LEGAL UPDATES | Decree 255/2026/ND-CP: Significant Changes in Tax Administration for Related Party Transactions
On July 1, 2026, the Government officially implemented Decree No. 255/2026/ND-CP on tax administration for enterprises with related party transactions. This Decree replaces Decree 132/2020/ND-CP and Decree 20/2025/ND-CP, while continuing to refine the legal framework for anti-transfer pricing in line with OECD international standards.
Although maintaining the basic structure of current regulations, Decree 255 adds many important contents related to comparative analysis data sources, exemption from preparing Transfer Pricing Documentation (Local File), Country-by-Country Report (CbCR), and information exchange mechanisms between Vietnamese tax authorities and foreign tax authorities.
These changes will directly affect enterprises with related party transactions, especially multinational corporations and FDI enterprises operating in Vietnam.
1. Clarifying Requirements for Transfer Pricing Documentation
Decree 255 continues to affirm the principle that enterprises must prepare Transfer Pricing Documentation no later than the time of submitting corporate income tax finalization dossiers and retain it for submission when requested by tax authorities.
In addition, the Decree supplements and clarifies several important concepts such as:
- Ultimate Parent Entity;
- application of international tax treaties;
- legal basis related to the Law on Tax Administration.
Although these are mainly clarifications of existing regulations, the more specific provisions indicate that the regulatory agency has higher expectations for timely and fully documented preparation of dossiers.
OPLAW Insight
In practice, during tax audits, many enterprises only begin preparing Transfer Pricing Documentation after receiving an inspection decision. This approach carries significant risks because the law requires the documentation to be completed at the time of tax finalization, not when tax authorities request clarification.
2. First-time Regulation of Priority Order for Comparative Analysis Data Sources
One of the notable new points is that Decree 255 clearly specifies the priority order when selecting comparative data for determining related party transaction prices.
Accordingly, enterprises should prioritize using:
Firstly, public or official data sources, including:
- data from stock exchanges;
- commodity exchanges;
- national databases;
- other officially published data sources.
Secondly, commercial databases.
Thirdly, data managed by tax authorities.
Significance for Enterprises
The clear regulation of the priority order helps enterprises have a basis for selecting transparent, objective, and more defensible data sources when explaining to tax authorities during audits or inspections.
At the same time, enterprises also need to review their current benchmarking methods to ensure compliance with the new guidelines.
3. Loosening Conditions for Exemption from Transfer Pricing Documentation
Decree 255 adjusts the mechanism for exemption from preparing Transfer Pricing Documentation in a way that is more favorable to enterprises.
Two notable changes include:
- raising the revenue threshold for exemption from documentation from under VND 200 billion to under VND 500 billion in some cases;
- abolishing the qualitative criterion of "simple functions" when considering conditions for documentation exemption.
Significance
Removing qualitative criteria will help enterprises easily determine whether they are eligible for documentation exemption, while limiting different interpretations during application.
However, enterprises need to note that exemption from Transfer Pricing Documentation does not mean exemption from the obligation to declare or prove the arm's length nature of related party transactions when requested by tax authorities.
4. Important Changes to Country-by-Country Report (CbCR)
Decree 255 significantly updates the regulations on Country-by-Country Report (CbCR) to align with international standards.
Some notable points include:
Change in Revenue Threshold
Instead of using the threshold of VND 18,000 billion as before, the Decree now applies the international threshold of EUR 750 million in consolidated revenue for the group.
This conversion helps synchronize with the OECD's Base Erosion and Profit Shifting (BEPS) Action Plan.
Submission Deadline
If an enterprise in Vietnam has the obligation to submit a CbCR:
- The report must be prepared in XML format;
- the submission deadline is 12 months from the end of the ultimate parent entity's fiscal year.
In addition, the designated enterprise must also submit Form 01/TB-BCLN to notify the entity responsible for submitting the CbCR.
One-time Notification Mechanism
The Decree allows enterprises to notify only once.
If there are changes in information, they must be updated within 90 days from the date the change occurs.
This regulation significantly reduces administrative procedures for multinational corporations.
5. Clarifying When Enterprises in Vietnam Must Submit CbCR
Compared to Decree 132, Decree 255 specifies more clearly the cases where enterprises in Vietnam must or must not submit Country-by-Country Reports.
Enterprises are not required to submit in Vietnam if:
- the ultimate parent entity or designated entity has submitted CbCR abroad;
- that country has an automatic information exchange mechanism with Vietnam and meets the prescribed conditions.
Conversely, enterprises may incur the obligation to submit in Vietnam if:
- the parent company's country does not exchange information with Vietnam;
- the information exchange mechanism is not operating effectively;
- international standards for data confidentiality and use are not met.
This is a very important content for multinational corporations because the obligation to submit CbCR in Vietnam depends not only on domestic regulations but also on the status of information exchange between Vietnam and the country where the parent company is located.
6. Greater Transparency in International Information Exchange Mechanisms
A notable new point is that the Decree requires Vietnamese tax authorities to publicly disclose on their electronic portal contents related to the exchange of CbCR with other countries.
Information to be disclosed includes:
- a list of countries and territories with information exchange mechanisms with Vietnam;
- cases where the exchange mechanism is not operating effectively;
- the status of compliance with international standards for data confidentiality and use.
This helps businesses proactively monitor to accurately determine CbCR obligations in Vietnam.
What should businesses prepare?
To ensure compliance with Decree 255/2026/ND-CP, businesses should:
- review all related-party transactions arising during the fiscal year;
- prepare the Transfer Pricing Documentation Package by the tax finalization deadline;
- re-evaluate the exemption conditions for documentation based on the new revenue thresholds;
- check the group's obligation to prepare and submit the CbCR;
- regularly monitor tax authorities' announcements regarding international information exchange mechanisms;
- enhance coordination between finance, tax departments, and the parent company to ensure data consistency and compliance deadlines.
OPLAW Insight
Decree 255/2026/ND-CP does not introduce groundbreaking changes in transfer pricing policy, but it clearly demonstrates a trend towards standardization and increased transparency in tax administration, while aligning with international practices in anti-transfer pricing. The new regulations on comparable data sources, documentation exemption conditions, and Country-by-Country Reports will require businesses to be more proactive in preparing documents, managing data, and coordinating with the parent group.
For FDI enterprises and multinational corporations, compliance is no longer limited to declaring related-party transactions but requires building a comprehensive tax management system, ensuring documents are prepared on time, data is verifiable, and ready for explanation when tax authorities conduct inspections or audits. This will help minimize tax risks, protect transfer pricing policies, and enhance compliance in an increasingly stringent tax management environment.
