Reporting your tax code as wrong
Tell HM Revenue and Customs (HMRC) if your tax code is wrong. YouÂll need your National Insurance number and your PAYE reference – you can find these on your payslip.
Tell HMRC your tax code is wrong at the HMRC website. You’ll need your PAYE coding notice.
You can also telephone HMRC.
