The European Commission aims for the new rules to be enforced on Jan 1. 2026.
It won't be easy. This is only a proposal. This may change greatly in the future while all the possible (and impossible) aspects are negotiated between all the parts and parties.
Then this has become part of the national laws in all the member countries. Here it will change again, in some countries will become stronger and in others weaker.
And I will add that some European countries do better and others do (much) worse at collecting the taxes and the taxation related information.
So, depending on the country, this will become reality (or maybe it already is) and in the case of other countries it's more a "wishful thinking".
I don't say that taxation won't happen, the governments are always hungry for money.
(I wish that we'll get someday to the point only active traders will get taxed, and that on the gains; but let's ignore the wishful thinking).What I say is that really tight taxation won't happen too soon.
