  • Income Tax Calculation error

    Good morning, I have been sent an email saying that I have had a Tax Code change. When I access the HMRC web page to check this change, it says I have not payed enough Income Tax for the previous tax year, and that I owe £2000. However, when I try to check how much Income Tax I paid last year (between 6th April 2021 and 5th April 2022), I am told that HMRC "cannot calculate your tax yet as we are still waiting for information to reach us". How is this possible? I have been checking al my payslips and I do not think I have underpayed Income Tax and that this must be an error, however, the first thing HMRC does is changing my Tax Code when they do not even know how much Income Tax I have paid! I would appreciate some help as to how to proceed. Regards, Alfonso
