Executive Summary
General Requirements
- The Special Taxation Measures Law (STML) Article 66-4 mandates the arm’s length principle for all transactions with foreign related persons.
- An associated relationship is defined by a 50% or greater direct or indirect ownership interest, or the existence of factual control over business decisions.
- While the framework aligns closely with OECD Guidelines, domestic law and administrative circulars take priority as the governing authority.
- Compliance obligations are strictly limited to cross-border transactions, with no formal documentation requirements for domestic intra-group dealings.
Documentation Requirements
- Taxpayers must adhere to a three-tiered documentation structure including a Master File, a Local File, and a Country-by-Country (CbC) Report.
- A mandatory disclosure form, Schedule 17-4, must be attached to the annual corporate income tax return for all taxpayers engaged in foreign related-party transactions.
- The Local File must include segmented profit and loss information for both the tested party and the foreign counterparty to the transaction.
- Documentation is considered contemporaneous only if prepared by the deadline for filing the corporate income tax return.
Results of Non-Compliance
- Failure to provide a requested Local File within the designated timeframe empowers tax authorities to apply presumptive taxation based on simplified methods.
- Non-compliance with documentation requests results in the reversal of the burden of proof, shifting the responsibility to the taxpayer to disprove the authority’s assessment.
- Administrative fines of up to JPY 300,000 are imposed for the failure to submit or the late submission of a Master File or CbC Report.
- The statute of limitations for transfer pricing assessments is seven years for business years commencing on or after April 1, 2020.
Country Specific Information
- Tax authorities maintain a strong preference for local Japanese comparables and often reject regional or global sets due to market differences.
- If a taxpayer fails to provide requested documentation, authorities are explicitly authorized to use secret comparables to determine arm’s length prices.
- Taxpayers must navigate dual interest restriction rules: a 3:1 debt-to-equity thin capitalization limit and a 20% EBITDA-based earnings stripping rule.
- While benchmarking searches should ideally be updated annually, authorities may accept a three-year renewal cycle provided business conditions remain stable.
