In Hong Kong, business structures determine legal liability, contract authority, and mandatory filings. The three common types are sole proprietorship, partnership, and private company limited by shares. Most trading businesses choose a private company limited by shares or a limited liability company. This guide explains these options, their legal classifications, registration, costs, ongoing duties, and how to change structures later.
Key Takeaways
- The three most common types of business are sole proprietorships, partnerships, and private companies limited by shares.
- Five company types can be formed under the Companies Ordinance; most trading businesses use a private company limited by shares.
- Business registration is required across forms; company incorporation is a separate Companies Registry process.
What Are the Main Types of Business Structures in Hong Kong?
The main types of business structures for ordinary founders are a sole proprietorship, a partnership, and a private company limited by shares. That is the three-way choice among types of business entities when working out how to start a business in Hong Kong. The Companies Ordinance still allows five company types; those sit in a later section and matter mainly for listings, non-profits, or rare unlimited companies.
Structure | Best for | Liability | Separate legal entity |
|---|---|---|---|
| Sole proprietorship | One person, low-risk, simple start | Unlimited | No |
| Partnership | Two or more people sharing a trade | Unlimited for general partners | No |
| Private company limited by shares | Growth, a company bank account, or investment | Limited to unpaid shares | Yes |
Tax rates, government fees, and annual filings are covered after the three-way choice.
Choosing the legal form first prevents a second round of officer and address filings after the certificates are issued. Osome’s company registration service can incorporate a private company limited by shares, appoint a company secretary, and set the registered office so the filing matches how the business will trade.
Which Business Structure Fits Best?
There is no single best type of business to start. The right choice depends on the business model, funding needs, and relevant market trends. For most founders who want limited liability, a company bank account, or later investment, a private company limited by shares is the usual small business company structure. A sole proprietorship can still work when the work is low-risk, solo, and unlikely to need outside capital.
Use the following filters to pick the right business structure:
- Personal liability: whether private assets should sit outside business debts.
- Separate legal personality: whether contracts and property should sit in the business’s own name.
- Capital and credibility: whether banks, landlords, or investors expect a limited company.
- Admin load: business registration alone versus a company secretary, registered office, annual return, and audit.
- Purpose: trading for profit versus a non-profit that needs a guarantee company.
A startup company structure is usually a private limited company or limited liability company, because shares and limited liability support a scalable business. The next three sections unpack each common business type. Public, unlimited, and guarantee companies are other business structures; they appear in the Ordinance section after the three common forms.
Sole proprietors and general partners remain personally liable for business debts. Personal assets can be used to meet those debts if the business cannot pay. Limited liability applies only after a company is incorporated as a separate legal entity.
Sole Proprietorship
What it is
A sole proprietorship is a business one person owns. There is no separate legal entity, so business assets, contracts, licences, and debts sit with the owner. The business name must not suggest limited liability.
Best for
This is a frequent choice for freelancers and low-risk side trades. It is a poor fit for a startup once staff, premises, or outside capital appear.
Strengths and limitations
Strengths | Limitations |
|---|---|
| Simple start after business registration, with full control of decisions and profits. | Unlimited personal liability under pass through taxation, including personal tax return requirements. Many banks prefer a limited company before they will open a business bank account. |
| The business owner keeps all the profits, with no company secretary, annual return, or Companies Ordinance officer rules. | No shares to issue to investors; the name must not imply limited liability. |
Partnership
What it is
A business partnership is carried on by two or more partners under the Partnership Ordinance (Cap. 38). Business ownership is shared; partners are usually jointly liable, and any partner can bind the firm unless the agreement says otherwise. Profits and losses are assessed on the partners under pass through taxation, not on the firm as a separate taxpayer. A general partnership agreement is not a filing requirement, but it is the practical way to fix profit shares, signing authority, and what happens if a partner leaves.
Best for
A partnership fits two or more people who already trust each other and accept shared personal risk. It is less attractive than a private limited company once multiple owners want limited liability, a company bank account, or outside investors.
General and limited partnerships
General and limited partners sit under different rules:
- A general partnership is the default: every partner can bind the firm and remains personally liable for its debts.
- A limited partnership under the Limited Partnerships Ordinance (Cap. 37) must be registered with the Companies Registry. Limited partners are typically liable only up to their contribution if they stay out of management. General partners still have unlimited liability.
A limited liability partnership exists for Hong Kong law firms under the Legal Practitioners Ordinance. It is not a general trading option and should not be confused with a limited partnership registered under the Limited Partnerships Ordinance.
Private Company Limited by Shares
What it is
A private company limited by shares is a separate legal person. The company continues even if the shareholders change. Shareholders have personal liability protection, and are not liable for the company's debts beyond any amount unpaid on their shares. Hong Kong does not register a limited liability company (LLC); founders looking for that protection usually incorporate this limited liability company type. It is the default business structure for most commercial ventures. Its articles must restrict share transfers, cap members at 50 (excluding certain employee-members), and must not invite the public to subscribe for shares or debentures.
Best for
This is the usual pick for a startup company structure and for any founder who wants limited liability, a company bank account, or room to raise money through shares, including from venture capital. Most businesses that incorporate in Hong Kong use this form.
Requirements
Typical statutory minimums are:
- At least one natural-person director (any nationality; no Hong Kong residency requirement) and at least one shareholder, who may be the same person.
- A company secretary: an individual who ordinarily resides in Hong Kong, or a body corporate with a registered office or place of business in Hong Kong. The sole director of a private company cannot also act as its company secretary.
- A physical registered office in Hong Kong; a post office box alone is not accepted.
There is no statutory minimum share capital, but it cannot be zero. An English name must end with “Limited”, and a Chinese name with 有限公司. Form NNC1 is used on incorporation.

Strengths and limitations
Strengths | Limitations |
|---|---|
| Limited liability; the company can own assets, sign contracts, and raise money through shares. | Higher setup and ongoing cost: company secretary, registered office, annual return, and audit. |
| Stronger standing with banks, landlords, and investors than an unincorporated form. | More officers and filings from day one, including a significant controllers register. |
What Types of Companies Can Be Formed Under the Companies Ordinance?
The Companies Registry lists five different types of business structures that may be formed under the Companies Ordinance (Cap. 622). Companies are first classed as limited or unlimited. Limited companies may be limited by shares or by guarantee without a share capital; unlimited companies that can still be formed must have a share capital. Most businesses use a private company limited by shares. The other four types exist for public capital, non-profits, or rare unlimited-liability cases.
Unlimited companies without a share capital can no longer be formed.
Company type | Limited or unlimited | Share capital | Usual use |
|---|---|---|---|
| Private company limited by shares | Limited | Yes | Ordinary private trading and holding companies |
| Public company limited by shares | Limited | Yes | Larger businesses raising capital from the public |
| Company limited by guarantee without a share capital | Limited | No | Clubs, associations, and many non-profits |
| Private unlimited company with a share capital | Unlimited | Yes | Rare; members have unlimited liability |
| Public unlimited company with a share capital | Unlimited | Yes | Rare; members have unlimited liability |
In a company limited by shares, liability is limited to any amount unpaid on the shares. Private companies cannot offer shares to the public. Public companies face heavier disclosure and, like guarantee companies, must have at least two directors on the corporate board and cannot appoint a corporate director.
A company limited by guarantee has no share capital. Members undertake to contribute a stated amount if the company is wound up. Non-profit organisations operate for public or social benefit rather than financial gain, and must reinvest profits in the mission. Tax-exempt status under section 88 of the Inland Revenue Ordinance is a separate Inland Revenue Department recognition. Form NNC1G is used for a company not limited by shares.
Is a Branch One of the Company Types?
A branch is not one of the five types formed under the Companies Ordinance. The overseas parent registers as a non-Hong Kong company after it establishes a place of business here, using Form NN1 and a Notice to Business Registration Office (IRBR2), within one month. It must also appoint an authorised representative in Hong Kong. The parent remains liable for the branch’s debts. Founders who want a local business entity with limited liability incorporate a private company limited by shares instead.
Business Registration vs. Company Incorporation
Types of business registration and types of company registration are not the same filing. The Inland Revenue Department requires a person who conducts business in Hong Kong to apply for business registration. Incorporation of a local company is a Companies Registry process, and a Notice to Business Registration Office (IRBR1) is filed at the same time.
Form of business | Main filing | When |
|---|---|---|
| Sole proprietorship | Form 1(a) | Within one month after the business commences |
| Partnership | Form 1(c); a limited partnership also registers with the Companies Registry | Within one month after commencement |
| Local company | Form NNC1 or NNC1G, articles, and IRBR1 | Simultaneous with incorporation |
The Inland Revenue Department will not accept a sole proprietorship or partnership application for a business that has not commenced. Sole proprietorships and most partnerships can apply online via eTAX on GovHK. A valid Business Registration Certificate must be displayed at the place of business. Failure to apply is an offence liable to a fine of HK$ 5,000 and imprisonment for 1 year.
Keep the current levy table beside the application, because the total payable follows the certificate year rather than the day the form is printed. Specimen forms on the Inland Revenue Department website are for reference only and cannot be used to apply.
How Much Does Each Structure Cost?
Government fees are the official layer only. A limited company still needs a company secretary and a Hong Kong registered office, and it will incur accounting and audit costs that a sole proprietorship does not.
Form | Typical first-year government fees |
|---|---|
| Sole proprietorship or partnership | HK$ 2,350 |
| Private company limited by shares (electronic) | HK$ 1,545 for digital incorporation plus HK$ 2,350 for Business Registration fee and levy |
Hard-copy incorporation is HK$ 1,720. A 3-year business registration certificate costs HK$ 6,170 for certificates commencing from 1 April 2026 to 31 March 2027.
Those government fees start or renew registration; they are not income tax. The tax implications or possible tax exempt status come later: tax treatment depends on whether the business is unincorporated or a corporation. Profits tax is charged on assessable profits arising in or derived from Hong Kong. Unincorporated businesses are charged 7.5% on the first HK$ 2 million of assessable profits and 15% on the remainder.
For-profit corporations are charged 8.25% and 16.5% on the same bands; those are Hong Kong’s corporate tax rates, per the Inland Revenue Department’s profits tax rates. Remaining a sole proprietor or partnership keeps the lower unincorporated rates, which is the main tax advantage of those forms. In a group of connected entities, only one entity may use the two-tier rates in a year of assessment on the Hong Kong tax year and deadlines.
What Ongoing Duties Follow Each Structure?
Limited liability is not free. A private company buys asset protection with a business registration fee, a company secretary, a registered office, an annual return, a significant controllers register from day one, and audited accounts. A sole proprietorship or partnership avoids those Companies Ordinance filings and keeps only business registration and profits tax, at the price of unlimited personal liability.
Structure | Core ongoing duties |
|---|---|
| Sole proprietorship or partnership | Renew the Business Registration Certificate, keep accounts, and file a profits tax return as an unincorporated business. |
| Private company limited by shares | File the annual return, keep a significant controllers register, prepare audited accounts, and renew the Business Registration Certificate. Keeping accounts and filing a profits tax return are also required. |
| Company limited by guarantee | File annual accounts with financial statements, directors’ and auditor’s reports. Renew the Business Registration Certificate, keep accounts, and file a profits tax return as required. |
A private company’s annual return (NAR1) is due within 42 days after the anniversary of incorporation. The on-time fee is HK$ 105; late filing fees rise as high as HK$ 3,480.
Can a Business Structure Be Changed Later?
Changing business structure is possible, but Hong Kong does not convert a sole proprietorship into a limited company on the same file. As a business idea grows, the usual path is to incorporate a new company. Business assets and day-to-day business operations then move across, after which the old business registration is cancelled or left idle. The old certificate does not become the company’s registration; the company is a different legal person.
Typical steps are:
- Incorporate the new company and obtain its Certificate of Incorporation and Business Registration Certificate.
- Novate or re-sign contracts, leases, licences, and supplier accounts into the company’s name.
- Open a company bank account and stop mixing personal and business funds.
- Transfer assets, keep invoices in the correct name from the switch date, then cancel or let lapse the old registration when that business has stopped.
Example
A designer registered as a sole proprietor who later hires staff would incorporate a private company, move the employment contracts into the company’s name, then cancel the sole-proprietorship business registration. Invoices issued in the old personal name do not automatically belong to the new company.
How Osome Can Help
Choosing among types of business structures only helps if the chosen form is filed correctly and then kept in good standing. Osome supports incorporation of a private company limited by shares and the first officer appointments that a limited company must have from day one.
Startups, small businesses, medium-sized businesses, and international founders can keep statutory records, annual returns, and officer changes in one place rather than assembling those roles in-house. That keeps the legal structure aligned with how the business actually trades, including through company secretary support.
Check out the incorporation packages available to find the best fit for your business needs.
Summary
A sole proprietorship is the lightest start but leaves personal assets exposed. A partnership suits two or more business owners who accept shared liability. A private company limited by shares is the usual choice when limited liability, a company bank account, or later investment matter. Switching later means incorporating a new company and moving contracts across, so officers and the Companies Registry application are cheaper to line up before the first invoice.
