If A. runs a UK registered business - an online shop - from France, using a GB EORI number to dispatch orders to the UK (from France). Do they need to be VAT registered in the UK (VAT registration was optional so far) or do they have to register with the French VAT as the goods are being kept in and sent from France? Most of their customer base is in the UK and they are not.
Also, as a UK business sending commercial goods to customers in the UK, do their customers still have to pay import tax upon receiving the goods?
I'm very confused on this, I'm hoping that someone on here will have the answer :)
