What the transfer pricing file consists of
Where a taxpayer has related-party transactions, it is responsible for retaining and providing a transfer pricing file comprising information, documents, data and records:

| Component | Legal basis |
|---|---|
| Information on related-party relationships and transactions in the prescribed form | Appendix I, Decree 132/2020/ND-CP dated 5 November 2020 |
| Local file — transfer pricing information, policies and methods, prepared and held at the taxpayer’s offices | Appendix II, Decree 132/2020/ND-CP |
| Master file — the multinational group’s business activities, global transfer pricing policies and methods, and policies on income allocation and the decentralisation of functions along the group’s value chain | Appendix III, Decree 132/2020/ND-CP |
| Country-by-Country Report (CbCR) of the ultimate parent company | Clause 5 and Appendix IV, Decree 132/2020/ND-CP |
Decree 132/2020/ND-CP is cited as at the date of drafting. For any specific tax period, the source decree and any amendments in force at that time must be verified.
Why companies must prepare the file
The tax authorities are empowered to set price levels, profit margins or profit-split ratios, and to assess taxable income or corporate income tax payable for any taxpayer that fails to comply with transfer pricing declaration or determination requirements, or that fails to provide — or provides incompletely — the data and information required to determine related-party transaction prices.
For a company with related-party transactions, preparing and maintaining the transfer pricing file is therefore compulsory, not optional.
