Quick answer:
PAYE stands for Pay As You Earn. It is the standard system used to collect Income Tax and National Insurance contributions (NICs) directly from an employee’s wages or pension before they are paid.
If you have ever looked at your wage slip and wondered what is PAYE on payslip, you are not alone. It is one of the most searched payroll questions in the UK. PAYE is the system HMRC uses to collect Income Tax from employment income, while employee National Insurance is calculated and deducted separately through payroll.
Your employer calculates the relevant deductions through payroll and reports them to HM Revenue and Customs (HMRC). Therefore, tax is generally deducted before you receive your wages.
This guide explains exactly what PAYE means on your payslip, how it’s calculated, and what to do if something looks wrong.

What Is PAYE on Payslip?
PAYE on a payslip shows how much Income Tax your employer has deducted from your gross pay and sent to HMRC on your behalf.
Generally, National Insurance (NI) is shown as a separate deduction. Your tax code helps your employer calculate how much Income Tax to deduct, while your earnings and circumstances affect the amount you pay.
PAYE Meaning on a Payslip Explained
The PAYE amount on your payslip depends on several factors:
- Your tax code: HMRC uses tax codes to help your employer calculate how much Income Tax to deduct.
- Your taxable pay: Your earnings and any applicable adjustments affect how much tax you owe.
- Tax rates and allowances: The relevant rates and allowances determine the Income Tax due.
Moreover, your employer calculates deductions through payroll and reports the required information to HMRC using Real Time Information (RTI). This is why two employees with the same gross salary may have different take-home pay and Income Tax deductions because of differences in their tax codes, taxable benefits, pension arrangements and other circumstances.
Why Employers Use PAYE Deductions on Payslips?
If you are wondering why employers use PAYE, you should know that PAYE not only allows HMRC to collect Income Tax but also NICs from employment income throughout the year. Employers must register for PAYE when the relevant conditions apply and report employees’ pay and deductions to HMRC through RTI, usually on or before each payday.
How Is PAYE Tax on Payslip Calculated?
Now that you understand what PAYE is on a payslip, let’s discuss how to calculate it.
For the 2026/27 tax year, the rates for England, Wales, and Northern Ireland are:
- Personal Allowance: £12,570 (0% tax): frozen until April 2031
- Basic Rate: 20% on income from £12,571 to £50,270
- Higher Rate: 40% on income from £50,271 to £125,140
- Additional Rate: 45% on income above £125,140
Remember that Scotland uses a separate six-band system, with rates ranging from 19% to 48%, and Welsh rates currently mirror the rest of the UK.
Worked Example of PAYE Tax on Payslip
Here’s a simple example of how PAYE tax is calculated for someone earning £35,000 a year on the standard 1257L tax code:
| Step | Calculation | Result |
| Personal Allowance | 1257 × £10 | £12,570 |
| Taxable income | £35,000 − £12,570 | £22,430 |
| Tax owed (basic rate) | £22,430 × 20% | £4,486.00 |
So, this gives an estimated average of £373.83 in Income Tax per month. The actual PAYE deduction on a payslip may differ because payroll calculations depend on your pay period, tax code, and whether your code is applied cumulatively or on a Week 1/Month 1 basis.
What Does an Emergency Tax Code Mean on a Payslip?
An emergency tax code may be used when HMRC lacks the information needed to calculate your Income Tax correctly. For example, when you start a new job without a P45, you may get an emergency tax code.
Emergency tax code examples include 1257L W1, 1257L M1 and 1257L X. These indicate non-cumulative tax treatment. This means tax is generally calculated using your pay for that period rather than your total pay and tax for the year so far. An emergency code does not automatically mean you have overpaid tax.
What Is the Difference Between PAYE and National Insurance?
While understanding what PAYE on a payslip is, people often confuse PAYE and NI. Note that PAYE and NI are related to payroll, but they are not the same deduction.
PAYE Income Tax is calculated using your tax code and applicable Income Tax rates. In contrast, employee NI is calculated separately, using the relevant earnings thresholds and contribution rates.
For most employees under the standard Class 1 rules in 2026/27, employee NI is typically charged at 8% on earnings between the primary threshold and upper earnings limit, and 2% on earnings above the upper earnings limit.
Moreover, your payslip may show pension contributions, student loan repayments or other deductions. These should not be confused with PAYE Income Tax.
Will I Automatically Get a Refund if I Have Overpaid PAYE?
Not necessarily. If you have overpaid Income Tax through PAYE, HMRC may correct your tax code during the year or review your tax position after the tax year ends. If HMRC identifies an overpayment, it may issue a P800 tax calculation explaining how to receive your refund. Depending on the instructions in the letter, you may need to claim the refund online, through your Personal Tax Account or HMRC app, or wait for a cheque.
If you think your tax deductions are incorrect, check your tax code and contact HMRC where necessary.
What Are the Common Mistakes with PAYE on Payslips?
Several recurring issues trip up both employees and employers when it comes to PAYE:
- Ignoring tax code changes: A wrong code can mean months of overpaying or underpaying tax.
- Not checking payslips after changing a job: You may be on an emergency tax code.
- Overlooking the £100,000 taper: Adjusted net income above £100,000 reduces the £12,570 Personal Allowance by £1 for every £2 earned above that level. It reaches zero at £125,140.
- Confusing PAYE with total deductions: PAYE is only the Income Tax line, not National Insurance, pension, or student loan repayments.
- Employers missing RTI deadlines: Late Full Payment Submissions may trigger automatic HMRC penalties.
What Are the Best Practices for Checking Your PAYE Deduction
To make sure your PAYE deduction on your payslip is correct, follow these instructions:
- Check that the tax code on your payslip matches the latest tax code information from HMRC. You can review your tax details through your Personal Tax Account and compare them with your P45 or P60 where relevant.
- Use HMRC’s online tax checker if you have more than one job or pension
- Review your payslip every time you receive a pay rise, bonus, or benefit change.
- Contact HMRC promptly if your code looks wrong.
- Keep your payslips and P60s for your records.
