Who should use our Income Tax calculator?
Almost all incomes are taxable. The most common taxable income is the salary and wages you earn. However, you may also need to pay Income Tax on the following incomes:
- Rent from your tenants
- Interest and Dividends from investments and savings
- Business profits
Income tax is charged into different bands. As your income increases, so does your income tax.
Your taxable income is reduced by any allowances you qualify for, like personal allowance.
What is Personal Allowance in the context of income tax?
An allowance is an amount of income you earn without paying any income tax. Personal allowance is the most common type of allowance to which every individual, including students, is entitled. The exact amount for personal allowance varies with each year. For the current financial year 2023-24, the Personal Allowance is £12,570.
In addition to Personal Allowance, there is Marriage Allowance, Child Allowance, and Blind Person's Allowance available to you based on your circumstances.
How is income tax calculated in the UK?
UK chancellor usually sets the income tax rates during the Spring and Autumn Budget. This year, the Income Tax rates are:
| Income | Income tax band | Income tax band name |
|---|---|---|
| Up to £12,570 | 0% | Personal allowance |
| £12,571 to £50,270 | 20% | Basic rate |
| £50,271 to £125,140 | 40% | Higher rate |
| Above £125,141 | 45% | Additional rate |
You don't pay income tax at the same rate on all taxable income. For instance, if you earned £70,000 in 2023-24, your income tax will be calculated as:
First £12, 570 = No tax
£37,700 (£50,270 - £12, 571) = 20% Tax Rate
£19,730 (£70,000 - £50,270) = 40% Tax Rate
