Hi! You seem to have posted in the pre-sales forum … it’s generally best to post in the WooCommerce Tickets forum if you already have a license (it looks like you do).
In general though, the application of taxes is something that rests at the level of the ecommerce engine and right now we do not support this. It would mean our plugin would need to interfere in the operation of WooCommerce itself – and I don’t think we have any immediate plans to investigate doing so.
With that said, if you want to post a feature request we’d certainly be more than happy to give it further consideration (and, posting a request also means other users can show their support for this idea – you may even find a suitable existing request you can add your own voice to):
I hope that helps 🙂
