ICTA88/S776 does not apply to a gain by an individual from the
disposal of a private residence that is exempt from Capital Gains
Tax by virtue of the only/main residence rules at
TCGA92/S222-TCGA92/S226 (ICTA88/S776 (9).
Nor does it apply where the gain would have been exempt under
those provisions but for TCGA92/S224 (3) (residences acquired
partly with a view to make a gain).
