State tax filing

@CodeGuy on the muscian example, look at sports teams....The Dallas Cowboys are owned by a TX based company.  Every time the Dallas Cowboys play a game in another state, each and every player has to pay tax to the state where the game was played, as they WORKED in that state.  And in fact most of these players file taxes in many. many states as their work takes them to a number of states over the course of the season.
