The Supreme Court in ScottishPower (SCPL) Ltd and others v HMRC [2026] UKSC 35, has held that redress payments, made by the taxpayer under voluntary settlement agreements with the energy regulator in lieu of regulatory penalties, had the character of penalties and were non-deductible on the grounds that although the redress payments were paid in the ‘course’ of the trade, they were not paid wholly and exclusively for the ‘purposes’ of the taxpayer’s trade, i.e. for the purposes of earning profits.
The decision overturns the earlier judgment of the Court of Appeal. It provides important clarification on the rationale for penalties being treated as non-deductible for tax purposes and, in so doing, significantly extends the scope of what is meant by ‘penalty’ in this context.
The decision will be of particular interest to businesses operating in regulated sectors, however the principles discussed will have broader relevance to any situation in which a taxpayer incurs expenditure which may be regarded as a punishment – including under some settlement arrangements.
