Transfer Pricing Vietnam vs China: Comparison and BEPS

Transfer pricing Vietnam vs China: a full comparison and the BEPS impact

Transfer pricing is the area Vietnam–China businesses "touch" the most and understand the least. A group with a parent in China, a factory in Vietnam, selling semi-finished goods back and forth, paying management service fees and royalties — every intra-group transaction is a related-party transaction subject to the arm's length principle, at both ends, Vietnam and China.

This guide to transfer pricing Vietnam China BEPS comparison compares the two countries' transfer pricing frameworks across 7 axes, in a context where both have domesticated the OECD/G20 BEPS standards.

1. Background: BEPS and how the game changed

BEPS (Base Erosion and Profit Shifting) is the OECD/G20 action plan against multinationals shifting profits to low-tax jurisdictions. Its output is the global standard 3-tier documentation:

1. Master File: the group's overall picture — organizational structure, value chain, intangibles, intra-group financing policy;
2. Local File: the details of the company's related-party transactions in each country — functional analysis, pricing method, comparables;
3. CbCR (Country-by-Country Report): revenue, pre-tax profit, tax paid and headcount allocated by each country where the group operates.

Both Vietnam and China have written these 3 tiers into domestic law — but implementation, thresholds and enforcement intensity differ in important ways, analyzed in detail below.

2. Comparison across 7 axes

Axis 1 — Foundational legal framework

Vietnam: Decree 132/2020/ND-CP (effective 20/12/2020, applicable from the 2020 tax year) is the central instrument on tax administration for enterprises with related-party transactions, within the framework of the Law on Tax Administration 2025 (108/2025/QH15, effective 01/7/2026, replacing the Law on Tax Administration 2019) and its guiding Circular 89/2026/TT-BTC (effective 01/7/2026). Decree 132 replaced Decree 20/2017/ND-CP, tightening documentation and declaration duties.

China: Bulletin 42 of the State Taxation Administration (2016–2017, replacing earlier contemporaneous documentation rules) is the central instrument, alongside Bulletin 64 on APAs and CbCR instruments. China's system characteristically uses detailed, frequently updated bulletins.

Comment: Vietnam uses a "one decree covers all" model; China uses a "multiple topical bulletins" model. Businesses operating in both countries must track two systems with different update rhythms.

Axis 2 — Scope of related-party transactions

Both countries define related-party relationships on ownership/capital ratios and control/management rights — broadly aligned with OECD standards. Typical transactions in the Vietnam–China chain all fall within scope:

• goods trading between the Chinese parent and the Vietnamese subsidiary (materials, finished goods, machinery);
• management service and technical support fees from the parent;
• royalties and technology transfer;
• intra-group loans and financial guarantees.

Practical difference: Chinese tax authorities pay special attention to outbound payments of service fees and royalties — the benefit test is applied very strictly. Vietnam also controls these but its traditional audit focus remains the profit margins of manufacturing FDI enterprises.

Axis 3 — Arm's length pricing methods

Both countries accept the OECD-standard methods:

• Comparable Uncontrolled Price (CUP);
• Resale Price Method (RPM);
• Cost Plus;
• Profit Split;
• Transactional Net Margin Method (TNMM).

Difference in priority: Vietnam (Decree 132) prescribes an order of priority for applying methods; China allows the "most appropriate method" with full reasoning. In practice: for contract manufacturing plants in Vietnam, TNMM with an operating margin indicator is the most common method in both countries.

Axis 4 — Documentation duties (BEPS 3-tier)

Vietnam (Decree 132):

• related-party transaction declaration form (attached to the CIT finalization return);
• Local File;
• Master File;
• Country-by-country report (CbCR) — where applicable.

Documentation must be prepared before the annual tax finalization filing deadline and retained for presentation on tax authority request.

China (Bulletin 42):

• contemporaneous documentation comprising Master File, Local File and Special File (for specific transactions such as intra-group services and cost sharing);
• CbCR;
• annual related-party transaction reporting forms.

Notable difference: China adds a Special File for specific transactions and a detailed benefit test for intra-group service fees — businesses must prove the service delivers real economic benefit, not shareholder activity or duplication.

Axis 5 — Thresholds and exemptions

Both countries exempt small businesses or low-value transactions from documentation — but the specific thresholds differ and may have been adjusted. General principles:

• businesses with related-party transactions below set thresholds are exempt from the Local File (but must still declare);
• CbCR applies only to multinational groups with consolidated global revenue above a high threshold (the BEPS standard: EUR 750 million).

Recommendation: do not "guess" thresholds from this article — check the current instruments, as thresholds are the most frequently amended content.

Axis 6 — APA and MAP mechanisms

APA (Advance Pricing Agreement): both Vietnam and China operate unilateral, bilateral and multilateral APA regimes. An APA is the strongest "shield": the business and the tax authority agree in advance on the pricing method for a period (typically 3–5 years), eliminating reassessment risk.

MAP (Mutual Agreement Procedure): where double taxation results from a transfer pricing adjustment (e.g. Vietnam increases the subsidiary's taxable profit while China does not correspondingly reduce the parent's), the business may request the two tax authorities to negotiate via MAP under the Vietnam–China tax treaty.

Practice: a Vietnam–China bilateral APA takes time (typically 2–3 years of negotiation) but is the structural fix for large, stable value chains. Start early — don't wait for an audit to think about APAs.

Axis 7 — Penalties and audit trends

Vietnam: tax reassessment where the arm's length price cannot be demonstrated; administrative tax penalties; late-payment interest. Trend: Vietnamese tax authorities increasingly use benchmarking data and focus on FDI enterprises with persistent losses and dealings with "tax havens".

China: similar investigation, reassessment and recovery powers; China additionally runs big-data-based risk management — automated analysis of CbCR and related-party returns to select audit targets. Trend: tightening on outbound payments (service fees, royalties paid abroad) and structures showing profit-shifting signs.

4. Recommendations for Vietnam–China businesses

1. One consistent transfer pricing policy for the whole chain: don't let the parent price on Chinese logic while the Vietnamese subsidiary declares on different logic — contradictions between the two dossiers are "easy prey" for both tax authorities;
2. Prepare all 3 tiers in both countries, on time — documentation is the first line of defence in an audit;
3. Benefit-test every service/royalty fee paid to China: keep contracts, work reports, evidence of benefit;
4. Monitor the Vietnamese subsidiary's margins against independent comparables — persistent losses while the group profits is a red flag;
5. Consider a bilateral APA for large, stable value chains — time-consuming but structurally eliminates risk;
6. Prepare a MAP scenario where one-sided adjustments threaten double taxation.

5. The three-tier TP documentation: practice in Vietnam

Decree 132/2020/ND-CP (still the central instrument as of this writing, 28/9/2026, applied within the framework of the Law on Tax Administration 2025 (108/2025/QH15)) requires the BEPS three-tier documentation:

Tier 1 — Master File: the group big picture — organizational structure, value chain, intangibles, internal financing policy. Prepared by the parent; the Vietnamese subsidiary keeps a copy;

Tier 2 — Local File: the heart of Vietnamese compliance — see transfer pricing in Vietnam: the legal framework — detailed related-party transactions of the Vietnamese company, functional–asset–risk (FAR) analysis, transfer-pricing method selection, and benchmarking data. This is the first thing tax inspectors read;

Tier 3 — Country-by-Country Report: only for multinational groups meeting the consolidated-revenue threshold — revenue, profit and tax paid by jurisdiction.

Deadline: the related-party pricing documentation must be prepared before the annual CIT finalization filing and kept at the company for presentation on request — see the annual transfer pricing compliance checklist. Not "make it when inspected" — backdated files are detectable from document trails and destroy the credibility of the whole argument.

Practical point: many Vietnam–China FDI firms prepare a thin English Local File hastily translated — while inspectors read Vietnamese. Keep a full Vietnamese version with figures reconciled to audited financial statements.

6. TP audits: red flags and how to respond

Both countries' tax authorities use risk analysis to select audit targets — as shown by the case study on the interest expense cap in transfer pricing. Red flags:

• Persistent losses or abnormally low margins while the group is profitable — the classic flag in both Vietnam and China;
• Transactions with affiliates in tax havens or abnormally low-tax jurisdictions;
• Service fees and royalties paid to the parent spiking without commensurate benefit;
• Restructurings moving intangibles or functions out of Vietnam/China.

When the audit decision arrives:

1. Don't panic, don't "fix" documents — every sign of alteration gets noted;
2. Assemble the team immediately: chief accountant, tax advisor, lawyer;
3. Re-check the full TP file for consistency across Local File, financial statements and tax returns;
4. Prepare explanations for each major transaction — auditors usually hit 2–3 key transactions, not everything.

Negotiation and adjustment: if the authority re-prices, the company may complain and litigate in order. Often, settling at a moderate adjustment beats years of dispute.

7. Vietnam–China APA and MAP: the long-term de-risking path

APA (Advance Pricing Agreement): the company and the tax authority agree in advance on pricing methods for related-party transactions over coming years. Benefit: tax certainty, no audits for covered periods. Cost: long negotiation (often 2–3 years) demanding full transparency.

Bilateral Vietnam–China APA: via the mutual agreement procedure (MAP) under the Vietnam–China double tax treaty. Suits groups with large, regular related-party flows between the two countries — e.g., a Chinese parent selling materials to a Vietnamese subsidiary for processing and re-export.

MAP (Mutual Agreement Procedure): when double-taxed (both countries adjusting the same transaction), the company may ask both tax authorities to negotiate. The last-resort safety valve — but slow, so preventive APA beats remedial MAP.

Practical advice: below certain transaction scales, APA costs may not pay off — focus on complete documentation and consistent pricing policy. For large, regular flows, a bilateral APA is a worthwhile investment.

FAQ

Q: A Chinese parent sells goods to its Vietnamese subsidiary — is transfer pricing documentation required?

A: Yes, at both ends. In Vietnam, related-party transactions fall under Decree 132/2020/ND-CP with duties to declare and prepare related-party transaction pricing documentation. In China, related-party transactions with an overseas subsidiary fall under Bulletin 42 with contemporaneous documentation duties.

Q: What are the BEPS 3-tier documents?

A: They comprise: (1) the Local File — details of the company's related-party transactions in each country; (2) the Master File — the overall picture of the multinational group; (3) the Country-by-Country Report (CbCR) — revenue, profit and tax paid allocated by country.

Q: Do Vietnam and China conclude bilateral APAs?

A: Both Vietnam and China operate advance pricing agreement (APA) regimes, including unilateral and bilateral/multilateral APAs. A Vietnam–China bilateral APA runs through the mutual agreement procedure (MAP) under the two countries' tax treaty.

Q: What is the biggest transfer pricing risk for Vietnam–China FDI businesses?

A: A Vietnamese subsidiary with persistent losses or abnormally low margins while the group is profitable — the classic transfer pricing audit trigger in both Vietnam and China. The fix: a consistent transfer pricing policy, complete documentation, and considering an APA.

Q: My company only transacts with its Chinese parent and revenue is below thresholds — must I prepare TP documentation?

A: The documentation duty depends on having covered related-party transactions, not only on revenue. Decree 132 exempts documentation in some cases (e.g., only transacting with affiliates paying CIT in Vietnam at the same rate). But exemption from documentation isn't exemption from disclosure — related-party information must still be declared with the CIT finalization return. When unsure, consult a tax advisor.

Q: Where do I find benchmarking data for the Vietnamese market?

A: The biggest practical difficulty. Common sources: commercial databases (Orbis, Amadeus…), listed peers' public financials, industry association data. For China, the Chinese tax authority has strong internal databases and often uses data from previously audited companies — prepare independent benchmarks with clear methodology for comparison.

Q: How long does a TP audit usually take?

A: Months to over a year depending on scale and complexity. Audits with a foreign element (information exchange with China's tax authority under the treaty) take longer. Keep a stable coordination contact throughout; mid-process personnel changes seriously disrupt.
