If you’ve ever received a pay rise, secured a big contract, or grown your business, you may have heard the term “40% tax bracket.” This term refers to the higher income tax rate in the UK, and it’s important for higher‑earning individuals, small business owners, and professionals who want to understand how their income is taxed and plan effectively. This article explains how the 40% tax bracket works, the current thresholds for the 2026/27 tax year, how to calculate your tax, strategies to reduce your tax bill, and how these rules may impact you now and in the near future.
Introduction to the 40% Tax Bracket
The 40% tax bracket in the UK applies to income between £50,271 and £125,140 for the 2026/27 tax year. It is often referred to as the higher rate of tax, any income you earn within this range is taxed at 40%, while income outside this range is taxed at different rates.
How the 40% Tax Bracket Fits into the UK Tax Landscape
The UK income tax system is divided into different levels. It starts with the personal allowance, where you don’t pay any tax on income up to £12,570. After that, income between £12,571 and £50,270 is taxed at 20%, known as the basic rate. Then, any income between £50,271 and £125,140 falls into the 40% tax bracket. Beyond that, income over £125,140 is taxed at 45%. Only the portion of your income that falls within the 40% tax bracket is subject to that higher rate, not your entire income.
How Much Can You Earn Before Paying 40% Tax in 2026/27?
You can earn up to £50,270 before any of your income is taxed at 40%.
- First £12,570 = 0% (Personal Allowance)
- £12,571 – £50,270 = 20% (Basic rate)
- £50,271 and above = 40% (Higher rate)
Calculating Your Taxable Income
If you’re wondering how much tax you’ll pay, tools like an income tax calculator UK can help. For instance, with an income of £60,000, your tax calculation would be as follows:
- 0% tax on the first £12,570
- 20% tax on income ranging from £12,571 to £50,270
- 40% tax on income between £50,271 and £60,000
So, only the amount between £50,271 and £60,000 (i.e., £9,729) will be taxed at the 40% rate. Using a salary after tax tool can give you a clearer idea of your take-home pay.
Financial Impact of the 40% Tax Rate
Being in the 40% tax bracket can significantly affect your take-home pay. It’s important to plan accordingly to avoid financial strain. Understanding how much tax you’ll owe allows you to budget effectively and explore ways to optimise your tax efficiency.
How to Avoid 40 Tax in the UK (Legally)
If you wish to reduce your tax liability within the 40% bracket, here are 7 proven, legal strategies:
- Contribute to a Pension: Pension contributions are deducted from your income before tax is calculated, saving you 40% on every pound contributed (up to annual limits).
- Maximise ISAs: Individual Savings Accounts let you save or invest up to £20,000 per year completely tax-free on interest and capital gains.
- Claim All Eligible Business Expenses: (especially useful if self-employed) Deduct office supplies, travel, home office costs, and more to lower your taxable profit.
- Use Gift Aid and Charitable Donations: Donations made under Gift Aid can reduce your tax bill when you’re a higher-rate taxpayer.
- Salary Sacrifice: Sacrifice part of your salary into a pension or benefits package — this can keep you below the £50,271 threshold or reduce the amount taxed at 40%.
- Marriage Allowance: If your partner earns less than the Personal Allowance, you may be able to transfer £1,260 of allowance and save up to £252 in tax per year.
- Consider a Limited Company (for self-employed): Operating through a limited company can offer more tax planning opportunities than being a sole trader.
Tax Bracket for Self Employed – What’s Different?
Self-employed individuals (sole traders or limited company directors) use the same income tax bands as employees:
- 0% up to £12,570
- 20% basic rate
- 40% higher rate from £50,271
The main difference is National Insurance (Class 2 & Class 4 for sole traders) and the ability to claim more business expenses. Many self-employed people switch to a limited company structure to optimise tax when they approach the 40% bracket.
Will the 40% Tax Bracket Change in the Future?
Yes, the 40% tax bracket can change, as tax rates are reviewed every year in the government’s annual Budget. Changes are made based on the country’s economy and government decisions. While the 40% rate has stayed the same for a few years, it’s important to keep an eye out for any updates. For now, the UK’s tax bands are frozen until 2028, but this could be adjusted later.
Understanding the 40% tax bracket and how it works is crucial for effective financial planning. While it may seem intimidating, remember that it only applies to the portion of your income above the threshold. With the right strategies, like tax-efficient investments or pension contributions, you can manage your tax bill more effectively.

What Does Your 40 Tax Code Mean?
If HMRC knows you are a higher-rate taxpayer, you may see the tax code D0 on your payslip. This tells your employer to deduct tax at 40% on all your earnings above the Personal Allowance. The most common code for basic-rate taxpayers is 1257L. Always check your tax code; an incorrect code can mean you’re paying too much or too little tax.
