If you’ve ever wondered about the 40% tax bracket and how it affects your income, you’re in the right place. In this guide, Ultra Tax Ltd breaks down everything you need to know about the higher rate of income tax in the UK, including who it applies to and how to reduce your tax liability effectively.

Understanding the UK Tax System
Before diving into the 40% tax bracket, let’s take a quick look at how the UK income tax system works. Income tax is calculated based on your annual earnings, and the tax you pay is divided into different bands or brackets, each with a corresponding rate.
For the 2024/25 tax year, the bands are as follows:
Band | Taxable Income | Tax Rate |
Personal Allowance | Up to £12,570 | 0% |
Basic Rate | £12,571 to £50,270 | 20% |
Higher Rate (40%) | £50,271 to £125,140 | 40% |
Additional Rate (45%) | Over £125,140 | 45% |
The Personal Allowance is the amount you can earn tax-free. Any income above that falls into one of the other tax brackets, based on your total earnings.
Who Does the 40% Tax Bracket Apply To?
The 40% tax bracket, also referred to as the higher rate of tax, applies to individuals earning above £50,270 per year. However, it’s important to note that this rate only applies to the portion of your income that exceeds the higher rate threshold.
For example:
If you earn £60,000 annually, only the amount over £50,270 (i.e., £9,730) is taxed at 40%.
The income below £50,270 is taxed at 20% (basic rate).
This approach, known as marginal taxation, ensures you are taxed progressively as your income increases.
How to Reduce Your Tax Bill in the 40% Tax Bracket
If you’re approaching or already within the higher rate tax bracket, there are several strategies to help reduce your tax liability:
1. Tax-Efficient Savings and Investments
Consider opening an Individual Savings Account (ISA) or Lifetime ISA. These accounts allow you to grow your savings tax-free, as no income tax is applied to the interest or dividends earned.
2. Pension Contributions
Making contributions to your pension is one of the most effective ways to reduce taxable income. Pension contributions are exempt from income tax, and many employers offer matching contribution schemes, further enhancing your savings.
3. Salary Sacrifice Schemes
Explore whether your employer offers a salary sacrifice scheme. This allows you to exchange part of your salary for non-taxable benefits, such as childcare vouchers or additional pension contributions.
4. Make Use of Allowances and Deductions
Take advantage of allowances like the Marriage Allowance (if applicable) or deductible expenses if you’re self-employed. These can help lower your taxable income.
5. Claim Tax Relief on Charitable Donations
As a higher-rate taxpayer, you can claim the difference between the basic rate and higher rate of tax on any Gift Aid donations. Declare this on your tax return or request an adjustment to your tax code via HMRC.
Understanding Your Tax Code
Your tax code is a key factor in determining how much tax is deducted from your earnings. HMRC assigns a tax code to everyone on the PAYE system, which reflects your allowances and deductions.
For example:
1263L: Indicates a higher personal allowance due to allowable expenses or deductions.
500L: Typically used for emergency tax situations.
It’s crucial to ensure your tax code is accurate to avoid overpaying or underpaying tax. You can check your tax code on your payslip, P45, or P60 and update it through HMRC if necessary.
Is the 40% Tax Bracket Subject to Change?
Yes, income tax rates and thresholds are set by the UK government and can change each year during the Budget announcement. For example, the higher rate of 40% has been in place since 1989. However, the current thresholds are frozen until 2028, which means more individuals may find themselves moving into the higher tax bracket over time.
