When setting up a company in Hong Kong, founders frequently mix up two distinct concepts: the registered office and the business address. The confusion is understandable — both involve physical locations, and both appear on official documents. But they serve entirely different legal purposes, and conflating them can create real compliance problems down the line.
This guide explains exactly what each term means under Hong Kong law, what obligations come with each, and how to structure your setup correctly from day one.
What Is a Registered Office in Hong Kong?
A registered office is a formal legal requirement for every company incorporated in Hong Kong. It is defined and governed by Companies Ordinance Cap. 622, specifically Section 658.
Legal Definition and Requirements
Every company incorporated in Hong Kong must have a registered office within Hong Kong at all times. This is the address officially recorded with the Companies Registry and the Inland Revenue Department (IRD). The registered office is the address to which all official correspondence — including statutory notices, government communications, and legal documents — is directed.
Key requirements under Cap. 622:
- The address must be a physical location in Hong Kong — a PO Box is not acceptable.
- The address must be accessible and able to receive correspondence during normal business hours.
- It must be kept accurate at all times — any change must be reported to the Companies Registry using Form NR1 within 14 days of the change.
- The address is publicly searchable on the Companies Registry database.
Why the Registered Office Is Not Typically a Founder’s Home
Because the registered office is a matter of public record, many directors prefer not to use their private residential address. Anyone — competitors, solicitors, members of the public — can look up your registered office on the Companies Registry. Using a professional service provider’s address keeps your home address private while satisfying the legal requirement entirely.
For reference, HEVEA HK’s address at Unit G, 15/F, TAL Building, 49 Austin Road, Kowloon, serves as the registered office for companies in our portfolio. This address appears on the Companies Registry, receives all statutory correspondence, and is attended during business hours.
What Documents Arrive at Your Registered Office?
The registered office is the first point of contact for:
- Correspondence from the Companies Registry (annual return reminders, audit notices)
- Correspondence from the Inland Revenue Department (tax assessments, Business Registration Certificate renewal)
- Legal notices and court documents served on the company
- Correspondence from regulatory authorities
What Is a Business Address?
A business address is where your company actually operates, meets clients, or conducts day-to-day activities. It appears on your invoices, website, business cards, and marketing materials.
Is a Business Address Legally Required?
Under Cap. 622, there is no separate legal requirement to register a “business address” distinct from your registered office. However, if your company has a physical place of operation — whether a rented office, coworking desk, or retail unit — that address will naturally function as your business address.
In practice, many lean HK companies, especially those operated remotely or internationally, have no separate business premises. Their registered office and their operational point of contact are effectively the same thing, managed through their registered office service provider.
When Do the Two Addresses Differ?
The two addresses diverge most commonly when a company has staff or premises at a location separate from its registered office. For example: a trading company might use a registered office service in Kowloon for compliance purposes, while operating out of a coworking space in Central. Both addresses are valid and serve their respective purposes.
Why Use a Professional Registered Office Service?
Using a professional registered office service provider — rather than a director’s home or a serviced office — offers several practical advantages.
Privacy and Public Record
Your registered office address is public. Using a professional address separates your private residential address from any document accessible to the general public via the Companies Registry portal. This is especially relevant for directors who are individuals rather than institutions.
Guaranteed Availability
Companies Ordinance requires the registered office to be capable of receiving correspondence during business hours. A professional provider guarantees this — unlike a residential address, which may not be reliably attended.
Mail Handling and Notification
Reputable registered office providers do not simply receive your mail — they sort it, scan it, and notify you promptly. For time-sensitive documents such as IRD assessments or Companies Registry notices, a delay in receipt can mean a missed deadline. Digital scanning services ensure you see official correspondence the same day it arrives, regardless of where in the world you are based.
HEVEA HK includes mail handling and digital notifications as part of its registered office address service. You can view a scanned copy of any official document received at your registered office from anywhere.
Compliance With Company Secretary Requirements
Hong Kong companies are also required to appoint a company secretary who is either a natural person ordinarily resident in Hong Kong, or a body corporate registered in Hong Kong. Many companies bundle their registered office and company secretary services together for convenience and cost efficiency.
What Happens If You Use an Incorrect Address?
Using an invalid or incorrect registered office address is not a minor administrative oversight — it carries real legal consequences under Cap. 622.
Companies Registry Penalties
Failure to maintain a valid registered office, or failure to notify the Companies Registry of an address change within 14 days using Form NR1, constitutes an offence. Both the company and every responsible person (typically directors) can be liable for fines.
Missed Legal Notices
Legal documents served at your registered office are deemed validly served on your company, even if you never receive them. If your registered office address is incorrect or unmonitored, you may miss court summonses, statutory demands, or IRD assessments — with serious downstream consequences.
Non-Compliance Risk During Due Diligence
When your company undergoes due diligence — for a bank account application, a funding round, or a commercial contract — counterparties will check the Companies Registry. A discrepancy between your declared address and your registered office creates immediate red flags and can delay or derail commercial transactions.
Frequently Asked Questions
Can I use my home address as registered office in Hong Kong?
Technically yes — Cap. 622 does not prohibit using a residential address as your registered office. However, your home address would then appear on the publicly searchable Companies Registry. Most founders prefer to use a professional registered office service to keep their personal address off the public record.
Can I change my registered office address?
Yes. A company can change its registered office address at any time by filing Form NR1 with the Companies Registry within 14 days of the change taking effect. The new address must also be a physical address in Hong Kong — not a PO Box.
How long does it take to change a registered office address?
Once Form NR1 is filed and accepted by the Companies Registry, the change is typically reflected on the public register within a few business days. The filing itself takes approximately 15 minutes if your documents are in order.
Is a virtual office address accepted as registered office?
Yes, provided the address is a real physical address in Hong Kong and can receive correspondence during business hours. A professional business centre or registered office service provider qualifies. What is not accepted is a PO Box or a forwarding-only mail address with no physical premises behind it.
What is Form NR1?
Form NR1 is the statutory form used to notify the Companies Registry of a change of registered office address. It must be filed within 14 days of the change. It can be submitted electronically via the e-Registry portal or in paper form at the Companies Registry counter.
Does my registered office need to be open during business hours?
Yes. Under Cap. 622, the registered office must be a place capable of receiving correspondence and service of documents during normal business hours. A professional registered office service provider fulfils this requirement as part of its standard service.
Can a PO Box be a registered office in Hong Kong?
No. A PO Box cannot be used as a registered office address. The Companies Registry explicitly requires a physical address in Hong Kong. Using a PO Box would render the registered office address invalid and expose the company and its directors to penalties.
What documents go to my registered office?
Your registered office receives official government correspondence — primarily from the Companies Registry (annual return reminders, statutory notices) and the Inland Revenue Department (tax assessments, Business Registration Certificate renewals). It also receives any legal notices or court documents served on the company.
What is the difference between registered office and place of business?
The registered office is the formal legal address recorded with the Companies Registry for statutory correspondence. The place of business is where a company actually conducts its commercial operations. They can be the same address or different addresses. Only the registered office has a mandatory legal definition under Cap. 622.
Do I need a business address separate from my registered office?
Not necessarily. Many Hong Kong companies — particularly those operating remotely or internationally — have no separate business premises. Their registered office address serves all practical purposes. If you have staff, clients, or operations at a physical location in Hong Kong, that location will naturally function as your business address.
