Amidst the Vietnamese tax authorities' tightening of inspections of related-party transactions and the Global Minimum Tax Rate (Pillar Two) regulations, many FDI enterprises are facing the risk of being assessed and having tens of billions of dong in back taxes collected due to unsubstantiated or methodologically incorrect transfer pricing documentation. The issue isn't whether the enterprise intentionally engaged in transfer pricing, but rather whether it has sufficient grounds to prove that all transactions adhered to market pricing principles. Without timely preparation, risks related to taxes, late payment penalties, and loss of investment incentives can quickly become a financial and reputational burden. Therefore, seeking FDI transfer pricing tax consulting is becoming a mandatory solution to help businesses proactively control risks and build standard documentation. Decree 132/2020/ND-CP and confidently defend themselves against any tax audit.
Legal concerns for FDI businesses in 2026
Entering 2026, FDI enterprises in Vietnam are facing an extremely stringent legal framework. On one hand, there is the tightening enforcement of Decree 132/2020/ND-CP; on the other hand, the global minimum tax (Pillar Two) has come into stable operation. Many businesses are still struggling with the question: How to explain complex related-party transactions when tax authorities are increasingly sophisticated in applying information technology and artificial intelligence for inspections? The lack of a well-structured FDI transfer pricing tax advisory strategy from the beginning of the fiscal year will leave businesses in a passive position.
Without thorough preparation or a professional and experienced FDI transfer pricing tax consulting firm, businesses can easily fall into the trap of having their taxes assessed unfairly. When documentation is unconvincing or fails to demonstrate the market-based nature of the transaction, the tax authorities have the right to use internal databases to impose a profit margin. This can lead to tax arrears amounting to tens or even hundreds of billions of VND.
Legal Context for Transfer Pricing Tax in Vietnam 2026: Key Updates

To build an effective risk management strategy, businesses need a deep understanding of the ever-changing "rules of the game." The interplay between domestic regulations and international multilateral commitments has created a multi-layered monitoring system. Below are key points in the 2026 legal framework regarding transfer tax that FDI businesses need to pay special attention to in order to ensure compliance.
Effectiveness of Decree 132/2020/ND-CP and its guiding documents
Decree 132/2020/ND-CP remains the guiding principle for regulating related-party transactions in Vietnam. The core point that all FDI transfer pricing tax consulting firms must emphasize is the accurate identification of related parties according to Article 5 of this Decree.
Specifically, businesses need to be aware of the following thresholds:
- Equity relationship: One party directly or indirectly holds at least 25% of the other party's owner's equity.
- Loan-to-loan relationship: One party guarantees or lends capital to the other party on the condition that the loan amount is at least equal to 25% of the owner's equity of the borrower and accounts for over 50% of the total value of the borrower's medium and long-term debts. This is the most common mistake that causes FDI enterprises to "unintentionally" fall into related-party relationships without knowing it, unless they receive timely warnings from FDI transfer pricing tax consulting firms.
- Executive relationship: One business appoints members of the board of directors or holds de facto control over the business decisions of another business.
Impact of the Global Minimum Tax (Pillar Two) in 2026
In 2026, Vietnam officially implemented the Minimum Domestic Tax Rate (MDG) standard. This regulation completely changed the game. Previously, transfer pricing was often used to shift profits from high-tax jurisdictions to low-tax jurisdictions (Vietnam – with its tax incentives). However, with the effective tax rate in Vietnam raised to the minimum level of 15%, profit shifting no longer offered the same tax benefits as before.
At this point, the role of FDI transfer pricing tax consultants is to help businesses review their entire global supply chain, ensuring that profit allocation accurately reflects the value contribution of the entity in Vietnam, avoiding double taxation due to overlaps between domestic law and international rules.
Practical difficulties and barriers that FDI enterprises face.

Complying with tax laws in Vietnam is not simple due to the unique characteristics and rapid changes in policies. An experienced FDI transfer pricing tax consulting firm like MAN – Master Accountant Network will point out the following obstacles for businesses:
Pressure from the 3-tiered Transfer Pricing Documentation system.
According to international practice and domestic law, businesses must prepare:
- Local File: Focuses on transactions within Vietnam. This is where FDI transfer pricing tax consultants must conduct a FAR Analysis (Function – Assets – Risk). If it cannot be demonstrated that the Vietnamese enterprise bears actual risk, the tax authorities may disallow retained earnings.
- Global corporate profile (Master File): Provides an overall view of the corporation's value chain. The difficulty lies in the fact that data from the parent company is often very incomplete or does not match Vietnamese classification standards.
- Country-by-Country Profit Reporting (CbCR): For corporations with revenues exceeding VND 18 trillion (€750 million). The automated exchange of information between national tax authorities makes it easier for Vietnam to detect unusual profit discrepancies.
For many years, Vietnamese tax authorities have maintained close monitoring of FDI enterprises that frequently report losses or have profit margins lower than the industry average. Without support from FDI transfer pricing tax consultants, it is very difficult for businesses to explain that losses are due to market factors, rising raw material costs, or the initial investment phase, rather than transfer pricing.
Regulations on controlling interest costs
This is a "nightmare" for capital-intensive projects. The regulation capping interest expense deductions at 30% EBITDA unfortunately disallows many FDI businesses from deducting these expenses. MAN's FDI transfer pricing tax consultants will help businesses calculate the optimal capital plan (equity and debt) to minimize these losses.

Analyzing methods for determining transfer pricing.
To build a complete and accurate transfer pricing dossier, FDI tax consulting firms must choose the method most appropriate to the business sector in which the enterprise operates. Below are 5 standard methods stipulated in Decree 132/2020/ND-CP:
- The Comparative Independent Transaction Price (CUP) method: Directly compares the price of a product in a related-party transaction with the price of a product in an independent transaction. This method has the highest reliability but requires absolute similarity in product characteristics and contract conditions.
- Resale Price Method: Based on the gross profit margin at which a business purchases from an affiliated party and resells to an independent party. This method is typically applied to businesses with simple trading and distribution operations that do not significantly alter the product's characteristics.
- Cost Plus Method: This method determines the price by adding a reasonable profit margin to the cost of production. FDI transfer pricing consultants often apply this method to businesses engaged in contract manufacturing or providing services within a group.
- The Net Profit Margin Comparison (NPMR) method: This method compares the net profit margin (e.g., profit on revenue or on total costs) of an associated transaction with the margins of comparable independent transactions. This is the most common method in Vietnam due to the ease of finding comparative data compared to other methods.
- Profit Split Method: Determine the total consolidated profit from a related-party transaction, then allocate it to each party based on their contribution of value (assets, functions, risks). FDI transfer pricing consultants recommend this method for complex, highly integrated transactions or when the parties jointly own unique intangible assets for which no comparable data can be found in the market.
To ensure the accuracy of the application documents, your company should consult the relevant resources. hire someone to create a partnership profile. From an experienced unit to always ensure a convincing presentation before inspectors.
Real-world risks: Lessons from transfer pricing tax audits
Let's look at the actual numbers to see why you need FDI transfer pricing tax consulting:
- Case 1: A foreign direct investment (FDI) garment company was ordered to pay back VND 120 billion due to its inability to demonstrate the reasonableness of the management fees paid to its parent company in Singapore. The company independently prepared the documentation without consulting a professional FDI transfer pricing tax advisor, resulting in a completely inaccurate FAR analysis.
- Case 2: An electronics components company was assigned a profit margin of 8% instead of the 3% they declared themselves. This was because the benchmarking data the company used was geographically and functionally inconsistent.
A lack of in-depth understanding of the Laws, Decrees, and Circulars on related-party transactions in Vietnam prevents businesses from formulating strong arguments to defend themselves. FDI transfer pricing consulting services will accompany businesses in building a robust legal framework right from the planning stage.

Frequently Asked Questions about FDI Transfer Pricing Tax Consulting
While not mandatory, this is one of the high-risk indicators that tax authorities often consider during audits. If a business consistently reports losses but continues to expand production, increase revenue, or engage in numerous related-party transactions, there is a high probability of being required to provide explanations under Decree 132/2020/ND-CP.
Exemption may be granted if both revenue is below VND 50 billion and the total value of related-party transactions is below VND 30 billion during the period. However, businesses must still fully declare Appendix I and retain supporting documents when requested by the tax authorities to avoid the risk of tax assessment.
Businesses should conduct benchmarking when there are no comparable independent transactions or when internal data does not accurately reflect the business's functions, assets, and risks. For manufacturing, processing, proprietary distribution, or intra-corporate services, external comparative data is often the most important basis for defending transfer pricing records.
Businesses must demonstrate that the service or intangible asset actually exists, provides economic benefits, and that the fee is consistent with market prices. The documentation should include a contract, payment receipts, documents detailing the work performed, a results report, and a reasonable cost allocation method to avoid disqualification during tax settlement.
Yes. In fact, after an audit, businesses should review their entire operating model, profit margins, and capital structure to avoid repeating mistakes. In many cases, businesses may consider signing an APA agreement with the tax authorities to fix the pricing method for subsequent years.Are FDI companies that incur losses for many consecutive years guaranteed to be subject to transfer pricing audits?
