This is a great question! At this moment, we are unable to make changes to the way taxes are being automatically calculated depending on your store location when completing the checkout. However, you can create a Tax override or exemption if you would like to control how much tax you charge for a particular product or specify unique tax rates for shipping destinations.
With that being said, I can certainly see the benefit of allowing you to set up your own formula to automatically calculate taxes so I am going to provide this as a suggestion to our developers.

I have the same problem with many of my invoices. Bookkeepers are making me crazy. Can you please find a solution asap.

Please let me know what solution you have.
Kind regards Marloes Bruijn
