Hong Kong 2026: Pillar Two, Transfer Pricing and Stablecoin Licensing

Hong Kong remains a major hub for international business, regional headquarters and cross-border trade. In 2026, its compliance environment brings together three important developments: the implementation of global minimum-tax reporting, established transfer-pricing documentation requirements and a more developed regulatory framework for stablecoins and virtual-asset services.

For multinational groups, regional operating companies and digital-asset businesses, these developments require different assessments. Pillar Two does not apply to every Hong Kong company, transfer-pricing documentation is subject to specific exemptions, and digital-asset licensing depends on the activity being performed. Understanding these distinctions is essential to designing an appropriate compliance approach.

1. Pillar Two has moved into practical implementation

Hong Kong enacted its minimum-tax legislation on 6 June 2025, introducing the Income Inclusion Rule (IIR) and Hong Kong Minimum Top-up Tax (HKMTT) for fiscal years beginning on or after 1 January 2025. The first phase of the Inland Revenue Department's Pillar Two Portal launched on 19 January 2026, enabling relevant entities to submit top-up tax notifications electronically.

The framework applies to multinational enterprise groups with annual consolidated revenue of at least EUR 750 million in at least two of the four fiscal years immediately preceding the relevant fiscal year. It is therefore a large-group regime, not a general replacement for Hong Kong's ordinary profits-tax system.

The mechanisms perform different functions:

The IIR can impose top-up tax on qualifying Hong Kong parent entities in respect of low-taxed entities outside Hong Kong.
The HKMTT applies to relevant low-taxed entities located or operating in Hong Kong, giving Hong Kong priority to collect the domestic top-up tax.
The Undertaxed Profits Rule is provided for in the legislation, but its implementation date is to be specified separately.

The 15% minimum is calculated under the OECD's Global Anti-Base Erosion framework on a jurisdictional basis. It is not simply a comparison between a company's headline corporate-tax rate and 15%. The calculation involves GloBE income, adjusted covered taxes, relevant exclusions and any applicable safe harbours.

For international groups, the practical starting point is to identify the entities within scope, establish their jurisdictional treatment and determine which group teams will provide the necessary financial and tax data.

2. Notification, return filing and electronic access require separate preparation

Hong Kong's Pillar Two framework distinguishes between notifying the IRD and submitting the substantive top-up tax return.

An annual top-up tax notification generally must be filed within six months after the end of the reporting fiscal year. The top-up tax return is generally due within 15 months, extended to 18 months for the group's first transition year.

A group may designate a Hong Kong constituent entity to perform certain local filing obligations on behalf of other relevant Hong Kong entities, subject to the statutory arrangements. Relief from submitting GloBE Information Return information locally may also be available where the required information is filed in a jurisdiction with an appropriate exchange arrangement. Hong Kong signed the multilateral competent authority agreement for the exchange of GloBE Information Returns (GIR MCAA) on 21 April 2026, which supports this relief in practice.

Digital access is an operational requirement, not merely an administrative detail. Relevant entities need the appropriate Business Tax Portal arrangements, group identification codes and authentication credentials to use the Pillar Two Portal. The IRD has scheduled a second phase of the Portal, covering the filing of top-up tax returns, for the fourth quarter of 2026. Appointing an adviser does not eliminate the need to establish clear internal responsibility for information and approvals.

Separately, mandatory electronic filing of profits-tax returns applies to relevant entities of in-scope multinational groups from year of assessment 2025/26 onwards, subject to the specified conditions and exceptions. This is distinct from the obligation to file top-up tax notifications and returns.

3. Transfer pricing remains a separate compliance obligation

Hong Kong's transfer-pricing documentation framework predates the 2026 developments. Master-file and local-file requirements apply to accounting periods beginning on or after 1 April 2018, subject to the applicable exemptions.

This distinction matters: a group outside the EUR 750 million Pillar Two threshold may still have Hong Kong transfer-pricing obligations. Businesses should assess the regimes separately rather than assume that one threshold determines all international tax requirements.

The documentation framework requires businesses to explain how value is created across the group, including the functions performed, assets used, risks assumed and contributions made by associated enterprises.

A master file provides a high-level overview of the group's operations, intangibles, intercompany financing and tax position. A local file focuses on material controlled transactions involving the Hong Kong entity and the analysis supporting their pricing.

For regional headquarters, financing companies, distributors, intellectual-property structures and cross-border service businesses, this means that contracts and pricing policies should be supported by the actual allocation of responsibilities and activities.

4. Documentation thresholds, deadlines and retention rules matter

A Hong Kong entity is exempt from preparing a master file and local file for an accounting period if it meets any two of the following conditions:

Revenue does not exceed HKD 400 million.
Total assets at the end of the period do not exceed HKD 300 million.
Average employee numbers do not exceed 100.

Separate transaction-based exemptions apply. A local file need not cover a controlled transaction category where its aggregate arm's-length amount does not exceed the relevant threshold:

HKD 220 million for transfers of movable or immovable property, excluding financial assets and intangibles.
HKD 110 million for transactions involving financial assets.
HKD 110 million for transfers of intangibles.
HKD 44 million for other transactions.

These thresholds apply to the aggregate amount within each category, without offsetting revenue and expense transactions against one another. Specified domestic transactions are subject to separate exemption rules.

Where documentation is required, the master file and local file must be prepared within nine months after the accounting period ends. They must be reviewed and updated annually and retained for at least seven years after the relevant period.

The files are not routinely submitted with the profits-tax return. However, the taxpayer must make the relevant declarations and have the documentation ready for submission when requested by the IRD. The Department conducts desk-based reviews addressing preparation, completeness, accuracy and compliance with deadlines, normally within six months after the return is filed. Failure to prepare the required files can lead to prosecution and a fine of up to HKD 50,000.

An exemption from preparing particular files should therefore be documented and supported, rather than treated as an assumption.

5. Stablecoin issuance is now a licensed activity

Hong Kong's Stablecoins Ordinance took effect on 1 August 2025, establishing an HKMA-administered licensing framework for regulated fiat-referenced stablecoin issuance. The framework moved further into implementation when the HKMA announced the granting of its first two stablecoin issuer licences on 10 April 2026.

The regime establishes requirements concerning reserve management, redemption, governance, risk management and anti-money-laundering and counter-financing-of-terrorism controls.

Among the principal safeguards:

The market value of the relevant reserve-asset pool must remain at least equal to the par value of the outstanding specified stablecoins.
Holders must have a right to redeem at par value.
Issuers must maintain arrangements supporting effective redemption and protection of the reserve assets.
Redemption conditions must be reasonable and not unduly burdensome.

For businesses considering stablecoin-based products or settlement arrangements, the regulatory assessment should identify their precise role. Issuing a stablecoin, distributing it, advising on it and providing other virtual-asset services are not interchangeable activities, and a licence for one function should not be assumed to authorise every related service.

6. Virtual-asset advisory and management proposals require careful classification

On 26 May 2026, the Financial Services and the Treasury Bureau and the Securities and Futures Commission published consultation conclusions on proposed licensing regimes for virtual-asset advisory and management service providers.

The proposals follow the principle of "same activity, same risks, same regulation". Their intended scope is aligned with the conventional securities framework for Type 4 activities, advising on securities, and Type 9 activities, asset management.

The proposed framework would regulate businesses providing advice on acquiring or disposing of virtual assets. A separate proposed regime would cover virtual-asset management services.

Importantly, consultation conclusions are not the same as an operative licensing regime. The authorities have indicated that they intend to introduce legislation to the Legislative Council. Until that legislation is enacted and commenced, the proposed requirements are not yet in force, and businesses should monitor the legislative process and any transitional arrangements.

Tokenisation likewise requires analysis of the underlying product and service. The relevant question is not simply whether blockchain technology is involved, but what rights the asset represents and what the business actually does.

7. Digital tax compliance does not mean mandatory e-invoicing

Hong Kong does not operate a general mandatory e-invoicing regime for ordinary commercial transactions. Electronic invoicing should not be confused with the separate mandatory electronic tax-filing requirements applicable to relevant multinational-group entities.

However, the absence of a general e-invoicing mandate does not remove record-keeping obligations.

Under section 51C of the Inland Revenue Ordinance, businesses must retain sufficient records in English or Chinese to enable assessable profits to be determined. These include accounting records, invoices, receipts, bank statements and supporting transaction records, and must generally be retained for at least seven years.

Electronic business records are recognised subject to the applicable requirements. Businesses therefore need systems that preserve the supporting evidence, allow records to be retrieved and maintain consistency between commercial transactions, accounting records and tax submissions.

For international groups, digital readiness means more than choosing invoicing software. It includes access controls, document retention, reconciliation and responsibility for supplying information to tax authorities.

What does this mean for international businesses?

Hong Kong's compliance landscape is not a single regime applying uniformly to every company. Large multinational groups must assess Pillar Two, related-party businesses must review transfer-pricing requirements and exemptions, and digital-asset operators must identify the regulatory treatment of each activity.

A coordinated review should address:

Whether the group meets the Pillar Two revenue threshold and which Hong Kong entities are affected.
Responsibility for notifications, returns, electronic access and supporting data.
Master-file and local-file requirements, exemptions and preparation deadlines.
Consistency between intercompany agreements, actual operations and pricing.
The distinction between licensed stablecoin issuance and other digital-asset activities.
Record retention and the separation between electronic invoicing and tax-return filing.

We help international clients coordinate:

Hong Kong company establishment and regional corporate structuring.
Pillar Two and minimum top-up tax assessments.
Transfer-pricing policies and supporting documentation.
Activity-specific regulatory assessments for stablecoins, tokenisation and virtual-asset services.
Tax, trade and legal requirements across Hong Kong and relevant regional markets, including mainland China, India and Bangladesh.

Hong Kong's evolving framework calls for structures that are commercially coherent, properly documented and matched to the activities being performed. For international businesses, aligning corporate decisions, tax reporting and regulatory analysis from the outset provides a stronger foundation for regional growth.
