Both a sole proprietorship and a partnership are unincorporated business structures in Hong Kong. Neither requires registration with the Companies Registry. Both require only a Business Registration Certificate from the IRD. But they have fundamental differences in ownership, liability, and decision-making that matter before you choose. This guide compares both structures across every relevant dimension so you can make an informed decision.
Highlights of this article
- A sole proprietorship is owned and operated by 1 person. A partnership requires 2 or more people (maximum 20 for a general partnership).
- Both structures have unlimited personal liability. There is no protection for personal assets from business debts.
- Both pay profits tax at the unincorporated business rate: 7.5% on the first HKD 2 million, 15% above that.
- Neither requires an annual audit, making compliance costs lower than a private limited company.
- For most founders planning to grow, hire employees, or raise investment, a private limited company is the better starting point. Both sole proprietorship and partnership are unsuitable for those goals.

Sole Proprietorship: What It Is
A sole proprietorship is a business owned by 1 individual. The owner and the business are the same legal person. There is no legal separation.
Liability: The owner is personally responsible for all debts, liabilities, and legal claims of the business. If the business cannot pay its debts, creditors can pursue the owner's personal assets: savings, property, and other personal belongings.
Registration: Apply for a Business Registration Certificate (BRC) from the IRD. No Companies Registry filing is needed. Cost: HKD 2,350 for a 1-year certificate from April 2026. Full registration details are on the IRD Business Registration page.
Tax: Profits tax at 7.5% on the first HKD 2 million of assessable profits and 15% above. The owner reports business profits in their individual tax return.
Best for: Solo freelancers, consultants, and independent professionals with low personal liability risk. For full details, see how to set up a sole proprietorship in Hong Kong. If you are considering incorporation instead, how to register a company in Hong Kong covers the full process.
General Partnership: What It Is
A general partnership is a business carried on by 2 or more persons with a view to profit. All partners are co-owners of the business. The maximum number of partners is 20 for most business types.
Liability: All general partners have unlimited joint liability. This means each partner is personally liable for all business debts, regardless of who incurred them. If one partner signs a contract that creates a debt, all partners are personally liable for that debt. This is the most significant risk of a general partnership.
Registration: Apply for a BRC from the IRD. No Companies Registry filing is required for a general partnership (unlike a limited partnership). Cost: HKD 2,350 for 1 year from April 2026.
Governance: The Partnership Ordinance (Cap. 38) governs general partnerships. A written partnership agreement is not legally required but is strongly recommended to define profit sharing, decision-making authority, and procedures for admitting or removing partners.
Tax: Each partner is taxed individually on their share of partnership profits at the unincorporated business rate (7.5%/15%). There is no entity-level tax on a partnership.
Limited Partnership: A Third Option
A limited partnership has 2 classes of partners:
- General partners (GP): Manage the business, have unlimited liability
- Limited partners (LP): Contribute capital only, cannot manage the business, have limited liability capped at their investment
A limited partnership must register with the Business Registration Office under the Limited Partnerships Ordinance (Cap. 37). Unlike a general partnership, registration with the Companies Registry is required.
If a limited partner participates in the management of the business, they lose their limited liability protection and become treated as a general partner for liability purposes.

Tax: Are They the Same?
Both sole proprietorships and general partnerships pay profits tax at the unincorporated business rate:
| Profits Level | Rate |
|---|---|
| First HKD 2,000,000 of assessable profits | 7.5% |
| Assessable profits above HKD 2,000,000 | 15% |
For a partnership, the profits are assessed at the partnership level and then allocated to each partner in their agreed ratio. Each partner pays tax on their share individually.
This rate is slightly lower than the corporate rate (8.25% on the first HKD 2M, 16.5% above) for private limited companies. However, for most founders, the difference in tax does not outweigh the value of limited liability and corporate credibility that a private limited company provides.
Banking and Credibility
Both sole proprietorships and partnerships face more friction when opening business bank accounts than private limited companies.
- Traditional Hong Kong banks (HSBC, Hang Seng, DBS) are more comfortable with incorporated entities for corporate account KYC
- Major commercial counterparties, lease agreements, and government contracts often require the other party to be an incorporated entity
- Digital payment platforms (Stripe, PayPal Business) typically require a company registration
- Investors cannot take an equity stake in an unincorporated business
For any business that anticipates significant banking relationships, commercial contracts, or growth, these practical limitations matter.
Which Should You Choose?
Choose a sole proprietorship if:
- You are the only owner with no co-founders
- You are a solo professional with low personal liability risk (e.g., freelance consultant, independent contractor)
- You want the simplest possible structure with minimal compliance cost
- You are testing a business idea before committing to incorporation
Choose a general partnership if:
- You have 2 or more founders who want to share ownership and profits
- You are in a profession that requires partnership structure (some legal, medical, and accounting practices)
- You understand and accept unlimited joint liability for all partners
Choose a private limited company if:
- You need limited liability protection
- You plan to hire employees, enter major commercial contracts, or raise investment
- You have foreign founders who want 100% ownership without restrictions
- You want credibility with banks, clients, and institutional counterparties

Converting to a Limited Company Later
Neither a sole proprietorship nor a partnership can be directly converted into a private limited company. You must:
- Incorporate a new private limited company with the Companies Registry
- Transfer all business assets, contracts, and licences from the old structure to the new entity
- Notify the IRD to cease the old business registration
- Update all bank accounts, vendor agreements, and client contracts to the new company name
This process is not automatic and can be time-consuming. Contracts require novation (agreement from both parties to transfer to the new entity). Some licences may require fresh applications. Bank accounts for the new company need to pass full KYC again.
The practical implication: if you expect to grow, hire staff, sign significant contracts, or raise investment within 2 to 3 years, incorporating from the start is cheaper than restructuring later. The cost difference between a sole proprietorship and a private limited company is approximately USD 1,000 to USD 2,000 per year in compliance costs. The cost and disruption of conversion often exceeds that difference.
