It is advantageous to own one or more tax residences for the possibility of managing an offshore business or different offshore activities by coordinating them with the most suitable tax authority for that activity. It is not a simple question of paying more or less taxes, but of being able to take advantage of Free Trades, in the form of conferences, free trade treaties and even different and often zero taxes.
For the taxable person, however, a tax residence allows him to decide where to be taxed and on the basis of what, deeming one place more appropriate than another.
