A trader headquartered in Hong Kong with operations across Southeast Asia receives an assessment and discovers that supposedly overseas profits are taxable in Hong Kong because the key contracts were concluded by email from the Hong Kong office.
Hong Kong is known for a simple, transparent, low-tax system whose foundation is the territorial source principle.
The principle appears straightforward but involves considerable detail in practice. It determines whether your company pays Hong Kong profits tax on overseas income and is essential knowledge for anyone doing business in Hong Kong or planning to enter the market.
At a Glance: Which Income Is Taxable?
The table below summarises the treatment of common income types before examining the details:
| Income Type | Key Determining Factor | Subject to Hong Kong Profits Tax? |
|---|---|---|
| Ordinary trading profits | Where purchase and sale contracts are effected, including negotiation and conclusion. | Taxable if contracts are effected in Hong Kong; not taxable if effected outside Hong Kong. |
| Manufacturing profits | Where manufacturing takes place. | Taxable if manufactured in Hong Kong; profits attributable to overseas manufacturing processes are not taxable. |
| Service fees and commissions | Where services or relevant activities are performed. | Taxable if services are provided in Hong Kong; not taxable if activities take place entirely overseas. |
| Property rental income | The property’s location. | Taxable if the property is in Hong Kong. |
| Passive income, such as dividends and interest | Consider the location of income-generating operations and the new requirements of the Foreign-Sourced Income Exemption (FSIE) regime. | Complex and usually requires professional assessment. |
The Core Principle: What Is Territorial Taxation?
Hong Kong uses the territorial source principle of taxation. Only Hong Kong-sourced profits are taxable locally; profits sourced elsewhere are not subject to Hong Kong profits tax.
This differs fundamentally from worldwide taxation in countries such as the United States and mainland China, which tax residents’ worldwide income. Hong Kong taxes only profits arising in Hong Kong.
All three conditions must be satisfied for Hong Kong profits tax to apply:
- A trade, profession or business is carried on in Hong Kong.
- Profits arise from that trade, profession or business.
- Those profits arise in or are derived from Hong Kong.
The first two conditions are relatively straightforward. The difficult question is the third: how to determine the source of profits.
How the Source of Profits Is Determined
There is no universal formula. The source depends on the specific facts of each case. The department and courts follow established principles, most importantly the operations test.
The operations test examines what the taxpayer did to earn the profits and where those activities took place. In other words, the location of substantive profit-generating operations determines the source.
Important principles when applying the test include:
- Distinguish primary from incidental activities: focus on the location of the core profit-generating transactions. Preparatory or ancillary activities, such as renting an office or recruiting general staff, are not normally decisive.
- Decision-making location is not conclusive: the place of day-to-day decisions is one factor and is usually not decisive.
- Overseas offices: having no overseas office does not mean every profit is Hong Kong-sourced. However, if the main business location is Hong Kong and no overseas office exists, profits are likely to be taxable in Hong Kong.
Applying the Source Test in Different Industries
Trading companies: the key is where purchase and sale contracts are effected. This covers the whole process of negotiating, concluding and carrying out contractual terms, not merely legal signing.
Where sales are to Hong Kong customers, including overseas buyers’ Hong Kong purchasing offices, the sales contracts are generally regarded as effected in Hong Kong. Contracts concluded from Hong Kong by telephone or email are also regarded as effected there.
Manufacturers: profits are sourced where the goods are manufactured. Profits from goods made in Hong Kong are wholly taxable locally. If part of the manufacturing takes place overseas, the profits attributable to it are not regarded as Hong Kong-sourced.
Services and commissions: the source depends on where the services or relevant activities are performed. Commission income, for example, arises where the activity of arranging a transaction takes place.
Recent Changes: The Foreign-Sourced Income Exemption Regime
To meet international tax standards, Hong Kong introduced the revised Foreign-Sourced Income Exemption regime on 1 January 2023, significantly affecting member entities of multinational enterprise groups.
The regime mainly covers four categories of foreign-sourced passive income: dividends, interest, intellectual property income and disposal gains, such as gains on shares or assets. When specified foreign-sourced income is received in Hong Kong, it is treated as Hong Kong-sourced taxable income unless specified exemption conditions are met.
The main exemption conditions include:
- Economic substance: for non-IP income, such as dividends and interest, the entity must conduct sufficient substantive economic activities in Hong Kong, including strategic decisions and managing and assuming principal risks, with adequate employees and operating expenditure.
- Participation: dividends and disposal gains may qualify for a participation exemption where conditions such as holding at least 5% of the investee’s equity are met.
- Nexus: exemption for IP income depends on the proportionate connection between the taxpayer’s R&D expenditure and that income.
The reform means that the traditional assumption that all overseas passive income is tax-free needs updating. Businesses must review their structures and operations for compliance.

Frequently Asked Questions
No. Hong Kong taxation is based on where profits arise, rather than where funds are remitted. If profits are confirmed as overseas-sourced, remitting them to Hong Kong does not make them taxable.
Not necessarily. The key is not where customers are but where the core profit-generating operations occur. If procurement, negotiation and conclusion of sales contracts and supply-chain management take place in Hong Kong, the profits may still be Hong Kong-sourced even where goods and customers are overseas.
If you are a member of a multinational enterprise group and receive foreign-sourced dividends, interest, IP income or asset disposal gains in Hong Kong, you are likely to be affected and should assess economic substance and other exemption conditions. For traders conducting purely active trading businesses, ordinary profits from buying and selling goods are generally outside the regime.
Prepare and retain complete business records showing how profits arose. These may include contracts, negotiation correspondence and meeting minutes, logistics documents, evidence of marketing locations and order-processing records. Together they should show that substantive profit-generating operations took place outside Hong Kong.
