Netherlands unrealized gains tax on stocks and crypto fuels capital flight concerns

On a proposal debated in the Dutch parliament, lawmakers appear poised to overhaul the Box 3 asset tax by imposing annual levies on both realized and unrealized gains for assets such as stocks, bonds and cryptocurrencies. Officials argue the change is needed to address court rulings and prevent an estimated 2.3 billion euros in lost yearly revenue, while critics from the investment and crypto communities warn it could drive capital and talent out of the Netherlands.
