Frequently asked questions
In the Netherlands, crypto counts as an asset in box 3. In your tax return you report its value on 1 January at 00:00, at the price on the platform you use. This calculator works that out per coin.
Which price should I use?
The Dutch Tax Administration asks for the price on the exchange platform you use. If your coins were on Bitvavo, you take the Bitvavo price. That is why we show the price on six platforms side by side.
Which moment counts?
1 January at 00:00 Dutch time (CET). Exchanges work in UTC, where that moment is 31 December 23:00 UTC. We use the opening price of that hour.
My crypto is on several platforms. How do I calculate that?
Value each coin at the price on the platform where it was held and add everything up. In the calculator you choose the platform per coin, so the same coin can appear twice.
What about crypto in my own wallet?
The Dutch Tax Administration does not name a fixed source for that. Choose a reliable price, for example from the platform where you bought the coins, and use the same source and moment every year.
Do I have to pay tax on it?
Not always. Your crypto is added to your other box 3 assets, such as savings and investments, and the tax-free allowance is applied automatically. You only pay tax above it.
What if my actual return was lower?
Then you may report your actual return. You need the value on 1 January and on 31 December, plus your purchases and sales over the year. The value on 31 December is practically the same as on 1 January of the next year, which you can also find here.
Do you store my data?
No. Your coins and amounts stay in your browser and are never sent to our server. You need no account and we set no cookies.
