Green and Sustainable Finance Grant Scheme

The Green and Sustainable Finance Grant Scheme (GSF Grant Scheme) represents Hong Kong's flagship initiative to promote sustainable debt issuance. Launched in May 2021 and extended in the 2024-25 Budget, this scheme provides direct subsidies for costs associated with issuing green and sustainable bonds and loans in Hong Kong.

Extension and Expansion (2024-2027)

The Financial Secretary announced in the 2024-25 Budget a three-year extension of the GSF Grant Scheme through 2027, with a critical expansion to include transition bonds and loans. This enhancement, which took effect on 10 May 2024, acknowledges that certain carbon-intensive industries require transitional financing mechanisms as they progress toward decarbonization.

The scheme's expansion reflects Hong Kong's strategic positioning as a transition financing platform for the Greater Bay Area and broader Asian region, where many industries are in various stages of their sustainability journey.

Eligible Costs and Subsidy Structure

The GSF Grant Scheme provides subsidies across two distinct categories:

Category	Eligible Costs	Applicable To
Category 1	General bond issuance costs including legal fees, arrangement fees, and stock exchange listing fees	Bonds only
Category 2	Pre-issuance and post-issuance external review costs (third-party opinions, verification, certification)	Both bonds and loans

Since inception, the government has provided subsidies for over 340 eligible green and sustainable debt instruments totaling approximately US$100 billion. This substantial volume demonstrates the scheme's effectiveness in catalyzing Hong Kong's green finance market.

Market Performance and Impact

The scheme has contributed to remarkable market growth. In 2024, Hong Kong saw the issuance of over US$43.1 billion in green, social, sustainability, and sustainability-linked (GSS+) bonds, representing a 43.2% year-on-year increase. Hong Kong captured 45% of Asia's international GSS+ bond market in 2024, cementing its position as the region's leading green finance center.

Looking ahead, the 2025-26 Budget targets annual issuances of HK$150-195 billion under the Government Green Bond Programme and Infrastructure Bond Programme through 2030, signaling continued government commitment to sustainable finance development.

Unified Fund Exemption and ESG Investments

The Unified Fund Exemption (UFE) regime provides profits tax exemption for qualifying funds on specified transactions in qualifying assets. Recent enhancements announced in November 2024 significantly broaden the scope of ESG-related investments eligible for tax exemption.

Expanded Qualifying Investments for ESG Assets

The Financial Services and the Treasury Bureau (FSTB) issued a consultation paper on 25 November 2024 proposing substantial enhancements to the UFE regime. The consultation closed on 3 January 2025, with implementation targeted for the year of assessment 2025/26, subject to Legislative Council approval in 2026.

Key ESG-related expansions include:

• Emission derivatives and emission allowances: These instruments support carbon trading and decarbonization strategies, directly facilitating climate action investments.
• Carbon credits: As Hong Kong develops its Core Climate carbon marketplace, the inclusion of carbon credits as qualifying investments positions funds to participate in global carbon trading while benefiting from tax exemption.
• Insurance-linked securities: These instruments often incorporate climate risk considerations, expanding ESG investment opportunities.
• Immovable property outside Hong Kong: This allows funds to invest in green buildings and sustainable real estate projects internationally.
• Virtual assets (with restrictions): Virtual assets covered under the Anti-Money Laundering and Counter-Terrorist Financing Ordinance are eligible, except those referencing underlying assets other than qualifying investments.

Removal of the 5% Incidental Income Threshold

Previously, incidental income exceeding 5% of a fund's total income could disqualify the fund from profits tax exemption. This restriction particularly disadvantaged private credit funds and fixed income funds with substantial incidental income.

The proposed reforms eliminate this threshold entirely. Under the new framework, all income derived from qualifying investments will be eligible for profits tax exemption, regardless of whether it arises from qualifying or incidental transactions. This change significantly enhances flexibility for ESG funds with diversified income streams.

Expansion to Pension Funds and Endowment Funds

The consultation proposes expanding the UFE to cover pension funds and endowment funds, which were previously excluded due to not meeting pooling requirements. This expansion is particularly relevant for ESG investing, as institutional investors like pension funds increasingly incorporate sustainability criteria into their investment mandates.

New Requirements for Tax Exemption

To align with OECD substance requirements and maintain Hong Kong's international tax compliance reputation, the reforms introduce new obligations:

Requirement	Details	Rationale
Substantial Activities	Minimum 2 qualified individuals employed in Hong Kong Minimum HK$2 million annual operating expenses	Demonstrates genuine economic substance in Hong Kong
Tax Reporting	Annual profits tax return filing with the Inland Revenue Department (IRD)	Ensures accountability and regulatory compliance
ESG Assessment	Annual assessment of how ESG-focused funds have attained their ESG objectives	Prevents greenwashing and ensures genuine ESG focus

While the HK$2 million expense threshold may challenge smaller funds, it reflects global standards and helps protect Hong Kong's reputation as a well-regulated financial center. The ESG assessment requirement is particularly significant, as it mandates substantive documentation of ESG achievement rather than merely aspirational statements.

Qualifying Debt Instrument Scheme for Green Bonds

The Qualifying Debt Instrument (QDI) scheme, introduced in 1996, provides concessionary tax treatment on interest income and trading profits derived from qualifying debt instruments. Green bonds and sustainable bonds issued in Hong Kong can qualify under this scheme, making them attractive to both issuers and investors.

Tax Benefits Under the QDI Scheme

The QDI scheme offers two primary tax advantages:

1. Concessional tax rate on interest income: Non-resident investors receiving interest from QDIs are exempt from Hong Kong profits tax, while resident investors may benefit from preferential treatment depending on their circumstances.
2. Exemption on trading profits: Profits from trading QDIs may qualify for tax exemption under specified conditions.

For green bonds to qualify as QDIs, they must meet certain criteria including minimum issuance amount, maturity period, and documentation requirements. The Hong Kong Monetary Authority (HKMA) maintains detailed guidance on QDI eligibility.

Integration with the Green and Sustainable Finance Grant Scheme

Issuers can benefit from both the QDI tax concessions and the GSF Grant Scheme subsidies, creating a powerful combined incentive. An issuer might receive:

• Subsidies for external review costs and issuance expenses through the GSF Grant Scheme
• Tax concessional treatment for investors through QDI status
• Enhanced marketability due to Hong Kong's recognized green finance framework

This dual benefit structure makes Hong Kong particularly competitive for green bond issuance compared to other Asian financial centers.

Digital Bond Grant Scheme

Launched in 2024, the Digital Bond Grant Scheme represents Hong Kong's commitment to financial innovation and technology adoption in sustainable finance. The scheme offers issuers up to HK$2.5 million per eligible digital bond issuance.

ESG Applications of Digital Bonds

Digital bonds utilizing distributed ledger technology (DLT) offer several advantages for ESG investments:

• Enhanced transparency: Blockchain-based records provide immutable documentation of fund usage for green projects
• Improved tracking: Smart contracts can automate verification that bond proceeds are used for specified environmental projects
• Reduced costs: Digital issuance can lower transaction costs, making smaller green projects more financially viable
• Increased accessibility: Fractional ownership through tokenization can democratize access to green investments

The grant covers costs associated with digital bond issuance including technology implementation, legal advisory, and regulatory compliance. This incentive positions Hong Kong at the forefront of digital green finance innovation.

Tax Deductions for Environmental Technology and Vehicles

Beyond financial instruments, Hong Kong offers direct tax deductions for businesses investing in environmental technology and green transportation.

Environment-Friendly Vehicles Capital Expenditure Deduction

Since 18 June 2010, businesses purchasing eligible environment-friendly vehicles may claim 100% capital expenditure deduction under profits tax in the year of purchase. This accelerated deduction significantly improves cash flow compared to standard depreciation allowances.

Eligible Vehicles

Vehicle Type	Eligible Categories	Tax Treatment
Electric Vehicles (EVs)	All commercial electric vehicles including taxis, goods vehicles, buses, special purpose vehicles	100% deduction in year of purchase; no EPD verification required
Hybrid Electric Vehicles	Commercial hybrid vehicles meeting specified emissions standards	100% deduction in year of purchase; no EPD verification required
Other Environment-Friendly Vehicles	Vehicles certified by Environmental Protection Department under specific schemes	100% deduction with EPD certificate

Key Considerations

• Retroactive application: The deduction applies to eligible vehicles purchased before 18 June 2010 if still in business use
• Second-hand vehicles: Buyers of second-hand environment-friendly vehicles qualify for deduction if the vehicle meets eligibility criteria at time of purchase
• Hire-purchase exclusion: Vehicles acquired under hire-purchase arrangements are not eligible for the 100% deduction but remain eligible for standard depreciation allowances
• Documentation: Taxpayers should retain vehicle certificates and purchase documentation for IRD filing purposes

First Registration Tax Concessions

Complementing the profits tax deduction, Hong Kong offers First Registration Tax (FRT) reductions for environment-friendly commercial vehicles. Since 1 April 2008, buyers of newly registered environment-friendly commercial vehicles have enjoyed FRT reductions, with the qualifying standards updated effective 1 April 2025.

The 2024-25 Budget extended FRT concessions for electric vehicles by two years, though with a 40% reduction in concession amount to reflect decreasing EV prices and increased market availability. However, for electric commercial vehicles, electric motorcycles, and electric motor tricycles, FRT continues to be waived in full for two years.

Environmental Protection Machinery and Installations

Businesses investing in environmental protection machinery receive 100% capital expenditure deduction, similar to the treatment of manufacturing machinery and computer equipment. Qualifying expenditures include:

• Pollution control equipment
• Waste treatment facilities
• Energy-efficient installations
• Renewable energy generation equipment
• Water conservation systems

This deduction enables businesses to recover the full cost of environmental investments immediately through tax savings, substantially reducing the effective cost of going green.

Hong Kong Taxonomy for Sustainable Finance

In May 2024, the Hong Kong Monetary Authority released the Hong Kong Taxonomy for Sustainable Finance, a critical framework that defines eligible activities for sustainable finance classification. While not strictly a tax incentive, the Taxonomy has important implications for accessing ESG tax benefits.

Framework Structure

The Hong Kong Taxonomy currently defines 12 economic activities across four sectors, drawing on key global frameworks including:

• Common Ground Taxonomy (CGT)
• European Union Taxonomy
• Mainland China Taxonomy
• ASEAN Taxonomy
• Climate Bonds Taxonomy

This multi-jurisdictional alignment positions Hong Kong as a bridge between Asian and global sustainable finance markets, facilitating cross-border ESG investment flows.

Tax Implications

The Taxonomy serves several tax-relevant functions:

1. Eligibility determination: Many tax incentives require demonstration that investments qualify as "green" or "sustainable." The Taxonomy provides objective criteria for this determination.
2. Compliance verification: For funds claiming ESG-focused tax exemptions, the Taxonomy offers a recognized framework for annual ESG assessment requirements.
3. Documentation standards: Taxonomy alignment can streamline documentation for GSF Grant Scheme applications and QDI certifications.

Businesses and investors should ensure their ESG activities align with Taxonomy definitions to maximize access to available tax incentives and avoid challenges during IRD reviews.

Climate-Related Disclosure Requirements and Tax Planning

Hong Kong has mandated climate-related disclosures for listed companies aligned with the Task Force on Climate-related Financial Disclosures (TCFD) recommendations, with full implementation required by 2025. These disclosure requirements intersect with tax planning in important ways.

Integration of Tax and Climate Strategy

Companies preparing TCFD disclosures should integrate tax incentive planning into their climate strategies:

• Capital allocation decisions: TCFD climate risk assessments may identify opportunities for environment-friendly vehicle investments or green technology upgrades that qualify for tax deductions
• Green finance strategy: Climate transition plans may require capital raising, which could be optimized through green bond issuances utilizing the GSF Grant Scheme and QDI benefits
• Carbon pricing considerations: While Hong Kong has not yet implemented a carbon tax, companies should model potential carbon pricing impacts alongside available tax incentives for emissions reduction investments

Documentation Synergies

The documentation prepared for TCFD compliance can often support tax incentive applications:

• Greenhouse gas emissions data supports environment-friendly vehicle deduction claims
• Climate risk assessments inform green bond use-of-proceeds frameworks
• Sustainability governance structures demonstrate ESG fund management capabilities for UFE substantial activities requirements

Global Minimum Tax and ESG Fund Exemptions

Hong Kong has implemented domestic legislation for the OECD's Global Anti-Base Erosion (GloBE) rules under Pillar Two, with the Income Inclusion Rule and Hong Kong Minimum Top-up Tax taking effect for fiscal years beginning on or after 1 January 2025.

Investment Fund Carve-Out

To maintain Hong Kong's competitive position as a fund domicile, investment funds and insurance businesses are exempt from the Hong Kong Minimum Top-up Tax (HKMTT). This exemption applies regardless of whether the fund focuses on ESG investments or conventional assets.

The exemption is particularly valuable for ESG funds because:

• ESG funds often have complex international structures involving multiple jurisdictions
• Without the exemption, global minimum tax could apply at 15%, substantially increasing the effective tax rate beyond Hong Kong's preferential fund regimes
• The exemption allows ESG funds to maintain tax efficiency while meeting increasingly stringent sustainability requirements

Strategic Considerations

Fund managers should consider the interaction between global minimum tax rules and Hong Kong's ESG incentives:

1. Substance requirements: The UFE reforms' substantial activities requirements (2 qualified employees, HK$2 million expenses) may also support OECD substance standards, reducing global minimum tax exposure in other jurisdictions
2. Qualified refundable tax credits: Some ESG-related grants and subsidies may qualify as refundable tax credits under GloBE rules, potentially affecting effective tax rate calculations for non-exempt entities
3. Documentation coordination: Maintaining comprehensive records for both ESG tax incentive claims and global minimum tax compliance can create administrative efficiencies

Strategic Tax Planning for ESG-Focused Businesses

Maximizing Hong Kong's ESG tax incentives requires strategic planning that integrates tax efficiency with genuine environmental and social objectives.

Multi-Incentive Optimization

Sophisticated tax planning should layer multiple incentives:

Business Activity	Applicable Incentives	Combined Benefits
Green bond issuance for renewable energy project	GSF Grant Scheme subsidy QDI tax concessions Digital Bond Grant (if applicable)	Reduced issuance costs, tax-efficient investor returns, technology grant up to HK$2.5M
ESG fund investing in carbon credits and green tech	UFE profits tax exemption HKMTT exemption Expanded qualifying investments	Zero Hong Kong profits tax on qualifying transactions, no minimum top-up tax, broad investment scope
Company upgrading delivery fleet to EVs	100% capital expenditure deduction FRT waiver Two-tier profits tax rates	Immediate tax deduction, reduced acquisition cost, concessional rates on resulting profits
Manufacturing facility installing green technology	Environmental protection machinery deduction Green Tech Fund grants Potential green financing	100% tax deduction, possible grant funding, favorable financing terms

Timing Considerations

Tax planning should account for implementation timelines:

• UFE reforms: Targeted for year of assessment 2025/26, subject to Legislative Council approval in 2026. Businesses should prepare documentation and structures in advance.
• GSF Grant Scheme: Currently operational through 2027. Applications should be submitted promptly to secure subsidies for planned green issuances.
• Environment-friendly vehicle deductions: Currently available with no announced termination date. Capital expenditure timing can be optimized around company profit forecasts.
• TCFD compliance: Full implementation required by 2025. Early compliance can inform ESG tax strategy development.

Risk Management

ESG tax planning should incorporate risk mitigation:

1. Greenwashing avoidance: Ensure substantive ESG activities underpin tax claims. The annual ESG assessment requirement for funds demonstrates regulatory focus on genuine sustainability.
2. Documentation rigor: Maintain comprehensive records supporting ESG classifications, particularly for investments claiming alignment with the Hong Kong Taxonomy.
3. Regulatory change monitoring: ESG tax policy is evolving rapidly. Regular review of legislative developments ensures continued compliance and optimization.
4. Transfer pricing considerations: For multinational groups, ensure ESG-related transactions between related parties reflect arm's length terms to avoid transfer pricing challenges.
