Possibly useful data point: I have ZC 2.1.0 + Latest Local Sales Tax, my LST rates *do* include State tax, but I have another state which is also taxed that does not use LST. Ordering with delivery to that state works as expected, with the native Zen Cart sales tax being applied properly.
I did have those changes but I reverted all of those changes to barebones ZC 2.1.0 files. Trying to track down what else could I have changed.
