[4.x]: Tax rate is calculated on shipping address, not on billing address

[rauwebieten]

What happened?

Description

It seems the tax rate is calculated based on the submitted shipping address, and not on the billing address.

Steps to reproduce

I have setup my different tax rates and zones, as explained in the docs.

Expected behavior

When modifying my cart in the admin: When choosing a billing address, i expect the tax to be calculated. It is not being calculated, unless I choose a shipping address.

I understand that when templating the cart system, you can check the checkbox that says "same billing address as shipping". Then the calculation will be correct.

In our case, we're building a website with digital products. We do not need a shipping address configured in our cart/order. We can fix this for now by simply setting the shipping address equal to the billing address.

But... There is a case this way of working is not correct. (with physical products) As a customer, I can place an order from a company (in Belgium for example), and send it to a different shipping address (in France for example). I expect the the tax calculation to be based on the billing address (BE) and not on the french shipping address.

@rauwebieten would this setting be the solution?

Ok, great! That would be the solution I guess. Will test later.

This should be included in the docs/guides :)

Thanks
