Most jurisdictions will come down, theoretically, on a business that is collecting sales tax at a rate higher than authorized/required. For some reason, politicians and bureaucrats don't like being accused (even inadvertently) of being even greedier than legal. Setting aside the snark, there have been many instances of fraudulent tax collection by businesses, so gov't tends to take a very dim view of errors in this realm.
