Online sellers with less than $1,000,000 in remote sales annually will be exempt from collection requirements.
I would think most should want this to pass, it will help local businesses to compete with online sales among other things.
They are not "to make every Internet transaction "fair" by allowing states to throw a sales tax on it"
The taxes are already OWED by the ones making the purchases online, just too much trouble trying to collect from individuals, easier to have the companies collect at the point of sale IMO, than to have me submit them myself or government auditing my online purchases and busting my door in to collect taxes, though I doubt that scenario is realistic, it is possible and legal.
As for a mom and pop complying, with modern software this would be a snap, some have to do this now that are non-internet.
I do think they should include non-internet walk in sales, though.
