The short answer is yes, I'm afraid you are. Tax is a pretty complicated area (hence tax lawyers and the like get paid oodles to try and fathom it all out!). Generally speaking, presuming you are a UK resident, you would be subject to UK taxes on investments in other countries. Gets bit more complicated if you are a UK national residing in another country, but I won't go into that. You would be subject to income tax on any dividends etc. received on the shares and potentially liable to CGT on disposal of the shares if you make a profit, though CGT is not payable unless you make a gain of more than �7,000 in total, for all investments etc, each tax year. Obviously, I don't know your circumstances, so this is just general guidance for you.
