Sole Proprietorship in Hong Kong: How to Register, Tax Rates, and When a Limited Company Is Better

If you’re starting a small business in Hong Kong and want the simplest legal structure available, a sole proprietorship is where most people begin looking. It’s cheap to set up, quick to register, and doesn’t require the annual audit or company secretary that a limited company demands.

But “simple” comes with trade-offs. Your personal assets are on the line for every business debt. Raising investment is difficult. And if you’re a foreign founder, the registration requirements are harder to meet than they first appear.

This guide covers everything you need to decide whether a sole proprietorship is right for your situation: what it is, who qualifies, how to register step by step (with 2026-current fees), the tax obligations, and a direct comparison to a Hong Kong limited company so you can choose the right structure before committing.

What Is a Sole Proprietorship in Hong Kong?

A sole proprietorship is a type of business entities owned and operated by one person. It is not a separate legal entity — the owner and the business are the same thing in the eyes of the law. That means the owner receives all profits directly, but is also personally liable for every debt, obligation, and legal claim the business incurs. 

The owner also has compliance responsibilities, and it will be the owner who can be fined or penalised by the authorities for failure to comply with tax and commercial obligations.

In Hong Kong, a sole proprietorship is sometimes called a “sole trader” business. A person running a sole proprietorship business may be called a sole proprietor.

Advantages and Disadvantages

Who Can Register a Sole Proprietorship in Hong Kong?

Anyone who is operating a business in Hong Kong can register a sole proprietorship. You must hold a valid form of identification, and your business must already be in operation, as the IRD does not accept applications for businesses that have not yet started.

Can Foreigners Register as a Sole Proprietor?

Yes, foreigners can register as a sole proprietor in Hong Kong, but it is significantly more challenging than it sounds. You will need to meet specific conditions:

• You need to prove that your business genuinely operates in Hong Kong — not just uses Hong Kong as a registered address. The IRD may specifically requires detailed information from non-residents to determine whether a business qualifies as ‘operating in’ Hong Kong.
• Online registration requires a digital certificate (iAM Smart+ or ITP account), which is available only to residents. 
• According to the IRD, if the owner is not residing in Hong Kong, they are required to appoint a Hong Kong resident as their local agent for business registration.

How to Register a Sole Proprietorship in Hong Kong (Step by Step)

To register a sole proprietorship in Hong Kong, you need to register your business with the Business Registration Office under the Inland Revenue Department (IRD) and obtain a Business Registration Certificate (BRC), along with a Business Registration Number— which serves as your business’s unique identifier for tax and official purposes.

This registration must be done within one month of starting your business. Failure to register on time may result in a fine of up to HKD 5,000 and/or imprisonment for up to one year.

The application process involves the following steps:

Step 1: Choose a Business Name

When you register your sole proprietorship business, you have the option to use your legal name or select a trade name, sometimes called “doing business as” (DBA) name. 

You can choose to register a Chinese name only, an English name only, or both a Chinese and an English name. If you choose a Chinese name, it may include English letters, but not English words.

Because a sole proprietorship is not a separate legal entity, your business name must not imply incorporation. Avoid endings like “Limited,” “Ltd.,” or “Corp.” — these are reserved for incorporated companies.

Step 2: Prepare Your Documents

Before applying, have these ready:

Step 3: Submit Your Application

You can register through two channels:

Online (via eTAX on GovHK)

• Go to the Application for Business Registration page and click “Apply Now.”  
• Accept the Personal Information Collection Statement.
• Select “Individual Tax Portal” as the application type (sole proprietors pay individual tax, not corporate tax).

• Log in with your iAM Smart+ or ITP account.
• Select “Sole Proprietorship” as the business type.
• Fill in your personal details and business particulars.
• Choose a 1-year or 3-year certificate.
• Sign digitally and submit.

The whole process takes about 10–20 minutes if you have all the documents ready.

In case you are not residing in Hong Kong and must appoint a local representative, you will then need to complete and submit Form IRBR177, or provide an appointment letter that includes the agent’s name, Hong Kong Identity Card (HKID) number (with a copy), and residential address.

Offline (in person or by post)

• You must first obtain “Application Form 1A” from the Inland Revenue Department (IRD). You can do this by downloading the request form and submitting the request by email to taxbro@ird.gov.hk, by fax to +852 2824 1482, or by collecting the form in person at the Business Registration Office located on the 2nd floor of the Inland Revenue Centre in Kai Tak, Kowloon, Hong Kong. This is what Form 1A looks like.

• Complete Form 1A with your personal and business details.
• Submit the form in person at the Business Registration Office or by post to P.O. Box 29015, Concorde Road Post Office, Kowloon, Hong Kong. Ensure sufficient postage is paid, as underpaid mail will be rejected

Step 4: Pay the Registration Fee

The fee depends on whether you choose a 1-year or 3-year certificate:

How to pay for the registration fees  

• Online payment: JCB, Visa, Mastercard®, UnionPay, FPS, or PPS. Note that FPS and PPS may not work on all mobile devices. After payment, you’ll receive a Transaction Reference Number. Save this — you’ll need it to check your application status and collect your certificate.
• Offline payment: Pay at the counter when submitting in person, or include payment with your postal application.

Step 5: Collect Your Business Registration Certificate

Tax Obligations for Sole Proprietors in Hong Kong

A sole proprietorship business profit is taxed under the “Unincorporated Business Tax” rates, which are as follows:

A sole proprietorship is not a separate corporate entity, so its business income is not taxed as corporate income. For comparison, incorporated companies (limited companies) pay 8.25% on the first HKD 2 million and 16.5% above that. So the sole proprietorship rate is slightly lower at both tiers.

Tax Report

Sole proprietorship income is reported on the owner’s individual tax return, specifically in Part 5 of the Tax Return – Individuals (BIR60).

Below is the requirement

Filing deadline: The IRD issues tax returns annually, usually in May. You must submit your return within 3 months from the date of issue, or within 4 months if filing electronically.

Sole Proprietorship vs. Limited Company in Hong Kong

The main difference between a sole proprietorship and a limited company in Hong Kong is liability and legal status: a sole proprietor has no legal separation from their business and bears unlimited personal risk, while a limited company is a separate entity that shields shareholders’ personal assets. Here’s how they compare across the factors that matter most.

Which Structure Is Right for You?

A sole proprietorship makes sense if all of the following are true:

• You are a Hong Kong resident (or hold a valid work visa)
• Your business is small-scale, local, and low-risk
• You don’t need to raise external capital or issue shares
•  You’re comfortable with unlimited personal liability
•  You want the lowest possible compliance burden

A limited company is the better choice if any of these apply:

• You are a foreign founder or not based in Hong Kong
• Your business involves cross-border transactions
• You need liability protection — your personal assets should not be at risk
•  You need credibility with international clients, suppliers, or banks

A sole proprietorship is well-suited for local freelancers, small retailers, and individuals testing a business idea with minimal financial risk. However, for cross-border businesses, foreign entrepreneurs establishing a presence in Hong Kong, or companies planning to scale and requiring a more robust structure, forming a limited company is generally the more appropriate choice.
