NIM10020 - Aggregation of Earnings: Calculation & recording: NICs due at contracted-out & not contracted-out rate: No Appropriate Personal Pension (APP): Contracted-out earnings reach or exceed UEL: Tax years 1998/1999 & earlier

All examples on this page use the 1998-99 rates and earnings bands. NICs are worked out using the exact percentage method and are based on the employee being a member of a Contracted-Out Salary Related (COSR) scheme.

When calculating NICs, priority is given to the contracted-out earnings. NICs are worked out on the total earnings using the shortest earnings period of the contracted-out employment(s).

Employee’s NICs are worked out at the:

  • initial percentage rate on earnings up to and including the LEL, and
  • main contracted-out percentage rate on earnings above the LEL up to and including the UEL

Employer’s NICs are worked out at the:

  • highest not contracted-out percentage rate on earnings up to and including the LEL
  • highest contracted-out percentage rate on earnings up to and including the UEL, and
  • highest not contracted-out rate on the balance of the total earnings.

EXAMPLE

S. Davies earns £2,220 per month from his contracted-out job and £200 per month from his not contracted-out job. The total earnings are £2,420 per month and the earnings period is monthly.
