Your tax code is a crucial piece of information used by your employer to calculate the correct amount of income tax to deduct from your salary. It is provided by HM Revenue & Customs (HMRC) and is tailored to your personal circumstances. The numbers in your tax code usually represent the tax-free personal allowance you are entitled to, while the letters give your employer more information about your tax situation.
