The forms P11D, and where appropriate P9D, which report employees' and directors' benefits and expenses for the year ended 5 April 2010, are due for submission to HMRC by 6 July 2010. 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 12.8% on the provision of most benefits. The calculation of this liability is detailed on the P11D(b) form.

If you would like any help with the completion of forms P11D or the calculation of the Class 1A liability please get in touch.

Employers may wish to complete the forms electronically and submit them online.  For information on this use the online submission link below.
