Income Tax is a tax on income. Not all income is taxable and you're only taxed on 'taxable income' above a certain level. However there are reliefs and allowances that can reduce the amount of tax you pay and in some cases mean you've no tax to pay.

Income Tax

Income Tax is the principal form of direct personal taxation in the UK. It takes the form of a proportion of a person's earnings, which is collected by HM Revenue & Customs and passed to the Treasury. It is charged on various sources of income like salaries, pensions, income from self employment and investment income.

Income is classed as Taxable or Non Taxable. Taxable income is the portion of income that is the subject to income tax.

Detailed information on how income tax is calculated, income tax allowances and rates,is available from GOV.UK.

Paying Income Tax

If you are employed the tax will be deducted by your employee under the PAYE scheme. If you have received interest, the tax is usually deducted by the payer.

Not all income is taxable, and there are allowances and reliefs you may be able to claim that can reduce your bill.

The amount of tax free income you can have in a year is called your personal allowance. It depends on your age; and can be affected by the level of your income. For couples one of whom is born before 6 April 1935 there is a Married Couple’s Allowance.

It is possible for some couples to transfer 10% of the personal allowance between them. This is being called the ‘Marriage Allowance’. It is completely different from the Married Couple’s Allowance. HMRC's online Marriage Allowance calculator tells couples instantly how much they could reduce their annual income tax bill by.

Blind people can get an additional allowance called the Blind Person’s Allowance.
