Understanding the UK Personal Allowance (2025 Update)

What is the Personal Allowance?

The Personal Allowance is the amount of income that you can earn each tax year without paying Income Tax. For the 2025/26 tax year, the standard UK Personal Allowance is £12,570.

Who is Eligible?

Everyone who is a UK taxpayer is entitled to the Personal Allowance, including:

• Employees
• Freelancers
• Self-employed individuals
• Students

🚀 Quick Fact: If your total income is below £12,570, you typically don’t pay any income tax at all. This is your tax-free threshold, helping answer the question: how much can I earn before tax?

However, if you earn over £100,000, your allowance gets reduced. Let’s explore how.

UK Income Tax Bands Explained

Once your earnings go over the Personal Allowance, you start paying Income Tax according to different income tax bands. Here are the current UK income tax rates:

Income Range	Income Tax Band	Rate
Up to £12,570	Personal Allowance	0%
£12,571 to £50,270	Basic Rate	20%
£50,271 to £125,140	Higher Rate	40%
Over £125,140	Additional Rate	45%

You only pay the tax rate on the portion of income within that band. If you’re asking how much can I earn before tax applies in a meaningful way, this table gives you clarity.

How Income Tax is Calculated (With Example)

Real-World Calculation

Let’s break it down with a clear example.

Earnings: £52,000/year

• First £12,570 = 0% (Personal Allowance)
• Next £37,700 = 20% Basic Rate = £7,540
• Remaining £1,730 = 40% Higher Rate = £692

Total Income Tax = £7,540 + £692 = £8,232/year

By understanding how much can I earn before tax applies to different brackets, you can forecast and plan your finances better.

Student Tax Rules in the UK

Do Students Pay Tax?

If you’re a student and working part-time, you still get the Personal Allowance of £12,570. So, unless you exceed that threshold in total earnings for the year, you won’t pay any tax.

If your employer deducts tax anyway (under PAYE), you can usually claim it back from HMRC at the end of the tax year.

This reinforces the answer to how much can I earn before tax: students benefit significantly from staying under that threshold.
