Transfer pricing record-keeping obligations for Hong Kong companies.

Hong Kong companies that enter into related party transactions, whether with an overseas parent, a subsidiary or another affiliated entity, may need to prepare and retain transfer pricing documentation under the Inland Revenue Ordinance (IRO). While the rules require related party transactions to be priced on an arm’s length basis, they also impose specific record-keeping obligations through the Master File and Local File requirements.

Whether a company needs to prepare these documents depends on its size and the value of its controlled transactions. This guide explains when the documentation requirements apply, how the exemption thresholds work, what supporting records businesses should keep, the nine-month preparation deadline and what to expect if the IRD requests the documentation.

When transfer pricing rules apply to Hong Kong companies

Transfer pricing rules apply wherever a Hong Kong entity carries out transactions with an associated person, commonly described as a related party. This typically covers a Hong Kong subsidiary transacting with its overseas parent, a Hong Kong holding company dealing with its subsidiaries or transactions between fellow subsidiaries under common ownership. The rules also extend to a non-resident entity’s permanent establishment operating in Hong Kong.

The underlying obligation is to price these transactions on an arm’s length basis, meaning on terms that independent parties would have agreed. This applies across several transaction types:

• Sale and purchase of goods, including trading stock and finished products
• Provision of services, including management fees and shared service charges
• Loans and other financing arrangements between group entities
• Licensing or transfer of intangibles, such as trademarks and know-how

Master File and Local File thresholds

Not every Hong Kong entity with related party transactions needs to prepare a Master File and Local File. Two separate exemption tests apply, and an entity only carries the documentation obligation if it fails both.

The first test looks at the size of the business. An entity that satisfies any two of the following three conditions for the accounting period is exempt, regardless of its transaction volume:

• Total revenue for the accounting period does not exceed HKD 400 million
• Total value of assets at the end of the accounting period does not exceed HKD 300 million
• Average number of employees during the accounting period does not exceed 100

The second test looks at the value of controlled transactions, assessed separately by category. If an entity fails the business size exemption, it still does not need to cover a particular category in its Local File where the total amount for that category stays within the following thresholds:

Each category is tested on its own, without offsetting one against another, and it is the arm’s length amount of the transaction that counts towards the threshold, as set out in the IRD’s transfer pricing documentation guidance. If every category of an entity’s controlled transactions stays within these thresholds, the entity does not need to prepare a Master File or Local File at all. Where only one category exceeds its threshold, the Local File only needs to cover that category, and the others can be left out.

However, once the obligation is triggered under any category, a Master File is also required, as the requirement is assessed at the entity level rather than on a category-by-category basis.

Understanding the Master File and Local File

The Master File and Local File serve different purposes, and understanding the distinction helps a company work out where its real preparation effort goes.

The Master File

The Master File gives a group-level overview: organisational structure, the group’s businesses, its intangibles, intercompany financial activities and its overall financial and tax position. Many Hong Kong entities that are part of a larger group can rely substantially on a Master File prepared centrally by the parent company, since the IRD generally accepts a centrally prepared file as appropriate, provided it contains the information prescribed under Schedule 17I to the IRO. Where the parent’s file is missing required categories of information, the Hong Kong entity may be asked to supply supplementary details to fill the gap.

The Local File

The Local File is entity-specific. It sets out the material controlled transactions the Hong Kong entity has actually carried out, the associated entities involved, the amounts concerned and the transfer pricing analysis supporting the pricing applied. For most Hong Kong SMEs within a multinational group, the Local File is where the bulk of the practical preparation work sits.

Supporting documentation for the Local File

A company’s books and source documents typically capture the following for each material transaction:

• Intercompany invoices that reflect the pricing basis actually applied
• Loan or financing agreements, including interest rate basis, tenor and any guarantee terms
• Service agreements that set out the scope of services provided and the cost allocation methodology used
• Documentation of the transfer pricing method applied, including any benchmarking analysis behind the pricing or margin

Certain elements of the Local File, such as benchmarking studies and comparable company data, can be rolled forward for up to three years where the conditions of the underlying transactions remain consistent. This does not remove the need to prepare a Local File in each of those years. It only means some of the analytical content within it can carry over rather than being rebuilt from scratch annually.

Preparation deadlines and IRD reviews of related party transactions

Meeting the preparation deadline alone is not enough. Companies also need to understand how the IRD reviews transfer pricing documentation and the consequences of failing to meet its requirements.

The nine-month preparation deadline

Under section 58C(2)(a) of the IRO, a Hong Kong entity prepares its Master File and Local File no later than nine months after the end of its accounting period. Separately, the entity declares in its Profits Tax Return and supplementary Form S2 whether it has related party transactions and whether the Master File and Local File obligation applies.

What “available on request” means in practice

The files are not submitted automatically alongside the tax return. Instead, the IRD conducts desk-based reviews, typically within six months of the return being filed. Entities that declared the obligation, or whose business size exceeds the exemption thresholds, are the ones most likely to be selected.

A selected entity receives an enquiry letter and completes Form IR1475, which summarises the information held in the Master File and Local File. Form IR1475 also captures the entity’s exemption position, including whether a transaction amount stays within the applicable threshold. Where the entity did not declare a documentation obligation in its supplementary Form S2, the IRD can ask it to explain how the relevant exemption conditions are met. That explanation forms part of the IR1475 process and does not amount to a separate written statement for every exempt transaction.

Consequences of incomplete or missing documentation

Proper documentation is what allows a company to demonstrate that it made reasonable efforts to apply the arm’s length principle. This matters even where an adjustment is ultimately made: an entity that can show reasonable effort is not liable for the additional tax that would otherwise apply under section 82A.

Where a desk-based review finds that a required Master File or Local File was not prepared within the nine-month window, the Assessor can pursue prosecution under section 80(2Q) of the IRO. This carries a fine of up to HKD 50,000 on conviction, and a further fine of up to HKD 100,000 if a subsequent court order to prepare the files is not followed. Losing the reasonable-efforts protection against additional tax adjustments is the more significant risk in practice, since it places the burden back on the company to justify its pricing after the fact rather than in advance.

Conclusion

Transfer pricing documentation in Hong Kong is a standing record-keeping obligation rather than a one-off exercise triggered by an audit. Whether a company prepares a Master File and Local File comes down to two exemption tests: one based on business size and one based on the value of related party transactions by category. The underlying records capture enough detail on pricing, agreements and methodology to support an arm’s length position if the IRD asks. Meeting the nine-month preparation deadline and keeping the files current each year puts a company in a considerably stronger position than trying to reconstruct that evidence after a review has already started.
