Corporation Tax Act 2010

Post-commencement supplement

321 Supplement in respect of a post-commencement period

(1) A qualifying company which incurs a ring fence loss (see section 323) in any post-commencement period may claim supplement under this section (“post-commencement supplement”) in respect of—

(a) that period, or

(b) any subsequent accounting period in which it carries on its ring fence trade.

(2) Any post-commencement supplement allowed on a claim in respect of a post-commencement period is to be treated for the purposes of the Corporation Tax Acts (other than the post-commencement supplement provisions or Part 4 of Schedule 19B to ICTA) as if it were a loss—

(a) which is incurred in carrying on the ring fence trade in that period, and

(b) which falls in whole to be used under section 45 (carry forward of trade loss against subsequent trade profits) to reduce trading income from the ring fence trade in succeeding accounting periods.

(3) Paragraph 74 of Schedule 18 to FA 1998 (company tax returns etc: time limit for claims for group relief) applies in relation to a claim for post-commencement supplement as it applies in relation to a claim for group relief.

(4) In this Chapter “the post-commencement supplement provisions” means this section and sections 322 to 329.

322 Amount of post-commencement supplement for a post-commencement period

(1) The amount of the post-commencement supplement for any post-commencement period in respect of which a claim under section 321 is made is the relevant percentage for that period of the reference amount for that period.

(2) If the post-commencement period is a period of less than 12 months, the amount of the supplement for the period (apart from this subsection) is to be reduced proportionally.

(3) Sections 325 to 329 have effect for the purpose of determining the reference amount for a post-commencement period.

323 Ring fence losses

(1) If—

(a) in any post-commencement period (“the period of the loss”) a qualifying company carrying on a ring fence trade incurs a loss in the trade, and

(b) some or all of the loss falls to be used under section 45 (carry forward of trade loss against subsequent trade profits) to reduce trading income from the trade in succeeding accounting periods,

so much of the loss as falls to be so used is a “ring fence loss” of the company.

(2) In determining for the purposes of the post-commencement supplement provisions how much of a loss incurred in a ring fence trade falls to be used as mentioned in subsection (1)(b), the following assumptions are to be made.

(3) The first assumption is that every claim is made that could be made by the company under section 37 (relief for trade losses against total profits) to deduct losses incurred in the ring fence trade from ring fence profits of earlier post-commencement periods.

(4) The second assumption is that (where appropriate) section 42 (ring fence trades: further extension of period for relief) applies in relation to every such claim under section 37.

(5) This section is subject to section 324 (special rule for straddling periods).

(6) This section has effect for the purposes of the post-commencement supplement provisions.

324 Special rule for straddling periods

(1) This section applies if the period of the loss is the deemed accounting period under section 309(3) beginning on 1 January 2006 (“the deemed accounting period”).

(2) The amount of ring fence loss in the deemed accounting period is determined as follows—

• Step 1

  Calculate so much of the ring fence loss in the straddling period as, for the purposes of Part 4 of Schedule 19B to ICTA, is attributable to qualifying E&A allowances for the straddling period.

  The amount given by this step is “the qualifying Schedule 19B amount”.

• Step 2

  Calculate so much of the ring fence loss in the straddling period as is attributable to allowances for the straddling period under Part 6 of CAA 2001 in respect of relevant expenditure.

  For the purposes of this step “relevant expenditure” means expenditure incurred by the company on or after 1 January 2006 which, but for that fact, would be qualifying E&A expenditure for the purposes of Schedule 19B to ICTA.

  For the purposes of this step a ring fence loss is attributable to those allowances so far as the amount of the loss (less the qualifying Schedule 19B amount) does not exceed the amount of those allowances for that period.

  The amount given by this step is “the amount of the post-1 January 2006 E&A allowances”.

• Step 3

  Deduct the qualifying Schedule 19B amount and the amount of the post-1 January 2006 E&A allowances from the amount of the ring fence loss in the straddling period.

• Step 4

  Apportion the remaining amount of that loss (if any) to the deemed accounting period in proportion to the number of days in the deemed accounting period that fall in the straddling period.

  The amount given by this step is “the amount of the apportioned loss”

• Step 5

  The amount of the ring fence loss in the deemed accounting period is the amount of the apportioned loss plus the amount of the post-1 January 2006 E&A allowances.

(3) In this section “the straddling period”, in relation to a qualifying company, means an accounting period of the company—

(a) beginning before 1 January 2006, and

(b) ending on or after that date,

disregarding section 309(3).

(4) In this section references to the ring fence loss in the straddling period are to that loss determined on the assumption that the straddling period is the period of the loss for the purposes of section 323.

(5) This section has effect for the purposes of the post-commencement supplement provisions.

325 The pool of ring fence losses and the pool of non-qualifying Schedule 19B losses

(1) For the purpose of determining the amount of any post-commencement supplement, a qualifying company is to be taken at all times in its post-commencement periods to have a continuing mixed pool (the “ring fence pool”) of—

(a) the carried forward qualifying Schedule 19B amount (if any),

(b) the company’s ring fence losses, and

(c) post-commencement supplement.

(2) The ring fence pool continues even if the amount in it is nil.

(3) For the purpose of determining the amount of any post-commencement supplement, a qualifying company is also to be taken in its post-commencement periods to have a non-qualifying pool consisting of the carried forward non-qualifying Schedule 19B amount.

(4) But the non-qualifying pool ceases to exist when the amount in it is reduced to nil.

(5) In this section—

• “the carried forward qualifying Schedule 19B amount”, in relation to a qualifying company, means the amount in its qualifying pool for the purposes of Part 4 of Schedule 19B to ICTA immediately before 1 January 2006, and

• “the carried forward non-qualifying Schedule 19B amount”, in relation to a qualifying company, means the amount in its non-qualifying pool for the purposes of Part 4 of Schedule 19B to that Act immediately before 1 January 2006.

326 The ring fence pool

(1) The ring fence pool consists of—

(a) the carried forward qualifying Schedule 19B amount (if any),

(b) the company’s ring fence losses, allocated to the pool in accordance with subsection (2)(a), and

(c) the company’s post-commencement supplement, allocated to the pool in accordance with subsection (2)(b).

(2) The allocation of ring fence losses and post-commencement supplement to the pool is made as follows—

(a) the amount of a ring fence loss is added to the pool in the period of the loss, and

(b) if any post-commencement supplement is allowed on a claim in respect of a post-commencement period, the amount of that supplement is added to the pool in that period.

(3) The amount in the ring fence pool is subject to reductions in accordance with the following provisions of this Chapter.

(4) If a reduction in the amount in the ring fence pool falls to be made in any accounting period, the reduction is to be made—

(a) after the addition to the pool of the amount of any ring fence losses allocated to the pool in that period in accordance with subsection (2)(a), but

(b) before determining, and adding to the pool, the amount of any supplement claimed in respect of the period,

and references to the amount in the pool are to be read accordingly.

(5) In this section “the carried forward qualifying Schedule 19B amount”, in relation to a qualifying company, means the amount in its qualifying pool for the purposes of Part 4 of Schedule 19B to ICTA immediately before 1 January 2006.

327 Reductions in respect of utilised ring fence losses

(1) If one or more ring fence losses are used under section 45 (carry forward of trade loss against subsequent trade profits) to reduce any profits of a post-commencement period, reductions are to be made in that period in accordance with this section.

(2) If the company has a non-qualifying pool, the amount in the non-qualifying pool is to be reduced (but not below nil) by setting against it a sum equal to the total amount used as mentioned in subsection (1).

(3) If—

(a) any of that sum remains after being so set against the amount in the non-qualifying pool, or

(b) the company does not have a non-qualifying pool,

the amount in the ring fence pool is to be reduced (but not below nil) by setting against it so much of that sum as so remains or (as the case may be) a sum equal to the total amount used as mentioned in subsection (1).

(4) If the post-commencement period is the deemed accounting period under section 309(3) beginning on 1 January 2006 (“the deemed accounting period”), the amount of the profits of the deemed accounting period is determined as follows.

(5) The amount of the profits of the straddling period is apportioned to the deemed accounting period in proportion to the number of days in the deemed accounting period that fall in the straddling period.

(6) The apportioned amount is taken for the purposes of this section to be the amount of the profits of the deemed accounting period.

(7) In this section “the straddling period”, in relation to a qualifying company, means an accounting period of the company—

(a) beginning before 1 January 2006, and

(b) ending on or after that date,

disregarding section 309(3).

328 Reductions in respect of unrelieved group ring fence profits

(1) If there is an amount of unrelieved group ring fence profits for a post-commencement period, reductions are to be made in that period in accordance with this section.

(2) If, after making any reductions that fall to be made in accordance with section 327, the company does not have a non-qualifying pool, the remaining amount in the ring fence pool is to be reduced (but not below nil) by setting against it a sum equal to the aggregate of the amounts of unrelieved group ring fence profits for the period.

(3) If, after making any reductions that fall to be made in accordance with section 327, the company has an amount in a non-qualifying pool, the amount in that pool is to be reduced (but not below nil) by setting against it a sum equal to the aggregate of the amounts of unrelieved group ring fence profits for the period.

(4) If any of that sum remains after being so set against the amount in the non-qualifying pool, the remaining amount in the ring fence pool is to be reduced (but not below nil) by setting against it so much of that sum as so remains.

(5) For the purposes of this section references to the remaining amount in the ring fence pool are references to so much (if any) of the amount in the ring fence pool as remains after making any reductions that fall to be made in accordance with section 327.

329 The reference amount for a post-commencement period

For the purposes of section 322 the reference amount for a post-commencement period is so much of the amount in the ring fence pool as remains after making any reductions required by section 327 or 328.
