The forms P11D, and where appropriate P9D, which report details of expenses and benefits provided to employees and directors for the year ended 5 April 2016, are due for submission to HMRC by 6 July 2016. The process of gathering the necessary information can take some time, so it is important that this process is not left to the last minute. Employees pay tax on benefits provided as shown on the P11D, either via a PAYE coding notice adjustment or through the self assessment system. In addition, the employer has to pay Class 1A National Insurance Contributions at 13.8% on the provision of most benefits. The calculation of this liability is detailed on the P11D(b) form. The deadline for payment of the Class 1A NIC is 19th July (22nd for cleared electronic payment). HMRC produce an expenses and benefits toolkit. The toolkit consists of a checklist which may be used by advisers or employers to check they are completing the forms correctly. If you would like any help with the completion of the forms or the calculation of the associated Class 1A NIC please get in touch. Internet links: Toolkit
