From HM Revenue & Customs · COTAX Manual
Exceptionally, you may need to manually make or amend a CT assessment for a CT Pay and File Accounting Period (AP). This may be when:
COTAX is unavailable and you have to make an assessment urgently
you have made an invalid assessment. For more information see COM151120
You prepare manual assessments using:
form SEES 310(Z) to make or amend an assessment
When you use function PAST (Prepare Full Assessment) to record the issue of a manual assessment, COTAX does not issue any output.
COTAX:
retains the details of the manual assessment on the record for the company
does not accept a manually issued assessment containing an arithmetical error. If you have made such an error, you must issue a manual amendment and record those details on COTAX
records the relevant postings, as if it had made the assessment (or amendment)
You can subsequently use function PAST to amend the manual assessment, or make a further assessment in the normal way.
