There's something I haven't seen addressed and that is.. in order to remit a tax as a seller you have to have an account.
So I have this nifty software that calculates all the state , municipal district and so forth taxes. I can't just put them in an envelope and mail them to state of Colorado because most of them are home rule districts.
So this means I would have to apply for a sales tax license in every possible District or City.
Those aren't free typically there's a fee for that. Then those accounts need reports periodically whether you have sold anything or not.
So yes Amazon is equipped to handle this I would imagine but as a small seller even at $100,000.. the logistics of actually paying said taxes will be daunting.
Unless the state has put some means in place for distributing taxes paid to a central account.
But I have heard nothing to that effect
