The calculation of the “Deel hypotheekschuld naar box 3” is incorrect in the income tax return if an amount is filled in at 'Aflossing in 202x op de eigenwoningschuld'. The outcome may differ from what you expected. This applies to the years 2023 and 2024. We are investigating the issue and will update this page as soon as more information becomes available. Our apologies for the inconvenience.
