Tax and National Insurance. You have to pay: Income Tax if you earn more than £958 a month on average - this is your Personal Allowance. National Insurance if you earn more than £157 a week.
National Insurance has to be paid by both employed and self-employed workers.
Your National Insurance contributions depend on your employment status and how much you earn. Not everybody has to pay National Insurance, but contributions count towards your state pension and other benefits.
If you have an employer, you'll pay Class 1 National Insurance contributions. This also includes if you're self-employed but work for an employer - it's your employer's job to pay your National Insurance through your payslips, as well as their own employer contributions of 13.8%.
It's worth finding out if you're exempt from paying National Insurance. If you don't have to pay National Insurance you might be eligible for National Insurance credits, or you can choose to make voluntary contributions.
