On my new store I only charge sales tax for in-state transactions.
I have made 3 out-of-state sales so far, and in all three cases the Shipping Address has shown the correct state, but the Billing Address shows my state instead, triggering the tax and adding it to the transaction.
I have tried re-creating this error but haven't been able to. So I don't know how to fix it, nor can I determine why it has happened to all 3 out of state customers.
Has anyone experienced this in their store, and how did you fix it?
