Late payment of Class 1A NIC


Form P11D: Completion is required by an employer if it reimburses an employee with any expenses that are not covered by an exemption (or prior to 2016 a PAYE dispensation) and in respect of any taxable benefits made available to an employee by the employer or via a third party, during the course of the tax year.



Unpaid tax

HMRC will charge up to three penalties of 5% of the amount of Class 1A NICs that are due, depending on the length of time that the amount remains unpaid as follows:
