Plain English
When you sell early-stage IP inside the group, nobody can really know what it is worth. The HTVI approach lets tax authorities look at what actually happened afterwards and use that as evidence that the original valuation was wrong — a rare exception to the rule that hindsight is not allowed.
Technical definition
Intangibles or rights in intangibles for which, at the time of their transfer between associated enterprises, no sufficiently reliable comparables exist and the projections of future cash flows or income expected to be derived, or the assumptions used in valuing the intangible, are highly uncertain.
Why it matters
It shifts valuation risk onto the taxpayer for many years after the transaction, and it is the reason contemporaneous valuation evidence must be preserved.
How it works in practice
- 01Assess whether the intangible meets the HTVI characteristics at transfer.
- 02Prepare and retain the valuation, assumptions, and risk weighting used at the time.
- 03Monitor actual outcomes against projections.
- 04If outcomes diverge materially, be ready to show the divergence was unforeseeable or arose from events outside control.
Worked example
Phase II compound
A compound is transferred at 30m based on risk-adjusted projections. Five years later it is approved and generates 900m in cumulative sales. Under the HTVI approach the authority may presume the original price was not arm's length unless the taxpayer can show the projection process was sound and the outcome resulted from a genuinely unforeseeable event.
Common mistakes
- Discarding the working files behind the original valuation.
- Using unadjusted management optimism as the projection base.
- No mechanism in the agreement for contingent pricing.
Audit red flags
- Large one-off IP migration with a single-scenario DCF.
- Discount rate chosen without documented derivation.
Documentation & data
Documents to hold
- Valuation report with scenarios and probability weighting.
- Evidence of what was known at the transfer date.
- Price adjustment clauses, milestone or earn-out terms.
Data you need
- Contemporaneous forecasts and board approvals.
- Discount rate build-up.
- Subsequent actuals for monitoring.
Who owns this internally: Group tax with corporate development and valuation specialists.
Jurisdiction notes
- OECD
- Chapter VI, Section D.4 and the 2018 implementation guidance set out the approach and its exemptions.
- European Union
- Several member states have adopted domestic price-adjustment clauses with their own look-back windows.
Notes by role
In-house tax teams
Create a retention protocol for valuation working files at the moment of transfer. Ten years later nobody remembers where they were saved.
Frequently asked
- Is HTVI retrospective taxation?
- The OECD frames ex post outcomes as presumptive evidence about the ex ante pricing, not as a substitute for it. Taxpayers can rebut.

Valuation-literate transfer pricing people are scarce. Learning DCF mechanics pays off quickly.
