Thanks again! It looks like the tax code was created with RF (the administrator who set it up was advised RF was the country code for Reunion - thanks for correcting that). Ireland is our OSS tax nexus. I can amend the code to S-RE-IE, but I'm concerned that all this will do is mean that orders from France comes through…

Here are some screenshots I've been sent

The correct tax code should be S-FR for France, but the order is created using code S-RF for Reunion Island. All affected customers are definitely based in France (living in mainland France, with both billing and shipping addresses set to France) but every single order comes through with S-RF instead of S-FR, so I know it…

Also, there won't be a default tax code on the customer record because they are often new customers purchasing for the first time from our website.

Thanks for the response (I don't work on Mondays so have only just seen your comment). I don't appear to have the menu options to check the tax setup, but I can confirm the following: Shipping (and billing) address are both France, Yes, this is OSS, and France is set up as a Nexus. Reunion Island is NOT set up as a nexus.…

Hi - this answered my question but I clicked "no" by mistake! Initially I thought I didn't have a Submit button, but it was there at the top of the screen, unnoticed!!! (I was never shown how to use this function so didn't even notice it at the top!) Thank you so much!
