Information regarding corporate income taxation for tax year 2022 will be released on 8 November 2023.

In the taxation of corporate entities and benefits under joint administration, the public information consists of:

  • Taxpayer’s name, municipality of corporate domicile, Business ID, and in the case of a non-resident death estate, the deceased person’s year of birth
  • Taxable income
  • Total of tax imposed
  • The total amount of taxes pre-paid by/withheld from the taxpayer
  • The taxpayer’s balance of back taxes or tax refund

The list of facts and information is from the day when the tax assessment process was completed. Any later adjustments made due to appeal are currently not subject to public disclosure.

The changes made to corporate income taxation after the completion of tax assessment will also be public as of tax year 2022. Amended tax information regarding tax year 2022 will be published in September 2024. In future, amended tax information will be published after the 20th day of the month following the month in which the change was made.
