> They don't pay as much tax as they should so the income stats are way up

What do you mean by "the income stats are way up"?

That the GDP stats are skewed but the taxes aren't there. So it looks as if Ireland is doing much better on paper than what is happening in reality. Normally with that kind of GDP you'd also have a solid tax base to go with it, here it is the opposite, Ireland has that GDP because their corporate taxes were super low.
