Hi Rachel, thank you so much for this post, it has incredibly helped me a lot with real examples. I just have a quick question you might be able to answer. What about the other way around? I mean: I used to live in the UK and now I’ve moved to Spain (and now I’m VAT registered here in Spain) Do you know if it’s necessary for my UK clients to be VAT registered in order to received invoices from me?

Thank you so much in advance 🙂
