Netherlands plans 36% crypto gains tax

TLDR

The Netherlands is considering a 36% tax on investment returns, including unrealized crypto gains, from 2028, but this is a proposal, not law yet.

1. A bill would tax actual returns on assets like crypto, stocks, and bonds at about 36% and include unrealized gains above roughly 1,800 per person.
2. For crypto holders, taxing unrealized gains creates cash flow and valuation challenges, especially given high volatility and assets held across different platforms.
3. The key variables to watch are if Parliament approves the bill, how unrealized gains are calculated in practice, and whether other EU countries copy or reject this approach.

Deep Dive

1. What The Proposal Actually Does

Dutch policymakers have put forward a bill that shifts the current Box 3 wealth tax toward actual returns on investments, with a proposed rate around 36% that would apply to cryptocurrencies, stocks, and bonds.

According to a summary of the bill, it would apply from 2028 and explicitly target unrealized gains above a per-person threshold of about 1,800 each year, making the Netherlands a rare case of taxing capital growth before it is realized.

Enforcement is expected to rely heavily on data sharing between financial institutions, investment platforms, and tax authorities, similar to existing banking reporting, which would likely include centralized crypto platforms that serve Dutch residents.

2. Why This Matters For Crypto Users

For crypto investors, taxing unrealized gains is especially sensitive because crypto prices can swing widely after the tax date, leaving people paying tax on gains that may later disappear.

If the rate and design are adopted as described, some investors could need to sell assets just to fund their tax bill, which might increase forced selling around tax dates and add to volatility.

The annual valuation requirement also raises practical issues, such as which prices and exchanges are used for official tax values and how to handle assets on smaller or foreign platforms.

3. What To Watch Next

Parliament still needs to debate and vote on the bill, and details can change, including the 36% rate, the 1,800 allowance, and how unrealized returns are computed across different asset classes.

There is already debate about whether such a system might hurt the Netherlands attractiveness for investors and founders, especially in digital assets, which could influence amendments or potential carve-outs.

Other European countries are watching this as a test case; a smooth rollout could inspire copycat policies, while strong backlash or implementation problems could make it a cautionary tale instead.

Conclusion

The Dutch plan to tax actual investment returns, including unrealized crypto gains, would be a major shift in how digital assets are treated for tax purposes, but it is not final yet. How Parliament adjusts or approves the proposal, and how valuation and reporting rules are implemented, will determine whether the Netherlands becomes a tougher or simply more formalized jurisdiction for long term crypto investing.
