Every Hong Kong company must have a registered office address from the day it is incorporated. This is a legal requirement under the Companies Ordinance. At the same time, most companies also use a business address for day-to-day operations and customer communications.
These two addresses serve different purposes, and understanding how they differ is important for compliance, privacy, and smooth business operations — especially for tech founders running remote or digital-first companies.
What is a Registered Office Address in Hong Kong?
A registered office address is the official legal address of your Hong Kong limited company. It is the address recorded with the Companies Registry and serves as the primary point of contact for official government and legal correspondence.
Under the Companies Ordinance (Cap. 622), every company incorporated in Hong Kong must maintain a registered office address in Hong Kong from the date of incorporation. This is not optional. The address must be a physical location in Hong Kong. P.O. boxes and unlicensed mail-forwarding services are not accepted.
The registered office address is publicly available. Anyone can search for it through the Companies Registry’s online portal. This public nature is one reason many founders prefer not to use their residential address for this purpose.
Key characteristics
- It is a mandatory legal requirement for all Hong Kong companies.
- It must be a physical street address in Hong Kong.
- It appears on public company records and is searchable.
- Official documents from the Companies Registry, Inland Revenue Department, and courts are sent here.
- Any change must be reported within 15 days using Form NR1.
What is a Business Address in Hong Kong?
A business address (sometimes called the correspondence address or principal place of business) is where your company carries out its everyday operations. This is the address you typically use when communicating with customers, suppliers, and partners.
Unlike the registered office address, a business address is not a strict statutory requirement in the same formal sense. It is usually declared when obtaining your Business Registration Certificate from the Inland Revenue Department. Companies can have one or multiple business addresses depending on their operational model.
For many tech startups with remote or distributed teams, the business address might be a co-working space, a home office, or aligned with the registered office. The business address tends to be more flexible.
Key characteristics
- It reflects where your company actually operates or receives commercial communications.
- It is used for day-to-day business interactions.
- It is generally not publicly searchable on the Companies Register.
- Changes are notified to the Inland Revenue Department.
- A company can have multiple business addresses if needed.
Key Differences Between the Two Addresses
Understanding the practical differences helps founders make informed decisions.
| Aspect | Registered Office | Business Address |
|---|---|---|
| Legal status | Mandatory under Companies Ordinance | Declared for Business Registration |
| Purpose | Official government & legal correspondence | Day-to-day operations & commercial use |
| Public visibility | Publicly searchable on Companies Registry | Not automatically public |
| Change notification | Form NR1, within 15 days | Form IRC3111A, within 1 month |
| Government body | Companies Registry | Inland Revenue Department |
| Quantity | Exactly one | One or more |
Can the Registered Office and Business Address Be the Same?
Yes, it is completely legal and very common for companies, especially in the early stages, to use the same address for both purposes. Many founders begin this way to keep administration simple and costs lower.
However, there are situations where separating the two addresses can be advantageous:

Common Mistakes Tech Founders Make
Several recurring issues appear when founders do not fully understand the distinction between these addresses.
How to Choose the Right Setup for Your Tech Startup
There is no single correct approach. The best setup depends on your stage, team structure, privacy preferences, and growth plans.
Key questions to ask yourself
- Do I want my operational or residential location to be publicly visible?
- How important is reliable digital access to official mail and documents?
- Am I planning to raise investment in the near future?
- How frequently might my team location or operational needs change?
- What is my budget for address-related services?
Key Takeaways
- A registered office address is a mandatory legal requirement; a business address is operational.
- The registered office is publicly searchable; the business address generally is not.
- Using the same address for both is common and perfectly legal in the early stages.
- Privacy-conscious founders should use a licensed service provider rather than a home address.
- Always ensure your registered office provider holds a valid TCSP licence.
- When changing address, remember to notify the correct government body within the required timeframe.
