The Incomes Register contains information on individuals' wages, pensions, and benefits. Employers are required to report salaries and other relevant information to the Incomes Register. Unemployment funds receive information of wages, pensions, and benefits from the Incomes Register. The information is retrieved for the Incomes Register when your application has arrived at the fund.
Regardless of the Incomes Register, you must always inform the unemployment fund yourself about your work and income during the application period (e.g. in your daily allowance application).
