority of the voting rights, or control of the board |
| Is someone a registrable controller of company B? | More than 25% of the shares or voting rights |
The second question does not stop at the first company in the chain.
- Hong Kong. The controllers register covers direct or indirect holdings of more than 25%. A corporate shareholder above that line is entered too.
- United Kingdom. A person with significant control holds more than 25% of the shares or voting rights, or can appoint or remove a majority of the directors.
- Singapore. The register of registrable controllers uses the same line of more than 25%, and it is not open to the public.
The Hong Kong Companies Registry gives its own example: a British Virgin Islands company holds the shares, and both that company and the person behind it are entered.
Putting a company between you and your subsidiary does not take you off the registers. It adds a layer you have to document.
We did not read how the UK and Singapore registers trace ownership through a foreign company, so check before you file.
Before you add a layer, prepare four things:
- A chart of the chain, from the individuals at the top to the operating company.
- The share of capital and of votes held at each level.
- Who can appoint or remove directors at each level.
- Who updates each register when one level changes.
What a bank asks when the shareholder is a company
No published rule covers this, so read what follows as an expectation. Our banking guides for Hong Kong and Singapore describe the baseline:
- Hong Kong: identity and address documents for every director and beneficial owner.
- Singapore: passport and proof of address for every director, shareholder and beneficial owner, with certified copies for non-residents.
With a corporate shareholder, the people behind the company sit one level higher, so expect to be asked for:
- the holding company's own incorporation documents
- a chart of the chain up to the individuals
- identity documents for those individuals
Each bank sets its own list, so ask for it before you apply.
Tax: one fact, and what this article leaves out
This article describes no tax structure. How a group is taxed depends on the law of both countries and on advice from someone qualified in both.
One official fact shows why the word "subsidiary" settles nothing. IRAS says some foreign-owned investment holding companies "are generally not considered tax residents of Singapore". Three conditions apply:
- 50% or more of the shares are held by foreign companies or by individuals who are not Singapore citizens
- the test is applied at the level of the ultimate holding company
- the income is purely passive or foreign-sourced
Incorporation in Singapore does not settle residence.
The summary
| Question | Answer |
|---|---|
| Which terms does company law define? | Holding company and subsidiary, as a pair |
| Where does "parent" come from? | Accounting rules ("parent undertaking") and usage |
| Is "more than 50% of the shares" the test? | No. Voting rights and board control come first |
| What does wholly owned mean? | No member outside the holding company's side |
| Does a holding company hide the founder? | No. The controller registers look past it |
Frequently asked questions
What is the difference between a holding company and a parent company?
In UK and Hong Kong company law, none: "holding company" is the legal term for the controlling company. "Parent" comes from accounting rules and everyday use. The passive versus active distinction is business usage.
What is a subsidiary company?
It is a company controlled by another. Under the UK Companies Act 2006, that means the other company holds a majority of the voting rights, or is a member and controls the board.
Is a subsidiary a separate legal entity?
Yes. A subsidiary is a company in its own right, with its own members and directors. A branch is not: it is an extension of the foreign company.
What is a wholly owned subsidiary?
Under section 1159(2) of the UK Companies Act 2006, it is a company with no members other than its holding company, that company's wholly owned subsidiaries, or persons acting on their behalf.
Do you need more than 50% of the shares to have a subsidiary?
Not necessarily. The UK test counts voting rights and the right to appoint or remove most of the board. Hong Kong also accepts more than half of the issued share capital.
Can a company be both a holding company and a subsidiary?
Yes. The UK, Hong Kong and Singapore definitions all follow the chain: a controlled company can itself control another. The company at the bottom is a subsidiary of both.
Can an individual be a holding company?
No, on the definitions read here. They speak of companies and bodies corporate. A person who owns all the shares is a shareholder.
Can a foreign company own a Delaware LLC?
Yes. The certificate of formation names no member, so the owner does not appear in the state filing. A foreign-owned US entity falls within Form 5472 reporting.
Does owning through a holding company keep my name off the register?
No. Hong Kong counts direct or indirect holdings of more than 25%, and its Companies Registry shows a BVI company and the person behind it both entered.
Is a branch the same as a subsidiary?
No. Our Singapore guide describes a subsidiary as a separate company with ring-fenced liability, and a branch as an extension of the foreign parent, which stays fully liable.
