How we calculate
CryptoPeildatum calculates the value of your crypto on 1 January of a year you choose. This page explains which price we use and what to keep in mind.
Which price
We use the euro price on the platform you choose per coin, Bitvavo, Coinbase, Kraken, Binance, Bitstamp or Crypto.com, on 1 January at 00:00 CET, Dutch time. That is the moment the Dutch Tax Administration uses. Exchanges record prices in UTC, where this moment is 31 December 23:00 UTC. We take the opening price of that hour. If there was no trading in that hour, we use the last price before it, up to 24 hours back. Kraken publishes no historical hourly prices; there we use the first trade in that hour, or else the last earlier trade. We multiply that price by the amount you enter.
Why 1 January
In the Netherlands, the tax authorities look at what you owned on 1 January for box 3. That day is called the reference date. CryptoPeildatum gives you an indication of the value on that day, not a tax calculation.
Which coins
You can choose from coins that are or were traded against the euro on Bitvavo, Coinbase, Kraken, Binance, Bitstamp or Crypto.com, including coins that have since been delisted. If a coin was not yet traded against the euro on the chosen platform on a reference date, it has no price for that year.
Choosing another reference date
When you choose another date, we fetch the price on that day for all your coins. The amounts you entered stay the same. If you owned different amounts on that date, update them with “Edit”.
Missing prices
If a coin has no price, your overview and the CSV say so. That coin is left out of the total, which is then marked as incomplete. Use “Retry prices” to try again.
The CSV
“Download overview” gives you a CSV file with your coins, amounts, platforms, prices and values, the total, the reference date and time, and the price source. You can open it in Excel, Numbers or Google Sheets. You can import that file again later, for example in another browser or as a starting point next year.
What the tool does not do
CryptoPeildatum does not retrieve your transaction history and does not connect to your exchange or wallet. You enter what you owned yourself. If your coins are on a platform other than Bitvavo, Coinbase, Kraken, Binance, Bitstamp or Crypto.com, the price there may differ.
The tool does not calculate tax. For advice about your tax return, consult a tax adviser.
Sources and use
We retrieved the prices from the public APIs of Bitvavo, Coinbase, Kraken, Binance, Bitstamp and Crypto.com and store them ourselves; the calculator does not contact the exchanges. The rights to these prices belong to the exchanges. We do not grant permission to reuse them; if you want to reuse them, check the terms of the exchange itself.
The texts and the calculation method on this site belong to CryptoPeildatum. We are independent of these exchanges and not endorsed by them.
