Transfer Pricing Compliance in Vietnam for US Multinationals: What’s Different Without a Tax Treaty
The short answer
US multinationals operating Vietnamese subsidiaries must comply with Vietnam’s transfer pricing framework — now Decree No. 255/2026/ND-CP, effective 1 July 2026 — on the same arm’s-length basis as any other foreign investor. The added complication for US groups specifically: there is no US-Vietnam double tax treaty in force, so there is no treaty-based Mutual Agreement Procedure (MAP) to resolve double taxation if the Vietnamese and US tax authorities reach different conclusions about the same intercompany price. That makes getting the position right the first time — rather than relying on a treaty dispute-resolution mechanism afterward — considerably more important for US groups than for investors from treaty countries.
Why US groups face a harder version of the same problem
For most foreign investors, if Vietnamese tax authorities adjust an intercompany price, a DTA’s MAP article provides a channel for the two countries’ competent authorities to negotiate a coordinated resolution and avoid double taxation. Without a US-Vietnam treaty, a Vietnamese transfer pricing adjustment on a US group’s intercompany transaction has no equivalent formal bilateral channel — the US parent may end up taxed on the same income in both countries with no treaty mechanism to eliminate the overlap, relying instead on the US unilateral Foreign Tax Credit, which does not always fully offset the Vietnamese adjustment plus penalties and interest.
Practical consequences for US-parented Vietnamese entities
Documentation quality is the primary defense, not a treaty MAP. Robust local file and master file documentation, prepared before filing rather than reconstructed during an audit, is the main tool available to a US group to defend its pricing.
Intercompany agreements need to be commercially real. Management service agreements, IP licenses, and financing arrangements between a US parent and Vietnamese subsidiary should reflect genuine functions, assets, and risks — increasingly scrutinized under both Decree 255 and the substance-based approach introduced by Circular 95/2026/TT-BTC for cross-border tax positions generally.
US GAAP/US tax reporting and Vietnamese transfer pricing filings should be reconciled. Inconsistencies between what is reported to the IRS (e.g., under Section 482 and CbCR requirements) and what is filed in Vietnam are a common audit trigger.
Advance Pricing Agreements (APAs) deserve serious consideration. Vietnam’s APA program, referenced alongside the new DTA guidance under Circular 95/2026/TT-BTC, allows a taxpayer to agree pricing methodology with the tax authority in advance — a more valuable tool for US groups precisely because it doesn’t depend on the treaty MAP process being available.
Where we see US groups exposed
Regional or global management fees charged into the Vietnamese entity without a documented benefit test.
US parent loans to the Vietnamese subsidiary priced off US benchmark rates without local market validation.
IP or brand licensing fees set as a percentage of revenue without transfer pricing study support.
Assuming US transfer pricing documentation (Section 482 studies) is sufficient for Vietnamese filing purposes — it generally is not, and a separate Vietnam-compliant local file is required.

FAQ
Does the lack of a US-Vietnam tax treaty affect transfer pricing compliance?
Yes — indirectly, by removing the Mutual Agreement Procedure that would otherwise help resolve double taxation from a transfer pricing adjustment.
Can US groups still get an Advance Pricing Agreement in Vietnam?
Vietnam’s APA program is available to taxpayers generally and is a particularly valuable tool for US groups given the absence of treaty-based dispute resolution.
Is a US Section 482 transfer pricing study enough for Vietnam filings?
No — a separate, Vietnam-compliant local file and supporting documentation is required under Decree 255/2026/ND-CP.
