Vietnam-China Double Taxation Agreement: Practical Guide

A parent company in Shenzhen invests in a factory in Bac Ninh. Each year, the Vietnamese subsidiary pays dividends back to China, pays interest on a loan from the parent, and pays royalties for transferred technology. Every payment faces the same question: will Vietnam tax it at source, will China tax it again, and how can the same dong of income avoid being taxed twice? The answer lies in the double taxation agreement between the two countries — a treaty in force for nearly 30 years yet still frequently misapplied. This guide explains the practical application of the Vietnam-China DTA for businesses.

1. What is a DTA? Who benefits?

A double taxation agreement (DTA) is an international treaty allocating taxing rights between two countries over the same income, serving two goals: preventing taxpayers from being taxed twice, and preventing fiscal evasion. A treaty creates no new tax — it only limits how much each country may tax, or allocates which country may tax each income type.

The Vietnam-China treaty applies to persons who are residents of one or both contracting states (Article 1), covering taxes on income — including personal income tax, corporate income tax and similar taxes later introduced to supplement or replace them (Article 2). In other words: a company tax-resident in China earning Vietnam-source income, or vice versa, may invoke the treaty.

Key point: the treaty only sets rate caps and allocates taxing rights — if Vietnamese domestic law taxes the income at a lower rate or not at all, Vietnamese law applies (a principle carried from Circular 205/2013/TT-BTC into Circular 95/2026/TT-BTC). Applying a DTA is therefore always a two-step exercise: check what the treaty allows, then check what Vietnamese law actually charges.

2. Current legal framework

• Agreement between the Government of Vietnam and the Government of China for the avoidance of double taxation and the prevention of fiscal evasion on income taxes: signed 17/5/1995 in Beijing, effective 18/10/1996. This is the source text setting all rate caps and taxing-right allocations analyzed in this guide.
• Circular 95/2026/TT-BTC (issued 01/7/2026, effective 01/7/2026): guides the implementation of double taxation agreements and fiscal evasion prevention; also guides the mutual agreement procedure (MAP) and the advance pricing agreement (APA) mechanism for enterprises with related-party transactions. It replaces Circulars 205/2013/TT-BTC and 45/2021/TT-BTC.
• Circular 89/2026/TT-BTC (effective 01/7/2026): guides the Tax Administration Law, including procedures for applying tax treaties.
• 2025 Tax Administration Law (108/2025/QH15) (effective 01/7/2026): the general procedural framework for applying international tax agreements in Vietnam.

Important: Circular 205/2013/TT-BTC ceased to be effective on 01/7/2026. Company documents and internal procedures still citing it should be updated to Circular 95/2026/TT-BTC.

This article is based on the original Agreement signed on 17 May 1995 in Beijing and in force since 18 October 1996. Searches of publicly available official sources up to 27 September 2026 identified no amending protocol relevant to the provisions cited here. Filing procedures and timing follow Circular 89/2026/TT-BTC — the full text of which was not verified for this article; confirm with the tax authority or tax counsel for complex transactions.

3. Main income types and rate caps

3.1. Dividends — Article 10: maximum 10%

Dividends paid by a company resident in one contracting state to a resident of the other may be taxed in both states, but if the recipient is the beneficial owner, the source state’s tax must not exceed 10% of the gross dividends (Article 10(2)).

Applied to Vietnam, the second step is needed — what Vietnamese law actually charges:

• Dividends to organizations (a Chinese parent receiving dividends from its Vietnamese subsidiary): current Vietnamese law levies no withholding tax on dividends paid to organizations (Article 4(6) of the Corporate Income Tax Law: dividends from after-tax profits are exempt) — dividends come from after-tax profits. So while the treaty permits up to 10%, in practice no Vietnamese tax arises. This differs markedly from many countries.
• Dividends to individuals (a Chinese-resident individual receiving Vietnamese dividends): subject to personal income tax at 5% on capital investment income. Since 5% is below the treaty’s 10% cap, the 5% domestic rate applies.

Why does the distinction matter? Many Chinese businesses assume “the treaty says 10%” and routinely withhold 10% on dividends to the parent — when nothing should be withheld at all. Conversely, when a Chinese individual receives dividends without the 5% withholding, the Vietnamese payer may face recovery as the withholding agent.

3.2. Interest — Article 11: maximum 10%, government exemption

Interest arising in one contracting state and paid to a resident of the other may be taxed in both states, but if the recipient is the beneficial owner, source-state tax must not exceed 10% of the gross interest (Article 11(2)). Notably, interest paid to the Government of the other contracting state (including state banks and 100% state-owned financial institutions as agreed by both sides) is exempt at source (Article 11(3)).

In Vietnam-China FDI practice, this arises in two common situations: (i) a Vietnamese subsidiary borrowing from its Chinese parent — outbound interest bears foreign contractor tax in Vietnam, with the treaty capping the interest portion at 10%; (ii) loans guaranteed by or sourced from Chinese policy banks — assess whether the Article 11(3) exemption applies, since proving “Government” status demands rigorous documentation.

Note: penalty charges for late payment are not interest under the treaty (Article 11(4)) — penalties follow other rules and do not enjoy the 10% cap.

3.3. Royalties — Article 12: maximum 10%

Royalties arising in one contracting state and paid to a resident of the other, where the recipient is the beneficial owner, are capped at 10% of the gross royalties at source (Article 12(2)). The treaty’s “royalties” definition is broad: copyrights, patents, trademarks, designs, models, plans, secret formulas or processes, the use of industrial-commercial-scientific equipment, and information concerning industrial, commercial or scientific experience.

For Chinese businesses, technology transfer fees, trademark license fees and software usage fees from the parent are typical Article 12 cross-border payments. Practical point: technical service fees involving know-how transfer may be recharacterized by tax authorities as royalties — contracts should clearly separate pure service fees from royalties, as the two face different tax treatment. A detailed analysis of tax on cross-border services clarifies this boundary.

3.4. Business profits and permanent establishment — Articles 5 and 7

Business profits of an enterprise of one contracting state are taxable only there, unless the enterprise carries on business in the other state through a permanent establishment (PE); then the other state may tax only the profits attributable to the PE (Article 7).

The Vietnam-China treaty defines PE broadly (Article 5): places of management, branches, offices, factories, workshops, mines — and two time thresholds Chinese businesses often trip on:

• Construction/installation projects: constitute a PE if lasting more than 6 months.
• Furnishing services (including consultancy) through employees in the other state: constitute a PE if continuing (for the same or a connected project) for more than 6 months within any 12-month period.

In practice: Chinese contractors building, installing machinery or seconding technical experts to Vietnam for extended periods can easily create an inadvertent Vietnamese PE — losing the 10% caps for PE-connected income while all attributable profits become taxable in Vietnam under Article 7. Plan presence duration from the project planning stage, not after the tax authority arrives.

3.5. Gains from alienation of property — Article 13

Article 13 allocates taxing rights by asset type:

• Immovable property in the other state: the situs state may tax (paragraph 1).
• Shares in a company whose assets consist principally of immovable property in one state: that state may tax (paragraph 4).
• Other shares representing at least 25% of the capital of a company resident in one contracting state: that state may tax (paragraph 5).
• Other property: taxable only in the transferor’s residence state (paragraph 6).

Article 13(5) deserves special attention in Vietnam-China M&A: when a Chinese parent transfers 25% or more of a Vietnamese subsidiary, Vietnam may tax the gains under the treaty — with Vietnamese law on tax on capital transfers supplying the computation rules. Below the 25% threshold (and outside paragraph 4), Article 13(6) provides that the gains are taxable only in the transferor’s state of residence — in this article’s typical scenario (a Chinese-resident company transferring shares in a Vietnamese company), the gains are taxable only in China; Vietnam has no taxing right. Exception: if the Vietnamese company’s assets consist principally of immovable property in Vietnam (paragraph 4), Vietnam may still tax the gains regardless of the holding percentage.

3.6. Employment income and other income

Salaries and wages from employment exercised in the other state may be taxed there (Article 15), with the familiar 183-day exceptions. Independent personal services (lawyers, engineers, accountants) fall under Article 14. These generate fewer DTA disputes in the FDI context, but businesses with Chinese specialists working long-term in Vietnam should watch the 183-day threshold.

4. Conditions for treaty benefits

Treaty rate caps are not automatic — the taxpayer must satisfy three conditions simultaneously:

1. Be a resident of a contracting state. Residence follows each country’s tax law (domicile, place of registration, head office…). For dual-resident individuals, Article 4 sets the tie-breaker order: permanent home → center of vital interests → habitual abode → nationality → mutual agreement. For dual-resident entities, the competent authorities agree.

2. Be the beneficial owner of the income. This is the decisive condition and the tax authority’s favorite audit target. Reduced rates or exemptions do not apply where the payment recipient is not the true lender/transferor, or income is passed through an intermediary lacking economic substance. Pure “conduit” structures to access the treaty (treaty shopping) will be denied. Businesses must evidence cash flows, disposal rights and the recipient’s economic substance.

3. The income must not be connected to a Vietnamese permanent establishment. If the beneficial owner carries on business in Vietnam through a PE and the income is effectively connected with it, Articles 10/11/12 do not apply — Article 7 (business profits) applies instead. A Vietnamese PE and treaty rate caps on PE-connected income cannot coexist.

5. Procedures for applying the treaty in Vietnam

Step 1: Classify the income and identify the treaty article. Categorize the payment (dividends/interest/royalties/service fees/transfers) and pinpoint the correct article — each carries different conditions and caps. Misclassification is the source of most DTA errors.

Step 2: Prepare proof of treaty eligibility. The core dossier: a Certificate of Residence issued by the Chinese tax authority for the relevant tax year; the contract or agreement generating the income; payment documents; evidence of beneficial ownership (ownership structure, financial statements, dividend resolutions…). The Certificate of Residence is mandatory — without it, the tax authority has no basis to apply the treaty.

Step 3: Notify/register with the Vietnamese tax authority. Treaty application procedures follow the 2025 Tax Administration Law and Circular 89/2026/TT-BTC. Depending on income type, treaty rates are applied through withholding by the Vietnamese payer (with complete supporting documents) or through a post-payment refund after tax was paid at domestic rates. Get the filing timing right — late filing can forfeit treaty-rate eligibility for that tax period.

Step 4: Declare, pay and retain records. The Vietnamese payer withholds, declares and pays tax at the determined rate; all treaty-eligibility evidence must be archived for later inspection. For recurring payments (quarterly interest, royalties), the dossier must be refreshed for each tax period.

Step 5 (in disputes): the mutual agreement procedure (MAP). New in Circular 95/2026/TT-BTC, MAP lets taxpayers ask both tax authorities to resolve cases of taxation not in accordance with the treaty. This matters when both countries tax the same income and ordinary credit relief cannot fix it. As a new regime, MAP practice in Vietnam needs time to develop — businesses facing difficulties should consult counsel early rather than wait. (Broader context: Chinese enterprises in Vietnam — managing opportunity and risk.)

6. The double-taxation elimination mechanism

Where income is lawfully taxed in both states under the treaty, Article 23 provides the credit method: each state allows a deduction from its own tax equal to the tax paid in the other state — capped at the domestic tax computed on that income.

Example: a China-resident company with Vietnam-source income taxed in Vietnam under the treaty may credit the Vietnamese tax against its Chinese tax, up to the Chinese tax on that income.

A special advantage for investors: tax sparing (Article 23(3)). Vietnamese tax exempted or reduced under economic development incentives is deemed paid — for dividends, interest and royalties, deemed at 10%. Vietnam’s tax incentives are thus not “clawed back” by Chinese tax: investors keep the incentive benefit when computing residence-country tax. Chinese enterprises enjoying Vietnamese CIT incentives (exemptions/reductions) should factor this into their Chinese tax filings.

7. Common risks and mistakes

1. No Certificate of Residence. Businesses apply treaty rates at payment time but cannot obtain the Certificate of Residence from the Chinese tax authority (or it covers the wrong tax year). On audit, all benefits are denied, with recovery of the tax difference plus penalties and late-payment interest. Rule: have the certificate in hand before applying preferential rates.

2. Not the beneficial owner but claiming the treaty anyway. A typical structure: a Chinese company receives royalties from Vietnam and passes almost all of them to a parent in a third country. The tax authority finds the Chinese company is a mere conduit and denies beneficial-owner status. Result: domestic-law rates apply, plus penalties.

3. Inadvertent permanent establishment. A Chinese contractor seconds teams to Vietnam for construction, installation or long-term technical support exceeding 6 months without PE planning. Once a PE is found, the 10% caps are lost for PE-connected income and all attributable profits become taxable in Vietnam.

4. Misclassifying income. Technical service fees involving technology transfer are reported as pure service fees (different contractor-tax ratios) when they are in substance royalties — or vice versa. Tax authorities recharacterize by substance, leading to recovery and misdeclaration penalties.

5. Still citing Circular 205/2013/TT-BTC. It ceased to be effective on 01/7/2026, replaced by Circular 95/2026/TT-BTC. Dossiers, internal procedures and contract templates citing the old circular need updating — especially tax clauses in new Vietnam-China contracts.

6. Ignoring obligations in China. Businesses compute only Vietnamese tax and forget the income must still be declared in China (the residence state), which applies the credit method for Vietnamese tax paid. Incomplete Chinese filing is a separate compliance risk, independent of having paid correctly in Vietnam.

7. Failing to keep evidence. Correct application but incomplete archiving of contracts, payment documents and residence certificates over the years. When a tax audit comes 3–5 years later, there is nothing left to defend the position taken.

8. Quick checklist
