Netherlands Moves to Tax Unrealized Crypto and Stock Gains from 2028
Parliament in the Netherlands is poised to approve controversial changes to Box 3 that will subject unrealized gains on assets — including cryptocurrencies such as Bitcoin (BTC) and publicly traded stocks — to taxation beginning in 2028. Lawmakers argue the reform closes perceived loopholes in wealth taxation, but critics and many investors warn the measure is punitive and will complicate wealth management and reporting.
The decision matters because taxing unrealized gains can create liquidity stress (forcing sales to pay tax), add compliance burdens for exchanges and custodians, and prompt some taxpayers to consider relocation or restructuring. The 2028 start gives market participants time to adapt, but uncertainty about valuation rules and cross-border implications has already soured sentiment among investors and industry groups.
