How PAYE is Calculated in the UK: Complete 2024/25 Guide
Understanding how PAYE (Pay As You Earn) is calculated in the UK is essential for every employee to ensure you’re paying the correct amount of tax and National Insurance. This comprehensive guide explains the PAYE system, tax codes, thresholds, and how your take-home pay is determined.
What is PAYE?
PAYE is HM Revenue and Customs’ (HMRC) system to collect Income Tax and National Insurance from your employment income. Your employer deducts these before paying your wages, ensuring you meet your tax obligations throughout the year.
Key Components of PAYE Calculations
- Taxable Income – Your salary minus your Personal Allowance (£12,570 for 2024/25)
- Income Tax Bands – Different rates apply to portions of your income
- National Insurance Contributions (NICs) – Separate from Income Tax
- Pension Contributions – Reduce your taxable income
- Student Loan Repayments – If applicable

National Insurance Contributions (NICs) 2024/25
NICs are separate from Income Tax and fund state benefits like the State Pension. The rates for 2024/25 are:
| Class | Weekly Earnings | Rate | Annual Equivalent |
|---|---|---|---|
| Class 1 (Primary) | £242 to £967 | 8% | £12,570 to £50,270 |
| Class 1 (Primary) | Over £967 | 2% | Over £50,270 |
| Class 1 (Secondary) | Over £175 | 13.8% | Over £9,100 |
How Your Tax Code Affects PAYE
Your tax code determines how much tax-free income you receive. The standard code for 2024/25 is 1257L, meaning you can earn £12,570 tax-free. Other common codes include:
- 1257M – Receiving Marriage Allowance
- BR – Basic Rate (no Personal Allowance)
- D0 – Higher Rate (no Personal Allowance)
- D1 – Additional Rate (no Personal Allowance)
- K Codes – Tax owed from previous years
Student Loan Repayments Through PAYE
If you have a student loan, repayments are automatically deducted through PAYE once you earn over the threshold:
- Plan 1 (pre-2012): 9% on earnings over £22,015
- Plan 2 (post-2012): 9% on earnings over £27,295
- Plan 4 (Scotland): 9% on earnings over £27,660
- Postgraduate Loan: 6% on earnings over £21,000
Pension Contributions and Tax Relief
Pension contributions reduce your taxable income through tax relief. There are two main types:
- Relief at Source – Your pension provider claims 20% tax relief (common for workplace pensions)
- Net Pay Arrangement – Contributions are taken before tax (common for public sector pensions)
For 2024/25, the annual allowance is £60,000 (or your earnings if lower), and the lifetime allowance was abolished in April 2024.
PAYE for Different Payment Frequencies
PAYE calculations adjust based on how often you’re paid:
- Weekly: Tax thresholds divided by 52
- Monthly: Tax thresholds divided by 12
- Yearly: Full annual thresholds apply
Your employer uses cumulative tax codes to ensure you pay the correct amount over the year, adjusting for any under/overpayments.
Common PAYE Issues and How to Fix Them
Mistakes can happen with PAYE. Here’s how to resolve common problems:
- Wrong Tax Code – Contact HMRC or check via your Personal Tax Account
- Overpaid Tax – Claim a refund through HMRC (usually automatic via P800)
- Underpaid Tax – HMRC will adjust your tax code or send a bill
- Emergency Tax – Temporary code (e.g., 1257 W1/M1) used when HMRC lacks details
PAYE for Self-Employed and Side Income
If you’re employed but have self-employed income over £1,000, you must:
- Register for Self Assessment by 5 October
- File a tax return by 31 January
- Pay any tax owed by 31 January
HMRC may adjust your PAYE tax code to collect self-employed tax through your wages.
PAYE and Benefits in Kind
Non-cash benefits (e.g., company car, private health insurance) are taxable. Your employer reports these via P11D forms, and the value is added to your taxable income, adjusting your tax code.
How to Check Your PAYE Deductions
Always verify your payslip for:
- Correct tax code
- Accurate taxable pay (gross pay minus allowances)
- Proper National Insurance deductions
- Any student loan or pension deductions
Use HMRC’s Income Tax Calculator to verify your deductions.
PAYE for High Earners (Over £100,000)
If you earn over £100,000:
- Your Personal Allowance reduces by £1 for every £2 earned over £100,000
- At £125,140, you lose the Personal Allowance entirely
- You may need to complete a Self Assessment tax return
PAYE and Marriage Allowance
If you’re married or in a civil partnership and one partner earns less than £12,570, you can transfer 10% of their Personal Allowance (£1,260) to the higher earner, saving up to £252 in tax. Apply via GOV.UK.
PAYE for Directors and Company Owners
Company directors often use a combination of:
- Small salary (up to National Insurance threshold)
- Dividends (taxed separately)
This is tax-efficient but requires careful PAYE operation through the company payroll.
Recent Changes to PAYE (2024/25)
Key updates for the 2024/25 tax year:
- National Insurance cuts: Primary Class 1 reduced from 10% to 8% (January 2024)
- Frozen thresholds: Personal Allowance and higher-rate threshold remain at 2023/24 levels until 2028
- Student loan thresholds: Plan 2 threshold increased to £27,295
- Pension changes: Lifetime allowance abolished, annual allowance increased to £60,000
PAYE for Non-Residents and Expats
If you’re not UK-resident but work in the UK:
- You’ll typically pay UK tax on UK earnings
- Double taxation agreements may apply
- Special rules exist for seafarers and oil/rig workers
Check HMRC’s guidance for non-residents.
How to Appeal PAYE Decisions
If you disagree with HMRC’s PAYE calculation:
- Contact HMRC within 30 days of the decision
- Provide evidence (e.g., P60, payslips)
- If unresolved, escalate to a tax tribunal
Use HMRC’s complaints procedure for formal appeals.
PAYE and Universal Credit
Your PAYE income affects Universal Credit payments:
- Earnings are reported via Real Time Information (RTI)
- Universal Credit adjusts monthly based on your pay
- The work allowance lets you earn £370/month (or £630 with housing costs) before deductions
Future of PAYE: Digital Transformation
HMRC is modernising PAYE through:
- Making Tax Digital (MTD) for Income Tax (from April 2026)
- Real-Time tax code adjustments via digital platforms
- AI-driven compliance checks to reduce errors
Employers and employees will need to adapt to more frequent digital reporting.
Frequently Asked Questions About PAYE
Why has my tax code changed?
HMRC adjusts your tax code when:
- You receive a pay rise or bonus
- You start/stop receiving benefits in kind
- You claim Marriage Allowance
- HMRC corrects a previous error
Can I reduce my PAYE tax?
Legitimate ways to reduce PAYE include:
- Increasing pension contributions
- Claiming work-related expenses
- Donating to charity via Gift Aid
- Using salary sacrifice schemes (e.g., childcare vouchers)
What’s the difference between PAYE and Self Assessment?
PAYE is for employees, with tax deducted at source. Self Assessment is for self-employed individuals or those with complex tax affairs, requiring annual tax returns.
How do I get a P60?
Your employer must provide a P60 by 31 May after the tax year ends (5 April). It shows your total pay and deductions for the year. Keep it for tax records or mortgage applications.
What if I have two jobs?
HMRC will:
- Allocate your Personal Allowance to one job (usually the higher-paying one)
- Apply a BR (Basic Rate) or D0 (Higher Rate) code to your second job
- You may need to complete a Self Assessment if you earn over £100,000
How does PAYE work for bonuses?
Bonuses are taxed through PAYE as normal income. Your employer may:
- Add the bonus to your regular pay and tax it together
- Use a separate tax code (e.g., 0T) for the bonus
This can sometimes result in higher temporary deductions, corrected via your tax code later.
Expert Tips for Managing Your PAYE
- Check your tax code annually – Especially after life changes (marriage, new job, etc.)
- Use HMRC’s app – Track your tax in real-time
- Keep payslips – Essential for disputes or mortgage applications
- Review P60/P11D forms – Verify end-of-year totals
- Claim tax reliefs – For work expenses, charitable donations, etc.
