Where can I find my tax code?

Look on your latest payslip, pension payslip or HMRC tax code notice. You can also find it in your Personal Tax Account. It is not your National Insurance number.

2 · Does it fit my situation?

Which income is this code for?

Expected pay from all jobs and private pensions

For 6 April 2026 to 5 April 2027. Include bonuses and all jobs, not just the one using this code. Enter 0 if you have no PAYE pay.

Which pay figure should I use?

Standard UK allowance for 2026/27. Special allowances, flat-rate suitability, K-code rounding, in-year collection and PAYE tax/refunds need the HMRC notice or payroll records. Pension/Gift Aid coding relief beyond the adjusted-income effect must be entered from the notice. Main-home selection is not a residence determination.
