UK Take-Home Pay Explained — Income Tax, National Insurance and Your Payslip
If you’ve ever looked at your payslip and wondered why your take-home pay is so much less than your salary, you’re not alone. Understanding how UK income tax and National Insurance work can feel complicated — but once you know the basics, it all makes sense. This guide explains exactly what gets deducted from your pay, how the tax bands work and how to calculate your take-home pay for any salary.
How Much Tax Do You Pay in the UK?
The amount of income tax you pay depends on how much you earn. The UK uses a banded tax system — meaning different portions of your income are taxed at different rates. You never pay the higher rate on your entire salary, only on the portion that falls within each band.
| 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% |
What Is the Personal Allowance?
The Personal Allowance is the amount you can earn before paying any income tax. In 2025/26 this is £12,570. So if you earn £30,000 per year, you only pay income tax on £17,430 — the amount above your Personal Allowance.
One important exception — if you earn over £100,000 your Personal Allowance starts to reduce. For every £2 you earn above £100,000, your Personal Allowance reduces by £1. By the time you earn £125,140 the Personal Allowance disappears entirely, meaning there is effectively a 60% marginal tax rate between £100,000 and £125,140.
What Is National Insurance?
National Insurance (NI) is a separate deduction from income tax. It funds state benefits including the NHS, state pension and unemployment support. As an employee you pay Class 1 National Insurance contributions on your earnings.
| Earnings | NI Rate |
|---|---|
| Up to £12,570 | 0% |
| £12,571 to £50,270 | 8% |
| Over £50,270 | 2% |
How to Calculate Your Take-Home Pay
Here is a step by step example for someone earning £35,000 per year in England:
| Item | Amount |
|---|---|
| Gross Salary | £35,000 |
| Less Personal Allowance | £12,570 |
| Taxable Income | £22,430 |
| Income Tax (20%) | £4,486 |
| National Insurance (8%) | £1,796 |
| Total Deductions | £6,282 |
| Take-Home Pay | £28,718 per year / £2,393 per month |
Does Scotland Have Different Tax Rates?
Yes — Scotland has its own income tax rates set by the Scottish Parliament. Scottish taxpayers pay slightly different rates on earnings between the Personal Allowance and £50,270. National Insurance rates are the same across the whole UK.
| Band | Taxable Income | Scottish Rate |
|---|---|---|
| Starter Rate | £12,571 to £14,876 | 19% |
| Basic Rate | £14,877 to £26,561 | 20% |
| Intermediate Rate | £26,562 to £43,662 | 21% |
| Higher Rate | £43,663 to £75,000 | 42% |
| Top Rate | Over £125,140 | 48% |
What Other Deductions Might Appear on My Payslip?
Beyond income tax and National Insurance, several other deductions may appear on your payslip depending on your circumstances:
- Pension contributions — if your employer has enrolled you in a workplace pension, contributions are deducted automatically. The minimum employee contribution is 5% under auto-enrolment rules
- Student loan repayments — deducted automatically once you earn above the threshold. Plan 1 threshold is £24,990, Plan 2 is £27,295 and Plan 4 (Scotland) is £31,395
- Child Benefit tax charge — if you or your partner earn over £60,000 and claim Child Benefit, a tax charge may apply
- Salary sacrifice schemes — some employers offer cycle to work, childcare vouchers or electric vehicle schemes where contributions come from your gross salary before tax

Frequently Asked Questions
Why is my take-home pay different from the examples?
The examples above use a standard 1257L tax code with no pension contributions or student loan deductions. Your take-home may differ if you have a different tax code, contribute to a workplace pension, are repaying a student loan or have any other deductions.
What is a tax code and why does it matter?
Your tax code tells your employer how much Personal Allowance to apply to your salary. The most common code is 1257L which gives you the standard £12,570 Personal Allowance. If your code is different — for example if you have unpaid tax from a previous year — your take-home pay will be lower.
How do I know if I'm on the right tax code?
Your tax code appears on your payslip and on your P60. If you think your tax code is wrong contact HMRC directly on 0300 200 3300 or check your Personal Tax Account at gov.uk.
What is the difference between gross and net pay?
Gross pay is your salary before any deductions. Net pay is what you actually receive after income tax, National Insurance and any other deductions have been taken. Net pay is your take-home pay.
Do I pay National Insurance on all my earnings?
No — you only pay National Insurance on earnings above £12,570 per year. You pay 8% on earnings between £12,570 and £50,270, and 2% on anything above £50,270.
