Dealing with the UK’s tax system can feel challenging, with various rates and rules to consider. However, you can better manage your finances with clarity on the income tax brackets and rules for the 2024-25 tax year. The tax system in the UK is progressive, meaning the higher your income, the higher the rate of tax you’ll pay on the top portion of your earnings.
This guide explains how income tax works in the UK, including each tax band, and provides practical examples to help you understand what these numbers mean for your take-home pay.
What Are Tax Brackets?
Tax brackets are thresholds used to apply different tax rates to different portions of income. The more you earn, the higher the tax rate applied to your income above certain levels. In the UK, income tax is calculated according to these brackets, and each rate applies only to the portion of income within that band, making the system progressive. Let’s break down the brackets for 2024-25.
2024-25 UK Tax Brackets
Personal Allowance: £0 – £12,570 (0% Tax)
The Personal Allowance is the amount of income you can earn before you start paying income tax. For most taxpayers, this is set at £12,570. You won’t owe any income tax if you earn £12,570 or less during the tax year.
However, if your income exceeds £100,000, the Personal Allowance begins to taper off. For every £2 you earn over £100,000, you lose £1 of your allowance. Once your income reaches £125,140, you’ll lose your Personal Allowance entirely.
Example:
If your income is £110,000, the personal allowance reduces by £5,000 (£10,000 / 2), leaving you with a personal allowance of £7,570 rather than £12,570.
If you earn £125,140 or more, you won’t have any Personal Allowance, and all your income will be taxable.
Maximising Your Personal Allowance
Consider these strategies:
Marriage Allowance Transfer: If you’re married or in a civil partnership, you may be able to transfer up to 10% of your unused personal allowance to your partner, reducing their tax bill. Conditions apply:
The lower-earning partner’s income must be below £12,570.
The higher-earning partner must be a basic-rate taxpayer with income between £12,571 and £50,270.
Pension Contributions: Adding to your pension is a way to reduce taxable income and possibly preserve your personal allowance. Contributions are deducted from your gross income (except for workplace pensions under a net pay arrangement).
Basic Rate: £12,571 – £50,270 (20% Tax)
Once you earn above the Personal Allowance threshold, your income up to £50,270 is taxed at the Basic Rate of 20%.
Example:
If you earn £30,000:
The first £12,570 is tax-free.
The remaining £17,430 (£30,000 – £12,570) is taxed at 20%, totaling £3,486 in tax.
Higher Rate: £50,271 – £125,140 (40% Tax)
For income falling between £50,271 and £125,140, the tax rate rises to 40%. This rate only applies to the income within this range.
Example:
For someone earning £80,000:
£0 – £12,570: Tax-free.
£12,571 – £50,270: 20% rate on £37,700 = £7,540.
£50,271 – £80,000: 40% rate on £29,730 = £11,892.
Total tax bill: £19,432.
Additional Rate: Over £125,140 (45% Tax)
This is the highest tax rate in the UK, applied to income above £125,140.
Example:
For someone earning £150,000:
£0 – £50,270: 20% rate on £50,270 = £10,054.
£50,271 – £125,140: 40% rate on £74,869 = £29,948.
Above £125,140: 45% rate on £24,860 = £11,187.
Total tax owed: £51,189.
Changes and Implications for the 2024-25 Tax Year
For 2024-25, tax brackets remain unchanged from the previous year. However, with inflation, more people may fall into higher tax bands—a phenomenon known as “fiscal drag.” This means:
Frozen Thresholds and Fiscal Drag: Tax thresholds remain fixed while inflation increases salaries, which can push taxpayers into higher bands, raising their effective tax rate even if their real income (adjusted for inflation) hasn’t increased.
