Imagine raising HK$1 billion through a “blank cheque” company, then merging with a promising tech startup to create a publicly listed entity worth billions. This is the world of Special Purpose Acquisition Companies (SPACs), and Hong Kong has positioned itself as Asia’s premier destination for these innovative listing vehicles. But what are the tax implications, particularly regarding Hong Kong’s stamp duty regime? This comprehensive guide breaks down everything you need to know about SPACs and their tax treatment in Hong Kong’s dynamic financial landscape.

Understanding Hong Kong’s SPAC Framework

Hong Kong introduced its SPAC listing regime on January 1, 2022, establishing Chapter 18B of the Listing Rules to create a structured framework for these innovative vehicles. Unlike traditional IPOs where operating companies list directly, SPACs offer a two-stage pathway to public markets: first, the shell company raises capital through an IPO, then it identifies and merges with a target operating company within a defined timeframe.

Hong Kong’s Stringent SPAC Requirements

The Hong Kong Stock Exchange (HKEX) has established one of the most rigorous SPAC regimes globally, emphasizing quality, investor protection, and market integrity. Here are the key requirements:

Hong Kong Stamp Duty Fundamentals

Hong Kong’s Stamp Duty Ordinance requires payment of stamp duties on transfers of shares in Hong Kong-incorporated companies and Hong Kong-listed shares. The duty applies to beneficial ownership transfers, not merely legal title changes. Understanding these rules is crucial for SPAC participants.

Current Stamp Duty Rates (Effective November 17, 2023)

Note: This rate was reduced from 0.13% per party (0.26% total) effective November 17, 2023, following the Chief Executive’s 2023 Policy Address.

What Triggers Stamp Duty?

Stamp duty is triggered by the transfer of beneficial ownership in Hong Kong stock, which includes:

• Stock in companies incorporated in Hong Kong (regardless of listing location)
• Stock listed on the Hong Kong Stock Exchange (regardless of incorporation jurisdiction)
• Shares where the register of members must be maintained in Hong Kong

Stamp Duty Implications for SPAC Transactions

Stage 1: SPAC IPO and Initial Share Issuance

The initial subscription of SPAC shares during the IPO does not typically trigger stamp duty obligations, as this represents a new issuance of shares rather than a transfer of existing shares.

Stage 2: The De-SPAC Transaction

The de-SPAC transaction—where the SPAC merges with or acquires an operating target company—presents complex stamp duty considerations. The HKEX treats every de-SPAC transaction as a deemed new listing application, but stamp duty treatment depends on the specific structure employed.

Warrants and Exercise Events

SPAC structures typically include warrants issued to both public shareholders and promoters. Understanding the stamp duty treatment is essential:

1. Initial Grant of Warrants: No stamp duty on initial issuance of SPAC warrants or promoter warrants
2. Exercise of Warrants: Stamp duty applies when exercised (0.2% of exercise price or market value, whichever higher)
3. Strategic Timing: Consider exercising warrants when share price is lower to reduce stamp duty base

Practical Tax Planning Strategies

1. Structure Selection and Optimization

The de-SPAC transaction structure significantly impacts stamp duty exposure. Consider these approaches:

• Offshore Target Structures: If the target is incorporated outside Hong Kong and not Hong Kong-listed, share exchange may avoid stamp duty
• Asset vs. Share Acquisition: Acquiring business assets rather than shares may avoid stamp duty (though may trigger other considerations)
• Proper Documentation: Ensure arrangements have commercial substance and aren’t primarily for stamp duty avoidance

2. Cross-Border Tax Coordination

For international de-SPAC transactions, coordinate Hong Kong stamp duty with tax obligations in other jurisdictions:

• Identify whether target jurisdiction imposes transfer taxes
• Consider double taxation relief or foreign tax credits
• Evaluate treaty benefits if applicable
• Structure to minimize aggregate global tax leakage

Additional Tax Considerations for SPAC Participants

Profits Tax on Trading Gains

While Hong Kong does not impose capital gains tax, profits from trading activities are subject to profits tax. The distinction is crucial:

Foreign-Sourced Income Exemption (FSIE) Regime

Since January 1, 2023, Hong Kong’s refined FSIE regime has significant implications for SPAC participants:

• Specified Foreign-Sourced Income includes dividends, interest, and disposal gains from equity interests
• Income received in Hong Kong by corporate taxpayers is deemed Hong Kong-sourced and taxable unless exemption conditions met
• Economic substance test requires adequate employees, operating expenditure, and physical office in Hong Kong
• Participation exemption available for qualifying equity holdings (generally 5%+ held for 12+ months)

Comprehensive Case Study: Asia Technology Acquisition Corp

Let’s examine a hypothetical SPAC transaction to understand the practical stamp duty implications:

Hong Kong’s SPAC regime represents a sophisticated balance between innovation and investor protection, with stamp duty considerations playing a crucial role in transaction structuring. As the market evolves with regulatory reforms like the HK$500 million PIPE cap and enhanced accessibility measures, understanding these tax implications becomes increasingly important for sponsors, investors, and target companies alike. With proper planning and professional guidance, SPAC transactions can be structured efficiently while complying with Hong Kong’s tax and regulatory requirements.
