How this annual Income Tax estimate works
The calculation deducts the standard Personal Allowance from annual income, tapers that allowance above GBP 100,000 where applicable, and applies the 2026/27 tax bands for the selected jurisdiction. Income already reported as taxable after allowance should not be entered here, or the allowance would be counted twice.
Formula explained
Tax estimate logic
This calculator applies a simple UK tax-band structure so users can test annual income scenarios quickly before moving into deeper payroll calculations.
Formula
Tax = 20% basic band + 40% higher band + 45% additional band
