The principal taxes the various government entities are concerned with here are income tax(federal and perhaps state) and sales tax(state and perhaps local municipalities. I got into it with my State taxing office that wanted me to collect and pay sales tax even though I only do 1 or 2 shows a year and just sell items out of my own personal collection.
They finally backed off on this.
