This would be major step and unlikely to be undertaken unless there were other reasons as well as just tax saving.

Moving abroad means you no longer have to pay income or capital gains tax, but remain liable for inheritance tax.

It can be possible to change your domicile and so avoid tax but you need very special reasons to do so. Not least of all do you really want to live abroad and die abroad? Many people change there mind and return to the UK before they die thus creating enormous problems.

If you have major family ties abroad it could be for you but take advice first.

Choosing the right country is also important - not much point moving to a country with worse tax rules than ours.

Italy has no Inheritance Tax at them moment but this is likely to change. France and particularly Spain can be very expensive places to die.

Australia is about the only place free of the Inheritance Tax curse.
