The Netherlands is planning to introduce a major tax overhaul by 2028 that would require investors to pay taxes on the increased value of their assets, even if they have not sold them.
Key Takeaways
- The Dutch government is proposing a tax on unrealized gains from assets like Bitcoin, stocks, and bonds starting in 2028.
- Investors would be taxed annually based on the increase in value of their holdings at the end of each year, regardless of actual sales.
- Critics warn of liquidity issues and capital flight, while supporters say it promotes fairness and improves revenue collection.
- If enacted, the Netherlands would become one of the few countries taxing unrealized gains, marking a significant shift in global tax policy.
What Happened?
The Dutch parliament is considering a landmark proposal to tax unrealized gains from investment assets, including Bitcoin, stocks, and bonds, beginning in 2028. This change would make the Netherlands one of the first countries to impose such a tax. The proposed reform aims to tackle wealth inequality and modernize how investment income is taxed in a rapidly evolving digital economy.

Dutch Parliament Advances Major Tax Reform
The proposal is part of a wider tax reform currently debated in the Dutch House of Representatives (Tweede Kamer). It would replace the current ‘Box 3’ tax regime, which taxes assumed returns on savings and investments, with a model based on actual asset appreciation.
Under the new plan:
- Investors would be taxed yearly based on the value of their assets at the start and end of each calendar year.
- This includes cryptocurrencies like Bitcoin, traditional stocks, bonds, and possibly other digital assets.
- The reform is expected to receive majority support in parliament, according to Dutch media reports.
Rising Debate Over Fairness and Feasibility
The proposed tax has sparked heated debate within the financial and investment communities.
Supporters argue that taxing unrealized gains helps close tax loopholes for wealthy investors who accumulate significant paper profits without selling. They also believe it could boost public revenue and make the tax system more equitable.
However, critics are raising red flags about several potential downsides:
- Investors may face liquidity problems, being forced to pay taxes on gains they haven’t converted into cash.
- Asset valuation is complicated, especially for digital assets like NFTs and DeFi tokens that lack consistent pricing.
- The reform could lead to capital flight, with investors and firms moving to countries with more favorable tax laws.
A Break from Global Norms
Most major economies, including the United States, United Kingdom, Germany, and Portugal, only tax capital gains when assets are sold. The Dutch proposal puts the country on a unique path. Some countries like the U.S. have floated similar ideas, such as a “mark-to-market” tax for the ultra-wealthy, but none have implemented it at this scale.
Here’s a quick comparison:
| Country | Tax on Crypto Gains | Tax on Unrealized Gains? |
|---|---|---|
| United States | On sale | No |
| United Kingdom | On disposal | No |
| Germany | Tax-free after 1 year | No |
| Portugal | Generally tax-free | No |
| Netherlands | Proposed annually from 2028 | Yes |
What It Means for Investors?
If the law is passed, both crypto and traditional investors in the Netherlands will need to prepare for a new financial landscape.
Key Implications:
- Meticulous record-keeping will be essential to track end-of-year values across all assets.
- Investors will need to manage cash flow proactively to cover annual tax bills, even without selling.
- The reform may discourage long-term holding strategies in favor of more active portfolio management.
For crypto users in particular, the volatility of digital assets like Bitcoin could create unpredictable tax obligations. Without careful planning, investors might be taxed on gains that disappear the next year due to market swings.
CoinLaw’s Takeaway
Honestly, I think this is one of the most ambitious tax proposals we’ve seen in recent years. In my experience, taxing unrealized gains is incredibly tricky. On paper, it sounds fairer, but in practice it could backfire. For crypto investors, it adds a huge layer of complexity and risk. I found the liquidity issue especially worrying. Imagine being forced to sell part of your Bitcoin just to pay taxes on a gain you never locked in. That could hurt long-term strategies and even destabilize markets. If this passes, it could trigger a chain reaction across Europe. We need to watch this one closely.
