Help with Tax Issue

[impdesigns]

The physical store is located in North Carolina which has a 7.0% sales tax. The fulfillment company requires that we tax on any items bought in the store based on their shipping address and only on those items shipped to a Northa Caronlina address. Everything is setup in the store admin to tax based on shipping address. This works fine when someone from North Carolina buys from the store and ships to a North Carolina address. The issue we are having is that when someone is out of state, like Virginia, and buying goods from the store, but then shipping back into a North Carolina addresss. Tax is not assesed on the purchase, which needs to be. Any clue on why tax is not being based on the shipping address with this scenario? Thanks in advance.
