Unless your earnings are very low, you are liable to pay Class 2 National Insurance Contributions if you are self-employed. Class 4 contributions may also be due on our profits.

If you employ staff, both you and your employees will pay Class 1 National Insurance, unless your earnings are very low. 

"Earnings" for NICs purposes include all cash remuneration. They are also payable on sick pay, holiday pay, etc. They are assessed on an individual's pay before pension contributions and before any charitable donations made under the payroll deduction scheme.

In addition to the "primary contributions" paid by the employee, employers are also required to pay "secondary contributions". There is no ceiling on the amount of an employee's earnings that will attract secondary contributions.
