Transfer pricing basics for SMEs

The arm's length principle, when documentation is required, the exemptions for smaller businesses, and practical steps for related-party transactions.

By DBMS GlobalLast reviewed: 18 October 2026

The answer first

When a Hong Kong company trades with a related company, such as a parent, subsidiary or sister company, the price must reflect what independent parties would agree: the arm's length principle. Hong Kong has a statutory transfer pricing regime, with documentation requirements that apply to larger groups and larger transactions.

The arm's length principle applies regardless of size, and the Inland Revenue Department can adjust profits that do not meet it. Where documentation is required, it must be prepared within 9 months after the end of the accounting period and kept for at least 7 years.

Who must prepare documentation

ExemptionThreshold
Business sizeExempt if the entity meets any two of: total revenue not more than HK$400 million; total assets not more than HK$300 million; not more than 100 employees
Transfers of property (other than financial assets and intangibles)Below HK$220 million
Transfers of financial assetsBelow HK$110 million
Transfers of intangiblesBelow HK$110 million
Other transactions (for example, services, royalties)Below HK$44 million

Large groups with consolidated revenue at or above the threshold must also consider country-by-country reporting.

Common related-party transactions

  • Sales and purchases of goods between group companies.
  • Management, IT, marketing or other service charges.
  • Loans and guarantees between companies.
  • Royalties for brands, technology or other intellectual property.
  • Cost-sharing arrangements.
Key takeawayEven when documentation is not required, keep a short written explanation of how each related-party price was set. It answers most questions from auditors and the Inland Revenue Department.

Practical steps

  • List all related-party transactions and their annual values.
  • Check whether the business-size or transaction exemptions apply.
  • Put written intercompany agreements in place.
  • Document how prices are set and benchmarked.
  • Review annually and when the business changes.
Penalty exposureFailure to prepare required documentation can lead to prosecution and fines. Transfer pricing adjustments can result in additional tax and penalties. Specialist advice is needed for documentation and benchmarking.
