(1)This Part has effect in relation to accounting periods beginning on or after 1 April 2022.
(2)If an RP developer has an accounting period beginning before 1 April 2022 and ending on or after that date (“the straddling period”), for the purpose of determining whether RPDT is chargeable on the RP developer for the straddling period and, if so, in what amount—
(a)so much of the straddling period as falls before 1 April 2022, and
(b)so much of that period as falls on or after that date,
are to be treated as separate accounting periods.
(3)If it is necessary to apportion an amount for the straddling period to the two separate accounting periods, see section 1172 of CTA 2010 (which applies as a result of section 45).
(4)If—
(a)RPDT is chargeable on an RP developer for the straddling period, and
(b)under the Instalment Payment Regulations one or more instalment payments in respect of the total liability of the RP developer for that period are treated as becoming due and payable before 1 April 2022 (“pre-commencement instalments”),
the RPDT chargeable for that period is to be ignored for the purposes of determining the amount of any pre-commencement instalment.
(5)The first instalment in respect of that liability which is treated as becoming due and payable on or after 1 April 2022 is to be increased by the following amount, namely the difference between—
(a)the aggregate amount of the pre-commencement instalments determined in accordance with subsection (4), and
(b)the aggregate amount of those instalments determined ignoring that subsection (and so taking into account the tax chargeable on the RP developer for the straddling period).
(6)In the Instalment Payment Regulations—
(a)in regulations 6(1)(a), 7(2), 8(1)(a) and (2)(a), 9(5), 10(1), 11(1) and 13, references to those Regulations are to be read as including a reference to subsections (4) and (5) (and in regulation 7(2) “the regulation in question”, and in regulation 8(2) “that regulation”, are to be read accordingly), and
(b)in regulation 9(3), the reference to those Regulations is to be read as including a reference to those subsections.
(7)In section 59D of TMA 1970 (general rule as to when corporation tax is due and payable), in subsection (5), the reference to section 59E of that Act is to be read as including a reference to subsections (4) and (5) of this section.
(8)In this section “the Instalment Payment Regulations” means the Corporation Tax (Instalment Payments) Regulations 1998 (S.I. 1998/3175).
