My take on it is that we have arrangements with certain countries (I am living in Ireland too)
In some cases we might only have to pay 15% but there is alot more variables too this also.
I am still doing my own research and I have not invested yet. I hope someone more knowledgeable can weigh in here. But I do know should be tops 41% or I believe or 20% plus usc prsi if in 1st bracket ect. I would also like to know this even some things I looked up said alot of it can be left to enterpretation, so I am thinking even hiring an expert to just lay this out for myself.
