Netherlands drops unrealized BTC gains tax plan

TLDR

The Dutch government has backed away from taxing unrealized Bitcoin gains, shifting its Box 3 reform toward taxing gains when they are actually realized.

1. The original Box 3 plan would have taxed annual paper gains on liquid assets like Bitcoin at 36 percent, but that unrealized gains approach is now being dropped.
2. For now crypto stays in the existing wealth tax system, and current proposals only move direct crypto holdings to a realized-gains regime around 2030.
3. The reform is still a proposal that parliament must approve, so rates, thresholds and the exact crypto treatment could change further.

Deep Dive

1. Unrealized BTC Tax Plan Scrapped

Earlier this year, the Netherlands Actual Return in Box 3 Act would have taxed actual annual returns on liquid assets, including value changes that existed only on paper. That meant Bitcoin (BTC) holders could face a 36 percent tax on yearly price appreciation even if they did not sell.

In a letter dated 29 September, Prime Minister Rob Jetten and Finance Minister Eelco Heinen instead proposed taxing investment gains only upon realization, starting in 2028, abandoning the plan to tax unrealized appreciation on liquid assets such as Bitcoin, after significant investor backlash and liquidity concerns. This shift is described in reports on the revised Box 3 plan and the governments letter to parliament, which note that unrealized gains taxation is being dropped for most investments.

2. How Crypto Is Taxed Now And Under The New Plan

Today, crypto sits in Box 3 as part of the Dutch wealth tax. For 2026, crypto holders face a deemed return of about 6 percent on Box 3 assets, taxed at 36 percent, effectively a wealth tax on the portfolio value rather than a realized capital gains tax.

Tax specialists cited in a community analysis explain that under the revised proposal roughly 90 percent of Box 3 assets would move to a capital gains style system in 2028, with direct crypto holdings and some other assets only switching to realized-gains taxation in 2030. That means crypto could still be subject to annual value-based taxation in 2028 and 2029, even as shares and bonds move earlier to realized gains.

Separately, EU DAC8 rules already require Dutch-facing crypto service providers to report customer IDs and transaction data, increasing enforcement capacity even if the tax base changes.

3. Political Process And Key Things To Watch

The revised Box 3 plan is not yet law. Jettens three party coalition lacks a parliamentary majority, so the government needs opposition votes in both chambers to pass the overhaul. That creates room for amendments, including to cryptos timeline.

The Finance Ministry estimates the shift away from the original unrealized gains design will cut revenue by about 15 billion through 2035, and plans to offset part of this by lowering the planned 2028 tax free return from 1,800 to 1,000. That could draw more smaller investors, including some crypto holders, into Box 3.

For crypto users, the key signals are parliaments treatment of direct holdings, any special rules for volatile assets, and the final dates when crypto moves from wealth style taxation to realized capital gains.

Conclusion

Dropping the plan to tax unrealized Bitcoin gains is a clear positive for the Dutch investment climate, reducing the risk of forced selling just to pay tax on paper profits. However, crypto remains fully within Box 3, with a complex transition ahead and a possible lag before it enjoys the same realized gains treatment as traditional securities. Dutch BTC holders should focus on how parliament finalizes Box 3, especially the timing and structure of crypto specific rules, rather than assuming the tax debate is over.
