Vietnam Transfer Pricing: GDT Rules, Decree 132 and Documentation

Vietnam applies the arm’s length principle to related-party transactions under the corporate income tax legislation, administered by the General Department of Taxation (GDT) within the Ministry of Finance. The instrument trail matters here, and it is stated plainly: our rules seed the regime from Circular 66/2013/TT-BTC, and Vietnam’s later framework — the transfer-pricing decree widely reported as Decree 132/2020 (ND-CP), with its implementing circulars — restates the methods, the documentation tiers and the reporting duties. This guide maps the framework at the level the sources support; the article-level citations, the forms and the monetary gates are the implementing detail the local practitioner confirms against the current decree and circular before the position is filed. Vietnam’s characteristic features are the short production clock (documentation within ten working days of a request), the related-party declaration the entity files in the annual cycle, and the reach of the rules into domestic related-party dealings.

The framework

Element	The content
The standard	The arm’s length principle for transactions between related parties: values and rates correspond to those independent parties would agree for comparable transactions; where they do not, the tax authorities re-determine the taxable income (the deductible-expense and revenue recomputation, on the mechanism the decree sets)
The scope	Transactions between related parties, cross-border and domestic; the related-party tests in the seeded guidance run on the capital/voting linkage (the participation percentage is recorded in our source as not verified — the decree’s thresholds the practitioner confirms)
The methods	The OECD set — the CUP, the resale price, the cost plus, the profit split, the TNMM — with the local guidance applying the comparable methods in a ranked order rather than the free best-method choice India and the OECD allow; the methods overview is the family, the local ranking the constraint
The range	The interquartile range (25th–75th percentile), the operating-margin indicators (OP/OC, OP/Sales), the Vietnamese entity typically the tested party
The documentation	The transaction-level supporting file, produced on request; the group tiers (master file, country-by-country reporting) arrive with the later decree family — our seeded rules record the local file only, and the current tier list is confirmed locally

The honest framing on the sources: Vietnamese guidance is OECD-based in method and OECD-plus in compliance — the arm’s length architecture, the comparability framework and the range mirror the Guidelines, while the local conditions (the ranked methods, the declaration duties, the language and certification practice) are additions our engine has not verified. A file built to the OECD standard travels well here; what it still needs is the local layer.

The documentation duty and the declaration

• The supporting file — the entity’s description and FAR, the controlled transactions, the method and the ranking rationale, the comparables and the adjustments, the range, the financials — the OECD Local File skeleton, with the Vietnamese guidance’s own content list.
• The production clock — ten working days from the tax authority’s request (the period our seeded rules record; the counting and the extension practice the local calendar confirms). Like Malaysia’s 14 days, this is a maintain-and-produce obligation: the file is retrieved, not written, and the reconstruction is the credibility failure the documentation weaknesses analysis prices.
• The declaration — the related-party reporting form the practice names as Form No. 01, filed through the government’s electronic portal. The point of principle for the group: the declaration obligation reaches domestic related-party transactions as well, so the Vietnamese entity’s related-party dealings are visible to the GDT annually, whether or not a border is crossed. The current form number, its attachments and its deadline are the implementing circular’s detail — confirmed locally.
• The contemporaneity — the documentation prepared in the annual cycle on the year’s actuals; our source records no verified statutory preparation date, and the retention period is likewise not recorded. The Indian 31 May window remains the group’s earliest fixed date, so the Vietnamese file follows the Indian one in practice.
• The language — not verified in our source; the practical expectation is a Vietnamese-language file for the examination, and the inspectorate’s requirement is confirmed with local counsel.

The examination and the penalty landscape

• The focus — our source flags royalty rates on related-party licensing as a principal audit focus, alongside the trading margins of the import/export entities and the cost bases of the manufacturing sites. The intangibles machinery (the DEMPE record, the benefit test, the benchmark) is the file’s pressure point.
• The selection — the risk-based examination within the annual tax inspection; the CbCR-based indicators, where the group files them, are the international case-selection input as elsewhere (CbCR guide).
• The consequence — our rules record no verified penalty rate. The mechanism the sources describe: the underpayment reduces the deductible expense and/or increases the income, interest accrues on the late payment, and administrative fines attach under Vietnamese tax procedure for the procedural breaches — the rates and the fine bands are the procedure law’s, confirmed locally.
• The relief — MAP under the treaty network; our seeded rules record no safe harbour and no verified APA practice (the local confirmation applies on both), so the Vietnamese position is argued on the benchmark.

The Vietnam-India reading

Vietnam is the sourcing shift jurisdiction for Indian groups — the manufacturing destination the group adds when the China-plus-one decision moves production, and the node that then sits on the same supply chain as the Indian entity:

The pattern	The Vietnamese question	The Indian mirror
The Vietnamese factory selling to India	The export price to the Indian affiliate/entity — the manufacturer’s return, the cost base, the ranked-method choice	The Indian importer’s customs and TP reading of the same invoice
The Vietnamese factory selling onward to the group	The contract or routine manufacturer’s margin, the IP-light profile, the royalty it pays	The group’s contract manufacturing characterization, and the Indian entity’s own margin where it is the principal
The technology/licence flow	The royalty out of Vietnam — the rate, the DEMPE support, the deductibility	The Indian TDS and characterization of the mirror payment where the Indian entity is the licensee

Same economics, two files — and in Vietnam’s case a third artefact: the annual related-party declaration, whose numbers must agree with the documentation and with the financial statements. The group that documents once, to the OECD standard, and then adds the local layer (the ranked method, the declaration schedule, the language) serves Hanoi and Delhi from one dataset; the group that reverse-engineers the file after a request meets the ten-working-day clock with nothing to put on it.

The working position for the group with a Vietnamese node

1. Fix the characterization and the method ranking — manufacturer, distributor, service entity — then apply the method the local guidance ranks for that fact pattern, documenting why the preferred method was unavailable if a lower-ranked one is used.
2. Benchmark the Vietnamese tested party — the local cost base, the ASEAN comparables, the interquartile range; the royalty and service-fee streams separately supported, since they are the audit’s focus.
3. Build to the ten-working-day standard — the file, the transfer schedules behind the Form No. 01 declaration, and the reconciliation to the accounts, in the annual cycle; the domestic related-party dealings included.
4. Reconcile with India before the examination does it — the invoice prices, the customs values, the Indian file’s characterization, the treaty positions, and the MAP route identified where the two administrations can otherwise adjust the same margin twice.
