O&W Analytics

In Olesiński & Wspólnicy we attentively watch trends and directions of tax regulations. Increasingly, apart from knowledge of legal regulations, advanced analytical knowledge and appropriate mathematical and statistical skills, come into play. To address the needs arising from the new regulations, we created a new entity – O&W Analytics.

Its specialists are supporting O&W Clients in implementation of tax law-compliant transfer pricing models, based on professional analyses of comparative data (benchmarking).

Transfer pricing and analysis of comparative data

Effective January 2017, requirements concerning obligatory transfer pricing documentation were extended. A significant number of taxpayers shall, apart from development of „traditional” documentation in descriptive form, be obligated to prove that prices and margins established in transactions with related parties are in line with terms and conditions agreed in transactions between third parties (Arm’s length principle). Analysis shall be based on collected comparative data.

Analyses of comparative data often consist of complex financial models requiring access to unique (restricted) financial data and comprehensive knowledge in the field of finance, risk assessment, statistics and econometrics.

Who is affected by the new obligation?

By 31 March 2018, taxpayers:

  • with revenues or expenses exceeding EUR 10 million, or
  • holding shares in a company which is not a legal person and, in the preceding year generated revenues or incurred expenses exceeding EUR 10 million,

shall develop an analysis of comparative data for transactions concluded with affiliated entities.

In accordance with the new regulations, analyses of comparative data shall be primarily based on comparative data from the Polish market. 

Due to the nature of transactions concluded, the procedure of comparative data analysis is usually very comprehensive and includes acquisition of restricted financial data relating to similar transactions and statistical processing of such data.

Due to the highly specific nature of analyzed activity, the results achieved are often subject to comparability adjustments such as corrections arising from various level of risks assumed or assets employed by the parties to transaction.


O&W Analytics is a team of specialists with broad knowledge and experience in the field of finance, statistics and banking.

The team consists of analysts with professional experience in financial institutions, banks, consulting companies, graduates of reputable economic and technical universities.
