HMRC PAYE Tax Calculator is a free web tool for employers checking an employee’s Income Tax for a pay period in the current tax year. It is aimed at UK payroll checks, using the employee’s tax code, payment date, pay frequency and pay before deductions. It is an official government calculator rather than a commercial tax product, and its scope is employee PAYE rather than a broad estimate of annual tax or take-home pay.

The calculator supports weekly, fortnightly, four-weekly and monthly pay periods. Employers can also enter previous-period gross pay and tax due when relevant. HMRC’s guidance says the tool is updated for current tax-year rates, and the listed year is 2026 to 2027. That makes it suited to checking a specific pay period with payroll inputs to hand; it is not presented as a general-purpose calculator for other income sources or tax questions.

There is no charge to use it, and it runs on the web. Its narrow focus is useful when the task is PAYE employee Income Tax, but employers seeking annual tax projections or take-home-pay comparisons should choose a calculator built for those estimates instead. The right fit is a payroll check that follows UK PAYE inputs and pay periods, not a replacement for wider tax planning or a commercial payroll system.
