How Much Tax Do You Actually Pay on Your Salary?
On a £40,000 salary in 2026/27, your income tax is £5,486. That is an effective rate of 13.7%, not the 20% basic rate you might expect. Income tax works in slices: each band applies only to the income that sits in that range, never to your whole salary.

The bands: your salary is taxed in slices
Every UK taxpayer gets a Personal Allowance: £12,570 of income that is completely tax-free in 2026/27. Above that, income is split into bands and each slice is taxed at the rate for that band only.
In England, Wales and Northern Ireland, there are three bands above the Personal Allowance:
2026/27 income tax bands (England, Wales and NI)
A higher-rate taxpayer earning £60,000 pays 20% on the slice between £12,571 and £50,270, and 40% only on the remaining £9,730. The 40% rate does not apply to the whole salary.
Effective rates at common salary points
The table below shows the gap between marginal rate (what you pay on your next pound) and effective rate (what proportion of your total income goes to HMRC). Figures are for England, Wales and Northern Ireland, income tax only, 2026/27.
| Salary | Income tax | Effective rate | Marginal rate |
|---|---|---|---|
| £25,000 | £2,486 | 9.9% | 20% |
| £35,000 | £4,486 | 12.8% | 20% |
| £50,000 | £7,486 | 15.0% | 20% |
| £60,000 | £11,432 | 19.1% | 40% |
| £80,000 | £19,432 | 24.3% | 40% |

Scotland: six bands, not three
Scottish taxpayers pay the same Personal Allowance, but income above it is split across six bands set each year by the Scottish Parliament rather than Westminster.
2026/27 Scottish income tax bands
Below £29,526, Scottish taxpayers pay slightly less income tax than those in England and Wales, because the 19% Starter rate is a point below the 20% basic rate. Above £43,662, that shifts: the Intermediate rate is 21% rather than 20%, and the Higher rate is 42% rather than 40%.
The Scotland vs England income tax guide compares the bill at eight salary points with 2026/27 figures. For your exact Scottish take-home, use the Scottish Income Tax calculator.
National Insurance: the second deduction
National Insurance (NI) is a separate deduction that sits alongside income tax on your payslip. In 2026/27, employees pay 8% on earnings between £12,570 and £50,270, then 2% on everything above that. NI thresholds are set by Westminster and apply across the whole UK, including Scotland.
The combined effect of income tax and NI on a £35,000 salary in England:
£35,000 salary — 2026/27 deductions (rUK)
Assumes 2026/27 rates, no pension deduction, no student loan. Your take-home may differ.
The combined effective rate on that salary is 18.0%. The income tax rate alone is 12.8%. Both numbers are correct; the difference is which deduction you are measuring. The take-home pay calculator shows all deductions together.
Reducing your tax bill
The most effective way to reduce the income tax you pay is to reduce your taxable income. Pension contributions are the main route for most employees. When you contribute, HMRC adds tax relief at your marginal rate, returning the tax you would have paid on that income.
Salary sacrifice
Your employer reduces your gross pay and pays the difference straight into your pension. Because the contribution comes out before tax and National Insurance are calculated, a basic-rate earner saves 28p per £1 contributed: 20% income tax relief plus 8% NI. For higher-rate and Scottish taxpayers the saving is larger. The salary sacrifice guide has the full worked examples.
Personal pension contributions
If your employer doesn't offer salary sacrifice, you can contribute to a personal pension (SIPP) and claim the relief yourself. Basic-rate relief (20%) is added automatically by your pension provider. Higher-rate and additional-rate taxpayers claim the extra through Self Assessment.
The £100,000 Personal Allowance trap
Once your income passes £100,000, HMRC begins withdrawing the Personal Allowance. The combined effect on the band from £100,000 to £125,140 is a 60% effective income tax rate (67.5% in Scotland). Pension contributions are the most effective way to avoid it. The 60% tax trap guide explains the mechanism and how much pension sacrifice brings you out of it.

Frequently asked questions
Do I pay 40% tax on my whole salary if I earn above £50,270?
No. The 40% higher rate applies only to the slice of your income above £50,270. Everything between your Personal Allowance (£12,570) and £50,270 is taxed at 20%. On a £60,000 salary in 2026/27, your income tax is £11,432, an effective rate of 19.1%, not 40%.
What is the Personal Allowance?
The Personal Allowance is the amount you earn before any income tax is due. For 2026/27, it is £12,570 for most UK taxpayers and is frozen at this level until 2030/31. If your income exceeds £100,000, HMRC begins to withdraw it: you lose £1 of allowance for every £2 earned above £100,000, and the allowance is gone entirely at £125,140.
How much income tax do I pay on a £30,000 salary?
On a £30,000 salary in England, Wales or Northern Ireland in 2026/27, your income tax is £3,486. You pay 20% on £17,430, the amount above your £12,570 Personal Allowance. Your effective income tax rate is 11.6%. In Scotland the bill is slightly lower because some of that income falls in the 19% Starter rate band.
Is income tax different in Scotland?
Yes. Scotland sets its own income tax rates and bands through the Scottish Parliament. Below about £29,526, Scottish taxpayers pay slightly less income tax than those in England and Wales. Above £43,662, Scottish rates are higher: 42% rather than the 40% higher rate in England. Use the Scottish Income Tax calculator to see your exact bill.
What is the difference between marginal rate and effective rate?
Your marginal rate is the percentage you pay on your next pound of income. Your effective rate is your total income tax bill divided by your total income. On a £60,000 salary, the marginal rate is 40% but the effective rate is 19.1%, because most of the income was taxed at 20% or not at all.
Do I pay National Insurance on top of income tax?
Yes. National Insurance (NI) is a separate deduction calculated alongside income tax. In 2026/27, employees pay 8% on earnings between £12,570 and £50,270, then 2% above that. The NI thresholds are the same across the whole UK, including Scotland. On a £35,000 salary, NI adds £1,794 on top of £4,486 in income tax, bringing the combined effective rate to 18%.
Understanding tax is one part of the picture. How you think about the money you keep is the other. Morgan Housel's book is the clearest account of the habits and biases that determine what people actually do with their income.
