Netherlands drops unrealized BTC gains tax plan

TLDR

The Dutch government has backed away from taxing unrealized Bitcoin and other investment gains, and is pivoting toward taxing gains only when they are actually realized.

1. The earlier Box 3 reform would have taxed annual unrealized gains on liquid assets like Bitcoin at 36 percent, but that plan is now being dropped after criticism.
2. A new proposal suggests realized gains taxation from 2028 for most financial instruments, with direct crypto likely moving to the same regime in 2030, subject to parliament approval.
3. For now, Dutch crypto holders stay under the existing Box 3 deemed return rules, while they should watch upcoming legislative debates and possible changes to tax-free allowances.

Deep Dive

1. From Unrealized To Realized Gains

Earlier Box 3 legislation, the Actual Return in Box 3 Act, had already passed the lower house and would have taxed annual appreciation on liquid assets, including Bitcoin, at 36 percent even if investors did not sell, raising liquidity and forced-sale concerns in volatile markets. That approach has now been abandoned, with the government explicitly stating in a September 29 letter that unrealized gains will not be taxed and that investment gains should instead be taxed only upon realization, starting in 2028 for most assets. This shift responds to strong investor and business backlash and aims to avoid taxes on paper profits that might later disappear.

2. What It Means For Dutch Crypto Holders

Under the current system, crypto in Box 3 is taxed using a deemed return, for example a 6.00 percent assumed annual return taxed at 36 percent in 2026, rather than actual price changes. The revised plan would move shares, bonds and similar instruments to a realized-gains system in 2028, while direct crypto holdings and some other Box 3 assets are expected to remain under annual value-change taxation in 2028 and 2029, then join realized-gains taxation in 2030 according to cabinet proposals. At the same time, the government is considering lowering the tax-free allowance to help offset an estimated 15 billion euro revenue shortfall, which could pull more small investors into Box 3.

3. Next Steps And Remaining Uncertainty

The new approach is a proposal, not yet law. The cabinet lacks a majority and needs support from opposition parties in both chambers, so terms, timelines and thresholds can still change in negotiations. There is also ongoing debate over whether crypto will follow exactly the same timetable as other financial instruments or see distinct rules. In parallel, EU reporting rules already require Dutch crypto service providers to share transaction data with tax authorities, so enforcement of whatever regime is adopted is likely to be robust.

Conclusion

Dropping the unrealized-gains tax plan removes a major immediate threat to Dutch Bitcoin and crypto investors, replacing it with a more conventional focus on realized gains. However, Box 3 reforms still aim to raise revenue from investment returns, and details on timing, allowances and crypto-specific treatment remain open. For crypto users in the Netherlands, the key is to track how parliament reshapes Box 3 and when crypto is formally shifted into a realized-gains framework.
