What’s the difference between a subsidiary, branch and representative office in Hong Kong?
A subsidiary is a separate Hong Kong company that limits the parent’s liability and can trade freely. A branch is the same foreign company operating in Hong Kong — it can trade, but the parent bears full liability and must register as a registered non-Hong Kong company. A representative office cannot do business or earn profit; it is only for liaison, promotion and market research. Most foreign businesses that intend to trade choose a subsidiary.
Which structure should a foreign business choose?
The decision usually comes down to three questions. How much liability protection do you want? Will you actually generate revenue in Hong Kong? And how much set-up and compliance are you willing to take on? A subsidiary gives the cleanest separation and the most flexibility. A branch sits closer to the parent but exposes it. A representative office is a low-commitment way to test the water, with strict limits on what it can do.
Comparison table: subsidiary vs branch vs representative office
| Feature | Subsidiary (HK private company) | Branch (registered non-HK company) | Representative office |
|---|---|---|---|
| Legal status | Separate legal entity from the parent | Not separate — part of the foreign company | No separate legal status; not a trading entity |
| Can it trade / earn profit? | Yes — full business activities | Yes — but generally limited to the parent’s business activities | No — liaison, promotion and market research only |
| Parent company liability | Generally limited to the subsidiary; parent shielded | Parent fully liable for the branch’s debts and obligations | Parent liable, but the office cannot incur trading liabilities |
| Primary registration | Incorporate under Companies Ordinance (Cap. 622) with the Companies Registry | Register as a non-Hong Kong company (Companies Ordinance Part 16) within one month of establishing a place of business (Form NN1) | Business registration with the Inland Revenue Department |
| Business registration (IRD) | Required | Required | Required |
| Activity scope | Can be the same as, or different from, the parent | Generally same line of business as the parent | Strictly non-revenue activities only |
| Hong Kong profits tax | Taxed on profits arising in/derived from Hong Kong | Taxed on profits arising in/derived from Hong Kong | Not subject to profits tax (no Hong Kong profits) |
| Typical use | Long-term, revenue-generating Hong Kong operation | Extension of an existing overseas business into Hong Kong | Testing the market, liaison before committing |
| Relative set-up effort | Higher (new company + ongoing compliance) | Moderate | Lowest |
Subsidiary in Hong Kong: how it works
A subsidiary is a Hong Kong company, usually a private company limited by shares, incorporated under the Companies Ordinance (Cap. 622) and owned wholly or partly by the foreign parent. Because it is a separate legal entity, it generally insulates the parent from the subsidiary’s debts and liabilities. That separation is the main reason most foreign businesses choose it. The subsidiary can trade, sign contracts, hire staff, and carry on activities beyond the parent’s own business. In return, it carries the full compliance load of a Hong Kong company: a registered office, a company secretary, at least one director who is a natural person, annual returns, and a significant controllers register.
Branch (registered non-Hong Kong company): how it works
A branch is not a new company. It is the same foreign company operating in Hong Kong. When a non-Hong Kong company establishes a place of business here, it must register as a registered non-Hong Kong company with the Companies Registry under Part 16 of the Companies Ordinance, within one month of establishing that place of business (using Form NN1). The consequence that matters is liability: because the branch is not separate, the foreign parent is fully responsible for the branch’s debts and obligations in Hong Kong. A branch is usually limited to the same kind of business the parent carries on.
Representative office: how it works
A representative office is the lightest-touch option, suited to a business that wants a Hong Kong presence before committing to trade. It can carry out non-revenue activities only: liaison, promotion, and market research on behalf of the parent. It cannot enter into business contracts in its own name, issue invoices, or otherwise earn profit in Hong Kong. Typically it registers for business registration with the Inland Revenue Department. Because it earns no Hong Kong profits, it is generally not subject to profits tax. If it starts trading in substance, the authorities may treat it as a branch or permanent establishment, so the limits matter.
How is each structure taxed in Hong Kong?
Hong Kong taxes profits that arise in or are derived from Hong Kong. Both a subsidiary and a branch are generally subject to profits tax on their Hong Kong-sourced profits. A representative office, which by definition earns no Hong Kong profits, generally falls outside profits tax. Hong Kong’s two-tiered profits tax regime applies a lower rate to an initial band of assessable profits and the standard rate above it: for corporations, 8.25% on the first HK$2 million of assessable profits and 16.5% above that (7.5% / 15% for unincorporated businesses). The lower tier is not automatic for groups: where a business has connected entities, only one nominated entity can enjoy the two-tiered rates in a given year of assessment, and the election is made in the profits tax return. Always confirm current rates, the threshold and the connected-entity rules with the Inland Revenue Department before relying on figures.

Frequently asked questions
Is a subsidiary or a branch better for a foreign company in Hong Kong? For most businesses that intend to trade and want to protect the parent, a subsidiary is preferable because it is a separate legal entity with limited liability. A branch can be simpler as an extension of an existing business, but the parent remains fully liable for its Hong Kong debts. The right answer depends on liability appetite, tax position and long-term plans.
Can a representative office sign contracts or make sales in Hong Kong? No. A representative office is limited to non-revenue activities such as liaison, promotion and market research. It cannot enter into business contracts in its own name, issue invoices or earn profit. If it does, it risks being treated as a branch or permanent establishment.
Does a branch office protect the parent company from liability? No. A branch is not a separate legal entity — it is the same foreign company operating in Hong Kong — so the parent is fully responsible for the branch’s liabilities. If liability protection is a priority, a subsidiary is usually the better structure.
What is a “registered non-Hong Kong company”? It is the status a foreign company takes when it establishes a place of business in Hong Kong and registers with the Companies Registry under Part 16 of the Companies Ordinance, within one month of establishing that place of business. In practice, this is how a “branch” is set up. The company files prescribed particulars (Form NN1) and appoints an authorised representative in Hong Kong.
Do all three structures need a business registration certificate? Generally, a business carrying on in Hong Kong must register under the Business Registration Ordinance (Cap. 310) with the Inland Revenue Department within one month of commencing business, and this applies to subsidiaries, branches and representative offices alike. The form of company registration with the Companies Registry differs, but business registration is a common requirement.
Can I convert a representative office into a subsidiary or branch later? A representative office cannot simply “convert”, but a business commonly starts with a representative office to test the market, then sets up a subsidiary or registers a branch when it is ready to trade. We can plan the transition so it is clean from a liability and tax standpoint.
How long does it take to set up each structure? A subsidiary incorporation and a branch registration both go through the Companies Registry, while a representative office mainly needs business registration. A straightforward online incorporation can be completed within about one hour of a complete electronic submission, though timing varies with documentation and KYC checks. We give you a realistic estimate for your facts.
