Understanding Hong Kong’s Double Tax Treaties

Hong Kong is widely recognised for its business-friendly tax regime—low corporate tax rates, a territorial basis of taxation, and the absence of VAT, capital gains tax, and withholding tax on dividends and interest. However, for companies and individuals operating across borders, double taxation remains a potential concern.

To address this, Hong Kong has established a growing network of Comprehensive Double Taxation Agreements (CDTAs) with key global trading partners. These treaties are designed to eliminate the risk of being taxed twice on the same income and to foster cross-border investment and economic cooperation.

This article provides a practical overview of Hong Kong’s double tax treaty network, how CDTAs work, and how businesses can benefit from treaty protection.

What Is a Double Tax Treaty?

A double tax treaty, also known as a comprehensive double taxation agreement, is a bilateral agreement between two jurisdictions. Its main objective is to prevent income from being taxed twice, once in the source country where the income is generated and again in the resident country of the taxpayer.

Hong Kong’s treaties typically follow the OECD Model Tax Convention but are tailored to reflect Hong Kong’s own territorial taxation system.

Key Benefits of Hong Kong’s Double Tax Treaties

Avoidance of Double Taxation A CDTA allocates taxing rights between Hong Kong and the treaty partner, ensuring that taxpayers are not subject to tax in both places on the same income. Common forms of income protected include business profits, dividends, interest, royalties, and employment income.

Reduced Withholding Tax Rates Many jurisdictions impose withholding taxes on cross-border payments. A CDTA may lower these rates significantly for Hong Kong residents. For example, dividends paid to a Hong Kong company may be taxed at a reduced rate of 5% or even 0%, depending on the treaty and shareholding percentage.

Tax Certainty and Transparency Treaties include definitions of permanent establishment, residency, and profit attribution. This helps taxpayers understand where and how they will be taxed, reducing the risk of disputes or surprises.

Mutual Agreement Procedures (MAP) In cases where double taxation still arises, CDTAs provide a dispute resolution mechanism called a Mutual Agreement Procedure, allowing the competent authorities of both countries to resolve the issue in a cooperative, structured manner.

Exchange of Information and Anti-Tax Avoidance Measures While historically known for tax confidentiality, Hong Kong’s treaties now include Exchange of Information (EOI) provisions in line with international standards. This enhances transparency and ensures treaties are used for genuine business purposes.

Countries with Which Hong Kong Has Signed Double Tax Treaties

As of 2025, Hong Kong has signed over 45 CDTAs, covering major trading and investment partners across Asia, Europe, Oceania, the Middle East, and Africa. Key treaty partners include:

• Mainland China

• Singapore

• United Kingdom

• France

• Germany

• Japan

• Thailand

• Australia

• United Arab Emirates

• Luxembourg

• India

• Vietnam

• South Korea

• Malaysia

The treaty with Mainland China is particularly important for businesses operating across the border, offering preferential tax treatment and clarity on permanent establishment rules.

A complete and regularly updated list of CDTAs is available on the Hong Kong Inland Revenue Department (IRD) website.

How Businesses Can Benefit from a CDTA

For Hong Kong-based businesses with overseas clients, suppliers, or operations, using the correct CDTA can reduce foreign withholding taxes on:

• Dividend payments from overseas subsidiaries

• Interest received from foreign bank accounts or bonds

• Royalties for IP licensed abroad

• Professional or consulting services rendered overseas

Similarly, foreign investors in Hong Kong can enjoy reduced tax exposure in their home jurisdictions when profits are repatriated—provided that the income qualifies under the relevant treaty.

To benefit, companies typically need to obtain a Hong Kong Certificate of Resident Status (CoR) from the IRD. This document confirms tax residency and must be presented to the foreign tax authority or withholding agent. The CoR application must be supported by valid substance in Hong Kong, such as local management, staff, or physical premises.

Practical Considerations and Limitations

While CDTAs offer clear advantages, the following should be considered:

• Not all countries have treaties with Hong Kong

• Tax residency and beneficial ownership must be clearly demonstrated

• Treaty abuse provisions (such as Limitation on Benefits clauses) are increasingly common

• Domestic anti-avoidance rules in both jurisdictions may override treaty relief in certain cases

It is critical to evaluate each treaty on a case-by-case basis to ensure eligibility and compliance.
