I don't know about the tax affairs when it comes to options trading in Ireland but if it does turn out to be a dead end, you might want to look into spread betting or CFD trading. Essentially the same thing but I know for a fact spread betting is tax free.
Cap gains is 33% on the gain of shares sold regardless of share location. The first 1270 of cg tax is exempted. If you set up a joint a/c with somebody else then the exemption doubles
If I wanted to buy Irish Bank shares tomorrow, what's the easiest and cheapest way for me to do that?
One person's stupidity is another's friendly advice. You're welcome.
It's not 1,270 of tax, it's an allowance for the first 1,270 of Gains. (So it's worth about €409 in tax).
