Corporation Tax: tax avoidance involving carried-forward losses: effect where the rules apply
Any deductions arising as a consequence of the arrangements (and meeting condition B) will still be available under the normal rules. It is only the carried-forward reliefs that are denied, and only against the profits arising from the arrangement.
Company A has £5m of pre-1 April 2017 carried-forward non-trading loan relationship deficits. It enters an arrangement meeting the conditions in CTA10/s730G in order to access these losses.
The arrangement gives rise to £1m of additional non-trading profits in company A, whilst also giving rise to £1m of non-trading debits in company B, which is a connected company. In the absence of the arrangement company A would not have these £1m of profits, and company B would not have the non-trading debits in this accounting period.
CTA10/s730G(10) means that company A cannot use its carried-forward non-trading deficit against the £1m of non-trading profits arising from the tax arrangements. Assuming the debit arising from the tax arrangement gave rise to a surrenderable loss in company B, company B may be entitled to surrender the £1m of non-trading loan relationship deficit arising from the arrangements against it.
