private placement

I've received the certificate of a number of shares bought in a private placement in the U.S of an Israeli company.
Is it possible to deposit the certificate in another country, sell the shares and so avoiding the U.S. taxes?
Thank you very much for your help

Juanchi,

I'm guessing from a UK perspective. You possibly could but the proceeds would have to stay in the country where the sale took place. When the funds are repatriated to the US, then you will be liable for due taxes. Alternatively, you could go that country and spend the proceeds there.

Grant.
