For decades, Hong Kong has been recognised as one of the world’s most business-friendly tax jurisdictions. Its territorial profits tax system, competitive statutory rates, and longstanding policy stability have made it a preferred base for international investors and multinational enterprises.
As the global tax landscape evolves, Hong Kong has implemented two major reforms aligning its tax framework with international standards:
the Foreign-Sourced Income Exemption (FSIE) regime, and
the OECD BEPS 2.0 / Pillar Two global minimum tax framework, including the Hong Kong Minimum Top-Up Tax (HKMTT) and the Income Inclusion Rule (IIR), effective for fiscal years beginning on or after 1 January 2025.
While both reforms modernise Hong Kong’s tax architecture, they also mean that certain traditional tax planning approaches—particularly offshore profits claims and reliance on the 8.25% two-tier profits tax rate—no longer operate as they previously did, especially for large multinational enterprise groups.
This article outlines the principal changes and their implications for multinational groups and investors operating through Hong Kong under the evolving international tax framework.
Key Takeaways
Offshore profits claims remain valid under Hong Kong’s territorial tax system, but their tax advantage is reduced for large multinational groups.
Pillar Two introduces a global minimum effective tax rate of 15% for MNE groups (≥ EUR 750m revenue), meaning profits exempt in Hong Kong may still be subject to top-up tax elsewhere.
The 8.25% two-tier profits tax rate remains part of Hong Kong’s domestic regime, but for in-scope MNE groups its benefit may be neutralised by global minimum tax rules.
The FSIE regime changes the treatment of foreign-sourced passive income, which may be taxable in Hong Kong unless economic substance or other exemption conditions are satisfied.
Substance and operational evidence are increasingly important for both offshore claims and FSIE exemptions under the IRD’s current approach.
Offshore Profits Claims: Still Legally Valid, But Offering Reduced Benefit for Large MNE Groups
Hong Kong continues to apply the territorial source principle, under which only profits arising in or derived from Hong Kong are subject to profits tax. The Inland Revenue Department (IRD) confirms that profits generated from activities conducted wholly outside Hong Kong may still qualify for exemption from Hong Kong profits tax, subject to a source-of-profits analysis.
However, the practical tax benefit of offshore claims is materially reduced for multinational groups that fall within the scope of the Pillar Two rules.
Pillar Two Reduces the Benefit for In-Scope MNEs
Multinational enterprise groups with consolidated annual revenue of EUR 750 million or more must ensure that a minimum effective tax rate (ETR) of 15% is paid in each jurisdiction where they operate.
Hong Kong has implemented this requirement through:
- the Hong Kong Minimum Top-Up Tax (HKMTT), and
- the Income Inclusion Rule (IIR),
effective for fiscal years beginning on or after 1 January 2025.
This means:
- Even if Hong Kong accepts an offshore profits claim, resulting in no local profits tax liability,
- the multinational group may still be required to pay a top-up tax—either under Hong Kong’s HKMTT or under the parent jurisdiction’s IIR—to bring the jurisdictional ETR to 15%.
Accordingly, for large multinational groups:
- offshore claims remain legally available under domestic law, but
- they may no longer produce a net tax advantage, as the tax liability is effectively shifted into the global minimum tax framework.
Offshore Claims Remain Relevant for SMEs, But With Increased Scrutiny
For companies below the Pillar Two revenue threshold, offshore profits claims may still provide effective tax relief where supported by sufficient operational evidence. However, regulatory scrutiny has increased.
The IRD now places greater emphasis on:
- genuine commercial substance,
- contemporaneous documentation, and
- verifiable economic activities conducted outside Hong Kong.
This approach is consistent with recent IRD guidance and administrative practice concerning offshore claims and the interaction with the FSIE regime.
The 8.25% Two-Tier Profits Tax Rate: Limited Relevance for Pillar Two Groups
Hong Kong’s two-tier profits tax system imposes (for corporations):
- 8.25% on the first HK$2 million of assessable profits, and
- 16.5% on profits exceeding that threshold.
This structure remains fully applicable under Hong Kong domestic tax law.
However, the lower 8.25% rate no longer produces favourable tax outcomes for multinational enterprise groups that fall within the scope of Pillar Two.
Under the Pillar Two framework:
- Any jurisdictional effective tax rate below 15% may trigger a top-up tax,
- bringing the effective tax burden of Hong Kong entities up to the 15% minimum level.
Practical implication:
The 8.25% rate may continue to apply for domestic tax calculation purposes, but for in-scope MNE groups the economic benefit of the lower rate may be neutralised by the HKMTT or IIR mechanisms.
FSIE Regime: Foreign-Sourced Passive Income No Longer Automatically Exempt
The expanded Foreign-Sourced Income Exemption (FSIE) regime, effective from 2024, significantly changed the treatment of certain categories of foreign-sourced passive income, including:
- dividends
- interest
- disposal gains
- intellectual property (IP) income
Under the FSIE regime, such income may be subject to Hong Kong profits tax unless specific exemption conditions are satisfied, including the economic substance requirement applicable to certain entities.
As a result, structures that previously relied on routing passive income through Hong Kong entities without meaningful operational activity may no longer qualify for exemption.
The FSIE framework forms part of Hong Kong’s effort to align with international tax transparency and anti-avoidance standards while preserving its role as an international holding and financing centre.
What Has Fundamentally Changed
For multinational groups subject to Pillar Two (≥ EUR 750m revenue)
Certain traditional tax planning strategies may now be neutralised by the global minimum tax framework:
- Offshore profits claims → potential top-up tax to 15%
- 8.25% two-tier rate → potential top-up tax to 15%
- Low-ETR structures → reduced effectiveness
- Passive income exemptions → subject to substance requirements under FSIE
For all companies under the FSIE regime
Foreign-sourced passive income is no longer automatically exempt unless the taxpayer satisfies relevant exemption conditions, including:
- genuine economic substance,
- adequate personnel and operating expenditure, and
- effective management or decision-making functions located in Hong Kong.
For SMEs (below EUR 750m revenue)
Offshore profits claims remain available under Hong Kong’s territorial tax framework but require more substantial evidentiary support.
Hybrid or “form‑based” structures may face greater challenge from the IRD.
Why This Evolution May Strengthen Hong Kong’s Position
These reforms represent a maturing, internationally aligned tax system, not a loss of competitiveness. Hong Kong’s traditional appeal was never tax alone. Its enduring structural advantages remain powerful differentiators:
China Connectivity and Market Access
Hong Kong continues to serve as the leading gateway to Mainland China through enduring programs such as Stock Connect, Bond Connect, Swap Connect, and other cross‑border market access schemes.
Offshore Renminbi Financial Infrastructure
Hong Kong maintains the largest offshore RMB liquidity pool and supporting financial infrastructure, facilitating RMB-denominated settlement, financing, and asset management.
Established Legal and Regulatory Framework
Hong Kong’s legal system, regulatory institutions, and financial market infrastructure continue to provide a predictable operating environment for international investors.
Continued Simplicity of the Tax System
Despite recent reforms, several structural features of the Hong Kong tax system remain unchanged:
- no value-added tax (VAT) or goods and services tax (GST)
- no capital gains tax
- no withholding tax on dividends or interest
- comparatively low statutory corporate tax rates
Conclusion
Hong Kong’s tax system is evolving to meet global expectations.
Offshore profits claims and the 8.25% profits tax tier continue to exist under domestic law. However, their practical effectiveness has changed under the combined influence of Pillar Two global minimum tax rules and the FSIE regime.
For large multinational groups, these mechanisms may limit the tax advantages historically associated with certain structures. For SMEs, traditional territorial planning approaches remain available but are subject to stricter evidentiary and substance requirements.
Overall, Hong Kong’s new tax landscape is more transparent, more internationally aligned, and more resilient, supporting long‑term investor confidence while preserving the factors that have always made Hong Kong exceptional: unrivalled connectivity, deep capital markets, and a simple, trusted tax framework.
