For crypto holders, this change is revolutionary—and potentially costly. Unlike the current system, the new rules will target unrealized capital gains, meaning you could owe taxes on the value increase of your $Bitcoin even if you haven’t sold a single satoshi.
How the New Capital Growth Tax Works
The core of the 2028 reform is the transition from “deemed” returns to actual returns. Under the proposed “capital growth” model, the Dutch tax authorities (Belastingdienst) will look at your total wealth at the beginning and end of each year.
Taxing the “Paper” Gains
If you hold $Ethereum or other digital assets, the government will calculate the difference in market value between January 1st and December 31st.
- Price Increase: If your portfolio grew by €10,000, that entire amount is considered taxable income for that year, even if the coins are still in your hardware wallet.
- Staking & Yield: Direct income, such as staking rewards or interest from lending, will also be taxed as part of the actual return.
The 36% Tax Rate
The current proposal suggests a flat tax rate of 36% on these actual returns. However, there is a small “tax-free” threshold planned, expected to be around €1,800 per person on the total return, rather than a threshold on the total asset value.
Crypto Platforms and DAC8 Compliance
To ensure nobody “forgets” to report their holdings, the Netherlands is already implementing the European DAC8 Directive as of 2026. This mandate requires crypto exchanges and service providers to automatically share user data with tax authorities.
By 2028, the Belastingdienst will receive data on your holdings directly from platforms. This makes it essential for investors to keep accurate records. Using professional crypto tax software can help you track these unrealized gains and losses automatically, ensuring you don’t get hit with unexpected penalties.
The “Real Estate” Exception
Interestingly, not all assets are treated equally. While crypto, stocks, and bonds will face taxes on unrealized gains, real estate (other than your primary residence) will follow a capital gains model. This means property investors will only pay tax on value increases when they actually sell the property, though rental income will still be taxed annually.
What Happens if the Market Crashes?
A major concern for traders is what happens during a “crypto winter.” If the value of your assets drops, the new system allows for loss compensation.
- Offsetting: You can use losses to offset gains in the same year.
- Carry Forward: If you have a net loss, you can carry it forward indefinitely to future years to reduce your taxable income when the market recovers.
As reported by major authorities like Deloitte, while the plan is controversial due to potential “liquidity issues” (taxpayers needing to sell assets to pay the tax), the government is moving forward to comply with Supreme Court mandates.
