Territorial Source Principle: How Hong Kong Taxes Only Locally Sourced Profits

What Is the Territorial Source Principle in Hong Kong Profits Tax?

Hong Kong imposes profits tax on a territorial source basis. Only profits arising in or derived from Hong Kong are chargeable. Profits sourced outside Hong Kong are not subject to tax, regardless of the taxpayer’s residence or domicile. This distinguishes Hong Kong from jurisdictions that tax worldwide income.

The Inland Revenue Department (IRD) applies this principle through Departmental Interpretation and Practice Note 21 (DIPN 21). That guidance explains how the locality of profits is determined.

Hong Kong Territorial Source of Profits

The territorial source concept is the foundation of the profits tax system. Section 14 of the Inland Revenue Ordinance (Cap. 112) charges profits tax on “profits arising in or derived from Hong Kong” from a trade, profession or business carried on in Hong Kong. The IRD does not tax profits that arise outside Hong Kong, even if the taxpayer is a Hong Kong resident company. A non-resident who carries on business in Hong Kong and derives profits here is chargeable.

Where did the profits arise? The answer depends on the operations that generated them, not on where the taxpayer is incorporated or resident. This is the “operation test”, the central method the IRD uses to determine locality.

DIPN 21 Locality of Profits

DIPN 21 is the IRD’s authoritative interpretation of the territorial source principle. It sets out the Department’s approach to determining the source of profits for trading profits, manufacturing profits, service fees, and interest income. The guidance emphasises a single point: the locality of profits is a question of fact. Answer it by examining the operations that produced the profits.

For trading profits, the IRD looks at where the contracts of purchase and sale are effected. For manufacturing profits, the source is where the manufacturing operations take place. For service income, the source is where the services are performed. DIPN 21 also addresses more complex scenarios. Profits from intellectual property may turn on where the activities that created the intellectual property occurred.

Hong Kong Offshore Profits Exemption

The offshore profits exemption is the practical application of the territorial source principle. A taxpayer who demonstrates that its profits are sourced outside Hong Kong obtains an exemption from profits tax on those profits. This is not a statutory exemption in the usual sense. It is a consequence of the territorial basis: the IRD has no power to tax offshore profits.

Taxpayers claiming offshore treatment must file a profits tax return (Form BIR51 for corporations) and provide supporting evidence. The IRD examines the facts. If the evidence is insufficient, it may issue an assessment treating the profits as onshore. The burden of proof lies with the taxpayer. A successful offshore claim requires clear documentation showing that the key operations giving rise to the profits occurred outside Hong Kong.

Territorial Basis Hong Kong Tax

The territorial basis tax system means the IRD does not tax worldwide income. For a Hong Kong company, only profits that arise in or are derived from Hong Kong enter assessable profits. Profits from overseas operations, even if remitted to Hong Kong, are not chargeable unless the operations themselves were carried on in Hong Kong.

The territorial basis applies to all categories of profits tax payers: corporations, unincorporated businesses, and non-resident persons. The year of assessment and basis period are the same for all taxpayers. What changes is the source of profits, which determines what enters the chargeable profits.

Factors the IRD Considers in Determining Locality

The IRD applies the operation test by examining the facts of each case. Relevant factors include where the contracts for the purchase and sale of goods are made and executed, where the goods are manufactured or produced, and where the services are performed. The IRD also considers where the customer is located and where payment is received, where the business decisions are made and where the management is located, where the employees who generate the profits are based, and where the assets used to generate the profits are situated.

No single factor is decisive. The IRD considers the totality of the operations and identifies those essential to the earning of the profits. DIPN 21 provides detailed guidance on how these factors apply to different business activities.

Relationship with the FSIE Regime

The Foreign-Sourced Income Exemption (FSIE) regime, effective from 1 January 2023 and expanded from 1 January 2024 to cover disposal gains, operates alongside the territorial source principle. The FSIE regime applies to members of multinational enterprise (MNE) groups that receive certain types of foreign-sourced income in Hong Kong. Under the FSIE, such income is deemed to be derived from Hong Kong and is chargeable to profits tax unless an exception applies.

The exceptions are the economic substance requirement (for passive income such as interest, dividends, and disposal gains), the nexus requirement (for intellectual property income), and the participation exemption (for disposal gains from shares). The FSIE regime does not replace the territorial source principle. It adds an additional layer of rules for MNE groups. For non-MNE groups, the territorial source principle continues to apply without modification.

Practical Implications for Business Owners

The territorial source principle affects every aspect of tax compliance. When filing a profits tax return, determine the source of each income stream. If any profits are claimed as offshore, be prepared to provide evidence to the IRD.

The IRD challenges an offshore claim where the taxpayer cannot demonstrate that the key operations occurred outside Hong Kong. Common pitfalls include Hong Kong employees involved in overseas transactions, Hong Kong bank accounts used to receive payments, and business decisions made from Hong Kong. The IRD examines the substance of the operations, not just the form of the contracts.

Transfer pricing considerations arise when related parties are involved in cross-border transactions. The IRD may apply transfer pricing rules to ensure that profits are not artificially shifted offshore. Maintain contemporaneous documentation to support transfer pricing positions.

• DIPN 21 is the IRD’s guidance on determining the locality of profits.
• The operation test examines where the essential profit-generating activities occur.
• Offshore profits are exempt from profits tax, but the taxpayer bears the burden of proof.
• The FSIE regime adds additional rules for MNE groups receiving foreign-sourced income in Hong Kong.
• Maintain clear records of overseas operations to support offshore claims.
