What Is a Business Registration Certificate?
A Business Registration Certificate (商業登記證, BR) is an official document issued by the Business Registration Office (BRO) of the Inland Revenue Department (IRD). It serves as the legal proof that a business is authorised to operate in Hong Kong. The certificate records:
- The registered business name
- The Business Registration Number (BRN)
- The registered business address
- The nature of business
- The certificate's validity period
The BR is the starting point for a business's formal existence in Hong Kong. Without it, the business cannot open a corporate bank account in the company's name, cannot file tax returns with the IRD, cannot apply for government grants or subsidies (such as the BUD Fund or the SFAA), and cannot enter into formal commercial arrangements with clients and suppliers who require proof of legal registration.
Business Registration Certificate vs Certificate of Incorporation: Key Difference
These two documents are frequently confused, particularly by founders setting up a limited company for the first time.
- Business Registration Certificate (BR): Issued by the IRD's Business Registration Office. Proves that a business is registered for tax and regulatory purposes. Required by all business types.
- Certificate of Incorporation (CI): Issued by the Companies Registry. Proves that a limited company has been legally incorporated as a separate legal entity. Only applicable to incorporated companies.
When establishing a limited company in Hong Kong, both documents are typically processed simultaneously — the Companies Registry and the Business Registration Office operate a one-stop registration service. For sole proprietorships and partnerships, only the BR is required; no CI is issued.
The BR and CI are complementary but distinct. The CI confirms the company's legal existence as a corporate entity; the BR confirms the business is registered for commercial operation and tax purposes.
Legal Consequences of Not Registering a BR
The penalties for failing to register — or for failing to maintain a valid registration — are significant and should not be underestimated.
Under the Business Registration Ordinance, a person who fails to apply for registration within the prescribed one-month period is liable on conviction to a fine of HK$5,000 and imprisonment for up to one year. Even where the matter does not proceed to court, an expired BR creates immediate practical problems: inability to open or maintain a corporate bank account, inability to file tax returns without complication, and disqualification from government grant applications.
If a business has been operating for more than 12 months without registering, all outstanding years of Business Registration fees and levies become payable upon eventual registration.
Who Must Apply for Business Registration in Hong Kong?
The Business Registration Ordinance applies broadly. The following categories of business are all required to hold a valid BR:
- Sole proprietorships and partnerships: Any individual or group operating a profit-making business under their own name or a business trading name must apply directly to the Business Registration Office.
- Local limited companies: When a limited company incorporation application is submitted to the Companies Registry, it is simultaneously treated as a Business Registration application. No separate BR application is needed — both documents are issued through the one-stop service.
- Non-Hong Kong companies: Overseas companies that establish a place of business in Hong Kong — even if their primary operations are conducted outside the territory — are required to register under the Business Registration Ordinance.
- Limited Partnership Funds: Funds registered in Hong Kong under the Limited Partnership Fund Ordinance must register regardless of whether they actively conduct business in Hong Kong.
Common Misconceptions: Who Also Needs a BR
Many business owners assume the BR only applies to physical retail operations. This is incorrect. The following are all required to hold a BR:
- Freelancers and self-employed professionals: Designers, translators, tutors, consultants, photographers, and any other self-employed individual providing services for profit are operating a sole proprietorship and must register.
- Online sellers: Individuals selling goods regularly for profit on Instagram, Facebook, Carousell, Xiaohongshu, or any other platform are conducting a commercial activity and must hold a BR.
- Cross-border e-commerce operators: Hong Kong-based sellers operating Shopify stores, Amazon accounts, or other cross-border platforms are also subject to the registration requirement.
- One important restriction: The IRD will not accept BR applications from businesses that have not yet commenced operations. Registration must be completed within one month of commencing business — not before. Early applications will be rejected.
Business Registration Fee Exemption: Who Qualifies?
Under Section 9 of the Business Registration Ordinance, certain small-scale businesses may apply for an exemption from paying the Business Registration fee and levy. An exemption means the fee is waived — but the business must still hold a valid Business Registration Certificate; the registration obligation itself is not waived.
Eligibility Criteria
[Table:1]
For existing businesses, the average monthly turnover is calculated over the six months immediately preceding the exemption application. For new businesses, it is based on the estimated average monthly turnover for the first six months of operation.
Additional Conditions
- Exemptions are only available to sole proprietorships and unlimited partnerships — limited companies are not eligible
- A sole proprietor who operates two or more businesses simultaneously is not eligible for an exemption on any of those businesses
- Exemptions are valid for one year and must be renewed annually
How to Apply
Submit Form 3 (IRBR61) in person or by post. For online renewals via GovHK, submit at least one week before the current BR expires; for in-person or postal submissions, allow at least one month.
Important: If a renewal fee notice arrives before the exemption is approved, pay the fee as instructed. The fee will be refunded once the exemption is confirmed.
Business Registration Number: What It Means
The Business Registration Number (BRN) is the unique identifier assigned by the IRD upon completion of registration. Understanding the structure of the BRN helps avoid confusion when using it across different official processes.
A standard BRN has the following structure:
- First 8 digits (e.g. 12345678): The core Business Registration Number — the company's tax identity. This is the number required for tax filings, opening corporate bank accounts, and official government communications
- Characters 9–11 (e.g. -000): The branch code. -000 denotes the main registered business address. If the business registers branches, they are assigned -001, -002, and so on
- Subsequent date and letter codes: Indicate the certificate's validity period and the annual assessment month
The BRN is not the same as the Company Registration Number (CR No.) issued by the Companies Registry for incorporated companies. For banking and tax filing purposes, the 8-digit BRN is the primary identifier.
How to Search Business Registration Records
Business registration information is a matter of public record under Section 19 of the Business Registration Ordinance. Anyone may search the register to verify the legitimacy of a business.
- Searching your own BR records: Log in to the eTax account on GovHK to view, download, and print your current Business Registration Certificate and any outstanding payment notices. You can also monitor recorded changes to your business address, partner additions or departures, and other registered details.
- Searching another company's BR records: Use the free search service on the GovHK platform, entering the business name and district. This returns the Business Registration Number and core details of any registered business — useful for verifying the legitimacy of a prospective partner or supplier before entering into commercial arrangements.
- Replacing a lost BR: If the original certificate is lost, damaged, or required for bank account opening, a duplicate can be obtained via eTax or GovHK at a cost of HK$20. A PDF copy is available for immediate download and is fully accepted by banks and government bodies.
Business Registration Certificate Fees: Full Fee Table
Business Registration fees consist of two components: the Registration Fee (paid to the government for administrative processing) and the Levy (which funds employee wage protection initiatives). Together, these constitute the total amount payable.
The following is the full fee table effective for the 2026/27 assessment year (1 April 2026 to 31 March 2027) under the IRD's latest published schedule:
[Table:2]
Note on fee calculation: Fees are assessed based on the commencement date of the registration period, not the date the application is submitted. For example, if a business commences on 1 March 2026 but the application is submitted on 2 April 2026, the commencement date of 1 March 2026 falls within the 2025/26 assessment year, and the 2025/26 rates apply (HK$2,200 total for a one-year certificate).
Branch Registration Certificates
If a business operates from multiple locations, each branch requires a separate Branch Registration Certificate. The legal requirement applies equally to every place of business — the BR for the main premises does not cover operations conducted at additional addresses. Branch registration fees are significantly lower than main business registration fees.
One-Year vs Three-Year Certificate: Which to Choose?
- One-year certificate (HK$2,350): Better suited to businesses in early exploratory stages, businesses that may change their registered address or business structure within the next few years, or businesses where cash flow makes a lower upfront outlay preferable.
- Three-year certificate (HK$6,170): The more economical choice for businesses with stable operations and a fixed address. Three consecutive one-year renewals cost a total of HK$7,050, making the three-year certificate approximately HK$880 cheaper over the same period. It also reduces the administrative burden of annual renewal.
How to Apply for a Business Registration Certificate: All Three Methods
Limited Companies
Limited companies do not apply for a BR separately. The Companies Registry and the Business Registration Office operate a one-stop registration service — when the incorporation application for a new limited company is submitted to the Companies Registry, the BR application is processed simultaneously. Both the Certificate of Incorporation and the Business Registration Certificate are issued together. For a comprehensive guide to the full company formation process, see our guide to setting up a private limited company in Hong Kong.
Sole Proprietorships and Partnerships
Three application methods are available for sole proprietorships and partnerships.
Method 1: Online Application via eTax (Recommended)
The online method is the most convenient and the fastest route to receiving an electronic Business Registration Certificate, typically within two working days of a completed application.
Prerequisite: A valid digital certificate or a registered iAM Smart+ account for identity verification. Without one of these, online submission cannot be completed.
Step-by-step process:
- Log in to the eTax portal on GovHK using your digital certificate or iAM Smart+ credentials
- Select the Business Registration application service
- Enter the business name, nature of business, commencement date, registered business address, and proprietor or partner details
- Upload required identity documents — HKID copy for the proprietor and all partners
- Complete identity verification electronically
- Pay the applicable Business Registration fee by credit card or online payment
- Receive confirmation; the electronic Business Registration Certificate is available for download within approximately two working days
The electronic BR has identical legal standing to a paper original. It may be printed on A4 paper and used for bank account opening, government applications, and all official purposes.
Method 2: In-Person Submission at the Kai Tak Tax Centre
In-person submission provides the fastest access to a physical Business Registration Certificate — typically within approximately 30 minutes of presenting completed documents, making it the preferred route when immediate physical documentation is required.
Location: Business Registration Office, Level 2, Kai Tak Tax Centre, 5 Concorde Road, Kowloon Bay, Kowloon, Hong Kong. Advance appointment booking through the online appointment system is strongly recommended to minimise waiting time.
Required documents:
- Completed Business Registration Application Form (Form IRBR194, obtainable from the IRD)
- HKID copy of the proprietor and all partners
- If neither the proprietor, any partner, nor any principal officer is a Hong Kong resident, a completed Form IRBR177 appointing a Hong Kong resident as local agent, together with the agent's identity document, is required
- Business Registration fee payment (cash or cheque accepted)
Step-by-step process:
- Arrive at the Kai Tak Tax Centre during business hours (Monday to Friday, 9:00am to 5:30pm; no lunch-hour closure for counter services)
- Collect a service queue number at the Business Registration counter
- Present completed Form IRBR194 and all required documents when called
- Pay the applicable Business Registration fee
- Collect the paper Business Registration Certificate — typically issued within the same appointment
If you are authorising someone else to submit on your behalf, the authorised representative must present the signed and completed application form, a copy of the proprietor's HKID, and their own identity document.
Method 3: Postal Application
The postal method is suitable for applicants who cannot attend in person and do not have access to digital identity verification tools. Processing time is approximately two working days after the letter is received by the Business Registration Office. The completed BR is returned by post to the registered business address.
Address for postal submission: PO Box 29015, Concorde Road Post Office, Kowloon
Required documents (same as in-person method):
- Completed Form IRBR194
- HKID copies for the proprietor and all partners
- A crossed cheque for the BR fee payable to "The Government of the Hong Kong Special Administrative Region" — do not send cash by post
- Sufficient postage on the return envelope
Important caution: Do not use postal application when the one-month registration deadline is approaching. The combination of postal transit time and processing time creates a meaningful risk of exceeding the statutory window. If the deadline is within two weeks, in-person submission is the safer choice.
Changing Your Business Registration Address: What to Do After a Move
Business relocation is a common event, and the address update obligation is one that many business owners overlook or delay. Under the Business Registration Ordinance, the Business Registration Office must be notified in writing within one month of any change to the registered business address. Late notification is a breach of the Ordinance and may attract penalties.
Two Methods for Address Updates
- Online via eTax: Log in to your eTax account and use the "Change of Business Particulars" function to update the business address. This is the fastest method and can be completed without visiting any government office. You will need to provide the old address, the new address, and the effective date of the change.
- Paper form submission: Complete Form IRC3111A (Notification of Change of Business Address), attach documentary proof of the new address, and submit in person or by post to the Business Registration Office at the Kai Tak Tax Centre.
Other Changes That Require Notification Within One Month
In addition to address changes, the following changes must also be notified to the Business Registration Office within one month:
- Change of business name (sole proprietorship or partnership): Form IRC3111A
- Change of business nature: Written notification or Form IRC3111A (sole proprietorship / partnership); Form IRBR191 (limited company)
- Addition or departure of a partner (partnership): Form IRBR64, signed by all incoming new partners, all departing partners, and all continuing partners
For limited companies, the Companies Registry's one-stop notification service means that certain changes registered with the Companies Registry are automatically transmitted to the Business Registration Office — but this does not cover all change categories, and business owners should confirm what requires separate notification.
Can I Use a Residential Address for Business Registration?
Private residential addresses may be used as a registered business address for sole proprietorships and some limited companies, subject to any deed of mutual covenant restrictions in the building. However, using a public housing flat (Housing Authority or Housing Society) as a business registration address is expressly prohibited and constitutes misuse of public housing, which may result in termination of the tenancy agreement.
For businesses that require a professional registered address without leasing commercial premises, virtual office and registered address services provide a compliant and cost-effective solution. For context on the options available, our guide to registered office addresses in Hong Kong covers the key considerations and practical costs.
How to Renew a Business Registration Certificate
As long as the business continues to operate, the BR must be renewed upon expiry. An expired BR means the business is no longer legally registered, creating both legal exposure and operational disruption.
The Renewal Notice
The Business Registration Office typically sends a renewal payment notice to the registered business address approximately one month before the certificate's expiry date. This notice serves a dual function: it is both a fee payment instruction and — once payment is made — the new Business Registration Certificate itself. The completed payment notice is the renewed BR. It does not need to be exchanged for a separate certificate. Keep it displayed at the business premises alongside any previously issued certificates.
Payment Methods for Renewal
[Table:3]
What to Do If the Renewal Notice Does Not Arrive
If you have not received the renewal notice within one month of the certificate's expiry date:
- Confirm that the registered business address on the BR is current and correct
- Contact the Business Registration Office by telephone (2594 3146) during office hours to request reissuance of the notice
- Alternatively, visit the Kai Tak Tax Centre in person and pay the renewal fee directly
Do not delay renewal because the notice has not arrived — the obligation to renew remains regardless of whether the notice is received. If the certificate lapses, penalties apply.
Note for three-year certificate holders: Because of the longer interval between renewal cycles, setting a personal calendar reminder twelve months before the expiry date is advisable to avoid inadvertently missing the renewal window.
Business Registration Certificate Expiry: Penalties and Remedies
Legal Penalties
Under the Business Registration Ordinance, failure to pay the Business Registration fee on time is a criminal offence. The maximum penalty is a fine of HK$5,000 and imprisonment for up to one year. In practice, the penalty for a first, minor late payment is typically around HK$300, but persistent non-payment or significant delays may result in a court summons and higher fines.
If the business has been operating without registration for more than 12 months, all outstanding years of registration fees and levies — from the commencement of business to the date of late registration — become payable in full.
Steps to Remedy an Expired BR
- Visit the Business Registration Office at the Kai Tak Tax Centre or use eTax immediately
- Pay all outstanding Business Registration fees and levies, including any penalty amounts specified in the overdue notice
- If a penalty notice has been issued, settle it in accordance with the instructions provided
- Retain all payment receipts as records
Prevention is significantly more effective than remedy. Paying promptly upon receipt of the renewal notice, and setting up the eTax electronic notification service to receive automated reminders, eliminates the risk of inadvertent non-renewal.
Understanding "CORP" and Business Nature on the BR
When a newly incorporated limited company receives its first Business Registration Certificate, the "Nature of Business" field typically displays "CORP" — short for Corporation — rather than a specific industry description. This default entry reflects the fact that the company has not yet notified the IRD of its specific business activities.
Why This Matters
Operating with "CORP" displayed as the business nature is a common situation for newly formed companies, but it should be updated as soon as the company commences its actual business activities. Under the Business Registration Ordinance, any change to the nature of business must be notified to the Business Registration Office within one month of the change taking effect. Starting a specific business activity without updating the BR accordingly is a technical breach.
How to Update From "CORP" to a Specific Business Nature
- Sole proprietorships and partnerships: Complete and submit Form IRC3111A.
- Limited companies: Complete and submit Form IRBR191 (Notification of Change of Business Nature), or submit a written notification clearly stating the company number, registered name, and updated business nature description. Once processed, the IRD will issue a new Business Registration Certificate reflecting the updated nature of business.
Business Nature Description Format
When completing the business nature field:
- Chinese description: maximum 30 Chinese characters (including punctuation)
- English description: maximum 60 alphabetical characters
The description should reflect the company's primary commercial activity accurately — for example: "Information Technology Consulting," "Retail Trading," "Restaurant and Food and Beverage Services," or "Import and Export of Electronic Products."
After Obtaining Your BR: Opening a Corporate Bank Account
Receiving the Business Registration Certificate completes the formal registration of your business. The most important next step is opening a dedicated corporate bank account in the business's name.
Commingling personal and business finances in a single bank account is one of the most common sources of accounting, tax, and compliance complications for small businesses. A dedicated business account provides a clear separation between personal and business cash flows, makes tax filing straightforward, allows clients and suppliers to make payments in the company's name, and significantly improves the professional credibility of the business.
Traditional banks in Hong Kong have historically presented challenges for newly registered SMEs: extensive documentation requirements, lengthy approval periods, minimum deposit thresholds, and in some cases outright refusal of accounts for small companies with limited operating history. For a comparison of the business banking options available, our guide to opening a company bank account in Hong Kong covers the full range of requirements across major banks.

Frequently Asked Questions
Does the Business Registration Certificate need to be displayed at the business premises?
Yes. Under the Business Registration Ordinance, the BR — or a printed copy of the electronic version — must be displayed in a prominent position at the registered place of business where it can be inspected by customers and regulatory officers. If the business operates from multiple locations, each premises must display the relevant BR or Branch Registration Certificate. Failure to display the BR may be treated as a breach of the Ordinance.
How do I cancel a Business Registration Certificate when closing the business?
When ceasing operations, the business must notify the Business Registration Office in writing within one month of the cessation date. For sole proprietorships and partnerships, complete Form IRC3113 or submit a written notice stating the business name, registration number, address, and date of cessation. For limited companies, complete Form IRBR191. Note that for limited companies, the IRD cessation process must be completed before the Companies Registry deregistration application can be submitted.
How do I obtain a certified copy or duplicate of my BR?
A duplicate copy for general use can be obtained via eTax or in person at the Business Registration Office at a cost of HK$20, with immediate PDF download available for online requests. If a bank or court requires a higher-specification legal document, apply for a Certified Extract of the Business Register entry — the current fee is HK$45 per extract, and same-day PDF download is available via GovHK.
How do I change the business name on the BR?
For sole proprietorships and partnerships: complete Form IRC3111A and submit to the Business Registration Office within one month of the name change. For limited companies: first submit a Notice of Change of Company Name to the Companies Registry. Once the Companies Registry issues the Certificate of Change of Name, the Business Registration Office will automatically update the BR (or process the update based on Form IRBR191) within a few days, issuing a new BR bearing the updated business name.
