This is the period to which the details provided of income and
expenses, tax adjustments and balance sheet, relate.
Relevant boxes (1.4 and 1.5) should be completed by the
taxpayer to indicate the start and end dates of the accounting
period used to complete the details on the Trade supplementary
pages.
Basis Period
This is the period used to identify the profits which are
taxable in any particular tax year (normally the 12 month period up
to the annual accounting date).
Relevant boxes (1.74 and 1.75) should be completed by the
taxpayer to indicate the start and end dates of the income tax
basis period.
Capture of Dates
In a few cases the two sets of boxes may properly contain
different dates because the accounting period and basis period will
not always be the same. However, in most cases the two sets of
dates are the same.
Note: It is therefore not considered reasonable to
reject a return where dates are given in one set of boxes but not
repeated in the other set of boxes.
