Might I suggest that before you ask any more questions you take a look at the information already given in the Threads in the various parts of the Forum. It will soon be midnight and the night owls on here are not likely to be too keen to answer questions for someone who hasn't checked things out already.
Taxes in Neuchatel are quite high compared to other places. But accomodation is more readily available to rent, at much lower prices that Lausanne, Geneva or Zurich - and house prices much lower- especially if prepared to travel a bit out of town.
Odile is right, Taxes are higher but the bottom line is not that bad.
You can calculate/compare yourself the taxes there. http://en.comparis.ch/steuern/quelle...r/default.aspx
...this is the general rate calculato, no idea if there a special rate for Italians ;-)
