Main content

Avoid tax assessment due to affiliate transactions This is a costly lesson for a multinational corporation in Vietnam when an audit discovered an unusual profit level in transactions with a parent company abroad. The tax authority then proceeded to assess taxes, leading to a large amount of arrears and disrupting investment expansion plans. This case shows that corporations with related-party transactions need to develop a strategy to comply with OECD standards and Decree 132/2020/ND-CP from the beginning to ensure stable and sustainable operations.

Concept of tax avoidance due to related party transactions 

Avoid tax assessment due to affiliate transactions is a set of measures and strategies that help businesses minimize the risk of tax authorities redetermining tax obligations for transactions between related parties. This includes building complete records, applying OECD standard valuation methods, strict internal controls and timely updating of legal regulations. Proper implementation will help businesses limit tax arrears, administrative penalties and maintain credibility with investors.

Why do businesses need to avoid taxes due to related-party transactions? 

Enterprises today face increasing compliance pressure from tax authorities, especially in relation to related party transactions between companies in the same group or between parent companies and subsidiaries. If the Arm's Length Principle is not followed, tax authorities have the right to impose taxes, leading to enterprises having to pay additional corporate income tax (CIT), administrative fines and late payment interest.

When implemented synchronously, enterprises not only comply with the law but also strengthen their tax risk management strategy.

After understanding the legal framework, businesses can be proactive in avoiding tax imposition due to related-party transactions. It can be seen the importance of fully complying with documents, applying the correct valuation method and data transparency. To better understand the consequences of non-compliance, let's review some actual violations detected by tax authorities with MAN - Master Accountant Network, thereby drawing valuable lessons for tax risk management.

Cases of not proactively avoiding tax assessment due to related party transactions

Below is a summary of cases where businesses may be subject to tax assessment by tax authorities related to related party transactions.

Board: Summary of tax cases related to related transactions.

CaseDetailed explanationLegal basis
The transfer price does not follow the principle of independent market price.If an enterprise determines that the transaction price between related parties is lower or higher than the market price in order to reduce taxable income, the tax authority has the right to adjust and collect corporate income tax and value added tax (VAT).Law on Tax Administration 2019 Decree 132/2020/ND-CP; 

OECD Guidelines on Related Party Transactions

Missing or incorrect documents proving related transactionsEnterprises that do not prepare or do not fully prepare documents proving the value of related-party transactions (for example: Comparative price analysis report, valuation method) will be taxed according to the estimated value of the tax authority.Article 13, Decree 132/2020/ND-CP
Affiliate transactions do not conform to standard profit marginsIf the actual profit of an enterprise differs too much from the standard profit in the industry (e.g., NPM, ROA, TNMM), the tax authority may apply the method of determination based on comparison with independent companies.OECD Guidelines
Related transactions involving intangible assets not properly valuedIntangible assets such as trademarks, patents, software, and technological know-how that are not properly valued or under-declared will be subject to tax assessment based on the value determined by the tax authority.Article 16 of Decree 132/2020/ND-CP
Transfer of losses or transfer pricing between associated companiesActs of transferring profits between parent companies and subsidiaries and affiliated companies abroad to optimize taxes may lead to tax assessment when discovered by tax authorities.Tax Administration Law, OECD Guidelines on Transfer Pricing.
Conducting “non-substantive” transactionsIf a related party transaction is solely for tax avoidance purposes and has no real economic or commercial basis, the tax authority may invalidate the transaction and impose tax.Decree 132/2020/ND-CP

From the above cases, it can be seen that being taxed due to related-party transactions not only entails the risk of collecting corporate income tax, administrative fines and late payment fees. Therefore, avoiding tax imposed due to related-party transactions is a decisive factor in helping businesses ensure compliance with the law and maintain competitive advantages in the market.

For example: Company G rents a factory from its parent company for 50,000,000/month, but the equivalent rental price on the market is 80,000,000/month. 

Low rental prices reduce tax liability compared to market prices. Company G does not prepare rental price comparison records and cannot prove that there are any special favorable conditions to rent at low prices. 

Consequence:

  • The rental price difference is 30,000,000/month, so the total cost for 1 year is 360,000,000, which is re-determined as an expense exceeding the allowable limit, leading to a reduction in valid expenses, thereby increasing taxable profit.
  • Tax arrears of 72,000,000/year and additional penalties for violations.

Measures to avoid being taxed due to related party transactions 

To avoid tax imposition due to related-party transactions, enterprises not only need to be aware of compliance but also need to deploy a comprehensive system of solutions, from document preparation, choosing valuation methods, to internal control and data transparency. These measures not only help minimize legal and financial risks, but also strengthen the enterprise's reputation in the eyes of investors and management agencies. The table below will list the key steps that enterprises need to pay attention to.
