Advance pricing agreements in Vietnam: when should a business negotiate an APA?
The short answer
An Advance Pricing Agreement (APA) is a written agreement between a business with related-party transactions and the tax authority. It sets out in advance the method and basis for pricing related-party transactions, and the critical assumptions, for a defined period.
APAs take three forms:
unilateral: between the business and the Vietnamese tax authority;
bilateral or multilateral: also involving foreign tax authorities under tax treaties.
Circular No. 95/2026/TT-BTC, effective from 1 July 2026, replaces Circular No. 45/2021/TT-BTC and makes two notable points:
a business may request an APA covering up to 5 consecutive tax years;
a signed APA is effective for up to 3 tax years, from the tax period in which it is signed or the following year.
APAs suit businesses with large, stable related-party transactions recurring over many years, especially where pricing has been, or is likely to be, adjusted or disputed.
What problem does an APA solve?
TP documentation is the business's own justification, prepared after transactions have happened. The tax authority may still disagree in an audit.
An APA reverses the order: the parties agree in advance on the method and pricing basis. During its term, if the business complies with the agreement, the scope for transfer pricing disputes over covered transactions is minimised.
A bilateral APA offers even greater benefit. The tax authorities of both countries agree, so the business avoids double taxation where Vietnam adjusts profits upwards but the parent's country does not make a corresponding downward adjustment.
Pros and cons
Advantages | Disadvantages |
Tax certainty for key related-party transactions during the term | A lengthy process, especially for bilateral and multilateral APAs |
Lower cost and time spent on transfer pricing audits | Significant preparation and negotiation costs |
Bilateral APAs prevent double taxation | Requires detailed disclosure and explanation of the business model to the tax authority |
A foundation for long-term investment planning and intra-group pricing | Annual compliance reporting. Changes in critical assumptions may require revision or termination |
When should an APA be considered?
Related-party transactions are a large share of revenue or costs and are stable over many years (e.g. contract manufacturing, export production for the parent, distribution of group products).
Transfer pricing adjustments have already been made, or there is a long-running dispute with the tax authority.
There is a risk of double taxation with the parent's country, where a tax treaty and mutual agreement procedure exist.
Transactions are complex and comparables are hard to find, such as unique intangibles or integrated supply chains.
A major expansion is planned and tax certainty is needed to decide.
Conversely, an APA is usually unsuitable where related-party transactions are small, the business model is still changing rapidly, or the business is not yet ready in terms of data and documentation.
The APA process: main steps
Pre-filing consultation: preliminary discussions with the tax authority on the scope of transactions, method and documents required. Circular No. 95/2026/TT-BTC places emphasis on this step, which helps avoid unsuccessful applications.
Formal application: covering the scope of transactions, functional analysis, proposed method, comparable data, critical assumptions and the requested period (up to 5 years).
Review and meetings: the tax authority reviews, requests additional information and may visit the business.
Negotiation: for bilateral and multilateral APAs, there is an additional round of negotiation between tax authorities.
Signing: the APA is effective for up to 3 tax years under the rules.
Compliance: submit an annual APA compliance report, and give notice if critical assumptions change.
Under the new rules, unilateral APA applications are handled by units designated by the Tax Department.
Illustrative case
Company DD, a Korean-invested electronics manufacturer, exports its entire output to its parent. Related-party revenue exceeds VND 5,000 billion a year. In two audits, the Vietnamese tax authority adjusted its profit margin upwards. The Korean tax authority did not accept a corresponding downward adjustment, so the group was taxed twice on the same profit.
The group decided to apply for a bilateral APA. The reasons: stable transactions, very large values and a real risk of double taxation. It began with pre-filing consultations with both tax authorities and prepared a detailed functional analysis and comparable data.
Although the process is lengthy, the expected outcome is a profit-margin range accepted by both countries. That outcome is a sufficient foundation for the factory expansion plan.
FAQs
How long does an APA last?
Under Circular No. 95/2026/TT-BTC, a business may request coverage of up to 5 consecutive tax years. However, a signed APA is effective for up to 3 tax years, from the tax period in which it is signed or the following year.
What is the difference between a unilateral and a bilateral APA?
A unilateral APA is agreed only with the Vietnamese tax authority. A bilateral or multilateral APA also involves foreign tax authorities, preventing double taxation, but usually takes longer.
Should small businesses apply for an APA?
Usually not. APAs suit large, stable related-party transactions with a risk of dispute or double taxation.
What about APA applications filed before 1 July 2026 but not yet signed?
They continue to be processed under the new Law on Tax Administration and Circular No. 95/2026/TT-BTC.
Legal basis
Law on Tax Administration No. 108/2025/QH15 (Article 30(3) and Article 31(2)).

Circular No. 95/2026/TT-BTC guiding tax treaties, the mutual agreement procedure (MAP) and APAs.
Decree No. 255/2026/ND-CP on tax administration of related-party transactions.

An APA is an investment in tax certainty. Businesses should weigh benefits against costs carefully before starting. W&A supports businesses with:
APA suitability assessment: analysing current transfer pricing risk and the benefits and costs of a unilateral or bilateral APA.
Preparing pre-filing consultations and APA applications: functional analysis, method, comparable data and critical assumptions.
Support throughout meetings and negotiations with the tax authority.
Annual APA compliance reporting and management of changes in critical assumptions.
Mutual agreement procedures (MAP) where transfer pricing adjustments lead to double taxation.
