How the 2026/27 estimate works
The calculator applies the £12,570 standard Personal Allowance, reduces that allowance by £1 for every £2 of adjusted income above £100,000, then applies the 20%, 40% and 45% main Income Tax rates used in England, Wales and Northern Ireland. It separately estimates standard category-A employee National Insurance.
What is not included?
Student loans, benefits in kind, unusual tax codes, Scottish Income Tax, pension tax relief details and other payroll adjustments are not automatically included. Use the dedicated tools for those cases.
Why annual payroll can differ
PAYE and National Insurance are operated through payroll periods, so this annualised planning estimate may not match a payslip to the penny.

Planning estimate only. Payroll can differ because PAYE and National Insurance are normally calculated per pay period and can depend on tax code, category letter and individual circumstances.
