Yeah, I've been looking at that nightmare too. The accounting costs will put many small businesses out of business overnight.
I can't even begin to imagine what would happen which leads me to believe that the gov't will either find a way to make it easier for us or the small business associations will ban together and revolt in some way - either ignoring the tax altogether, lobbying against it, supporting politicians who oppose it, etc.
I just can't see what amounts to multi-multi-billion dollar industry of individuals being regulated in such a way.
I feel that it is the state citizens who should list what they've purchased from out of state and file that along with their taxes.
Very few if any would actually do it but they don't and won't get penalized so why should we?
We are one nation and I think we need one solution - not 50 individual ones.
