Commentary on Sections Overview Overview Section 213: Circumstances in which middle date not treated as accounting date
869.This is the third of the three sections that, together, prevent the complex change of accounting date rules from applying in particular circumstances. It ensures that when the middle date treatment ceases to apply no profits are assessed twice and no profits drop out of charge.
870.The section does this by imposing continuity in profit counting between the two relevant basis periods. This is necessary because when a middle date is used to mark the end of the basis period for the earlier year, the actual date to which its profits are calculated may otherwise result in a gap preceding, or an overlap with, the actual date on which the basis period for the following year begins. This section ensures continuity between the two when the basis period for the second year is given by any of the provisions listed in subsection (2).
