Computation of liability: basis periods - year after ineffective change of accounting date
S219 Income Tax (Trading and Other Income) Act 2005
Where there was a change of accounting date in the previous tax year, but the three conditions in BIM81045 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 BIM81045 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 BIM81060 illustrate this.
