I’ve seen the term Tax Reference Number mentioned on several official tax documents but I’m not entirely sure what it means. Can someone explain what a Tax Reference Number is and how it’s used for filing taxes or dealing with tax authorities? Also, where can I find my Tax Reference Number on payslips or HMRC correspondence? Is it the same as a UTR (Unique Taxpayer Reference) or something different? A clear explanation of the Tax Reference Number and its role in tax identification would really help.
