Key Takeaways
- The Netherlands plans to replace its current Box 3 system with a system that taxes largely on actual investment returns from January 1, 2028.
- Under the legislation passed by the lower house, annual appreciation of assets, including crypto, would generally be included in taxable income even when investors have not sold.
- The proposed 36% rate applies to investment returns, not the total value of crypto or gold holdings. The bill remains under consideration in the Dutch Senate, and the government is considering further changes.
Dutch investors could eventually face annual tax bills on crypto and investment-gold gains they have never cashed out, under a major overhaul of the country’s Box 3 wealth tax regime.
The proposed Wet werkelijk rendement box 3, or Actual Return Box 3 Act, was approved by the Dutch House of Representatives on Feb. 12 and is now before the Senate. The government is targeting Jan. 1, 2028, for implementation.
The 36% figure needs context: investors would not lose 36% of their Bitcoin or gold every year. Instead, the rate would apply to taxable investment returns, including qualifying annual increases in asset values.
Crypto Gains Could Be Taxed Before Sale
The proposed system moves away from taxing investors primarily using assumed returns.
As a general rule, Box 3 would use a capital-accrual tax that incorporates both income, such as interest and dividends, and annual increases or decreases in asset values.
Real estate and qualifying startup shares are treated differently, with capital gains generally taxed upon realization.
Crypto falls on the other side.
Dutch tax authorities already define actual returns as including changes in cryptocurrency values, and parliamentary debate over the new system specifically addressed crypto’s volatility.
Consider an investor whose crypto portfolio rises from €100,000 to €150,000 over the course of a year. Ignoring allowances, losses and other adjustments, a €50,000 taxable gain at a 36% rate would imply €18,000 in tax, even if the investor had not sold the crypto.
Physical Gold Could Face Similar Treatment
Investment gold could also fall within the broader annual-accrual framework.
The Dutch tax authority has confirmed that gold coins held as investments belong to Box 3’s “other assets” category rather than being treated as cash. Parliamentary debate on the new legislation also explicitly discussed gold alongside other assets.
That potentially creates the same liquidity problem facing crypto holders: an asset can appreciate without producing cash with which to pay the resulting tax.
The government is already considering modifications to the legislation, including changes addressing some consequences of annual capital-accrual taxation.
100% Crypto Rally Could Create a Large Tax Bill
Crypto’s volatility makes the proposal particularly consequential.
A Bitcoin holder could record a substantial taxable gain during a bull market, pay tax based on that year’s appreciation, and then watch the asset fall sharply afterward.
Loss treatment therefore becomes crucial. The legislation provides for losses under the new system to be carried forward against future Box 3 income, while the government has also been examining whether limited backward loss relief should be introduced from 2029.
The 2028 framework is not yet final. But if implemented broadly as proposed, Dutch crypto and gold investors would need to consider more than just what they eventually make when they sell.
They may also need enough cash each year to pay tax on gains that still exist only on paper.
