Class 1: Personal Liability Notices: Contents of a PLN

Section 121C, Social Security Administration Act 1992

Under the terms of the above legislation, a Personal Liability Notice will:

  • Specify the amount of National Insurance Contributions that have not been paid, plus any interest and penalties chargeable on these contributions
  • Require the individual to pay that amount, plus statutory interest at the prescribed rate and which runs from the date the notice is issued

Where there is one culpable officer, that individual will be required to pay the full amount of the company NIC debt.

Where there is more than one culpable officer, the Personal Liability Notice will specify the proportion of the total amount that is due from each individual officer, having taken into account the culpability of each individual officer.
