Paragraph 67 Late accounting date rules
United Kingdom
This paragraph applies if—
the standard part of the basis period for the tax year 2023-24, or
any transition part of that basis period,
ends with 31 March or 1, 2, 3 or 4 April 2024 (“the late accounting date”).
For the purposes of Chapter 2 of Part 2 of ITTOIA 2005—
treat the profits or losses of the period beginning immediately after the late accounting date and ending with 5 April, as nil, and
treat the actual profits or losses of that period as arising in the tax year 2024-25.
The trader may, on or before the first anniversary of the normal self-assessment filing date for the tax year 2023-24, elect for sub-paragraph (2) not to apply.
If an election under sub-paragraph (3) has effect—
there is a transition part of the basis period for the tax year 2023-24 (whether or not there would otherwise be such a part), and
that transition part ends on 5 April 2024 (instead of the date on which it would otherwise end).
