The Netherlands is moving closer to a new tax plan on investment gains. The proposal targets stocks, bonds, and crypto assets even when they are not sold.
Reports state the Netherlands lower house approved the Box 3 Actual Return Act on February 12, 2026. The bill proposes a 36 percent tax on annual gains, including unrealized profits, but it is not final law. The proposal has drawn attention across financial markets and digital asset communities in Europe.
Netherlands Parliament Moves Forward With Box 3 Tax Plan
Lawmakers in the lower house supported the Box 3 Actual Return Act. The proposal sets a flat 36% tax rate on yearly gains from assets. It includes stocks, bonds, and crypto holdings. The tax applies even if assets are not sold. The measure is not yet enforceable law, it still requires approval from the Senate.
Based on Crypto Patel, Finance officials are also reviewing changes due to concerns about rejection risk. The proposal aims to replace a system ruled illegal by the Supreme Court. The Box 3 system was previously based on assumed returns rather than actual gains. The Supreme Court ruled parts of the old system incompatible with tax law.
This ruling pushed lawmakers to design a new annual return based model. Senate review is expected to focus on fairness and economic effects. Some members have raised concerns about taxing unrealized gains annually. Adjustments may be introduced before final voting in the upper chamber.
Tax Rules, Allowance, and Possible Start Date
The draft includes a yearly tax-free allowance of €1,800. Losses may be carried forward to future years. Real estate and startup shares are taxed only upon sale. These rules aim to adjust how different assets are treated. The earliest possible start date is January 1, 2028. Officials say no tax is owed on unrealized gains today.
The analyst stated, “It is not law yet and still needs Senate approval.” The timeline depends on final parliamentary approval.
The €1,800 allowance applies per individual taxpayer each year. It reduces the taxable base before applying the 36% rate. Different asset categories may have separate treatment under draft rules. Crypto assets fall under the same annual assessment framework. If approved, implementation would start after final legislative clearance.
Authorities have not confirmed further changes to tax percentages. The proposal continues to be discussed between lower and upper houses. Market participants are watching Senate discussions closely as revisions may change final wording. The proposal remains subject to political negotiation before any enforcement timeline is set. Final approval is required before taxation changes take effect across Netherlands investment assets framework rules.
