EU: Netherlands users, remember to document your entire crypto holdings today. De Belastingdienst uses Jan-1st as the snapshot date to value your portfolio.

Tax in The Netherlands is also levied over the total value of your crypto holdings, in the so called 'Box 3'. This entails your assets. (Not to be confused with Box1 for income)

To report on your crypto, you have to provide the value of your entire holdings on January 1st so today is the day to save yourself some future headaches and record your portfolio.

As this is January 2022, the snapshot you take today is used for your taxes over 2022, which you'll be filing in April 2023. Long way away so thus this reminder.

You will not be taxed for the first 50k of combined asset value (crypto, stocks, bonds, savings account etc) If the total value of your combined assets exceeds 50k, you start paying tax on the part that exceeds this 50k threshold*.

*YMMV depending on personal situation

Edit:And if you are a "trader", making (or loosing) money by day trading it might be taxed differently. It's taxed in box1 for income and you need to report small and big losses or gains, not just portfolio value.

If that's the case for you, look for a good source as crypto in Box1 is much more elaborate than what I am sharing here about Box3
