What this comparison does
It applies the same salary, tax code and loan settings to verified 2025/26 and 2026/27 annual PAYE rules for England, Wales and Northern Ireland. This makes it easier to see whether a change in net pay is caused by a salary change or by payroll thresholds.
Important limitations
It is an annual estimate, not a recreation of an individual historic payslip. Pension contributions, bonuses, benefits, cumulative tax adjustments and employer-specific deductions are not included. Scottish tax comparisons will be added when the historical Scottish ruleset is separately validated.
The rules come from HMRC's 2025/26 and 2026/27 employer rates and thresholds.
