Hey Andy,
Because the savings in bank deposits and stocks was put away mostly by older folks who worked for years to save it. In New Hampshire older folks gets wacked by both their increasing property taxes, and the 5% tax on interest.
As you know very well, NH has no tax on personal income, so by changing a business from an LLC to a DBA, it will become state tax exempt.
The LLC plan was hatched in about 1992 to be somewhat similar to the 'in common use' property tax exemption. Have a piece of land, ten acres or larger, and you pay basically peanuts in prop taxes.
The LLC plan was cooked up as a way to avoid taxes, simlar to 'in common use.'
It all adds up to that well known NH tax game:
.........
Just don't tax me!
Just go tax someone else!
Just welcome to New Hampshire!
