Income Tax & Personal Allowance: A Simple Guide

1. What is Income Tax?
Income tax is the money you pay to the government on the income you earn. This can include wages, salary, bonuses, some benefits, and income from self‑employment.

​

2. What is a Personal Allowance?
Your personal allowance is the amount of income you can earn each tax year before you start paying income tax. If your income stays below this amount, you usually don’t pay any income tax.

​

3. How Income Tax and Personal Allowance Work Together

  • First, your income for the year is added up.

  • Then, your personal allowance is taken off.

  • You only pay tax on what is left (this is called your taxable income).

 

Example:

  • Total income in the year: £20,000

  • Personal allowance: £12,570 (example figure)

  • Taxable income: £20,000 − £12,570 = £7,430
    You pay income tax only on the £7,430.

 

4. When Your Personal Allowance Can Change

Your personal allowance can be different if:

  • You earn a very high income (over a set limit, the allowance may go down).

  • You claim certain tax reliefs or allowances.

  • You are eligible for special allowances (for example, Blind Person’s Allowance or Marriage Allowance transfers).

 

5. Tax Bands (Basic Idea)

After your personal allowance, the rest of your income is split into bands. Each band is taxed at a different rate. For example:

  • A first band taxed at a lower rate (basic rate).

  • A middle band taxed at a higher rate (higher rate).

  • A top band taxed at the highest rate (additional rate).

 

The exact bands and rates can change over time and may be different in different parts of the UK.

​

6. Why Personal Allowance Matters

  • It reduces how much of your income is taxed.

  • It helps you understand why two people with the same salary might pay different tax (if their allowances or reliefs are different).

 

7. Keeping Up to Date

  1. Tax rules, rates, and the personal allowance amount can change. Always check the latest information from official sources (like the UK government website) or a qualified tax professional.
