Notice that Mike Enzi is all for it. Go figure. He has no clue as to what this would do to small businesses. I’ve spent my business career since 1996 helping large corporations navigate multi-state sales and use tax issues (and other excise taxes). Asking a small seller to keep up with the tax laws of thousands of jurisdictions is ridiculous. All it will do is kill small business and create a new bureaucracy.
Yes it will create a crisis and they love those, the only way to solve it will be for all the companies to pay one flat rate to the federal government who will then redistribute some of it back to the states.
Game, set. match.
