I am sorry, but you are wrong here. There is no other way to read the bill. 'In all disputes', not in business disputes. "In all disputes".
`SEC. 506. BURDEN OF PERSUASION AND BURDEN OF PRODUCTION. `In all disputes concerning taxes imposed by this subtitle, the person engaged in a dispute with the sales tax administering authority or the Secretary, as the case may be, shall have the burden of production of documents and records but the sales tax administering authority or the Secretary shall have the burden of persuasion.
No matter how clear it is, there is not one NRSTer who is honest enough to admit what the bill clearly says.
No one is denying that the bill says that. However, what you seem to be denying is that you have the context of that section incorrect -- it is only in reference to those already required to file reports, not to everyday retail purchases. In other words, depite your claim, John Doe does not have to produce receipts for his purchases.
This is for those who collect and remit - retailers. There is nothing indicating individuals need receipts.
