What is the PAYE Tax System?

Introduction to PAYE

The Pay As You Earn (PAYE) system is the standard method for collecting income tax and National Insurance contributions from employees’ salaries in the United Kingdom. Under PAYE, employers deduct tax and NI from wages before they are paid to the employee and send it directly to HMRC.

Purpose of PAYE

The PAYE system ensures that taxes are collected regularly and in real-time, reducing the risk of underpayment or overpayment at the end of the tax year. It is used by almost all employers across the UK.

Income Tax in the UK

Income Tax Bands for 2024–25

The UK has a tiered income tax system. For the tax year 2024–2025, the tax bands are:

Band Taxable Income Tax Rate
Personal Allowance Up to £12,570 0%
Basic Rate £12,571 to £50,270 20%
Higher Rate £50,271 to £125,140 40%
Additional Rate Over £125,140 45%

Personal Allowance Explained

Everyone is entitled to a tax-free personal allowance unless your income exceeds £100,000. For incomes over £100,000, the allowance tapers down by £1 for every £2 earned above that threshold, and is fully removed at £125,140.

Income Tax Example Calculation

If your salary is £60,000:

  • First £12,570 is tax-free
  • Next £37,700 taxed at 20% = £7,540
  • Remaining £9,730 taxed at 40% = £3,892
  • Total Income Tax = £11,432

National Insurance Contributions (NICs)

What is National Insurance?

National Insurance contributions fund state benefits like the State Pension, maternity allowance, and unemployment support. Employees pay Class 1 contributions.

NIC Rates for 2024–25

Band Weekly Income NI Rate
Primary Threshold Up to £242/week 0%
Main Rate £242.01 to £967/week 8%
Upper Earnings Limit Over £967/week 2%

NIC Example

For a salary of £60,000/year:

  • NI threshold: £12,570
  • Income between £12,570–£50,270 at 8% = £3,016
  • Income over £50,270 at 2% = £194
  • Total NI = £3,210

Calculating Net Take-Home Pay

Step-by-Step Guide

  1. Start with Gross Salary: e.g., £60,000
  2. Subtract Personal Allowance: £12,570
  3. Apply Tax Bands: Calculate based on the band split
  4. Calculate NI: As per the thresholds
  5. Subtract Tax + NI from Gross
  6. Result = Take-Home Pay

PAYE Tax Codes

What is a Tax Code?

A tax code is used by your employer to work out how much tax to deduct. It reflects your personal allowance and any adjustments (e.g., unpaid tax, benefits).

Common Tax Codes

Code Meaning
1257L Standard personal allowance
BR Basic rate on all income
D0 All income taxed at 40%
D1 All income taxed at 45%
K You owe tax from earlier periods

How Tax Codes Affect PAYE Calculations

If your tax code is incorrect, your PAYE deductions could be wrong. Always check your tax code on your payslip.

PAYE for Different Work Situations

Full-Time Employees

Most straightforward PAYE setup. Your employer deducts tax and NI before paying your net salary.

Part-Time and Zero-Hour Workers

PAYE still applies if you earn over the personal allowance. You may end up with multiple tax codes if you have more than one job.

Self-Employed Individuals

Self-employed individuals use the Self Assessment system rather than PAYE, though they can use similar calculators to estimate tax liability.

Contractors Using Umbrella Companies

Umbrella companies process your pay through PAYE, including all tax and NI deductions. It’s essential to use calculators to verify what you should be paid.

Additional Considerations

Student Loan Repayments

These are deducted through PAYE if you earn above the threshold:

  • Plan 1: £24,990/year (9%)
  • Plan 2: £27,295/year (9%)
  • Plan 4 (Scotland): £27,660/year (9%)
  • Postgraduate Loan: £21,000/year (6%)

Workplace Pension Contributions

Auto-enrolment means employees contribute to a pension scheme. Typically:

  • Employee: 5%
  • Employer: 3%

This affects your take-home pay and should be considered in PAYE calculators that support pension input.

Benefits in Kind

Company car, private health insurance, and other perks are taxable and influence your tax code and deductions.

How to Use a PAYE Tax Calculator

  • Tax code (optional)
  • Student loan status
  • Pension contributions

Output Breakdown

  • Income tax
  • NI contributions

Interpreting Results

Common Mistakes to Avoid

Not Updating Tax Codes

If your circumstances change (e.g., new job, benefits, marriage), inform HMRC to update your tax code.

Overlooking Pension Contributions

Net take-home calculators must factor in auto-enrolled pensions.

Using Annual Instead of Monthly Values

Ensure you match the calculator’s input format — if it expects annual salary, do not input monthly.
