The Dutch government has announced plans to amend its recently approved wealth tax legislation, which included taxing unrealized gains, due to significant public criticism. Finance Minister Eelco Heinen stated the legislation "cannot proceed as it is" and that "something simply went wrong." The proposed tax, which would have levied a 36% capital gains tax, faced backlash for potentially stifling entrepreneurship.
The new Dutch government has decided to postpone the implementation of the Box 3 tax system, originally scheduled for 2028. This decision comes amid significant criticism regarding the taxation of unrealized gains, which would have required investors to pay taxes on assets that have increased in value but have not yet been sold. The Minister of Finance intends to amend the bill.

This significant legislative development is set to take effect on January 1, 2028, replacing the previous unconstitutional system based on assumed returns. The government anticipates this reform will generate substantial revenue, despite criticism.
The new Dutch coalition government plans to overhaul the Box 3 wealth tax system, intending to eliminate the annual tax on unrealized gains and instead tax investors only when assets are sold at a profit. This marks a significant policy shift from previous plans.
