Large international companies required to file reports on income tax information with the Finnish Trade Register
In future, large companies operating in several countries must draw up and file a report on income tax information with the Finnish Trade Register. A report on income tax information is a separate report from the financial statements and the annual report. The report gives an account of the income taxes the company has paid in countries other than Finland.
The report on income tax information must be drawn up as of financial periods starting on or after 22 June 2024 and filed with the Finnish Trade Register within 12 months of the end of the financial period. The company must also publish the report on income tax information on its website and keep it available for at least five years.
The purpose of public access to the report on income tax information is to promote the idea that the company pays income taxes in the country where it makes a profit. Public access allows people to assess companies’ businesses based on tax information.
The requirement to draw up and file the report on income tax information is based on the Finnish Accounting Act.
The obligation applies to large international companies
The obligation to draw up and file a report on income tax information applies to the following companies operating in several countries:
- Companies and ultimate parent companies whose turnover is over 750 million euros during both the concluded financial period and the one preceding it.
- Large and medium-sized companies that are ultimately controlled by a parent company outside the European Economic Area if the turnover of the parent company’s consolidated financial statements is over 750 million euros during both the concluded financial period and the one preceding it.
- A Finnish branch of a company outside the European Economic Area if its turnover or, if it is not a standalone company, the turnover of its ultimate parent company established outside the European Economic Area is over 750 million euros.
The report on income tax information does not need to be prepared and filed if the company operates solely in Finland.
Report on income tax information is drawn up in a structured format
The report on income tax information must be drawn up in a structured digital format when reporting on financial periods starting on or after 1 January 2025. Reporting must follow the tagging specifications of the iXBRL taxonomy and apply the taxonomy developed by the European Commission.
A report generator developed by the Commission can be used for converting the report on income tax information into a structured format.
The Commission’s taxonomy package and report generator are only available in English.
The report on income tax information can be drawn up in PDF format if it concerns financial periods starting between 22 June 2024 and 31 December 2024.
Further information on the report on income tax information and the companies obligated to report, as well as links to the Commission’s taxonomy and report generator, can be found at prh.fi.
