NIM10021 – Aggregation of Earnings: Calculation & recording: NICs due at contracted-out & not contracted-out rate: No Appropriate Personal Pension (APP): Contracted-out earnings do not reach LEL but total earnings do: 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
  • main not contracted-out percentage rate on any earnings above the LEL up to and including the UEL.

Employer’s contributions are worked out at the appropriate not contracted-out rate on the total earnings (including the contracted-out earnings)

EXAMPLE

C. Brown earns £45 per week from his contracted-out job, and £110 per week from his not contracted-out job. Total earnings are £155 per week and the earnings period is weekly.

Employee’s NICs due : £10.38 (Table letter A)

Employer’s NICs due : £10.85 (Table letter A)
