If you operate a company outside Hong Kong and want to establish a presence here, you have three main options. You can register your existing entity directly with the Companies Registry as a Non-Hong Kong Company (commonly called a branch office), incorporate a separate Hong Kong subsidiary, or set up a representative office for non-revenue activities.
Most foreign investors planning long-term operations choose a subsidiary because it provides liability protection and broader access to local incentives. The branch office route makes sense when you want your existing entity to operate in Hong Kong directly without setting up a new company.
This guide covers the branch office route. If you're still deciding between structures, the comparison table further down covers the trade-offs.
When a Branch Office Makes Sense
A Non-Hong Kong Company is registered under Part 16 of the Companies Ordinance (Cap. 622). Your overseas parent is the entity doing business in Hong Kong, holding the contracts, employing the staff, and carrying the liabilities directly. The Hong Kong "branch" is the same legal entity as your parent, recognized for operational purposes under Hong Kong law.
This structure works well when:
- You want a fast, lightweight presence in Hong Kong without the administrative overhead of incorporating a new company
- Your parent entity has the financial standing and reputation you want to leverage directly with Hong Kong customers
- You're testing a market and want a structure you can wind down without a full liquidation
- Your business model doesn't depend on government grants or incentives that require local incorporation
However, the branch office is not a preferred route when:
- You want to limit your parent's exposure to Hong Kong-specific liabilities
- You plan to access government grants, R&D incentives, or sector-specific schemes available only to locally incorporated companies
- You want to ring-fence Hong Kong operations financially or operationally from the rest of the group
- You expect to bring on local equity partners or raise local capital
For long-term, independent operations in Hong Kong, a subsidiary is generally the better fit. The branch route is most useful for established businesses extending an existing operation rather than building a new one from scratch.
Requirements for Overseas Company Registration in Hong Kong
Before you can register, your company must meet a set of legal and administrative requirements set by the Companies Registry. These ensure your foreign entity has a verifiable local presence and a designated point of contact for statutory communications in Hong Kong. You will need to prepare the following:
- A physical Hong Kong address for receiving legal notices and government correspondence. A virtual office address is acceptable, provided it is a real physical location. A P.O. box does not qualify.
- At least one local authorized representative (which can be an individual or corporate entity) must be appointed to handle legal compliance and communications with authorities
- Details of directors, shareholders, the company secretary, and officers authorized to act on behalf of the company must be submitted.
- Certified copy of your Certificate of Incorporation or equivalent from your home jurisdiction.
- Certified copy of your Articles of Association, charter, statutes, or constitutional documents.
- Certified copy of your latest published financial statements. This requirement is waived if your company has been incorporated for less than 18 months and has not yet published accounts.
- Completed Form NN1 (Application for Registration as a Non-Hong Kong Company).
Documents not in English or Chinese must be certified and legalized before submission. Whether you need an apostille or consular legalisation depends on whether your home country is a signatory to the Hague Apostille Convention. Emerhub can advise on the correct process and handle legalization on your behalf.
How to Register an Overseas (Non-Hong Kong) Company in Hong Kong
Under Part 16 of the Companies Ordinance (Cap. 622), all foreign companies must register with the Hong Kong Companies Registry before establishing a place of business here. This includes overseas companies (branch offices).
The Companies Registry typically processes complete applications within 1–3 days, provided your documentation is complete. The entire process, including document attestation, obtaining your Business Registration Certificate, and setting up a corporate bank account, however, may take three to six weeks, depending on your sector.
Step 1: File Your Application with the Companies Registry
Submit Form NN1 together with your certified company documents and registration fee to the Companies Registry. You can file electronically via the e-Services Portal (HKD 1,545) or in hard copy (HKD 1,720).
Once approved, the Registry issues your Certificate of Registration of a Non-Hong Kong Company. This confirms that your foreign entity is legally recognised to establish a place of business in Hong Kong.
Incomplete or unattested documents are the most common cause of delay, so make sure all your documents are authenticated before submission.
Emerhub can manage your Form NN1 submission and liaise with the Companies Registry on your behalf.
Step 2: Apply for the Business Registration Certificate (BRC)
Once the Companies Registry approves your application, they will typically notify the Inland Revenue Department (IRD) on your behalf. However, you must apply for the BRC within one month of commencing business activities in Hong Kong.
- Costs (Effective April 2026): A one-year certificate costs HKD 2,350, while a three-year certificate is available for HKD 6,170. These must be renewed before expiry to maintain good standing.
- Tax Registration: Obtaining the BRC automatically fulfills your initial tax registration. The IRD registers the branch for Profits Tax at this stage. While your first Profits Tax Return usually arrives 18 months after registration, you are legally required to notify the IRD in writing if your company generates taxable profits before that return is issued.
Holding a BRC provides the legal standing needed to sign commercial leases, establish local utility accounts, and execute B2B service contracts. It also authorizes non-regulated activities such as general trading, consulting, and software services. You can also start hiring and issuing employment contracts. However, most companies finalize their banking and licensing setup before commencing active hiring or payroll.
Step 3: Secure Sector-Specific Licenses (If Applicable)
Hong Kong doesn't restrict which sectors can register as a Non-Hong Kong Company. Trading, consulting, technology, and e-commerce companies can all register without sector approval. However, regulated industries require additional licensing before commencing operations. Common sectors include:
- Financial Services: Requires licensing from the Securities and Futures Commission (SFC) or Hong Kong Monetary Authority (HKMA).
- Education: Requires registration with the Education Bureau.
- Travel & Tourism: Requires a license from the Travel Industry Authority (TIA).
- Food & Beverage: Requires health and liquor licenses from the FEHD.
- Employment Agencies: Requires licensing from the Labour Department.
These applications require your BRC as a supporting document and run on their own timelines, independent of your Companies Registry filing.
Step 4: Open a Corporate Bank Account
Opening a bank account is the final step toward full operations. Because this is a commercial process, banks require your primary registration documents (Step 1 and Step 2) before they will begin their review.
- General Timeline: You should expect this to take between 4 to 8 weeks. However, complex corporate structures or regulated industries may face a due diligence process lasting up to 4 months.
- Bank Requirements: Local banks will perform intensive "Know Your Customer" (KYC) checks. In many cases, directors or authorized signatories may be required to visit Hong Kong in person for a formal interview.

Step 5: MPF Registration and Employment Compliance
If you plan to hire employees in Hong Kong, MPF registration is mandatory. The Mandatory Provident Fund (MPF) requires employers to enroll all regular employees aged 18 to 65 into an approved MPF scheme. Both employer and employee contribute 5% of the employee's relevant income, capped at HKD 1,500 per month each.
Other employment obligations include:
- Employer's Return of Remuneration (Form IR56B) filed annually with the IRD
- Employees' Compensation Insurance (mandatory under the Employees' Compensation Ordinance)
- Notification to IRD when hiring or terminating employees
Alternative Structures for Foreign Companies in Hong Kong
A Non-Hong Kong Company (branch office) is the most direct route into Hong Kong, but it is not your only option. There are two other structures available, depending on how much operational presence and independence you need. Here’s how they compare:
| Feature | Branch Office (Non-HK Company) | Subsidiary (Private Limited Company) | Representative Office (RO) |
|---|---|---|---|
| Legal Status | Extension of parent; incorporated overseas | Separate legal entity; incorporated in Hong Kong | Extension of parent; incorporated overseas |
| Licensing Authority | Companies Registry | Companies Registry | Inland Revenue Department (IRD) only |
| Parent Liability | Full | Limited to capital contributed | Full |
| Revenue Generation | Permitted across all registered business activities | Permitted across all registered business activities | Not permitted |
| Permitted Activities | Full commercial operations under parent company scope | Full commercial operations under its own registered scope | Market research, liaison, and promotional activities only |
| Tax Filing | Filed under parent company | Independent tax filing | No taxable activity |
| Exit Process | Deregistration with Companies Registry | Full liquidation required | Deregistration with IRD |
| Best For | Extending existing operations under the parent's name | Long-term growth or operational independence from the parent | Exploring the market before committing to a full registration |
The right structure depends on what you want your Hong Kong presence to do. If you want a minimal footprint to explore the market before committing, a representative office keeps your setup light. It registers only with the IRD and carries no revenue permissions or Companies Registry obligations.
If you're planning long-term, independent operations, a subsidiary. (private limited company) gives you more room. As a locally incorporated entity, it can qualify for government grants, incentives, and access double tax treaty benefits that are generally not available to branch offices. The trade-off, however, is a more involved setup process and longer operational timeline.
One point worth noting: unlike many other jurisdictions, Hong Kong places no sector restrictions on branch office registration. Any foreign company in trading, consulting, or e-commerce can register as a Non-Hong Kong Company. The one constraint is that your branch must operate within the same business scope as your parent.

Ongoing Compliance Obligations
Once registered, a Non-Hong Kong Company has continuous obligations with both the Companies Registry and the IRD. Missing these deadlines can result in financial penalties or deregistration, so it pays to build them into your compliance calendar from day one.
- Annual Return (Form NN3) filed with the Companies Registry within 42 days of each registration anniversary
- Profits Tax Return filed annually with the IRD (first return typically issued 18 months after registration)
- BRC renewal before each expiry
- Notification of changes to authorized representatives, directors, secretaries, or registered address within prescribed timelines
- Maintenance of a registered office in Hong Kong throughout the operating period
- Annual financial statement submission if your parent's published accounts in its home jurisdiction trigger this requirement

Frequently asked questions
What is the difference between registering a Non-Hong Kong Company and incorporating a subsidiary?
A Non-Hong Kong Company (branch office) means your foreign entity operates in Hong Kong directly. There is no new company. Your parent holds the contracts, employs the staff, and carries the liabilities. A subsidiary is a separate Hong Kong company owned by your parent. It has its own legal identity and tax obligations, which means your parent company's exposure is limited to its capital contribution.
Can an overseas company use a virtual office as its Hong Kong registered address?
You can use a virtual office for your overseas company in Hong Kong, provided it is a physical location in Hong Kong capable of receiving legal notices. A P.O. box does not meet the requirement. Most corporate services providers, including Emerhub, offer registered address services that help you satisfy this obligation.
Is an overseas company subject to Hong Kong Profits Tax?
Your overseas company is subject to the profits tax but only on profits derived from Hong Kong. Income earned entirely outside Hong Kong is not taxed locally. If your company generates revenue from both Hong Kong and overseas sources, you will need to maintain separate records to demonstrate which portion is offshore. For Non-Hong Kong Companies, the IRD may also request audited accounts from the parent company to verify the Hong Kong branch's profits tax return.
How long does the registration process take for an overseas company in Hong Kong?
The Companies Registry typically processes complete applications within one to two weeks. The full process, including document authentication, your BRC, and corporate bank account setup, takes four to eight weeks. Bank KYC checks can extend the timeline further depending on the complexity of your ownership structure. The main variable is how quickly you can authenticate your home jurisdiction documents. Jurisdictions requiring consular legalisation rather than an apostille can add several weeks to the timeline.
Can I register an overseas company in Hong Kong remotely?
The Companies Registry accepts electronic filings and does not require directors or shareholders to be present in Hong Kong. However, some banks may require in-person meetings with directors as part of their KYC process. A local corporate services provider like Emerhub can manage the Registry filings on your behalf and advise on banks that are more accommodating of remote applicants.
