In Box 3, assets are subdivided into three categories: cash and bank balances, other assets, and debts. The return on other assets is assessed on the basis of long-term average returns on securities, bonds and property. As from 2026, rental income or, as the case may be, an owner-occupied property is taken into account as well. This results in a fixed return on the other assets of 7.78%. Since the return on bank balances and debts is based on current interest rates, its final assessment is not possible until after the end of the year. Hence, the percentages listed for those categories are provisional in 2025.
