BIM71055 - Computation of liability: basis periods - year after ineffective change of accounting date

Where there was a change of accounting date in the previous tax year, but the three conditions in BIM71045 were not met for the previous year, a change of accounting date is treated as taking place in the next year if accounts are prepared to the new accounting date in that year.

The three conditions in BIM71045 must be satisfied for the next year if the basis period for that year is to end with the new accounting date.

Examples 5 and 6 at BIM71060 illustrate this.
