VAT Assessments and Error Correction

How to assess and correct: VAT Amendments: Processing VAT643

Once you have completed the form, it should be captured into the trader’s folder in EF and forwarded to the Authorising Officer who should then forward it to the VALID pre-input control seat for input into the VAT Mainframe

Information on capturing, attaching secure notes and forwarding documents in EF can be found in the EF user guide on the VSLT website System Owner Team 

However, before the file is actually updated, a number of checks are carried out and the document may be rejected. The errors that will cause the VAT643 to be rejected are detailed in the D0502 Print which is sent to the VALID Team responsible for inputting the VAT643, who will return the original form to the Assessing Officer for amendment. Alternatively details of the errors will be available for viewing via PRADA.

A VAT656 will be generated showing the same OA reference number as the original officer’s assessment and a copy will automatically be downloaded into the trader’s folder in EF.
