  • Interest on tax return

    I have been sent an email about claiming extra tax from the last financial year, however to does not not include the interest that HMRC has set out (4.5%, 1% under the base rate), however I found this on HMRC's webpage https://www.gov.uk/government/publications/rates-and-allowances-hmrc-interest-rates-for-late-and-early-payments/rates-and-allowances-hmrc-interest-rates#current-late-payment-and-repayment-interest-rates
