Employee national insurance (NIC) is payable by your staff and it is your company’s responsibility as the employer to deduct your employee’s national insurance contribution from your staff salaries. Then, pay them over to HM Revenue and Customs.
For example, a staff under employment contract, you wold require to deduct Class 1 employee’s national insurance contribution from their pay. Whereas, for people working for your business as a freelancer or independent consultant, you pay them when they invoice your business. In that case you are not require to put these people in your payroll system. Thus no need to deduct any employee national insurance off their payments.
The UK national insurance contribution is administered by National Insurance Contributions Office (NICO).
