Include tax based on customer's country - Selling from France to France - Tax NOT inlcuded

I want to use the following settings: https://help.shopify.com/en/manual/taxes/location#include-exclude-based-on-customer-country

It seems whenever the store address is in the same country as the customer - taxes are never included at the cart - only at checkout - why is this?

  • My store is registered in France

  • I have markets for UK, EU and International

I am collecting taxes for UK and EU (France and Hungary)

Shipping to UK includes tax on cart and checkout

Shipping to France - Taxes is not calculated cart!

Shipping to Hungary - Taxes is again calculated at cart

Now if I change my store address to UK - tax is no longer calculated at cart

But now tax is included in the cart for France
