CFM96220 | Interest restriction: related parties: general rule
From HM Revenue & Customs · Corporate Finance Manual
The general rule is that A and B are related parties on a particular day where any one of three conditions is satisfied:
1. The consolidation condition
A and B meet this condition if:
Their financial results for a period are required to be comprised in group accounts.
Their financial results for the period would be required to be comprised in group accounts, but for the application of an exemption.
Their financial results for a period are actually comprised in group accounts.
Group accounts means accounts prepared under section 399 of the Companies Act 2006, or any corresponding provision of the law of a territory outside the United Kingdom.
2. The participation condition
A and B meet this condition if, within the period of six months beginning or ending with that day, either of the below are met:
Either A or B directly or indirectly participates in the management, control or capital of the other; or
The same person or persons directly or indirectly participates in the management, control or capital of both A and B.
Whether a company participates in the management, control or capital of the other is determined in a similar way as for transfer pricing. But unlike for transfer pricing, TIOPA10/S161 and S162 do not apply when determining the participation condition for CIR purposes.
Where either A or B is a securitisation company, they are not treated as related parties if this treatment only arises by virtue of the securitisation company being held by a trustee of a settlement with the other party being a settlor of that settlement.
Example
A Ltd has one wholly owned subsidiary (B Ltd) which it disposes of to an unrelated party on 1 April 2017. The participation condition is met up to this date because A Ltd directly controls B Ltd. A Ltd and B Ltd will continue to be related parties up until 1 October 2017, because this is six months from the day the condition was last met.
3. The 25% investment condition
A and B meet this condition on any day where either A or B has a 25% investment in the other or a third person has a 25% investment in both A and B.
