Corporation tax is the tax a UK limited company pays on its taxable profits, currently charged at 19% for profits up to £50,000, 26.5% for profits between £50,000 and £250,000 and 25% for profits over £250,000 (all at 25% for non-trading companies). Green Accountancy prepares and files corporation tax returns for a wide range of companies, applying legitimate reliefs to minimise the amount owed.
