The Dutch government presented a new bill to the Parliament aimed at reforming the taxation system for income derived from assets, known as the ‘Actual Return on Investment in Box 3 Act.’ The bill regarding Box 3 introduces two main categories of taxation: capital growth tax and capital gains tax. Given recent changes to Dutch tax law, all individuals under the 30% ruling will lose their near-total exemption from taxes on substantial shareholdings (Box 2) and savings and investments (Box 3). If such individuals are Dutch tax residents, the changes to Box 3 under this bill will apply to them as well.
