Hong Kong and the Mainland: Comparison of double tax treaty protections

Are you planning cross-border investments between Hong Kong and Mainland China? With billions in trade flowing between the two jurisdictions, understanding their double tax treaty protections can generate substantial tax savings for your business. While both jurisdictions offer treaty networks to prevent double taxation, their approaches differ significantly—choosing the right investment structure could mean the difference between paying 0% or 10% tax on your dividend income. Let's delve into how double taxation arrangements between Hong Kong and Mainland China differ in 2024.

Treaty Networks: Strategic Coverage vs. Global Network

Comprehensive Double Taxation Agreements are essential tools for businesses operating across borders, preventing the same income from being taxed twice. For companies navigating the complex tax environments of both Hong Kong and Mainland China, understanding their respective treaty networks is crucial for effective tax planning and compliance.

Hong Kong's Strategic Network

Hong Kong has established a strategic network of Comprehensive Double Taxation Agreements with over 45 tax jurisdictions. While fewer in number compared to Mainland China's network, Hong Kong's treaties are carefully selected to complement its role as an international financial center. These agreements primarily target major trading partners, investment destinations, and financial centers aligned with Hong Kong's economic priorities.

Mainland China's Extensive Global Network

Mainland China possesses one of the world's largest double taxation treaty networks, having signed comprehensive agreements with over 100 countries and territories worldwide. This extensive coverage offers wide-ranging treaty benefits for enterprises engaging with diverse international partners, reflecting China's status as a global economic powerhouse with widespread trade and investment ties.

Tax Residency: Proving Your Entitlement to Treaty Benefits

To enjoy the benefits of double taxation avoidance agreements, you must establish and prove your tax residency status. Hong Kong and Mainland China have fundamental differences in determining residency, reflecting their respective unique tax systems.

Hong Kong's Territorial Source Principle

Hong Kong adopts a territorial source principle, taxing only income sourced from Hong Kong. For treaty purposes, a company is considered a Hong Kong resident if it is incorporated in Hong Kong or if its central management and control are exercised in Hong Kong. An individual qualifies as a resident if they ordinarily reside in Hong Kong or stay in Hong Kong temporarily for a substantial period.

Mainland China's Worldwide Taxation Principle

Mainland China adopts a worldwide taxation principle. A company qualifies as a resident enterprise if it is incorporated in Mainland China or if the place of its "effective management and control" is located within Mainland China. An individual is considered a resident if they have a domicile in Mainland China, or reside in Mainland China for 183 days or more in a tax year.

Withholding Tax Rates: Where the Key Differences Lie

One of the most significant benefits of a Double Taxation Agreement is the reduction of withholding tax rates on cross-border payments. The differences between Hong Kong and Mainland China in this area are substantial and can have a major impact on investment structuring.

Dividends: 0% vs. 5–10%

This is where Hong Kong offers a major advantage. Under Hong Kong's territorial system of taxation, dividends paid by Hong Kong companies to non-resident shareholders are generally not subject to withholding tax. This 0% rate makes Hong Kong highly attractive for international holding structures.

In contrast, Mainland China levies a statutory withholding tax rate of 10% on dividends paid to non-resident enterprises. Under its Double Taxation Agreements, including the Arrangement between the Mainland of China and the Hong Kong Special Administrative Region for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with respect to Taxes on Income, this rate is typically reduced to:

• 5% – For recipients holding at least 25% of the capital of the paying company
• 10% – For other shareholders

Interest and Royalties: Applicable Treaty Reductions

Both jurisdictions impose withholding tax on interest and royalties paid to non-residents, and Double Taxation Agreements provide significant relief. Under the Arrangement between the Mainland of China and the Hong Kong Special Administrative Region for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with respect to Taxes on Income:

Double Taxation Relief: Exemption Method vs. Tax Credit Method

When income is subject to tax in two jurisdictions, both Hong Kong and Mainland China offer relief—but through fundamentally different mechanisms that carry significant implications for businesses.

Hong Kong's Exemption Method

Hong Kong primarily employs the exemption method to eliminate double taxation. Under this regime, foreign income that has already been taxed in the source jurisdiction (particularly under a double taxation agreement) may be exempt from tax in Hong Kong. This approach simplifies compliance, as complex foreign tax credit calculations are generally unnecessary.

Mainland China's Tax Credit Method

Mainland China generally adopts the tax credit method. This allows resident taxpayers to credit foreign taxes paid on the same income against their Mainland China tax liability. The credit is capped at the amount of Mainland China tax payable on that foreign-sourced income.

Practical Application: Real-World Business Scenarios

Let us examine how these differences manifest in common business scenarios:

Scenario 1: Intellectual Property Licensing

A Hong Kong company licenses software to a Mainland Chinese manufacturer. Without a DTA, Mainland China might apply its domestic royalty withholding tax rate (typically 10%). Under the Mainland-Hong Kong Arrangement, the rate is reduced to 7%. This means the Hong Kong company receives 93% instead of 90% of the royalty—a significant difference for high-value transactions.

Scenario 2: Holding Company Structures

A multinational enterprise establishes a regional holding company. If based in Hong Kong and holding at least 25% equity in a Mainland subsidiary, a 5% withholding tax applies on dividend distributions. If the holding company were in a non-treaty jurisdiction, the rate could be 10%. Over time, this 5% difference represents substantial tax savings.

Scenario 3: Cross-Border Financing

A Hong Kong bank extends a loan to a Mainland Chinese company. Interest paid from Mainland China to Hong Kong benefits from reduced withholding tax rates under the DTA (typically 7–10% instead of higher domestic rates). The Hong Kong bank can then exempt this interest income from Hong Kong tax under the exemption method.

Choosing between Hong Kong and Mainland China for your cross-border business is not merely a geographical consideration, but a matter of strategic tax planning. Hong Kong's 0% dividend withholding tax, territorial tax system, and exemption method offer highly attractive advantages for certain investment structures; whereas Mainland China's extensive treaty network and foreign tax credit method may be better suited for other situations. The optimal choice depends on your specific business model, target markets, and fund flows. As international tax rules such as Pillar Two continue to evolve, staying informed and seeking professional advice has never been more critical for enterprises operating between Hong Kong and the Mainland.
