CTM06130 - Corporation Tax: company reconstructions: apportionment of profits and losses

ICTA88/S343 (9), (10) & (12)(a)

Computing the profits and losses of notional trades

The loss streaming rules ( CTM06120) require a computation of the profits and losses of separate notional trades.

The losses and profits of those notional trades on are worked out using normal taxation principles. Section 343 (9) as amended by Section 343 (12)(a) simply provides that 'any necessary apportionment shall be made of receipts or expenses’. In some cases the apportionment can be made from branch or management accounts. Where there are no such accounts, apportionment should be made on any basis that produces a sensible result, for example apportionment by:

  • time,
  • sales,
  • square footage, or
  • production costs.

Apportionment affecting two or more companies

Apportionment of profits or losses under Section 343 (9) can affect two or more companies, typically on the division of losses on the split of a trade. The effect of Section 343 (10) is to ensure the same basis applies to all the affected companies.

In the event of a dispute all the companies concerned should be consulted and made aware of their opportunity to be heard by, or to make written representations to, the Commissioners.

Commissioners determine an apportionment dispute as if it were an appeal. The rules of jurisdiction are set out in Section 343 (10) itself.

Any case that needs the Board’s direction under subsection 10(b) should be submitted to CT&VAT (Technical). Files of all the companies concerned should be sent with the report that should set out:

  • the nature and details of the dispute,
  • full details of the Commissioners' Divisions concerned, and
  • the reasons given by the parties for their choice of Division.
