How to pay Class 1 National Insurance contributions
As an employee (if you're a limited company director, this includes you) your Class 1 National Insurance contributions will be deducted from your salary payments by your employer (the company) every time payroll is run. Find out more about how employers run and report payroll to HMRC using FreeAgent.
National Insurance payments for self-employed people
Class 1 National Insurance contributions are only for employees who receive a salary. If you are self employed you will not pay Class 1 National Insurance contributions; you will pay Class 2 and Class 4 National Insurance instead.
