Strategic Use of the Profit Split Method in Transfer Pricing: When, Why and How

Transfer pricing regulations aim to ensure that profits in cross-border group transactions are aligned with where real economic value is created. Indian law, consistent with global practice, applies the Arm’s Length Principle to achieve this. Among the six recognised methods, the Profit Split Method (PSM) is often discussed but comparatively less applied in practice, primarily because it is suitable only in specific, complex scenarios.

This article explains the conceptual foundation of PSM, its two main variants, how the method is practically implemented, and how Indian courts and tribunals have evaluated its use. It concludes with practical guidance for businesses that may need to consider PSM in their transfer pricing strategy.

Position of Profit Split Method in Indian Transfer Pricing

Most traditional transfer pricing methods are one-sided. For example, under TNMM, the assessee (or its Associated Enterprise) carrying out relatively less complex, low-risk or routine functions is chosen as the tested party. Its operating margins are then compared against those of independent enterprises performing similar functions and bearing similar risks.

This approach works reasonably well so long as:

  • One entity clearly performs routine or limited-risk functions; and
  • The other entity (or entities) carries most of the strategic, high-value, or intangible-heavy functions and risks.

However, this assumption breaks down where:

  • Both parties are deeply involved in value creation;
  • Both bear significant risks; or
  • Both contribute unique intangibles or specialised functions.

In such circumstances, identifying a tested party becomes contentious, and a one-sided method may not appropriately capture the economic reality. That is precisely where PSM is designed to operate.

Core Concept of PSM

Instead of isolating one entity and benchmarking its margin, PSM:

  • Aggregates the combined profits arising from the relevant international transaction (or a group of closely connected transactions); and
  • Splits this combined profit between the Associated Enterprises based on their relative contributions, evaluated through:
    • Functions performed,
    • Assets employed (including intangibles), and
    • Risks assumed (FAR analysis).

In essence, PSM addresses the question:

When two or more Associated Enterprises jointly generate profits from integrated activities, how should that profit be allocated between them as if they were independent parties dealing with each other at arm’s length?

When PSM Typically Becomes Relevant

PSM generally comes into the picture when:

  • Both entities contribute unique and valuable intangibles (e.g., technology, patents, trademarks, proprietary processes);
  • Activities are highly integrated, so that individual transactions or segments cannot reasonably be evaluated in isolation;
  • There is joint development of products, intellectual property, or business platforms;
  • Reliable external comparables for a one-sided method are not available, especially due to the presence of non-routine intangibles on both sides; or
  • The functional profile of a so-called “routine” entity has evolved over time into a more complex, value-generating role.

Indian transfer pricing authorities, as well as OECD guidance, tend to support PSM in these types of situations, while being cautious about its use where facts do not justify it.

Approaches Under Profit Split Method

Once it is concluded that PSM is the most appropriate method, the next crucial step is to determine how profits should be divided. Broadly, there are two ways to execute PSM:

  1. Contribution Analysis (Combined Profit Split)
  2. Residual Profit Split

Both aim to arrive at the arm’s length allocation of profit, but the sequence and emphasis differ.

Contribution Analysis (Combined Profit Split)

Under the contribution analysis approach, the entire combined operating profit of the relevant transaction(s) is directly allocated among the parties according to a suitable allocation key that reflects their relative contributions.

Key Characteristics

  • No prior distinction between “routine” and “non-routine” profits;
  • The entire profit pool is divided in one step;
  • The allocation key must reliably mirror value creation, not just cost or revenue sharing for convenience.

Common allocation keys could be:

  • Relative R&D expenditure attributable to the transaction;
  • Asset base (particularly intangible assets) utilised for the transaction;
  • Headcount or seniority-weighted employee costs in R&D or strategic functions;
  • Other economically meaningful measures derived from a robust FAR analysis.

Conceptual Steps

To arrive at the arm’s length profit through contribution analysis, a structured four-step process is often followed:
