Key facts
- Personal allowance: £12,570 (frozen until April 2031)
- Basic rate: 20% on taxable income £12,571 to £50,270
- Higher rate: 40% on income £50,271 to £125,140
- Effective 60% marginal rate on income between £100,000 and £125,140
How the UK Income Tax Bands Work
Many people believe a pay rise can leave them worse off because "they moved into the 40% bracket." This is a myth. The UK uses a progressive, banded system. You never pay the higher rate on your entire income. You pay it only on the portion of income that falls within that band.
Here is how income is taxed for 2026/27 in England, Wales, and Northern Ireland:
| Band | Taxable Income | Rate |
|---|---|---|
| Personal allowance | £0 to £12,570 | 0% |
| Basic rate | £12,571 to £50,270 | 20% |
| Higher rate | £50,271 to £125,140 | 40% |
| Additional rate | Above £125,140 | 45% |
Source: HMRC, Income Tax rates and Personal Allowances, 2026/27.
So if you earn £55,000, you do not pay 40% on all £55,000. You pay 0% on the first £12,570, 20% on the next £37,700 (from £12,571 to £50,270), and 40% on just £4,730 (the slice from £50,271 to £55,000). Your total income tax comes to approximately £9,432, giving an effective rate of 17.1%, not 40%.

The Frozen Threshold Problem: Fiscal Drag Explained
The personal allowance and higher rate threshold have been frozen at their current levels since April 2022. The freeze now runs until April 2031, a nine-year hold. This is not a minor technicality. It is one of the largest stealth tax rises in modern UK history.
When salaries rise due to inflation or promotions but thresholds stay still, more of your income gets pushed into taxable territory. The Office for Budget Responsibility (OBR) estimates the freeze will:
- Pull an additional 5.2 million people into paying income tax by 2031
- Push 4.8 million more workers into the higher rate band by 2031
- Raise an extra £55.5 billion for the Treasury in 2030/31 alone
If the personal allowance had risen with CPI inflation since 2021/22, it would be approximately £14,800 in 2026/27. Instead, it sits at £12,570. That £2,230 gap is taxed at 20% for basic rate payers, costing each affected worker around £446 extra per year compared to indexed thresholds.
Expert Tip
If your salary has risen by 15% since 2022 but your take-home has barely moved, frozen thresholds are the primary reason. The basic rate band has not moved from £50,270 since 2021. In real purchasing-power terms, you are paying significantly more tax than you were four years ago even if the stated rates look the same.The £100,000 Tax Trap: A 60% Effective Rate
The most punishing point in the UK tax system sits between £100,000 and £125,140. In this band, your personal allowance is withdrawn at the rate of £1 for every £2 earned above £100,000. At £125,140, the full £12,570 allowance is gone.
This creates an effective marginal rate of 60% on income in this range. Every £1,000 extra you earn between £100,000 and £125,140 leaves you with just £400 after tax and National Insurance.
Why Does the 60% Rate Occur?
If you earn £101,000, you lose £500 of your personal allowance. That £500 becomes taxable at 40%, generating an extra £200 in tax. On top of the standard 40% rate, you effectively pay 60% on each pound in this band.

Scotland: A Different System
Scottish taxpayers pay Scottish income tax rates on non-savings, non-dividend income. Scotland operates a six-band system for 2026/27:
| Band | Income | 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% |
| Advanced rate | £75,001 to £125,140 | 45% |
| Top rate | Above £125,140 | 48% |
Scottish taxpayers earning between £43,663 and £50,270 pay 42% instead of 40%, and those earning above £75,000 face a 45% rate before reaching the additional rate threshold. This makes Scotland's tax burden notably higher for workers earning above £43,663. Savings and dividend income are still taxed at UK-wide rates.
How to Legally Reduce Your Income Tax Bill
There are several HMRC-approved methods to reduce your taxable income:
- Pension contributions: Money paid into a registered pension scheme reduces your adjusted net income. A basic rate taxpayer contributing £100 to their pension via salary sacrifice saves £20 in income tax and £8 in National Insurance. See the Salary Sacrifice Calculator for your specific figures.
- Gift Aid donations: Donations to registered charities under Gift Aid extend your basic rate band by the grossed-up amount. A higher rate taxpayer donating £1,000 can claim an additional £250 in tax relief through self-assessment.
- Marriage Allowance: If your partner earns below £12,570, they can transfer £1,260 of their unused allowance to you, saving up to £252 per year. You can backdate this claim for up to four years.
- Work expenses: Professional subscriptions, union fees, and qualifying work-from-home costs may be deductible. These are usually reflected in your tax code rather than claimed separately.
Expert Tip
If your salary pushes close to £50,270 or £100,000, even a small pension contribution can drop you into a lower effective band. For someone earning £52,000, contributing £2,000 gross into a pension (costing £1,600 net of basic rate relief) moves £2,000 out of the higher rate band, saving £800 in tax on top of the £400 basic rate relief already received. That is a 60% effective relief rate on the contribution.Income Tax Calculator

No. The personal allowance remains at £12,570, frozen since 2021/22 and confirmed frozen until at least April 2031 under the Autumn Budget 2025.
The basic rate is 20%, charged on taxable income between £12,571 and £50,270 for residents of England, Wales, and Northern Ireland.
Any gross salary above £50,270 pushes the income above that figure into the 40% higher rate. With average UK wages rising each year against frozen thresholds, increasing numbers of full-time workers now pay higher rate tax.
Fiscal drag occurs when tax thresholds are frozen while wages and prices rise. More income becomes taxable without any change to the stated tax rates. The OBR estimates the freeze from 2022 to 2031 will pull 5.2 million additional people into paying income tax.
Subtract your personal allowance (£12,570 for most people) from your gross income, then apply the band rates to the resulting taxable income. Or use the WhatsUK Income Tax Calculator for an instant result including National Insurance.
The additional rate of 45% applies to taxable income above £125,140 in England, Wales and Northern Ireland. At this income level the personal allowance is fully withdrawn.
Between £100,000 and £125,140 your personal allowance is withdrawn at £1 for every £2 earned, creating an effective marginal rate of 60% when combined with the 40% higher rate. Pension contributions or Gift Aid can bring adjusted net income back below £100,000.
Yes. Scotland uses six income tax bands for non-savings, non-dividend income in 2026/27, including a 42% higher rate from £43,663 and a 48% top rate above £125,140. Savings and dividend income follow UK-wide rates.
