Some of my invoiced expenses to companies outside of the UK and which are in QB as 'No VAT' are still being counted towards my VAT return total?

Hello Martinefishpool-a, thanks for posting on the Community page,  so anything with NO VAT on it will not show on the HMRC return. However you may have set up a different NO VAT code that does post or you may be looking at a custom agency which could still pull through the NO VAT amounts to certain boxes.
