Non-HK Company Registration in Hong Kong | Deep Blue CPA

At Deep Blue CPA Limited, we provide professional non-Hong Kong company registration services for overseas corporations seeking to establish a presence in Hong Kong. Governed by Part 16 of the Hong Kong Companies Ordinance (Cap. 622), any company incorporated outside Hong Kong that establishes a place of business in the city must register with the Companies Registry. Our team guides foreign businesses through every step of the compliance process — from document certification to filing and ongoing statutory obligations.

Whether you are a multinational corporation opening a regional office or a growing enterprise exploring the Hong Kong market, we help you choose the right structure and ensure full regulatory compliance. Our integrated services also cover annual return filing, tax compliance, and deregistration when your Hong Kong presence is no longer required.

What is a Non-Hong Kong Company Registration?

A non-Hong Kong company (also referred to as an overseas or foreign company) is a company incorporated outside Hong Kong that establishes a place of business within Hong Kong. Under Section 776 of the Companies Ordinance (Cap. 622), the company must apply to the Companies Registry for registration as a registered non-Hong Kong company within one month of establishing a place of business in Hong Kong.

A "place of business" includes a share transfer or share registration office, a factory, a warehouse, or any place through which the company carries on business. Simply having a mailing address or a telephone listing does not necessarily constitute a place of business — but operating from a physical office or regularly meeting clients in Hong Kong likely triggers the registration requirement.

This registration is also commonly referred to as branch registration, although it is distinct from incorporating a separate subsidiary company. The key distinction is that a registered non-Hong Kong company remains a single legal entity — the branch is not a separate legal personality from its overseas parent.

When is it Needed?

Foreign businesses typically need to register under Part 16 in the following scenarios:

• Branch office — The overseas company wishes to operate in Hong Kong under its existing corporate identity without incorporating a separate subsidiary.
• Service or liaison office — The company needs a physical presence in Hong Kong for client liaison, marketing, or administrative support.
• Regional headquarters — A multinational group establishes a Hong Kong office to oversee Asia-Pacific operations while keeping the parent company outside Hong Kong.
• Regulatory requirement — Certain regulated activities or contracts may require a registered place of business in Hong Kong.

Before deciding to register as a non-Hong Kong company, it is important to evaluate whether a Hong Kong incorporated subsidiary may be more appropriate. A subsidiary offers limited liability protection and is often the preferred structure for companies intending to trade actively in Hong Kong. We provide a detailed comparison below.

Requirements for Registration

To register as a non-Hong Kong company under Part 16, the following documents and information must be submitted to the Hong Kong Companies Registry:

• Certified copy of incorporation certificate — A certified true copy of the certificate of incorporation (or equivalent registration document) from the company's place of incorporation, together with a certified translation if not in English or Chinese.
• Certified copy of constitutional documents — The company's memorandum and articles of association (or equivalent constitutional documents), similarly certified and translated if necessary.
• Particulars of directors and company secretary — Full name, residential address, and identification details of each director and the company secretary. At least one director must be an individual. A corporate director is permitted if the company's home jurisdiction allows it.
• Particulars of authorised representative — The company must appoint at least one authorised representative resident in Hong Kong (an individual or a corporate body) to accept service of process and notices on behalf of the company.
• Registered office address in Hong Kong — A physical Hong Kong address (not a PO Box) where legal documents may be served.
• Statement of principal place of business in Hong Kong — The address of the principal office in Hong Kong.

All documents not in English or Chinese must be accompanied by a certified translation. Documents issued by the home jurisdiction's authorities must typically be notarised or apostilled (depending on whether the home country is a party to the Hague Apostille Convention). Our team can coordinate the certification and legalisation process through our notarisation and apostille services.

Process and Timeline

The registration process for a non-Hong Kong company typically takes 4 to 6 weeks from the date all certified documents are received. The timeline depends on several factors:

1. Document preparation (1–2 weeks) — Obtaining certified copies of incorporation documents from the home jurisdiction, arranging notarisation or apostille, and preparing certified translations where needed.
2. Form submission (1–2 days) — Completing and submitting the prescribed forms (Form NN1 — Application by a non-Hong Kong company for registration) together with supporting documents and the registration fee.
3. Companies Registry review (3–4 weeks) — The Registrar reviews the application and supporting documents. If documents are in order, a Certificate of Registration and a Business Registration Certificate are issued. The Registrar may raise queries or request additional information, which can extend the timeline.

Expedited processing is not available for Part 16 registrations. Each application is subject to review by the Registrar, and any deficiencies in the certified documents must be rectified before registration can proceed.

Branch vs Subsidiary: Which Structure is Right for You?

When entering the Hong Kong market, foreign businesses must decide whether to register as a non-Hong Kong company (branch) or incorporate a separate Hong Kong subsidiary. Both options have advantages and disadvantages that should be carefully evaluated:

Branch (Non-Hong Kong Company Registration)

• No separate legal entity — The branch is part of the overseas company; the parent is fully liable for all branch obligations.
• Simpler setup — Registration under Part 16 requires fewer steps than full incorporation, though document certification from the home jurisdiction adds complexity.
• No share capital requirement — Unlike a HK subsidiary, there is no minimum issued share capital requirement for a branch.
• Global profit reporting — The branch must file the overseas company's worldwide financial statements in Hong Kong, which may reveal the global financial position.
• Stamp duty — No stamp duty on share capital (since there are no shares issued).

Subsidiary (Hong Kong Incorporated Company)

• Separate legal entity — Liability is limited to the subsidiary's assets; the overseas parent is protected.
• Full incorporation — A wholly separate Hong Kong company with its own directors, shareholders, and company secretary.
• Local financial reporting — Only the subsidiary's Hong Kong operations must be reported in its audited accounts, not the parent's worldwide results.
• More credible — A locally incorporated company is often preferred by local banks, suppliers, and customers.
• Share capital flexibility — Shares can be issued to attract local investors or employees.

In most cases, a Hong Kong incorporated subsidiary is the preferred choice for businesses that intend to trade actively and carry ongoing operations. The branch structure is more commonly used for liaison offices, regional coordination centres, or when the overseas company wishes to maintain a unified corporate identity. We recommend discussing your specific circumstances with our advisors to determine the optimal structure.

Ongoing Obligations

Once registered, a non-Hong Kong company must comply with ongoing statutory obligations under the Companies Ordinance:

• Annual return — File an annual return (Form NN3) with the Companies Registry within 42 days after the anniversary of registration. The annual return confirms the company's registered details and must be accompanied by the prescribed fee.
• Audited financial statements — Deliver a copy of the company's audited financial statements (covering the overseas company's worldwide operations) together with a branch-specific balance sheet to the Companies Registry within the prescribed period after the financial year-end. The accounts must be audited by a practising certified public accountant registered under the Professional Accountants Ordinance (Cap. 122).
• Profits Tax Return — File an annual Profits Tax Return with the Inland Revenue Department. The branch is subject to Hong Kong profits tax on profits arising in or derived from Hong Kong at the standard corporate tax rate (16.5%).
• Change notifications — Notify the Companies Registry within one month of any changes to the company's directors, company secretary, authorised representative, registered office address, principal place of business in Hong Kong, or constitutional documents.
• Business Registration — Renew the Business Registration Certificate annually with the Inland Revenue Department.

Failure to comply with these obligations can result in late filing penalties, prosecution, and potential deregistration of the non-Hong Kong company. Our corporate services team can manage all ongoing compliance requirements on your behalf.

Tax Treatment of Non-Hong Kong Companies

A registered non-Hong Kong company (branch) is subject to Hong Kong profits tax on profits arising in or derived from Hong Kong. The territorial principle of Hong Kong taxation applies equally to branches and subsidiaries — only Hong Kong-source profits are taxable.

Key tax considerations for branch operations:

• Profits tax rate — 16.5% on assessable profits (standard corporate rate). Unlike subsidiaries, branches are not eligible for the two-tiered profits tax rate (8.25% on the first HK$2 million) unless the overseas parent company does not have another associated entity in Hong Kong claiming the reduced rate.
• Head office expenses — A portion of head office administrative expenses may be deductible if they can be properly apportioned to the Hong Kong branch and supported by adequate documentation.
• Withholding tax — Royalties, interest, and certain payments to the overseas head office may be subject to withholding tax in Hong Kong.
• Double tax relief — If the overseas company's home jurisdiction has a double taxation agreement (DTA) with Hong Kong, the branch may benefit from reduced withholding tax rates or other treaty relief.

We work closely with our taxation team to ensure your branch's tax compliance is properly managed and optimised.

Frequently Asked Questions

Should I register a branch or a subsidiary in Hong Kong for my overseas company?

A branch is not a separate legal entity — it is an extension of the overseas company, and the parent company remains fully liable for all branch activities. A subsidiary is a separately incorporated Hong Kong company with its own legal personality, and the overseas parent's liability is limited to its shareholding. Branches are simpler to set up but offer no liability protection, while subsidiaries require full incorporation but provide limited liability and are generally preferred for ongoing trading operations.

Can I convert a registered non-Hong Kong company branch into a Hong Kong incorporated company later?

There is no direct conversion. You must wind up the branch under Part 16 and incorporate a new subsidiary. We can assist with both the branch deregistration and the new company incorporation.

Does a non-Hong Kong company registered in Hong Kong need audited accounts?

Yes. Non-HK companies must deliver audited worldwide financial statements to the Companies Registry annually.

What are the ongoing filing requirements for a registered non-HK company?

Non-HK companies must file an annual return within 42 days, audited financial statements, and a Profits Tax Return.

How long does it take to register a non-Hong Kong company in Hong Kong?

The registration process typically takes 4 to 6 weeks from submission of all required documents. The timeline depends on the completeness of the certified documents from the company's home jurisdiction and the current workload of the Companies Registry. Expedited processing is not available for Part 16 registrations as all documents must be reviewed by the Registrar.

Can a non-Hong Kong company register a representative office instead of a branch?

Hong Kong does not have a separate "representative office" designation under the Companies Ordinance. Any overseas company that establishes a place of business in Hong Kong — including an office, a share transfer or share registration office, or any place through which the company carries on business — must register under Part 16. If the company only has a liaison office that does not generate revenue or enter into contracts, professional advice should be sought to determine whether registration is required.
