    What is income tax?

    Income tax is a tax you pay on your income and for most people it is paid through your employer’s PAYE system. Each employee will have a tax code that will tell your employer how much to deduct from your gross pay.

    If you are self-employed, you can pay income tax through a tax return every year.

    What is national insurance?

    You will pay compulsory national insurance if you are over 16 and either:

    • employed and earning over £ 184 per week
    • self-employed and making a profit of £ 6,515 or more per year.

    Payment of national insurance contributions allows you to claim special benefits and state pension.
