The Netherlands is implementing a major overhaul of its investment taxation system, with a new law set to take effect on January 1, 2028, that will tax unrealized capital gains on assets including Bitcoin, other cryptocurrencies, stocks, and bonds. The legislation, known as Wet werkelijk rendement Box 3, was approved by the Dutch parliament and marks a significant shift from the previous model.
Under the new system, investors will be taxed annually based on the actual change in value of their assets, regardless of whether they have been sold. The tax will be calculated by comparing an asset's value at the start and end of each calendar year, plus any income earned during that period. A flat tax rate of 36% will apply to positive net returns above an annual threshold of €1,800 per person. Losses incurred can be carried forward to offset future gains.
The reform, spearheaded by Deputy Finance Minister Tjebbe van Oostenbruggen, follows a court ruling that deemed the old Box 3 system—which taxed investors based on assumed returns—unfair. Lawmakers argue the new approach is more accurate and treats all asset classes equally, creating fairness by taxing real gains instead of estimates.
However, the proposal has sparked significant concern within the investment community, particularly for crypto holders. Critics warn that taxing paper gains could create liquidity pressure, forcing investors to sell assets simply to cover tax liabilities. There are also fears that the change could drive crypto investors and businesses to relocate from the Netherlands. The enforcement method is projected to involve data-sharing with financial platforms, similar to current practices with banks.
Market experts are closely watching the initiative, noting it is uncommon on an international scale and could make the Netherlands a case study for capital growth taxation. The effects on digital asset values and market liquidity remain under scrutiny as the 2028 implementation date approaches.
