The trick here in NH is to move to one of the low tax towns.
NH does not have an state income or sales tax.
However, we have high property taxes primarily to pay for the local schools. There are some small towns like Tuftonboro that do not have a school system. Their property taxes are much lower than average in the state. As long as you are not on the lake front.
If you combine that, with no sales or income tax it makes that location literally one of the lowest tax burden spots south of Alaska.
Whichever school district that the kids attend school at has to get a portion, though, right?
