Employer National Insurance Contributions (NICs)

As an employer, you have to contribute a lot more payment than just the salary of your employees. You also have to pay for National Insurance Contributions for each of your employees. So you may be asking, what is National Insurance and what exactly are you obligated to take care of. This article will give you all of the information you need and answer any questions regarding the matter that you may have.

What is National Insurance (NI)?

National Insurance is the fraction of money that the government takes from your earnings to help support state pensions as well as other benefits including Jobseekers Allowance, both Employment and Support Allowance, Maternity Allowance (although not Paternity), and Bereavement Benefits. National Insurance Contributions are more commonly referred to as NIs or NICs and are paid by those who are self employed and employed.

Although it is referred to as a contribution, it is a mandatory payment. As long as you are above the age of 16, below the retirement age, and either employed or self employed, you will have to pay National Insurance Contributions. Once a British citizen has reached the age of 16 they will be given a National Insurance number. Your National Insurance number is needed for you to obtain a job.
