They don't expect that at all. This bill requires tax code simplification before a state may tax out-of-state sellers. There will only be one taxing entity per state, with one database of tax rates and boundaries, and one nationwide rule for determining the locality of the tax. It's still going to be complicated (up to 50 returns, 50 possible audits, and in the worst case 50 subtly different definitions of what's taxable), but nothing like what you're describing.
