Maybe I am not understanding how this is supposed to work. I am assuming that if I have set all my taxes properly (I imported the Localization pack for the United States). I can see that all of the individual states are listed, with their individual tax rates. I can see that there are Tax Rules for each state with the appropriate rates for each. So, I assume that when the customer enters their state and zip code at checkout, the tax for that sale should be calculated.
Am I missing something or not understanding the process correctly?
