Can't Stop Tax Estimates Showing Up

My store is based in Indiana, so I charge 7% sales tax TO INDIANA RESIDENTS ONLY.

I have my store backend settings set NOT to display tax estimates because the vast majority of my customer as NOT in Indiana. However, the cart insists on displaying a sales tax estimate in the shopping cart. Is this a bug?

I submitted a ticket to CS-Cart Support and they said this is a confirmed bug. But as it is considered a “minor” bug, they can take up to 45 days to fix it. Charming.

One of the suggested fixes is to change the default address in my settings to somewhere other than my own state. So, until this bug is fixed, I live in Illinois, not Indiana.
