Netherlands drops unrealized Bitcoin gains tax plan

TLDR

The Dutch government has reversed course and now proposes taxing Bitcoin and other investments only on realized gains, not unrealized gains, from 2028.

1. The earlier Box 3 reform that could have taxed annual unrealized gains at 36 percent on Bitcoin and other assets has been dropped after investor backlash.
2. The new plan shifts most investments to a realized gains system from 2028, with direct crypto likely moving to the same treatment from 2030, but details are still being debated.
3. The proposal is not yet law and could change as it moves through parliament, including possible adjustments to tax free allowances that would affect smaller investors.

Deep Dive

1. What Was Dropped

Earlier this year, the Netherlands advanced the Actual Return Box 3 Act, which would tax annual investment returns, including unrealized price gains, at 36 percent for assets such as Bitcoin and investment gold. That bill passed the lower house and was before the Senate, raising the prospect of yearly tax bills on paper gains.

In a letter dated 29 September 2026, Prime Minister Rob Jetten and Finance Minister Eelco Heinen instead proposed taxing investment gains only when they are realized through a sale starting in 2028, abandoning the unrealized gains approach for most liquid assets, including Bitcoin. This shift is framed as a response to concerns about liquidity and forced selling in volatile markets, and as a way to support the Dutch investment climate without punishing unrealized appreciation.

2. How It Hits Bitcoin And Crypto Holders

Under current Box 3 rules, crypto is treated as wealth taxed on a deemed return. For 2026, that deemed return is 6.00 percent, taxed at 36 percent, rather than on actual price moves.

The revised plan would gradually move Box 3 toward real capital gains taxation. Most financial instruments like shares and bonds would be taxed on realized gains from 2028. According to tax specialists cited in a CoinsKid community report, roughly 90 percent of Box 3 assets exposed to price movements would fall into this realized gain bucket at that point. Direct crypto holdings would still face annual taxation on value changes in 2028 and 2029, then shift to realized gains taxation in 2030 under the current proposal.

The government estimates the change will reduce revenue by about 15 billion euros through 2035 and is considering lowering the tax free allowance, for example from 1,800 euros to 1,000 euros, which could bring more small investors into Box 3 tax.

3. What To Watch Next

The revised Box 3 plan is not yet law. Jettens three party coalition does not have a majority in parliament, so it must secure opposition support in both chambers to pass the overhaul. Ongoing discussions may also clarify whether crypto follows the same timeline as other financial instruments or gets a distinct path.

Investors should watch for three things: parliamentary votes on the revised Box 3 framework, changes to the tax free allowance that affect whether smaller holdings are taxed, and any specific guidance on how direct crypto holdings transition from deemed returns to realized gains treatment around 2028 to 2030.

Conclusion

The Netherlands has stepped back from taxing unrealized Bitcoin gains annually and is steering Box 3 toward a more conventional capital gains model that taxes realized profits instead. For crypto holders, that removes the most punitive part of the earlier plan but does not eliminate Box 3 taxation or future changes to thresholds and timing. The key next signals will be parliamentary decisions and detailed rules on when and how crypto moves fully onto a realized gains basis.
