PAYE is how HMRC collects tax from employment
PAYE stands for Pay As You Earn. It's HMRC's system for collecting Income Tax and National Insurance from most employment income. Instead of you paying tax separately, your employer or pension provider works it out and deducts it before you're paid.
What your employer actually does
Payroll software calculates how much Income Tax and National Insurance to take from each payment, using the tax code HMRC has issued for you. See our guide to understanding UK tax codes for what that code means. Your employer then sends the amount deducted to HMRC and pays you the rest.
Why one payslip can look different from another
PAYE normally works on a cumulative basis, spreading your tax-free Personal Allowance evenly across the year. If one pay period is unusually high or low, because of overtime, a bonus, or a change in hours, that period's tax can look disproportionate on its own, even though it typically evens out over the rest of the tax year.
Why your payslip might not match an annual estimate
An annual estimate like WageOra's assumes a steady salary across the whole tax year. Your actual payslip reflects one specific pay period, using your own tax code and payroll timing. See why your payslip can differ from a salary calculator for the full list of reasons and what to check.
If something looks wrong
GOV.UK has a tool to check if the tax on your payslip is correct. For anything specific to your own pay, such as your exact tax code, deductions or payroll settings, your employer's payroll or HR team can see details that WageOra has no access to.

The Salary Calculator estimates your take-home pay for the 2026/27 tax year using WageOra's shared tax engine. See How WageOra Works for how it's calculated. This is an estimate, not personalised tax advice.
