Introduction to The UK Income Tax

Income Tax – the basics

Income Tax is a tax on income. Not all income is taxable and you’re only taxed on ‘taxable income’ above a certain level. Even then, there are other reliefs and allowances that can reduce your Income Tax bill – and in some cases mean you’ve no tax to pay.

What counts as taxable income?

Taxable income includes:

  • earnings from employment
  • earnings from self-employment
  • most pensions income (State, company and personal pensions)
  • interest on most savings
  • income from shares (dividends)
  • rental income
  • income paid to you from a trust

Non-taxable income

There are certain sorts of income that you never pay tax on. These include certain benefits, income from tax exempt accounts, Working Tax Credit (WTC) and premium bond wins. These income sources are ignored altogether when working out how much Income Tax you may need to pay.

Tax-free allowances

Nearly everyone who is resident in the UK for tax purposes receives a ‘Personal Allowance’, which is an amount of taxable income you’re allowed to earn or receive each year tax-free.

This tax year (2009-10), the basic Personal Allowance – or tax-free amount – is £6,475. You may be entitled to a higher Personal Allowance if you’re 65 or over.

If you’re registered blind, or are unable to perform any work for which eyesight is essential, you can also claim the tax-free Blind Person’s Allowance.

Income Tax is only due on taxable income that’s above your tax-free allowances.

Allowances and reliefs that can reduce your Income Tax bill

If you’re due to pay Income Tax, there are a number of deductible allowances and reliefs that can reduce your tax bill. These include:

  • Married Couple’s Allowance – the husband, wife or civil partner has to be born before 6 April 1935
  • Maintenance Payment Relief – either you or your former spouse or civil partner must have been born before 6 April 1935

Unlike the tax-free allowances, these aren’t amounts of income you can receive tax-free. Rather they’re amounts that can reduce your tax bill.

Tax allowances and reliefs for employees or directors

If you’re an employee or director you might be able to get tax relief for business expenses you’ve paid for.

Tax on company benefits

If you’re employed and you receive non-cash benefits from your employer you will have to pay tax on them.

Taxable benefits

Benefits that you might have to pay tax on include:

  • company cars or vans
  • fuel provided for your vehicle
  • medical insurance
  • living accommodation
  • loans at low interest rates

How much Income Tax you pay

After your allowable expenses and any tax-free allowances have been taken into account, the amount of tax you pay is calculated using different tax rates and a series of tax bands.

Income Tax bandIncome Tax rate on non savings incomeIncome Tax rate on savingsIncome Tax rate on dividends
£0 to £2,440
Starting rate for savings:
Not available10%n/a – see basic rate band
£0 to £37,400
Basic rate:
20%20%10%
£37,401 and above
Higher rate:
40%40%32.5%

Because the rate of Income Tax you pay on savings is worked out after any non-savings income has been taken into account, if your non-savings income is less than the starting rate for savings limit (£2,440) – or if savings and investments are your only source of income – your savings income will be taxed at the 10 per cent starting rate up to the limit. But if you already have non-savings income which takes you above the starting rate, all of your savings will be taxed at the 20 per cent basic rate.

Remember, the tax band applies to your income after your tax allowances and any reliefs have been taken into account – you’re not taxed on all of your income.

‘Non savings income’ includes income from employment or self-employment, most pension income and rental income.

‘Dividends’ means income from shares in UK companies. Savings and dividend income is added to your other taxable income and taxed last. This means you pay tax on these sorts of income based on your highest Income Tax band.

How you pay Income Tax

Income Tax is collected in different ways depending on the type of income and whether you’re employed, self-employed or not working. The different ways Income Tax is collected include:

  • PAYE (Pay As You Earn)
  • Self Assessment
  • tax deducted ‘at source’ whereby tax is deducted from bank/building society interest before the interest is paid to you
  • in some cases, one-off payments

If you’re an employee or you receive a company or private pension, your employer or pension provider will deduct tax through PAYE. If you’re self-employed, you’ll be responsible for filling in a Self Assessment tax return and paying your own tax.

Paying the right amount of Income Tax

It’s important to check that you’re paying the right amount of tax. You can do this by checking your:

  • total taxable income
  • tax-free allowances and reliefs
  • current tax code (if relevant)

If you’re paying too much tax you can claim this money back. If you’re an employee or you receive a company or personal pension and you think you’re paying too little tax you’ll need to contact HMRC to change your tax code.

National Insurance

As well as paying Income Tax on your income, you’ll also have to pay National Insurance contributions. National Insurance contributions build up your entitlement to certain social security benefits, including the State Pension. The amount of National Insurance you pay depends on how much you earn and whether you’re employed or self-employed. You stop paying National Insurance contributions when you reach retirement age.

Should you be paying Income Tax?

Not all income is taxable – and you’re only taxed on income above a certain level. If your taxable income is more than your tax-free allowances you must contact HM Revenue & Customs (HMRC) if you’re not already paying tax. If it’s less than or equal to your allowances, you shouldn’t be paying tax and may be due a refund.

Working out whether you’re a taxpayer

To work out if you’re a taxpayer follow these three steps:

  • add up all your taxable income
  • work out your tax-free allowances
  • take your tax-free allowances away from your taxable income

Step one – add up your taxable income

Some income is taxable and some is never taxed. To see if you’re a taxpayer, you first add up your taxable income in a tax year (6 April to 5 April) – you can ignore your non-taxable income. To view or print off a list of taxable and non-taxable income, follow the link below.

Step two – add up your tax free allowances

Tax-free allowances are amounts of income you can get without paying tax. They include the Personal Allowance and the Blind Person’s Allowance.

Personal Allowance

Everybody gets the basic Personal Allowance, but if you’re 65 or over and your income is below certain levels the rate increases.

Personal Allowance rates2009-10Income limit (see note)
Basic£6,475none
Age 65 to 74£9,490£22,900
Age 75 or over£9,640£22,900

Note: If your income is over the income limit, HMRC will reduce the age-related allowance by half of the amount – £1 for every £2 – you have over that limit, until the basic rate allowance is reached.

You’ll always get the basic allowance, whatever the level of your income. So if, for example, you’re 66 and have an income of £23,500 (£600 over the limit) they would reduce your age-related allowance of £9,490 by £300 to £9,190.

Blind Person’s Allowance

If you’re certified blind and are on a local authority register of blind persons, or if you live in Scotland or Northern Ireland and you are unable to perform any work for which eyesight is essential, you can claim Blind Person’s Allowance. If you’re married or in a civil partnership and can’t use all your allowance, you can give the unused part to your spouse or civil partner.

Even if you have no taxable income, it might still be worth claiming Blind Person’s Allowance as your spouse or civil partner could benefit from your allowance. The Blind Person’s Allowance for the tax year 2009-10 is £1,890.

Step three – work out if you’re a taxpayer

Take your tax-free allowances away from your taxable income. If there’s anything left, you count as a taxpayer and must contact HMRC if you’re not already paying tax. If there’s nothing left you shouldn’t be paying any tax and may be due a refund.

Taxpayer: worked example

You are 76 and registered blind. You’ve added up your taxable income and it comes to £19,000.

  • your taxable income is £19,000
  • your tax-free allowances add up to £11,530 (age-related Personal Allowance of £9,640 plus Blind Person’s Allowance of £1,890)
  • you subtract your tax-free allowances (£11,530) from your taxable income (£19,000) – this leaves you with taxable income of £7,470

Non-taxpayer: worked example

You are 46 and have a part-time job. Your taxable income is £4,500.

  • your taxable income is £4,500
  • your tax-free allowance is £6,475 – the basic Personal Allowance
  • you subtract your Personal Allowance (£6,475) from your taxable income (£4,500) and find that you don’t need to pay tax on your income
  • if you have been paying tax, you may be due a refund

Allowances that can reduce your tax

Bear in mind that even if you count as a taxpayer, you may qualify for certain ‘tax deductible’ allowances that can reduce your tax bill, or in some cases mean you have nothing to pay.

Taxable income that you can receive tax-free

Everyone is entitled to receive a certain amount of taxable income tax-free during the tax year. This is called the Personal Allowance and it increases from age 65.

If you’re certified blind and on a local authority register of blind persons, or if you live in Scotland or Northern Ireland and you are unable to perform any work for which eyesight is essential, you can claim Blind Person’s Allowance. As with the Personal Allowance, this is an amount of taxable income you can receive during the tax year without paying tax.

Ways you pay Income Tax

If you’re an employee or receive a company pension

If you’re an employee your employer will deduct Income Tax from your wages throughout the year using the tax code HM Revenue & Customs (HMRC) provide to them, sending the deductions back to HMRC. If you get a pension, your pension provider will deduct tax in the same way. This system of collecting Income Tax is known as Pay As You Earn – usually shortened to PAYE.

If your circumstances change and you are given a new tax code, HMRC will send you a ‘PAYE Coding Notice’. This tells you what your tax code is and how they worked out the tax-free income you can receive. Keep all notice of coding letters in case you’ve got any questions or need to check you’re paying the right amount of tax.

At the end of the tax year HMRC may also send you a P810 Tax Review Form. This is a simple one page form that is used to check that your tax code is still correct. If you get form P810 you’ll need to fill it in and send it back as soon as you can.

If you prefer you can call the number on the form and give the information over the phone. You can tell them about other income you’ve received or about changes that may reduce your tax bill. If the information you give shows that you’re paying the wrong amount of tax, they can change your tax code straight away to correct this.

If you have complex tax affairs you may also have to complete a Self Assessment tax return.

If you’re self-employed

If you’re self-employed you’ll need to complete a Self Assessment tax return. You can complete and file your return online or fill in a paper form. You’ll probably need to pay any Income Tax you owe for a tax year in two instalments plus a final ‘balancing payment’.

Filling in your tax return online is easy and quick – and you can do it at any time of the day or night. Online tax returns are processed faster than paper returns, which means that if HMRC owe you any money you’ll get it more quickly. Your tax is also worked out automatically as you fill in the form so you’ll know what you owe – or are owed – right away.

If you’ve got complex tax affairs

If you’ve got complex tax affairs – for example if you earn money from rents or investments above a certain level – you may need to complete a tax return. You may have to do this even if you’re already on PAYE. But if you are on PAYE, HMRC may still be able to collect some or all of your Income Tax this way.

Income Tax deducted at source from savings income

Interest on most savings has 20 per cent tax deducted before you receive it. If you’re a basic rate taxpayer you’ll have no further tax to pay. If you’re a non-taxpayer you may be able to claim some tax back. If you’re a higher rate taxpayer you’ll have more tax to pay.

Some taxpayers may need to fill in a tax return or a form P810 Tax Review Form to make sure they’re paying the right amount of tax.

How to pay tax on extra income

You may be able to choose how you pay tax on any extra income you earn – either through PAYE throughout the following tax year or through Self Assessment by way of an additional payment.

If you’re an employee or a pensioner and you want to pay tax on some of your non-employment income – like investment and rental income – through PAYE rather than by Self Assessment you can ask HMRC to collect it this way. You can do this for up to £2,500 of extra income in a year. If you earn more than £2,500 from savings, investments or rental income you’ll need to fill in a tax return.

If you don’t want to pay tax on your non-employment income through PAYE, you can ask HMRC to stop collecting it this way. You’ll pay through Self Assessment instead. If you want to do this you can register for Self Assessment Online (if you’re not already registered). Or you can download a paper tax return to complete. Send this to HMRC with a letter to say you want to pay tax through Self Assessment.
