Hi, Kevin,
I read the tax existing issues in the forum, then I also like to report the similar issue in Tax using tax table. The shopping cart item cannot recalculate the tax when I change the shipping address from NS (Nova Scotia) to BC (British Columbia).
I set up Tax table for HST in Canada:
AB 5.0 (%), BC 12 (%), MB 5 (5), NS 15 (5), ON 13 (5) etc.
I choose a product, then add to cart, then tax will not refresh with shipping address tax state I specify. Similar issue "Tax Calculation Problem 4.67" by Hon D on 11/29/2011.
