When filing VAT returns previously (outside of Quick File), Box 7 of the VAT Return is a sum of all Vatable purchases excluding VAT. One test I was always told to check this was Box_7_Value * 0.2 and the result would be the VAT Reclaimed value (Box 4).
I have just tried to calculate my first VAT Return using Quick File and it seems to use a different logic to the above and seems to total all purchases including ones without VAT. This means Box 7 is no longer a reflection of the VAT Reclaimed value.
No worries sorted it. It seems there are mixed views on what goes in Box 7 - some say all vatable purchases ex VAT, others all purchases inculding non-VAT ones. Both seem to be OK to HMRC, so I will use the QF way of calculating it.
