Tax­onomies for fi­nan­cial state­ments

Taxonomies are descriptions of data contents. They enable data content of a report to be presented in a structured and consistent format. A taxonomy must be used in order to output digital financial statements. Taxonomies alone do not produce information, increase the amount of information, or guarantee its quality.

The taxonomy defines the data elements to be reported and their interrelations. This means that the taxonomy consists of basic elements and the Linkbase definitions that define the dependencies, description logics, terminologies and calculation rules between these elements.

The PRH is responsible for developing the reporting of digital financial statements and, with respect to the SBR taxonomy, for maintaining the sections intended for the financial reporting of companies.

You can take part in the development work by participating in the working group that develops and maintains taxonomies for financial statements. Read more about the working group.​

XBRL taxonomy

The XBRL taxonomy is a description of the data content in a report in the XBRL language.

The XBRL taxonomy is presented as a group of XML schema files with related XML metadata libraries produced in accordance with the XBRL specification. These are used to define the data content that describes a certain reporting set in a machine-readable format. The metadata libraries can be used to define, for example, titles, presentation format and calculation formulas for the data content that is collected. The data content that is reported against the taxonomy can also be validated.

The taxonomy is based on the XBRL basic standard administered by XBRL International.

SBR taxonomy

The SBR taxonomy is developed for producing financial reporting in accordance with the Finnish accounting legislation. The SBR taxonomy comprises reporting sets for financial statement reporting as well as for the financial reporting of municipalities and wellbeing services counties. The reporting sets for financial statement reporting are maintained and developed by the PRH. The reporting sets for the financial reporting of municipalities and wellbeing services counties are maintained and developed by the State Treasury.

The SBR taxonomy is utilised in companies’ financial statement reporting when structuring financial statements prepared in accordance with the FAS. At the moment, the latest version of the SBR taxonomy includes the following entities for financial statement reporting:

  • OYTP (Financial statement reporting of limited liability companies and co-operatives)
  • LSTP (Financial statement reporting of credit institutions and investment service firms)
  • VYTP (Financial statement reporting of insurance companies)
  • STP (Financial statements of foundations)
  • STK (Annual report of foundations)


The SBR taxonomy and its updates will be published on the avoindata.fiAvautuu uuteen välilehteen platform as “SBR taxonomy information material”. The publications include the taxonomy and supporting instructions for applying it. In addition, versions of the SBR taxonomy related to the reporting sets of municipalities and wellbeing services counties will be published as separate datasets.Avautuu uuteen välilehteen​

PRH to update the taxonomy specifications annually

The PRH will annually approve the sections of the SBR taxonomy specifications concerning companies’ financial reporting before the end of the year so that the approved taxonomy specification is available for financial periods starting from the beginning of the following year. For instance, the taxonomy specification approved at the end of 2025 must be used for financial periods starting on or after 1 January 2026.

The annual update will incorporate any legal amendments and other necessary updates arising during the year. However, the basic structure of the specifications will not change. The company’s reports must always follow the latest taxonomy specification, but it can use the previous year’s reporting template to prepare its financial statements.

Adoption of prh identifiers

The PRH has issued a decision on the use of PRH identifiers, which is a taxonomy specification approved by the PRH. Accordingly, a company subject to sustainability reporting must file financial statement documents marked up with PRH identifiers for financial periods starting on or after 1 January 2026.

ESEF taxonomy

The ESEF taxonomy is a taxonomy definition developed and maintained by the European Securities and Markets Authority (ESMA). The deployment of the taxonomy is regulated according to the delegated regulation on ESEF (ESEF RTS) adopted in the EU. Read more in the annually updated delegated regulation on ESEF RTS on the EurLex websiteAvautuu uuteen välilehteen.

The ESEF financial statements must be sent to the Official Appointed Mechanism of Nasdaq HelsinkiAvautuu uuteen välilehteen and, as of the financial period starting in 2024, also to the Finnish Trade Register. Read our instructions: Digital financial statements of limited liability companies.

IFRS taxonomy

The IFRS taxonomy is a taxonomy specification maintained by the IFRS Foundation. It complies with the presentation and publication requirements for financial statements prepared in accordance with the IFRS. The IFRS taxonomy is updated as new and updated IFRS accounting standards are published. The IFRS taxonomy can be applied as its own taxonomy, but it is also used as the basis for other taxonomies such as ESEF.

The PRH advises applying the IFRS taxonomy for marking up financial statements if the financial statements have been drawn up in accordance with the IFRS. If the consolidated financial statements have been drawn up in compliance with the IFRS and the parent company’s financial statements have been drawn up in compliance with the FAS, the consolidated financial statements should be marked up according to the IFRS taxonomy, and the parent company’s financial statements according to the SBR taxonomy.

The versions of the IFRS taxonomy are available on the IFRS Foundation’s website.Avautuu uuteen välilehteen In addition, you can check here which versions of the IFRS taxonomy are currently supported in the PRH’s receiving interface.

The IFRS Foundation provides instructions and material to help use the application and the IFRS taxonomy. The instructions are available on the IFRS Foundation’s website.Avautuu uuteen välilehteen​
