"Although there is no legal definition of what 'an assessment has been made' means, the courts have interpreted the law to mean that an assessment is made once you have finished calculating the amount of tax due and a final decision to assess that amount has been taken. This is normally considered to be when the amount has been • quantified • documented • checked • signed and dated. The documentary evidence of having made an assessment may be, for example the signed and dated schedules. The raising of a form VAT641, the computer input document for the notification of an assessment, is the first stage in the notification process and is a consequence of the decision to assess, rather than the actual making of the assessment itself… The VAT641 should normally be raised on the same day as the assessment is raised or shortly after." 195. VAEC6510 reads: "
"Once you have completed the VAT641 and it has been checked, you should capture the form to the trader's folder in EF and forward (with a secure note attached) to the authorising officer. The authorising officer will then look at case details in the penalty toolkit in SEES (until NPS becomes available) and EF, authorise the VAT641, update the secure note and forward to the VALID team for input… The information which is keyed from this document will be transferred to the VAT Mainframe and processed overnight to update the trader's files." 197. VAEC6520 is headed "
"The decision on whether or not a countersignature is required in the following circumstances is not delegated. Countersignatures are required to provide internal management assurance where: • There is a net over-declaration within an accounting period, or • There is a reduction or withdrawal of an assessment, or • The assessment is complex. Ensuring it has been checked by an independent check officer, should reduce the risk of error or challenge. It should be noted that countersignatures are an internal management assurance tool and do not form part of the making of an assessment. A countersignature is not required to make an assessment."
"On 10 May, Mr Walsh prepared a form 641 (an officers assessment). He completed it by hand and incorporated his original figures produced to the Appellant on 10 March except for the revised figure for 5/96 and the resulting annual adjustment. Mr Walsh signed the form as "assessing officer" and dated it10 May 1999 . The form was then also signed and dated10 May 1999 by a Mr Thomson as 'check officer'. Not all officers assessments need additionally to be countersigned by a senior officer but there are certain stipulated circumstances when they must be…The date of Mr Lambert's countersignature was a subject of dispute between the parties and as both parties agreed that the date of the counter-signature would be the date the assessment was raised it was clearly a matter of critical importance." 209. Having considered the evidence, Lady Mitting then said at [14] "
"Assessment of VAT is an important step, and it is unsatisfactory that the process is not transparent, and not defined by legislation or even by clear administrative practice. But I do not, on the unusual facts of this case, have to decide on the mechanism by which an assessment becomes complete , as it might be necessary to decide in a case where a time limit falls in the course of completion of the Form 641 process and the generation of the notice of assessment." (5) Although Mr Beale is correct that in Courts at [106] , Parker LJ had cited Cheesman, he did so to emphasise the point made in that case that the Commissioners should standardise their process. He went on to say at [107]: "
