Income tax is the primary way any state earns income. Without state income taxes, though, how do these states make money? Higher property taxesHigher random fees (speeding tickets, car registration etc)HIgher Sales tax!
This depends. In order for property, sales tax, and other fees to add up to your income tax, you would have to really be spending a lot!The other question is: do you really want to live in the states without income tax?
If making a purely financial decision, then a state without income tax for high income earners can save you a lot of money.BUT: life is short! don't sacrifice happiness for the sake of saving money either!
