How Does the 40% Tax Bracket Work? – [2026 Guide]

Seeing a 40% Income Tax rate can sound concerning, but being in the 40% tax bracket does not mean you pay 40% tax on your entire income. The UK uses a progressive tax system, so different portions of your taxable income are taxed at different rates.

The 40% tax bracket applies only to the portion of your taxable income that falls within the higher-rate band, not your entire salary.
For the 2026/27 tax year, the standard Personal Allowance is £12,570. In England, Wales and Northern Ireland, income within the higher-rate band is taxed at 40%, while Scotland has its own Income Tax bands and rates.

Understanding how the 40% tax bracket works can help you estimate your tax liability and make informed financial decisions.

What Is the 40% Tax Bracket?

The 40% tax bracket is the higher Income Tax rate for taxable income between £50,271 and £125,140 in the 2026/27 tax year for people in England, Wales and Northern Ireland.

For 2026/27 in England, Wales and Northern Ireland:

  • Personal Allowance: up to £12,570 at 0%, where eligible
  • Basic rate: 20%
  • Higher rate: 40%
  • Additional rate: 45% above the relevant threshold

With the standard Personal Allowance, the higher-rate threshold is £50,270 of total income, and the 40% rate generally applies to taxable income between £50,271 and £125,140.

Importantly, you do not pay 40% on your whole salary simply because you enter the higher-rate band.

Example

Suppose you earn £60,000 and receive the full £12,570 Personal Allowance.

Your taxable income is broadly:

£60,000 − £12,570 = £47,430

The first £37,700 of that taxable income falls within the basic-rate band and is taxed at 20%. The remaining £9,730 falls into the higher-rate band and is taxed at 40%.

This illustrates why understanding tax bands is more useful than simply looking at your headline salary.

Taxable Income and How to Calculate It?

Taxable income is not necessarily the same as your gross income.

Depending on your circumstances, your income may include:

  • Employment income
  • Self-employment profits
  • Pension income
  • Rental income
  • Savings interest
  • Dividend income
  • Certain other taxable sources

You then consider applicable allowances, reliefs and deductions to determine how much is actually subject to Income Tax.

A simplified calculation is:

Gross income − applicable allowances and reliefs = taxable income

However, tax calculations can become more complicated when you have multiple income sources, pension contributions, benefits in kind or income above £100,000.

Who Does the 40% Tax Bracket Apply To?

The 40% higher-rate band can apply to individuals whose taxable income moves into the higher-rate range.

This may include:

  • Employees receiving a significant salary increase
  • Business owners taking taxable income from their businesses
  • Self-employed individuals with higher profits
  • Landlords receiving taxable rental profits
  • Individuals with multiple income sources
  • People receiving bonuses, commissions or other additional earnings

It is worth remembering that Income Tax treatment differs in Scotland. For 2026/27, Scotland has a 42% higher rate applying to a different income range, alongside starter, basic, intermediate, advanced and top rates.

How the 40% Tax Bracket Works

  • Starting point: You pay 40% tax only on the part of your taxable income above £50,270.
  • End point: If your taxable income goes above £125,140, the amount above this threshold is taxed at the 45% additional rate.
  • How it works: You do not pay 40% tax on your whole salary. The first £12,570 is usually covered by your Personal Allowance, and the next £37,700 is generally taxed at 20%.
  • What counts as income: HMRC may include different types of taxable income when working out which tax band you fall into, such as salary, rental income, savings interest and dividends.

You can check the latest Income Tax rates and thresholds on GOV.UK Income Tax Rates and Allowances.

How Much Can I Earn Before I Pay 40% Tax?

For someone in England, Wales or Northern Ireland who receives the full £12,570 Personal Allowance, the higher rate generally begins once total income exceeds £50,270.

For example:

Annual income

General position

£40,000

Generally within the basic-rate band

£50,000

Generally below the higher-rate threshold

£60,000

Part of the taxable income is taxed at 40%

£100,000

Higher-rate tax applies to part of taxable income

£125,140+

Personal Allowance may have been fully withdrawn

These examples assume straightforward circumstances and the standard Personal Allowance. Other income, deductions and reliefs can change the calculation.

Personal Allowance and Tax Relief

The standard Personal Allowance for 2026/27 is £12,570. However, this allowance is gradually reduced when adjusted net income exceeds £100,000.

The allowance reduces by £1 for every £2 of income above £100,000. It can eventually reduce to zero when income reaches £125,140.

This creates an important planning point for higher earners.

Tax reliefs can also affect your overall tax position. For example, qualifying pension contributions may provide tax relief and can be relevant when managing income around higher-rate thresholds.

Because the rules can depend on the type of income and individual circumstances, professional advice can be particularly useful if your income is approaching or exceeding £100,000.

How Can I Stay Informed About Tax Changes?

There are several practical ways to keep up with UK tax developments:

  1. Check HMRC guidance – GOV.UK publishes current Income Tax rates and allowances.
  2. Review your tax code – Your PAYE tax code can affect how much tax your employer deducts.
  3. Review your income regularly – Bonuses, salary increases and additional income can move you into another tax band.
  4. Monitor pension contributions and tax reliefs – These may affect your taxable position.
  5. Speak to an accountant – Professional advice can be particularly valuable when your income is close to a tax threshold.

HMRC’s published rates confirm the current tax bands and allowances for each tax year.
