To change a Hong Kong company’s registered office address, deliver Form NR1 to the Companies Registry within 15 days after the change takes effect. If the company’s business address is also changing, check whether the Inland Revenue Department (IRD) needs a separate notification: a registered office and a business address are not necessarily the same.
Registered office or business address: which one is changing?
A registered office is the Hong Kong address where official communications and notices can be sent. A business address is the address recorded for the company’s business registration. One address may serve both purposes, but changing one does not always mean the other has changed.
If you need a Hong Kong address with mail receipt and government correspondence handling, see the virtual office service. Confirm the effective date of the address change and how incoming official mail will be handled before the change takes effect.
How to change your company’s registered office address
- Confirm the new address and effective date.
Make sure the company can receive official correspondence there. If you are moving to a service provider’s address, confirm that the address can be used as your registered office and agree on arrangements for forwarding or scanning mail. - Complete Form NR1.
Form NR1 is the Companies Registry’s “Notice of Change of Address of Registered Office.” Use the current form and follow its completion instructions. The Registry lists the official NR1 form and download options. - Deliver Form NR1 within 15 days.
The notice must be delivered to the Companies Registry for registration within 15 days after the change. The Registry’s filing requirements guide states the deadline and explains that late delivery may lead to penalties. - Check whether you also need to notify the IRD.
If only the registered office changes and the business address stays the same, the Companies Registry transmits the registered-office change to the IRD; you do not need to make a separate IRD notification for that change. If the business address also changes to a different address, notify the IRD within one month. The IRD accepts written notification or Form IRC3111A, and also provides an online service. See the Companies Registry’s one-stop notification FAQ and the IRD’s business-address guidance.
If the new business address is the same as the new registered office, the Companies Registry and IRD offer an optional electronic one-stop notification that can report both changes together. If the two addresses differ, do not assume that filing NR1 updates the business address as well.
After filing: check records and mail arrangements
Keep a copy of the submitted notice and check the company’s public record after registration. Update banks, customers, suppliers, insurers, and any licensing bodies or counterparties that need the company’s current contact details. These updates are separate from the NR1 filing.
If you would like help coordinating an address change alongside company records and ongoing statutory matters, review the Hong Kong company secretary service. Its listed support includes statutory records, compliance filings, and assistance with ad hoc corporate changes.
Frequently asked questions
How long do I have to file Form NR1?
Deliver Form NR1 to the Companies Registry within 15 days after the registered office address changes.
Do I need to notify the IRD after filing NR1?
Not separately when only the registered office changes and the business address remains the same. If the business address also changes to a different address, notify the IRD within one month. An optional electronic one-stop service is available when reporting the new registered office and business address together at the same address.
Does changing the registered office automatically change the business address?
No. The two addresses serve different purposes. Check the address shown on the Business Registration Certificate and notify the IRD if the company’s business address has changed.
