What this leaves out or assumes
- Worked out for the whole year, as payroll does when you're paid the same each month. An emergency code works each payday on its own, which can give a different total.
- Income Tax only: National Insurance and student loans also come off your pay.
Where the figures come from
- Higher rate of Income Tax (England, Wales and Northern Ireland): 40%. Source: HMRC: Rates and thresholds for employers 2026 to 2027. Checked 13 November 2026.
