Hong Kong Business Registration Certificate (BR) Explained

A Hong Kong business registration certificate, often called the BR, is an official document issued by the Inland Revenue Department that shows a business is registered for tax purposes. Every business operating in Hong Kong needs one, it must be renewed regularly, and it carries the Business Registration Number that identifies your business in official dealings. It is not the same as your Certificate of Incorporation, and understanding the difference saves a lot of confusion.

This guide explains what the BR certificate is, how it differs from the certificate of incorporation, how to get one, what it costs, and the renewal and display rules you need to follow.

What the BR certificate is

The business registration certificate is proof that your business is registered with the Inland Revenue Department. It records your business name, address, the nature of business, and, importantly, your Business Registration Number.

Every business carrying on activity in Hong Kong is required to register, and that includes companies. So a Hong Kong limited company holds both an incorporation document and a business registration certificate. The BR is the tax-side registration; without a valid one, you are not properly registered to operate.

BR certificate vs certificate of incorporation

This is the distinction that trips people up, so it is worth being precise.

• Certificate of Incorporation (CI) is issued by the Companies Registry and proves your company legally exists as an entity. It carries the CR company number.
• Business Registration Certificate (BR) is issued by the Inland Revenue Department and proves your business is registered for tax. It carries the Business Registration Number.

In short, the CI creates the company; the BR registers it to do business and be taxed. A limited company needs both. When Hong Kong incorporates a company, the two are handled together under a one-stop process, so new companies receive both documents.

How to get a business registration certificate

How you obtain the BR depends on whether you are forming a company or running an unincorporated business.

If you are incorporating a limited company, business registration is handled together with incorporation through the one-stop process. You apply to incorporate, and the business registration certificate is issued alongside the Certificate of Incorporation. You do not file a separate standalone application first. The overall setup and its costs are covered in our Hong Kong company registration cost guide.

If you are running an unincorporated business, such as a sole proprietorship or partnership, you register the business directly with the Inland Revenue Department within the required time after starting to operate.

Either way, the result is the same document: a valid BR certificate carrying your Business Registration Number.

What it costs

The BR fee is set by the government and can change each year, and it sometimes includes a levy toward the Protection of Wages on Insolvency Fund.

You can choose a one-year or a three-year certificate. The three-year option costs more upfront but works out cheaper per year, which suits founders confident they will keep the company running. Because the fee is reviewed periodically and the levy can be added, waived, or restored, confirm the current amount before you pay rather than relying on an old figure.

Renewal, display, and keeping it valid

The BR is not a one-time document. It has to be kept current.

Renewal. The certificate is valid for its one-year or three-year term and must be renewed before it expires. The Inland Revenue Department normally issues a renewal demand ahead of time, and you pay to keep it valid. Letting it lapse means operating without a valid business registration, which carries penalties.

Display. You are generally required to display a valid business registration certificate at your place of business, so it should be kept accessible rather than filed away and forgotten.

Changes. If your business details change, such as the business name or address, you must notify the Inland Revenue Department so the certificate stays accurate.

Staying on top of BR renewal is part of the wider annual cycle every Hong Kong company runs, which we set out in our guide to Hong Kong company annual compliance. Official information on business registration is published by the Inland Revenue Department.
