I've been looking through my seller fee invoices in my Tax Document Library and have noticed that for "AGL Merchant Self Billing Invoices", Amazon are billing me for VAT on these sales. However, I have been paying the VAT on these sales for my quarterly VAT returns.

Should these sales be excluded from my VAT return, and am I entitled to a rebate from HMRC? I assumed that as I'm VAT registered, all VAT is excluded for my seller fee invoices, but I hadn't checked the AGL invoices before. Here is a screenshot from one of the invoice.

Many thanks!
