How Offshore Payment Processors Affect the Source of Your Hong Kong Profits Tax Liability

Offshore Payment Processors and Hong Kong Profits Tax

A server outside Hong Kong does not make processing profits offshore. Payment processors operating in Hong Kong often assume it does. The Inland Revenue Department (IRD) has addressed this directly in Departmental Interpretation and Practice Note 39 (DIPN 39). Paragraph 17 of DIPN 39 states that although payment processing operations may be automated and carried out using a server located outside Hong Kong, "this fact does not, of itself, lead to the conclusion that the source of profits is located outside Hong Kong." The question of whether offshore payment processors Hong Kong profits tax applies depends on where the core operations that produce the profits are carried out, not on server location alone.

Territorial Source Principle and Payment Processors

Hong Kong taxes profits arising in or derived from Hong Kong under the territorial source principle. Profits sourced outside Hong Kong are not chargeable, whatever the residence of the taxpayer. The IRD's guidance on locality of profits is set out in DIPN 21. DIPN 39 paragraph 14 confirms that guidance is equally applicable to e-commerce. Section 14 of the Inland Revenue Ordinance (Cap. 112) charges profits tax where three conditions are met: the person carries on a trade, profession or business in Hong Kong; the profits are from that trade, profession or business; and the profits arise in or are derived from Hong Kong. For a payment processor, the critical question is the third condition: where do the profits arise?

DIPN 39 and E-Commerce Profits Source in Hong Kong

DIPN 39 addresses the source of profits from e-commerce activities, including payment processing. Paragraph 17 lists four things a server may be used for: giving information about products, processing online purchase orders, processing payments, and delivering digitised products. The Commissioner's stated view is that "the location of the server alone does not determine the locality of the profits." The proper approach is to focus on the core operations that effected the transaction and the place where those operations were carried out, "rather than on what has been done electronically." A payment processor cannot rely on a server in Singapore or the United States to support an offshore claim if the effective causes of the profit occur in Hong Kong.

Hong Kong Profits Tax Payment Gateway Offshore Treatment

For a payment gateway operator, the IRD examines where the essential activities that generate the processing fees take place. These may include marketing to merchants, negotiating contracts, managing merchant relationships, handling disputes, and maintaining the payment infrastructure. If these core operations are performed in Hong Kong, the profits are chargeable to profits tax regardless of where the server sits. DIPN 39 paragraph 16 records that in ING Baring Securities (Hong Kong) Ltd v CIR (2007) 10 HKCFAR 417, the focus is on the effective causes of the profit, as distinct from activities antecedent or incidental to the transaction. The effective causes of a payment processor's profit are the activities that bring the merchant on board and enable the transaction, not the automated processing itself.

Core Operations and Effective Causes

The IRD distinguishes between core operations that produce profits and activities that are merely preparatory or incidental. For a payment processor, core operations include:

• Soliciting and contracting with merchants
• Setting transaction fees and terms
• Managing settlement and reconciliation
• Handling chargebacks and disputes
• Maintaining compliance with payment card industry standards

Automated operations such as authorising transactions, routing payment data, and updating ledgers are considered incidental to these core activities. DIPN 39 paragraph 18 clarifies that an agent, for this purpose, can be a natural or legal person but "does not include software or a server, no matter how advanced it is." An internet service provider merely operating a server under a website hosting arrangement is not an agent either. A payment processor cannot argue that its server is an agent performing the profit-generating activities.

The High Bar for Offshore Treatment

DIPN 39 paragraph 15 quotes CIR v HK-TVB International Limited [1992] 2 AC 397, where Lord Jauncey said it "can only be in rare cases that a taxpayer with a principal place of business in Hong Kong can earn profits which are not chargeable to profits tax under section 14." This sets a high bar for any offshore claim. A payment processor with its management, sales team, and operational staff in Hong Kong will find it difficult to argue that its processing profits are sourced offshore. The locality of profits is determined by where the profit-earning operations take place, not where the technology sits.

Contrast with Trading Profits

For trading profits, the locality is generally the place where the contracts for purchase and sale are effected. Trading profits are wholly taxable or wholly non-taxable; apportionment is not appropriate. Payment processing profits are different. The IRD does not apportion processing profits between onshore and offshore activities in the same way it might for a mixed manufacturing and trading operation. If a payment processor has genuinely separate operations, a merchant acquisition team in Hong Kong and a separate processing centre in another jurisdiction, the facts of each case determine the outcome. The IRD examines the effective causes of the profit, not the mechanical steps.

Non-Resident Payment Processors

Section 50AAK(1) treats a non-Hong Kong resident person as carrying on a trade, profession or business in Hong Kong if it has a permanent establishment here. The absence of a permanent establishment does not by itself mean the person is not carrying on business in Hong Kong. A non-resident payment processor that solicits merchants in Hong Kong, negotiates contracts here, or provides ongoing support to Hong Kong merchants may be carrying on business in Hong Kong and chargeable to profits tax on its processing profits. The IRD may issue a BIR54 to a non-resident person to file a profits tax return.

Practical Checklist of Factors the IRD Considers

When assessing whether a payment processor's profits are sourced in Hong Kong, the IRD considers:

• Where the contracts with merchants are negotiated and signed
• Where merchant relationships are managed
• Where the sales and marketing team is based
• Where technical support and dispute resolution are handled
• Where management decisions about pricing and strategy are made
• Where the payment infrastructure is maintained and monitored
• Where the server is located (relevant but not determinative)

A payment processor that conducts all of these activities in Hong Kong should expect its processing profits to be chargeable to profits tax at the two-tiered rates: 8.25% on the first HK$2,000,000 of assessable profits and 16.5% on the remainder for corporations. Filing is through the Business Tax Portal using Form BIR51 for corporations, with supplementary forms as required.

DIPNs and Their Legal Status

DIPNs are not legally binding. They state the Department's interpretation, and rights of objection and appeal are unaffected by them. A payment processor that disagrees with the IRD's assessment may object and, if necessary, appeal to the Board of Review or the courts. The consistent judicial approach, as shown in ING Baring and HK-TVB, supports the IRD's focus on effective causes and core operations rather than server location. Any offshore claim should be supported by clear evidence that the profit-generating activities occur outside Hong Kong, not merely that the server is located elsewhere.
