I thought New Berlin was one of the lower tax rates especially for how good the location is, IMO. I love the location of being in StAllis but we plan to move further out, probably Waukesha County at some point for more space among other reasons. I was born and raised in Muskego and am somewhat partial to that city but would feel a bit weird living there and possibly having kids go to the same school(s). I personally wouldn't move somewhere purely on the tax rate.
