VAEC7840 | Error correction for VAT returns: Processing: Initial check for credibility
From HM Revenue & Customs · VAT Assessments and Error Correction
Officers should check the credibility of the information provided to determine whether further information should be requested to verify the error correction notification. In particular, they should consider
electronic folder or local file details
history of disclosure
relationship to last visit
new registration
oral notifications not followed up in writing, and
large amounts in ‘gross amount over-declared box’ on the error correction notification.
In addition, the assessing time limits should be borne in mind, since HMRC may be time barred from making a recovery assessment should it subsequently be discovered that an error notification was incorrect.
