Hong Kong Registered Office Address: Can You Use Your Home? Can You Use a PO Box? (2026)

At a glance

A registered office and “where your office is” are two different things. You can rent premises in Tsuen Wan and trade from there while using a service provider’s Central address as your registered office — entirely lawful.

Why is a registered office required?

Because the government and the courts need one place where they can definitely find you.

This is the address for legal service — notices from the Companies Registry, tax returns from the IRD, court summonses all go there. Once a document has been sent to the registered office, you are legally taken to have received it, whether or not you actually saw it.

That sentence is the whole point. Plenty of people assume “if I did not receive it, it is not my problem”, and that is not how it works. Companies have had a registered office nobody was looking after, tax returns arrived and were ignored, an estimated assessment and penalties accumulated, and the first they knew of it was a court document.

So the first test when choosing a registered office is not price. It is whether anyone will actually deal with the post.

Can you use your home address?

Legally, yes. But there are three things to think through.

1. Your home address becomes public. Companies Registry records are searchable by anyone, so knowing your company name is enough to find where you live. For anyone running an online business, exposed to customer disputes, or who simply does not want their personal details public, that is a real consideration.

2. Moving house means filing. Every move has to be filed with the Companies Registry within the deadline, and missing it carries a penalty. Renting and moving every few years means remembering it every few years.

3. Your landlord or lease may not allow it. Some residential leases prohibit use for business registration, and public housing has explicit restrictions. Check the lease before using it.

Why is a PO box not allowed?

Because what the law requires is an address at which documents can be served. A PO box is a mail slot — nobody is there, and legal documents requiring signature cannot be delivered.

By the same logic, a purely nominal virtual address service — where nobody actually handles the post and everything is simply forwarded — may be a physical address in form, but if nobody follows anything up the risk is much the same as a PO box: the document arrives and nobody reads it.

How does using a service provider’s address work?

This is the most common arrangement for SMEs, and it works roughly like this:

1. You use the provider’s Hong Kong office address as your registered office
2. All government and legal documents go there
3. The provider notifies you on receipt, scans it to you, or forwards it
4. Important statutory documents — tax returns, Companies Registry notices — are flagged to you directly for action

The benefits: your private address stays private, moving house requires no filing, and someone is watching the post so nothing is missed.

Questions worth asking before choosing:

• How quickly do they notify you after receiving something? (Some scan once a week, which will cost you on anything urgent)
• Are statutory documents actively flagged, or just forwarded?
• Is there a charge for forwarding?
• If you leave later, what is the process for moving the address?

We provide a registered address service, and it forms part of our company secretary service — documents are notified on receipt, with the statutory deadlines tracked alongside.

How do you file a change, and what if you are late?

It has to be filed, and there is a deadline. A change of registered office is filed with the Companies Registry on the prescribed form (NR1), generally within 15 days of the change.

The consequences of filing late or not at all are not trivial: a fixed penalty and a daily default fine, and leaving it unresolved long term can result in the company being struck off.

In practice the usual cause is not unwillingness — it is forgetting. You move house or move office, you are busy with everything else, and this one form gets missed. So if you handle this yourself, set a reminder before you move.

One more thing: changing the registered office and changing the business registration address are two separate filings — two departments, two forms. Doing one leaves the other out of date.

Are the registered office and the business registration address the same thing?

No, though many people assume so.

• Registered office: filed with the Companies Registry, used for service of legal documents
• Business registration address: filed with the IRD, the address at which you carry on business

The two can differ — a service provider’s address as the registered office, your actual shop or office as the business address. That arrangement is entirely normal.

But a change on either side has to be filed separately. This is the most commonly missed point. For the full set of statutory filings and deadlines, see what a company secretary does.

Do not find out nobody is reading the post when the court letter arrives

The registered office looks like the least important line on the incorporation form. It is in fact the one most likely to cause trouble — because it decides whether the government can find you.
