A foreign company has three ways to operate here: form a subsidiary, register a branch, or open a representative office. The Hong Kong branch vs subsidiary choice comes down to one question: should the parent company be directly liable for what happens in Hong Kong?
A subsidiary is a separate company with limited liability. A branch is the parent itself, doing business here. A representative office can only do liaison and market research, and it cannot earn money.
Profits tax is the same for a branch and a subsidiary. Almost everything else differs: liability, setup, yearly filings, bank access and treaty benefits.
The Three Structures at a Glance

|---|---|---|---|
Legal status | Separate Hong Kong company | Part of the foreign parent | Part of the foreign parent |
Parent's liability | Limited to its investment | Unlimited for branch debts | Unlimited |
Can earn revenue and sign contracts | Yes | Yes | No |
Registered with | Companies Registry and IRD | Companies Registry (as a non-Hong Kong company) and IRD | IRD Business Registration Office only |
Company secretary | Required | Not required | Not required |
Hong Kong statutory audit | Required every year | Not required for the branch itself | Not required |
Profits tax rate | 8.25% / 16.5% | 8.25% / 16.5% | Not taxable if it earns nothing |
Access to Hong Kong tax treaties | Generally yes | Generally no | No |
Name | Its own name | Must use the parent's name | Parent's name |
What Is a Hong Kong Subsidiary?
A Hong Kong subsidiary is an ordinary private company limited by shares, wholly or partly owned by the foreign parent. Because it is a separate legal person, its debts stay with it. The parent risks only the capital it put in, unless it gives guarantees.
The subsidiary needs at least one director who is an individual, a company secretary based in Hong Kong, a registered office, and annual audited accounts. It files a yearly return with the Companies Registry and keeps a Significant Controllers Register. Our guide to the Hong Kong company secretary role covers the secretary requirement in detail.
Incorporation costs HK$1,545 when filed electronically, plus the business registration fee.
What Is a Branch of a Non-Hong Kong Company?
A branch is the foreign parent itself, registered to do business in Hong Kong. Under Part 16 of the Companies Ordinance (Cap. 622), a foreign company that establishes a place of business in Hong Kong must register as a non-Hong Kong company within one month. Missing that deadline is an offense, with fines for the company and its officers.
Registration uses Form NN1, filed with the parent's certified constitution, certificate of incorporation, details of its directors, and its latest accounts where its home law requires them to be published. Documents not in English or Chinese need certified translations. The filing fee is HK1,720 on paper, according to the Companies Registry fee schedule.
A branch must appoint at least one authorized representative in Hong Kong. This is a person living here, or a qualifying Hong Kong firm, who accepts official documents on the company's behalf.
After registration, the branch files its own annual return, Form NN3, within 42 days after each anniversary of its Hong Kong registration. Changes to the parent's directors, name or constitution must also be reported, generally within one month.
What Is a Representative Office?
A representative office in Hong Kong is the lightest option. It registers with the Business Registration Office of the Inland Revenue Department, not with the Companies Registry.
It may:
• promote the parent's products and services
• do market research
• act as a contact point for customers and suppliers in the region
It may not trade, sign sales contracts in Hong Kong, issue invoices, or earn revenue here. Any contract must be signed by the foreign parent.
This structure fits a company testing the market before committing. It is usually meant to be temporary.
When a representative office becomes a branch
This is the gap most guides skip. The line is drawn by what the office does, not by what you call it. If staff in Hong Kong start negotiating and concluding contracts, taking orders or collecting payments, the parent has probably established a place of business. At that point it must register as a non-Hong Kong company within one month, and the activity may create a profits tax liability.
Review the office's actual activities every quarter. Calling it a "rep office" will not help if it behaves like a branch.

How Are They Taxed?
Hong Kong taxes by source, not by legal form. Profits of a branch or a subsidiary that arise in Hong Kong are taxed at the same two-tier rates: 8.25% on the first HK$2 million for a corporation and 16.5% above that. A representative office that earns nothing here generally has no profits tax liability, though it still holds a business registration certificate.
The difference is treaty access. A subsidiary incorporated in Hong Kong can usually apply for a Hong Kong tax residency certificate and claim treaty benefits when it receives payments from countries with a tax agreement. A branch is part of a foreign company, so it is generally not a Hong Kong resident for treaty purposes, unless the parent itself is managed or controlled from Hong Kong.
Profit repatriation is simple either way. Hong Kong charges no withholding tax on dividends paid by a subsidiary, and branch profits can be remitted to the parent without Hong Kong tax.
Hong Kong Branch vs Subsidiary: Banking and Practical Differences
The legal comparison is only half the story. Day to day, these points matter more:
Bank accounts. A subsidiary opens accounts in its own name with Hong Kong documents. A branch's account is in the parent's name, and banks review the whole foreign parent, its owners and its accounts. For a parent in a higher-risk country, that can be much harder.
Contracts and invoices. Hong Kong customers and suppliers are generally more comfortable contracting with a local company. A branch invoices in the parent's foreign name.
Hiring and visas. Both can employ staff and sponsor work visas, but a subsidiary is simpler to present to the Immigration Department as a local employer.
Selling or restructuring. Shares in a subsidiary can be sold or transferred. Stamp duty applies at 0.1% on each side of a transfer of Hong Kong shares. A branch cannot be sold separately from the parent.
Closing. A subsidiary is closed by deregistration or winding up. A branch is closed by filing a cessation notice with the Companies Registry.
Which Should You Choose?
Our position: for most foreign companies, and for almost all founder-led businesses from Russia and the CIS, a subsidiary is the better choice. Limited liability, cleaner banking and treaty access usually outweigh the extra cost of a secretary and an annual audit.
Choose a branch when:
• the parent is a large, well-documented company that banks will accept easily
• you want Hong Kong profits and losses inside the parent's own accounts
• the parent's home rules make a branch more tax-efficient than a subsidiary
Choose a representative office when:
• you only need market research, promotion or a liaison point
• you do not plan to sell or sign contracts in Hong Kong yet
• you want to test the market before forming a company
If you already have an operating company abroad and want to move it rather than open a second entity, a third route exists. Hong Kong has allowed foreign companies to re-domicile here since 2025. See our guide on Hong Kong re-domiciliation.
Can You Switch Structures Later?
Yes, but not by flipping a switch. Each structure is a separate registration, so moving from one to another means opening the new one and closing the old.
The common path is a representative office in Hong Kong first, then a subsidiary once sales begin. That move is straightforward: incorporate the subsidiary, move staff and lease agreements across, then cancel the representative office's business registration.
Converting a branch into a subsidiary takes more care. The new company must take over contracts, employees, bank accounts and assets from the parent. Customers have to be told the contracting party has changed, and some contracts need their consent. Transfers of assets or a business can also carry tax consequences in Hong Kong and in the parent's home country.
So choose with the next two or three years in mind, rather than the first month alone. A switch you can avoid is one you never pay for. If you expect to sell in Hong Kong soon, starting with a subsidiary avoids a migration later.
Cost and Time Compared
Item | Subsidiary | Branch | Representative office |
|---|---|---|---|
Companies Registry filing | HK$1,545 electronic | HK$1,545 electronic | None |
Business registration (1 year) | HK$2,350 | HK$2,350 | Business registration fee applies |
Ongoing secretary | Yes | No | No |
Annual Hong Kong audit | Yes | No statutory audit for the branch | No |
Typical setup time once documents are ready | Days | Longer, because parent documents must be certified and translated | Days |
The branch often looks cheaper on paper because it avoids a secretary and a statutory audit. In practice, certifying and translating the parent's documents, and the bank's review of the whole parent, can cost more time than forming a subsidiary.
Making the Hong Kong Branch vs Subsidiary Decision
Start with liability and banking, not with fees. If the parent should be shielded from Hong Kong risks, or if the parent would struggle with a bank review, form a subsidiary. If the parent is large, low-risk and wants Hong Kong results on its own books, a branch can work. If you are only exploring, a representative office buys time, provided its activities stay within the limits.

Frequently Asked Questions
Does a branch in Hong Kong need an audit?
Hong Kong law does not require a separate statutory audit of a branch, unlike a Hong Kong subsidiary, which must be audited every year. A branch still files profits tax returns supported by accounts for its Hong Kong business, and generally delivers the parent's financial statements with its annual return.
Can a representative office sign contracts in Hong Kong?
No. A representative office can promote the parent, do market research and act as a contact point, but it cannot conclude sales contracts, issue invoices or earn revenue in Hong Kong. If it starts doing those things, the parent likely needs to register as a non-Hong Kong company within one month.
Which pays less tax, a branch or a subsidiary?
Neither, in Hong Kong. Both pay profits tax on Hong Kong-sourced profits at 8.25% on the first HK$2 million and 16.5% above. The difference usually comes from the parent's home country, where a branch's profits and a subsidiary's dividends may be taxed differently under local rules and treaties.
How long does it take to register a branch in Hong Kong?
The Companies Registry review itself is usually quick once Form NN1 and the documents are complete. Most of the time goes into preparing the parent's documents: obtaining certified copies, translating them where needed, and appointing an authorized representative. Plan for a few weeks from start to finish.
Can a foreign company own 100% of a Hong Kong subsidiary?
Yes. A foreign company can own all the shares in a Hong Kong subsidiary, and there is no local shareholder requirement. The subsidiary must still have at least one director who is an individual, a company secretary based in Hong Kong, and a Hong Kong registered office address.
