The Tax Administration's Incomes Register Unit is a controller for the Incomes Information System as referred to in the European Union’s General Data Protection Regulation (EU 679/2016).

The Incomes Information System

The Incomes Information System consists of two parts

  • the Incomes Register, which contains information submitted to meet the statutory reporting and disclosure obligation and information disclosed in compliance with the data access right, as well as
  • a register containing identifying and contact information used for data verification and validation purposes.

In everyday language, the term "Incomes Register" is often used instead of "Incomes Information System."

The Incomes Information System is used to receive and store data reported by employers and other parties referred to in the Act and forward the data to authorities and other parties entitled to such data in order to fulfil the payers’ statutory reporting and disclosure obligation as well as to implement data access rights.
