PAYE Income Tax Calculator
Work out PAYE Income Tax for a pay period the way payroll software does: free pay for the period, taxable pay to date and tax due to date.
PAYE Income Tax Calculator
Built using UK PAYE and HMRC payroll rules for the 2026/27 tax year. Estimate only — not an official payroll record.
Figures are estimates produced by our shared payroll engine using published UK PAYE, National Insurance and student loan rules. They are not official payroll records and must not be used as evidence of pay. HMRC RTI integration is in development and testing.
Running payroll for real employees?
Our employer payroll system stores your employees, calculates each payroll run and produces finalised payslips from the stored payroll record — never from a re-run of the calculator.
Which tax codes are supported?
Standard L codes, K codes with the 50% regulatory limit, BR, D0, D1, 0T and NT, plus S (Scotland) and C (Wales) prefixes and W1/M1/X markers.
Why does the tax differ from annual tax divided by 12?
PAYE is not annual tax divided by twelve. It is worked out cumulatively across the tax year, which is exactly how this calculator and our payroll engine do it.
Does it include National Insurance?
Use the National Insurance calculator for employee NI and the Employer NI calculator for the employer's contributions.
