A benchmarking analysis is a comparability study that shows, for transfer pricing purposes, whether prices or margins between related parties are at the level usual between independent companies. Its output is an arm’s length range of a chosen indicator, most often a profit margin, expressed as an interquartile range. If the tested company’s result falls within that range, its pricing is considered compliant with the arm’s length principle; if not, an adjustment of the tax base is at risk.
What a benchmarking analysis is and what it is for
A benchmarking, or comparability, analysis is a key part of transfer pricing documentation. Its role is to prove that a transaction between related parties is set as independent parties would agree it on the market. Instead of the abstract claim “our price is at market level”, the analysis brings concrete figures from real comparable companies.
The output is not a single “correct” number but a range of values within which comparable independent companies operate. This range serves as a yardstick: if the tested company’s profit margin or price fits inside it, the pricing holds up. The analysis thus protects the company during a tax audit and helps set intra-group prices defensibly. When the transfer pricing obligation arises in the first place, we explained in our article on transfer pricing documentation.
How it relates to the arm’s length principle
The foundation of transfer pricing is the arm’s length principle. Under it, prices between related parties should be the same as between independent firms under comparable conditions. In Slovakia it is anchored in Section 18 of the Income Tax Act and further detailed by guidelines of the Ministry of Finance, which build on the OECD Transfer Pricing Guidelines.
The benchmarking analysis is the practical tool by which this principle is demonstrated. It is not enough to declare that a price is usual – it must be backed by data on the actual market. That is why the comparability study is the core of full documentation and is increasingly expected by the tax authority for companies with cross-border intra-group transactions.
Choosing the tested party and the indicator
The first step is identifying the tested party, that is the party to the transaction with simpler functions, fewer risks and no unique intangible assets. The tested party is usually the entity for which enough comparable independent companies can be found. For a distributor that merely buys and resells the group’s branded goods, for example, the distributor is typically the tested party.
The second step is choosing the profit level indicator that best captures the profitability of the function. Common choices include the operating margin on sales, the net cost plus mark-up or the return on assets. Both the indicator and the tested party must match the functional and risk analysis of the transaction; without it, the whole study loses its footing.
How the search for comparable companies works
The heart of the analysis is finding independent firms with a similar activity. In practice, commercial databases are used, especially Amadeus, Orbis and the TP Catalyst module from Bureau van Dijk, which hold financial data of European companies. The search is run using criteria such as industry classification (NACE), region, size and availability of financial statements.
The automatic selection is only the start. It is followed by a manual screening that removes companies which are not genuinely comparable – for example related entities, firms with losses from extraordinary causes, or businesses with a different model. Example: the database returns 300 firms, but after manual review only 15 truly comparable ones remain. The quality of this step decides how defensible the whole analysis is.
What the interquartile range means and how to read it
From the financial data of comparable firms an arm’s length range of the indicator is calculated. To exclude extreme, distorting values, the interquartile range is used – the span between the 25th percentile (lower quartile) and the 75th percentile (upper quartile). Values in this band are treated as usual, at market level. The middle value, the median, serves as a reference point.
The interpretation is straightforward: if the tested company’s profit margin lies inside the interquartile range, its pricing complies with the arm’s length principle. If it lies outside, there is a risk the tax authority will adjust the tax base – usually to the median or to the nearest edge of the range. Example: if the market range of the operating margin is 3% to 7% and the firm reports 1%, an audit may assess tax up to the median level.
How often to update the benchmark and what an audit checks
A benchmarking analysis is not a one-off document. It is recommended to refresh the financial data of comparable firms every year and to renew the whole comparability study (a new company search) usually after three years, provided the transaction circumstances have not changed. This keeps the arm’s length range aligned with current data rather than a situation from years ago.
During a tax audit the authority examines above all the logic of selecting the tested party, the appropriateness of the indicator, the quality of the screening and whether the firm actually keeps its results within the arm’s length range. An insufficiently justified selection of comparable companies is the most frequent target of objections, so it pays to document the reasoning behind every step. The same documentation is often scrutinised by buyers during due diligence before selling a company.
Do you need to prepare or defend a benchmarking analysis and set intra-group prices so they hold up in an audit?
FAQ
When does a company need a benchmarking analysis?
A benchmarking analysis is part of the full transfer pricing documentation kept mainly by companies with significant cross-border transactions with related parties. Simplified documentation usually does not require a detailed comparability study. The scope of obligations depends on the type of transaction and whether it is domestic or cross-border, so verify the required level of documentation in advance for your case.
What does the interquartile range mean?
The interquartile range is the span of values between the 25th and 75th percentile of comparable companies’ results. It excludes the extreme values at both ends that would distort the market range. If the tested firm’s indicator lies inside this range, its prices are considered to be at arm’s length. The middle value, the median, serves as a reference point and often as the target of any tax adjustment.
What happens if the margin is outside the range?
If the tested company’s profit margin or price lies outside the interquartile range, the tax authority may adjust the tax base during an audit. The adjustment is usually made to the median or to the nearest edge of the arm’s length range, leading to additional tax and possible penalties. It therefore pays to monitor prices continuously and keep them within the market band throughout the year.
