Every transfer pricing method rests on a comparison, and a comparison only works once you know what is being compared. The functional analysis supplies that. It comes before the benchmarking study, before the choice of profit level indicator and before any range is calculated. Interest in the topic is rising. According to a smartZebra review of market search data, monthly German searches for "Funktionsanalyse" tripled in a year: from 180 in October 2025 to 590 in September 2026.
What does a functional analysis examine?
A functional analysis examines three things for each party to a transaction: the functions it performs, the assets it uses and the risks it assumes. Practitioners call this the FAR profile. The OECD Transfer Pricing Guidelines define the exercise at paragraph 1.51:
"This functional analysis seeks to identify the economically significant activities and responsibilities undertaken, assets used or contributed, and risks assumed by the parties to the transactions."
The same paragraph adds two points that shape how the analysis is done. First, it is the economic significance of the functions "in terms of their frequency, nature, and value" that matters, not the number of functions on a list. Second, it is important to understand how value is generated by the group as a whole and how the parties' functions depend on each other.
Functions are the activities: research and development, procurement, production, marketing, sales, logistics, and the management decisions behind them. Assets include plant and equipment, valuable intangibles and financial assets, according to paragraph 1.54. Risks are the uncertainties that can change the outcome, such as market, inventory, credit or product liability risk.
Why do risks need their own analysis?
Risks need their own analysis because a contract can place a risk on a party that has no real say over it. Paragraph 1.56 of the OECD Guidelines states that a functional analysis "is incomplete unless the material risks assumed by each party have been identified and considered". Paragraph 1.60 sets out a six-step framework, often referred to as the risk control framework:
- Identify the economically significant risks with specificity.
- Determine how the contract assigns them.
- Determine through the functional analysis how each party actually operates in relation to the assumption and management of these risks.
- Check whether the contractual assumption matches the conduct.
- Where the party assuming a risk does not control it or lacks the financial capacity to bear it, allocate the risk under the Guidelines' risk allocation guidance.
- Price the transaction, taking into account the consequences of the risk assumption.
Two tests drive steps four and five. Control over risk (paragraph 1.65) means the capability to decide whether to take on, lay off or decline a risk-bearing opportunity, and actually making that decision. It also covers deciding whether and how to respond to the risk. Financial capacity (paragraph 1.64) means access to funding to take on the risk, pay for its mitigation and bear the consequences if it materialises. Paragraph 1.98 allocates the risk to the party that meets both tests.
The consequence can be stark. The Guidelines work through an example at paragraph 1.103. A company that funds an activity but exercises no control over the financial risk would be entitled to no more than a risk-free return. Money alone does not earn the upside.
How does the functional profile pick the tested party?
The functional profile picks the tested party because a one-sided method can only be applied reliably to the simpler side of a transaction. Paragraph 3.18 of the OECD Guidelines states the rule:
"As a general rule, the tested party is the one to which a transfer pricing method can be applied in the most reliable manner and for which the most reliable comparables can be found, i.e. it will most often be the one that has the less complex functional analysis."
A contract manufacturer that produces to order, owns no valuable intangibles and bears little market risk has a simple profile. Independent companies with similar profiles exist, and their margins are published. The principal that designed the product, owns the brand and carries the market risk does not have obvious independent twins. So the contract manufacturer is tested, and the principal keeps the residual profit or loss.
Which method fits which functional profile?
The method that fits is the one the OECD Guidelines call the most appropriate to the circumstances. Paragraph 2.2 lists the criteria, and one of them is "the appropriateness of the method considered in view of the nature of the controlled transaction, determined in particular through a functional analysis". The Guidelines then attach typical profiles to each method:
The table shows tendencies, not rules. Paragraph 2.3 keeps a preference for the traditional transaction methods, and for the comparable uncontrolled price method (CUP), where they are equally reliable. If a genuine market price for the same product exists, the functional profile does not override it. The TNMM is common for routine profiles because it tolerates functional differences better than price or gross-margin methods. Our article on choosing a transfer pricing method covers this in detail.
The profit split starts where the one-sided logic breaks. Paragraph 2.65 allows a one-sided method where one party makes all the unique and valuable contributions and the other makes none. Paragraph 2.130 defines those contributions as ones that are not comparable to what independent parties contribute and that are a key source of economic benefit. When both sides make them, there is no simple party left to test.
Where do intangibles fit in?
Intangibles fit into the functional analysis through the functions performed around them, not through legal title. Paragraph 6.32 of the OECD Guidelines points to the functions of development, enhancement, maintenance, protection and exploitation of intangibles, commonly shortened to DEMPE. Paragraph 6.42 is explicit that legal ownership, by itself, does not confer any right to retain the returns from exploiting an intangible.
For the method, this matters twice. A company that holds a patent but outsources every DEMPE function may turn out to be the simpler party. And paragraph 6.56 names the functions of special significance, such as the design and control of research and marketing programmes and the management of budgets. Whoever performs those is unlikely to be a routine entity.
How is a functional analysis done in practice?
A functional analysis is done by combining documents with interviews. In practice, five steps recur:
- Map the value chain of the group and place each entity in it.
- Read the contracts to see which functions and risks each entity has on paper.
- Interview the people who make the decisions: management, sales, R&D, finance, supply chain.
- Compare paper and conduct, risk by risk, using the control and financial capacity tests.
- Characterise each entity, choose the tested party and record why the method follows.
The result is not only an internal working paper. Annex II to Chapter V of the OECD Guidelines requires the local file to contain "a detailed comparability and functional analysis" and the reasons for selecting the method. The master file adds a brief functional analysis describing the principal contributions to value creation by individual group entities, as our article on master file and local file explains. Germany writes these requirements into law. Section 1(3) sentence 2 of the Foreign Tax Act names the functional and risk analysis. Section 4(1) no. 3 of the documentation regulation (GAufzV) requires a description of the value chain. Our German article on the Funktionsanalyse covers those rules.
What happens after the functional analysis?
After the functional analysis comes the benchmark. The profile tells you whom to test and which profit level indicator fits. The comparables must then share that profile, which is where the benchmarking study behind an arm's length price is won or lost. A routine distributor tested against full-fledged distributors inflates the range. A contract manufacturer tested against companies with their own brands does the same.
Benchmarking Pro, part of the smartZebra transfer pricing module, is built for this step. It screens 50,000+ public and 500,000+ private companies with filters for independence, losses and R&D intensity, SIC and NAICS classification, and country and size. It calculates the indicators the profile calls for, including EBIT margins, Berry ratios and return on costs, with the interquartile range and median. Every data point links back to the original annual report, and the full benchmarking appendix exports in one click.
The functional analysis decides what a fair price looks like. The benchmark proves it.
