Son is 18. That’s about $43.5k USD. For reference, I earn ~9000 lei per month, and that’s considered a very good salary here. There are still people working for ~2500 lei a month. Son forgot to close this Revolut tab on the living room PC, that’s how I came across it.
This is serious, you need to make sure you know the origins of the money even if it is legit.
Here in Sweden your earnings are reported directly to the tax office, banks are also required to verify the origin of large payments.
How does taxes work in Romania?
Here they are being pulled straight from your salary before you get it, but selling financial instruments works differently, I sold some shares from an inheritance to by a car last year, I had to report the income when doing my taxes, I also had to use a standard earnings calculation as I didn’t know the value of the shares when I got them.
