Key takeaways
- A sole proprietorship is an unincorporated business owned by one individual, with no legal separation between owner and business. You must apply for a Business Registration Certificate within one month of starting to trade.
- As a sole proprietor, you have unlimited personal liability, meaning your personal assets are at risk if the business cannot pay its debts.
- Profits Tax for unincorporated businesses is charged at 7.5% on the first HK$2 million of assessable profits and 15% on the remainder. You report business income through Part 5 of your Tax Return - Individuals (BIR60).
- Self-employed persons contribute 5% of relevant income to MPF (capped at HK$1,500 per month). As your business grows, you may consider incorporating as a limited company for liability protection and credibility.
What is a sole proprietorship?
A sole proprietorship is an unincorporated business owned and run by one individual. There is no legal separation between you and your business, which means you operate as a self-employed person.
This structure suits freelancers, independent contractors, tutors, consultants and anyone running a side business. It offers a straightforward way to start trading without forming a separate legal entity. If you want to learn the basics, see this guide to small business accounting.
Advantages of a sole proprietorship
Running a sole proprietorship in Hong Kong comes with several benefits, especially when you are starting out.
Easy and low-cost to set up
You do not need to incorporate a company or file formation documents with the Companies Registry. The main requirement is obtaining a Business Registration Certificate, which costs a fraction of what company incorporation involves.
Full control over your business
You make all decisions without needing approval from directors, shareholders or partners. This allows you to respond quickly to opportunities and run the business your way.
Simple tax reporting and compliance
Your business income is reported on your personal tax return rather than through a separate corporate filing. There are no requirements for audited accounts or a company secretary.
Keep all the profits
After paying Profits Tax, everything the business earns belongs to you. There is no need to distribute dividends or share profits with co-owners.
Disadvantages of a sole proprietorship
A sole proprietorship also carries risks you should weigh before deciding on this structure.
Unlimited personal liability
Because there is no legal separation between you and the business, you are personally responsible for all debts and legal claims. Creditors can pursue your personal savings, property and other assets.
Harder to raise capital and grow
Banks and investors often prefer lending to or investing in limited companies. Without shares to offer, attracting outside funding can be difficult. Monitoring your finances closely and learning to forecast your cash flow becomes even more important.
No business continuity
The business cannot exist independently of you. If you become ill, retire or pass away, the sole proprietorship ends unless you transfer it or convert it to another structure.
Work-life balance pressure
You carry full responsibility for every aspect of the business, from operations to administration. Without employees or partners to share the load, long hours are common.
How to set up a sole proprietorship in Hong Kong
Setting up is straightforward. Follow these five steps to get started.
- Choose a business name. You can use a Chinese name, an English name, or both. There is no separate name reservation process for sole proprietorships.
- Apply for a Business Registration Certificate from the Inland Revenue Department's Business Registration Office within one month of commencing business, as required under the Business Registration Ordinance (Cap. 310).
- Arrange any industry-specific licences or permits your trade requires, such as a food licence for catering or a travel agent licence.
- Enrol in a Mandatory Provident Fund (MPF) scheme as a self-employed person within 60 days of becoming self-employed.
- Set up your record keeping and open a business bank account to keep personal and business finances separate. Using software to keep clear business records from day one saves time later.
Sole proprietorship tax obligations in Hong Kong
Understanding your tax responsibilities helps you stay compliant and avoid penalties.
Profits Tax for unincorporated businesses uses a two-tiered rate system: 7.5% on the first HK$2 million of assessable profits and 15% on the remainder. Hong Kong also does not impose GST, VAT or sales tax, which simplifies your obligations.
You report your business income through Part 5 of the Tax Return - Individuals (BIR60). The year of assessment runs from 1 April to 31 March. If your gross income does not exceed HK$2 million, you do not need to attach financial statements to your return, though you should still be able to prepare financial statements if requested.
You must keep business records for at least seven years. This includes invoices, receipts, bank statements and any documents supporting your income and expenses.
For MPF, self-employed persons contribute 5% of relevant income. No contribution is required if your monthly income is below HK$7,100. The contribution is capped at HK$1,500 per month (based on a maximum relevant income of HK$30,000 per month).
Sole proprietorship vs limited company
The main alternative to a sole proprietorship in Hong Kong is a private company limited by shares (Ltd), incorporated with the Companies Registry under the Companies Ordinance (Cap. 622). Here is how they compare:
- Legal identity: A sole proprietorship has no separate legal identity. A limited company is a distinct legal entity from its shareholders and directors.
- Liability: Sole proprietors face unlimited personal liability. Shareholders in a limited company are liable only up to their unpaid share capital.
- Setup cost and effort: Registering a sole proprietorship is cheaper and faster. Incorporating a limited company involves higher fees, more paperwork and ongoing filing requirements.
- Tax: Sole proprietors pay Profits Tax at 7.5% then 15%. Limited companies pay 8.25% on the first HK$2 million of assessable profits and 16.5% on the rest.
- Compliance: A limited company must file an annual return, produce audited accounts, appoint a company secretary and maintain its own business registration. A sole proprietorship has lighter obligations.
- Continuity: A limited company continues to exist even if shareholders or directors change. A sole proprietorship ends with its owner.
A sole proprietorship works well when you are testing an idea, working as a freelancer or running a small operation with limited risk. As turnover grows, or if you want to bring in investors, limit your liability or build a business that continues beyond your involvement, incorporating as a limited company may be the better path. Either way, generating financial reports regularly helps you make informed decisions.
Legal considerations and insurance
Beyond business registration, check whether your trade requires additional licences or permits. Examples include a hawker licence for street vending, a money lender licence, or approval from the Estate Agents Authority for property work.
Because you carry unlimited liability, insurance can help protect your personal assets:
- Public liability insurance covers claims if a third party is injured or their property is damaged because of your business activities.
- Professional indemnity insurance protects you against claims of negligence, errors or omissions in the professional services you provide.
- Business or property insurance covers loss or damage to equipment, stock and premises.
