Most internet sales that I make are out of state. This is where tax filing will hurt. I am sure that my state, CA, will be very aggressive about collecting sales taxes from out of state retailers who sell to CA residents. Do NY sellers want to get a CA tax number and file in this state? I don't want to get a NY tax number and file every year because I sell a $50 item to a NY resident via the internet.
Me get a CA tax number? Certainly not. In fact I am probably going to get rid of my NY tax number and give up doing shows. The money I take in just is not worth the hassel.
Maybe EBay or Paypal will collect and submit taxes as part of their service.
