Understanding Your UK Tax Code

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.

At Calculator Site, we designed this tool to demystify your payslip. For the 2026/27 tax year, the most common code is 1257L, which corresponds to the standard personal allowance of £12,570. If your code is different, it might be because you have a second job, receive company benefits, or need to account for underpaid tax from a previous year. For more details, our Take-Home Pay Calculator provides another useful perspective.
