For example if you have a spread betting account but move to Australia, different rules would apply as apposed to say, having an ISA and moving to Canada. Hi you move to an alternative country you'd have to open a direct account with that office, this is due to different legal jurisdictions among other things. This will really depend on the account type that you have, and where you are moving to.
If i can, anyone know if tax might be applied if i was to withdraw significant gains accumulated whilst living abroad? If moving from UK and taking residence in another country, can i leave futures positions open in my spread betting account?
