1. What Are Tax Codes?

• Issued by HMRC: Your tax code is issued by HM Revenue & Customs (HMRC) and indicates how much tax-free income you're entitled to in a tax year.
• Format: It typically consists of numbers and letters (e.g., 1257L) and helps your employer calculate the correct amount of income tax to deduct.
• Importance: Having the correct tax code ensures you don’t pay too much or too little tax.
