A Chinese parent company transfers technology to its Vietnamese subsidiary — a routine transaction for multinational groups. Yet three questions keep legal and finance teams awake: must the technology transfer contract be registered, where, and what taxes apply? This guide answers all three under the legal framework in force as of October 2026.
1. Registration of the technology transfer contract is mandatory
A technology transfer (TT) contract from a Chinese parent to its Vietnamese subsidiary must be registered with the state management authority for science and technology, under Article 31 of the Technology Transfer Law 07/2017/QH14 — as amended by Clause 14, Article 1 of Law 115/2025/QH15 (promulgated 10/12/2025, effective 01/4/2026).
A critical update: Decree 76/2018/ND-CP expired on 01/4/2026 and was replaced by Decree 101/2026/ND-CP (issued 31/3/2026, effective 01/4/2026). All TT registration dossiers from April 2026 onward follow this new decree.
Authority issuing the TT Registration Certificate under Article 21 of Decree 101/2026/ND-CP:
- The Ministry of Science and Technology — for standalone technology transfers from abroad into Vietnam;
- The provincial Department of Science and Technology — for technology transfers within an investment project.
Identifying the correct authority up front avoids rejected dossiers and delays. Note that registering a TT contract (with the science and technology authority) is not the same as registering a licensing contract with the Intellectual Property Office of Vietnam — two separate procedures with different purposes.
2. VAT: technology fees are not subject to VAT — but watch the bundling trap
Under Clause 21, Article 5 of the VAT Law 2024 (No. 48/2024/QH15, effective 01/7/2025), technology transfer under the Technology Transfer Law is not subject to VAT. Note: “not subject to VAT” is different from “0% rate” and different from “exempt” — three entirely different tax treatments.
The biggest trap sits in Clause 13, Article 4 of Decree 181/2025/ND-CP: for a contract combining technology transfer with machinery and equipment where the technology value cannot be separately identified, the entire contract value is subject to VAT.
Example: a VND 12 billion contract — technology worth VND 4 billion, equipment line worth VND 8 billion — stated as one lump sum without breakdown. The whole VND 12 billion becomes subject to VAT, and the VAT advantage on the technology portion is lost. Separate the technology value in the contract itself; never state “technology transfer is not subject to VAT” without this exception.
3. Foreign contractor CIT: 10% withheld and paid by the Vietnamese subsidiary
Technology fees paid by the Vietnamese subsidiary to the Chinese parent are subject to foreign contractor corporate income tax at 10% of the total turnover paid to the Chinese side, under Clause 3, Article 12 of Decree 320/2025/ND-CP. The calculation method is guided by Article 7 of Circular 20/2026/TT-BTC (effective 12/3/2026).
The Vietnamese party must withhold, declare and pay this tax on behalf of the foreign contractor. Declaration procedure under Article 30 of Circular 89/2026/TT-BTC (issued 30/6/2026, effective 01/7/2026):
- Declare per each payment occurrence;
- If payments occur multiple times within a month, the payer may register for monthly declaration;
- File a finalization declaration when the contract ends.
From 01/7/2026, Circular 103/2014/TT-BTC has been abolished (Article 99 of Circular 89/2026). Update contractor tax processes to the new framework: Circular 89/2026 (procedure), Circular 20/2026 and Decree 320/2025 (calculation).
4. Intra-group transfer pricing: the parallel compliance track
The Chinese parent – Vietnamese subsidiary relationship is an associated relationship under Article 5 of Decree 255/2026/ND-CP (effective 01/7/2026, replacing Decree 132/2020/ND-CP and Decree 20/2025/ND-CP). Consequences:
- Technology fees between the two companies must follow the arm’s length principle;
- The company must file the related-party transaction appendix, except cases eligible for exemption from transfer pricing documentation under Article 20 of this decree;
- Under Article 18 of Decree 101/2026/ND-CP on TT pricing and payment, the tax authority may request a valuation of the technology between related parties.
In other words, the technology fee is not merely an internal group arrangement — it must withstand scrutiny by the Vietnamese tax authority, a point Chinese groups entering Vietnam often underestimate.
5. The Vietnam – China Double Taxation Agreement: do not expect a tax cut
Article 12 of the 1995 Vietnam – China DTA caps source-country tax on royalties at 10% — exactly equal to the domestic rate. The agreement creates no actual tax reduction for technology fees paid to China; no article should promise “tax savings via the treaty”.
The real value of the treaty is on the Chinese side: the parent company may credit the tax paid in Vietnam when finalizing tax in China (Article 23), including tax sparing — taxes exempted or reduced in Vietnam are deemed paid at 10% (Clause 3, Article 23).
Treaty relief procedure under Article 78 of Circular 89/2026/TT-BTC: file with the tax declaration of the first declaration, including:
- Application form 01/HTQT (Appendix III of the circular);
- Certificate of residence issued by the Chinese tax authority, duly consular-legalized;
- A copy of the contract certified by the taxpayer;
- Authorization document (if any).
6. Action checklist
- Identify the correct TT registration authority: the Ministry or the provincial Department of Science and Technology (Article 21, Decree 101/2026);
- Split the technology value out in the contract to avoid the VAT trap (Clause 13, Article 4, Decree 181/2025);
- Set up the 10% foreign contractor CIT withholding – declaration – payment process under the Circular 89/2026 framework;
- Prepare transfer pricing documentation: arm’s length pricing, related-party appendix (Decree 255/2026);
- Complete treaty relief paperwork from the first tax declaration (Article 78, Circular 89/2026), with the residence certificate consular-legalized.
