381. Alteration of accounting reference date

(1) An LLP may by notice given to the Registrar specify a new accounting reference date having effect in relation to —
(a) the LLP's current accounting reference period and subsequent periods, or
(b) the LLP's previous accounting reference period and subsequent periods.
An LLP's "previous accounting reference period" means the one immediately preceding its current accounting reference period.
(2) The notice must state whether the current or previous accounting reference period —
(a) is to be shortened, so as to come to an end on the first occasion on which the new accounting reference date falls or fell after the beginning of the period, or
(b) is to be extended, so as to come to an end on the second occasion on which that date falls or fell after the beginning of the period.
(3) A notice extending an LLP's current or previous accounting reference period is not effective if given less than five years after the end of an earlier accounting reference period of the LLP that was extended under this section.

This does not apply —
(a) where the LLP is in administration under Part 1 (administration) of the Insolvency Regulations 2015, or
(b) where the Registrar directs that it should not apply, which he may do with respect to a notice that has been given or that may be given.
(4) A notice under this section may not be given in respect of a previous accounting reference period if the period for filing accounts and reports for the financial year determined by reference to that accounting reference period has already expired.
(5) An accounting reference period may not be extended so as to exceed 18 months and a notice under this section is ineffective if the current or previous accounting reference period as extended in accordance with the notice would exceed that limit.

This does not apply where the LLP is in administration under Part 1 (administration) of the Insolvency Regulations 2015."
