Navigating the complexities of taxes can be challenging, especially when you’re faced with high tax brackets like the 40 percent tax rate. Whether you’re a small business owner, a professional service holder, or an entrepreneur, understanding when and why you may be subject to the 40 percent tax rate is essential. If you’ve ever wondered about your tax obligations and how to plan your finances effectively, this blog post is for you. We’ll explain the 40 percent tax rate in the UK and provide expert advice to help you manage your tax burden with ease. By the end, you’ll not only understand when you pay this tax but also how to reduce it strategically.

What is the 40 Percent Tax Rate?

In the UK, the tax system is quite progressive. This implies that your tax payment proportion increases with your income. In addition, you pay 40% tax if your income exceeds a specific threshold. For the current tax year (2024/2025), the 40 percent rate kicks in once your income surpasses £50,270, which includes both income from employment and self-employment.

This implies that your tax payment proportion increases with your income. In addition, you pay 40% tax if your income exceeds a specific threshold.

Key Point:

  • The 40 percent tax rate on total income is known as the “top rate” of income tax.
  • It’s levied on earnings above £50,270 up to £150,000.
  • Earnings over £150,000 are taxed at 45 percent.

How Does the 40 Percent Tax Work?

Understanding how the 40 percent tax rate applies is crucial for effective financial planning, especially if your income is pushing past the basic tax threshold.  The UK tax system is divided into different steps and bands, meaning that your income is taxed at different rates and levels. It is not all at the same rate or all at an average rate.

2024/25 Income Tax Bands in England (excluding Scotland):

  • Personal Allowance: £0 – £12,570 – 0% tax
  • Basic Rate: £12,571 – £50,270 – 20% tax
  • Higher Rate: £50,271 – £150,000 – 40% tax
  • Additional Rate: Over £150,000 – 45% tax

Now, let’s break it down with a real-life example.

Example: Annual Income = £60,000

Let’s calculate how much tax you’ll pay if you earn £60,000 in a year.

Step-by-step Calculation:

  1. First £12,570 – This is your personal allowance, meaning it’s completely tax-free.You pay: £0
  2. Next £37,700 (£12,571 to £50,270) – This falls under the basic rate band.You pay: 20% of £37,700 = £7,540
  3. Remaining £9,730 (£50,271 to £60,000) – This is taxed at the higher rate. You pay: 40% of £9,730 = £3,892

Total Income Tax Payable:

  • Basic Rate Tax: £7,540
  • Higher Rate Tax: £3,892
  • Total Tax Payable: £11,432

So, although your income is £60,000, you are not taxed 40% on the whole amount—only on the portion over £50,270. This is a very common mistake or misunderstanding and often causes a lot of unnecessary panic during tax season.

Key Takeaway:

Income above the higher rate limit, i.e. income sources where you are considered to be in the higher tax bracket, will only be taxed at the highest rate of 40%. The rest will be taxed at other rates and at lower rates. This is what makes the UK tax system progressive and fairer for varying income levels.

Tip: With effective tax planning—like pension contributions or allowable expenses—you can potentially bring your taxable income below the 40% threshold.

In 2009, the higher rate of tax in the UK was 40 percent for earnings above £37,400. Over the years, the threshold has risen, but so has the complexity of the tax system, making it essential for individuals to seek professional advice on managing their tax obligations.

When Do You Pay 40 Percent Tax?

You only pay the 40 percent tax rate if your taxable income exceeds the threshold. Here’s how to determine when you will fall into the higher tax bracket:

  • Income from Employment: If your salary or wages are above £50,270, you will pay the 40 percent tax rate on the amount exceeding that figure.
  • Self-Employed Earnings: As a small business owner or freelancer, the same principle applies. Your taxable profit over £50,270 is taxed at the higher rate.
  • Other Income: This includes rental income, dividends, or interest from savings that may push you over the threshold.

Knowing when you start paying 40 percent tax can help you prepare, plan, and reduce surprises during tax season. In the UK, the 40% higher tax rate kicks in when your taxable income exceeds £50,270 for the 2024/25 tax year.

But it’s important to note: you don’t pay 40% on your entire income—only on the portion that exceeds £50,270.

Here’s a breakdown of different income sources and when they might push you into the higher tax bracket:

1. Income from Employment (PAYE)

If you’re a full-time employee or earn wages through the Pay As You Earn (PAYE) system, the 40% tax rate applies only if your gross annual income exceeds £50,270.

Example:

  • Your salary is £60,000
  • First £12,570: Tax-free (Personal Allowance)
  • £12,571 to £50,270: Taxed at 20%
  • £9,730 (the part over £50,270): Taxed at 40%

You don’t pay 40% on the whole £60,000—only on the top slice.

2. Self-Employed Earnings & Business Profits

 

Whether you’re a freelancer, contractor, or small business owner, you’ll pay 40% tax once your taxable profits go above £50,270—after deducting allowable expenses.

Example:

  • Your total business income: £75,000
  • Allowable expenses: £10,000
  • Taxable profit: £65,000
  • 40% tax applies to the portion above £50,270 → £14,730 taxed at 40% = £5,892

Smart expense tracking and tax planning can help reduce this burden.

3. Other Income (Rent, Dividends, Interest)

Even if your main job pays below the threshold, additional income might push you into the 40% bracket. This includes:

  • Rental income from property
  • Dividends from shares
  • Interest from savings and investments

Example:

  • Your job pays £45,000
  • You earn £8,000 rental income
  • Total income: £53,000
  • 40% tax applies to £2,730 of your income

 You could pay higher-rate tax on your property income—even if your salary is below the threshold.

 

Key Things to Remember

  • Personal Allowance: Everyone can earn up to £12,570 tax-free.
  • You only pay 40% on income above £50,270, not the full amount.
  • If your total income from all sources is £50,270 or more, you are naturally in a higher rate step and band.
  • Dividends and savings income have separate tax-free allowances but still count toward your total income.
  • Income is cumulative, so even part-time work, side hustles, or bonuses can tip you into the higher rate band.

How to Calculate Your Taxable Income:

It’s important to know how to calculate your income to determine whether you’ll be subject to the 40 percent tax rate. Here’s a quick guide:

  1. Total Income: Add up all your income sources.
  2. Allowable Expenses: Subtract any deductible expenses (business expenses, pension contributions, etc.).
  3. Taxable Income: The remaining amount is what is taxed. If it’s above £50,270, the higher tax rate applies.

Strategies to Minimize Your 40 Percent Tax Exposure

  • Pension Contributions: Increasing your pension contributions is a great way to reduce your taxable income and plan for the future.
  • Tax-Efficient Investments: Explore tax-free investment vehicles like ISAs (Individual Savings Accounts) to shield income from tax.
  • Business Expenses: As a business owner, ensure that all allowable business expenses are deducted from your income, lowering your taxable profit.
  • Tax Reliefs: Don’t overlook available tax reliefs such as the Marriage Allowance or Blind Person’s Allowance that can reduce your taxable income.
