National Insurance (NI), tax and minimum wage

This page contains information on the UK minimum wage and the taxes that may be deducted from your earnings.

National Insurance (NI)

The UK Government will make deductions from your wages for National Insurance (NI) contributions, which are used for funding the state welfare system (e.g. NHS and benefits). If you earn above £155 a week your wages will be deducted for NI contributions. You cannot reclaim NI deductions.

If you don’t have a National Insurance number, you can apply for it only once  you are in the UK. You must have the right to work or study in the UK to get a National Insurance number. To do this you need to call the National Insurance number application line on 0345 600 0643. You will be asked a number of questions (e.g. your personal details, employers details) and will then be required to attend an appointment at a local Jobcentre Plus branch. You will be asked to bring documents to this appointment so that they can be checked.

This procedure can take a number of weeks, therefore during this time you can work using a temporary NI number. You should be able to get this from your employer. If not then contact the Guild of Students or the Advice and Representation Centre (ARC) for further information.

For further information on National Insurance please phone the National Insurance Enquiry Line: 0300 200 3500.

Tax

Everyone in the UK, including students, has to pay tax on their earnings. The government department that deals with this is called the Inland Revenue. The amount of tax that you have to pay depends on how much you earn. The tax is paid by your employer and is deducted from your wages each time you are paid (known as 'PAYE'- pay as you earn). This will be displayed on your payslip.

All adults are entitled to a 'Personal Allowance' which is an amount of income that you can earn without being taxed on it each year. The figure for the tax year 6 April 2016 to 5 April 2017 is £11,000 per year.

The amount you earn over the personal allowance between 6 April 2016 and 5 April 2017 will be taxed.

If your employer has taxed you (e.g. if you earn above the personal allowance each week or month) but you do not earn above your personal allowance during the tax year (£11,000), you can reclaim the tax that you have paid from the Inland Revenue.

If you only intend to work during vacations and do not expect to earn more than the personal allowance (£11,000) in the tax year, you should ask your employer for a P38(S) form. By completing the form your employer will not deduct tax from your wages.

For further information on income tax please visit the HMRC income tax pages or telephone Income Tax enquiries on 0300 200 3300.

How much is the minimum wage?
