Example of relevant interests and interests by virtue of ordinary shares alone

relevant interests and interests by virtue of ordinary shares alone flowchart

The relevant interests arise only through holding ordinary shares. Top Co, A Ltd and B Ltd are all United Kingdom resident companies. The other companies and Signor A are non-residents.

Top Co

Top Co has a ‘relevant interest’ under ICTA88/S752A(2) only in respect of 10% held directly (Rule 1). Its remaining interest does not represent a ‘relevant interest’ as it is held by virtue of other United Kingdom resident companies (ICTA88/S752A(3)).

A Ltd

A Ltd has a ‘relevant interest’ under ICTA88/S752A(2) as none of its interest is held by virtue of an interest in another United Kingdom resident company (Rule 1).

The fractional interest A Ltd has in C Inc. is 0.25 and that C Inc. has in E Inc. is 0.10 (i.e. A Ltd has a 25% interest in C Inc. which itself has a 10% interest in E Inc.). The product ‘P’ is therefore 0.025.

‘S’ is 90%, being the percentage of issued ordinary shares that E Inc., the lowest share-linked company, has in the controlled foreign company.

P x S therefore gives A Ltd a relevant interest of 2.25% (i.e. 90% x 0.10 x 0.25)

B Ltd

B Ltd has a ‘relevant interest’ under ICTA88/S752A(2) as none of its interest is held by virtue of an interest in another United Kingdom resident company (Rule 1).

B Ltd’s interest can be traced through a 75% interest in C Inc. and an 80% interest in D Inc. This requires two computations.

  • The first computation traces an interest through C Inc. The fractions B Ltd holds in C Inc. and C Inc. holds in E Inc. (both C Inc. and E Inc. are share-linked companies) are 0.75 and 0.10 respectively (i.e. B Ltd has an 75% interest in C Inc. which itself has a 10% interest in E Inc.),. The product ‘P’ is therefore 0.075 (0.75 x 0.10).
‘S’ is 90%, i.e. percentage of ordinary shares that E Inc., the lowest share-linked company, holds in the controlled foreign company.

P x S therefore gives a first relevant interest to B Ltd of 6.75%.

  • The second computation traces an interest through D Inc. The fractions here are 0.8 and 0.9 (i.e. B Ltd has an 80% interest in D Inc. which itself has a 90% interest in E Inc.), giving a product ‘P’ of 0.72.
E Inc. is still the lowest share-linked company and ‘S’ therefore remains at 90%.

P x S therefore gives a second relevant interest to B Ltd of 64.8%.

The total interest of B Ltd in the controlled foreign company is therefore 71.55% (i.e. 90% x 0.10 x 0.75 (6.75) by virtue of its holding in C Inc. and 90% x 0.9 x 0.8 (64.8%) by virtue of its holding in D Inc.).

C Inc.

C Inc. does not have a ‘relevant interest’ as the same interest is held by a United Kingdom resident company (Rule 1).

D Inc.

D Inc. does not have a relevant interest as to 80% of its interest in E Inc. as the same interest is held by a United Kingdom resident company (Rule 1). (It does not have a relevant interest in relation to the interest of Signor. A as his interest is indirectly held by another related person (E Inc.)) (ICTA88/S752A(5) (Rule 2).

E Inc.

E Inc. does not have a ‘relevant interest’ to the extent that United Kingdom companies hold the same interest indirectly and have a relevant interest (Rule 2). It does however have a relevant interest to the extent that part of its share capital is held by Signor A (ICTA88/S752A(4)) (Rule 3). ‘S’ remains at 90% while ‘P’ is 0.18 (0.2 x 0.9). The relevant interest is therefore 16.2% (i.e. 90% x 0.2 x 0.9).

Signor A

Signor A does not have a relevant interest in the controlled foreign company in that he is not a United Kingdom resident company, nor a related person nor does he have a direct interest in the controlled foreign company.

Total relevant interests are therefore:


Top Co10%
A Ltd2.25%
B Ltd71.55%
E Inc 16.2%
