My expanded question is, do you collect sales taxes on internet sales of pictures or products (such as a T-Shirt with a photo on it) when the buyer is in the same state as you are? I use a Zenfolio website and all the prints are made by other vendors such as MPix. Zenfolio offers an option to charge sales tax. Since I am just getting started into professional photography I don't want to run afoul of the state of Florida for failure to collect sales taxes. I would be interested in what experienced professions do. Thanks!
