How do I enter a supplier's VAT invoice into QB so that is impacts the VAT return without affecting the actual bank ledger?

Hi info1759, thanks for joining the Community - if you're using the standard VAT accounting scheme then you can enter the invoice using a bill (+ New icon > bill) with the VAT code selected, this will post the VAT element to the VAT return and you can record then record the bill payment against this at a later date.
