What is the territorial source principle

What Is the Territorial Source Principle

Hong Kong taxes only profits that arise in or are derived from Hong Kong. This is the foundation of the city's profits tax system, setting it apart from jurisdictions that tax based on where a company is incorporated or resident. A Hong Kong company is not automatically taxed on its worldwide profits. The question is always where those profits were sourced.

Only profits with a Hong Kong source are chargeable. Profits that arise outside Hong Kong, commonly called offshore profits, are not assessable. The Inland Revenue Department applies this principle consistently. The taxpayer's place of incorporation, management, or control is not the deciding factor.

The key test is the locality of the profits. The IRD's primary guidance is Departmental Interpretation and Practice Note 21 (DIPN 21). That note explains how the IRD determines the source of profits from trading, manufacturing, services, and other business activities. This guidance follows case law, particularly the principle that the source is the operation that produced the profit, not the place where the profit was received.

Because of this principle, a Hong Kong company earning income from customers outside Hong Kong may treat that income as non-taxable. The exemption is not automatic. The company must demonstrate the profits arose outside Hong Kong, based on factors such as where contracts are concluded, goods are delivered, services are performed, and key business decisions are made.

Hong Kong Territorial Taxation Explained

The Inland Revenue Ordinance (Cap. 112) charges profits tax only on profits arising in or derived from Hong Kong. This is a source-based system, not one based on where a company is incorporated. The residence of the taxpayer is irrelevant. A company incorporated in the British Virgin Islands with a Hong Kong branch pays tax on its Hong Kong-sourced profits. A Hong Kong incorporated company with all operations in mainland China pays no Hong Kong tax on those profits.

Business owners must understand where their profits arise, not just where their company is registered. A Hong Kong company that carries on all its business outside Hong Kong may have no Hong Kong tax liability, provided it can prove the profits are sourced elsewhere.

Source of Profits in Hong Kong

The source of profits is determined by the operations that produced them, not by where the money is received or the customer is located. The leading case, cited in DIPN 21, establishes that the source of profits is the place where the profit-earning activity takes place.

For a trading business, the source is generally where contracts of purchase and sale are concluded. For a service business, it is where the services are performed. For a manufacturing business, it is where the goods are produced. A Hong Kong company that sources goods from China and sells them to European customers, with contracts concluded outside Hong Kong, may have offshore profits even if the company itself is registered in Hong Kong.

The burden of proof is on the taxpayer. The IRD will examine the facts. The company must maintain records to support its position.

DIPN 21 Hong Kong

DIPN 21 is the Inland Revenue Department's Departmental Interpretation and Practice Note on the locality of profits. It explains the IRD's approach to applying the territorial source principle. The note covers trading profits, manufacturing profits, profits from the provision of services, and profits from financial instruments and lending.

DIPN 21 is not law, but it sets out the IRD's interpretation of the law and the factors it considers when determining whether profits are chargeable. The note is updated periodically to reflect court decisions and changes in business practice. A company making an offshore claim should review DIPN 21 to understand what evidence the IRD expects.

The note is publicly available on the IRD website. It is the starting point for any analysis of whether a Hong Kong company's profits are sourced in Hong Kong or offshore.

Contrast with Residency-Based Taxation

Many jurisdictions, including the United Kingdom, the United States and Australia, tax their residents on worldwide income. A company incorporated in those places pays tax on all its profits, wherever they arise, subject to foreign tax credits or exemptions. Hong Kong does the opposite: it taxes only Hong Kong-sourced profits, regardless of ownership or control.

This difference makes Hong Kong attractive as a holding or trading company location. A Hong Kong company that earns foreign-sourced income and does not bring it into Hong Kong in a way that triggers an FSIE charge may pay no Hong Kong tax on that income. The company may still be taxable in the jurisdiction where the profits arise, and double tax treaties may provide relief.

The territorial source principle does not exempt a company from filing profits tax returns. Every Hong Kong incorporated company must file a return annually, even if it considers all its profits to be offshore and therefore not chargeable. The return must disclose the basis on which no tax is payable.
