Hi Jim,
you are supposed to declare whatever earnings in euros you got from crypto trades in annex g section 13001, or as "rendimentos obtidos no estrangeiro" if all the trades were done abroad. Either way the tax is the same.
I'm sorry, but where exactly did you see that?
I'm thinking of getting into crypto trading, but i also want to be sure i'm doing the "proper taxes".
The law is completely absent when it comes to anything crypto related.
Buying and selling BTC is not regulated in Portuguese law, therefore we don't have to pay anything.
If this is a crime, show me the law I'm breaking will you? Please?
How do you explain your profits to the fiscal authorities then (especially if they are big)? They might think you stole, or got them througth other illegal activities.
I think you are making a mistake, you should be careful and honest when it comes to taxes.
