Key Points of the Hong Kong Tax System Foreign Businesses Must Know

Territorial Source Principle of Taxation

Hong Kong adopts the territorial source principle of taxation, meaning that only profits arising in or derived from Hong Kong are subject to Profits Tax. While the principle is straightforward, its application in specific cases can be highly contentious and frequently becomes the source of disputes between foreign businesses and the Inland Revenue Department (IRD).

For trading companies, the IRD applies the "contract effectuation test":

• Both contracts effected in Hong Kong: If both the purchase and sale contracts are effected in Hong Kong, the profits are taxable.
• Both contracts effected overseas: If both contracts are effected outside Hong Kong, the profits are non-taxable.
• Mixed scenario: If either the purchase contract or the sale contract is effected in Hong Kong, the profits are prima facie taxable.

Foreign Source Income Exemption (FSIE) Regime

Effective from January 1, 2023, Hong Kong's FSIE regime has fundamentally changed the way multinational enterprise (MNE) groups handle specific foreign-sourced income. The regime's scope was expanded on January 1, 2024 (FSIE 2.0) to align with EU requirements.

Key Points of the FSIE Regime:

• Covered Income Types: Applies to foreign-sourced dividends, interest, intellectual property income, equity disposal gains, and other asset disposal gains.
• Economic Substance Requirements: To maintain tax exemption, Hong Kong entities must demonstrate adequate economic substance by satisfying the economic substance requirement (ESR), participation exemption requirement, or nexus requirement.
• Deeming Provisions: Foreign-sourced income "received in Hong Kong" by an MNE entity will be deemed to arise in or derive from Hong Kong and be subject to tax, unless exempt conditions are met.
• Source Test Unchanged: The territorial source principle remains unchanged; the FSIE regime only applies to income that has already been determined to be offshore/foreign-sourced.

Common Tax Dispute Issues for Foreign Entrepreneurs

1. Rejection of Offshore Profits Claims

The IRD has adopted an increasingly rigorous approach when reviewing offshore profits claims. Common challenges include:

• Agency Arrangements: If key decisions are made in Hong Kong, profits may not be considered offshore-sourced even if agents conduct activities outside Hong Kong.
• Substance over Form: The IRD scrutinizes the economic substance of transactions, rather than just contractual arrangements.
• Related Party Transactions: Transactions with related parties are subject to stricter scrutiny.
• Insufficient Documentation: Lack of adequate evidence supporting the place where contracts were effected.

2. FSIE Economic Substance Disputes

With the FSIE regime coming into effect, disputes are emerging around:

• Whether the Hong Kong entity has "adequate" employees and operating expenditures to meet economic substance requirements.
• Whether Core Income Generating Activities (CIGA) are conducted in Hong Kong.
• Proper documentation and contemporaneous records regarding economic substance.
• Whether income is indeed "received in Hong Kong."

Hong Kong Tax Dispute Resolution Process: A Step-by-Step Breakdown

Stage 1: Lodging an Objection with the Inland Revenue Department

Key Deadline

You must submit a written objection within one month of the date of issue of the Notice of Assessment. This deadline is strictly enforced. Late objections are rarely accepted unless you can prove:

• Absence from Hong Kong
• Sickness
• Other reasonable causes preventing timely submission

How to Submit

Submit a notice of objection using Form IR831 (Notice of Objection / Application for Revision of Assessment). The objection must:

• Be in writing: Complete the relevant sections of Form IR831, or submit a detailed letter.
• State specific grounds: Clearly explain the specific legal and factual grounds on which the objection is based.
• Enclose supporting documents: Attach all relevant documentary evidence.
• Be properly submitted: Can be submitted by post (P.O. Box 28777, Concorde Road Post Office, Hong Kong), fax (2877 1232), or via your eTAX account.

Tax Payment Arrangements During Objection

Hong Kong follows the "pay first, dispute later" principle. You must pay the tax by the due date specified on the notice of assessment unless the Commissioner agrees to a holdover of tax. An application for holdover of tax must:

• Submit a written application explaining why the holdover of tax should be granted.
• Provide evidence supporting that your grounds of objection have reasonable prospects of success.
• The Commissioner has the discretion to grant full, partial, or no holdover.
• If granted, the held-over tax may be subject to interest, with an interest rate of 8.25% effective from July 2025.

Stage 2: Appeal to the Board of Review

If you disagree with the Commissioner's determination, you may appeal to the Board of Review (BOR), an independent statutory body separate from the Inland Revenue Department.

Lodging an Appeal

You must lodge an appeal within one month after receiving the Commissioner's written determination. The notice of appeal must include:

• A copy of the Commissioner's written determination (including reasons and statement of facts)
• A statement of all grounds of appeal
• Be served on both the Clerk to the Board of Review and the Commissioner

Address: Clerk to the Board of Review, 15/F, Inland Revenue Centre, 5 Concorde Road, Kai Tak, Kowloon, Hong Kong

Practical Strategies for Foreign Entrepreneurs

1. Maintain Comprehensive Documentation: The burden of proof lies with you. From the outset, thoroughly document contract execution, decision-making locations, economic substance activities, and transfer pricing documentation.
2. Engage Local Tax Professionals Early: Foreign entrepreneurs should engage Hong Kong tax professionals (accountants and tax lawyers) at the earliest stage to obtain structuring advice, compliance support, and objection preparation.
3. Consider Advance Rulings for Uncertain Matters: If your business model, offshore profit claim, or FSIE compliance position is uncertain, an advance ruling can provide binding certainty before finalizing the structure.
4. Respond Promptly to IRD Inquiries: The IRD frequently issues inquiry letters requesting information regarding offshore claims, FSIE compliance, or transfer pricing. These are often precursors to the issuance of additional assessments.
5. Evaluate Settlement Opportunities: At the administrative level (prior to the Board of Review), the IRD may be open to settlement discussions. Pragmatically assess the strength of your position.
6. Understand the "Pay First, Dispute Later" Principle: Cash flow planning is critical because you must generally pay the assessed tax during the dispute period. Budget for potential tax outlays during the dispute.
7. Stay Abreast of Regulatory Developments: With the refinement of the FSIE regime, intensified transfer pricing enforcement, and the implementation of the global minimum tax in 2025, Hong Kong's tax environment is rapidly evolving.

Latest Developments and Trends (2024-2025)

Implementation of Global Minimum Tax

Hong Kong passed the OECD's Global Minimum Tax framework (Pillar Two) on June 6, 2025, effective from January 1, 2025. Key aspects include:

• Tax Rate: 15% minimum effective tax rate
• Scope: MNE groups with consolidated revenue of EUR 750 million or more
• Includes: Income Inclusion Rule (IIR) and Hong Kong Minimum Top-up Tax (HKMTT)

Navigating Hong Kong tax disputes requires strategic planning, meticulous documentation, and professional guidance. While the process can be lengthy and complex, understanding your rights, obligations, and available mechanisms will significantly improve the chances of a favorable outcome. Remember, prevention through proper structuring and compliance is always more effective than remediation through dispute resolution.
