Casual, part-time, temporary workers - tax and National Insurance

If you work part-time or on a casual or temporary basis you usually pay Income Tax and National Insurance contributions if you earn more than a certain amount each year. This applies whether you are employed or self-employed.

If you work for an employer

If you're employed on a casual, temporary or part-time basis by law your employer must:

  • deduct tax and National Insurance contributions from your wages
  • give you payslips
  • deduct student loan repayments, if relevant
  • give you a form P45 when you leave
  • give you a P60 tax summary at the end of each tax year if you still work for the employer

What about cash in hand?

It's illegal for your employer to pay you cash in hand without deducting tax and National Insurance contributions from your wages.

If you accept money in this way, you risk losing your employment rights and the right to some benefits, such as:

  • maternity or paternity leave
  • sick pay
  • Jobseeker's Allowance

In addition you could end up having to pay the tax and National Insurance contributions yourself.

If you suspect your employer of not paying tax or National Insurance contributions on your wages you can report them in confidence using the Tax Evasion Hotline on Tel 0800 788 887. Lines are open Monday to Friday 8.00 am to 6.00 pm and are normally less busy before 9.00 am.

If you work for more than one employer

If you work for more than one employer, you'll get a special tax code to take this into account.

Your tax allowances - amounts that you can get to reduce your tax bill - will normally be given against the pay from your main job. Your other job(s) will be taxed at the basic, higher or additional rate, depending on your total income.

Employment rights

All employees have rights, whether they are full or part-time, casual or temporary, including:

  • holiday pay
  • national minimum wage
  • protection from discrimination

If you're concerned about your rights, you can ask a union for help or get free advice from your local Citizens Advice Bureau.

If you're a pensioner

If you're a pensioner, that is, you are State Pension age or older, you don't need to pay National Insurance contributions on any earnings you receive but you may still need to pay Income Tax - follow the links below to find out more.

If you're a student

If you're a student, you still pay tax on your income unless all of the following apply:

  • you're a full time student in the UK, only working in the holidays
  • you're returning to full time education after the holiday
  • your total income for the year is below the Personal Allowance

Ask your employer for form P38S Student Employees - and tax won't be deducted from your earnings. National Insurance will still be deducted if you earn more than £146 a week.

Please note: From 6 April 2023 employers will no longer use the P38(S) process. Your employer will operate PAYE (Pay As You Earn) to deduct Income Tax and National Insurance from your wages. If you are employed by an employer who is part of the Real Time Information (RTI) pilot, the normal PAYE process will apply from 6 April 2012.

If you work for yourself

If you're self-employed on a temporary or part-time basis you must register for business taxes with HM Revenue & Customs (HMRC) as soon as you start work. You'll have to complete a Self Assessment tax return and are responsible for paying your own tax and National Insurance contributions on the income you earn.

Even if you don't think you'll earn enough to need to pay tax, you still need to complete a tax return.

Working for cash

You can accept cash payments for work you do, but it's illegal for you not to declare this on a Self Assessment tax return, and pay Income Tax and National Insurance contributions if these are due. This will depend on your overall taxable income in the tax year.

Checking your employment status

It's important to understand the difference between being employed and self-employed, as this affects how you pay tax and National Insurance contributions.

If you’re a pensioner

You stop paying Class 2 National Insurance contributions as soon as you reach State Pension age. You stop paying Class 4 contributions from the start of the tax year after the one in which you reach State Pension age. But you may still need to pay Income Tax.

Does how much you earn affect the tax you pay?

Everyone gets a personal tax-free allowance (basic Personal Allowance is £8,105 in 2012-13). You don't pay tax on anything you earn below this amount.

The National Insurance you pay also depends on your earnings or profits and whether you’ve reached State Pension age.

If you’re an employee, you do not pay any if you earn less than £146 a week (for the 2012-13 tax year).

If you’re self-employed, you may not have to pay Class 2 National Insurance contributions if you qualify for a Small Earnings Exception where your profits for the year are expected to be less than £5,595 for 2012-13.

Class 4 National Insurance contributions will only be due if your profits exceed £7,605 in 2012-13. If you're a pensioner, you don't have to pay National Insurance contributions.
