The Netherlands may begin taxing capital gains on assets including cryptocurrencies annually starting in 2028, regardless of whether the investment has been realized.

The Dutch House of Representatives recently debated a proposed amendment to the Box 3 tax system. The proposal suggests taxing capital gains (including realized and unrealized gains) on assets such as stocks, bonds, and cryptocurrencies annually, starting in 2028. While most members of parliament believe the plan has flaws and that taxing unrealized gains is undesirable, the proposal is expected to receive majority support due to the estimated €2.3 billion annual loss to the national treasury from delayed implementation.
