NIC for Employees

The amount of NIC paid by workers is influenced by whether you are contracting out of SERPS or S2P known as the State Second Pension Scheme. If the employee has contracted out of SERPS and into a salary-related scheme.
Then at the basic level, the NIC rates were reduced by 1.4% for the employee and 3.4% for the employer.
