The introduction of a new tax system in box 3 (tax on savings and investments) will be delayed by another year according to State Secretary Marnix van Rij. The previously planned introduction date of the new system on 1 January 2026 has turned out to be unfeasible and is now set for 1 January 2027.
According to the Dutch Supreme Court (ECLI:NL:HR:2021:1963), the tax system of box 3 levy must be based on the actual return achieved on savings and investments instead of deemed income. The Dutch government is struggling with this due to amongst others budgetary effects. Another reason for the postponement is the delay in the modernizing of the required ICT infrastructure at the Dutch Tax and Customs Administration. Currently it is unclear whether a new mass objection procedure will be initiated against the recently introduced savings variant levy in box 3 (also on a deemed income basis). Therefore, it is- in order to retain rights- necessary to take further action yourself, if the actual return on your savings and investments is lower than that which is currently taken into account in imposed tax assessments and tax returns.
