Transfer Pricing: Vietnam vs Australia

Transfer pricing is where tax law meets the invoice. Vietnam and Australia both enforce the arm’s length principle — related-party transactions must be priced as if between independents — but their documentation and enforcement machinery differ. Vietnam runs a three-tier documentation system under Decree 255/2026/ND-CP (which replaced Decree 132/2020/ND-CP and applies from the 2026 corporate income tax period); Australia enforces through Division 815 of the Income Tax Assessment Act 1997 with its own documentation expectations. Get the file right before the audit, not during it.

Vietnam: three tiers under Decree 255/2026

Vietnam’s transfer-pricing rules require the master file, local file and country-by-country report (CbCR) for taxpayers meeting the thresholds, filed with the annual CIT finalisation. Decree 255/2026/ND-CP is the current framework (replacing Decree 132/2020/ND-CP, applicable from the 2026 corporate income tax period): related-party definition, arm’s length methods, deductible-expense caps for certain transactions — taxpayers apply the new decree’s thresholds, methods and filing mechanics from the 2026 tax period onward. Vietnam also operates advance pricing agreements (APAs) for qualifying taxpayers, and tax authorities increasingly use CbCR and related-party disclosure data to select audit targets.

Australia: Division 815 and documentation

Australia’s transfer-pricing rules live in Division 815 of the ITAA 1997 (with Subdivisions 815-B for treaty cases, 815-C and 815-D), applying the arm’s length principle to international related-party dealings. The ATO expects contemporaneous documentation demonstrating the arm’s length nature of pricing — prepared before the tax return is lodged — and applies significant penalties where documentation is absent or inadequate (the “reasonably arguable position” standard matters). Australia also has CbCR obligations for significant global entities, thin-capitalisation rules, and an active APA program. Audits are data-driven and the ATO publishes detailed guidance on its risk-assessment frameworks.

Key differences

Documentation timing: Vietnam’s files attach to the annual finalisation cycle; Australia demands documentation be ready before lodgment. Penalties: both sting, but Australia’s penalty regime explicitly scales with documentation quality. Methods: both accept the OECD-recognised methods (CUP, resale price, cost plus, TNMM, profit split) — the divergence is in administrative practice, comparability expectations and safe harbours, not in the method list. Disputes: both offer mutual agreement procedure (MAP) under the treaty network; Vietnam–Australia MAP cases follow the bilateral treaty.

Practical guidance

Groups operating Vietnam–Australia should maintain one coherent transfer-pricing policy documented consistently in both countries’ files — contradictions between the Vietnamese local file and the Australian documentation are audit bait. Benchmark with regional comparables, refresh the analysis when business models change, and apply Vietnam’s Decree 255/2026 framework (from the 2026 CIT period). Consider APAs for material, stable flows.

Checklist

Vietnam: prepare master/local/CbCR per thresholds; apply Decree 255/2026 (from the 2026 CIT period).
Australia: complete contemporaneous documentation before return lodgment.
Both: apply OECD methods consistently; keep one coherent policy.
Both: use regional comparables; refresh on business-model change.
Disputes: consider MAP under the Vietnam–Australia treaty.

Frequently asked questions

Which decree governs Vietnamese transfer pricing now?

Decree 255/2026/ND-CP is the current framework — it replaced Decree 132/2020/ND-CP and applies from the 2026 corporate income tax period. Apply the new decree’s thresholds and filing rules.

What is the arm’s length principle?

The requirement that related-party transactions be priced as independent parties would price them — the global standard both Vietnam and Australia apply.

Does Australia require documentation before filing?

Effectively yes: the ATO expects contemporaneous documentation in place before the return is lodged, and penalties scale with its absence or inadequacy.

Can we use one set of comparables for both countries?

Often yes — regional comparables can serve both files — but each country’s documentation must stand on its own logic and local requirements.

What if the two tax authorities disagree?

The mutual agreement procedure under the Vietnam–Australia tax treaty lets the competent authorities negotiate relief from double taxation. APAs can prevent the dispute upfront.
