Companies in the United Kingdom with the highest income tax expense

Income tax expense is the tax a company charged against profit in its income statement for the year. It is not the same as the cash it handed to tax authorities: deferred tax, provisions and timing differences separate the two, often by billions. The cash figure is a different line in the cash-flow statement. Figures are for fiscal year 2025 and are read directly from each company's SEC filings; the source column on every row links to the document.
