OMG! This thread is a beast! I got over 100 pages deep and haven't found a good answer, so I'm posting.

For some reason, when someone buys a downloadable product (or any product for that matter), GoogleCart isn't charging tax to residents of my state.

At first I had ZenCart handle my taxes, but my downloadable products don't require shipping addresses, so ZenCart never knew if the purchaser was from Texas or not.

THEN I set it up for Google, since they require the address for Credit card processing.

It turns out Google is passive, and doesn't add tax if any tax declaration is output from ZenCart.

So, how do you kill any tax declarations in the GoogleCart Module of Zencart, so GoogleCart can actually do it's job?
