Only 1 of the 3 photographers we've interviewed says there will be taxes in addition to his fees. He's not providing any albums or prints, just the disk of photos. It seems to me there shouldn't be taxes on pure professional/artistic service. I'm a lawyer, and I don't have to pay special taxes if I write someone's will; just income taxes, which I factor into my fees.
I'll research it like a lawyer, just curious what others have experienced on the issue.
