Hi there,
I am having the above issues and I am not quite sure as to how I can fix it.

I have seen it before and addressed it, but can't remember how...

Any assistance would be appreciated.

Thank you,
Chris

Never mind, all fixed.

First of all, this has nothing to do with any template or any of our extensions. You need to configure shopper group-specific Tax rules, so the tax gets applied only when the user is logged in to the site. That is a standard VirtueMart feature. Please visit the official VirtueMart forum for such general VirtueMart queries. Here is a related discussion which you can refer to for better understanding - forum.virtuemart.net/index.php?topic=108301.0
