PAYE codes, also known as tax codes, are essential for determining how much income tax is deducted from an employee’s salary under the Pay As You Earn (PAYE) system. Issued by HM Revenue and Customs (HMRC), these codes help employers calculate the correct amount of tax to withhold from each paycheck. Misunderstanding or misapplying PAYE codes can lead to underpayment or overpayment of tax, making it crucial for both employers and employees to understand how these codes work, how they are assigned, and what to do if they are incorrect. This guide explores PAYE codes in detail, covering their structure, common codes, and the responsibilities associated with managing them.
1. What Is a PAYE Code?
