Trading in / from Italy

Hello

I am UK resident and trade with uk companies. I have a cousin in Italy who is thinking of starting. He has asked me for advice.

Can he register and trade with UK companies?
Is trading tax free in Italy like it is in UK?

Thanks

As far as I know, only spread betting is tax free in UK. I doubt that Forex trading is tax free in Italy. Whether he'll be able to trade with the UK companies depends on the exact policies of the particular companies, but in general there shouldn't be any problem.
