As tax authorities continue to tighten their transfer pricing audits, accurately reporting information on related-party transactions has become a mandatory requirement for many businesses. However, many accountants and business owners still face difficulties in identifying related parties, determining the appropriate reporting methods, or completing the required schedules in accordance with regulations.
The following article provides a comprehensive, easy-to-understand guide to preparing a related-party transaction report that strictly adheres to current regulations, helping businesses minimize errors and avoid the risk of back taxes or tax penalties.
What is a related-party transaction report?
The Related-Party Transaction Report is a set of schedules that disclose information about related-party relationships and transactions between a business and its related parties during the tax period. This report is filed along with the annual corporate income tax return.
The purpose of the filing is to help tax authorities monitor transactions that may involve transfer pricing and ensure compliance with the arm’s-length principle among related parties.
Under current regulations, businesses that engage in related-party transactions must fully disclose information regarding:
- Affiliate relationships;
- Value of related-party transactions;
- Methods for determining transaction prices;
- Profit margin;
- Obligations to report and maintain records for determining the price of related-party transactions.
Which entities are required to file a related-party transaction report?

When preparing a related-party transaction report, a business must first determine whether it is required to file such a report. Generally, a business is required to file a report if it falls under one of the following circumstances:
- Parent-subsidiary relationships;
- Are under the common management or control of an organization or individual;
- There were transactions involving loans, the purchase or sale of goods, and services with related parties;
- There are individuals who hold equity interests in accordance with the statutory ratio;
- We conduct business with overseas companies that are part of the same corporate group.
Common transactions you may encounter:
- Buying and selling raw materials;
- Lending – borrowing;
- Transfer of assets;
- Provide internal services;
- Pay management fees;
- Technology transfer or licensing.
Business accountants need to carefully review the ownership structure and transaction flows to avoid overlooking any reporting obligations.
What does a related-party transaction disclosure form include?
Businesses must prepare all required attachments in accordance with regulations. Below is a summary of the documents businesses need to prepare:
| Documents Required | Content |
| Appendix: Affiliate Information | Disclosure of Related Parties |
| Related Party Transaction Appendix | Report the value and type of transaction |
| Appendix Defining Valuation Methods | Explanation of the Basis for Determining the Transaction Price |
| Transfer pricing determination dossier | Supporting documentation to be provided upon request by the tax authority |
Note: In addition, businesses must retain accounting documents, contracts, comparative analysis materials, and other relevant records to assist with tax audits when necessary.

Common Errors in Preparing Related-Party Transaction Reports

In fact, many businesses have had their tax filings rejected by the tax authorities, resulting in back taxes or penalties. The main reasons are:
- The affiliated party has not been fully identified;
- Failure to report loan transactions;
- Incorrect transaction value;
- No appraisal report was prepared;
- Choosing the wrong comparison method;
- The data does not match the financial statements;
- Late filing of tax returns.
Many businesses today, even though they have filed their tax returns, are still being asked by the tax authorities to provide explanations due to illogical data or the incorrect selection of a pricing method. This is also why an increasing number of businesses are turning to related party transaction advisory services to have their records reviewed, data standardized, and to receive assistance in addressing transfer pricing risks in accordance with Decree 132.
