Hi all! I added customers from Canada to our UK subsidiary and want to assign them CA tax codes. After adding the nexuses of Canada to that subsidiary, I can no longer assign the Non-EU tax code. Does anyone know how I can enter the Non-EU tax for the sales transaction of that customer?

I've encountered this with before, and clearing the default billing and default shipping checkboxes on the customer address allows selecting a different tax code. Not sure this is the best solution though

First of all - what are you actually trying to do? A customer from Canada for your UK subsidiary needs a UK export code by default unless you fulfill from a local Canadian entity/warehouse e.g. If you use legacy tax it is sadly quite limited what you can do, suitetax e.g. allows for more tax registrations per customer/sub. If you need a specific tax code with a specific behaviour or booking you can always create a new tax type with codes and control accounts - but note that you have to sort the reporting manually then.
