For a long time now Sage users have been processing supplier invoices against EC Suppliers & as part of this if it is against a (usually) taxable supply you would select tax code 8 (E C Standard rate at 20%). This is to allow for the notional tax to be calculated & reflected accurately in the VAT return. For years many site have been manually zeroing this out as it **appears** as if this will incorrectly post the supplier transaction since the gross total displayed shows the net + VAT where in reality what happens is the VAT isn't actually added to the gross amount when posted. This came more to light over the last 6 months with the MTD upgrades & whilst users were re-educated in this area it would be sensible that for transactions containing an EC supply tax value that this is not included in the gross value calculated on screen to stop further mistakes occurring in future as staff/users change. Sage would also do well to correct the miscoding of ec supplier accounts default tax code from 7 to 8 as this misleads users by poor example.
