Abba_S – Agree with akuperma. If you have an Israeli mortgage, you will want an Israeli account, even if you don’t live there. Your accountant will be able to figure out if you owe anything, and how much.
The big deal is when you “hide” the money, like the PM of Iceland who resigned.
P.S. How awesome is it the the Pirate party is going to win elections (if they happen) 🙂
