Thank you for the help. I think I have done all of that, in several different ways, to no avail. I either get all of the states in the US taxed, or none. What I need to do is only apply tax if the buyer lives in one particular state, the state in which I am established. So here is what I did:
1) In zones, I unpublished all countries except US.
2) In US zone, I removed subzones which were not continental US.
3) With that, now my checkout enter address looks like it needs to for the places in which I do business.
4) I created a tax zone, called FL Tax which has a subzone including FL state only.
5) Created Tax Category called Taxable Sales
6) In my products, I reference that Tax Category
7) Created Tax Rate of 7% for FLorida
Created Tax Rule linking Category, Rate, customer type, and zone.
9) In Configuration, I reference the tax zone I had created with only FL in it.
Now what I get depends on how I set the zone in the Tax Rule. Are you supposed to set the rule to point to the geographical zone or the tax zone? Of course either way does not work for me. One way ends up with state taxed or none of them taxed. What am I missing?
Thank you for any help.
