Netherlands Proposes New Tax Framework for Bitcoin and Crypto Gains by 2028

The Dutch government is advancing a tax reform that could include unrealized gains from assets like Bitcoin (BTC) in fiscal calculations starting January 1, 2028. The proposed model aims to replace the current 'Box 3' system with one based on actual asset performance, taxing value increases even if the asset has not been sold. While the proposal mentions Bitcoin and stocks as examples of assets subject to this indirect return tax, specific rates and valuation mechanisms remain undefined. The plan allows for loss compensation in future years and distinguishes between liquid assets and others like real estate or startup shares, which would be taxed upon realization. The bill passed the Second Chamber in February 2026 and is currently under review in the First Chamber.
