Recent case law and administrative guidance across the EU, Singapore, and Australia confirm that transfer pricing (TP) arrangements are no longer just an income tax concern – they have direct and often overlooked implications for VAT/GST.
The Core Link
A transfer price is, in essence, the consideration for a supply. Under VAT/GST, the tax base is the consideration (subjective value). Therefore, any TP adjustment – whether made by the taxpayer (year‑end compensatory adjustments) or by a tax authority (primary/corresponding adjustments) – may require a corresponding adjustment to the VAT/GST due and input tax credits.
When VAT/GST Departs from Subjective Value
Special anti‑avoidance rules (SAARs), specific rules in tax law designed to target and prevent particular, well-defined tax avoidance arrangements or transactions in the EU, Singapore, and Australia replace the agreed consideration with an open market value when:
-
Parties have a special relationship (related parties, associates, close ties); and
-
The recipient is not entitled to a full input tax credit (e.g., financial institutions, insurers, partly exempt businesses).
The EU rule covers both over‑pricing and under‑pricing; Singapore and Australia focus mainly on under‑pricing. A key open question remains: does “open market value” for VAT/GST equal the arm’s length price under OECD TP Guidelines? Not necessarily – the answer may depend on the TP method used.
TP Adjustments: What Triggers VAT/GST?
| Type of Adjustment | VAT/GST Consequence |
|---|---|
| Party‑induced (e.g., year‑end TNMM settlement) | Generally requires VAT/GST adjustment (the consideration has changed). |
| Administration‑induced for income tax only (no link to a supply) | No VAT/GST consequences (per AG Kokott in Stellantis Portugal). |
| Variable price adjustment under contract (based on actual costs) | VAT price adjustment – not a separate supply. |
Administrative concession (EU & Singapore): Where all parties have a full input tax credit, adjustments create a zero‑sum game. Tax authorities generally accept no VAT/GST adjustment to reduce compliance burden.
Singapore’s IRAS e‑Tax Guide confirms this, provided the adjustment is effected through financial statements (and for decreases, also taxable/allowable for income tax).
Critical Lessons from Arcomet (CJEU)
A Belgian parent and Romanian subsidiary had a TNMM contract. If the subsidiary exceeded its profit margin, it paid the excess to the parent as “consideration for services”, with a formal VAT invoice. The CJEU held this was an in‑scope taxable supply – the contractual language and invoicing were decisive. Incoherent treatment (in‑scope in two years, out‑of‑scope in the third) attracted tax authority scrutiny.
If the intention is not to create a separate taxable supply, frame post‑supply TP settlements as mere price variations of the original supply, not as new consideration for additional services.
Takeaways
-
Collaborate across teams – TP and VAT/GST specialists must work together from the contract drafting stage.
-
Review contractual language – Words like “consideration for services” trigger VAT/GST. Use price adjustment clauses instead where possible.
-
Document everything – Choice of TP method, open market value at transaction date, and reasons for (non‑)treatment of adjustments in VAT/GST.
-
Consider advance rulings – Available in Singapore, Australia, and many EU countries (though an EU ruling does not bind other member states).
-
Monitor pending cases – The CJEU’s final judgment in Stellantis Portugal (AG Kokott’s opinion favours VAT price adjustment treatment) will provide further clarity.
Final Word
Tax authorities are increasingly coordinating between TP and VAT/GST divisions (e.g., HMRC requires cross‑department communication).
A coherent, well‑documented strategy is no longer optional – it is essential to avoid audits, penalties, and double taxation.
